An exoskeleton for knee joint rehabilitation

Abstract

The invention provides a knee joint rehabilitation walking exoskeleton, which is composed of three parts: a first limb binding structure, a second limb binding structure and an elastic walking aid component; the first limb binding structure includes a first guard plate , a second guard board, a synchronous connection board and a binding assembly, the second limb binding structure includes a third guard board, a fourth guard board, a synchronous connection board and a binding assembly, and the lower end of the first limb binding structure It is hinged with the upper end of the second limb binding structure, and the elastic walking aids with adjustable stiffness can meet the different needs of users with different degrees of injury and different degrees of rehabilitation for the size of the external assistance of the knee joint when walking, and the structure is adjusted as a whole. It is convenient, has a low failure rate, and cancels the active power-assisted structure of traditional exoskeletons such as cylinders and motors, which is safer and lower in cost.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a knee joint rehabilitation exoskeleton. Background technique [0002] On the one hand, when we play basketball and other sports in our daily life, the phenomenon of knee joint damage occurs from time to time, and the overall number of people is large; In view of the decline of physical function, ligament elasticity and muscle strength in the elderly population, more attention should be paid to their exercise status and quality of life. Knee walkers can provide necessary external assistance and exercise for people with knee injuries during walking during the rehabilitation phase, and can also provide necessary external assistance for walking for the elderly population with reduced exercise ability. Its application market prospects and specific practicability Both have strong competitiveness. [0003] Traditional exoskeletons are roughly divided into active e...

AI Technical Summary

Problems solved by technology

[0003] Traditional exoskeletons are roughly divided into active exoskeletons and passive exoskeletons. Active exoskeletons mostly use external power components such as cylinders or motors to provide assistance. The complex structure leads to a high failure rate, and the danger is strong when a failure occurs; the passive exoskeleton uses energy storage elements such as springs to use the bending force of the knee joint of the human body to assist in assisting. For home users, it increases the purchase cost and the timeliness of use, and cannot meet the needs of different power levels with different degrees of rehabilitation, as well as the different needs of the elderly with different physical states for power levels.
