Three-degree-of-freedom rehabilitation instrument for ankle joint injuries

Abstract

The invention belongs to the technical field of medical instruments and particularly relates to a three-degree-of-freedom rehabilitation instrument for ankle joint injuries. The instrument comprises abase and a single chip microcomputer, a first drive shaft and a first driven shaft which are parallel to each other are vertically arranged in the base, and a supporting shaft is installed at the upper end of the first driven shaft; a first stepping motor is installed on the portion, corresponding to the first drive shaft, on the base, an output shaft of the first stepping motor is in transmission connection with the first drive shaft, and a first drive gear is installed on the first drive shaft; a first driven gear is installed on the first driven shaft, a third stepping motor is installed on a motor fixing block, and a power output shaft of the third stepping motor is in transmission connection with the free end of a hinge rod; an n-shaped fixing plate is installed on the upper end faceof the base, bandages are arranged on a pedal and the n-shaped fixing plate respectively, and the single chip microcomputer is in electrical output connection with the first stepping motor, the second stepping motor and the third stepping motor separately. The three-degree-of-freedom rehabilitation instrument has the advantages that the ankle is driven to move from three angles, and the ankle joints are subjected to rehabilitation training.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a three-degree-of-freedom ankle joint injury rehabilitation device. Background technique [0002] Ankle joint injuries are relatively common in people's daily life. Ankle joint injuries may occur in sports activities and ordinary life. Ankle joint injuries not only bring pain to patients physically, but also seriously interfere with people's normal life. , more seriously even affect people's mental health. Most patients with ankle joint injuries need physical rehabilitation training during the medical treatment process to prevent muscle atrophy and restore ankle joint function. However, clinically, most of this kind of rehabilitation training relies on physical therapists to provide one-on-one physical therapy to patients, and the method is single and time-consuming and labor-intensive.
