Background technique

Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the changes of the times and society, the spectrum of orthopedic injuries has changed significantly. For example, diseases such as bone and joint tuberculosis, osteomyelitis, and poliomyelitis have significantly decreased, and trauma caused by traffic accidents has increased significantly.

After retrieval, the utility model with announcement number CN218458301U discloses a trauma orthopedic recovery training device, which belongs to the technical field of orthopedic recovery training. The key points of its technical solution include a shell, and a driving device is installed inside the shell. The driving device includes A motor installed inside the casing. The output end of the motor is fixedly connected to a connecting rod. The other end of the connecting rod is rotatably connected to a push rod. The other end of the push rod is rotatably connected to a slider. The inside of the casing A slide plate is installed, and a delay block is slidingly connected to the upper part of the slide plate, so that the motor drives the connecting rod to rotate, so that the push rod pushes the slide block to slide on the delay block. When the slide block contacts the front end of the delay block Finally, the slider pushes the delay block to continue to move forward, causing the slider to slide within the limit column. This solves the problem that most elderly people have poor physical fitness and are unable to perform recovery training on their own. The use of mechanical equipment requires a large range of equipment strength. , causing the patient to suffer pain in the affected area and resist treatment.

This device also has the following shortcomings during use: when used, the motor controls the rotation of the calf support plate and the thigh support plate to perform rehabilitation training for the patient. Since the motor needs a controller to be controlled during use, the elderly need to It is inconvenient to operate and has slow response, which can easily cause secondary injuries. Moreover, it can only train joints, and its function is too single, so the training effect is poor.
