Upper limb rehabilitation robot with active-passive type two arms

Abstract

The invention discloses an upper limb rehabilitation robot with active-passive type two arms, and belongs to the field of rehabilitation training robots. The upper limb rehabilitation robot with the active-passive type two arms comprises an upper limb active training device, an upper limb passive training device, over beam arms and a pedestal. The upper limb active training device and the upper limb passive training device are fixed on the pedestal through the over beam arms; the upper limb active training device comprises an active shoulder joint abduction and adduction assembly, an active shoulder joint flexion and extension assembly, an active upper arm intorsion and extorsion assembly, an active elbow flexion and extension assembly, an active forearm intorsion and extorsion assembly, and an active wrist joint flexion and extension assembly; and the upper limb passive training device comprises a passive shoulder joint abduction and adduction assembly, a passive shoulder joint flexion and extension assembly, a passive upper arm intorsion and extorsion assembly, a passive elbow flexion and extension assembly, a passive forearm intorsion and extorsion assembly, and a passive wrist joint flexion and extension assembly. According to the invention, motions of a plurality of joints in a plurality of dimensions can be achieved, and the upper limb rehabilitation robot can help the patient to exercise according to his own wish.

Description

technical field [0001] The invention relates to the field of rehabilitation training robots, in particular to an active and passive dual-arm upper limb rehabilitation robot. Background technique [0002] With the rapid development of medical technology, stroke is no longer a life-threatening disease, but motor dysfunction such as hemiplegia caused by brain injury has brought a heavy burden to the patient's family and society. Correct and scientific rehabilitation training plays a very important role in the recovery and improvement of limb motor function. Neurorehabilitation treatment process is a hard work. At present, rehabilitation doctors mainly rely on one-on-one manual operation and subjective clinical experience to evaluate patients' limbs, which limits the improvement of rehabilitation level, and the combination of rehabilitation medicine and robotic technology improves It improves the efficiency of rehabilitation training and ensures the intensity of action training...

AI Technical Summary

Problems solved by technology

[0003] However, there are many deficiencies in the upper limb rehabilitation robots at home and abroad when they are used for the treatment and rehabilitation training of patients with upper limb motor dysfunction: (1) the motor function is single, and only supports a single joint or some joints; (2) it can only realize one One-dimensional or two-dimensional movement, can not realize the function of rehabilitation training well; (3) single-arm passive movement, can not move according to the patient's wishes, can not stimulate the patient's interest and enthusiasm for training, etc.
