Description

척추용 인공 삽입물 {An implant for vertebra}Spinal prosthesis {An implant for vertebra}

본 발명은 척추용 인공 삽입물에 관한 것으로서, 특히 척추의 디스크 관련 질병을 치료하기 위해 척추 사이의 손상된 디스크를 대신하여 이식되는 척추용 인공 삽입물에 관한 것이다.
The present invention relates to a spinal prosthesis, and more particularly to a spinal prosthesis which is implanted in place of a damaged disc between the spine to treat a disc related disease of the spine.

척추 삽입물은 퇴행성 척추 협착증이나 교통사고 등으로 척추가 회복 불능인 상태일 때 손상된 디스크 대신 척추 사이에 삽입되어 사용되는 것이다.Spinal inserts are used between spinal vertebrae instead of damaged discs when the spine is unrecoverable due to degenerative spinal stenosis or traffic accidents.

퇴행성 척추 협착증의 예를 들어 살펴보면 다음과 같다.An example of degenerative spinal stenosis is as follows.

인체가 노화되어 감에 따라 척추에도 퇴행성 변화가 일어나서, 척추 간의 간격이 가까워지게 되며, 이와 같은 변화에 의해 극돌기 또는 황색 인대가 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 gap between the vertebrae becomes closer, which causes spinal stenosis to compress the spinous process or the yellow ligaments that connect the spinal nerve or the spinal nerve. .

척추 협착증의 치료 방법으로는 약물에 의한 치료, 물리 치료, 수술에 의한 치료 등이 있다. Treatment of spinal stenosis includes treatment with drugs, physical therapy, surgery.

이들 중 수술에 의한 치료는 다른 치료 방법에 의해 치료가 불가능할 때 사용되는 것으로, 상기 신경을 압박하는 뼈와 조직들을 제거하고, 이로 인해 척추가 불안정해 질 것을 대비하여 나사못으로 척추를 고정하는 수술법이 일반적으로 알려져 있다. Among these, surgical treatment is used when it is impossible to treat 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.

그러나 상기한 수술 방법은 광범위한 뼈와 조직의 제거를 하여야 하므로, 전신 마취가 필요하고, 긴 수술 시간 및 수술 후 긴 회복 기간이 요구된다. 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.

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.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 문제에 대한 해결책의 하나로, 척추 사이에 척추 삽입물을 삽입하는 방법이 있다.One solution to this problem is to insert a spinal insert between the vertebrae.

도 1은 종래의 척추용 인공 삽입물을 나타낸 사시도이다.1 is a perspective view showing a conventional spinal prosthesis.

도 1에 도시된 바와 같이 종래의 척추용 인공 삽입물은, 대략 육면체 형상으로 형성되며, 가운데에 뼈 생성물질이 주입되는 중공이 구비된다.As shown in FIG. 1, the conventional spinal prosthesis is formed in a substantially hexahedral shape and has a hollow in which a bone generating material is injected.

이러한 종래의 척추용 인공 삽입물은 손상된 척추 디스크를 제거한 대신에 이식되며, 수술 후 척추 마디에 뼈가 재생되면서 마디를 굳혀주게 된다.Such a conventional spinal prosthesis is implanted instead of removing a damaged spinal disc, and the bone is regenerated in the spinal node after surgery to harden the node.

그러나 종래의 척추용 인공 삽입물은 척추의 단면방향 중앙에 안착되는데, 척추의 단면방향 중앙은 밀도가 약하기 때문에 골 침식(bony invasion)의 발생 위험이 증가하게 되는 문제점이 있었다.
However, the conventional spinal prosthesis is seated in the center of the cross-sectional direction of the spine, because the density of the cross-section of the spine is weak, there is a problem that increases the risk of bony invasion.

도 2 내지 도 6에 도시된 바와 같이 본 발명의 실시예에 따른 척추용 인공 삽입물(100)은 티타늄 또는 카본이 포함되는 재질로 이루어진 몸체부(110)와 날개부(120)를 포함한다.As shown in FIGS. 2 to 6, the artificial implant 100 for a spine according to the embodiment of the present invention includes a body 110 and a wing 120 made of a material containing titanium or carbon.

