Limb Rehabilitation Exoskeleton and Limb Rehabilitation System

Abstract

The invention discloses a limb rehabilitation exoskeleton and a limb rehabilitation system. The limb rehabilitation exoskeleton includes: a first support rod; a second support rod, which is rotatably connected to the first support rod; a first guide wheel assembly, and the first guide wheel assembly is arranged on the first support rod away from the second support rod The end of the second guide wheel assembly, the second guide wheel assembly is located at the end of the second support rod away from the first support rod, and its axis is perpendicular to the axis of the second support rod; and the limit structure, the limit structure It is arranged at the end of the first support bar away from the second support bar, and controls the first guide wheel assembly to rotate in one direction in the direction close to the second guide wheel assembly. The technical solution of the present invention can play a guiding role when the exoskeleton is used to assist the human body in rehabilitation, and fit the movement trajectory of the limbs, and the movement is stable, which improves the rehabilitation effect, and at the same time ensures the alignment of the joints and the firmness of the soles of the feet, increasing the human body feeling , which in turn is beneficial to the recovery of human nerves.

Description

technical field [0001] The invention relates to the technical field of exoskeletons, in particular to a limb rehabilitation exoskeleton and a limb rehabilitation system. Background technique [0002] In clinical rehabilitation, in the early and acute stages of rehabilitation of stroke, cerebral palsy and other patients, it is often necessary to awaken and reshape the brain nervous system interrupted and disordered by brain tissue damage through joint activities. Muscle atrophy, pressure sores on the limbs and other conditions. [0003] In the clinical rehabilitation department in the related art, most of the rehabilitation teachers artificially help patients to perform corresponding rehabilitation actions. Because the patient cannot provide the active power for movement during the flaccid paralysis period, at this time, it is completely necessary to rely on the rehabilitator to help the patient in training, which greatly wastes manpower and time costs. Due to the limited a...

AI Technical Summary

Problems solved by technology

Because the active force of exercise cannot be provided during the patient's flaccid paralysis period, it is completely necessary to rely on the rehabilitation teacher to help the patient with training at this time, which greatly wastes manpower and time costs

Due to the limited amount of rehabilitation for each rehabilitation teacher per day, it cannot meet the rapidly growing needs of patients with brain tissue injuries and orthopedic injuries

Moreover, through artificial rehabilitation training in the acute phase, the rehabilitation mode cannot be well controlled, such as effective switching between passive, active, and impedance modes, or, in rehabilitation training in related technologies, some machines are used to assist in guiding rehabilitation. However, the motion trajectory of the auxiliary machinery in the related technology is not smooth enough, and there is a large error with the motion trajectory of the limbs, which leads to unsatisfactory rehabilitation effects, and it is easy to have joint misalignment and inaccurate footsteps during rehabilitation training. , which is not conducive to the recovery of the patient's nerves
