Exoskeleton-type elbow joint and shoulder joint rehabilitation instrument

Abstract

The invention provides an exoskeleton-type elbow joint and shoulder joint rehabilitation instrument which comprises a back support, a seat and two exoskeleton one-arm parts identical in structure. The seat is fixedly welded on the lower side of the back support, the one-arm parts are respectively mounted on two sides of the back support, two elbow joint traction hydraulic cylinders and two shoulder joint traction hydraulic cylinders are fixedly arranged on the inner side of the back support, traction movement of the hydraulic cylinders can draw steel wire ropes, and the steel wire ropes are drawn to draw exoskeleton elbow joints and shoulder joints to rotate; angle sensors are mounted at elbow joints, shoulder joints and knee joints of the rehabilitation instrument to measure angles at the joints, and a central control device controls movement of the traction hydraulic cylinders according to different measured angles. Hydraulic power assistance is adopted, so that movement of elbow joints and shoulder joints of upper limbs of a human body can be realized well, a patient can be assisted in activating basic functions of joints and arms, and the rehabilitation instrument is easy to wear, gentle and smooth in transmission, convenient to drive and good in movement effect.

Description

technical field [0001] The invention belongs to the research field of medical auxiliary therapy, and in particular relates to an exoskeleton type elbow joint and shoulder joint rehabilitation device. Background technique [0002] With the improvement of social living standards and the advancement of modern medical technology, the average life expectancy of our country continues to increase, and we are rapidly entering an aging society. As of 2010, the elderly population over 60 years old in my country has exceeded 178 million, accounting for 13.26% of the total population. Meanwhile, the elderly population over the age of 65 is about 119 million, accounting for 8.87% of the total population. On the other hand, with the acceleration of the pace of life and the increase of life pressure, stroke hemiplegia patients caused by cardiovascular and cerebrovascular diseases and nervous system diseases are increasing year by year. The incidence of stroke in my country is the highest...

Problems solved by technology

Traditional rehabilitation treatment mainly relies on rehabilitation physicians to perform manual rehabilitation training on patients, which has many limitations: (1) the training parameters cannot be precisely controlled, and the therapeutic effect mainly depends on the experience and level of physicians; (2) one-on-one treatment by physicians, rehabilitation Low training efficiency and high labor intensity for physicians

[0004] At present, the transmission system of rehabilitation equipment in society is mostly directly driven by motors. Although it can bring rehabilitation treatment to people, it has the disadvantages of high rigidity, poor flexibility, complex structure, and not easy to wear.