상기 몸체부(110)는 척추(20) 사이에 디스크를 대신하여 이식되며, 주로 목 부위의 경추 치료에 사용된다.The body 110 is implanted in place of the disk between the vertebrae 20, and is mainly used for cervical spine treatment of the neck area.

상기 몸체부(110)는 대략 육면체 형상으로 형성되고, 척추(20)의 신경 방향 일단의 좌우 너비가 타단의 좌우 너비보다 작게 형성된다.The body portion 110 is formed in a substantially hexahedral shape, the left and right width of one end of the nerve direction of the spine 20 is formed smaller than the left and right width of the other end.

즉, 도 6에 도시된 바와 같이, 상기 몸체부(110)는 평면에서 바라볼 때 신경통로(40) 방향에서 멀어질수록 좌우 너비가 점점 넓어지는 사다리꼴 형상으로 형성된다.That is, as shown in Figure 6, the body portion 110 is formed in a trapezoidal shape that gradually widens the left and right widths as the distance from the neural passage 40 in the plan view.

또한, 도 3에 도시된 바와 같이 상기 몸체부(110)의 상면은 높이가 신경통로(40) 방향으로 점점 높아지는 곡면으로 형성된다.In addition, as shown in FIG. 3, the upper surface of the body part 110 is formed as a curved surface whose height is gradually increased in the direction of the neural passage 40.

이러한 상기 몸체부(110)는 시술시 도 5 및 도 6에 도시된 바와 같이 척추(20)의 단면방향 중심부(21)에 배치된다.The body portion 110 is disposed in the cross-sectional direction central portion 21 of the spine 20 as shown in Figure 5 and 6 during the procedure.

즉, 도 6에 도시된 바와 같이 평면에서 바라볼 때, 상기 몸체부(110)는 척추(20)의 중심부(21)에 배치된다.That is, as shown in FIG. 6, when viewed in plan, the body part 110 is disposed at the central portion 21 of the spine 20.

또한, 상기 몸체부(110)에는 상하 개방된 2개의 중공부(111)가 형성된다.In addition, the body portion 110 is formed with two hollow portions 111 open up and down.

상기 중공부(111)는 좌우 대칭되게 형성되고, 시술시 내부에 뼈 생성물질이 채워진다.The hollow portion 111 is formed to be symmetrical left and right, the bone formation material is filled in during the procedure.

뼈 생성물질은 시술 후 경추의 마디에 뼈가 재생되는 것을 유도하여 경추 마디 사이를 굳히기 위한 것이다.The bone formation substance is intended to induce bone regeneration in the nodes of the cervical spine after the procedure, thereby to harden between the nodes of the cervical spine.

또한, 상기 몸체부(110)에는 시술시 시술기구(30)가 삽입되는 연결공(112)이 형성된다.In addition, the body portion 110 is formed with a connection hole 112 is inserted into the surgical instrument 30 during the procedure.

상기 연결공(112)은 원형 형상이며, 상기 몸체부(110)의 폭 방향으로 개방 형성된다.The connection hole 112 has a circular shape, and is open in the width direction of the body portion 110.

또한, 상기 몸체부(110)의 상하면에는 끝이 날카로운 다수개의 미끄럼방지돌기(113)가 형성된다.In addition, the upper and lower surfaces of the body portion 110 is formed with a plurality of anti-slip projections 113 having sharp ends.

상기 미끄럼방지돌기(113)는 도 2에 도시된 바와 같이 원뿔 형상으로 형성된다,The anti-slip projection 113 is formed in a conical shape, as shown in Figure 2,

물론, 경우에 따라 상기 미끄럼방지돌기(113)는 가로 방향으로 길게 연결되면서 세로 방향으로 연속적으로 울퉁불퉁하게 형성된 톱니 형상으로 형성될 수도 있다.Of course, in some cases, the anti-slip protrusion 113 may be formed in a sawtooth shape that is continuously bumpy in the vertical direction while being connected in the horizontal direction.
