본 고안은 척추 삽입물(spine insert)에 관한 것으로, 보다 상세하게는 척추간에 삽입이 용이하며, 생체 적합성이 좋은 척추 삽입물에 관한 것이다.The present invention relates to a spine insert, and more particularly to a spinal insert that is easy to insert between the spine, biocompatible.

척추 삽입물은 퇴행성 척추 협착증이나 교통사고 등으로 척추가 회복 불능인 상태일때 등과 같이 척추에 삽입되어 사용되는 것이다. 퇴행성 척추 협착증의 예를 들어 살펴보면 다음과 같다.Spinal inserts are to be inserted into the spine, such as when the spine is unrecoverable due to degenerative spinal stenosis or traffic accidents. An example of degenerative spinal stenosis is as follows.

인체가 노화되어 감에 따라 척추에도 퇴행성 변화가 일어나서, 척추간의 간격이 가까워지게 되며, 이와 같은 변화에 의해 극돌기 또는 황색인대가 척추 신경 또는 척추 신경과 연결되는 신경 돌기를 압박하는 것을 척추 협착증이라고 한다.As the human body ages, degenerative changes occur in the spine, and the spacing between the vertebrae becomes closer. Spinal stenosis is called compression of the spinous process or the yellow ligament, which is connected to the spinal nerve or the spinal nerve. .

척추 협착증의 치료 방법으로는 약물에 의한 치료, 물리 치료, 수술에 의한 치료 등이 있다. 이들 중 수술에 의한 치료는 타치료 방법에 의해 치료가 안될 때 사용되는 것으로, 상기 신경을 압박하는 뼈와 조직들을 제거하고, 이로 인해 척추가 불안정해 질 것을 대비하여 나사못으로 척추를 고정하는 수술법이 일반적으로 알려져 있다. 그러나 상기한 수술 방법은 광범위한 뼈와 조직의 제거를 하여야 하므로, 전신 마취가 필요하고, 긴 수술 시간 및 수술 후 긴 회복 기간이 요구된다. 따라서 기력이 약한 노인들은 수술을 할 수 없는 경우가 많고, 합병증 기타 이유로 만족할 만한 수술의 효과를 얻지 못하는 경우도 자주 발생하는 문제점이 있으며, 수술 비용도 많이 드는 문제점이 있었다.Treatment of spinal stenosis includes treatment with drugs, physical therapy, surgery. Among these, surgical treatment is used when it is not treated by other treatment methods, and it removes bones and tissues that compress the nerves and fixes the spine with screws in preparation for instability of the spine. Generally known. However, the above-described surgical method requires extensive removal of bone and tissue, so general anesthesia is required, and a long operation time and a long recovery period after surgery are required. Therefore, elderly people who have weak energy often do not operate, there is a problem that often occurs when complications and other reasons do not obtain a satisfactory effect, there was a problem that costs a lot of surgery.

이러한 문제 대한 해결책의 하나로, 척추 사이에 척추 삽입물을 삽입하는 방법이 있는 데, 종래의 척추 삽입물은 시술이 어려운 반면에 쉽게 이탈되는 문제점이 있으며, 사용되는 재료가 금속 혹은 합성수지이므로 장기간 착용시 인체에 손상을 쉽게 입힌다는 단점이 있었다. As a solution to this problem, there is a method of inserting a spinal insert between the vertebrae, the conventional spinal inserts are difficult to perform, while the problem of easy separation, and because the material used is metal or synthetic resin for long-term wear It was easy to damage.

이러한 문제점을 해소하기 위해서 인체 혹은 동물의 뼈를 추출하여 이를 이 용하여 척추 삽입물을 형성하는 방법이 알려져 있다. 그러나, 제한된 재료를 가지고 원하는 형상을 얻는 것이 쉽지 않으며, 이 또한, 종래의 형상을 그대로 사용하여 시술의 어려움 및 시술 후 안정성이 떨어진다는 문제점은 그대로 내포하고 있다.In order to solve this problem, a method of extracting a bone of a human body or an animal and using the same to form a spinal insert is known. However, it is not easy to obtain a desired shape with a limited material, and also, the problem of difficulty of the procedure and poor stability after the procedure by using the conventional shape as it is.

