Book excerpt: Additive manufacturing AM is an emerging technology that offers the ability to create parts without moulds, material wastage or labour. This offers a wide range of industries to rapidly produce both prototypes and end use products with extraordinary design freedom and a high level of customisation. The widely used AM methods are limited in the working materials which are most commonly high cost, heavy metals or low cost and performance plastics. Options for the AM of composite materials are limited, yet they are the material of choice for high performance applications. Modern composite materials are used to manufacture light-weight structures with high strength to weight ratios. The manufacture of composites is largely dependent on skilled labour, customised moulds and expensive tooling which are all manufacturing complexities that additive manufacturing eliminates. The additive manufacture of long fibre thermoset composites is an opportunity which is currently a topic of research at the University of Auckland. There are many industries which seek to benefit from long fibre 3d printing but the decision on the market entry point for such a technology is a multi-variant problem. Market research indicated that the prosthetics manufacturing industry to be a suitable market entry point. The manufacturing complexities associated with composite manufacture are exaggerated in this industry due to the need to meet the unique requirements of each patient and the New Zealand industry has expressed a strong desire to adopt new technology. The purpose of the project described in this thesis is to acquire knowledge about the requirements of prosthetic design and manufacture for the application of composite 3d printing. Interviews and work shadowing with the New Zealand Artificial Limb Service NZALS was conducted in order to understand the process behind manufacturing prosthetics. Laminate modelling and analysis followed by experimental validation showed the fibreglass laminates used by the NZALS to have an ultimate tensile stress between 50MPa and 60MPa. The strength and stiffness of the NZALS socket laminates was used determined the target volume fraction for printing to be 30% carbon fibre. Finite element analysis was used to further investigate the performance requirements of prosthetic sockets by modelling their structural behaviour. Test methods prescribed by ISO 10328 were used to develop a modelling methodology to analyse the response of a socket under load and the performance of laminates used. The model was validated using experimental data with predicted strain within 20% of the experimentally measured strain in critical areas of the socket. This model can now be used as a tool to work with the NZALS to further refine their socket lamination methods. The mechanical properties of socket laminates can now be quantified and compared such that more informed decisions can be made to improve current socket lamination practice. This modelling procedure also enables new materials created with 3d printing to be evaluated against current material systems to provide prosthetists and amputees more confidence in emerging digital manufacturing methods.

This book was released on 2020-12-18 with total page 791 pages. Available in PDF, EPUB and Kindle. Book excerpt: Along with the introduction of technology in nearly every facet of human life comes the question of the ethical side of using technology to improve the human condition, whether that be physically or mentally. The capabilities of human enhancement technologies have created a dual-sided approach to discussing human enhancement: the critical approach of attempting to reach human perfection and the ethics within that idea and the endless capabilities of technology that have greatly impacted the medical field. It is essential to discuss both aspects within these emerging technologies, whether as separate entities or as cohesive units. Ranging from disease detection and treatment to implants and prosthetics to robotics and genetic engineering, human enhancement technologies are widespread and multi-purposed. By going beyond the capabilities of human hands, these technologies have propelled modern medicine and healthcare to new levels that have allowed humans to face new treatments or assistive technologies not seen before. The Research Anthology on Emerging Technologies and Ethical Implications in Human Enhancement covers the primary technologies and tools being used in medicine and healthcare along with discussions on the ethics of enhancing the human body. Topics covered include prosthetics and implants, robotics, human disorders/diseases and treatments and smart technologies, along with law and theory. This publication serves as a valuable reference work for doctors, medical professionals, researchers, students, professionals, and practitioners involved in fields that include ethics, medicine, computer science, robotics, genetics, assistive technologies, nanotechnology, biomedical engineering, and biotechnology.

