Résumé :
Endo surgiclip instrument is the biomedical instrument that can be applied for endoscopic surgery to assist surgeons in homeostasis and secure mucosal gap surfaces during surgical operations. Since some clinic feedbacks show the surgiclip drop-off incidents which can potentially sever organ and tissue, the improvement of endo surgiclip instrument has been made in these years. Since few research papers were involved in the study of endo surgiclip instrument performance via mathematical modeling and computational simulation, currently some instrumental modifications are mainly based on clinic lab tests which prolong the improvement cycle and increase additional manufacturing cost. This paper introduces a new biomedical surgiclip instrument based on mathematical modeling, computer-aided simulation, and prototype testing. The analytic methodology proposed in this paper can help engineers in biomedical industry develop and improve biomedical instrument. Compared to the current conventional surgiclip instruments, this new surgiclip instrument can properly assist surgeon in surgical procedure with less operational force and no surgiclip drop-off incident. The prototype has also been built and tested. Both computational simulation and prototype testing show close results which validate the feasibility of this newly developed endo surgiclip instrument and the methodologies of mathematical modeling based computational simulation proposed in this paper.

Résumé :
Abstract Introduction: Contaminated surgical instruments are manually prepared for cleaning and disinfection in the reprocessing unit for medical devices (RUMED). Manual labour exposes staff to the risk of infection and is particularly stressful at peak times due to the large volume of instruments. Partial automation of processes by a robot could provide a solution but requires a gripper that can handle the variety of surgical instruments. This paper describes the development and first evaluation of an instrument gripper. Methods: First, an analysis of gripping geometries on basic surgical instruments is carried out. Based on the identified common features and a review of the state of the art of gripper technology, the SteriRob gripper concept is developed. The concept is compared with a force closure gripper in a series of tests using seven criteria. Results: Both gripping approaches investigated can be used for handling surgical instruments in a pick-and-place process. However, the SteriRob gripper can transmit significantly higher acting forces and torques. In addition, the gripping process is more robust against deviations from the expected instrument position. Conclusion: Overall, it has been shown that the developed instrument gripper is suitable for about 60% of reusable surgical instruments due to the focus on horizontal cylindrical geometries. Because of the large possible force transmission, this gripping approach is particularly suitable for tasks in which the robot assists with cleaning processes.

Résumé :
Abstract This work presents a sterile concept for 3D cameras within sterile surgical environments. In the digital operating room (OR), such cameras can serve as a valuable data source for cognitive workflow assistance systems, e.g decision or mechatronic support systems. One recent example are robotic assistants for instrument handling, such as the robotic scrub nurse currently developed in the framework of the SASHA-OR research project1. In this context, we detect laparoscopic instruments and the surgical environment with a 3D camera, whereby hygienic requirements need to be met. Using a Zivid Two sensor, we generated point clouds of the laparoscopic instruments located in an instrument holder and a drop zone. We compared the effect of using different pane types and thicknesses for the sterile camera enclosure and compared the performance with and without protective pane in terms of the point cloud accuracy. When analyzing multiple pane types, polymethyl methacrylate with 0.5 mm thickness (PMMA 0.5) provided the best results. At a scan distance of 560 mm to the surface center, which is required for the complete acquisition of a laparoscopic instrument, PMMA 0.5 achieved the smallest Chamfer distance (CD) values for both the scans with the laparoscopic instruments in the instrument holder (0.23 ± 1.52 mm) and in the drop zone (0.12 ± 0.25 mm).

Résumé :
Abstract Under-staffing of nurses is a significant problem in most countries. It is expected to rise in the coming years, making it challenging to perform crucial tasks like assessing a patient's condition, assisting the surgeon in medical procedures, catheterization and Blood Transfusion etc., Automation of some essential tasks would be a viable idea to overcome this shortage of nurses. One such task intended to automate is the role of a 'Scrub Nurse' by using a robotic arm to hand over the surgical instruments. In this project, we propose to use a Collaborative Robotic-arm as a Scrub nurse that can be controlled with voice commands. The robotic arm was programmed to reach the specified position of the instruments placed on the table equipped with a voice recognition module to recognize the requested surgical instrument. When the Surgeon says "Pick Instrument", the arm picks up the instrument from the table and moves it over to the prior defined handover position. The Surgeon can take over the instrument by saying the command "Drop". Safe pathways for automatic movement of arm and handover position will be predefined by the Surgeon manually. This concept was developed considering the convenience of the Surgeon and the patient's safety, tested for collision, noisy environments, positioning failures and accuracy in grasping the instruments. Limitations that need to be considered in future work are the recognition of voice commands which as well as the returning of the instruments by the surgeon in a practical and safe way.

