The goal of the proposed project is to design and develop a purely mechanical, ratcheting prosthetic finger – the Women’s Digit – which 1) can be sized for a 5th percentile female hand using advanced metal 3D printing technology, 2) has an industry leading strength to weight ratio, and 3) can be operated using unilaterally (one- handed) using a novel ratcheting mechanism. The largest population of upper limb amputees are those with partial hand amputations. This population outnumbers all other levels of upper limb amputees by a factor of 10. Therefore, a significant clinical impact can be made if a product serves this population effectively. However, current commercial products for partial hand amputees do not satisfy all of the needs of female patients; no commercially available prosthetic finger is appropriately sized for the full range of female hand sizes. Effectively, certain women veterans with partial hand amputation are untreatable. This proposal is in response to the VA RR&D Request for Proposals (RFP) to develop female veteran specific prosthetic components. The proposed research plan includes 1) the design and development of the Women’s Digit – a ratcheting mechanical prosthetic finger, 2) the manufacturing of multiple prototypes at various lengths, 3) mechanical testing to confirm scalability, strength, reliability, and manufacturability, and 4) an in-laboratory testing session with a female partial hand amputee. The care of Veterans with upper limb amputation requires a highly individualized approach to medicine. Each Veteran brings unique needs to the clinic including various levels of amputation, lifestyles, personal experience, and other medical indicators. Prosthetists and occupational therapists work with each Veteran to provide a personalized medical solution using whatever component and technologies are available on the open market. Very often, the bottleneck in this system is the development of clinically sound prosthetic components that can be readily sourced by the prosthetists to provide an optimal prosthetic limb system. The mission of the VA Biomechatronics Development Laboratory is to innovate devices and algorithms in the field of upper limb prosthetic design. The Biomechatronics Development Laboratory develops products that provide prosthetists and Veterans with solutions to meet the unique needs of each Veteran in this dynamic and challenging healthcare setting. The Women’s Digit will provide an effective and durable solution for women veterans with partial hand amputation and ensure their ability to enjoy their work, family, and life to the fullest.

该项目的目标是设计和开发一种纯机械的棘轮假肢手指—— 女性手指 – 1) 可以使用先进的金属 3D 打印来调整 5% 女性手的尺寸 技术，2）具有行业领先的强度重量比，3）可以单边操作（单向操作） 使用新颖的棘轮机构。 上肢截肢者中最大的一部分是手部部分截肢的人。 上肢截肢者的数量是所有其他级别的上肢截肢者的十倍。因此，显着的临床影响可以 如果产品能够有效地服务于这一人群，那么目前的商业产品就属于部分手工。 截肢者不能满足女性患者的所有需求；没有市售的假肢手指 尺寸适合所有女性手部尺寸，有效地适合某些手部偏小的女性退伍军人。 截肢是无法治疗的。 该提案是为了响应 VA RR&D 提案请求 (RFP)，以开发女性退伍军人专用产品 拟议的研究计划包括 1) 女性假肢的设计和开发。 Digit – 棘轮机械假肢手指，2) 制造不同长度的多个原型， 3) 机械测试，以确认可扩展性、强度、可靠性和可制造性，以及 4) 实验室内 对女性部分手截肢者进行测试。 上肢截肢退伍军人的护理需要高度个性化的医疗方法。 退伍军人为诊所带来了独特的需求，包括不同程度的截肢、生活方式、个人经历、 和其他医疗指标。假肢师和职业治疗师与每位退伍军人合作，提供一个 使用公开市场上可用的任何组件和技术的个性化医疗解决方案。 通常，该系统的瓶颈是开发临床上可靠的假肢部件，这些部件可以 假肢专家可以轻松采购以提供最佳的假肢系统。 VA 生物机电一体化开发实验室的使命是创新设备和算法 上肢假肢设计领域。生物机电一体化开发实验室开发的产品 为假肢师和退伍军人提供解决方案，以满足每位退伍军人在这个充满活力和变化的环境中的独特需求 具有挑战性的医疗保健环境将为女性提供有效且持久的解决方案。 帮助部分手部截肢的退伍军人，确保他们能够充分享受工作、家庭和生活。
