Traction fixing equipment for foot fracture

Technical Field

The invention relates to the technical field of orthopedic equipment, in particular to traction fixing equipment for foot fracture.

Background

Fracture refers to the continuous complete or partial breakdown of bone structure. It is common to children and the elderly, and also occurs in young and middle-aged people. Patients often have one site fractured and a few multiple fractures. After timely and proper treatment, most patients can recover the original functions, and a few patients can leave sequelae with different degrees. The typical manifestations of fracture patients are local deformation after injury, abnormal movement of limbs, etc., and bone rubbing sound audible when moving limbs. In addition, the wound is extremely painful, with localized swelling, blood stasis, and dyskinesia after injury. The ultimate goal of treating fractures is to maximize the recovery of function of the injured limb. Therefore, in fracture treatment, three basic principles of reduction, fixation and functional exercise are very important.

After fracture reduction, because of instability, the fracture is easy to be relocated, so that the fracture needs to be fixed at a satisfactory position by adopting different methods to ensure that the fracture is gradually healed. Common fixation methods are: small splints, plaster bandages, external fixing supports, traction, braking and fixing and the like, and the fixing methods are called external fixing. If the fixation is made by surgical incision with steel plate, steel needle, intramedullary needle, screw, etc., it is called internal fixation. The fracture tractor is a common instrument for treating fracture, the existing fracture tractor respectively fixes thighs and shanks by fixing bands, then uses a heavy object to carry out traction, and the operation of adjusting traction force is very complicated, and the traction height can be adjusted according to the requirements of different patients and conditions.
