Abstract

The invention is a perception bionical mechanical hand and relates to a wounded finger rehabilitation device. It consists of either third knuckle module 1, framework 11 and first bionical muscle module 2 or second finger knuckle module 3, framework 11 and second bionical muscle module 4 or first finger knuckle module 5, framework 11, third bioncal muscle module 6 and fourth bionical muscle module 7 or bionical finger module 8 and bionical muscle module 9. The third knuckle module 1 links with the second knuckle module 3 which links with first knuckle module 5 in the bionical finger module 8 and third knuckle module 1 links with first bionical muscle module 2 while second knuckle module 3 links with second bionical muscle 4. First knuckle module 1 links with third bionical muscle module 6 and fourth bionical muscle module 7. The invention is of simple structure and fine safety and is able to cast rehabilitation treatment on single or multiple knuckles of the finger.

Description

Technical field: [0001] The invention relates to a wounded finger rehabilitation device, in particular to a sensory bionic manipulator used for clinical wounded finger rehabilitation. Background technique: [0002] The main function of the hand is accomplished through the flexible movement of the fingers, and the trauma that seriously affects the function of the fingers mainly includes: hand extensor and flexor tendon injuries, finger fractures, dislocations, corresponding nerve injuries that affect finger movements, finger separation injuries, finger injuries, etc. And palm soft tissue contusion. Clinically, it is often necessary to fix the affected finger in a functional position, a rest position, or a special position for 3 to 4 weeks after hand trauma surgery, resulting in stasis around the tendons in the joints and fibrosis, which leads to adhesion of finger joints and tendons, affecting The function of the affected finger. At present, the main methods for the treatme...