The National Academies Keck Futures Initiative was launched in 2003 to stimulate new modes of scientific inquiry and break down the conceptual and institutional barriers to interdisciplinary research. The National Academies and the W.M. Keck Foundation believe considerable scientific progress and social benefit will be achieved by providing a counterbalance to the tendency to isolate research within academic fields. The Futures Initiative is designed to enable researchers from different disciplines to focus on new questions upon which they can base entirely new research, and to encourage better communication between scientists as well as between the scientific community and the public. Funded by a $40 million grant from the W.M. Keck Foundation, the National Academies Keck Futures Initiative is a 15-year effort to catalyze interdisciplinary inquiry and to enhance communication among researchers, funding agencies, universities, and the general public with the object of stimulating interdisciplinary research at the most exciting frontiers. The Futures Initiative builds on three pillars of vital and sustained research: interdisciplinary encounters that counterbalance specialization and isolation; the identification and exploration of new research topics; and communication that bridges languages, cultures, habits of thought, and institutions. Toward these goals, the National Academies Keck Futures Initiative incorporates three core activities each year: Futures conferences, Futures grants, and National Academies Communication Awards.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prosthetic socket, an essential interface element between the patient's stump and prosthetic device, is most often the place where the degree of prosthetic success is defined. It is the most critical part of the prosthesis, customized to fit with the unique residual limb of the amputee. Without a proper socket shape and fit, the prosthesis becomes uncomfortable, or even unusable, and causes pain and skin issues. The state-of-the-art prosthetic production is still missing universal numerical standards to design a socket. The current practice is expensive and relies on the manual refinements of the orthopedic technician, and the fit quality strictly correlates with his skills as well as the subjective feedback of the patient. The thesis aims to conduct a deep analysis of an optimal design of the prosthetic socket by studying and developing an alternative computer-aided design process. This process is fully based on the virtual model of the patient's residual limb and relies on the calculation of the socket-stump interaction. A fast calculation is favorable in this case, that's why we propose to use the Mass-Spring System (MSS) instead of the widely used FE method to model the soft tissues of the residual limb. A new configuration of the MSS model is proposed to respect the non-compressibility property of the soft tissues by adding non-linear “Corrective Springs”. The numeric model is to be generated from the scanned model of the stump. For this purpose, we propose a fusion scheme of four RGB-Depth sensors for a rapid and low-cost scan with error reduction techniques. Finally, the virtual residual limb is used in the socket designing phase. A parametric design method is proposed and investigated. The design problem is transformed into a constraint-satisfaction-problem whose constraints are derived from the inverse calculation of the stump-socket interaction. The inverse approach has been chosen to eliminate the need for expensive contact formulation. This fact leads to rapid calculations, and consequently, allows to provide real-time numerical feedback during the designing process. The validation was done by comparing the results of our system with the output of FE simulations. The system has been implemented with a user-friendly graphical interface and virtually tested and numerically validated. This system reduces the limitations of the current practices. However, a lot of works is still ahead to refine and develop the system and validate it with clinical experiments.

Download or read book CAD CAM in Medical Prosthesis written by Vajvinder Kumar and published by Meem Publishers. This book was released on 2023-08-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) are technologies used in various industries, including the field of medical prosthetics. These technologies play a crucial role in designing and producing high-quality, customized medical prostheses for individuals with limb loss or other physical impairments. Here's how CAD/CAM is applied in the creation of medical prostheses: CAD in Medical Prosthesis: CAD involves creating digital models and designs using specialized software. In the context of medical prosthetics, CAD is used to design and visualize prosthetic devices based on the patient's anatomy and specific needs. Here's how CAD is applied: Patient-Specific Design: CAD software allows prosthetists (professionals who design and fit prostheses) to create patient-specific designs. They can input the patient's measurements and anatomical data to develop a prosthetic limb that fits and functions optimally for that individual. Customization: CAD enables prosthetists to customize the shape, size, and features of the prosthetic limb. This can be particularly important for prostheses that need to mimic the natural appearance and movement of body parts. Virtual Prototyping: CAD models can be used to create virtual prototypes of prostheses. This allows for design iterations and modifications before moving to the manufacturing phase, reducing the chances of errors or discomfort for the patient. CAM in Medical Prosthesis: CAM involves the use of software and machinery to automate the manufacturing process based on the CAD designs. In the context of medical prosthetics, CAM is used to produce the physical prosthetic device from the digital design. Here's how CAM is applied: Computer-Controlled Manufacturing: CAM software takes the CAD model and generates toolpaths for manufacturing machines, such as 3D printers or CNC milling machines. These machines follow the programmed instructions to create the physical prosthetic device. 3D Printing: Additive manufacturing, often referred to as 3D printing, is a common CAM technique used in prosthetics. It allows for precise layer-by-layer construction of complex prosthetic designs using materials like plastics, metals, or composites. CNC Machining: Computer Numerical Control (CNC) machines can be used to carve prosthetic components from blocks of materials. This is often used for creating prosthetic sockets and other components that require high precision. The integration of CAD and CAM technologies in the field of medical prosthetics has led to more accurate, efficient, and patient-specific designs. It enables prosthetists to create functional and comfortable prosthetic devices that significantly improve the quality of life for individuals with limb loss or mobility impairments

This book was released on 2017-09-01 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Census Bureau has reported that 56.7 million Americans had some type of disability in 2010, which represents 18.7 percent of the civilian noninstitutionalized population included in the 2010 Survey of Income and Program Participation. The U.S. Social Security Administration (SSA) provides disability benefits through the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. As of December 2015, approximately 11 million individuals were SSDI beneficiaries, and about 8 million were SSI beneficiaries. SSA currently considers assistive devices in the nonmedical and medical areas of its program guidelines. During determinations of substantial gainful activity and income eligibility for SSI benefits, the reasonable cost of items, devices, or services applicants need to enable them to work with their impairment is subtracted from eligible earnings, even if those items or services are used for activities of daily living in addition to work. In addition, SSA considers assistive devices in its medical disability determination process and assessment of work capacity. The Promise of Assistive Technology to Enhance Activity and Work Participation provides an analysis of selected assistive products and technologies, including wheeled and seated mobility devices, upper-extremity prostheses, and products and technologies selected by the committee that pertain to hearing and to communication and speech in adults.
