A hand rehabilitation training device

Abstract

The invention belongs to the technical field of medical equipment, and in particular relates to a hand rehabilitation training device, comprising three parts: a hand dorsal extension and palm flexion mechanism, a hand internal rotation and external rotation mechanism, and a hand radial flexion and ulnar flexion mechanism; The extension and palm flexion mechanism performs a limited-angle rotational motion on the horizontal plane to realize the training of two physiological movements of hand dorsiflexion and palm flexion; the hand internal rotation and external rotation mechanism performs a limited-angle rotational motion on the vertical plane to realize the internal rotation and external rotation of the hand. The training of two physiological movements of rotation; the hand radial flexion and ulnar flexion mechanism performs a pitching swing with a limited angle to realize the training of two physiological movements of hand radial flexion and ulnar flexion. The present invention can realize the rehabilitation training of the full degree of freedom of the hand joints, and enables the patient to perform the rehabilitation training in various comfortable postures at home.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a hand rehabilitation training device, which is suitable for patients with cerebrovascular disease, severe brain trauma and other nervous system diseases caused by hand dysfunction and recovery of upper limb function after surgery. Background technique [0002] The main movement form of the hand rehabilitation training device is active movement, that is, the hand drives the rehabilitation device to perform corresponding movement. The exercise content includes three motion modes: dorsiflexion and palmar flexion, internal rotation and external rotation, and radial and ulnar flexion. At present, most of the devices on the market can only achieve single-degree or two-degree-of-freedom hand movement, and cannot achieve all-round movement training with three degrees of freedom of the hand. Rehabilitation training leads to unsatisfactory results of patients' rehabilitation an...

AI Technical Summary

Problems solved by technology

At present, most of the equipment on the market can only realize single-degree-of-freedom or two-degree-of-freedom hand movement, and cannot realize all-round motion training of three-degree-of-freedom hands. This has great limitations and cannot meet the complete needs of patients. Rehabilitation training leads to unsatisfactory recovery effect of the patient and affects the confidence of the patient in recovery

In addition, the medical rehabilitation equipment on the market is basically oriented to hospitals and rehabilitation centers. The equipment is relatively large, and few of them are oriented to home users.
