Ankle rehabilitation mechanism based on human body association driving

Abstract

The invention relates to a flexible ankle rehabilitation mechanism based on human body self-driving and association motion. The mechanism comprises a base, a left foot fixator and a right foot fixator, the left foot fixator and the right foot fixator are arranged on the base, and rotation motion mechanisms are connected between the left foot fixator and the base as well as between the right foot fixator and the base; each rotation motion mechanism can rotate in the X, Y and Z axes, the two rotation motion mechanisms are connected through an association mechanism, an ankle which needs rehabilitation is driven through a healthy ankle, it is guaranteed that the same motion can be achieved at the left and right sides, the ankle which needs rehabilitation is driven through the healthy ankle ofa patient, and the action of the healthy ankle is completely reproduced. The patient can select different rehabilitation actions and action magnitude according to the self rehabilitation degree, thenflexible rehabilitation is achieved, and secondary harm does not exist; through a pure mechanical structure, the rehabilitation action of the ankle is effectively achieved so as to achieve the effectof helping rehabilitation of the patient, the mechanism is greatly simplified, and the mechanism is convenient to install and maintain and low in cost.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation machinery, in particular to a flexible ankle rehabilitation mechanism. Background technique [0002] With the development of science and technology and the improvement of medical level, people pay more and more attention to postoperative rehabilitation treatment, in order to restore the body to the greatest extent and maintain physical and mental functions, improve self-care ability and return to family or society smoothly. Therefore, how to more reasonably carry out the R&D and design of rehabilitation medical institutions with excellent recovery effects has become the focus of the field of medical machinery. [0003] Ankle rehabilitation is an important branch in the field of rehabilitation machinery. The ankle joint involves three degrees of freedom of extension and flexion, varus and varus, and internal and external rotation. At this stage, most of the ankle rehabilitation inst...

AI Technical Summary

Problems solved by technology

At this stage, most of the ankle rehabilitation institutions on the market are driven by motors combined with control algorithms to achieve ankle rehabilitation actions. The rehabilitation actions are single and lack flexibility, which is likely to cause secondary injuries to patients and cannot meet the different degrees of rehabilitation effects of patients; Rehabilitation effect to a certain extent will lead to overly complex algorithms and mechanisms, resulting in high cost
