limb rehabilitation exoskeleton

Abstract

The invention discloses an exoskeleton for limb rehabilitation. The exoskeleton for limb rehabilitation comprises: a first support rod; a second support 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 The end away from the second support bar; the second guide wheel assembly, the second guide wheel assembly is located at the end of the second support bar away from the first support bar; and a positioning structure, the positioning structure includes a first member, a second member and The connecting plate is fixed to the second support rod, the connecting plate and / or the second support rod is formed with a chute, the second member is slidably arranged in the chute, and the second guide wheel assembly is rotatably arranged in the second member The first member is arranged on the side of the second member away from the sliding groove at the end away from the connecting plate, and elastically abuts against the second member. The technical solution of the present invention can play a guiding role when the exoskeleton is used to assist human body rehabilitation, and fit the movement track of the limbs, improve the rehabilitation effect, reduce noise, and improve user experience.

Description

technical field [0001] The invention relates to the technical field of exoskeleton, in particular to a limb rehabilitation exoskeleton. Background technique [0002] In rehabilitation clinics, in the early and acute stages of rehabilitation for patients with stroke and cerebral palsy, it is often necessary to wake up and reshape the brain nervous system interrupted and disordered by brain tissue damage through joint activities. At the same time, joint activities can also be used to improve muscle strength and avoid Muscle atrophy, pressure sores on extremities, and other conditions. [0003] In the existing clinical rehabilitation departments, most of the rehabilitation teachers artificially help patients perform corresponding rehabilitation actions. Because the active force of movement cannot be provided during the patient's flaccid paralysis period, it is completely necessary to rely on the rehabilitation practitioner to help the patient with training at this time, which ...

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 the existing rehabilitation training, some machines are used to assist the rehabilitation. The trajectory of some auxiliary machinery is not smooth enough, there is a large error with the trajectory of the limbs, and the movement is not stable enough, resulting in unsatisfactory rehabilitation effects. However, when it is suitable for user rehabilitation, exoskeletons for limb rehabilitation are prone to noise. , reducing the user experience
