Limb rehabilitation exoskeleton

Abstract

The invention discloses a limb rehabilitation exoskeleton. The limb rehabilitation exoskeleton includes a first supporting rod, a second supporting rod, a first guide wheel assembly and a second guidewheel assembly, wherein the second supporting rod and the first supporting rod are rotatably connected, the first guide wheel assembly is arranged at the end, deviating from the second supporting rod, of the first supporting rod; and the second guide wheel assembly is arranged at the end, deviating from the first supporting rod, of the second supporting rod. According to the technical scheme, a guiding role can be played when the exoskeleton is used for assisting the human body in rehabilitation, the exoskeleton fits the movement track of limbs, and the rehabilitation effect is improved.

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 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 time, which g...

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, resulting in unsatisfactory rehabilitation effect
