[0002] After the elbow of an orthopedic patient undergoes surgery, the patient generally needs to stay in the hospital for a period of time. During the hospitalization of orthopedic patients, it is generally necessary to move the elbow of the orthopedic patient to accelerate the recovery speed of the elbow. Currently, it is generally the medical staff who hold the patient's hand and swing it up and down to move the elbow of the orthopedic patient. However, since the elbow of the orthopedic patient has just undergone surgery, the movement speed should not be too fast. Therefore, it takes a long time for the medical staff to achieve the purpose of accelerating the recovery speed of the elbow.
