Description

{CONNECTOR FOR HIGH TIBIA OSTEOTOMY}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ligament used in a tibial proximal osteotomy, and more particularly to a ligament that fixes a tibia in a tibial proximal osteotomy.

In general, the tibial proximal osteotomy is performed by osteotomy for osteoarthritis of the legs bent osteoarthritis, correcting the tibia by osteotomy, and dispersing the load of the weight concentrated inside the arthritic knee joint to reduce the pain This method is also used for the correction of a patient who has severe knee flexion and pain in the knee joint.

In order to correct the twisted leg, normally, the bones are cut in the bent direction in order to straighten the bruised bone, and then the gap is inserted and fixed in the gap, and the gap is maintained. I correct my bent legs by filling my bones.

Typically, in the tibial proximal osteotomy, a metal tie is used to fix the osteotomized tibia and fix the inserted osteotomy (or support block). Conventional ties for the tibial proximal osteotomy are disclosed in Korean Patent No. 10-0641312 and Japanese Patent Application No. 10-1253915 of the present applicant. In the disclosed joint (metal fixture), a bone is fixed to the upper and lower portions of a tibial incision using a screw, and a screw insertion hole (not shown) is formed to fix a bone- Through holes) are formed.

However, in the tibial proximal osteotomy joint of the prior art, the through hole for fixing the osseointegrated portion is formed as a small hole into which the osseoused portion can be inserted, so that the insertion position of the osseointegrated portion can not be adjusted. Therefore, when the incision position of the bone is high, the position of the screw insertion hole is increased and the upper end of the joint is protruded above the knee joint. When the incision position of the bone is low, And there is a problem that the effect of the operation such as the finishing of the suture thread is reduced by the position of the joint region and the binding sphere is too large.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems of the prior art, and it is an object of the present invention to provide an apparatus and a method for adjusting a position of insertion of a bone- The tibial osteotomy can be performed in a variety of ways.

In order to solve the above-described problems, the present invention provides a tibial bone for use in proximal tibial osteotomy, comprising a tibial body used for tibial proximal osteotomy and a tibia for fixing a tibia, and a support block, And a positioning opening capable of adjusting an insertion height of the support block inserted into the opened tibia is formed on the side surface.

Here, one of the positioning openings may be formed on the left or right side of the binding body, and two positioning openings may be formed on the left and right sides of the binding body.

It is further preferable that the positioning opening has an opening height at least twice the height of the supporting block.

The present invention is characterized in that the binding body includes a first screw through hole formed in the upper portion of the binding body to fix the binding body to the tibia and a second screw thread hole formed below the first screw through- A through hole, and a third screw through hole formed in a lower portion of the positioning opening.

According to the improved structure of the tibial proximal tibial osteotomy according to the present invention, since the insertion position (height) of the osteotomized portion can be adjusted, the position of the incision at which the operator cuts the bone is too high, There is an advantage in that the tie bones for proximal tibial osteotomy can always be fixed at an appropriate position even when the incision is made.

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

1, the tie bar 100 for tibial proximal osteotomy according to the present embodiment includes a binding body 101, first to third screws 120, 121 and 122, and left and right support blocks 131 and 132, The main body 101 is configured to be engaged with the lateral side of the tibia formed in the tibial proximal osteotomy, so that the bony portion 11 of the opened tibia is fixed so as not to move. The binding body 101 of this embodiment is made of a metal and is formed into a T shape.

The binding body 101 is disposed so as to connect the side surfaces of the bony portion 11 of the tibia and fixes the binding body 101 and the tibia 10 via the screws 120, (10) is fixed so as not to move.

In this embodiment, three first screws 120 are passed through the first screw through holes 103 (see Fig. 2) of the binding body 101 at regular intervals in the horizontal direction on the top of the T-shaped binding body 101 And is fixed to the central portion 111 of the binding body 101, that is, the lower end of the first screw through hole 103 and the upper portion of the positioning openings 115 and 116 at regular intervals in the vertical direction, Two second screws 121 are screwed into the tibia 10 through the second screw through hole 105 of the binding body 101 (see Fig. 2), and the four screws 121 formed at the bottom of the positioning openings 115, The third screw 122 is threaded through the threaded through hole 106 and is fixed to the lower tibia 10 which is cut to fix the cut tibia 10 firmly.