본 고안은 상기와 같은 문제점을 해결하고자 안출 된 것으로서, 시술이 용이할 뿐만 아니라, 시술 후에도 이탈이 쉽게 되지 않는 척추 삽입물을 제공함을 그 목적으로 한다. The present invention has been made to solve the above problems, and the object of the present invention is to provide a spinal insert that is not only easy to perform the procedure but also easy to detach after the procedure.

본 고안의 또 다른 목적은 인체에 적합한 재료를 사용함에도, 원하는 형상을 얻을 수 있는 구조의 척추 삽입물을 제공하는 데 있다.Still another object of the present invention is to provide a spinal insert having a structure capable of obtaining a desired shape, even using materials suitable for the human body.

본 고안은 상술한 바와 같은 목적을 달성하기 위하여, 척추뼈의 사이에 삽입되는 척추 삽입물에 있어서, 상측 척추뼈에 접하는 상면; 상기 상면의 반대측에 형성된 하면; 및 상기 상면과 상기 하면을 연결하는 양측면;을 포함하며, 상기 상면은 척추의 하측면의 형상에 적합하도록 곡면으로 형성된 것을 특징으로 하는 척추 삽입물을 제공한다. 따라서, 척추뼈 사이에 삽입이 용이할 뿐만 아니라, 삽입 후에 보다 견고하게 고정되도록 한다.The present invention, in order to achieve the object as described above, in the spinal insert inserted between the vertebra, the upper surface in contact with the upper vertebrae; A lower surface formed on an opposite side of the upper surface; And both side surfaces connecting the upper surface and the lower surface, wherein the upper surface provides a spinal insert, which is formed in a curved surface so as to conform to the shape of the lower surface of the spine. Thus, not only the insertion between the vertebrae is easy, but also more firmly fixed after insertion.

여기서, 상기 상면에는 톱니 형상의 상측 요철이 형성되며, 상기 하면에는 톱니 형상의 하측 요철이 형성된 것이 바람직하다. 또한, 상기 상측 요철 및/또는 상기 하측 요철은, 상기 척추 삽입물이 삽입되는 방향의 전방 경사면 및 반대 방향 의 후방 경사면으로 형성되며, 상기 후방 경사면이 상기 전방 경사면 보다 더 가파르게 형성된 것이 효과적이다. 따라서, 삽입은 용이함에 반해서 이탈은 어렵게 함으로써, 시술은 용이하나 시술 후 쉽게 이탈되는 것은 방지한다.Here, it is preferable that serrated upper irregularities are formed on the upper surface, and serrated lower irregularities are formed on the lower surface. In addition, the upper unevenness and / or the lower unevenness are formed of a front inclined surface in a direction in which the spinal insert is inserted and a rear inclined surface in an opposite direction, and the rear inclined surface is more steeply formed than the front inclined surface. Therefore, the insertion is easy, but the separation is difficult, so that the procedure is easy, but is not easily separated after the procedure.

그리고, 상기 상측 요철 및/또는 상기 하측 요철의 끝단은 모따기 되어 형성되는 것이 바람직하다. 이는 강성이 인체의 뼈와 유사한 재질로 형성될 경우, 끝단이 쉽게 부러지며, 부러진 끝단이 인체에 손상을 입히는 것을 방지하기 위해서이다.따라서, 요철이 쉽게 부러지는 것을 방지할 수 있을 뿐만 아니라, 파편들이 생기지 않아서 다른 조직 등에 손상을 가하는 것도 방지할 수 있다.And, the end of the upper unevenness and / or the lower unevenness is preferably formed by chamfering. This is because when the rigidity is formed of a material similar to the bone of the human body, the tip is easily broken and the broken tip is prevented from damaging the human body. Thus, not only the irregularities can be easily prevented from breaking, but also the fragments It can also prevent damage to other tissues.

또한, 상기 척추 삽입물은 다수로 분할되어 결합되며, 상기 척추 삽입물은 상기 분할된 부분들을 관통하는 핀으로 결합된 것이 효과적이다. 따라서, 생물의 뼈와 같은 재료의 취득이 어려운 것으로도 원하는 크기의 뼈 삽입물을 형성할 수 있다.In addition, the spinal insert is divided into a plurality of joints, it is effective that the spinal insert is joined by a pin penetrating the divided parts. Therefore, even if it is difficult to obtain a material such as a bone of an organism, a bone insert of a desired size can be formed.

