Driving and driven hand rehabilitation training robot

Abstract

The invention provides a driving and driven hand rehabilitation training robot. The driving and driven hand rehabilitation training robot comprises a support frame and five finger driving modules; the five finger driving modules are a thumb driving unit fixed on the left side or the right side of the support frame and four four-finger driving units fixed on the support frame side by side; each of the five finger driving modules comprises a mounting bracket, a first motor, a second motor, a first driving bevel gear, an underframe large bevel gear, two gear connecting rods, a second transmission bevel gear, a third transmission bevel gear, a second driving bevel gear, a fourth transmission bevel gear, a fifth transmission bevel gear, an arc-shaped frame and a finger fixing assembly; the first transmission bevel gear is meshed with the second transmission bevel gear and the third transmission bevel gear; and the fifth transmission bevel gear is meshed with the second transmission bevel gear and the third transmission bevel gear. By starting the first motor and closing the second motor, buckling / stretching movement of the four fingers and the thumb is achieved, and adduction / abduction movement of a single finger is achieved through cooperative use of the two motors.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment, and in particular relates to an active and passive hand rehabilitation training robot. Background technique [0002] In life, more than half of stroke patients have residual limb dysfunction, and hand dysfunction accounts for more than 80%. With the development of robotic technology in the medical field, the use of high-end auxiliary equipment for hand rehabilitation training for patients has the characteristics of easy operation, high cost performance, diverse modes and good effects, and is highly valued by clinicians and favored by patients. As a high-end medical device, the finger rehabilitation robot is dedicated to solving the problem of inefficiency in traditional therapy. It can help patients carry out high-intensity, repetitive, targeted and interactive rehabilitation training, and promote the reconstruction of damaged functional areas of the brain. The motor fun...
