A femoral distraction reducer and its application

Abstract

The invention provides a thighbone distraction repositor which comprises more than one fixing component and a main connecting rod. Each fixing component comprises a thighbone fixing needle, a clamping sleeve and a connecting component, one end of each connecting component is vertically connected with the main connecting rod, the other end of each connecting component is vertically connected with the corresponding clamping sleeve, sleeve tubes are arranged on the clamping sleeves, one end of each thighbone fixing needle internally sleeves the corresponding sleeve tube, each connecting component comprises a first fixing component and a second fixing component which are connected with the main connecting rod, the first fixing components are double-joint connectors, the second fixing components are sliding connectors, the first fixing components are fixedly connected on the main connecting rod in a threaded manner, and the second fixing components internally sleeve the main connecting rod through the sleeve tubes arranged on the second fixing components. By the aid of the thighbone distraction repositor, intra-operative X-ray fluoroscopy time and various operative complications caused by a traction table can be effectively decreased, an intramedullary nail guide needle can be more conveniently inserted, the success rate of implanting an interlocking screw is increased, and rotating deformity of a thighbone can be more effectively controlled.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a femoral distraction reducer and its application in femoral shaft fractures. Background technique [0002] Femoral shaft fractures are common fractures, accounting for about 5% of systemic fractures. They are more common in young and middle-aged people, and are mostly caused by falls and falls from heights. Since the femoral shaft is the longest and strongest bone in the human body, it has extremely important functions for the walking, standing and labor productivity of the human body. Effective treatment of femoral shaft fractures has great significance for reducing the disability rate. [0003] The femur is a long tubular structure, ranging from the level of the trochanter to the femoral condyle. There are many powerful muscle groups attached to it. After the femoral shaft is fractured, it is affected by multiple muscle forces and deforms the thigh. When the femur is n...
