Description

{Grip plate for trochanteric fracture of femur}

The present invention relates to a metal plate which can be fixedly bonded to a fracture site in a femur trochanter to treat fractures occurring in the femoral electron.

Medically, the femur is the bone between the jawbone and the tibia, and the side of the femur near the pelvis is called the proximal part. Here, the proximal part is composed of the femoral head constituting the head part, the femoral part constituting the proximal lower part, and the femoral neck part connecting the two.

Among these, the femoral electron part is referred to as the upper part of the femur, the lower part as the electron part, and the part connecting the two parts is called the electron part. The fracture caused by the external force of the femoral electron part is a tendency to occur due to rapid aging of the population to be.

As a method of treating fractures on the femoral electronic part, a method of inducing union using a fixation device firmly fixed on the fracture site is generally used in order to reflect the characteristics of the femoral electron part rich in cavernous bone. Prior art documents related to the prior art for treating bone fracture by internal fixation on the fracture site on the femoral electronic part include "a fastener metal fixing plate for bone fusion" (hereinafter referred to as "prior art Quot;).

 In this conventional technique, for the treatment of the fracture occurring on the femur electronic part, the shape of the electron part is reflected and the hooked part is placed on the electron, and the body formed by the extension is positioned on the interelectrode area, .

However, in such a conventional technique, the shape of the metal plate fixed to the outside of the bone is provided integrally so that it can not have the structural deformation and flexibility corresponding to the shape of the bone. As a result, the internal fixation reflecting the shape of the various femoral electronic parts and the fracture site is difficult In addition, there has also been a problem of insufficient fixing of the metal plate and lack of separation of the fracture site by adopting a method of fixing the sub-main body in which one side of the claw shape is tightly fixed to the large electron side is fixed to the electron side.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide an apparatus and a method for adjusting the shape of a femur and a variety of fracture sites, And to provide a technique that can be improved.

In order to attain the above object, the present invention provides a fixed metal plate for treating a femur electronic fracture, comprising: a support member having a first guide groove formed in a lengthwise direction from an upper end thereof and formed of a metal plate having a predetermined thickness; And a latching member inserted into the first guide groove at an upper side of the support member and provided in a hook shape.

Here, the support member may include a plate-like first support portion; A second support portion extending from the upper end of the first support portion so as to be convexly bent outwardly and having a predetermined open space formed at the center thereof; And a third support portion extending from an upper end of the second support portion and having a first guide groove formed along a longitudinal direction at a center thereof.

At least one second guide groove may be formed in the third support portion so as to form a predetermined angle with the first guide groove. The second guide groove may be formed in the same shape as the first guide groove, do.

The supporting member may further include a fixing part protruding from an outer surface of the first supporting part and having at least one wire insertion hole provided along the width direction of the first supporting part.

Meanwhile, the latching member may include a latching portion provided to be bent in a convex shape toward the upper side; And an engaging portion extending from one side of the engaging portion to a shape corresponding to the first guide groove.

Here, the latching portion is opened along a bent shape at the other predetermined region to form at least two hook-shaped protrusions.

The present invention has the following effects.

First, the support member is fixed to the femur interelectrode region, and then the engaging member is inserted and coupled along the first guide groove provided on the support member, thereby improving the internal fixability of the metal fixture plate And can provide structural flexibility to correspond to the anatomical shape of the different femoral inter-lingual regions according to each person.

Secondly, since the second guide grooves are formed on the support member in various directions, it is possible to provide a variety of insertion directions of the fastening members, so that an optimized fixed shape reflecting the shape of the femoral electron and the diversity of the fracture portions is applied can do.

Third, providing improved internal fixation and increasing the degree of adhesion on the fracture site may result in faster bone union on the fracture site.
