Abstract:
Suture biomaterials are critical in wound repair by providing support to the healing of different tissues including vascular surgery, hemostasis, and plastic surgery. Important properties of a suture material include physical properties, handling characteristics, and biological response for successful performance. However, bacteria can bind to sutures and become a source of infection. For this reason, there is a need for new biomaterials for suture with antifouling properties. Here we report two types of cellulose fibers from coconut (Cocos nucifera) and sisal (Agave sisalana), which were purified with a chemical method, characterized, and tested in vitro and in vivo. According to SEM images, the cellulose fiber from coconut has a porous surface, and sisal has a uniform structure without internal spaces. It was found that the cellulose fiber from sisal has mechanical properties closer to silk fiber biomaterial using Ultimate Tensile Strength. When evaluating the cellulose fibers biodegradability, the cellulose from coconut showed a rapid weight loss compared to sisal. The antifouling test was negative, which demonstrated that neither possesses intrinsic microbicidal activity. Yet, a weak biofilm was formed on sisal cellulose fibers suggesting it possesses antifouling properties compared to cellulose from coconut. In vivo experiments using healthy mice demonstrated that the scarring and mechanical connection was like silk for both cellulose fibers. Overall, our results showed the potential use of cellulose fibers from vegetal for surgical sutures due to excellent mechanical properties, rapid degradation, and no bacterial adhesion.

Abstract:
Poly(lactic acid) (PLA) suture can be absorbed by the human body, and so have wide applications in modern surgery operations. The degradation period of PLA suture is expected to meet with the healing time of different types of wounds. In order to control the degradation period of the PLA suture, the carbon nanotubes (CNTs) were composited with PLA suture, and the degradation experiment in vitro was performed on sutures. The structure and properties of sutures during degradation, such as surface morphology, breaking strength, elongation, mass and chemical structure, were tracked and analyzed. The results indicated that the degradation brought about surface defects and resulted in 13.5 weeks for the strength valid time of the original PLA suture. By contrast, the strength valid time of the CNTs/PLA suture was increased to 26.6 weeks. Whilst the toughness of both the pure PLA and CNTs/PLA sutures decreased rapidly and almost disappeared after 3 to 4 weeks of degradation. The mass loss demonstrated that the time required for complete degradation of the two sutures was obviously different, the pure PLA suture 49 weeks, while CNTs/PLA sutures 63 to 73 weeks. The research proved that CNTs delayed PLA degradation and prolonged its strength valid time in degradation.

Abstract:
The paper reports about different kind of sutures, their suitability and performance. An ideal suture should possess many characteristics such as - easy to handle, bio-compatibility, minimal tissue reaction, resistance to bacterial growth, adequate tensile strength and elasticity, knot security, strength loss versus healing rate of tissues. Selection of suture is often very complex for satisfying host of physical, mechanical and biological properties, and fulfilling contradictory requirements in varied applications. The paper develops an understanding about the selection of suture depending on the varied requirement. Past research work pertaining to the development of suture as reported in this paper, provides insight about the suitability of different surgical sutures and possible direction of future research.

Abstract:
The main objective of this work is to make an absorbable monofilament suture from Thai rice starch. The improvement of the mechanical properties of Thai rice starch polymer films were achieved by addition of small amount of gelatin, carboxymethylcellulose (CMC) and carbon nanopowders. The carbon nanopowders were produced from coconut shell in our laboratory room by milling method. The incorporation of carbon nanopowders with a high aspect ratio and/or an extremely large surface area into Thai rice starch polymer films improves their mechanical performances significantly. Additionally, the black color from carbon nanopowder is easily visualized in tissue during surgery. The manufacturing processes are very simple by blending of the raw materials in hot water and then dry heating in electric oven. The final product was characterized of microstructures and mechanical properties. The resulting Thai rice starch-carbon nanocomposites possess several advantages for manufacture of sutures: 1. high water resistance that can be uses in the human body. 2. high mechanical strength that appropriate to manufacture of sutures. 3. biocompatibility and bioabsorbable. 4. low cost. 5. Eco-friendly green nanocomposites. However, the method of size designation of sutures fibers and needle attachment are the problem which restricts our suture in really applications. The investigation of knowledge and simple technology of manufacture of suture and needle attachment will be performed.

