DESCRIPTION (provided by applicant): Prosthetics Our goal is to create a "transtibial prosthesis in a kit" that can be inexpensively manufactured using modern technology and advanced polymer materials. This system will be immediately fit on the residual limb and aligned for optimal gait without specialized tools or labs. Such a system alleviates the many steps involved with conventional prosthesis construction which is costly and labor intensive. The primary market for the proposed prosthetic system is impoverished third world countries. The market for such a system is large and consists of foreign healthcare organizations and ministries, the World Health Organization, and the U.S. Military which frequently supports humanitarian missions. A secondary market is in the early rehabilitation of amputees when the limb is changing size and shape in more economically advanced nations. Transtibial amputations due to trauma and dysvascular diseases are the most commonly performed levels of amputation in this country and worldwide and are the focus of this project. Our four year collaboration with Advanced Design Concepts (ADC) engineering firm has been quite successful to date in developing our preliminary prototype design. Continued collaboration with the principal business interest in this study, "iFIT Prosthetics, LLC" will enable us to develop the second generation prosthetic system. In this project, our aims are; i) to design and build the next generation prototype transtibial prosthetic system building on our experience and using a focus group of amputees for consumer input, ii) to conduct a pilot feasibility study on 10 volunteer subjects using biomechanics testing and quantitative surveys, and iii) to derive a final prototype and retest it using finite element analyses in preparation for ISO testing and commercialization. The results of this STTR project could change the way in which lower limb prostheses are provided in underdeveloped nations. The field of lower limb prosthetics can benefit greatly from advanced materials and fabrication techniques. Such innovations hold considerable promise to advance the science and practice of rehabilitation for these individuals. PUBLIC HEALTH RELEVANCE: Prosthetics Our company's goal is to create a "transtibial prosthesis in a kit" that can be inexpensively manufactured using modern technology and advanced polymer materials. This system will be immediately fit on the residual limb and aligned for optimal gait without specialized tools or facilities. Such a system will benefit amputees in impoverished countries as well as amputees in economically advanced nations. This innovative, highly-functional alternative to the current state of prosthetic fabrication holds great potential to advance the quality of life for amputees worldwide.

描述（由申请人提供）：假肢 我们的目标是创造一种“套件中的经胫骨假肢”，可以使用现代技术和先进的聚合物材料廉价地制造。该系统将立即安装在残肢上并调整以获得最佳步态，无需专门的工具或实验室。这种系统减少了传统假肢构造中涉及的许多步骤，这些步骤成本高昂且劳动强度大。所提议的假肢系统的主要市场是贫困的第三世界国家。这种系统的市场很大，由外国医疗机构和部委、世界卫生组织以及经常支持人道主义任务的美国军方组成。在经济发达国家，当肢体的大小和形状发生变化时，截肢者的早期康复就成为二级市场。因创伤和血管障碍性疾病导致的小腿截肢是该国和世界范围内最常见的截肢级别，也是该项目的重点。迄今为止，我们与先进设计概念 (ADC) 工程公司的四年合作在开发初步原型设计方面非常成功。与本研究的主要商业利益公司“iFIT Prosthetics, LLC”的持续合作将使我们能够开发第二代假肢系统。在这个项目中，我们的目标是； i) 根据我们的经验并利用截肢者焦点小组征求消费者意见，设计和构建下一代跨胫骨假肢系统原型，ii) 使用生物力学测试和定量调查对 10 名志愿者受试者进行试点可行性研究，以及 iii)得出最终原型并使用有限元分析对其进行重新测试，为 ISO 测试和商业化做好准备。 STTR 项目的结果可能会改变欠发达国家提供下肢假肢的方式。下肢假肢领域可以从先进的材料和制造技术中受益匪浅。这些创新有望推动这些人的康复科学和实践。 公共健康相关性：假肢 我们公司的目标是创造一种“套件中的经胫骨假肢”，可以使用现代技术和先进的聚合物材料廉价地制造。该系统将立即安装在残肢上并对齐以获得最佳步态，无需专门的工具或设施。这样的系统将使贫困国家的截肢者以及经济发达国家的截肢者受益。这种创新的、高功能的假肢制造替代方案具有巨大的潜力，可以提高全世界截肢者的生活质量。
