Abstract

The invention belongs to the technical field of rehabilitation medical devices, and particularly relates to a wrist rehabilitation robot with three degrees of freedom. The robot includes a fixation base, an inward / outward rotating mechanism, a palmar flexion / dorsiflexion mechanism, a draw-back and expand mechanism and a handle assembly. The inward / outward rotating mechanism includes a first motor,a gear shaft, a semicircle big gear and a small-arm support assembly. The palmar flexion / dorsiflexion mechanism includes a first connection rod frame, a second motor, a driving bevel gear, a driven bevel gear and a second connecting rod frame; the draw-back and expand mechanism includes a third motor, a driving pulley and a driven pulley; the handle assembly is fixedly installed on a rotating shaft of the driven pulley. The three degree-of-freedom wrist rehabilitation training can be achieved through a simple structure, the robot can be installed on a table for rehabilitation training, rehabilitation training of left and right hands can be achieved by the same machine, the cost is low and the robot is suitable for home use and popularization.

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...
