Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a three-point knee joint traction device. Background Art
[0002] Knee osteoarthritis often starts with the invasion of one side of the knee joint, more often on the inner side, affecting the blood perfusion of the intraosseous artery, resulting in insufficient oxygen supply, delayed secretion clearance, slowed metabolism, accelerated cartilage damage, and varus or valgus deformity, as well as tibiofemoral joint dislocation. Among them, varus is more common, which causes abnormal knee joint force line, which can increase the tension of the muscle-tendon complex around the joint. When the joint moves, the load increases and cannot be transmitted evenly, thereby aggravating cartilage damage and joint degeneration. Traction is a commonly used clinical treatment for knee osteoarthritis. It mainly uses the creep principle of biological tissue to expand the joint space, correct the force line of the lower limbs, reduce the intra-articular pressure, thereby improving the intraosseous venous return, reducing the intraosseous pressure and improving symptoms. Force line correction can relieve the tension of the muscle-tendon complex around the joint, increase the range of motion of the joint, thereby reducing the joint load, and to a certain extent restore the joint stress balance, increase exercise efficiency, and improve function. At present, the knee traction used in clinical practice is mostly axial traction of the lower limb skin. During use, it was found that for patients who have already been found to have valgus and varus of the knee, traditional axial traction cannot restore the changed lower limb force line, and it also does not pay attention to the point of traction. Although the symptoms and signs are improved, the correction of valgus and varus deformity and lower limb force line is not obvious. Utility Model Content