Abstract:
Background:The aim of this study was to show the effects on the meniscus of repair applied from the femoral, the femoral-tibial and the tibial surfaces.Methods:In the treatment of meniscocapsular separation, although the accepted gold standard technique in the past was the inside-out suture technique, the current treatment method is all-inside repair methods. The all-inside techniques include the hook method and applications with a meniscus suture device. The hook method is difficult with a steep learning curve. In meniscus repair applied with the all-inside meniscus devices, the application of the suture can change the anatomic structure and position of the meniscus.Results:The suturing method applied from the tibial section of the meniscus does not disrupt the anatomic position of the meniscus in meniscocapsular separation. Thus, the optimum conditions are provided for restoration of the functions of the meniscus.Conclusion:The optimal repair in meniscocapsular separations can be considered to be that made with sutures from the tibial section of the meniscus. This technique may be helpful in obtaining better clinical results.

Abstract:
A long-term absorbable monofilament suture was developed using poly-4-hydroxybutyrate (P4HB) made from a biosynthetically produced homopolymer of the natural metabolite 4-hydroxybutyrate. The suture, called MonoMax, has prolonged strength retention. At 12 weeks, a size 3-0 MonoMax suture retains approximately 50% of its initial tensile strengthin vivoand is substantially degraded in one year with minimal tissue reaction. In contrast, PDS II monofilament suture (Ethicon, Inc., Somerville, NJ) has no residual strengthin vivoafter 12 weeks.In vivo, the MonoMax suture is hydrolyzed primarily by bulk hydrolysis, and is then degraded via the Krebs cycle. MonoMax is substantially more compliant than other monofilament sutures, and incorporates an element of elasticity. Its tensile modulus of 0.48 GPa is approximately one-third of the value of the PDS II fiber providing an exceptionally flexible and pliable fiber with excellent knot strength and security. These features are further enhanced by the fiber's elasticity, which also improves knot security and may help prevent wound dehiscence. Because of its performance advantages, this suture may find clinical utility in applications where prolonged strength retention, and greater flexibility are required, particularly in procedures like abdominal wall closure where wound dehiscence is still a significant post-surgical complication.

Abstract:
Purpose: The purpose of this study was to determine the effect of low-pressure and pulsed lavage irrigation on suture knot security. Methods: Ninety-tied suture loops were measured for baseline circumference and then subjected to no irrigation, bulb syringe irrigation, or pulsed lavage irrigation. The sutures were placed under a load and then measured for final circumference. A larger circumference difference indicated poorer knot security. Results: There was a statistically significant difference in the knot security between all three groups ( p < 0.001). Pulsed lavage resulted in the greatest circumference increase (0.52 ± 0.19 mm), followed by bulb syringe (0.24 ± 0.18 mm), and lastly no irrigation (0.08 ± 0.00 mm). None of the groups had any catastrophic failures. No knots met the predetermined criteria for knot failure. Conclusion: Pulsed lavage irrigation resulted in a statistically significant decrease in suture knot security as compared to bulb syringe irrigation and no irrigation. None of the groups met the currently accepted criteria for clinical suture failure, which has a relatively arbitrary value. While the available literature does not discuss increases in loop circumference for specific orthopedic applications, this small difference suggests that pulse lavage is unlikely to have a clinically significant impact on the suture integrity for most orthopedic procedures.