On both sides of the central portion 111 of the binding body 101, the left positioning opening 115 and the right positioning opening 116 are formed in the same size and shape. The left and right positioning openings 115 and 116 are inserted and supported by two left and right support blocks 131 and 132 for maintaining the spacing of the osteotomes 11. That is, the left and right support blocks 131 and 132 are inserted into the cut-and-raised portion 11 cut at one side 131a and 132a (see FIG. 2) to maintain the spacing of the cut- , 132b are inserted into the positioning openings 115, 116 and fixed so as not to shake or swing.

Referring to FIG. 2, the left and right support blocks 131 and 132 have a sloped top surface. When the tibia 10 is cut to correct the tibia, the cutting interval of the bent side (the height of the bent portion 11) is large in order to correct the tibia 10 tilted toward the bent side, and the cutting interval is small Loses. Therefore, in the case of the support blocks 115 and 116 to be inserted into this gap (the osculating portion 11), it is preferable that the upper surface is inclined in accordance with the inclination.

The left and right positioning openings 115, 116 are preferably sized such that three support blocks can be inserted. It is preferable that the height h of the positioning openings 115 and 116 is three times the height of the support blocks 115 and 116 and the width w of the positioning openings 115 and 116 is equal to the width of the support blocks 131 and 132. The left and right positioning openings 115 and 116 are configured to protrude from both sides of the central portion 111 of the binding body 101.

The position of the osteolysis part 11 can be raised or lowered due to a mistake of the operator who cuts the tibia 10 or various reasons. FIG. 1 shows a case where the position of the osteotomy portion 11, which is a cutting portion of the tibia 10, is cut to a high degree, and FIG. 3 shows a case where the cutting position of the osteosynthesis portion 11 is cut to a low degree.

 In the structure in which the insertion height of the support block can not be adjusted as in the case of the tibial proximal osteotomy joint of the related art, when the position of the osteolysis portion 11 is increased, the upper end of the binding body 101 protrudes above the knee joint with the cartilage C However, in the present invention, when the position of the osteolysis part 11 becomes higher as shown in FIG. 1, the left and right support blocks 131 and 132 are inserted into the upper side of the left and right positioning openings 115 and 116) The upper end of the binding body 101 can be adjusted so as not to protrude above the knee joint.

3, the left and right support blocks 131 and 132 are closely contacted with the lower ends of the left and right positioning openings 115 and 116 and fixed with screws 133 and 134, It is possible to prevent the position of the binding body 101 from moving away from the knee joint. When the binding body 101 is moved away from the knee joint, not only the treatment problem of the medical treatment room (not shown) for sewing the wound on the cartilage area but also the effect of the correction of the hair curling can be reduced. It is preferable to be located at a close position.

The positioning of the positioning openings 115 and 116 can be adjusted so that the height of the support blocks 131 and 132 can be adjusted so that the support blocks 131 and 132, So that the binding tool 100 can be always fixed to the same position.

The binding member 100 according to the present invention includes first to third screw through holes 103, 105 and 106 by dividing the fixing position of the screw for fixing the binding body 101 to the tibia 10, Three first screws 120 are fixed in the left and right direction on the upper portion of the cut bone portion 11 and two second screws 121 are fixed on the lower portion of the first screw 120 in the vertical direction, Even though the fixing force to the tibia 10 is improved and the positioning openings 115 and 116 are formed to have a height larger than the height of the support blocks 131 and 132 by fixing the four third screws 122 in the vertical direction, The tibia 10 can be firmly fixed.

FIG. 4 is a view showing a case in which an osteotomy portion, which is a cutting portion of a tibia, is cut obliquely in an embodiment of the present invention.

Referring to FIG. 4, when the osteotomy portion 11 is cut at a high height on the left side, the shape of the osteotomy portion 11 is distorted. Even in this case, there is no problem in the present invention. 4, the left support block 131 inserted into the left positioning aperture 115 is high and the right support block 132 inserted into the right positioning aperture 116 is fixed low, It can be easily coped with.

FIG. 5 shows a tie-hole 100 'for tibial proximal osteotomy according to another embodiment of the present invention, in which there is no right-side positioning opening and only a left-side positioning opening 115. It is possible to configure only the right positioning opening as opposed to Fig. The configuration of the present embodiment can be applied to the case where only one support block 131 is possible. Since only the right positioning aperture is provided and the remaining configuration is the same as that of the above-described embodiment, the same reference numerals are used and the explanation is omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be understood by those skilled in the art that many changes and modifications of the present invention can be made without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate modifications and changes, and equivalents thereof, should be regarded as within the scope of the present invention.
