Drafting brace for ankle joint contracture

Abstract

The invention discloses a drafting brace for ankle joint contracture. The drafting brace comprises a lower limb fixing web, a push rod mounting support block, a push rod mounting pin, a left electric push rod, a rear elastic joint connecting strap, a side-part elastic joint connecting strap, a foot support, a left foot sole push rod mounting block, a left foot sole push rod mounting pin, a left foot sole push rod mounting rotary joint, an ankle joint angle adjusting knob, a right foot sole push rod mounting rotary joint, a right foot sole push rod mounting pin, a right foot sole push rod mounting block, a right electric push rod, a lower limb fixing binding band, a push rod control panel, a 24V push rod power supply and an elastic joint connecting strap pin. According to the drafting brace for the ankle joint contracture, ligaments and muscle around the ankle joint can be drafted by automatically adjusting the ankle joint angle, and are locked at corresponding positions, so as to help a patient improve the range of motion of the ankle joint and treat the ankle joint contracture.

Description

technical field [0001] The invention relates to an ankle contracture stretching brace, which is a rehabilitation brace capable of automatically adjusting joint angles to treat ankle contracture, and belongs to the technical field of rehabilitation medical equipment. Background technique [0002] When the ankle muscles, ligaments, bones are injured or the central nervous system is injured, the ankle joint will often be contracted and deformed due to prolonged braking or disuse. In order to solve this problem, it is necessary to use traction and stretching of the ankle joint surrounding muscles and ligaments to restore ankle mobility. The commonly used rehabilitation medical method is stretching by oneself or with the help of a doctor for ankle stretching training, and rehabilitation training can also be performed with the assistance of medical equipment. [0003] Existing medical devices for ankle joint rehabilitation generally have two forms: mechanical and electrical. The...

Problems solved by technology

The mechanical type can fit the joints of the human body very well, but usually requires people to manually adjust the amount of joint activity. This work is usually done by doctors. Doctors need to constantly adjust the joint angle according to the recovery time of muscles and ligaments, so they cannot be used effectively in large quantities. ;Electrical type is often simple in structure and easy to operate, and cannot control the adjustment range well, and cannot protect the physiological structure of the ankle joint, and excessive stretching often causes damage to tendons and ligaments

[0004] In the current study, Zhang Bin and others from Henan College of Traditional Chinese Medicine invented an electro-hydraulic ankle joint correction board in the patent CN 203354852U. Curative effect, improve work efficiency, a control handle is installed on the two hydraulic telescopic rods of the correction plate, and the joint angle can be adjusted within 0-35° through the control handle, but the structure is too simple to fit well Human ankle joints may become loose during use; Li Qiuju of Jilin University and others invented an adjustable ankle joint rehabilitation brace in the patent CN 203425085 U, which consists of a calf fixer and a foot support. Structure There is a disc with a screw hole at the ankle joint, through which the set screw at the disc can be used to fix the joint calf fixer and the foot support to control a certain angle. The shape of the lower limbs is fixed on the bracket through the fixing belt, but the rehabilitation brace needs to be manually adjusted by the doctor. The adjustment process is time-consuming, laborious and complicated

Based on the above current situation, there is no product that can automatically adjust the ankle joint rehabilitation brace and is suitable for actual medical treatment. This patent application is aimed at the needs of ankle joint rehabilitation, and designs a device that can automatically adjust the angle of the ankle joint to achieve stretching of the ligaments around the ankle joint. and muscles, to improve the rehabilitation brace of ankle joint contracture, which can automatically adjust the angle of ankle joint traction and stretching, and lock in the corresponding position to help patients improve the range of motion of ankle joint joints and treat ankle joint contracture
