A spatial four-degree-of-freedom lower limb rehabilitation training device

Abstract

The invention discloses a spatial four-degree-of-freedom rehabilitation training device for lower limbs. The device mainly consists of an arc-shaped baseplate, a main arc-shaped guiding rail, a left main arc-shaped guiding rail, a right main arc-shaped guiding rail, an arc-shaped rack, an auxiliary arc-shaped guiding rail, a left auxiliary arc-shaped guiding rail, a right auxiliary arc-shaped guiding rail, a leg rehabilitation training mechanism, a square bottom shell, a six-dimensional force sensor, a second hinge base, a third hinge base, an electric ankle joint pushing rod, a middle shaft,a fisheye bearing, a driving bearing sliding base, a driven bearing sliding base, a gear motor, a gear, universal wheels, lifting legs, a chair, a controller, a left leg training mechanism, a right leg training mechanism and the like. Multifunctional, multi-posture and more comprehensive rehabilitation training of the lower limbs can be carried out, flexion and extension movement of the lower limbs in a vertical plane can be achieved, retraction and extension movement around the hip joints of the human body is achieved, high rigidity can always be maintained, and movement stability is improved. The retraction and extension movement around the hip joints of the lower limbs of the human body is better in line with a movement law of the human body, and a better rehabilitation effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation equipment, and in particular relates to a lower limb rehabilitation training device with four degrees of freedom in space. Background technique [0002] At present, my country is entering an aging society, and the number of patients with cerebrovascular diseases, nervous system diseases, and lower limb motor dysfunction caused by accidents such as traffic accidents and sports disabilities among the elderly population is increasing year by year. In addition to early surgery and drug treatment for these patients, later rehabilitation training also plays an extremely important role in the recovery of lower limb motor function. As a kind of automatic rehabilitation medical equipment, the lower limb rehabilitation trainer provides great convenience for the rehabilitation of patients at various stages while reducing the workload of doctors.

AI Technical Summary

Problems solved by technology

[0003] There are many kinds of existing rehabilitation training devices, but most of them have a single degree of freedom of movement; or even if there are rehabilitation training devices that can achieve multiple degrees of freedom training, their structures are more complicated and the manufacturing cost is very high