그리고, 상기 상면과 상기 하면을 관통하는 관통공이 형성된 것이 바람직하다. 따라서 관통공에 척추 뼈와 척추 삽입물의 결합을 촉진할 수 있는 재료을 삽입할 수 있어, 보다 빨리 고정되도록 할 수 있다.And, it is preferable that the through hole penetrating the upper surface and the lower surface is formed. Therefore, it is possible to insert a material that promotes the coupling of the vertebral bone and the vertebral insert into the through hole, so that it can be fixed faster.

이하, 첨부도면을 참조하여 본 고안의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

다만, 본 고안을 설명함에 있어서, 공지된 기능 혹은 구성에 대해 구체적인 설명이 본 고안의 요지를 흩트리지 않도록 하기 위하여 생략하기로 한다.However, in describing the present invention, a detailed description of a known function or configuration will be omitted so as not to disturb the gist of the present invention.

도 1은 본 고안의 제 1 실시예의 척추 삽입물의 사시도이다.1 is a perspective view of a spinal insert of a first embodiment of the present invention.

제 1 실시예의 척추 삽입물은 상측 척추뼈에 접하는 상면(100)과, 상면(100) 의 반대측에 형성된 하면(200)과, 상면(100)과 하면(200)을 연결하는 양측면(300)과, 삽입되는 전방에 형성된 전면(400)과, 전면(400)의 반대측에 형성된 후면(500)을 포함한다.Spinal insert of the first embodiment is the upper surface 100 in contact with the upper vertebra, the lower surface 200 formed on the opposite side of the upper surface 100, both side surfaces 300 connecting the upper surface 100 and the lower surface 200, It includes a front surface 400 formed in the front to be inserted, and a rear surface 500 formed on the opposite side of the front surface 400.

상면(100)에는 톱니 형상의 상측 요철(110)이 형성되며, 하면(200)에는 톱니 형상의 하측 요철(210)이 형성된다. 상측 요철(110) 및 하측 요철(210)은, 삽입되는 방향, 즉 전면(400), 측으로는 전방 경사면(111, 211)이 형성되고, 후면(500) 측으로는 후방 경사면(112, 212)이 형성된다. 후방 경사면(112, 212)은 전방 경사면(111, 212) 보다 더 가파르게 형성되는 것이 바람직하다. 즉, 도 2와 같이, 전방 경사면(111, 211)은 45도 정도로 형성되고, 후방 경사면(112, 212)은 45도 보다 급하게 형성된다. 이는, 삽입할 때에는 전방 경사면으로 인해서 미끄러져 쉽게 삽입되고, 삽입 후에는 후방 경사면(112, 212)에 쉽게 빠지는 것을 방지하기 위해서이다.The upper surface 100 is formed with a sawtooth upper unevenness 110, the lower surface 200 is formed with a serrated lower unevenness 210. The upper concave-convex 110 and the lower concave-convex 210 are formed in the direction in which they are inserted, that is, the front inclined surfaces 111 and 211 on the front side 400 and the rear inclined surfaces 112 and 212 on the rear side 500 side. Is formed. The rear inclined surfaces 112 and 212 are preferably formed more steeply than the front inclined surfaces 111 and 212. That is, as shown in FIG. 2, the front inclined surfaces 111 and 211 are formed at about 45 degrees, and the rear inclined surfaces 112 and 212 are formed more rapidly than 45 degrees. This is to prevent slipping easily due to the front inclined surface when inserted, and to easily fall into the rear inclined surfaces 112 and 212 after insertion.

상측 요철(110) 및 하측 요철(210)의 끝단은 모따기(113, 213) 되어 형성된다. 이는 강성이 인체의 뼈와 유사한 재질로 형성될 경우, 끝단이 쉽게 부러지며, 부러진 끝단이 인체에 손상을 입히는 것을 방지하기 위해서이다. Ends of the upper unevenness 110 and the lower unevenness 210 are formed by chamfering 113 and 213. This is because when the rigidity is formed of a material similar to the bones of the human body, the ends are easily broken and the broken ends are prevented from damaging the human body.

