A ratcheting pediatric prosthetic finger using advanced rapid manufacturing technology ABSTRACT The goal of the proposed project is to develop and commercialize a purely mechanical, ratcheting pediatric prosthetic finger – the Point Mini – which 1) has an industry leading strength to weight ratio, 2) can be operated unilaterally (one-handed), 3) offers anatomical rotation and flexion around the patient’s metacarpophalangeal (MCP) joint, and 4) can be custom-made for each patient using advanced metal 3D printing technology. The care of pediatric patients with partial hand limb absence requires a highly individualized approach. Each child and their family bring unique needs to the clinic including various levels of amputation, lifestyles, personal experience, and other medical indicators. Prosthetists and occupational therapists work with each patient and their family to provide a personalized medical solution using whatever components and technologies are available. Very often, the bottleneck in this system is the availability of clinically sound prosthetic components that can be readily sourced by the prosthetists to provide an optimal prosthetic limb system, especially for the pediatric patient population. The largest population of people with upper limb loss are those with partial hand limb absence. This population outnumbers all other levels of people with upper limb loss by a factor of 10. Therefore, we can make a significant clinical impact if a product serves this population effectively. However, current commercial products for pediatric patients with partial hand limb absence do not satisfy all the needs of these patients; passive fingers are seen as being fragile and difficult to use while powered fingers are not indicated for use with the pediatric population. In this Fast Track effort, we propose to 1) internally verify the Point Mini through a battery of mechanical tests, 2) validate the user needs of the Point Mini for regulatory requirements by engaging pediatric subjects with partial hand limb loss and 3) assess the utility of the Point Mini through a clinical take-home study with pediatric patients who have partial hand limb loss. The mission of Point Designs is to innovate devices and algorithms in the field of upper limb prosthetic design. We develop products that provide prosthetists and patients with solutions to meet the unique needs of each patient in this dynamic and challenging healthcare setting. The Point Mini will provide an effective and durable solution for children with partial hand limb loss and ensure their ability to enjoy their childhood, family, and life to the fullest.

赛车小儿假肢使用高级手指 快速制造技术 抽象的 拟议项目的目的是开发和商业化纯机械，赛车小儿 假肢手指 - 点mini - 哪个1）具有行业领先的体力与体重比，2）可以操作 单侧（单手），3）在患者的掌pophangeal周围提供解剖旋转和屈曲 （MCP）关节和4）可以使用高级金属3D打印技术为每个患者定制。 部分手动缺勤的小儿患者需要采用高度个性化的方法。每个 儿童及其家人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个患者一起工作， 他们的家人使用任何组件和技术提供个性化的医疗解决方案 可用的。通常，该系统中的瓶颈是临床上合理的假肢组件的可用性 假肢者可以很容易地提出一个最佳的假肢系统，尤其是对于 小儿患者人群。 上肢损失最大的人群是那些缺席的部分手动。这个人口 超过所有其他上肢损失的人的数量超过10倍。因此，我们可以做出重要的 如果产品有效地为该人群服务，则临床影响。但是，当前用于小儿的商业产品 部分肢体缺席的患者无法满足这些患者的所有需求。看到被动的手指 由于没有指示小儿种群使用的动力，因此脆弱且难以使用。 在这项快速的努力中，我们建议1）内部通过一系列机械测试来验证点mini， 2）通过与部分的儿科受试者互动，验证该点迷你的用户需求 手肢体损失和3）通过对小儿患者进行临床带回家研究评估点mini的效用 有部分手四肢损失的人。 点设计的使命是在上肢假体设计领域的创新设备和算法。 我们开发了为假肢和患者提供解决方案的产品，以满足每种的独特需求 在这种动态和挑战医疗环境中的患者。点mini将提供有效耐用的 解决部分手四肢损失的儿童的解决方案，并确保他们享受童年，家庭和生活的能力 充分。
