Novel wrist rehabilitation robot

Abstract

The invention discloses a novel wrist rehabilitation robot. By adopting an in-plane swing arm type design, the mechanical structure of the wrist rehabilitation robot comprises six parts including a swing arm type palm clamping structure, a motor and transmission mechanism, a laser indication and evaluation mechanism, an arm binding and adjusting structure, an overall framework and upper computer software. During use, one upper arm of a subject can be fixed to an adjustable bracket, one wrist of the subject is fixed to an adjustable clamping mechanism, and a motor applies a rotation speed to aswing arm and carries out torque control to achieve multi-pattern rehabilitation training of the wrist; through motor control, an angle indication plate, a laser indicator and a strain gauge, the movement of the wrist is evaluated. The palm clamping mechanism can also carry out self-adaption adjustment according to the features of the hand of the subject, and the comfort during rehabilitation training is improved. The laser indicator can also achieve vertical adjustment according to the position of the angle indication plate, and display and marking of the movement features of the wrist are achieved. The wrist rehabilitation robot is low in production cost, convenient to operate, high in safety and reliability and wide in application prospect.

Description

technical field [0001] The invention relates to the field of medical rehabilitation equipment research, in particular to a novel arm-swing type wrist rehabilitation robot. Background technique [0002] In my country, cardiovascular and cerebrovascular diseases have always been a major threat to national health. Every year, the number of patients with movement disorders in limbs due to cardiovascular and cerebrovascular diseases remains high. great obstacle. Patients suffering from Parkinson's and stroke often have wrist motor dysfunction, and involuntary hand movements can greatly interfere with the patient's grasping movements. Wrist movement dysfunction can be recovered and treated through appropriate rehabilitation exercises. However, there is a shortage of professional wrist physiotherapy talents in China, the demand for rehabilitation of patients is huge, and labor costs are also increasing year by year.

Problems solved by technology

Patients suffering from Parkinson's and stroke often have wrist motor dysfunction, and involuntary hand movements can greatly interfere with the patient's grasping movements.

Wrist movement dysfunction can be recovered and treated through appropriate rehabilitation exercises. However, there is a shortage of professional wrist physiotherapy talents in China, the demand for rehabilitation of patients is huge, and labor costs are also increasing year by year. There is an urgent need to design a medical device that can perform rehabilitation training on patients' wrists.

[0003] At present, some rehabilitation robots for limbs have been proposed, mainly for the entire shoulder of the patient, or for the rehabilitation of the patient's palm grasp, but few professional rehabilitation evaluation and training integration functions for wrist movement

Some upper limb medical rehabilitation robots have the function of driving the patient's wrist, but most of them adopt the form of exoskeleton, which is complicated in structure and expensive, and cannot be used for home use, making it difficult for patients with only wrist motor dysfunction to carry out targeted rehabilitation exercise training
