Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bone plate assembly having a tension means,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bone plate assembly having a tension means and a method of assembling the bone plate, and more particularly, to a bone plate assembly having a tension plate And a method of assembling the bone plate assembly.

Bone plates are fastening means used to fix bone fragments inside human and animal bodies. These bone plates are placed across the bone fragments and support, and the fractured bone is secured by securing each bone fragment and support and bone plate through bone screws.

Since the bone fragments in the human body or animal body have various shapes, in order to firmly connect the bone fragments with the support, it is necessary to be able to arrange the bone screws of various sizes, not one standard, on the bone plate at various angles.

However, existing bone plates all have a problem in that it is difficult to fasten bone screws of various sizes on a bone plate at a set angle by forming a screw thread arbitrarily.

Therefore, there is a disadvantage in that it is not easy to effectively and stably fracture the fractured bone using the bone plate.

More specifically, the first step S110 may include a first-stage (S111) to a first-third step (S113).

In the first step S111, the inner wall of the through hole H of the bone plate 110 is inserted into the bone plate 120 so as to give a tension corresponding to the fastening direction to the bone screw 120 fastened to the bone plate 110. [ A plurality of cutouts 111 and protrusions 112 may be alternately formed along the circumferential direction at a predetermined depth toward the inner wall.

Here, the bone plate 110 may be formed such that the through holes H are rounded or tapered from above to below.

Next, at step S120, threading is formed from at least a portion of the first region S1, which is an initial portion of the through hole H, to the second region S2 below the initial portion of the bone plate 110 .

Next, in a first step S113, at least one of the through holes H of the bone plate 110 is tilted with a predetermined angle of inclination of the threads on the first region S1 and the second region S2 As shown in FIG.

Here, the first-first step S111 to the first-third step S113 are described as being sequentially performed, but the present invention is not limited thereto and can be sufficiently performed in a non-sequential manner.

In a second step S120, a bone screw 120 having a head 121 of a predetermined shape and fastened to the through hole H through reverse rotation or normal rotation is prepared. More specifically, the second step S120 may include steps 2-1 (S121) to 2-2 (S122).

First, in the second-first step S121, the screw may be fastened through the first region S1 and the second region S2 on the through hole H, and in the second-2step S122, The head portion 121 can press the incision portion 111 and the protrusion 112 by pressing the inclined portion of the bone screw 120.
