DESCRIPTION (provided by applicant): The purpose of this research is to create an aesthetic, highly functional, and easily manufactured upper extremity prosthesis that can be field fitted and tailored for use by those with limited financial resources and limited access, both in the United States and worldwide. Two critical components of the prosthetic device will be created: a new, machined plastic prototype of a prosthetic split hook, and a new, machined plastic prototype of elbow components that can be fit to commonly available, inexpensive tubes. The first component prototype will be an injection molded, voluntary opening, split hook terminal device for upper extremity prostheses that is uniquely designed to operate reliably in a variety of environments, including remote, rural areas. The second component prototype will be a molded elbow comprised of two identical tube inserts and two plastic straps. Both new prototypes will have a variety of characteristics that will make them extremely low cost, adaptable to a variety of prostheses, easily maintained, and functional, while still meeting the needs of amputees. In Phase I of this SBIR, we will design and construct alpha prototypes, which will be similar in geometry and dimensions to the expected prosthesis, but will be constructed using numerically controlled machining. The alpha prototypes will be mechanically tested on the bench-top, and distributed to amputees for trial use. Structured interviews with the amputees will verify that the prototypes meet specified design and performance criteria. The interviews will also identify alterations that should be made to improve performance further. Beta prototyping using mass production techniques, and more extensive clinical testing of the split hook and elbow will be reserved for Phase II of this research.

描述（由申请人提供）：本研究的目的是创造一种美观、功能强大且易于制造的上肢假肢，该假肢可以现场安装和定制，供那些在美国经济资源有限且访问渠道有限的人使用各州和全世界。将创建假肢装置的两个关键组件：一个新的、机械加工的假肢裂钩塑料原型，以及一个新的、机械加工的肘部组件塑料原型，可以安装到常用的廉价管子上。第一个组件原型将是用于上肢假肢的注塑成型、自动打开、分体钩终端装置，其独特设计可在各种环境（包括偏远农村地区）中可靠运行。第二个组件原型将是一个模制弯头，由两个相同的管插入件和两条塑料带组成。这两种新原型都具有多种特性，这些特性将使它们成本极低，适用于各种假肢，易于维护且功能齐全，同时仍能满足截肢者的需求。在该 SBIR 的第一阶段，我们将设计和建造阿尔法原型，其几何形状和尺寸与预期的假体相似，但将使用数控加工来建造。阿尔法原型将在工作台上进行机械测试，并分发给截肢者试用。对截肢者进行结构化访谈将验证原型是否符合指定的设计和性能标准。访谈还将确定为进一步提高绩效而应做出的改变。使用大规模生产技术的 Beta 原型制作以及对分体钩和弯头进行更广泛的临床测试将保留到本研究的第二阶段。