Abstract:
The aim of this project was to address the food waste problem, particularly bread waste, to some extent by producing monofilaments obtained from wet spinning of fungal hydrogel through the cultivation of Rhizopus delemar on bread waste. The project had two phases. Firstly, the possibility of production of chitosan fiber with wet spinning (using different acids) was evaluated, the process was optimized, and then applied to the production of fungal fiber. Regarding first stage of the project, adipic acid, a non-toxic solvent with two carboxyl groups, was used as acting physical crosslinker between the chitosan chains, resulting in improving properties of the monofilaments. Adipic acid performance was compared with conventional solvents, such as citric, lactic, and acetic acids. By injecting chitosan solutions into a coagulation bath (EtOH or NaOH 1M or EtOH-NaOH or H2SO4-EtOH), monofilaments were formed. Scanning electron microscopy showed that uniform chitosan monofilaments with smooth surface were formed using adipic and lactic acids. In general, fibers obtained from adipic acid displayed higher mechanical strength (Young’s modulus of 4.45 GPa and tensile strength of 147.9 MPa) than that of monofilaments produced using conventional solvents. Fiber dewatering with EtOH before drying led to greater fiber diameter and lower mechanical strength. As the second stage of this study, Rhizopus delemar was cultivated on bread waste in shake flasks and 1.3 M3 bioreactor. While different combinations of ground bread and K2HPO4 was used as the substrate for shake flask cultivations, white bread waste without K2HPO4 was utilized for scaling up the process, mostly due to the Glucosamine (GlcN) and N-acetyl-glucosamine (GlcNAc) content in the fungal cell wall. GlcN and GlcNA content obtained from ground bread was remarkably higher than that of obtained from combinations of ground bread and K2HPO4 as the substrate. Cultivation in 1.3 M3 bioreactor resulted in about 36 kg wet biomass with a mean of 14.88% dry weight, indicating 5.95 g biomass/L. The biomass yield of 0.15 g dry biomass/g dry bread was achieved. Alkali insoluble material (AIM) was obtained by alkali treatment of biomass. Fungal hydrogel was prepared by adding adipic and lactic acid to AIM, followed by grinding treatment. While hydrogels treated with lactic acid showed better spinnability and gelling ability, the one from adipic acid was not uniform to be wet spun. Considering hydrogels treated with lactic acid, the optimum grinding cycle for more spinnable hydrogel was 6 negative cycles, contributing to the fibers with the tensile strength of around 82 MPa. Such fibers showed antibacterial property against Escherichia coli, making them as a good option for suture applications. However, further in vitro and in vivo trials are essential to test the fungal fiber for such applications.

Abstract:
"Recent data show that 7.6 million Americans have survived a myocardial infarction (MI), and 5.1 million Americans suffer from severe heart failure. Stem cell therapy has the potential to improve cardiac function after MI. Two promising cells for cardiovascular regeneration therapies include human mesenchymal stem cells (hMSCs) and pluripotent stem cell derived cardiomyocytes (hPS-CM) each with their own unique method for improving cardiac function post-infarct. However, a limiting factor to cell therapies is that the methods currently used to deliver cells to the myocardium, including intramyocardial injection (considered the gold standard), suffer from low retention rates. To promote localization of delivered cells to the infarct and increase retention rates, our lab has developed a fibrin biological suture that can deliver human mesenchymal stem cells (hMSCs) with an efficiency of 64% compared to just 11% with intramyocardial injection in the normal rat heart. In this dissertation we sought to examine the functionality of hMSC and hPS-CM seeded sutures and their impact on cardiovascular regeneration applications. We began by delivering hMSC seeded fibrin sutures to an infarcted rat heart and found that the sutures are an effective method to deliver cells to the infarcted myocardium and demonstrated a trend towards improved regional mechanical function in the infarct region over infarct alone. Next, we transitioned to using hPS-CM and developed methods to seed the sutures, as well as a method to measure hPS-CM contractility with high spatial and temporal resolution, while concurrently capturing calcium transients. This technique allowed us to examine the contractile behavior in terms of contractile strain and conduction velocity of hPS-CM seeded on fibrin microthreads over 21 days in culture. We found that the fibrin microthread is a suitable scaffold for hPS-CM attachment and contraction and that extended culture promotes cell alignment along the length of the suture as well as improvements in contractile function in terms of increases in contractile strain and conduction velocity. Finally, we delivered the hPS-CM seeded microthreads to an uninjured rat heart and found a delivery efficiency of 67%. Overall, we further demonstrated the technology of the fibrin suture to deliver cells to an infarct as well as the ability to support the attachment, contraction and delivery of hPS-CM to cardiac tissue.

