Proximal end of femur kirschner wire fixing device

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...

AI Technical Summary

Problems solved by technology

When using the existing guide for Kirschner wire positioning, there are the following defects: 1) The structure of the guide is complex, the operation is inconvenient, the operation time is long, and the risk of anesthesia is increased; 2) The wound is large, and the upper end of the femur needs to be cut. The skin, muscles and other tissues of the skin will aggravate local tissue damage, destroy blood supply, and increase the suffering of patients, especially for elderly patients, increasing surgical trauma, which does not conform to the concept of minimally invasive; 3) Kirschner wires passing through the medullary cavity will block the marrow Insertion of internal nails (or plates)
