Abstract

The invention belongs to the technical field of rehabilitation medical equipment, and in particular relates to a three-degree-of-freedom wrist rehabilitation robot, which includes a fixed seat, an internal rotation / external rotation mechanism, a palm flexion / dorsiflexion mechanism, an adduction / abduction mechanism and a handle assembly. The external rotation mechanism includes: the first motor, gear shaft, semicircular large gear and forearm support assembly; the palm flexion / dorsiflexion mechanism includes the first link frame, the second motor, the driving bevel gear, the moving The rod frame; the adduction / extension mechanism includes a third motor, a driving pulley and a driven pulley; the handle assembly is fixedly installed on the rotating shaft of the driven pulley. The invention can realize three-degree-of-freedom wrist rehabilitation training through a simple structure, can be installed on a desktop for rehabilitation training, and the same machine can realize rehabilitation training for left and right hands, and is low in cost, suitable for popularization and use at home.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment, and in particular relates to a three-degree-of-freedom wrist rehabilitation robot. Background technique [0002] Stroke has always been a major threat to national health, and among patients with hemiplegia caused by stroke, hand movement disorders account for a large proportion. For stroke patients with hand disabilities, the quality of life depends on The degree of recovery of hand function. Due to the characteristics of low labor cost, high flexibility, simple operation and good curative effect, hand function rehabilitation equipment is highly valued by clinicians and favored by patients. As a high-end medical device for neurorehabilitation, the intelligent hand function rehabilitation robot can help patients carry out high-intensity, repetitive, targeted and interactive rehabilitation training, promote the reconstruction of damaged functional areas of the brain, and i...
