Description

An orthopedic medical rehabilitation device specially used for tibia and fibula distraction reduction

technical field

The invention relates to the technical field of medical devices, in particular to an orthopedic medical rehabilitation device specially used for tibia and fibula traction and reset.

Background technique

Orthopedics 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 development of traditional Chinese medicine, the treatment of orthopaedic diseases has gradually become popular. Traction therapy is a widely used treatment method in orthopaedic therapy. Traction therapy is the use of appropriate continuous traction to achieve restoration and maintenance reduction.

The tibia and fibula are the collective name of the tibia and the fibula, and are the bones of the legs in the human body. Single fracture of tibial shaft, double fracture of tibia and fibula, and single fracture of fibular shaft are the most common fractures in the whole body. Because the closeness of the physiological position and injuries are often complicated, they are collectively referred to as tibia and fibula fractures, especially in children under 10 years old. Among them, single fracture of tibial shaft is the most, followed by double fracture of tibia and fibular shaft, and single fracture of fibular shaft is the least. The tibia is the main bone that supports the weight below the femur, and the fibula is the important bone that attaches to the calf muscles and bears 1/6 of the weight. The shape of the middle and lower 1/3 of the tibia changes, which is prone to fracture, and the fracture of the upper 1/3 of the tibia is displaced, which is easy to compress the popliteal artery, resulting in severe ischemic gangrene of the lower leg. Blood stasis in the middle 1/3 of the tibia can close the osteofascial compartment of the calf, increasing the pressure in the chamber and causing the ischemic muscle contracture to gangrene. Fractures of the middle and lower 1/3 of the tibia result in the rupture of the nourishing artery, which can easily lead to fractures and delay healing.

The existing leg traction device is troublesome to install, time-consuming, labor-intensive, and expensive. At the same time, the adjustment convenience of the traction bracket is poor, and the control force is not very uniform, which brings great inconvenience to medical staff. The leg traction sleeve has a single structure, does not have physiotherapy function, and cannot meet the higher requirements of modern orthopaedic medical care.
