Eight-degree-of-freedom upper limb rehabilitation training arms and device

Abstract

The invention belongs to the technical field of rehabilitation medical equipment, and particularly relates to eight-degree-of-freedom upper limb rehabilitation training arms and device. Each trainingarm comprises a shoulder blade movement assembly, a shoulder joint assembly, an elbow joint assembly, a wrist joint assembly, a big arm assembly and a forearm assembly; the shoulder blade movement assembly comprises a shoulder blade first support, a shoulder ascending and descending motor, a shoulder ascending and descending support and a shoulder forward stretching and backward moving motor; andone end of a sternoclavicular joint clavicle connecting rod is fixedly connected to an output shaft of the shoulder forward stretching and backward moving motor, and the other end is connected to theshoulder joint assembly. The training device comprises a lifting mechanism and a two-arm distance adjusting mechanism arranged at the output end of the lifting mechanism, and the two upper limb rehabilitation training arms are symmetrically installed on the two-arm distance adjusting mechanism. The training device can help a patient to perform comprehensive rehabilitation training on shoulder blades, shoulders, elbows and wrist joints, can help the patient to complete forward stretching / backward moving and ascending / descending actions of the shoulders, performs more thorough and comprehensiverehabilitation training on the upper limbs of the patient, and improves the training efficiency.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment, and in particular relates to an eight-degree-of-freedom upper limb rehabilitation training arm and a device. Background technique [0002] The upper limb rehabilitation training device is used to cooperate with or replace traditional rehabilitation therapists to carry out rehabilitation training for patients. Since rehabilitation training is mainly cyclic and repetitive movements, the rehabilitation training device has a long sustainability, making rehabilitation training more effective. [0003] Upper limb rehabilitation robots can be divided into two categories, one is terminal traction rehabilitation robot system, and the other is exoskeleton rehabilitation robot system. The terminal traction rehabilitation robot system is a mechanical system that drives the patient's upper limbs to move through the robot movement to achieve the purpose of rehabilitation training. The ...
