Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rehabilitation training equipment, in particular to a rehabilitation training device after hip and knee replacement surgery. Background Art
[0002] Hip and knee replacement is an effective means of treating joint diseases, especially for patients with severe osteoarthritis, rheumatoid arthritis and traumatic arthritis. Postoperative rehabilitation is one of the key factors that determine the success of surgery. Rapid and effective rehabilitation can not only relieve patients' pain and improve their quality of life, but also prevent postoperative complications. However, how to restore patients to normal joint function in a short period of time is still a major challenge in clinical practice. At present, most hospitals adopt different rehabilitation training methods and lack unified standards and specifications. Rehabilitation training in hospitals is usually guided by professional rehabilitation therapists, and patients can carry out effective rehabilitation training under the supervision of therapists. However, once patients are discharged from the hospital, they often lack professional guidance, and the effect of rehabilitation training is greatly reduced. This situation not only prolongs the rehabilitation time, but also may lead to incomplete recovery of joint function and even secondary injury. In addition, some existing rehabilitation equipment is often complex in design and cumbersome in operation, which is not conducive to independent use by elderly patients. Some equipment requires electric drive, which limits the flexibility of the place of use. These factors have reduced the patient's rehabilitation compliance to a certain extent and affected the rehabilitation effect. Therefore, it is necessary to develop a postoperative rehabilitation training device for hip and knee replacement that can standardize the postoperative rehabilitation training process of patients so that patients can effectively perform rehabilitation exercises after leaving the hospital; and make patients more energy-saving during exercise, thereby improving patient compliance and rehabilitation effects.
