项目摘要

DESCRIPTION (provided by applicant): Owing to certain intrinsic advantages of conventional or cable-operated assistive appliances, many upper- extremity amputees prefer using simple voluntary opening (VO) split hook terminal devices for some tasks. Amputees who regularly contribute their time and expertise helping ADA develop innovative new assistive appliances continue to request the company create for all upper-extremity amputees a refreshing new split hook unit. In particular, three functional innovations are highly desired: 1) a means to readily adjust pinch force; 2) a robust new flex-hinge that is impervious to dirt and debris and that will not jam; and 3) stronger, more functional, and more visually appealing grasping contours. These amputees have further requested that new engineering materials and manufacturing processes be exploited to realize a unit having minimized weight, superior structural strength, and significantly lower manufacturing cost. Beyond this domestic market, the device once developed holds the potential to significantly improve the lives of disadvantaged amputees in developing countries who survive primarily by subsistence farming. Minor adaptations to the underlying technology will maximize its utility for agrarian purposes to enhance these amputees' farming productivity. The Primary Objective of this SBIR program is to create a versatile next-generation VO split hook terminal device that delights upper-extremity amputees in the United States and abroad, and that can be manufactured for low cost to facilitate global distribution. In Phase I, ADA will develop a viable design for its split hook concept implementing the three innovations mentioned previously, and that exploits new materials and manufacturing processes to minimize manufacturing cost. ADA's proven virtual engineering process will yield a viable design, which will then be empirically validated using rapid prototype models. Amputees and professional clinicians will critically examine these models and provide additional feedback and guidance. Following updates to the basic design, robust functional prototypes will be fabricated and evaluated by fifteen (15) human subjects in extensive field validation trials conducted in accordance with an Institutional Review Board (IRB) approved protocol. Phase II comprises conducting additional and unusually demanding trials, establishing manufacturing infrastructure, and adapting the technology for distribution in developing countries by existing O&P clinical outreach humanitarian agencies. Phase III encompasses distributing the new appliance both domestically and overseas to benefit amputees. PUBLIC HEALTH RELEVANCE. ADA aims to create a versatile next-generation split hook terminal device using advanced materials and manufacturing processes that incorporates three functional innovations long sought by amputees who prefer conventional devices for certain tasks. This new split hook satisfies a clear domestic need while offering an attractive low-cost option for disadvantaged amputees in developing countries who need an assistive appliance that enhances their productivity to improve quality of life.

描述（由申请人提供）：由于常规或电缆操作的辅助设备的某些内在优势，许多上肢截肢者更喜欢使用简单的自愿开放（VO）拆分挂钩终端设备来完成某些任务。定期贡献时间和专业知识的截肢者帮助ADA开发创新的新辅助设备，继续要求公司为所有高级amuputees创建一个令人耳目一新的新拆分钩单元。特别是，高度需要三个功能创新：1）轻松调节捏力的一种手段； 2）坚固的新弹性锻炼，对污垢和碎屑不渗透，不会堵塞； 3）更强，功能更强，更具视觉吸引力的抓握轮廓。这些截肢者进一步要求利用新的工程材料和制造工艺来实现一个具有最小化重量，出色结构强度和显着降低制造成本的单位。除了这个国内市场之外，该设备曾经开发的可能会显着改善主要由生存耕作生存的发展中国家处境不利的截肢者的生活。对基础技术的较小适应将最大化其实用性，以提高这些截肢者的农业生产力。该SBIR计划的主要目的是创建一种多功能的下一代VO Split Hook终端设备，使美国和国外的高级截肢者感到高兴，并且可以以低成本制造以促进全球分布。在第一阶段，ADA将为实施前面提到的三个创新的拆分钩概念开发可行的设计，并利用新材料和制造过程以最大程度地减少制造成本。 ADA经过验证的虚拟工程过程将产生可行的设计，然后使用快速原型模型对其进行经验验证。截肢者和专业临床医生将严格检查这些模型，并提供其他反馈和指导。在对基本设计的更新后，将根据机构审查委员会（IRB）批准的协议进行的广泛的现场验证试验，在广泛的现场验证试验中制造和评估强大的功能原型。第二阶段包括通过现有的O＆P临床外展人道主义机构在发展中国家进行额外且异常苛刻的试验，建立制造基础设施，并适应发展中国家的技术。第三阶段包括在国内和海外分发新设备以使截肢者受益。公共卫生相关性。 ADA的目的是使用高级材料和制造过程创建一种多功能的下一代拆分挂钩终端设备，该工艺结合了三种功能创新，而截肢者长期以来一直在寻求他们，他们更喜欢传统设备来执行某些任务。这种新的分钩满足了明确的国内需求，同时为发展中国家的弱势截肢者提供了有吸引力的低成本选择，他们需要辅助设备，以提高其生产力以提高生活质量。
