DESCRIPTION (provided by applicant): Among amputation types involving the upper limbs, partial hand is the most prevalent by far and among the most challenging for prosthetists to address well. Sound side overreliance for these amputees gives rise to a high prevalence of contralateral overuse syndrome (COS), a progressive, painful, and debilitating condition. Research shows that prostheses reduce the incidence of COS by encouraging more balanced, bimanual limb usage. Consequently, there is strong interest in developing new prosthetic options for partial hand amputees. At the same time, in certain developing countries the use of forced amputations to incite terror combined with deeply entrenched cultural stigmas have produced a growing population of amputees abroad who need functional and more realistic looking hand prostheses to help them reintegrate and regain social acceptance. Invisible Hand Enterprises, LLC (IHE) is developing a new articulated digit technology it believes holds the potential to help satisfy both of these overlapping needs by making possible the creation of affordable partial and whole hand prostheses having excellent cosmesis and grasp functionality. In Phase I of this three-phase Small Business Innovation Research (SBIR) program, IHE will complete the development of its digit technology and initiate field validation testing with volunteer subjects to assess whether commercial development is justified. IHE's digit system exploits properties and functional characteristics of synthetic textile fibers to replicate key functions of ligaments, tendons, and cartilaginous articulations within the anatomical finger, along with "bone" elements fabricated from engineering resin. This new prehensile digit technology is purposefully robust, lightweight, inexpensive, and achieves excellent adaptive grasp with strikingly lifelike movement. IHE will collaborate with Lake Prosthetics & Research, LLC (LPR) to refine its designs and maximize their clinical versatility, addressing frequently overlooked considerations such as means of attachment, adjustable positioning, and efficient cable routing. Prototype digits will be fabricated and incorporated into three (3) partial and three (3) whole hand prostheses. Volunteer subjects will wear these prostheses to assess the digits' performance under strenuous real-world operating conditions. Phase II comprises making design refinements to address issues invariably identified in Phase I, expanding testing to include more demanding tasks and environments, and establishing manufacturing infrastructure to support Phase III commercialization activities. IHE exists to create technologically and economically appropriate prosthetics options for disadvantaged amputees worldwide, enabling them to regain functionality, personal dignity, joy in living, and social, cultural, and tribal acceptance. The company's fundamental objective is to delight amputees by providing tools that help them relish living and enjoy an even higher quality of life. IHE asserts the work described in this submittal is important and worthwhile, and wholly consistent with the spirit and purposes of the National Institute of Health's (NIH) SBIR program. PUBLIC HEALTH RELEVANCE: Invisible Hand Enterprises' innovative new prehensile digit technology uses synthetic textile fibers to realize modular fingers that are robust, lightweight, and inexpensive. Designed for off-the-shelf use by the prosthetist, they are intended for both partial and whole hand prostheses, providing secure, stable grasp and realistic movement for excellent cosmesis. The technology purposefully addresses needs within the United States and in developing countries for technologically and economically appropriate options that help users participate and contribute to their families and society.

描述（由申请人提供）：在涉及上肢的截肢类型中，部分手是迄今为止最普遍的，也是假肢者最具挑战性解决方案的最具挑战性。这些截肢者的声音过度依赖会导致对侧过度使用综合征（COS）的高流行，这是一种进行性，痛苦和令人衰弱的状况。研究表明，假体通过鼓励更加平衡的双肢使用来减少COS的发生率。因此，有浓厚的兴趣对为部分手截肢者开发新的假肢选择。同时，在某些发展中国家，使用强制截肢来促进恐怖，并结合根深蒂固的文化污名，在国外产生了越来越多的amputees人群，他们需要功能和更现实的外观手工假肢来帮助他们重新融合并重新获得社会接受。 Invisible Handerprises，LLC（IHE）正在开发一种新的铰接数字技术，它认为具有通过使负担得起的局部和整个手工假体具有出色的化妆和掌握功能的可能性来帮助满足这两种重叠需求的潜力。在这项三相小型企业创新研究（SBIR）计划的第一阶段中，IHE将完成其数字技术的开发，并与志愿者受试者启动现场验证测试，以评估商业发展是否合理。 IHE的数字系统利用合成纺织纤维的特性和功能特性，以复制解剖手指内韧带，肌腱和软骨关键的关键功能，以及工程树脂制造的“骨头”元素。这项新的预性数字技术有目的地强大，轻巧，便宜，并且具有出色的适应性掌握，并具有惊人的栩栩如生的运动。 IHE将与Lake Prosthetics＆Research，LLC（LPR）合作，以完善其设计并最大化其临床多功能性，以解决经常被忽视的考虑因素，例如依恋方式，可调节定位和有效的电缆路由。原型数字将被制造并合并到三（3）个部分和三（3）个全手假体中。志愿者将佩戴这些假肢，以评估在剧烈的现实工作条件下的数字表现。第二阶段包括制作设计改进，以解决第一阶段中确定的问题，扩大测试以包括更苛刻的任务和环境，并建立制造基础设施以支持III阶段的商业化活动。它的存在是为在全球范围内为处境不利的截肢者创建技术和经济上适当的假肢选择，使他们能够恢复功能，个人尊严，生活乐趣以及社会，文化和部落的接受。该公司的基本目标是通过提供帮助他们享受生活并享受更高生活质量的工具来满意截肢者。他断言，本提交中描述的工作很重要且值得，并且完全符合美国国立卫生研究院（NIH）SBIR计划的精神和目的。 公共卫生相关性：无形的手工企业创新的新型智利数字技术使用合成的纺织纤维来实现强大，轻巧且价格便宜的模块化手指。它们专为假肢的现成使用，旨在用于部分和整个手工假体，提供安全，稳定的掌握和逼真的运动，以提供出色的化合物。该技术有目的地解决了美国境内以及发展中国家的需求，以帮助用户参与并为其家庭和社会做出贡献，以帮助用户参与并做出贡献。
