Description

Simple femoral intramedullary nail needle insertion point guider

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a simple femoral intramedullary nail needle insertion point guider.

Background

The proximal fracture of the femoral shaft and the femur is a very common fracture, intramedullary nail internal fixation is a very common treatment method with good curative effect at present, and the operation modes of the intramedullary nail internal fixation comprise incision reduction and closed reduction, wherein the incision reduction can enable the fracture to achieve good reduction, but the fracture is easy to delay healing or not heal due to the damage of blood circulation of the local part of the fracture, the increase of the operation blood loss and the obvious increase of the infection chance, the closed reduction has light damage to soft tissues and does not damage the blood circulation of the fracture end, so the healing time is shorter than that of the open reduction, the healing effect is good, and the blood loss and postoperative infection can be reduced.

Although the closed reduction intramedullary nail has the advantages, the guide pin needs to be inserted into the medullary cavity at the proximal end of the fracture from the vertex of the greater trochanter and enters the medullary cavity at the distal end of the fracture through the fracture end during the operation, and in the process, the guide pin is very difficult to be inserted into the medullary cavity at the proximal end of the fracture from the vertex of the greater trochanter, and the specific characteristics are that firstly, the determination of the needle insertion point is difficult, because the intramedullary nail is slightly inwards inserted at the junction of the front middle third of the vertex of the greater trochanter, the gluteus medius muscle is attached at the vertex of the greater trochanter, and the inner side of the gluteus minimus muscle is quickly continued to the femoral neck in a steep slope, so the area of the needle insertion point is very small and is not easy to be determined, the needle point is easy to be displaced during the needle insertion after the determination, the incorrect needle insertion point can cause the difficulty in the intramedullary nail insertion and even cause iatrogenic fracture, and secondly, if the, the femoral intramedullary nail is always shifted outwards and upwards, so that the vertex of the greater trochanter is inclined towards the deep part of the body, the included angle between the needle inserting direction and the longitudinal axis of the fracture proximal section is reduced, and the needle inserting difficulty is caused.