Abstract:
Nous étudions des legendriennes à bord, incluses dans une variété de contact (V, ) à bord convexe suturé, et traitons quelques exemples. Tout d’abord on définit l’homologie cylindrique et enroulée d’une legendrienne dont le bord est inclus dans la suture de @V . De plus ces homologies s’inscrivent dans un suite exacte, qui généralise conjecturalement le triangle issu d’un remplissage lagrangien. La construction conormale, appliquée à un sous-variété plongée dans une variété à bord, est un exemple typique d’une telle situation. L’illustration principale concerne les tresses dans une surface épaissie : nous prouvons que les conormaux de deux 2-tresses pures et locales sont isotopes (comme legendriennes à bord fixe) si et seulement si les tresses sont équivalentes. Dans un second temps, nous appliquons la construction conormale à un nœud hyperbolique dans la 3-sphère, et étudions la variété de contact suturée obtenue en retirant un voisinage du conormal du nœud. Nous montrons que l’homologie legendrienne d’une fibre dans cette variété de contact suturée, avec sa structure produit, est un invariant complet du nœud, ce qui peut être vu comme une version suturée d’un récent résultat
We study Legendrians with boundary, in a contact manifold (V, ) with sutured convex boundary, and treat some examples. First we define the cylindrical and wrapped sutured Legendrian homologies of a Legendrian whose boundary is in the suture of @V . Moreover those homologies fit into an exact sequence, which conjecturally generalises the exact triangle arising from a Lagrangian filling. The unit conormal construction, applied to a submanifold embedded in a manifold with boundary, is a typical instance of this situation. The main illustration involves braids in a thickened surface : we prove that the conormals of two local pure 2-braids are isotopic (as Legendrians with fixed boundary) if and only if the braids are equivalent. In a second part, we apply the conormal construction to an hyperbolic knot in the 3- sphere, and study the sutured contact manifold obtained by taking the complement of the unit conormal of the knot. We show that the Legendrian contact homology of a fiber in the sutured contact manifold, with its product structure, is a complete invariant of the knot (up to mirror), which can be understood as a sutured version of a recent result

Abstract:
Virchow a établit, en 1851, une loi empirique permettant d'expliquer les anomalies de croissance consécutives à une synostose crânienne prématurée. L'explication observationnelle qu'il propose établit que l'altération du potentiel de croissance d'une suture synostosée va entraîner une restriction de croissance perpendiculaire à cette dernière. La quasi-totalité des craniosténoses non-syndromiques semblent effectivement répondre au principe de cette loi toujours communément admise. Cependant, dans le cas de la trigonocéphalie (synostose de la suture métopique), cette explication n'est pas suffisante, selon nous, pour expliquer la morphologie très caractéristique en " proue de bateau " de l'avant crâne. Partant de l'hypothèse que des phénomènes mécaniques osseux locaux pourraient en être la cause, notre travail s'est attaché à l'étude biomécanique de la voûte crânienne de l'enfant en croissance. Une classification est tout d'abord proposée pour permettre de classer la sévérité de la déformation triangulaire du front observée dans les trigonocéphalies. Afin de valider et d'analyser les phénomènes décrits par Virchow, une étude de caractérisation mécanique de sutures sténosées a été réalisée, complétée par un modèle numérique basé sur la méthode des éléments finis d'un crâne de nouveau-né. La géométrie a été simplifiée pour permettre de développer des analyses de sensibilités paramétriques. Ce modèle simule la conséquence de la synostose suturaire sur la répartition des contraintes mécaniques osseuses lors de la poussée de croissance encéphalique par un processus non-linéaire de comportement. Dans le cas particulier de la trigonocéphalie, les résultats montrent une anomalie de répartition de ces contraintes sur la suture métopique en cas de sténose précoce, qui pourrait être une explication complémentaire à l'aplatissement des deux os frontaux et à la résultante morphologique triangulaire de l'avant-crâne
In 1851, Virchow establishes an empirical law to explain the anomalies of growth in premature cranial synostosis. Observational explanation he offers, established that the alteration of the growth potential of the affected suture will lead to growth restriction perpendicular to it. Almost all non-syndromic craniosynostosis seem effectively to be in addequation with this principle, still commonly accepted. However, in the case of trigonocephaly (synostosis of the metopic suture), this explanation is not sufficient in our opinion to explain the very characteristic traingular morphology of the forehead. Assuming that local bone mechanical phenomena could be the cause, our work has focused on the biomechanical study of the skull of the growing child. A classification is first proposed to allow to assess the severity of the triangular deformation of the forehead observed in trigonocephaly. To validate and analyze the phenomena described by Virchow, a study of mechanical characterization of stenotic suture was performed, supplemented by a numerical finite element model of the skull of a newborn. This model simulates the result of sutural synostosis on the distribution of bone mechanical stress during the brain growth spurt. Thus, in trigonocephaly, we noticed an abnormal distribution of strain on the metopic suture in cases of early stenosis, which could be an additional explanation for the flattening of the two frontal bones and triangular morphology resulting of the forehead

