Push-rod underactuated finger rehabilitation training device

Abstract

The invention discloses a pusher underactuated finger rehabilitation training device which comprises a rehabilitation training mechanism I, a rehabilitation training mechanism II and a rehabilitationtraining mechanism III, wherein the rehabilitation training mechanism I aims to thumbs; the rehabilitation training mechanism II aims to middle fingers and forefingers; the rehabilitation training mechanism III aims to ring fingers and little fingers; each set of the rehabilitation training mechanism comprises a metacarpal support mechanism, a training mechanism and a driving mechanism; the metacarpal support mechanism of the rehabilitation training mechanism I is a support plate I; the metacarpal support mechanism of the rehabilitation training mechanism II is a support plate II; the metacarpal support mechanism of the rehabilitation training mechanism III is a support plate III; the support III and the support plate II are connected through a hinge; tail ends of the support plate I and the support plate II are connected through a four-freedom-degree passive joint; and middle parts of the support plate I and the support plate II through a thenar fitting plate. By adopting the device,weak finger actions of a patient suffering from hand hemiplegia can be acquired, intensions of the patient can be recognized, and the patient can be driven to carry out active rehabilitation trainingon the basis.

Description

technical field [0001] The invention relates to a push rod type underactuated finger rehabilitation training device, which belongs to the field of medical rehabilitation. Background technique [0002] The pathological changes of cerebral arterial and venous system caused by stroke will lead to the loss of motor function of limbs, and hand dysfunction is one of them. This kind of hand dysfunction often cannot be recovered at one time after surgery, and requires a long period of rehabilitation training in the later period, and studies have also shown that a lot of exercise can help the recovery of hand function. Traditional treatment methods rely on professional therapists to help patients recover through rehabilitation massage training. However, this treatment method has defects such as relying on the experience of doctors, limited treatment time and intensity, and inability to carry out active rehabilitation training. [0003] Exoskeleton training equipment can perform cert...
