Seven-degree-of-freedom linkage multi-joint wearable rehabilitation mechanical glove

Abstract

The invention belongs to the field of medical rehabilitation machines, and particularly relates to a seven-degree-of-freedom linkage multi-joint wearable rehabilitation mechanical glove which comprises a palm mounting assembly, a thumb assembly, a four-finger assembly and a four-finger linkage transmission assembly. The thumb driving assembly is used for driving the thumb branch chain to achieve bending and stretching actions, the finger assembly comprises a finger branch chain and a finger driving assembly, and the finger driving assembly is used for driving the finger branch chain to achieve bending and stretching actions. And the four-finger linkage transmission assembly is used for synchronously driving the four finger branch chains to realize abduction and adduction actions. The invention has the characteristics of novel structure, small number of prime movers, light weight, small size, flexible movement and the like.

Description

technical field [0001] The invention belongs to the field of medical rehabilitation machines, and more specifically relates to a seven-degree-of-freedom linkage multi-joint wearable rehabilitation mechanical glove. Background technique [0002] Finger motor dysfunction is mainly caused by various accidents, brain injury, polio and other reasons. In finger rehabilitation training, according to the sequence of training stages, the training mode can be divided into passive training and active training. Passive training refers to that in the early stage of training, relying on the outside world to stimulate the damaged nerves with a large number of repetitive bending movements of the fingers, mainly the finger joints, to strengthen the strength of the finger muscles and the flexibility of the joints. This process requires the guidance and companionship of professional physiotherapists and physicians, which is time-consuming and labor-intensive. After this stage, the patient's ...

AI Technical Summary

Problems solved by technology

[0013] The present invention aims to solve the problem that the finger joint rehabilitation machine in the current market has a large structure, heavy weight, and is not easy to wear. Therefore, a seven-degree-of-freedom linkage multi-joint wearable rehabilitation mechanical glove is proposed, which can realize the abduction and adduction movement between four fingers and the bending and stretching movement of a single finger, reducing the need for motor startup. The external impact when stopping and moving, the number of prime movers is small, the weight is light, the size is small, and the movement is flexible, etc.
