A portable finger and wrist rehabilitation robot

Abstract

The invention provides a portable finger and wrist rehabilitation robot, which comprises a motion transmission part, a motion control part, a power supply part, a rotating rocker arm part, a terminalinterface part, a finger rehabilitation training part, a wrist rehabilitation training part, a housing and a human-computer interaction part. The robot has two working modes: a finger rehabilitation mode and a wrist rehabilitation mode, which are realized by the combination of an arm sheath and a palm sheath and matching the corresponding finger rehabilitation training part or the wrist rehabilitation training part; the robot has two working modes: a finger rehabilitation mode and a wrist rehabilitation mode. The robot of the invention has three rehabilitation modes: active rehabilitation, passive rehabilitation and resistive rehabilitation, and can be realized by setting corresponding instructions in the human-computer interaction part. The invention has the advantages of convenient operation, simple structure and convenient operation, and has wide popularization significance.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a portable finger-wrist rehabilitation robot. Background technique [0002] At present, the most effective recovery method for stroke patients or patients with limb injuries after surgery is rehabilitation training, and finger and wrist rehabilitation training is a very critical link in the rehabilitation of patients' limbs. [0003] At present, there are some finger and wrist rehabilitation mechanisms on the market. For example, the invention patent application with the application number CN201610319764.6 discloses an upper limb rehabilitation robot finger and wrist training device. The device includes a mounting base and a wrist rotation mechanism. and finger grasping and stretching movement mechanism, the wrist rotation movement mechanism is driven by the first servo motor through a two-stage reduction mechanism, wherein the first stage reduction mechanism is a gear reduction ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned patent has the following disadvantages: the rotation of the wrist and the joint flexion / extension of the fingers are realized by two servo motors, the structure is relatively complicated, and the most important wrist-ulnar deviation and wrist flexion-extension movements in finger-wrist rehabilitation training cannot be realized. ; And no force sensor is set, it is impossible to realize active training and resistance training based on torque in rehabilitation training
