Description

Knee joint postoperative recovery degree trainer

Technical Field

The utility model belongs to the technical field of joint training device technique and specifically relates to a knee joint postoperative recovery degree trainer.

Background

The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella, is the most complex joint of the human body, and belongs to the pulley joint. The synovial layer of the knee joint is the widest and most complex of the total body joint, attached to the articular facet periphery of each bone of the joint, covering all structures within the joint except the articular cartilage and meniscus. The joint capsule of the knee joint is thin and loose, is attached to the periphery of each joint surface, and is reinforced by ligaments around the joint capsule to increase the stability of the joint. The knee joint is the most complex joint in the human body and also the largest load bearing joint of the human body. When the age of a person is increased, bones are abraded and degenerated after being used for a long time, so that diseases are induced, the person usually walks a little far and cannot climb stairs, and the knee joints of the person who is engaged in heavy physical labor and violent bouncing sports for a long time are easily damaged, and main symptoms comprise synovitis, cruciate ligament tear, meniscus damage, cartilage damage and the like. The knee joint replacement is the most commonly used clinical treatment for knee joint diseases. In knee joint replacement surgery, the success of the surgery is the key of treatment, but the rehabilitation training after the surgery is also indispensable, so that the patient can actively participate in the rehabilitation training after the surgery to recover in a shorter time. The exercise of the joint mobility is very important in the rehabilitation training after the artificial knee joint replacement. At present, to postoperative patient's early knee joint activity degree rehabilitation training clinically, the most common method is sitting in the patient and is carrying out the exercise of knee joint bending function, and the patient is sitting and is utilizing the quadriceps femoris muscle to exert oneself and carry out the exercise of knee joint bending function, but, the patient exerts oneself because the pain can influence when leaning on self to exert oneself and bending exercise, can not rely on shank strength to accomplish whole predetermined exercise action, influences the rehabilitation and tempers the effect.

To sum up, this technical scheme provides a knee joint postoperative recovery degree trainer in order to solve the technical problem that the shank can't rely on self shank to exert oneself to accomplish the recovered exercise action because of painful.
