背景:假肢接受腔是残端和假肢之间的连接部分,这是假体功能的重要基础。目前的假肢接受腔难以满足目前截肢者的需求,这是截肢者放弃假肢的主要原因。本文综述了下肢假肢接受腔的设计和使用。
方法:本出版物的贡献是回顾皮肤问题,假肢接受腔的界面应力和体积波动,这被认为是影响假肢接受腔使用的关键因素。此外,下肢假肢接受腔根据残端与假肢接受腔的接触类型不同,分为全接触型和框架型。并从不同的角度分析了它们的优缺点。
结论:旨在设计具有功能转移的假肢接受腔,插座的悬挂稳定性和舒适性,提出了一种实时自适应假肢接受腔的设计思想。它可以通过具有特殊机械性能的智能材料来实现。
BACKGROUND: The prosthetic socket is the connecting part between the stump and the prosthesis, which is the important basis for the function of the prosthesis. The current prosthetic socket is difficult in meeting the needs of amputees current, which is the main reason for amputees abandoning their prostheses. This paper reviews the design and use of prosthetic sockets for lower limb.
METHODS: The contribution of this publication is to
review the skin problem, interface stress and volume fluctuations for prosthetic sockets, which are proposed as the key factors affecting the use of prosthetic sockets. Moreover, the lower limb prosthetic sockets are classified into the full-contact and the frame-type sockets according to the different contact type between stump and prosthetic socket, and their advantages and disadvantages are analyzed from different perspectives.
CONCLUSIONS: Aim to design the prosthetic socket with function transfer, suspension stability and comfort of socket, a design concept for prosthetic socket with self-adapt in real-time is proposed. It can be achieved by the smart materials with special mechanical properties.
