Description
본 고안은 의료기기에 관한 것으로, 더욱 상세하게는 요추를 이루는 뼈들 사이에 삽입되어 그 뼈들의 간격을 유지시켜주는 요추고정구에 관한 것이다.The present invention relates to a medical device, and more particularly to a lumbar fixture that is inserted between the bones forming the lumbar spine to maintain the spacing of the bones.
일반적으로 요추, 즉 척추에 손상을 입은 환자는 요추를 이루는 각 뼈 사이의 간격이 좁아져서 각 뼈가 신경을 압박하므로 통증을 느끼며, 또한 거동을 마음대로 할 수 없게 된다. 이러한 환자에 대한 시술로는 요추를 이루는 뼈들 사이에 요추고정구를 삽입하여 그 뼈들 사이의 간격을 유지시켜 신경을 풀어주는 방법이 행해여져 왔다.In general, patients with a damaged lumbar spine, i.e., spinal cord, have narrowed spacing between the bones that make up the lumbar spine, so that each bone compresses nerves, so that the patient feels pain and cannot be able to move freely. As a procedure for such a patient, a method of releasing nerves by inserting a lumbar anchor between the bones constituting the lumbar spine and maintaining the gap between the bones has been performed.
이러한 종래의 요추고정구를 도 1에 도시하였다. 도면을 참조하면 종래의 요추고정구(1)의 몸체(3)에는 개구부(9)가 형성되어 있다.This conventional lumbar spine fixture is shown in FIG. 1. Referring to the drawings, the opening 9 is formed in the body 3 of the conventional lumbar spine 1.
상기 몸체(3)는 티타늄 등의 금속으로 이루어져 있으며, 별도의 수술용 기구(미도시)에 의해 요추를 이루는 뼈들 사이에 삽입되어 그 뼈들 사이의 간격을 유지시켜 준다. 그리고 이 몸체(3) 내에는 빈 공간부가 형성되어 있다.The body 3 is made of metal, such as titanium, is inserted between the bones forming the lumbar vertebrae by a separate surgical instrument (not shown) to maintain the spacing between the bones. In this body 3, an empty space portion is formed.
상기 개구부(9)는 상기 몸체(3) 내의 공간부를 몸체(3) 외부와 연통시키도록 몸체(3)의 상하전후좌우면에 각각 형성되어 있다. 이 개구부(9)는 상기 몸체(3)의 공간부 내에 신체융합을 촉진하는 뼈 이식물질을 채워넣기 위해 상기 몸체(3)에 형성된 것이며, 또한 신체 내의 영양분 등의 소통을 위하여 마련된 것이다.The openings 9 are formed on the upper, lower, front, rear, left and right surfaces of the body 3 so as to communicate the space inside the body 3 with the outside of the body 3. The opening 9 is formed in the body 3 to fill the bone graft material for promoting body fusion in the space of the body 3, and is provided for communication of nutrients and the like in the body.
상술한 구조를 가진 요추고정구를 요추를 이루는 뼈들 사이에 삽입하여 그 뼈들의 간격을 유지시키줌으로써 뼈들이 신경을 압박하지 않게 하는 것이다.The lumbar fixture having the above-described structure is inserted between the bones constituting the lumbar spine so as to maintain the spacing of the bones so that the bones do not compress the nerves.
그러나, 종래의 요추고정구는 시간의 경과나 환자의 움직에 따라 요추를 이루는 뼈들 사이로부터 돌출되거나 이탈되어 환자의 신경을 자극함으로써 고통을 유발하고 재삽입을 위하여는 다시 수술을 해야 하는 문제점이 있었고, 요추고정구의 이탈방지를 위해 별도의 고정술까지 시행하여야 하는 경우가 많아 의료비의 부담이 가중되는 문제점이 있었다.However, the conventional lumbar vertebral fixture protrudes or deviates from the bones constituting the lumbar vertebrae over time or as the patient moves, causing pain by stimulating the nerve of the patient, and having to undergo surgery for reinsertion. In order to prevent deviation of the lumbar fixture, a separate fixation procedure is often required, causing a burden of medical expenses.
본 고안은 상기한 바와 같은 제반 문제점을 해결하기 위하여 제안된 것으로, 그 목적은 요추고정구를 인위로 제거하기 전에는 요추고정구가 요추를 이루는 뼈들 사이로부터 이탈되거나 돌출되는 것을 방지할 수 있는 요추고정구를 제공함에 있다.The present invention has been proposed to solve the above-mentioned problems, the object is to provide a lumbar spine that can prevent the lumbar spine from deviating or protruding between the bones constituting the lumbar spine before removing the lumbar spine artificially Is in.

상기 몸체(10)를 계속 진입시켜 상기 몸체(10)를 최종적으로 안착시키고자 하는 위치(도 5에 도시된 위치)보다 약간 뒤에까지 삽입시켜 둔다. 이러한 상태에서, 다시 삽입방향과는 반대 방향인 도 4의 화살표(B) 방향으로 상기 몸체(10)를 잡아당긴다. 그러면, 상술한 바와 같이 상기 첨예부(21)가 상기 돌출홈(51)에 약간 경사지게 얹혀진 상태이고 또한 첨예부(21)의 끝단이 요추를 이루는 뼈(2)를 긁으면서 삽입되었으므로, 상기 도 4의 화살표(B) 방향으로 이동시키기 시작하는 처음 순간에는 상기 첨예부(21)의 끝단이 요추를 이루는 뼈(2)에 걸리게 된다.The body 10 continues to enter and is inserted until slightly behind the position where the body 10 is finally settled (position shown in FIG. 5). In this state, the body 10 is pulled again in the direction of arrow B of FIG. 4 which is opposite to the insertion direction. Then, as described above, the sharp portion 21 is slightly inclined to the protruding groove 51, and the tip of the sharp portion 21 is inserted while scratching the bone 2 constituting the lumbar spine. At the first moment when it starts to move in the direction of arrow B, the end of the sharp part 21 is caught by the bone 2 forming the lumbar spine.
