Lower limb rehabilitation exoskeleton

Abstract

The invention discloses a lower limb rehabilitation exoskeleton. The lower limb rehabilitation exoskeleton comprises a first supporting rod, a second supporting rod, a first guide wheel assembly, a second guide wheel assembly, an angle adjusting mechanism and an ankle fixing piece; the second supporting rod and the first supporting rod are rotationally connected, the first guide wheel assembly isarranged at the end, deviating from the second supporting rod, of the first supporting rod, the second guide wheel assembly is arranged at the end, deviating from the first supporting rod, of the second supporting rod, and the axis of the second guide wheel assembly is perpendicular to the axis of the second supporting rod; the angle adjusting mechanism is rotatably connected to the second guide wheel assembly, and the rotating axis of the angle adjusting mechanism is parallel to the axis of the second guide wheel assembly; and the ankle fixing piece is fixedly connected to the angle adjustingmechanism and rotates along with the angle adjusting mechanism. According to the technical scheme, the rehabilitation effect can be improved, and meanwhile the muscle force of surrounding muscles ofankle joints can be effectively improved.

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
