Abstract

The invention relates to a proximal end of femur kirschner wire fixing device. The device comprises a connecting plate piece, wherein one end of the connecting plate piece is provided with a corresponding longitudinal locating hole, the longitudinal locating hole is detachably provided with a corresponding longitudinal sleeve, the other end of the connecting plate piece is provided with two transversal locating tubes, and each transversal locating tube is movably penetratedly provided with a transversal sleeve. The proximal end of femur kirschner wire fixing device has the advantages that thestructure is simple, the operation is convenient, the kirschner wire location is suitable, the kirschner wire is driven into two fracture broken ends, not only can effective fixed action be temporarily achieved, but also the implantation of an intramedullary nail (or a steel plate) is not influenced, minimally invasive can be achieved, and the treatment therapeutic effect of femoral intertrochanteric fracture or fracture of neck of femur is effectively improved.

Description

technical field [0001] The invention relates to a device for the operation of femoral intertrochanteric fracture and femoral neck fracture, in particular to a proximal femoral Kirschner wire fixation device, which is currently mainly used for temporary fixation in femoral intertrochanteric fracture surgery, and is also suitable for femoral neck fracture. Background technique [0002] With the aging of the society, intertrochanteric fractures of the elderly are increasing year by year. Elderly patients often have one or more medical diseases, and their tolerance to surgery is poor. It is necessary to adopt minimally invasive and less invasive surgery methods as much as possible. Closed reduction and percutaneous proximal femoral nail anti-rotation internal fixation is a minimally invasive procedure and is currently the main method for the treatment of elderly femoral intertrochanteric fractures. For intertrochanteric fractures with intramedullary nailing of the proximal fem...