그리고 계속하여 상기 몸체(10)를 잡아당기면 몸체(10)는 처음에 진입한 반대방향으로 이동하게 된다. 그러나 첨예부(21)는 그 끝단이 요추를 이루는 뼈(2)에 걸려 있으므로, 처음에 진입한 반대방향으로 이동되지 못하고 본체부(22)를 몸체(10)에 대해 회동시키면서 기립하게 된다. 이처럼 첨예부(22)가 기립될 때 그 첨예부(22)는 도 5에 실선으로 도시한 바와 같이 뼈속으로 삽입되게 된다.Then, if you continue to pull the body 10, the body 10 is moved in the opposite direction initially entered. However, since the sharp part 21 is hung on the bone 2 that forms the lumbar vertebrae, the sharp part 21 does not move in the opposite direction initially entered and stands while rotating the body part 22 with respect to the body 10. As such, when the sharp portion 22 stands up, the sharp portion 22 is inserted into the bone as shown by the solid line in FIG.
상술한 바와 같이 상기 네일(20)의 첨예부(22)가 요추를 이루는 뼈(2) 속으로 삽입됨으로써 상기 몸체(10)는 인위적인 조작이 가해지지 않는 한, 요추를 이루는 뼈(2)로부터 돌출되거나 이탈되지 않는다.As described above, the sharp portion 22 of the nail 20 is inserted into the lumbar spine 2 so that the body 10 protrudes from the lumbar spine 2 unless an artificial manipulation is applied. It does not go away or goes away.
한편, 본 실시예에서와 같이 상기 몸체(10)와 요추를 이루는 뼈(2)가 마주한 면에 다수의 돌출부(40)를 형성하여 두면, 상기 돌출부(40)와 요추를 이루는 뼈(2)와의 마찰로 인하여 상기 몸체(10)가 요추를 이루는 뼈(2)로부터 돌출되거나 이탈되는 것이 더욱 억제되는 것이다.On the other hand, as shown in the present embodiment, if a plurality of protrusions 40 are formed on the surface facing the body 10 and the lumbar spine 2, the protrusions 40 and the lumbar spine 2 It is further suppressed that the body 10 protrudes or deviates from the bone 2 constituting the lumbar vertebra due to friction.
그리고 도 6에 도시된 본 고안의 다른 실시예에서와 같이 돌출부(41)가 상기 몸체(10)의 길이방향, 즉 상기 몸체(10)가 요추를 이루는 뼈(2)들 사이로 삽입되는 방향으로 형성되어 있으면 상기 몸체(10)를 요추를 이루는 뼈(2)들 사이로 삽입시키거나 빼어낼 때 상기 돌출부(41)가 가이드 역할을 하여 상기 몸체(10)가 좌우방향, 즉 삽입시키거나 빼어 내는 방향의 직각방향으로 틀어지는 것을 방지할 수 있다.And as in another embodiment of the present invention shown in Figure 6 the protrusion 41 is formed in the longitudinal direction of the body 10, that is, the direction in which the body 10 is inserted between the bone (2) constituting the lumbar spine If the body 10 is inserted or withdrawn between the bones (2) constituting the lumbar spine, the protrusion 41 serves as a guide so that the body 10 in the left and right directions, that is, the direction of insertion or withdrawal The twist in the perpendicular direction can be prevented.
한편, 상기 요추고정구(100)를 요추를 이루는 뼈(2)들 사이로부터 분리하여 제거시킬 필요가 있을 때에는 수술기구(미도시)를 이용하여 그 뼈(2)들 사이의 간격을 상기 몸체(10)가 빠져 나올 수 있을 만큼 충분히 이격시킨 뒤에 상기몸체(10)를 빼어내면 되는 것이다.On the other hand, when it is necessary to remove the lumbar fixture 100 from between the bones (2) constituting the lumbar spine, the interval between the bones (2) using a surgical instrument (not shown) to the body (10) ) Is enough to leave the body 10 is to be pulled out.
한편, 본 실시예에서는 상기 몸체(10)의 상면에만 상기 네일(20)이 결합되어 있으나 여기에 한정하는 것은 아니며 상기 몸체(10)의 하면에도 상기 네일(20)이 결합될 수도 있다.Meanwhile, in the present embodiment, the nail 20 is coupled only to the upper surface of the body 10, but is not limited thereto. The nail 20 may also be coupled to the lower surface of the body 10.
이상에서와 같이 본 고안에 따른 요추고정구에 의하면, 시간이 경과하거나 환자의 움직임에 따라 요추고정구가 요추를 이루는 뼈들 사이로부터 돌출되거나 이탈되는 것을 방지할 수 있는 효과가 있다.As described above, according to the lumbar spine fixture according to the present invention, there is an effect of preventing the lumbar fixture from protruding or deviating from the bones constituting the lumbar vertebrae as time passes or the movement of the patient.
본 고안은 첨부된 도면에 도시된 일 실시예를 참고로 설명되었으나, 이는 예시적인 것이며, 당해 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 수 있을 것이다. 따라서 본 고안의 진정한 보호범위는 첨부된 청구범위에 의해서만 정해져야 할 것이다.The present invention has been described with reference to one embodiment shown in the accompanying drawings, which is illustrative, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom. .
