Adjustable knee joint rehabilitation device with massage function

[0002] With the improvement of living standards, people pay more and more attention to their own health. Among them, the knee joint, as a high-incidence site of disease, has received more and more attention. Knee joint stiffness is due to the atrophy of knee joint structures such as synovium and cartilage. , degeneration and adhesion, resulting in the inability of the knee joint to bend or straighten freely, or severe pain during normal activities, which limits the function of the patient's knee joint and seriously affects the quality of life and work of the patient. There are two types of treatment methods for knee joint stiffness. One is surgical treatment, that is, directly loosens the adherent tissue through surgery, or directly prolongs the shortened part of the muscle bond and other tissues. The other is manual loosening and CPM machine. The principle of conservative treatment is to apply external force to the knee joint to slowly pull apart the adhesive tissue, and through the metabolism of the tissue, slowly lengthen the shortened tendon and other tissues, thereby improving the flexion function. However, surgical treatment is a Invasive treatment methods, re-operation will bring new trauma and pain to patients, and at the same time, scars and adhesions are still very likely to occur after surgical release, and conservative treatments such as manual release and CPM are still required after surgery, otherwise it will still cause secondary stiffness

[0003] Therefore, in this case, the knee joint rehabilitation device came into being. There are many kinds of rehabilitation devices after knee surgery, most of which are aimed at the knee joint and related muscle groups to perform corresponding knee joint bending exercises and knee joint straightening exercises. Knee joint rehabilitation training device is a special equipment for knee joint rehabilitation training in hospitals at present, and it is also an important means of postoperative rehabilitation. This passive rehabilitation training device is driven by a motor, and the two arms of its movement carry the patient's thigh and calf respectively. , when in use, the patient completely mounts the leg on the rehabilitation training device, and the motor drives the power arm to move, and the motion track simulates the bending action of the human leg, but the bending angle of the knee joint rehabilitation device cannot be adjusted. When the patient is training, due to the knee joint In the recovery stage, you will feel pain when bending at a certain angle. If you force the patient’s leg to perform large-scale bending movements, it will not be conducive to the recovery of the patient’s knee joint, and will also reduce the patient’s enthusiasm for training. Bending, atrophy, numbness, poor blood flow and other problems that may occur after the calf muscles are not stressed for a long time
