Problems solved by technology

However, the existing exoskeleton finger rehabilitation robot mechanisms are relatively large, and the method of separating the actuator and the driving mechanism is mostly used, which is not conducive to the realization of family rehabilitation.
In addition, the transmission structure of most exoskeleton finger rehabilitation robots is relatively complicated, which is not conducive to loading and unloading and achieves less degrees of freedom

Abstract

Disclosed is a TDOF external bone type finger rehabilitation robot. The TDOF external bone type finger rehabilitation robot is characterized by comprising a motor driving unit, a transmission unit and an execution unit. The working method of the TDOF external bone type finger rehabilitation robot comprises of motor driving force input, finger MCP (metacarpophalangeal) joint movement, finger PIP (proximal interphalangeal) joint movement, finger DIP (distal interphalangeal) joint movement and movement parameter adjustment. The TDOF external bone type finger rehabilitation robot has the advantages of being intelligent, portable, easy to mount and efficient in exercising method and controlling the rehabilitation movement of a patient through the movement of finger joints.

Description

(1) Technical field: [0001] The invention belongs to the field of robots, and in particular relates to a three-degree-of-freedom exoskeleton finger rehabilitation robot, which is especially suitable for finger motor function recovery training for hemiplegic patients caused by stroke (2) Background technology: [0002] Stroke, commonly known as stroke, has become the leading cause of adult disability in European and American countries. According to a 2007 survey report by the American Heart Association, there are more than 700,000 new stroke patients in the United States every year; in my country, according to incomplete statistics, the number of existing stroke patients is also more than 5 million. With the further intensification of population aging, the incidence of stroke will continue to increase in the next few years. Under normal circumstances, with the continuous improvement of medical treatment, about 60-75% of stroke patients can survive. However, most of them hav...