상면은 척추의 하측면의 형상에 적합하도록 곡면으로 형성된다. 즉, 상면(100)은 도 2에 도시된 곡선(130)을 따라 형성된다. 곡선(130)은 척추 삽입물입 삽입되는 척추의 하측면의 곡선과 동일한 것이 바람직하다. 따라서, 삽입이 용이할 뿐만아니라, 삽입 후에도 상면의 상측 요철(110)이 모두 척추의 하측면과 접하여 보다 견고하게 고정되는 효과가 있다.The upper surface is formed into a curved surface to fit the shape of the lower surface of the spine. That is, the upper surface 100 is formed along the curve 130 shown in FIG. The curve 130 is preferably the same as the curve of the lower side of the spine being inserted. Therefore, not only the insertion is easy, but also the upper concave-convex 110 on the upper surface is in contact with the lower surface of the spine, there is an effect that is more firmly fixed.

측면(300)에는 시술시 사용되는 집게가 파지되기 용이하도록 파지홈(310)이 요입되어 형성된다. The side surface 300 is formed by gripping grooves 310 to facilitate grip of the forceps used during the procedure.

도 3은 도 1의 상면측에서 바라본 평면도이다.3 is a plan view seen from the upper surface side of FIG.

도시된 바와 같이, 후면(500)과 측면(300) 사이의 모서리(510)가 모따기되어 형성된다. 이는 모서리(510)가 돌출되면 시술 시 끝단이 부러져 그 끝단이 인체의 다른 조직을 자극하거나 손상하는 것을 방지하기 위한 것이다. 모서리(510)는 곡면으로 형성될 수도 있다.As shown, the edge 510 between the back surface 500 and the side surface 300 is chamfered. This is to prevent the tip is broken when the edge 510 is protruded during the procedure to stimulate or damage other tissues of the human body. The edge 510 may be formed in a curved surface.

도 4는 도 1의 분리 사시도이다.4 is an exploded perspective view of FIG. 1.

도시된 바와 같이, 척추 삽입물은 다수의 부분(11~13)으로 분할되어 결합된 다. 즉, 양측면(30)과 나란하게 3개로 분할된다. 이는 합성수지 혹은 금속재질로 형성하지 않고 인체의 뼈와 유사한 생물체의 뼈에서 추출할 경우 원하는 크기를 일체로 추출하는 것이 쉽지 않다. 따라서, 다수의 부분으로 분할하여 작은 조각으로 추출하여 결합함으로써, 원재료보다 큰 형상의 척추 삽입물을 형성할 수 있다. 각각의 부분은 핀삽입공(600) 관통되어 형성된다. 핀삽입공(600)에는 핀(700)이 삽입되어 각각의 부분(11, 12, 13)을 하나의 척추 삽입물(10)로 결합한다. 핀(700)은 핀삽입공(600)에 억지끼워 맞춤할 수 있는 직경으로 형성되며, 각각의 부분(11, 12, 13)과 동일한 재질로 형성되는 것이 바람직하다.As shown, the spinal insert is divided into multiple parts 11-13 and joined. That is, it is divided into three in parallel with both side surfaces (30). It is not easy to extract the desired size integrally when extracting from bones of organisms similar to human bones without forming synthetic resins or metal materials. Thus, by dividing into a plurality of parts to extract and combine into small pieces, it is possible to form a spinal insert of a shape larger than the raw material. Each portion is formed through the pin insertion hole 600. The pin 700 is inserted into the pin insertion hole 600 to couple the portions 11, 12, and 13 into one spinal insert 10. The pin 700 is formed to have a diameter that can be fitted to the pin insertion hole 600, it is preferably formed of the same material as each of the parts (11, 12, 13).

상기와 같이, 본 고안의 제 1 실시예의 척추 삽입물은, 먼저, 상면(100)이 척추의 하측면의 형상을 따라서 곡면으로 형성됨으로써, 삽입이 용이할 뿐만 아니라, 삽입후 보다 견고하게 고정된다.As described above, the spinal insert of the first embodiment of the present invention, first, the upper surface 100 is formed in a curved surface along the shape of the lower surface of the spine, not only easy to insert, but more firmly fixed after insertion.

또한, 후방 경사면(112, 212)이 전방 경사면(111, 212)에 비해서 급경사로 형성됨으로써, 삽입을 용이하게 하고, 이탈은 어렵게 하는 장점이 있다.In addition, since the rear inclined surfaces 112 and 212 are formed to have a steep slope as compared with the front inclined surfaces 111 and 212, there is an advantage in that insertion is facilitated and separation is difficult.

