一种生物力学腋拐的研究与设计

A novel design for biomechanical axillary crutches

目的针对以往腋拐存在的问题,设计一款结构简单、外形美观、科学合理的实用性腋拐。方法从人体生物力学、人机工程学、工业设计等方面出发,利用模块设计、柔性设计的方法对腋拐进行创新设计。结果经力学分析、有限元分析、样机质量检验、初步临床试用,验证了设计的可行性和临床适用性。结论本次新型腋拐的研究和设计具有极大的临床意义,其可有效减小使用者手腕和腋窝的受力,进而降低二次伤害的发生机率。同时,也可以为类似的拐杖设计提供参考。

Objective Try to design a novel axillary crutch with the feature of simple structure, nice appearance, and strong practicality, so as to overcome shortcomings for the past crutches. Methods Based on the methods of modular design and flexible design, an innovative design for axillary crutches was proposed from the aspect of human biomechanics, ergonomics, and industrial design as well. Results The feasibility and clinical applicability of the design were verified by mechanical analysis, finite element analysis, quality inspection of the prototype and preliminary clinical use. Conclusions The novel axillary crutch as the result of the research and design in this study is of great clinical significance. It can effectively reduce the force of wrist and axillary for users, and cut down the occurrence of the secondary damage. Also this study can provide a useful reference for design of other similar crutches.