Abstract:
La thèse porte sur la caractérisation des réservoirs non conventionnels. Elle cherche à intégrer paramètres sédimentologiques, diagénétiques et structuraux dans un réservoir gréseux "tight" pour prédire ses propriétés hydrauliques. Elle concerne la formation des "Quartzites de Hamra", un des réservoirs pétroliers les plus prolifiques des bassins paléozoïques algériens. Cette formation s’est déposée à l’Arenig dans un environnement marin peu profond. Elle a connu au cours de l’enfouissement une diagenèse siliceuse qui a modifié ses propriétés mécaniques et sa porosité. Les fractures, présentes à toutes les échelles, pallient aux faibles caractéristiques matricielles, et leur géométrie est peu précise. La thèse s’est focalisée sur deux cas de terrain, situés sur la zone de suture panafricaine et un champ à gaz localisé dans la partie centrale du bassin de l’Ahnet. L’étude pluridisciplinaire combine plusieurs approches allant de la télédétection aux analyses de laboratoire. Les résultats montrent que les «Quartzites» se sont déposés dans une rampe sableuse, soumise à une forte hydrodynamique tidale. Le système fracturé est en grande partie influencé par la présence des failles. La diagenèse siliceuse a été favorisée par la maturité minéralogique des faciès et leur richesse en quartz monocristallin. La principale source de silice est interne, et liée à la pression-dissolution. A cette histoire de la diagenèse succède une histoire complexe de la déformation, pendant laquelle on assiste à la création de veines en crack-seal, puis à des circulations hydrothermales, d’une précipitation dominée par les hydroxydes de fer et les phosphates
This PHD subject is related to the "Characterization of nonconventional reservoirs". It’s purpose is to understand the interactions between sedimentary facies, fracturation and digenesis in a tight gas reservoir, in order to predict its hydraulic properties. This approach was applied to the "Quarzites de Hamra" formation, which is one of the most prolific reservoirs in the Algerian Paleozoic basins. This formation was deposited during Arenig time, in a shallow marine setting, and underwent during its burial history an important quartz cementation which modified its mechanical properties and porosity. Natural fractures are present at all levels and mitigate low matrix porosities, but their geometric attributes still poorly understood and difficult to predict. The thesis was focused on two field cases, located on the Panafrican suture zone, and a tight gas field located in the central part of Ahnet basin. The multi-disciplinary approach we used integrates satellite imagery, field and well data, and laboratory techniques. The results obtained show that the "Quarzites de Hamra" formation was deposited in a tidal clastic ramp. The fracture system is mainly controlled by the presence of faults. The quartz cementation was favored by the mineralogical maturity of the facies and their high mococristalline quartz content. The source of silica is internal, and related to pressure-solution phenomena. The digenetic history is succeeded by a complex history of deformation, during which a system of veins with crack-seal texture was created, followed by hydrothermal circulations resulting mainly in precipitation of phosphates and iron hydroxides

This research emphasizes what the creativity of the product design process and explores "The Logic of Immediate Negation" in the Diamond Sutra : Because this is not real X; it is (merely) called the X to stimulate the new internal design thinking and creativity. In recent years, Zen had became a pop culture and promoted people to pursue the inner soul and Art. However, in the field of Product Design, the Zen was usually expressed from outside to inside, it was merely to develop the new one from the nature of the product. Hence, this study was used the Zen thinking of the Diamond Sutra to integrate and innovate the impression of the Zen. The findings in this research are as follows: (1) The concept of lateral thinking can be used for each stage by “Noumenon”, “Phenomenon” and “Function”, then to converge those; (2) According to the results of verification by interviewing three related specialists and the case study to improve that “The Logic of Immediate Negation” does have the possibility to enhance the ability to perceive the nature of the product and the quality of design thinking; (3) By the more intelligible way to list those principles to help the future researchers and the designers do the related topic by the Zen thinking.

