Soft driver for assisting extension and abduction of thumb of human hand

Abstract

The invention discloses a soft driver for assisting extension and abduction of the thumb of a human hand and a pair of gloves. The soft driver comprises an inner-layer silicone tube, an outer-layer silicone tube, Kevlar fiber wires and two sections of fiberglass cloth, wherein the front end of the inner-layer silicone tube is sealed, and an opening is formed in the rear end and is used for connecting a pneumatic or hydraulic driving device; one Kevlar fiber wire is wound on the part, which corresponds to a metacarpal bone of the thumb, of the outer wall of the inner-layer silicone tube in a single-screw way, and the other Kevlar fiber wire is wound on the part, which corresponds to a phalanx of the thumb, of the outer wall of the inner-layer silicone tube in a double-screw way; the two sections of fiberglass cloth are both adhered to the side, which departs from fingers, of the inner-layer silicone tube, and positions of the two sections of fiberglass cloth respectively correspond to aconnecting joint of the metacarpal bone and a proximal phalanx of the thumb and a connecting joint of the proximal phalanx and a distal phalanx; the Kevlar fiber wires and the fiberglass cloth are fixed to the outer wall of the inner-layer silicone tube by the outer-layer silicone tube. By carrying the soft driver on the gloves, extension and abduction rehabilitation training of the thumb can beassisted.

Description

technical field [0001] The invention belongs to the field of hand joint assisted rehabilitation robots, and more specifically relates to a soft driver and a glove for assisting the stretching and abduction of the thumb of a human hand. Background technique [0002] Nowadays, the aging of the social population is increasing, and the number of people with hemiplegia caused by stroke and other diseases is increasing. At the same time, the number of people with impaired hand motor function caused by accidents such as production accidents and traffic accidents is also increasing year by year. These patients are often unable to take care of themselves due to hand motor dysfunction, which brings a lot of pressure to the family and society. The literature shows that the fingers of most patients are in a flexed state, and the muscles are stiff to varying degrees. This requires external force to assist the patient in stretching and opening the fingers. Traditional hand rehabilitation...

Problems solved by technology

[0004] In view of the above defects or improvement needs of the prior art, the present invention provides a soft actuator for assisting the extension and abduction of the thumb of the human hand. The phalanges and metacarpals of the thumb are stuck with glass fiber cloth to limit their degrees of freedom, so as to simulate the flexion, extension and abduction of the thumb, thereby solving the technical problem that the existing hand rehabilitation robot cannot assist the abduction of the thumb
