A stewart wearable wrist rehabilitation robot

Abstract

The invention discloses a Stewart type wearable wrist rehabilitation robot. The Stewart type wearable wrist rehabilitation robot comprises a front end motion platform, a training handle, six-dimensional force sensors, spherical hinge connecting devices, connecting rods, piston rods, cylinders, a rear end fixing and supporting platform and a control system. The front end motion platform can be driven through telescopic displacement of the piston rods. The Stewart type wearable wrist rehabilitation robot is used for rehabilitation therapy of postoperation of wrist joint diseases, postoperation of sports injuries and wrist postoperation, and bending and stretching motion, folding and unfolding motion and annular rotating motion of wrist joints can be achieved. The Stewart type wearable wrist rehabilitation robot has a passive working mode and an active working mode, and motion function rehabilitation and wrist strength training of the wrist joints can be achieved.

Description

technical field [0001] The invention relates to a novel wearable wrist rehabilitation therapy device, which belongs to the technical field of medical devices. Background technique [0002] The wrist joint is an important joint that connects the hand and the forearm. Because the hand often grabs objects frequently and engages in various operations, when the back is stretched suddenly, the palm of the hand falls, etc., it often causes wrist fractures and injuries. Wrist fracture treatment methods include conservative treatment and surgical treatment. Conservative treatment mainly adopts manual reduction, small splint or plaster external fixation. Surgical treatment mainly adopts surgical open reduction, parallel internal fixation such as plate. Surgical open reduction can do strong internal fixation. When the fracture is basically healed, active wrist flexion and extension exercises and wrist flexion and resistance exercises can be started. During the recovery period, pati...

AI Technical Summary

Problems solved by technology

At present, most of the human wrist joint rehabilitation therapy devices have a single function, which can only realize the recovery and exercise of some functions of the patient's wrist joint, and the drive control system is simple, which makes the wrist joint rehabilitation device less flexible and less practical.