Parables can inspire wisdom and cultivate the mind. The Illustrated Sutra of the Hundred Parables stories are representative of Buddhist parables, with rich content and are highly interesting, suitable as school instructional materials. The instructional materials used in this paper are the picture book-style The Illustrated Sutra of the Hundred Parables. The picture book-style is easily accepted by children, and the content is full of philosophical knowledge to teach children about how they should engage daily life, and this book can offer children good insight as life education instructional materials. This research explored how The Illustrated Sutra of the Hundred Parables stories are applied in elementary school life education, in order to understand the students’ learning interest for stories in The Illustrated Sutra of the Hundred Parables, and student behavioral changes in the implementation process of life education, to research whether their behavior has been influenced by the course. At the same time, this research discussed how course implementation should be adjusted when combining stories in The Illustrated Sutra of the Hundred Parables with life education, in order to engage in more effective instructional activities. The literature review discussed studies relating to The Illustrated Sutra of the Hundred Parables and life education, and this study used action research to engage in three stages of instructional activities. The subjects were 31 students in the sixth grade, 26 students in the fourth grade, and a 9-person group of students from the second to fourth grade. The course was implemented to observe and record student behavioral performance in class and after class, and conduct data analysis and exploration. The conclusions of this study are as follows: 1. Children have high learning interest for life education course based on The Illustrated Sutra of the Hundred Parables. 2. Implementing the life education course based on The Illustrated Sutra of the Hundred Parables can correct student values, so that students will become more active in their learning attitude, and more willing to face their obstacles and fears. This can also effectively improve interpersonal relationships, enhance the mercy of children, and make them more willing to help others. 3. In the implementation process, issues such as unsuitable story selection and question design affecting instructional effect and class time and location affecting student concentration were found; the most difficult issue to change was students spending too much time playing on the computer. Finally, according to the research results, suggestions are provided for course design, future related studies, and educators, to serve as a reference for future implementation or research in life education.

Full text
Abstract:
Simple craniosynostosis is a cranial deformity that occurs secondary to a premature closure of one or more sutures, with a consequent alteration in cranial growth and cerebral expansion. The cranial alteration presents as flattening parallel to the compromised suture, with compensatory bulging in a perpendicular vector. The surgical treatment consists in cranial decompressions with suturectomies and simultaneous cranioplasties. Dynamic multiple revolution osteotomies allow the design of bone flaps that can help with decompression and correct secondary deformities caused by the synostosis. This multicenter descriptive case series study assessed 52 patients (12 plagiocephaly, 29 scaphocephaly, 7 brachycephaly and 4 trigonocephaly) operated in Cali, Colombia. In each case, suturectomy and telescoping with multiple revolution cranial osteotomies were designed to correct each particular deformity. No clinical complications were observed in the postoperative period (1, 90, and 180 days), and excellent outcomes with no re ossification of sutures and maintenance of the cranioplasty, based on clinical observation and findings in the 3D reconstruction scans.

Abstract:
Trauma and acute care surgery (TACS) constitutes the foundation of emergency surgical services in the United States. Blunt and penetrating traumatic injuries are a leading cause of death worldwide. Non-trauma general surgical emergencies are also a major source of morbidity and mortality. Operative interventions performed within the scope of TACS often revolve around the core principles of contamination control, hemostasis, surgical repair, and subsequent functional restoration. Hemorrhage control is an integral part of emergent operative interventions, and while most instances of surgical bleeding require direct suture ligation or some other form of direct tissue intervention, some circumstances call for the use of adjunctive means of hemostasis. This is especially applicable to situations and settings where direct applications of surgical energy, suture ligation, or direct compression are not possible. Difficult-to-control bleeding can be highly lethal and operative control can be very challenging when confounded by the lethal triad of acidosis, coagulopathy and hypothermia. Topical biosurgical materials (BSM) are of great value in such scenarios, and their use across a variety of settings, from pre-hospital trauma application to emergency general surgery operations, represents an important adjunct to improve patient outcomes. Here we present the different BSMs, discuss their various uses, and provide insight on future applications and developments in this important area.

