Auxiliary reduction apparatus for closed reduction of femoral shaft fracture of children

Abstract

The invention discloses an auxiliary reduction apparatus for closed reduction of femoral shaft fracture of children and belongs to the technical field of orthopedic medical treatment instruments, aiming to realize closed reduction of femoral shaft fracture of children. The technical scheme includes that a proximal clamp holder and a distal clamp holder reslectively sleeve a proximal connecting rodand a distal connecting rod through lock bolts; a Kirschner wire is fixedly connected with the proximal end of the femoral fracture through the proximal clamp holder; a half-thread wire is fixedly connected with the distal femoral condyle through the distal clamp holder; a horizontal rotating shaft is connected to the far end of the proximal connecting rod and is connected with a universal shaft;the universal shaft is connected with the distal connecting rod; an axial stretching reduction device is mounted at the tail end of the distal connecting rod, and a radial pressurizing reduction device is mounted on the distal connecting rod. The auxiliary reduction apparatus has the advantages of simple structure, convenience in use, good reduction effect, high convenience in fluoroscopy duringoperation, creates condition for driving of titanium elastic intrameduary nail for treatment of femoral shaft fracture of children, avoids the fracture broken end surgical reduction operation, and accordingly reduces surgical wounds.

Description

technical field [0001] The invention relates to an auxiliary reset device for closed reduction and internal fixation for treating femoral shaft fractures in children, and belongs to the technical field of orthopedic medical devices. Background technique [0002] Femoral shaft fractures in children are common fractures, accounting for about 21.7% of pediatric orthopedic hospitalizations, and are often caused by participating in sports activities or outdoor sports. For femoral shaft fractures in children aged 2-11, closed reduction and fixation with titanium elastic intramedullary nails is the most commonly used surgical method at present. It has the advantages of shortening, fewer complications, and less psychological impact on children and their families. Especially compared with plate fixation, elastic intramedullary nail fixation can effectively protect the internal environment of femoral shaft fracture healing in children, allow slight movement of the fracture end, and s...

AI Technical Summary

Problems solved by technology

Traction of the lower limbs or extracutaneous U-shaped reduction rods are commonly used in current closed reduction surgery. These reduction methods are indirect reduction and cannot directly act on the femur. The effect is not ideal, resulting in many femoral shaft fractures having to be reduced by incision at the fracture end. , increased trauma
