A generalized shoulder joint rehabilitation training device

Abstract

The invention discloses a generalized shoulder joint rehabilitation training device, which relates to the technical field of rehabilitation medical equipment, and includes an adjustment frame, a scapula belt movement component and a ball and socket joint movement component; the adjustment frame includes a lifting column, an angle adjustment support plate, an angle adjustment motor, a slide Rail support plate, linear slide rail and flange type slider; the shoulder blade belt motion assembly includes a first motor and a second motor, and the centerlines of the output shafts of the first motor and the second motor meet at one point; the ball joint motion assembly Including the third motor, the fourth motor, the fifth motor, the upper arm frame, the fixed plate, the six-dimensional force sensor and the upper arm support frame; the center lines of the output shafts of the third motor, the fourth motor and the fifth motor meet at one point . The device has 6 degrees of freedom, coordinated with the shoulder girdle compound structure on the human body's physiological structure, and can realize shoulder joint flexion / extension, abduction / adduction, internal rotation / external rotation and ball-and-socket joint ascending / descending , Probe / retract movement.

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
