ABLE Kids II - Advanced Biofidelic Lower Extremity Kids Prosthesis II

描述（由申请人提供）：先进的生物相容性儿童下肢假肢（ABLE Kids）项目将通过推进已证明成功的I期器械并将其改进为适用于儿科使用的超紧凑和轻质外形，来推进最先进的儿科假肢系统。通过犹他湖城盐湖和洛杉矶什里夫波特的施里纳医院、众多假肢专家的支持，以及克拉克森大学尖端研究人员的咨询，将生产一种高度适应性的设备，并将其商业化，适用于患有创伤和先天缺陷的儿童截肢者。具体来说，ABLE Kids将产生一种模块化的、微处理器控制的、中间流体的踝关节，该踝关节动态地进行踝关节控制调整，以优化儿童假体的动态功能和安全性。此外，将开发先进的算法，通过调整地面反作用力优化经股动脉儿科受试者膝关节的触发点和释放，从而优化非微处理器控制膝关节的性能。 公共卫生相关性：该项目将推进儿童下肢假肢的最新技术水平。将采用新型的介观流体技术和控制算法，研制微型化微处理器控制的液压踝关节系统。其结果将是改善功能和减少问题的儿童肢体损失。

DESCRIPTION (provided by applicant): The Advanced Biofidelic Lower Extremity Kids prosthesis (ABLE Kids) project will advance the state-of-the-art of pediatric prosthesis systems by advancing the demonstrably successful Phase I device and refining it into an ultracompact and lightweight form factor suitable for pediatric use. Through the support of the Shriner's Hospitals in Salt Lake City, UT and Shreveport, LA, numerous prosthetists, and with the consultation of cutting edge researchers at Clarkson University, a highly adaptive device will be produced and commercialized suitable for childhood amputees with both traumatic and congenitial deficiencies. Specifically, ABLE Kids will result in a modular, microprocessor controlled, mesofluidic ankle joint that dynamically makes ankle control adjustments needed to optimize the dynamic function and safety of a child's prosthesis. Additionally, advanced algorithms will be developed to optimize the performance of non microprocessor controlled knees by adjusting ground reaction forces to optimize trigger point and release for knees in transfemoral pediatric subjects. PUBLIC HEALTH RELEVANCE: This project will advance the state of the art for lower limb prostheses for children. Novel mesofluidic technology and control algorithms will be used to make miniaturized microprocessor controlled hydraulic ankle joint system. The result will be improved function and decreased problems for children with limb loss.
