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.

拟议项目的目的是设计和开发纯机械的赛车假肢手指 - 女性数字 - 哪个可以使用高级金属3D打印来尺寸为第五百分位女性手 技术，2）具有行业领先的体重比，以及3）可以单方面运行（一个 - 手动）使用一种新型的赛车机制。 上肢上肢最大的人口是那些有部分手截肢的人。这个人口 人数超过所有其他级别的上肢截肢者的倍数为10倍。因此，显着的临床影响可以 如果产品有效地为该人群服务，则可以制作。但是，目前用于部分手的商业产品 截肢者不满足女性患者的所有需求；没有商业可用的假肢手指是 适当的尺寸适合各种女性手尺寸。有效地，某些有部分手的女退伍军人 截肢不可治疗。 该建议是对VA RR＆D提案请求（RFP）的回应 假肢成分。拟议的研究计划包括1）妇女的设计和开发 数字 - 赛车机械假肢手指，2）在各个长度上制造多个原型， 3）机械测试以确认可伸缩性，强度，可靠性和制造业，以及4）实验室 与女性部分手截肢者进行测试。 上肢截肢的退伍军人需要一种高度个性化的医学方法。每个 资深人士为诊所带来了独特的需求，包括各种截肢，生活方式，个人经验， 和其他医疗指标。假肢主义者和占领治疗师与每位退伍军人合作，以提供 使用任何组件和技术的个性化医疗解决方案在公开市场上可用。 通常，该系统中的瓶颈是临床上合理的假肢成分的发展 假肢主义者很容易提出一个最佳的假肢系统。 VA生物学发展实验室的使命是创新的设备和算法 上肢假体设计的领域。生物学发展开发实验室开发产品，这些产品 在这种动态和 具有挑战性的医疗保健设置。妇女的数字将为妇女提供有效耐用的解决方案 退伍军人的退伍军人，并确保他们充分享受自己的工作，家庭和生活的能力。