Full text
Abstract:
Free tissue transfer pursues the best functional and aesthetic results in reconstructive surgery. As these techniques completely maximise the donor tissues’ disposability, these treatments have become a first-line option in many situations. When the donor site is taken form the same patient, these surgeries are often referred to as autotransplants. Free tissue transfer sustains in microvascular anastomosis, which are defined by a vessel lumen diameter inferior to 3 mm. Particular attention to some details is important in these techniques, as, for example, to preclude any damage to the vessel walls or any leakage in the microvascular anastomosis. But the success of these techniques does not only depend on an adequate vascular suture, but also on a constellation of details that must be taken into account. These go from the availability of a trained team, to the ergonomics of the surgeon, through the scrupulous cleanliness of the surgical field.

Abstract:
The development of a remotely operated, Co-Robotic Positioning Device (CRPD) for instrumental backing and optimal base position to robotic arms in tele-surgery is discussed. To optimise the setting of robotic operating rooms (ROR) by reducing the structures’ size around the patient and by selecting task-driven layouts, the design of a hanging servo-carrier coming from the ceiling is chosen, rather than a device located on the floor. The present study prospects a split-duty approach, distinguishing the Co-Robotic Positioning Device, CRPD, from the front-end effectors, each subsystem hierarchically controlled by remote location, in keeping with optimal protocols. The attention is focused on the slave-carrier, to establish an optimal design of the CRPD, based on the characteristics of robotic effectors and the surgical task. The CRPD is conceived to support (up to four) robotic effectors, each one equipped with proper tools (endoscope, scalpels, scissors, suture needles, etc.). The CRPD, actually, by optimally positioning the robotic arms, avoids the need of manual deployment, in current setups often necessary to avoid singularities or collisions. The Automatic Changing Device for Surgical Tools, ACD-ST, is another significant device of the conceived slave-carrier. It allows the tele-operating surgeon to change the tools (scalpels, scissors, etc.) by a direct command from his console. Example applications aim at ticklish endoscopic/tomic operations that require high accuracy with low involved forces such as cardio-thoracic-surgery, abdominal surgery, spine-surgery, microsurgery (neurosurgery, hand-surgery, ophthalmic-surgery, ear-nose-throat surgery), say, the typical domains of MIRS, where robotic surgery is quickly expanding.

Abstract:
Artificial and synthetic skins are widely used in the medical field; used in applications ranging from skin grafts to suture training pads. There is a growing need for artificial skins with tunable properties. However, current artificial skins do not take into account the variability of mechanical properties between individual humans as well as the age-dependent properties of human skin. Furthermore, there has been little development in artificial skins based on these properties. Thus, the primary purpose of this research is to develop variable stiffness artificial skin samples using magnetorheological elastomers (MREs) whose properties that can be controlled using external magnetic fields. In this study, multiple MRE skin samples were fabricated with varying filler particle volume contents. Using a precision dynamic mechanical analyzer, a series of indenting experiments were performed on the samples to characterize their mechanical properties. The samples were tested using a spherical indenter that indented a total depth of 1 mm with a speed of 0.01 mm/s and unloaded at the same rate. The results show that the modulus or stiffness increases significantly as the iron percent (w/w) in the sample increases. Additionally, the stiffness of the sample increases proportional to the intensity of the applied external magnetic field. To assess the MRE samples’ variability of properties, the testing results were compared with in vivo human skin testing data. The results show the MRE samples are feasible to represent the age-dependent stiffness demonstrated in in vivo human skin testing. The MRE materials studied will be further studied as a variable-stiffness skin model in medical devices, such as radial pulse simulators.

Synthetic biodegradable polymers have seen a dramatic increase in their availability and utilization over the last few decades. The first reported biomedical application of biodegradable polymers was during the 70s in biodegradable sutures and to date, it remains as the most widespread usage of this family of materials. Biodegradable polymers have also been proven to be effective carriers in local drug delivery therapies and are widely used as a primary constituent of scaffolds in tissue engineering applications.
