Hand exoskeleton device for rehabilitation training

Abstract

The invention discloses a hand exoskeleton device for rehabilitation training. The hand exoskeleton device comprises an opisthenar mechanism, a power source, an index finger exoskeleton, a middle finger exoskeleton, a ring finger exoskeleton, a little finger exoskeleton and a thumb exoskeleton. The opisthenar mechanism comprises an opisthenar platform, a motor support and a screw support. The power source comprises an index finger part, a middle finger part, a ring finger part and a little finger part. The index finger exoskeleton, the middle finger exoskeleton, the ring finger exoskeleton and the little finger exoskeleton each comprise a connecting rod, a far knuckle support, a transition connecting rod, a middle knuckle support, a transmission connecting rod, a driving connecting rod and a near knuckle support. The thumb exoskeleton comprises a thumb driving rod, a thumb transmission rod, a thumb connecting rod, a thumb near knuckle support, a thumb far knuckle support, a thumb motor, a thumb screw rod, a thumb sliding block, a thumb screw rod support, a thumb sliding block connecting rod, a thumb motor support and a thumb back platform. The whole device is light, low in cost and easy to assemble, and solves the problems that in an existing hand rehabilitation device, all fingers are not independent from one another, the bending angle is limited, fine actions are difficult to achieve, and cost is high.

Description

technical field [0001] The invention relates to a human body motion auxiliary device, in particular to a hand exoskeleton device used for rehabilitation training. Background technique [0002] The most common type among people with neuromuscular system damage and disability is motor dysfunction, manifested as limb paralysis, which seriously affects the patient's self-care ability and quality of life, among which the loss of hand motor function is the most important. Considering the dexterity of hand function, hand function rehabilitation plays a vital role in improving the quality of life of patients; and because of this, hand function rehabilitation has always been a difficult problem in rehabilitation medicine. [0003] Rehabilitation medicine research and practice have shown that adhering to exercise rehabilitation training is an effective way to restore limb motor function. [0004] In traditional sports rehabilitation training, the clinical physiotherapist pulls the jo...

AI Technical Summary

Problems solved by technology

Currently, the structure of exoskeleton rehabilitation robots reported is relatively simple. Most of the large joints of the lower limbs or upper limbs are assisted in simple movements such as extension and flexion. A few exoskeleton devices for the hands provide limited degrees of freedom and complex structures, which are difficult to support. Each finger moves independently and cooperatively, and there is still a lot of room for improvement
