Description

Correcting device for joint deformation treatment

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a correction device for joint deformation treatment.

Background

The artificial total knee arthroplasty aims to relieve joint pain, correct joint deformity and improve the functional state of the affected knee, thereby improving the daily life quality of patients after operation. The rehabilitation activities are carried out before and after the operation, so that the knee joint activity degree can be increased to the maximum extent, and the knee joint function of the prosthesis is improved. Treatment during the operative period and postoperative rehabilitation exercise will have a direct impact on the functional improvement of the postoperative knee joint. Attention should be paid to the operator and the patient should be fully aware. Comprehensive and adequate rehabilitation is important for the success of total knee replacement surgery.

The main purpose of postoperative rehabilitation exercise is to strengthen extensor muscle strength around knee joint, improve knee joint mobility, and promote physical strength and state recovery. Through active or passive activity exercise of the knee, the postoperative joint adhesion is prevented, the blood circulation of local or whole lower limbs is improved, and the occurrence of postoperative complications is reduced. Through walking or other coordination training, the balance coordination of the muscle force around the knee joint and the soft tissue is improved, and the stability of the joint is ensured. Through joint movement training, the movement degree and the function of the knee joint approach to those of a normal person, so that the knee joint can meet the requirements of daily life actions and participation in part of social activities. Meanwhile, the mental and psychological aspects of the patient can be improved, and healthy life enthusiasm is stimulated. However, since a part of patients who perform knee joint replacement have knee joint buckling deformity with different degrees after operation, and unbalanced muscle strength is caused, a certain influence is brought to the daily life of the patients, so that early rehabilitation is very important. At present, few rehabilitation instruments special for correcting the buckling deformity after the knee joint replacement operation are clinically used, parts of the instruments are complex in operation and high in use cost, and secondary injury can be caused to a patient during use.

Therefore, this proposal proposes an orthotic device for the treatment of joint deformity.
