Rehabilitation training device for generalized shoulder joints

Abstract

The invention discloses a rehabilitation training device for generalized shoulder joints, and relates to the technical field of rehabilitation medical treatment equipment. The rehabilitation trainingdevice comprises an adjusting bracket, a shoulder blade belt motion assembly and a ball-and-socket joint motion assembly, wherein the adjusting bracket comprises a lifting column, an angle-adjusting support plate, an angle-adjusting motor, a slide rail support plate, a linear sliding rail and a flange type sliding block; the shoulder blade belt motion assembly comprises a first motor and a secondmotor; central lines of output shafts of the first motor and the second motor are converged at a point; the ball-and-socket joint motion assembly comprises a third motor, a fourth motor, a fifth motor, an upper arm machine frame, a fixed plate, a six-axis-force sensor and an upper arm support frame; and central lines of output shafts of a third motor, a fourth motor and a fifth motor are convergedat a point. Coordinated with the shoulder blade belt motion assembly arranged on a human body physiological structure, the device has six degrees of freedom, so that motions of bending / stretching, outreaching / inward-retracting and internal rotation / external rotation of the shoulder joints as well as motions of ascending / descending and forward heading / backward movement of ball-and-socket joints can be realized.

Description

technical field [0001] The invention relates to the technical field of rehabilitation medical equipment, in particular to a generalized shoulder joint rehabilitation training device. Background technique [0002] The latest statistics show that there are 70 million stroke patients in my country, 2 million new strokes every year, 1.65 million stroke deaths every year, and about 75% of the survivors are disabled and lose their ability to move their limbs. In 2017, the number of people over the age of 60 in my country has exceeded 230 million, and the increasingly serious population aging will lead to an increase in the number of physically disabled people. For patients with stroke, stroke and paraplegia, the quality of life depends on the degree of recovery of the function of the disabled limbs. It has always been the goal of rehabilitation workers to use advanced rehabilitation technology to improve the motor function of patients' limbs, so that patients can achieve the most...

AI Technical Summary

Problems solved by technology

[0005] At present, the existing upper limb rehabilitation robots generally only have 3 degrees of freedom or less at the shoulder joint. The existing problems are as follows: (1) Assuming that the center of the human shoulder joint is a fixed point, the movement of the scapula belt is ignored, which is different from the actual shoulder joint. The movement does not match; (2) the movement of the human-machine joint is incompatible, which is likely to cause secondary injury; (3) the range of motion of the shoulder joint is small, which cannot reach the normal range of motion of the shoulder joint
