Pedal type lower limb rehabilitation training device

Abstract

The invention discloses a pedal type lower limb rehabilitation training device comprising two groups of pedal rotating mechanisms, a knee-hip joint moving mechanism and an ankle joint moving mechanism. Each pedal rotating mechanism comprises a pedal and a pedal shaft, wherein one end of the pedal shaft is connected with the pedal, the other end of the pedal shaft is connected with a leg-knee-hip joint moving mechanism and the ankle joint moving mechanism. The knee-hip joint moving mechanism comprises a central shaft, a transmission wheel and two connecting rods, wherein the two connecting rods are same in structure and connecting mode, and are symmetrically arranged relative to the central point of the central shaft. The ankle joint moving mechanism comprises a left sleeve, a right sleeve, an input transmission mechanism, a left transmission mechanism, a right transmission mechanism and two groups of output transmission mechanisms, wherein the transmission directions of the left transmission mechanism and the right transmission mechanism are opposite. The device realizes the transmission that a knee-hip joint and an ankle joint can move around the same central line, realizes the positive and passive rehabilitation training of six joints of a lower limb of a patient, has a compact structure, high space utilization, and accurate control, and is easy to realize modularization of the device.

Description

technical field [0001] The invention belongs to the field of rehabilitation medical equipment, and relates to a foot-operated lower limb rehabilitation training device, in particular to a foot-operated lower limb rehabilitation training device for patients with leg motor dysfunction caused by diseases, lower limb hemiplegia, various injuries, etc. device. Background technique [0002] With the development of society, the number of patients with limb movement disorders caused by population aging and various diseases and accidents is increasing. Patients with dysfunction or disabilities due to factors such as accidents, congenital defects, diseases, wars and body aging are in urgent need of effective treatment. medical rehabilitation. A large number of studies have found that rehabilitation training can promote the plasticity and functional reorganization of the central nervous system, restore or compensate the original function of the patient's limbs to the greatest extent, ...

AI Technical Summary

Problems solved by technology

[0003] In real life, there are many devices used for lower limb rehabilitation training, but most of them have complex structures, unreasonable use of space, low modularity, high manufacturing costs, and can only work in passive mode, that is, the devices drive the lower limbs of the human body to perform Movement, a small number of devices can work in active mode, that is, to restore to a certain extent the lower limbs of the human body actively perform movement

Even though some devices can realize active movement, but the degree of freedom is relatively small, and some important joint movements of patients cannot be effectively trained and corrected
