Abstract

The invention relates to an isotropic ankle joint rehabilitation parallel connecting mechanism, which comprises a base, a movable platform and movement support chains, wherein a first support column and a second support column are respectively and fixedly arranged on the base, a first motor and a second motor are respectively arranged on the first support column and the second support column, a third motor is arranged on the base, the upper end surface of the movable platform is a pedal surface, a first telescopic rod and an L-shaped third telescopic rod are vertically and fixedly arranged at the upper end surface of the movable platform, a second telescopic rod is vertically and fixedly arranged at the lower end surface of the movable platform, the first motor is connected with the first telescopic rod on the movable platform through the first movement support chain to control the left and right swinging of the movable platform so as to realize the inward / outward turning movement of an ankle joint, and the second motor is connected with the second telescopic rod on the movable platform through the second movement support chain to control the front and back swinging of the movable platform so as to realize the extending movement of toes / back of the ankle joint.

Description

technical field [0001] The invention relates to the field of rehabilitation medical institutions, in particular to an isotropic ankle joint rehabilitation parallel mechanism for assisting ankle joint rehabilitation training. Background technique [0002] The ankle joint is one of the largest weight-bearing joints in the human body, and it is extremely prone to injury during daily walking, running, jumping and sports. If the injury is not treated in a timely and effective manner, it will not only affect the daily life of the patient, but also cause secondary injury to the ankle joint due to joint instability, which will seriously affect the normal walking function. The movement forms of the ankle joint are varus / valgus, toe / dorsiflexion, and internal / external rotation. The ankle joint is generally considered as a ball joint with three rotational degrees of freedom. Therefore, in order to comprehensively realize ankle joint rehabilitation training, the rehabilitation device ...
