Abstract

Provided is a mechanical device used for rehabilitation of the injured ankle joint and the knee joint. Two ends of two support rods of a pedal located between two vertical plates of a support seat respectively stretch out through vertical holes of the two vertical plates and form a spatial sphere pair with lower ends of four spatial connecting rods, the upper ends of the spatial connecting rods and slide blocks form a spatial sphere pair, the four slide blocks can slide up and down along four guide rails fixed on the vertical plate, the pedal is fixedly connected with an elastic portion of a vertical annular flexible synchronous belt through a connecting rod, the upper end and the lower end of a tooth-shaped portion of the flexible synchronous belt are respectively engaged with an upper synchronous belt pulley and a lower synchronous belt pulley in a transmission manner, the axis of the upper synchronous belt pulley is arranged on a fixed shaft of the upper end of the vertical plate, and the axis of the lower synchronous belt pulley is arranged on an output shaft of a driven device formed by a torsion spring capable of adjusting the torque, a damper capable of adjusting the impedance, and a single-turn absolute value angle sensor. According to the device, the pedal can perform fine movement at six degrees of freedom in the space with the movement of the ankle joint and the kneejoint of a patient and adapt to the movement of the ankle joint and the knee joint, the pressure of rehabilitation training of the injured joint is alleviated, and the rehabilitation of the injured joint is promoted.

Description

technical field [0001] The present invention relates to medical devices, in particular to a mechanical device for rehabilitation of injured ankle joints and knee joints. Background technique [0002] When using some existing sports equipment for fitness, if the amount of exercise is too large, it will sometimes cause damage to the ankle joint or knee joint; in addition, some middle-aged and elderly people take brisk walking for fitness. Or the knee joint is also vulnerable to injury. For joint rehabilitation training for patients with ankle or knee injuries, it is necessary to reduce the pressure on the ankle or knee joints as much as possible during the training, so as to promote the rapid recovery of the injured joints. And be used for the rehabilitation training apparatus of this aspect at present and have not yet found. Contents of the invention [0003] The purpose of the present invention is to provide a mechanical device for the rehabilitation of injured ankle joi...
