Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training, in particular to a rehabilitation training device for adhesion after knee joint surgery. Background Art

[0002] At present, the proportion of patients with orthopedic knee injuries (patella, tibial plateau, distal femur fractures, meniscus injuries, PCL / ACL injuries, internal and external collateral ligament injuries, etc.) is very high. Due to immobilization and lack of professional rehabilitation guidance in the early postoperative period, most patients are placed in the straight position, resulting in varying degrees of adhesion in the knee joint.

[0003] The knee joint is the largest synovial joint in the human body. It often causes adhesion due to braking, leading to dysfunction of the knee flexion and extension, which in turn causes abnormal gait, limping, and squatting difficulties, seriously affecting the patient's daily life.

[0004] Currently, when adhesions occur in the knee joints of patients, they will go to the rehabilitation department for professional training. For such patients, knee mobilization and knee stretching are generally performed to increase the elasticity of the knee capsule and thus increase the flexion and extension angles of the knee joint. During one treatment, a series of training, including stretching and loosening, activation, strength training, stability training, gait training, etc., is required. However, the time for each treatment is limited, so the patient's knee joint is not fully stretched during each treatment, resulting in obvious pain during the downward angle process, poor treatment effect, and also prolonged treatment cycle. In addition, the current stretching of the patient's knee joint is generally performed by hand, and the stretching time is 20 to 30 minutes, and the workload of medical staff is relatively high. Utility Model Content

[0005] The purpose of the utility model is to address the defects of the prior art and to provide a rehabilitation training device for postoperative adhesion of the knee joint, which can have a lasting stretching force on the knee joint and the force stretching the knee joint is always parallel to the tibia and fibula, effectively stretching the joint capsule, and the stretching force can be individually adjusted according to the patient's tolerance, and the stretching time can also be individually customized; the device can save the doctor's time and physical strength, and more time can be used to train the patient's overall function.
