Software driver for assisting four-finger stretching of human hand

Abstract

The invention discloses a software driver for assisting four-finger stretching of a human hand. The software driver includes an inner layer silicone tube, an outer layer silicone tube, a Kevlar fiberline and three-section glass fiber cloths. The front end of the inner layer silicone tube is closed, the rear end of the inner layer silicone tube is provided with an opening which is used for being connected with an air pressure or hydraulic driving device, the Kevlar fiber line is wound around a portion of the outer wall of the inner layer silicone tube corresponding to four-finger phalanges ina double helix mode, the three-section glass fiber cloths are attached to the side of the inner layer silicone tube deviated from the fingers, the positions respectively correspond to a connecting joint for the four-finger phalanges and proximal phalanges, a connecting joint for the proximal phalanges and intermediate phalanges and a connecting joint for the intermediate phalanges and distal phalanges; the outer layer silicone tube sleeves the inner layer silicone tube and is closely combined with the inner layer silicone tube, and the Kevlar fiber line and the glass fiber cloths are fixed onthe outer wall of the inner layer silicone tube. By loading the drive, a glove achieves simulation of four-finger stretching exercise and assists the four fingers in stretching training.

Description

technical field [0001] The invention belongs to the field of hand exoskeleton rehabilitation robots, and more specifically relates to a software driver for assisting the stretching motion of four fingers 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 treatment most...

Problems solved by technology

[0007] In view of the above defects or improvement needs of the prior art, the present invention provides a soft actuator for assisting the stretching movement of the four fingers of the human hand. By using a silicone tube as the core structure of the soft actuator, a double helix is ​​wound with a Kevlar fiber wire. Wrap the phalanx of the silicone tube, and paste the glass fiber cloth to limit its degree 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
