Limb rehabilitation exoskeleton and limb rehabilitation system

Abstract

The invention discloses a limb rehabilitation exoskeleton and a limb rehabilitation system applying the limb rehabilitation skeleton. The limb rehabilitation exoskeleton comprises a first supporting rod and a second supporting rod which are rotatably connected. A first guide wheel assembly is arranged at the end, deviating from the second supporting rod, of the first supporting rod, a second guidewheel assembly is arranged at the end, deviating from the first supporting rod, of the second supporting rod, a transmission assembly is connected with the first supporting assembly and the second supporting assembly, a power device is arranged at the end, away from the second supporting rod, of the first supporting rod, and the power device is connected with the transmission assembly. Accordingto 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. Meanwhile, the position of the power device is almost unchanged in the use process, and thus the power device is prevented from doing work by overcoming own gravity, the energyconsumption is reduced, and the problems of leg rotation and joint misalignment caused by the uneven distribution of gravity are solved, and thus the rehabilitation effect is further improved.

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 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 w...

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, and there is a large error with the trajectory of the limbs, resulting in unsatisfactory rehabilitation effects