Résumé :
Abstract Minimally invasive procedures such as Natural Orifice Transluminal Endoscopic Surgery (NOTES) require powerful, small, and flexible instruments. A cable-driven instrument was developed, which is able to retract tissue to create sufficient space for an actual operation (e.g. cholecystectomy). In this paper, the work space of a developed instrument is presented. The work space is calculated using direct kinematics equations and verified by measurement using an electromagnetic (EM) tracking system. The angular orientation of the instrument can be up to 85° with a length of the active section of 60 mm. However, a longitudinal rotation up to 17° becomes apparent. This is due to the characteristics of the steel cable used for actuation. Nevertheless, the instrument reaches the intended work space. Further measurements are necessary to evaluate the instrument’s behavior under payload and whether this affects the work space.

Résumé :
The virtual (software) instrument with a statistical analyzer for testing algorithms for biomedical signals’ recovery in compressive sensing (CS) scenario is presented. Various CS reconstruction algorithms are implemented with the aim to be applicable for different types of biomedical signals and different applications with under-sampled data. Incomplete sampling/sensing can be considered as a sort of signal damage, where missing data can occur as a result of noise or the incomplete signal acquisition procedure. Many approaches for recovering the missing signal parts have been developed, depending on the signal nature. Here, several approaches and their applications are presented for medical signals and images. The possibility to analyze results using different statistical parameters is provided, with the aim to choose the most suitable approach for a specific application. The instrument provides manifold possibilities such as fitting different parameters for the considered signal and testing the efficiency under different percentages of missing data. The reconstruction accuracy is measured by the mean square error (MSE) between original and reconstructed signal. Computational time is important from the aspect of power requirements, thus enabling the selection of a suitable algorithm. The instrument contains its own signal database, but there is also the possibility to load any external data for analysis.

Résumé :
There is an ongoing technological revolution in the field of biomedical instruments. Consequently, high performance healthcare devices have led to remarkable economic developments in the medical hardware industry. Until now, nearly all optical bio-imaging systems are based on the 2-dimensional imaging chip architecture. In fact, recent developments in digital micromirror devices (DMDs) are gradually making their way from conventional optical projection displays into biomedical instruments. As an ultrahigh-speed spatial light modulator, the DMD may offer a range of new applications including real-time biomedical sensing or imaging, as well as orientation tracking and targeted screening. Given its short history, the use of DMD in biomedical and healthcare instruments has emerged only within the past decade. In this paper, we first provide an overview by summarizing all reported cases found in the literature. We then critically analyze the general pros and cons of using DMD, specifically in terms of response speed, stability, accuracy, repeatability, robustness, and degree of automation, in relation to the performance outcome of the designated instrument. Particularly, we shall focus our discussion on the use of Micro-Electro-Mechanical System (MEMS)-based devices in a set of representative instruments including the surface plasmon resonance biosensor, optical microscopes, Raman spectrometers, ophthalmoscopes, and the micro stereolithographic system. Finally, the prospects of using the DMD approach in biomedical or healthcare systems and possible next generation DMD-based biomedical devices are presented.

Résumé :
The majority ofin vivoapplications of near-infrared spectroscopic (NIRS) monitoring use continuous wave instruments that require a fiberoptic cable connection between the subject and the instrument during monitoring. In studies of muscle physiology where subjects are exercising, and particularly in those who are engaged in sports activity, a wireless instrument with telemetric capacity provides obvious advantages. Having access to reliable telemetric NIRS technology will also increase the practicality and scope of this biomedical monitoring technique in clinical settings.We report the feasibility of using a wireless continuous wave NIRS instrument with light emitting diodes, spatially resolved configuration, and Bluetooth®capability to study skeletal muscle oxygenation and hemodynamics during isometric contraction and ischemia induction.In ten healthy subjects comparable patterns of change in chromophore concentration (oxygenated and deoxygenated hemoglobin), total hemoglobin and muscle oxygen saturation were observed during 3 sets of isometric voluntary forearm muscle contraction at 10, 30 and 50% of maximum voluntary capacity (MVC), and a period of ischemia generated subsequently.This small series indicates that data with good intra- and inter-subject reproducibility that is free of movement artifact can be obtained with the wireless NIRS instrument described. The validity of these muscle studies demonstrate a basis for applying wireless NIRS monitoring to publisher-id biomedical applications.

