    MAN 1201 A THORACENTESIS SURGICAL SIMULATOR FOR MEDICAL TRAINING

    Get PDF
    Thoracentesis is a surgical procedure involving the drainage of fluid from the pleural space for therapeutic or diagnostic purposes. Emergency surgeons have expressed a need for physiologically accurate surgical models on which medical professionals can train. This paper describes the design of a new model to provide repeatable hands-on training of the Thoracentesis procedure. It uses inexpensive and replaceable materials to mimic the different parts of the thoracic cavity. The penetration force and tensile testing confirmed anatomical accuracy, while Thoracentesis performed by a surgeon on the model confirmed surgical accuracy. We conclude that model is able to bring good function and value to a training need at a low manufacturing cost with quality

    Assessment of Tattoo and Silicone Wounds in Terms of Time of Treatment and Perceived Treatment Quality

    At the point of injury, critical medical tasks include locating and identifying an injury as well as applying the appropriate initial care. Over the past decade, to increase the fidelity of wound representation and ultimately the quality of medical care, a considerable amount of research and development has occurred to improve simulated wounds during training, primarily at the point of injury. As material and techniques mature and as more relevant data is collected on tissue properties, examining what fidelity is required for training at the point of injury is crucial. The main objective of this effort was to assess a three dimensional silicone wound versus a two dimensional tattoo wound for training and to examine differences in user perceptions and treatment time. This was accomplished with a test population of 158 City of Orlando Fire Department First Responders which were randomly assigned to each group (three dimensional silicone wound group versus a two dimensional tattoo wound group). The data analyses incorporated the use of non-parametric statistics (Mann-Whitney U Test) to compare the differences between the two groups on depth perception, sense of urgency, immersion, and time on task. Other factors that were examined included the costs for the average tattoo wound and silicone wound as well as the number of uses before the synthetic wound is visibly damaged. The data results indicated that at the point of injury, there were relatively few statistically significant differences in the survey data or time on task between the silicone and tattoo wounds. Additionally, the cost analysis revealed that the silicone wound is significantly more expensive than the tattoo wound. Supporting the military and civilian first responder communities, the results of this study provides statistically reliable data on the use of trauma tattoos as a tool for mastering point of injury treatment during training exercises

    Wild animals clinical medicine and surgery - Botulism in gulls

    Get PDF
    This report was developed in the context of the Integrated Master's Degree in Veterinary Medicine carried out by the author and was based in her curricular externship at two wildlife hospitals/rehabilitation centres, one located in Spain and the other in the United Kingdom. There are two main parts to this report. The first one includes a description of the activities performed by the author during the externship and data about the animals admitted at both centres. The second part includes a monograph about Botulism in Gulls and a case report of a Lesser Black-backed Gull (Larus fuscus) with botulism. Botulism is one of the most important diseases in wild birds worldwide. Outbreaks of this disease can have high mortality rates and a large impact on wildlife populations; Resumo: Clínica e Cirurgia de Animais Selvagens - Botulismo em Gaivotas Este relatório foi desenvolvido no âmbito do Mestrado Integrado em Medicina Veterinária e foi baseado no estágio curricular realizado pela autora em dois hospitais/centros de recuperação de animais selvagens, um localizado em Espanha e o outro no Reino Unido. Este relatório está dividido em duas partes principais. A primeira inclui uma descrição das atividades desenvolvidas pela autora durante o seu estágio e dados sobre os animais admitidos nos dois centros. A segunda parte inclui uma monografia sobre Botulismo em Gaivotas e um caso clínico de uma Gaivota-d ’asa-escura (Larus fuscus) com botulismo. O botulismo é uma das doenças mais importantes do mundo em aves selvagens. Surtos desta doença podem ter elevadas taxas de mortalidade e um grande impacto nas populações de animais selvagens

    Design and fabrication of silicone-based composite tissue-mimicking phantoms for medical training

    Get PDF
    Silicone-based composite phantoms were fabricated to be used as an education model in medical training. A matrix of silicone formulations was tracked to mimic the ultrasonography, mammography, surgical, and microsurgical responses of different human tissue and organs. The performance of two different additives: i) silicone oil and ii) vinyl-terminated poly (dimethylsiloxane) (PDMS) were monitored with the acoustic setup and evaluated by the surgeons. Breast cancer is one of the most common types of cancer among women, and early diagnosis significantly improves the patient outcomes. The surgeons-in-training necessitate the vast amount of practice to facilitate a noteworthy contribution to this outcome. Therefore, breast simulation models that contain skin layer, inner breast tissue, and tumor structures which allow the collection of samples with biopsy needle were fabricated to be used in ultrasonography, as well as mammography models to be used in tumor diagnostics, and breast oncoplasty models for surgeons to practice their suturing skills. Development of microsurgical techniques signifies a foremost advance in the intervention of the injured peripheral nerves and with the aid of the operating microscopes; it is possible to evaluate the severity of the neural trauma. The advanced microsurgical skills of surgeons are essential for the success of the microsurgery, and in turn for the preservation of the nerve continuity. With this motive, a peripheral nerve phantom that contains skin layer, fascia tissue, epineurium, connective tissue, the fascicles, and the muscle layer has been designed. Herein, we highlight the fabrication of a realistic, durable, accessible, and cost-effective training platform that contains breast ultrasonography, mammography, and oncoplasty models, as well as peripheral nerve with complex hierarchical layers. For training purposes, closest media to reality, fresh cadavers, are hard to obtain due to their price and/or unavailability. Hence, a variety of synthetic tissues were also designed through the optimization of formulations of silicone. Surgical simulation models that mimic various human tissue and organs such as i) multi layers of skin, ii) axilla and axillary lymph nodes, iii) veins, iv) isthmus of the thyroid gland, cricoid cartilage, tongue, larynx, esophagus, tracheal rings, and bronchial tree for the tracheostomy and bronchoscopy models were fabricated

    Micro-motion controller

    Micro-motions in surgical applications are small motions in the range of a few millimeters and are common in ophthalmic surgery, neurosurgery, and other surgeries which require precise manipulation over short distances. Robotic surgery is replacing traditional open surgery at a rapid pace due to the obvious health benefits, however, most of the robotic surgical tools use robotic motion controllers that are designed to work over a large portion of the human body, thus involving motion of the entire human arm at shoulder joint. This requirement to move a large inertial mass results in undesirable, unwanted, and imprecise motion. This senior design project has created a 2-axis micro-motion “capable” platform, where the device studies the most common linear, 2-D surgical micro-motion of pinched human fingers in a damped and un-damped state. Through a system of printed and modeled parts in combination with motors and encoders a microsurgical controller was developed which can provide location-based output on a screen. Mechanical damping was introduced to research potential stability of micro-motion in any surgeon’s otherwise unsteady hand. The device is to also serve as a starter set for future biomedical device research projects in Santa Clara University’s bioengineering department. Further developments in the microsurgical controller such as further scaling, addition of a third axis, haptic feedback through the microcontroller, and component encasing to allow productization for use on an industrial robotic surgical device for clinical applications
