Abstract

The invention provides a femur fracture strutting reducing device, and belongs to a medical apparatus. The femur fracture strutting reducing device comprises a first extension rod and a second extension rod, the two ends of the first extension rod and the second extension rod are connected together through a first pipe clamp and a second pipe clamp respectively, a first extender and a second extender are arranged in the middles of the first extension rod and the second extension rod respectively, a Steinmann pin sleeve is fixed to one end of the first extension rod through a third pipe clamp, a Steinmann pin is arranged in the Steinmann pin sleeve, a semi-ring rod is fixed to one end of the second extension rod through a fourth pipe clamp, a first Kirschner pin is fixed to the semi-ring rod through a first tubular pin clamp and a second tubular pin clamp, and a second Kirschner pin perpendicular to the first Kirschner pin is fixed to the semi-ring rod through a third tubular pin clamp. By means of the femur fracture strutting reducing device, when closed reduction is carried out, the femur fracture strutting reducing device can be combined with a magnetic force navigation intramedullary needle to treat the femoral shaft fracture, the closed reduction aim is achieved, the operation flexibility during an operation is greatly improved, and complications caused by applying a traction table to carry out reduction are avoided.

Description

technical field [0001] The invention provides a medical device, especially an orthopedic device. Background technique [0002] Femoral interlocking intramedullary nail fixation is the gold standard for the treatment of femoral shaft fractures. However, although intraoperative X-ray fluoroscopy has become quite popular, there are still some difficulties in closed reduction of femoral fractures. In addition, the excessive use of X-ray fluoroscopy during the operation is also unacceptable to most surgeons, which has led many orthopedic surgeons to still use open reduction and intramedullary nailing for the treatment of femoral shaft fractures. Traction table reduction is currently the traditional method used by most orthopedic surgeons in femoral shaft fracture surgery, but the special position of the traction table limits the flexibility of intraoperative operations, especially for healthy or obese patients. Difficult and prone to complications such as intraoperative femoral ...
