Knee joint rehabilitation device

Abstract

The invention discloses a knee joint rehabilitation device, and belongs to the field of medical apparatuses. The knee joint rehabilitation device comprises a slope slide way which forms an included angle of 30 degrees with a bed face and shank supporting plates which are rotatably connected to the slope slide way through a rotary shaft, and foot sole exercising mechanisms are arranged at the frontends of the shank supporting plates; the rotary shaft is located in the middles of the shank supporting plates, the shank supporting plates can rotate around the rotary shaft, and a slide groove forthe rotary shaft to move up and down along a slope is formed in the corresponding position of the slope slide way; the foot sole exercising mechanisms comprise instep pressing plates and foot sole pushing plates, the two sides of each instep pressing plate and the two sides of the corresponding foot sole pushing plate are fixedly connected through connecting rods, and rotary rods which are rotatably connected with the front ends of the shank supporting plates are arranged at the two sides of the foot sole pushing plates; a detachable hydraulic cylinder is arranged at the portion, behind the rotary shaft, in a cavity, and the sides, connected with the ends of the shank supporting plates, of the rotary rods extend to form a driving part connected with rotary shaft or the hydraulic cylinder.By means of the knee joint rehabilitation device, flexion and extension motion of the legs and the rotation motion of the foot soles can be achieved, and the rehabilitation of the knee joints is promoted; the driving operation is convenient, the control over the flexion and extension is 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
