Hand rehabilitation training device

Abstract

The invention belongs to the technical field of medical equipment, and particularly relates to a hand rehabilitation training device which comprises a hand dorsal extension and palmar flexion mechanism, a hand internal rotation and external rotation mechanism and a hand radial flexion and ulnar flexion mechanism. The hand dorsal extension and palmar flexion mechanism rotates at a limited angle on a horizontal plane, so that the training of two physiological actions of hand dorsal extension and palmar flexion is realized; the hand internal rotation and external rotation mechanism performs rotation movement at a limited angle on a vertical surface, so that two physiological actions of internal rotation and external rotation of the hand are trained; and the hand radial flexion and ulnar flexion mechanism performs pitching swing at a limited angle, so that training of two physiological actions of hand radial flexion and ulnar flexion is realized. According to the invention, full-degree-of-freedom rehabilitation training of hand joints can be realized, and a patient can perform rehabilitation training in various comfortable postures at home.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and particularly relates to a hand rehabilitation training device, which is suitable for patients with hand dysfunction caused by cerebrovascular disease, severe traumatic brain injury and other nervous system diseases and for recovering 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 movements. The movement content includes three movement modes of dorsiflexion, palmar flexion, internal rotation and external rotation, radial flexion and ulnar flexion. 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...
