Flexible hand functional rehabilitation training device

Abstract

The invention relates to a flexible hand functional rehabilitation training device. The device comprises a double-shaft output speed reducer, a pair of first-stage synchronous belt drive mechanisms symmetrically arranged on the two sides of the speed reducer and in drive connection with the speed reducer, second-stage planet synchronous belt drive mechanisms in drive connection with the first-stage synchronous belt drive mechanisms, an adaptive adjusting bracket in drive connection with the second-stage planet synchronous belt drive mechanisms through gear sets, and finger flexible drive modules arranged on the adaptive adjusting bracket. Compared with the prior art, the overall structure is compact, the problems that hand rehabilitation of a stroke patient is difficult, and hand training can be carried out only by depending on professional doctors can be effectively solved, the current situation that existing hand rehabilitation equipment is poor in adaptability is broken through, left and right interchange can be achieved, rapid adjustment of the lengths of modules and the intervals between the modules is driven, and independent motion of thumb metacarpophalangeal joints, four-finger metacarpophalangeal joints and proximal interphalangeal joints under a lightweight structure can be achieved.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment, and relates to a flexible hand function rehabilitation training device, in particular to a flexible hand function rehabilitation training device applied to different situations of stroke patients. Background technique [0002] "Cerebral stroke", also known as "stroke" and "cerebral vascular accident" (cerebral vascular accident, CVA), is an acute cerebrovascular disease, which is caused by the sudden rupture of blood vessels in the brain or the inability of blood to flow into the brain due to vascular obstruction. A group of disorders that cause damage to brain tissue, including ischemic and hemorrhagic strokes. The incidence of ischemic stroke is higher than that of hemorrhagic stroke, accounting for 60% to 70% of the total stroke. Occlusion and stenosis of the internal carotid artery and vertebral artery can cause ischemic stroke, most of which are over 40 years old, m...

AI Technical Summary

Problems solved by technology

The technical solution disclosed in the above-mentioned patent can only be used for four-finger training, and the distance between each finger cannot be adjusted, and there is no instruction on the exchange of left and right hands. There is only one-stage transmission in terms of power transmission, which has limitations in terms of intelligence and somatosensory control.
