Description

A knee joint rehabilitation training robot

Technical Field

The utility model relates to the technical field of rehabilitation equipment, in particular to a knee joint rehabilitation training robot.

Background Art

Rehabilitation therapy, also known as rehabilitation physical therapy, is a comprehensive treatment method that integrates exercise therapy, occupational therapy, speech therapy, physical therapy, acupuncture, cupping, and massage. Exercise therapy is a special therapy that prevents, improves, and restores the patient's physical dysfunction and hypofunction through passive exercise therapy, active exercise therapy, and resistance and exercise therapy. Joints are very important joints that support human movement. Joint diseases and various reasons can cause knee joint injuries. During rehabilitation, the burden on the knee joint is reduced, the knee joint is protected, and the nutritional status of the joint is improved by increasing knee lubrication and strengthening leg muscles. There is lubricating fluid in the gap between the soft tissues of the knee. When the legs are straightened, the distance between the thigh bone and the calf bone is the largest, and a certain space can be generated between the soft tissues. The leg straightening is actually muscle force, which can press the lubricating fluid into the gap between the soft tissues of the knee to supplement the nutrition of the soft tissues. This can enhance the wear resistance of the soft tissues for a long time. Therefore, knee joint exercise is beneficial to the rehabilitation of the knee joint.

An existing knee joint rehabilitation training robot (publication number: CN215081671U) has at least the following disadvantages:

When the above patent is in use, the second rack is driven to slide vertically by the power gear, so that the leg support block rotates clockwise by a certain angle, and the knee joint is driven to bend by the leg support block, so that the knee joint is trained. Since the above patent does not have a mechanism for massaging the knee joint, the knee joint rehabilitation training robot requires a long period of training. If the robot does not have a massage function, the patient's muscles will become sore and swollen during long-term training, making the patient feel tired and uncomfortable, which is not convenient for the patient's rehabilitation training.
