Limb rehabilitation exoskeleton and limb rehabilitation system

Abstract

The invention discloses a limb rehabilitation exoskeleton and a limb rehabilitation system applying the same. The limb rehabilitation exoskeleton comprises a first supporting rod and a second supporting rod which are rotationally connected; a first guide wheel assembly is arranged at the end, deviating from the second supporting rod, of the first supporting rod, and a second guide wheel assembly is arranged at the end, deviating from the first supporting rod, of the second supporting rod; and when the first supporting rod rotates relative to the second supporting rod under the action of external force, the first guide wheel assembly and the second guide wheel assembly guide movement of the first supporting rod and the second supporting rod, and a first limiting piece limits rotation of thesecond supporting rod relative to the first supporting rod. The limb rehabilitation exoskeleton is more consistent with motion trails of limbs, and the rehabilitation effect is good; and in addition,the flexion-extension angle of the limbs is within a certain threshold value, that is, the situations of excessive bending and hyperextension of knees can be avoided, and thus the rehabilitation effect of a patient is ensured.

Description

technical field [0001] The invention relates to the technical field of exoskeleton, in particular to a limb rehabilitation exoskeleton and a limb rehabilitation system. 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 wi...

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

At the same time, in order to allow the thigh and calf to rotate freely, that is, the range of flexion and extension of the thigh and calf is wider, the relevant limb rehabilitation equipment is often not provided with a limit structure, so that the patient may have excessive knee bending or The risk of knee hyperextension, affecting the patient's rehabilitation effect
