Abstract

The invention relates to an elbow and knee joint contracture deformity correcting device. The elbow and knee joint contracture deformity correcting device is mainly characterized by comprising an upper arc-shaped fixed plate (6), wherein the upper arc-shaped fixed plate (6) is arranged on a fixed bracket rod (9); the fixed bracket rod (9) comprises an upper fixed bracket rod (9-1) and a lower fixed bracket rod (9-2) and is hinged by a fixed bracket rod hinge (10); an upper arc-shaped fixed plate (6) is hinged with one side of a lower arc-shaped movable plate (8) and connected with the other side of the lower arc-shaped movable plate (8); pull rod seats (5) are arranged on the upper arc-shaped fixed plate (6) at both ends; a screw pitch regulator (1) is hinged with the pull rod seats (5) by movable pull rods (3); and positive and negative threads are respectively arranged on the left and the right movable pull rods (3).The elbow and knee joint contracture deformity correcting device meets the biological mechanical characteristics of the upper and the lower limbs of a human body by utilizing a Ilizarov biological theory, is fitted with the appearance contour, is comfortable for wearing, can be widely applied to a joint contracture orthopedic device in clinical, has the advantages of simple, stable and comfortable structure, reliable correcting strength, convenience in adjustment, safety, reliability and attractive appearance and has adjustable, stable, persistent and periodical tensile stress effect, and is used for carrying out four-dimensional phase correcting on the contracture tissue.

Description

technical field [0001] The present invention relates to a contracture deformity correction device. Background technique [0002] Due to trauma, burns, long-term immobilization, infection, and ischemic changes, muscle tissue necrosis, degeneration, contracture, and even severe degeneration of blood vessels, nerves, ligaments, and joint capsules, accompanied by severe scars and ulcers of the skin , malnutrition and skin and soft tissue defects. It can form skin contracture, connective tissue contracture, muscle contracture, neuropathic joint contracture and soft tissue contracture around the joint, resulting in obvious joint deformity and dysfunction. [0003] Elbow and knee joint contracture is the limitation of the range of motion of the joint caused by the tightening and shortening of the tissues inside and outside the joint or around it. It is common in various types of nerve paralysis after bone, joint and muscular system injuries and diseases, as well as long-term bed r...
