DESCRIPTION (provided by applicant): Prostheses reduce the incidence of contralateral overuse syndrome in upper-limb amputees by encouraging balanced, bimanual limb usage. Benefits include reduced pain and muscular atrophy, increased productivity and self-reliance, improved self-image, a sense of well being, and increased social acceptance. Body- powered prostheses are used extensively in the United States (US) and abroad owing to their relative affordability, high reliability, and excellent utility. Invisible Hand Enterprises (IHE), LLC is developing an innovative biomimetic prehensile digit technology that will extend these benefits to two underserved populations: 1) partial-hand amputees, for whom very few components exist that enable useful grasp, and 2) upper-limb amputees worldwide who need prosthetic terminal devices resembling the anatomical hand with excellent cosmesis and realistic movement for reasons pertaining to social and cultural acceptance. In Phase I of this Small Business Innovation Research (SBIR) program, IHE demonstrated technological and economical viability of its core digit technology. Polymer resins and high-performance textile filaments replicate key structures and functions of the anatomical finger, resulting in devices that are low-cost, lightweight, exceptionally robust, and that require no lubrication. As modular building-blocks, the digits are clinically flexible, enabling prosthetists to create partial-hand prostheses optimized t function in concert with remaining natural digits. Incorporated into a whole-hand terminal device, the digits deliver cosmesis and movements that are psychologically satisfying to amputees, particularly females, and that help deflect attention in regions where stigmas against limb deficiencies are deeply entrenched and often lead to social rejection. In Phase II, IHE will make necessary design refinements and translate its core technology into a modular digit form suitable for commercial distribution. Digits will also be integrated into an existing hand structur, developed previously, that was highly praised by amputee evaluators but rejected for its lack of cable-operation and realistic movement. These products will be clinically evaluated using validated and industry-approved assessment protocols along with extended field performance validations, all performed by volunteer subjects. Manufacturing infrastructure and production processes will be established to support Phase III commercialization activities. Both modular digits and whole hand terminal devices will be brought to market as commercial products using IHE's existing US and international distributors, along with humanitarian agencies. IHE's mission is to delight amputees in the US and abroad by providing affordable new options that help them relish living and enjoy an even higher quality of life. This work is important and worthwhile, and wholly consistent with the spirit and purposes of the National Institute of Health's SBIR program.

描述（由申请人提供）：假体通过鼓励平衡的双层肢体使用来减少上limb amuputees中对侧过度使用综合征的发生率。益处包括减轻疼痛和肌肉萎缩，提高生产力和自力更生，改善自我形象，一种健康感以及增加社会接受。由于其相对可负担性，高可靠性和出色的实用性，在美国（美国）和国外广泛使用了人体动力的假体。无形的手工企业（IHE），LLC正在开发一种创新的仿生型数字学前数字技术，将这些好处扩展到两个人口不足的人群：1）部分手截肢者，对于这些组件而言，有很少的组成部分可以使有用的掌握有用，而2）全球范围内的上限端子却是在全球范围内进行的，并且在全球范围内进行了典范的范围，并且是一种典范的典范，并具有典范的作用。社会和文化接受。在这项小型企业创新研究（SBIR）计划的第一阶段，IHE展示了其核心数字技术的技术和经济可行性。聚合物树脂和高性能纺织细丝复制解剖手指的关键结构和功能，从而产生低成本，轻巧，非常强大的设备，并且不需要润滑。作为模块化建筑块， 数字在临床上是灵活的，使假肢能够与剩余的自然数字共同创建部分手提义务优化t功能。数字纳入全手终端设备中，可以在心理上满足截肢者，尤其是女性，并有助于在针对肢体缺陷的污名上的注意力转移注意力，并经常导致社会拒绝。在第二阶段，IHE将进行必要的设计改进，并将其核心技术转化为适合商业分销的模块化数字形式。数字还将集成到以前开发的现有手部结构中，该结构受到截肢评估者的高度赞扬，但由于缺乏电缆操作和现实的运动而被拒绝。这些产品将使用经过验证和行业批准的评估方案以及扩展的现场绩效验证对临床进行评估，所有这些产品均由志愿者受试者进行。将建立制造基础设施和生产过程，以支持III期商业化活动。模块化数字和整个手终端设备都将通过IHE现有的美国和国际分销商以及人道主义机构作为商业产品将其推向市场。我的任务是通过提供负担得起的新选择来帮助他们享受生活并享受更高的生活质量，以使美国和国外的截肢者感到高兴。这项工作很重要，值得，并且完全符合美国国立卫生研究院SBIR计划的精神和目的。
