Bone plate

The present invention relates to a bone plate, and more particularly to a bone plate to facilitate the fixation of the bone regardless of the fracture site of the bone.

The human body includes many bones, such as the pelvis, spine, humerus, radius, ulna, bones of the hands, femurs, tibia, calf bones, bones, and the like.

Many bones included in the human body can fracture when an external shock is applied. That is, the human body may be broken by falling from a high place, falling or being stumbled while walking.

When the bones of the human body fractures the gibbs (gibbs) from the outside of the body, so that the bonding of the bones is made.

In the case of severe bone fractures, the bone plate is attached directly to the bone for fixation to the bone, and then fixed by screws to allow the bone to be joined. An example of a bone plate is disclosed in Korean Patent Publication No. 2008-36082 'bone plate having a movable locking element'.

Existing bone plate can be easily used when the middle part of the bone fractures to secure enough screw fixing area used to fix the bone plate on both sides of the fracture site, but when the fracture site is biased to one end of the bone, If a fracture occurs in the surgical procedure is difficult to secure the screw fixing area there is a problem that is difficult to use.

In addition, the shape of the middle portion of the bone is cylindrical, but the shape of the bone is changed toward the end of the bone, so when the fracture site is biased to one end of the bone, there is a problem that it is difficult to fix the bone plate of a simple form in close contact with the bone.

In addition, when the bone plate is not tightly fixed to the bone there is a problem that the treatment procedure is also complicated, such as poor fixation state of the bone plate is reduced, the incision area of the skin is large.

The present invention has been made to solve the above problems, one end of the bone plate is formed to be bent to surround the end side of the bone to provide a bone plate that can be tightly fixed to the bone even when the fracture site of the bone is close to the joint site For the purpose of

In addition, an object of the present invention is to provide a bone plate that is easy to secure the screw fixing area for fixing the bone plate even when the fracture site of the bone is close to the joint site because one end of the bone plate is formed in accordance with the shape of the bone.

In order to achieve the above object, the present invention, in the bone plate to be fixed to the bone separated into the first and second bone fragments by fracture, it is formed in a straight shape to be attached along the first bone fragment, A first fixing part curved corresponding to a surface of the first bone piece; And a second fixing part which is bent to correspond to the surface of the second bone piece and is bent to be attached along the side surface of the second bone piece, and includes a plurality of fixing parts on the first fixing part and the second fixing part. It provides a bone plate characterized in that the fixing hole is formed.

At least some of the plurality of fixing holes may have a long hole shape.

The long hole-shaped fixing hole may be formed only at one side selected from the first fixing part and the second fixing part.

The present invention as described above, one end of the bone plate is bent to surround the end side of the bone can be fixed in close contact with the bone even when the fracture site of the bone is close to the joint site.

In addition, in the present invention, since one end of the bone plate is formed in accordance with the shape of the bone, it is easy to secure a screw fixing area for fixing the bone plate even when the fracture portion of the bone is close to the joint portion.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1a and 1b is a front view and a side view showing the configuration of a bone plate according to an embodiment of the present invention.

1A and 1B, a bone plate 100 according to an embodiment of the present invention includes a first fixing part 110 and a second fixing part 120.

The bone plate 100 is attached to the side of the fractured bone so that the separated bone pieces are coupled to each other. Here, the fractured bone to describe the configuration of the bone plate 100 will be referred to as the first and second bone pieces (1a, 1b). Here, it is assumed that the first bone piece 1a is the middle part of the upper arm bone, and the second bone piece 1b is the joint side of the upper arm bone, that is, the distal part.

The first fixing part 110 is one end of the bone plate 100, is formed in a straight shape having a predetermined length and width to be attached to the front surface of the first bone piece (1a). Here, since the bone of the human body is formed to increase in diameter from the middle portion to both ends, the first fixing portion 110 is preferably formed to be curved to the extent corresponding to the surface curvature shape of the first bone piece (1a).

Here, the width of the first fixing part 110 is preferably smaller than the diameter of the bone, it is preferable to facilitate attachment to the bone.

The second fixing part 120 is continuously connected to the first fixing part 110 as the other end of the bone plate 100. Therefore, the second fixing part 120 is preferably formed with the same width as the first fixing part 110.

The second fixing part 120 is curved to correspond to the surface shape of the second bone piece 1b to be easily attached to the second bone piece 1b. In addition, the second fixing part 120 is preferably bent to surround the side of the second bone piece (1b) to be easily attached to the second bone piece (1b). According to the drawing, the second fixing part 120 is bent in a form that covers only a portion of the second bone piece 1b, but the degree of bending may be set in various ways according to the needs of the operator. In addition, the bending direction of the second fixing part 120 may be changed in the middle part.

On the bone plate 100 including the first and second fixing parts 110 and 120 connected to each other, a plurality of fixing holes 130 are formed at regular intervals along the center line.

A fixing screw for fixing the bone plate 100 attached to the bone is connected through the plurality of fixing holes 130.

Here, some of the fixing holes 130 of the plurality of fixing holes 130 may be formed in the form of a long hole. The long axis of the fixing hole 130 in the form of a long hole is preferably formed in the longitudinal direction of the bone plate (100).

In addition, some of the fixing holes 130 of the fixing holes 130 may have a spiral formed on the inner circumference thereof to facilitate fixing of the fixing screws.

Here, the number and size of the fixing holes 130 may be variously formed according to the needs of the operator.

The fixing hole 130 having a long hole shape may be formed on the first fixing part 110 or the second fixing part 120. In addition, the long hole-shaped fixing hole 130 may be formed anywhere on the bone plate 100, but is formed on the first fixing portion 110 that is attached to the straight bone pieces, that is, the first bone piece (1a) side It is preferable.

In addition, depending on the needs of the operator, the fixing hole 130 of the long hole shape and the fixed hole 130 of the garden type may be formed alternately.

The use of the present invention configured as described above will be described.

It is assumed that the bone plate 100 according to the present invention is used in the fracture of the upper arm.

2 to 4 is a view showing a state of use of the bone plate according to an embodiment of the present invention.

First, the operator brings the first and second bone fragments 1a, 1b of the upper arm bone generated by the fracture closer to each other.

As shown in FIG. 2, in a state where the first and second bone pieces 1a and 1b are close to each other, the first fixing part 110 is located at the side of the first bone piece 1a and the second fixing part 120 is disposed. Is in close contact with the second bone piece 1b side.

Thereafter, as shown in FIG. 3, the fixing screw is inserted through the fixing holes 130 formed in the first and second fixing parts 110 and 120. At this time, it is preferable that the fixing screw is not inserted completely and is inserted only to the extent that the fixing screw is not separated from the set state of the fixing screw.

When the position setting is completed, the fixing screw inserted into the fixing hole 130 of the second fixing part 120 attached to the distal side, that is, the second bone piece 1b side is completely inserted so that the second fixing part 120 is Secure to the distal side.

Although the 1st bone piece 1a and the 2nd bone piece 1b are adjacent, it has a predetermined space | interval. The operator measures the first bone piece 1a to be in close contact with the second bone piece 1b. Since the fixing hole 130 on the side of the first bone piece 1a has a long hole shape, it is not necessary to remove the fixing screw when the first bone piece 1a moves.

After the ends of the first bone piece (1a) and the second bone piece (1b) are in close contact with each other, the operator is completely inserted into the fixing screw to form the first bone piece (1a) and the second bone piece (1b) by the bone plate 100 To a state as shown in FIG. 4.
