Upper limb rehabilitation training robot

Abstract

The invention relates to an upper limb rehabilitation training robot which comprises a first joint, a second joint, a third joint, a fourth joint and a fifth joint; the five joints are sequentially connected serially; the movement of all the joints respectively corresponds to the unfolding / folding of shoulder joints, the bending / extension of the shoulder joints, the bending / extension of elbow joints, the internal rotation / external turning of forearms, the bending / extension of wrist joints and the bending / extension of fingers; all the joints of the robot are driven by independent motors; each joint is provided with a mechanical hard limit and an electric limit to protect the training of a patient; and the second joint and the fourth joint are respectively provided with a adjustment device capable of adjusting relative positions between the second joint and the third joint and between the third joint and the fifth joint. The upper limb rehabilitation training robot provides various rehabilitation movement for the turning of the shoulders, elbows and forearms as well as the wrist and finger joints of the upper limbs of the patient in a three-dimensional space, and can complete the upper limb rehabilitation training to the upper limbs of the patient with higher quality.

Description

technical field [0001] The invention relates to an upper limb rehabilitation training robot, which belongs to the technical field of medical rehabilitation training equipment. Background technique [0002] In recent years, the number of middle-aged and elderly patients with hemiplegia due to cerebrovascular disease or nervous system disease has been increasing, and the age is showing a younger trend; at the same time, the number of people with nerve damage or limb damage due to some accidents is also increasing , especially the loss of motor function of the upper limbs, has greatly affected the ability of daily life of patients. For these patients with hemiplegia and limb injuries, rehabilitation training is a very important and key medical method. [0003] With the progress of the research on the mechanism of modern central nervous system rehabilitation, researchers at home and abroad have carried out a lot of research on motor function rehabilitation based on robot technol...

AI Technical Summary

Problems solved by technology

[0004] At present, domestic and foreign upper limb rehabilitation training robots have many shortcomings and deficiencies when they are used for the treatment and rehabilitation training of patients with upper limb motor dysfunction. The movement of fingers and other joints is integrated into the system and device; the individual adaptability is poor, and the device cannot be adjusted according to different patients or it is inconvenient to adjust; the supported movement mode is single, and only passive movement can be performed or the device does not have a driving function; comfort Poor, can't better realize human-machine coordination and unity; can't stimulate patients' interest in training; can't better solve safety problems such as force and position overload