Résumé :
The MicroTactus is an instrument designed to detect signals arising from the interaction of a tip with soft or hard objects and to magnify them for haptic and auditory reproduction. An enhanced arthroscopic surgical probe was developed using an accelerometer and a custom-designed actuator for haptic feedback. Measurements were made to characterize the device and the results showed that numerous factors such as gripping method and gripping force influenced the system response in a complicated manner. The device was tested with the task of detecting surface defects of a cartilage-like material. Subjects were asked to detect the cuts of different depths under four conditions: no amplification, with haptic feedback, with sound feedback, and with passive touch. Both haptic and auditory feedback was found to significantly improve detection performance, which demonstrated that an enhanced arthroscopic probe provided useful information for the detection of small cuts in tissue-like materials.

Résumé :
For this research project we designed an instrument to detect bacteria via biomolecular fluorescence. We introduce the current understanding of astrobiology, our knowledge of life beyond Earth, and the commonality of Earth life as it pertains to the search for life on Mars. We proposed a novel technique for searching for direct evidence of life on the surface of Mars using fluorescence. We use the arid region of the Mojave Desert as an analog of Mars. Results indicate the fluorescence of the biotic component of desert soils is approximately as strong as the fluorescence of the mineral component. Fluorescence laboratory measurements using the portable instrument reveal microbial concentration in the Mojave Desert soil is 107 bacteria per gram of soil. Soil microbial concentrations over a 50 meter area in the Mojave Desert, determined in situ via fluorescence, show that the number varies from 104 to 107 cells per gram of soil. We then designed an instrument for detection of biomolecular fluorescence, and considered also fluorescence from polycyclic aromatic hydrocarbons and minerals on the Martian surface. The majority of the instrument is designed from Mars surface operation flight qualified components, drastically reducing development costs. The basic design adapts the ChemCam instrument package on-board Mars Science Laboratory rover Curiosity to detect organics via fluorescence. By placing frequency multipliers in front of the 1064 nm laser, wavelengths suitable for fluorescence excitation (266 nm, 355 nm, and 532 nm) will be achieved. The emission system is modified by the addition of band pass filters in front of the existing spectrometers to block out the excitation energy. Biomolecules and polycyclic aromatic hydrocarbons are highly fluorescent at wavelengths in the ultra violet (266 nm, 355 nm), but not as much in the visible 532 nm range. Preliminary results show minerals discovered, such as perchlorate, fluoresce highest when excited by 355 nm. Overall, we conclude the fluorescent instrument described is suitable to detect soil microbes, organics, biomolecules, and some minerals via fluorescence, offering a high scientific return for minimal cost with non-contact applications in extreme environments on Earth and on future missions to Mars.

Résumé :
Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2007.
Includes bibliographical references (leaves 46-48).
Interest in micro-optical components for applications ranging from telecommunications to the life sciences has driven the need for accessible, low-cost fabrication techniques. Most micro-lens fabrication processes are unsuitable for applications requiring 100% fill factor, apertures around 1 mm, and scalability to large areas with millions of lenses. A flexible, low-cost mold fabrication technique that utilizes a combination of milling and micro-forging is reported. The technique involves first performing a rough cut with a ball-end mill. Final shape and sag height are then achieved by pressing a sphere of equal diameter into the milled divot. Using this process, molds were fabricated for rectangular arrays of 1-10,000 lenses with apertures of 0.25-1.6 mm, sag heights of 3-130 [mu]m, inter-lens spacings of 0.25-2 mm, and fill factors of 0-100%. Mold profiles have roughness and figure error of 68 nm and 354 nm, respectively, for 100% fill factor, 1 mm aperture square lenses. The required forging force was modeled as a modified open-die forging process and experimentally verified to increase nearly linearly with surface area.
(cont.) The optical performance of lens arrays injection molded from micro-forged molds was characterized by imaging the point spread function, and was found to be in the range of theoretical values. Limitations include milling machine range and accuracy. Application to biological fluorescence detection in a biomedical device is also reported.

