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(申请人提供)：由于传统或缆绳操作的辅助器具的某些固有优点，许多上肢截肢者更喜欢使用简单的自愿开启(VO)分裂钩终端装置来执行某些任务。截肢者经常贡献他们的时间和专业知识帮助ADA开发创新的新辅助器具，他们继续要求该公司为所有上肢截肢者创造一个令人耳目一新的新分裂钩单元。特别是，人们非常希望有三项功能创新：1)一种随时调整夹紧力的方法；2)一种坚固的新弹性铰链，它不受灰尘和碎片的影响，不会卡住；以及3)更强大、更实用、更具视觉吸引力的抓取轮廓。这些截肢者进一步要求开发新的工程材料和制造工艺，以实现具有最小重量、更好的结构强度和显著降低制造成本的单元。在这个国内市场之外，一旦开发出这种设备，就有可能显著改善发展中国家弱势截肢者的生活，这些人主要靠自给自足的农业生存。对基础技术进行较小的调整将最大限度地提高其对农业的效用，以提高这些截肢者的农业生产力。该SBIR计划的主要目标是创造一种多功能的下一代VO分叉钩终端设备，使美国和国外的上肢截肢者感到高兴，并且可以低成本制造，以促进全球分销。在第一阶段，ADA将为其拆分挂钩概念开发一种可行的设计，实现前面提到的三项创新，并利用新材料和制造工艺将制造成本降至最低。Ada经过验证的虚拟工程过程将产生一个可行的设计，然后将使用快速原型模型进行经验验证。截肢者和专业临床医生将严格检查这些模型，并提供额外的反馈和指导。在对基本设计进行更新后，将根据机构审查委员会(IRB)批准的协议，由十五(15)名人类受试者在广泛的现场验证试验中制造和评估坚固的功能原型。第二阶段包括进行额外的和异常苛刻的试验，建立制造基础设施，并调整技术，以便由现有的O&P临床推广人道主义机构在发展中国家分发。第三阶段包括在国内和海外分发新设备，使截肢者受益。与公共卫生相关。Ada的目标是使用先进的材料和制造工艺创造一种多功能的下一代分叉钩终端设备，该设备结合了截肢者长期以来寻求的三项功能创新，他们更喜欢使用传统设备来执行某些任务。这种新的分叉钩满足了明显的国内需求，同时为发展中国家的弱势截肢者提供了一个有吸引力的低成本选择，他们需要一种能够提高生产力以改善生活质量的辅助器具。
