Lower Limb Rehabilitation Exoskeleton

Abstract

The invention discloses a lower limb rehabilitation exoskeleton. The lower limb rehabilitation exoskeleton includes: a first support rod; a second support rod, the second support rod is rotatably connected with the first support rod; a first guide wheel assembly, the first guide wheel assembly is arranged on the first support rod away from the second support rod the end of the support rod; the second guide wheel assembly, the second guide wheel assembly is provided 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; an angle adjustment mechanism, the angle adjustment mechanism is rotatably connected to the second guide wheel assembly, and the rotation axis of the angle adjustment mechanism is parallel to the axis of the second guide wheel assembly; and an ankle fixing member, the The ankle fixing piece is fixedly connected to the angle adjustment mechanism and rotates following the angle adjustment mechanism. The technical scheme of the present invention can improve the rehabilitation effect; meanwhile, it can effectively improve the muscle strength of the muscles around the ankle joint.

Description

technical field [0001] The invention relates to the technical field of exoskeleton, in particular to a rehabilitation exoskeleton for lower limbs. 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 clinical rehabilitation departments in the related art, most 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 ti...

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 rehabilitation training in related technologies, some machines are used to assist in guiding rehabilitation. However, the trajectory of the auxiliary machinery in the related art is not smooth enough, and there is a large error with the trajectory of the limbs, resulting in unsatisfactory rehabilitation effects, and the ankle often only uses a fixed orthotic, which cannot effectively improve the muscles around the ankle joint. force