Résumé :
Bakgrund: Natrium (Na+) är en viktig elektrolyt i kroppen, och analyseras bland annat för att kunna bedöma patientens tillstånd och för att avgöra om akut behandling är nödvändigt. Analysen av Na+ på intensivvårdsavdelningen (IVA) i Örebro sker med hjälp av GEM Premier 5000, vilket är ett patientnära instrument som använder direkt metod för analys av helblod. Vid patientprovsjämförelse skickas provet vidare till centrallaboratoriet där plasman analyseras genom indirekt metod på Advia Chemistry XPT. Avvikelse mellan metoderna får inte överstiga 3%, annars måste orsaken utredas.  Syfte: Syftet med arbetet är att undersöka om det finns en systematisk skillnad på natrium-resultat mellan patientnära instrument, Gem Premier 5000 och centrallaboratoriets instrument, Advia Chemistry XPT hos olika patientgrupper. Metod: Mätning utfördes på blodprover tagna i litium-heparin rör på 60 deltagare, varav 30 var friska blodgivare (grupp 1) och resterande 30 bestod av inneliggande patienter (IVA) samt njurdialys-patienter, (grupp 2). Proverna analyserades för natrium i helblod på GEM Premier 5000 och strax därefter analyserades natrium, albumin, totalt protein, C-reaktivt protein (CRP), glukos och triglycerider i plasma på Advia Chemistry XPT. Resultat: Advia Chemistry XPT gav en högre medelkoncentration av Na+ (139 mmol/L) än GEM Premier 5000 (138 mmol/L) sett till samtliga deltagare. Procentuella skillnaden för natrium mellan metoderna översteg 3% för 3 deltagare i grupp 1 respektive hos hälften av deltagarna i grupp 2.   Slutsats: Na+ resultat på Advia Chemistry XPT var högre än på GEM Premier 5000 för alla deltagare. Skillnaden var större hos patienter med hög grad av sjuklighet. Detta antyder att nuvarande acceptabla avvikelse på 3% bör höjas till 5%, för att antal avvikande värden ska reduceras till nästan samma för båda grupper. Detta måste övervägas och implementeras i verksamheten.
Background: Sodium (Na +) is an important electrolyte in the body, and is analyzed, among other things, to be able to assess the patient's condition in the intensive care unit (IVA) and to determine if emergency treatment is necessary. The analysis of Na + on IVA is done with the help of GEM Premier 5000, which is a patient-centered instrument and uses a direct method for analysis of whole blood. For patient sample comparison, the sample is sent to the central laboratory where the plasma is analyzed by indirect method on Advia Chemistry XPT. Deviation between the methods must not exceed 3%, otherwise the cause must be investigated. Aim: The aim of the study is to investigate whether there is a systematic difference in Sodium results between patient-related instruments, Gem Premier 5000 and the central laboratory's instrument, Advia Chemistry XPT in different patient groups. Method: Measurement was performed on blood samples taken in Lithium Heparin tubes of 60 participants, of which 30 were healthy blood donors (group 1) and the remaining 30 consisted of inpatients (IVA) and kidney dialysis patients, (group 2). The samples were analyzed for sodium on GEM Premier 5000 and shortly thereafter for sodium, albumin, total protein, C-reactive protein (CRP), glucose and triglycerides on Advia Chemistry XPT. Results: Advia Chemistry XPT gave a higher concentration of Na + (139 mmol / L) than GEM Premier 5000 (138 mmol / L) for all participants. The percentage difference of Na between the methods differed for 3 participants in group 1 while it differed for half of the participants in group 2. Conclusion: Na + results on Advia Chemistry XPT were higher than on GEM Premier 5000 for all participants. The difference was greater in patients with a high degree of morbidity. This suggests that the current acceptable deviation of 3% should be increased to 5%, in order to reduce the number of deviating values ​​to almost the same for both groups. This must be taken into account and implemented in the business.

Résumé :
Manipulation of large internal organs, e.g., spleen, kidney, and liver, is a demanding but challenging task during laparoscopic surgery using conventional miniature instruments. Recently fingered hand instruments have been proposed for doing this task which are assembled/disassemble inside the patient’s abdomen [1–3]. They are not, however, feasible for use in real surgeries considering the substantial time needed for their setting up process. This paper describes the conceptual design of an effective laparoscopic instrument for manipulation of large human organs. A novel mechanism is presented which enables the instrument to pass through a 10 mm trocar to enter the abdominal cavity when it is closed, and grasp body organs, as large as 80 mm diameter, when it is opened. It is shown that the instrument can be used effectively for laparoscopic surgery operations without the need to an assembling/disassembling procedure.

Résumé :
It is called contracture that a joint’s range of motion is restricted. Range of motion exercise is effective to prevent contracture. However, if range of motion exercise by the physiotherapist is performed, a range of motion will improve, but if time not to exercise is long, contracture will decrease again. Then, a rehabilitation instrument for passive range-of-motion exercise which can use after exercise by the physiotherapist is required. A CPM for a knee is developed as such an instrument, and it is also used for an ankle. But, most of instrument used motors to get a high power. So, those are heavy and large size. Installation and movement of instruments at facilities are difficult, and it is also difficult to use freely at home.
