Non-invasive knee joint stiffness function recovery device

Abstract

The invention discloses a non-invasive knee joint stiffness function recovery device including a seat, support units and a knee joint recovery unit. Two groups of support units are arranged, the kneejoint recovery unit is fixed on the support units by bolts; the knee joint recovery unit includes an electric telescopic rod, a guide rail, a movable block and a pedal plate; the guide rail is fixed on the support units; one end of the guide rail is fixedly connected with a rear fixed seat, the other end of the guide rail is connected with a front fixed seat through bolts; the electric telescopicrod is located in a guide rail groove in the guide rail; the fixed end of the electric telescopic rod is arranged on the rear fixed seat; the telescopic end is connected with a movable block. The invention provides the non-invasive knee joint stiffness function recovery device; the device has an assembled structure, and has the advantages of simple and convenient assembly and disassembly and low price, is suitable for household use, has no need for guidance by doctors, and has the functions of knee joint recovery and knee joint strengthening training.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a non-traumatic knee joint stiffness recovery device. Background technique [0002] When people play sports or have accidents, the incidence of fractures around the knee joint is relatively high. However, in the traditional treatment and operation of the knee joint and its surrounding area, the patient usually does not move for a long time, resulting in the joint being fixed in one position, which is possible. Cause joint or tissue internal and external adhesion, stiffness or contracture, leading to joint stiffness or deformity, etc., affecting the normal function of the joint, leaving sequelae, and bringing inconvenience to the work and life of the patient in the future. With the innovation and progress of medical technology, postoperative More and more attention has been paid to the rehabilitation of knee joint stiffness.

[0002] When people play sports or have accidents, the incidence of fractures around the knee joint is relatively high. However, in the traditional treatment and operation of the knee joint and its surrounding area, the patient usually does not move for a long time, resulting in the joint being fixed in one position, which is possible. Cause joint or tissue internal and external adhesion, stiffness or contracture, leading to joint stiffness or deformity, etc., affecting the normal function of the joint, leaving sequelae, and bringing inconvenience to the work and life of the patient in the future. With the innovation and progress of medical technology, postoperative More and more attention has been paid to the rehabilitation of knee joint stiffness. Usually, two methods are used to restore the function of knee joint stiffness: the first method is to treat by surgery, which can deal with some tissues of adhesion and contracture, and restore the knee joint to a certain extent. Joint function, but it is very likely to produce scars and re-adhesion consequences. If recovery exercises cannot be performed in time after the operation, it will also cause secondary stiffness, and the effect is not good. The second method is to use special instruments to make the joints continuously compare Long-term slow passive movement, through the metabolic process, causes the shortened soft tissue to undergo physiological changes and grow to adapt to the state of flexion. This method has a relatively good effect, but the medical devices in the prior art must go to specialized medical institutions Institutions, used under the guidance of doctors, have brought great trouble to patients and family members with limited mobility. Due to safety and price issues, it is difficult to realize home use. Usually, the device becomes useless after helping people restore the function of the knee joint. Strengthening knee joint function training requires additional money to purchase knee joint training equipment, which is more expensive, and the existing equipment is inconvenient to install and disassemble