또한, 별도의 다수의 부분으로 결합함으로써, 인체의 뼈와 유사한 재질로도 큰 크기의 척추 삽입물을 형성할 수 있는 장점이 있다.In addition, by combining into a plurality of separate parts, there is an advantage that can form a spinal insert of a large size even from a material similar to the bone of the human body.

도 5는 본 고안의 제 2 실시예의 구조를 도시한 사시도이다.5 is a perspective view showing the structure of a second embodiment of the present invention.

제 2 실시예의 척추삽입물은 목 척추 부위에 삽입되는 것으로써 전체적인 형상이 약간 상이하나, 중앙에 상면(1100)과 하면(1200)을 관통한 관통공(1800)이 형성된 점과, 분리되는 방향이 상면과 나란하게 된다는 점 및 핀(1700)이 상하로 삽입된다는 점을 제외하고 제 1 실시예와 동일하다. 관통공(1800)에는 척추에 삽입 전에 뼈와 본딩이 촉진되는 물질을 삽입한다. 이러한 물질은 이미 많이 알려져 있으므로 상세한 설명을 생략하며, 이러한 물질은 본 고안의 권리범위와 무관하다.The spinal insert of the second embodiment has a slightly different overall shape by being inserted into the neck vertebra, but a through hole 1800 penetrating the upper surface 1100 and the lower surface 1200 is formed at the center thereof, and the direction of separation is different. It is the same as the first embodiment except that it is parallel with the top surface and the pin 1700 is inserted up and down. The through hole 1800 inserts a substance for promoting bone and bonding before insertion into the spine. Since many of these materials are already known, a detailed description thereof will be omitted, and such materials are irrelevant to the scope of the present invention.

따라서, 척추 삽입물과 척추 뼈 사이를 빨리 고정할 수 있어, 환자의 시술 후 회복을 더욱 빨리 할 수 있다는 장점이 있다.Therefore, there is an advantage that can be fixed quickly between the spinal insert and the vertebral bone, it is possible to recover more quickly after the procedure of the patient.

이상에서는 본 고안의 바람직한 실시예를 예시적으로 설명하였으나, 본 고안의 범위는 이와 같은 특정 실시예에만 한정되는것은 아니며, 실용신안등록청구범위에 기재된 범주내에서 적절하게 변경 가능한 것이다. In the above described a preferred embodiment of the present invention by way of example, the scope of the present invention is not limited only to this specific embodiment, it can be appropriately changed within the scope described in the utility model registration claims.

이상에서 살펴본 바와 같은 본 고안의 실시예에 의하면 다음과 같은 사항을 포함하는 다양한 효과를 기대할 수 있다. 다만, 본 고안이 하기와 같은 효과를 모두 발휘해야 성립되는 것은 아니다.According to the embodiment of the present invention as described above it can be expected a variety of effects, including the following. However, the present invention is not achieved only if all of the following effects.

먼저, 본 고안의 척추 삽입물은, 상면이 척추의 하측면의 형상을 따라서 곡면으로 형성됨으로써, 삽입이 용이할 뿐만 아니라, 삽입 후 보다 견고하게 고정된다.First, the spinal insert of the present invention, the upper surface is formed in a curved surface along the shape of the lower surface of the spine, not only easy to insert, but more firmly fixed after insertion.

또한, 상면 및 하면에 형성된 요철의 후방 경사면이 전방 경사면에 비해서 급경사로 형성됨으로써, 삽입을 용이하게 하고, 이탈은 어렵게 하는 장점이 있다.In addition, since the rear inclined surfaces of the uneven surfaces formed on the upper and lower surfaces are formed to have a steep slope as compared with the front inclined surface, the insertion and the detachment are difficult.

또한, 별도의 다수의 부분으로 결합함으로써, 인체의 뼈와 유사한 재질로도 큰 크기의 척추 삽입물을 형성할 수 있는 장점이 있다.In addition, by combining into a plurality of separate parts, there is an advantage that can form a spinal insert of a large size even from a material similar to the bone of the human body.

그리고, 뼈의 결합을 촉진하는 물질을 수용할 수 있도록 상면과, 하면을 관통하는 관통공이 형성되어 척추 삽입물과 척추가 더욱 빨리 결합되도록 한다.In addition, through-holes penetrating the upper and lower surfaces are formed to accommodate the material for promoting the bonding of the bones so that the spinal insert and the vertebrae are coupled more quickly.
