Upper limb rehabilitation training robot

Abstract

The invention discloses an upper limb rehabilitation training robot. The upper limb rehabilitation training robot comprises a pedestal, an ergonomic seat, a rehabilitation mechanical arm and a man-machine interaction control cabinet, wherein the pedestal is provided with a height adjusting mechanism and a transversing mechanism; the transversing mechanism is provided with a suspending arm; the rehabilitation mechanical arm comprises a shoulder abduction / adduction joint, a shoulder bending / stretching joint, an upper arm, an elbow joint, a front arm inward turning / outward turning joint, a front arm, a wrist bending / stretching joint, a palm and fingers, wherein the shoulder abduction / adduction joint is arranged on the suspending arm; the shoulder bending / stretching joint is connected with the shoulder abduction / adduction joint; the front arm is connected with the upper arm by the elbow joint and provided with the front arm inward turning / outward turning joint; the palm is connected with the front arm by the wrist bending / stretching joint and connected with the fingers by a connecting rod; the upper arm, the front arm and the palm are fixedly connected with three force sensors; and the sensor fixedly connected to the upper arm is a two-dimensional sensor. The robot provides composite rehabilitation motion for each joint of the upper limb of a patient in a three-dimensional space and can finish the rehabilitation training of the upper limb with high 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 . In particular, the loss of motor function in the upper extremities greatly affects the patient's ability to perform daily living. For these patients with hemiplegia and limb damage, 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 r...
