A knee joint rehabilitation device

Abstract

The invention discloses a knee joint rehabilitation device, which belongs to the field of medical equipment, and comprises an inclined plane slideway at an angle of 30° to the bed surface and a calf support plate connected to the inclined plane slideway through a rotating shaft. The front end of the calf support plate is provided with a foot plate Exercise mechanism; the rotating shaft is located in the middle of the calf supporting board, the calf supporting board can rotate around the rotating shaft, and the corresponding position of the inclined slideway is provided with a chute for the rotating shaft to move up and down along the inclined surface; the foot board exercising mechanism includes the insteps on both sides fixedly connected by connecting rods Pressing plate and sole push plate, both sides of the sole push plate are equipped with a rotating rod connected to the front end of the calf support plate; a detachable hydraulic cylinder is provided behind the rotating shaft in the cavity, and the rotating rod is connected to the side where one end of the calf support plate is located Extend to form a driving part connected with a rotating shaft or a hydraulic cylinder. The invention can realize the flexion and extension movement of the legs and the rotation movement of the foot plate, and promote the recovery of the knee joint; the driving control is convenient, the control of the flexion and extension movement is relatively stable, and the application value is high.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a knee joint rehabilitation device. Background technique [0002] The knee joint is a very important joint that supports the walking movement of the human body. There are many patients with knee joint diseases and knee joint injuries caused by various reasons in China, and the walking movement function of these patients is affected. Knees cannot be trained. We can only reduce the burden on the knee joints, protect the knee joints, and improve the nutritional status of the joints by increasing the lubrication of the knees and strengthening the 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 femur and the calf is the largest, and a certain space can be created between the soft tissues. Straighten the leg and lift it up vigorously, which is essentially muscle force, and the lubricating f...

AI Technical Summary

Problems solved by technology

It has the following disadvantages: one, in terms of exercising to help the knee joint rehabilitation, only the direct flexion and extension of the legs is performed, and the functional effect is relatively poor, which is also a common shortcoming of most knee joint rehabilitation devices in the prior art; The relationship between the bar and the calf frame is a sliding connection. When applied, the action point of the human calf will change, which is not conducive to the stable control of flexion and extension
