摘要

如今,随着科技的进步,人类正在寻找治疗各种疾病的方法。同时,肌肉骨骼损伤通常需要较长的治疗周期。因此,近年来,研究人员研究了一种具有康复应用的外骨骼,用于物理治疗任务。本研究设计了一种便携式二自由度手外骨骼,其机构为电缆和连接机构相结合,mcp11metacarpophalangal_掌骨和近端指骨之间的关节mcp11metacarpophalangal_关节通过连接机构运动;dip22近端指骨与中端指骨之间的远端指骨间关节和pip33中指骨与远端指骨之间的近端指骨间关节通过电缆机制运动,拇指考虑前旋运动。通过比较不同机构的优化结果,采用优化方法对连杆机构进行了设计。四杆机构是最佳选择,其最大误差为3.95度。

Optimum mechanism for rehabilitation of fingers
Nowadays, with the advancement of technology, humans are looking for ways to cure various diseases. Meanwhile, musculoskeletal injuries usually have a long treatment period. Therefore, in recent years, Researchers working one exoskeleton with rehabilitation application which conduct physiotherapy tasks. In current study, a portable two degree of freedom hand exoskeleton is designed which its mechanism is a combination of cable and link mechanism, MCP11Metacarpophalangeal_ joint between metacarpal and proximal phalanges_ joints move by link mechanism, DIP22Distal interphalangeal_ joint between proximal phalanges and middle phalanges_ and PIP33Proximal interphalangeal _ joint between middle phalanges and distal phalanges_ joints move by cable mechanism and Pronation movement is considered for thumb. Link mechanisms are designed by optimization method, by comparing the optimization results of different mechanisms. The 4-bar mechanism is the best choice which its maximum error equal to 3.95 degrees.
