An end-drawing finger rehabilitation robot

Abstract

The invention belongs to the field of rehabilitation medical equipment, and in particular relates to a terminal traction finger rehabilitation robot, comprising: a fixed seat, a power drive assembly and a finger flexion and extension mechanism; the power drive assembly includes: a torque sensor connected to a servo motor output shaft by a servo motor; The driving pulley assembly coaxially connected with the torque sensor, the encoder connected with the driving pulley assembly, the driven pulley assembly connected with the driving pulley assembly through the timing belt; the finger flexion and extension mechanism includes: electric push rod, fingerboard , set on the chute of the fingerboard, the thumb connector, the first thumb link, the second thumb link and the finger cot. The present invention drives four synchronous belts to move by a servo motor, and realizes the flexion and extension movement of the fingers through the limitation of the movement track by the chute on the fingerboard. The direction to move further ensures the safety of patients during rehabilitation training.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment, and in particular relates to an end-drawing finger rehabilitation robot. Background technique [0002] The hand is a fine "tool" for human life and social productive labor. Movement disorders in this part will seriously affect people's normal life. The best treatment for hand movement disorders is to repair damaged nerves and continuous passive rehabilitation training, but traditional one-to-one rehabilitation has problems such as large labor and high cost. With the development of science and technology, robot technology has been successfully introduced into the field of medical rehabilitation. In the field of rehabilitation robots, complex hand rehabilitation is one of the hotspots of research at home and abroad. It can control complex motion trajectories more precisely, and has the characteristics of low labor cost, high flexibility, simple operation and good curative ...
