Description

Technical Field [0001] The present invention relates to a segmented plate assembly for remedy of fracture bone,

The present invention relates to a segmented plate assembly for bone joining. More particularly, the present invention relates to a segmented plate assembly for bone joining that connects a plurality of segmented plates to a shape of a fractured bone.

If the bones of a human body are injured by trauma, it is most common to perform a plate (or plate) fixation using fracture treatment plates to join the bones.

Plate fixation is a surgical procedure for restoring a fractured bone to its original position and angle, placing a plate for fracture treatment, and fastening the fractured bone by fastening the fractured bone plate with a screw.

In order to improve the success rate and accuracy of the operation, it is very important to select a plate suitable for the position and shape of the fracture site.

However, most of the plates to be supplied are rectilinear rectangles, which differ only in thickness and length.

On the other hand, the bones of the human body are slightly bent at a specific angle depending on the male and female or physical characteristics, and the bones protrude stoutly around the joints.

When a straight plate is used at the fracture site due to the shape of the bone, the plate is slightly protruded above or below the bone.

 In the operating room, a rectangular plate is bended or warped when a pelvic bone, which is a cylindrical bone except the iliac bone, or an S-shaped clavicle, is operated.

However, this method requires a long operation time and has a limitation in realizing the plate to perfectly match the shape and the shape of the fracture site.

In order to solve this problem, an assembly for connecting the plates of the cut type to the steel wires has been proposed to form the length and shape of the plate similar to the shape of the fractured bone. However, this is because the connection between the plates is made only by the steel wire, so that the joined state of the bones is not firmly maintained.

In addition, in order to remove or replace the intermediate plate after the steel wire is fastened, it is necessary to remove the entire steel wire and then fasten the steel wire again. .

Korean Patent No. 10-1096877 (December 14, 2011)

A segmented plate assembly (10) for bone joining according to the present invention comprises a unit plate (100), a connecting member (200) and a steel wire (300).

Specifically, one segmented plate is formed by a plurality of unit plates 100 arranged in the shape of a bone and a connecting member 200 disposed between the unit plates 100, And the steel wire 300 is wrapped around the outer side to complete the segmented plate assembly 10 for bone joining.

More specifically, the unit plate 100 includes a plate body 110 having a fixing hole 112, a first female connecting portion 120, and a second female connecting portion 130.

Referring to FIG. 2, the plate body 110 of the unit plate 100 is a hexahedron, and a fixing hole 112 through which a screw passes is formed at the center of the plate body 110.

Accordingly, the unit plate 100 can be fixed to the bone using a screw.

Further, on the four side surfaces of the plate body 110, female connection portions 120 and 130, which can be engaged with the connection member 200, are protruded.

Specifically, the first and second female connection portions 120 and 120 are provided on the pair of opposite side surfaces, respectively.

The female connection portions 120 and 130 are formed such that the male connection portions 220, which will be described later, are slidably inserted to the side of the female connection portions 120 and 130.

Specifically, a female-type space 121 and a neck-insertion portion 123 are provided on the inner side of the female-type connecting portions 120 and 130 to extend through the female-type connecting portions 120 and 130.

The female type space 121 is formed in a cylindrical space and the neck insertion part 123 is provided in a slit shape on the front surface of the female type connecting part 120 so that the outer circumferential surface of the female type space 121 can communicate with the outside.

The upper and lower spaces of the neck insertion part 123 are formed to be lower than the diameter of the female type space 121 so that the joint bar 221 of the male type connecting part 220 inserted into the female type space 121 is inserted forward So that it can not be separated.

In the embodiment of the present invention, the female type space 121 has a cylindrical shape. However, the female type space 121 is not limited thereto and may be formed in any shape as long as a later-described joint bar 221 can be inserted.

At this time, the female-shaped spaces 121 and 131 and the neck-inserted portions 123 and 133 of the first female-type connecting portion 120 and the second female-type connecting portion 130 may be formed in the same shape.

The first and second female connection portions 120 and 130 may have different lengths extending from the plate body 110.

The female connection portions 120 and 130 are connected to the connection member 200 by inserting the male connection portion 220 and are also arranged to fix the steel wire.

3, the connecting member 200 is provided with a connecting body 210 having a hexahedral shape, and male connecting portions 220 are protruded from both sides of the connecting body 210.

The male coupling part 220 is inserted into the female coupling parts 120 and 130 of the unit plate 100 and includes a joint bar 221 and a neck 223.

The joint bar 221 and the neck 223 are formed in such a manner that they can be respectively inserted into the female spaces 121 and 131 and the neck inserts 123 and 133.

In other words, the joint bar 221 is a cylindrical shape that can be inserted into the cylindrical female type spaces 121 and 131, and the neck 223 has a thin rod shape provided between the connection body 210 and the joint bar 221 .

On the other hand, in order to realize the shape of the fractured bone by connecting the unit plates, there must be a gap in each connecting part.

The joint bar 221 and the neck 223 are formed to be slightly smaller than the female-shaped space 121 and the neck-inserted portion 123, respectively.

The outer surfaces of the joint bar 221 and the neck 223 and the inner circumferential surfaces of the female type space 121 and the neck type insertion portion 123 are spaced apart from each other by a predetermined space.

As described above, since the joint bars 221 of the male connector part 220 inserted into the female space 121 can not be separated from the front of the female connector parts 120 and 130, the thickness of the joint bar 221 Should be formed to be thicker than the height of the neck insertion portion 123.

4 to 5, the first female connection portions 120 are connected to the connection member 200, and the second female connection portions 130 are shown to fix the steel wire.

After the plurality of unit plates 100 and the plurality of connecting members 200 are connected to each other to complete the segmented plate corresponding to the shape of the bones, the steel wire 300 is wound around the female threaded portions 121, .

In this case, a generally used cable is preferably used for the steel wire 300, but it is possible to use a K-wire or a Kirshner's wire or roll wire, and these steel wires can be bent to fit the shape of the bone .

The plate assembly 10 applies tension to the steel wire wrapped around the outer surface so that the assembled plates exert a force in the direction of close contact of the fractured bones, which facilitates union of the bones, To keep it firm.

Meanwhile, both ends of the steel wire 300 may be fixed using a known wire fixing clip 301 as shown in FIG.

5, both ends of the steel wire 300 are positioned on the neck insertion part 123 and an external force is applied to the upper and lower sides of the neck insertion part 123 using a mechanism such as a plier, The end of the steel wire 300 may be fixed.

This fixing method is not required separately for the wire fixing clip 301, and the method is simple, thereby providing convenience to the operator.

Since the neck inserts 123 and 133, which are the openings into which the steel wire 300 is inserted, are opened in a slit shape to be connected to the outside, the unit plate 100 positioned in the middle after the steel wire 300 is disposed is removed , Replacement, change, and the like can be freely performed, thereby facilitating the operation.

Referring to FIG. 6, one side of the connecting member 200 is connected to the second female connector 130 and the other side is connected to the female connector 120.

In this way, the connection direction of the unit plate 100 can be appropriately changed and applied according to the situation of the bone, etc., and it is easy to realize the plate according to the segmented bone shape.
