Knee joint rehabilitation training device

Abstract

The invention provides a knee joint rehabilitation training device. The device comprises a thigh fixing plate, a shank fixing plate, a shank supporting frame, an angle limiting mechanism, two pairs ofwinding mechanisms and a thigh supporting frame; a settlement groove is formed in the bottom surface of a sliding groove of the thigh fixing plate, and an ice bag can be limited in the settlement groove through an elastic band; the shank fixing plate is slidingly arranged in the sliding groove; the shank supporting frame is in pivot joint with the thigh fixing plate and is provided with a plurality of clamping grooves; the angle limiting mechanism is arranged on the thigh fixing plate, and the front end of each locking bolt of the angle limiting mechanism can extend into the corresponding clamping groove to lock the shank supporting frame; the winding mechanisms are arranged on the thigh fixing plate and the shank fixing plate respectively, one end of a pulling rope connected to each winding mechanism penetrates through a corresponding through hole and is connected with one end of a corresponding fixing belt; the thigh supporting frame is used for controlling the lifting range of thethigh. The knee joint rehabilitation training device can fix the thigh and the shank at any angle, have the functions of knee joint flexion practice and knee joint straightening practice and be folded, stored and conveniently carried.

Description

technical field [0001] The invention relates to an auxiliary medical device for human body, in particular to a knee joint rehabilitation training device. Background technique [0002] At present, in the rehabilitation treatment of patients with knee joint injuries, knee joint stiffness is a very common phenomenon. After periarticular fractures, patients are prone to joint movement disorders. The morning and evening of postoperative exercise and the method of exercise will directly affect the joint function. The effect of functional rehabilitation; the traditional treatment principle for periarticular fractures is to repair the pathological tissue and then fix it, and then perform functional exercise after the tissue heals. However, most patients cannot move for a long time during the healing process, which will cause joint capsule adhesion and lead to Joint stiffness, especially fractures around the knee joint, because the knee joint bears a lot of weight and has a complex s...

Problems solved by technology

However, for this straightening method, the experience of doctors, nurses and patients is not ideal. Specifically, it is inconvenient for doctors and nurses to take sandbags, and patients will move because of the pain when the knee is straightened, resulting in sandbag displacement or knee injury. Generally, the weight of sandbags in hospitals is not adjustable, and the weight of sandbags placed on patients’ knees is not completely scientific and reasonable most of the time.

In addition, the existing knee joint bending exercises and knee joint straightening exercises use different equipment, and it is very troublesome for patients to switch back and forth for rehabilitation training
