Description

추간체 고정 보형재{Artificial Disk for Anterior Lumbar Interbody Fusion}Intervertebral Fixation for Intervertebral Discs {Artificial Disk for Anterior Lumbar Interbody Fusion}

본 발명은 추간체 고정 보형재에 관한 것이다. 특히, 본 발명은 척추 사이에 보형재가 견고하게 끼워지고 고정될 수 있도록 몸체의 상, 하부에 뿔을 여러 개 형성하여 이 뿔이 주축이 되어 추체 사이에서 보형재가 기울어지거나, 미끄러지거나 또는 탈락되지 않도록 한 추간체 고정 보형재에 관한 것이다. The present invention relates to an intervertebral fixation prosthesis. In particular, the present invention forms a plurality of horns on the upper and lower parts of the body so that the prosthesis can be firmly fitted and fixed between the vertebrae so that the horn is the main axis so that the prosthetic member does not tilt, slip or fall out between the vertebrae. It relates to an intervertebral fixed prosthesis.

추간체 고정용 보형재는 인공 디스크(disk, 추간판)로서, 인체의 척추를 구성하는 추간판이 퇴행, 퇴행에 의한 질환, 노화, 사고 등으로 본래의 기능을 수행하지 못할 때 디스크를 적출하고 그 적출된 위치에 삽입되어 디스크의 기능을 수행하게 한 것이다. The intervertebral fixation prosthesis is an artificial disk (disc), and when the intervertebral disc constituting the human spine fails to perform its original function due to degenerative, degenerative disease, aging, accident, etc. It is inserted in place to perform the functions of the disc.

보통 추간체 고정 보형재는 중공형으로서, 그 내부에는 본칩(bone chip)이 삽입되고 이 본칩이 재생되어 상, 하 추체(body)와 일체됨으로써 디스크의 역할을 담당할 수 있게 된다. Usually, the intervertebral fixation prosthesis is hollow, and a bone chip is inserted therein, and the bone chip is regenerated so as to be integrated with the upper and lower bodies, thereby serving as a disk.

종래에는 보형재가 척추 사이에 삽입된 후 과도한 움직임이 발생하더라도 이탈되거나 미끄러지지 않도록 하기 위하여, 도 1에 도시된 바와 같이 몸체(2)의 상, 하부에 여러 개의 뾰족한 스파이크(spike)(3)를 돌출 성형하여 추체 사이에 삽입된 보형재(1)의 스파이크(3)가 피골질에 파고들어가 움직이지 않고 고정되게 하였다.Conventionally, in order to prevent deviation or slipping even after excessive movement occurs after the prosthesis is inserted between the vertebrae, as shown in FIG. Spikes 3 of the prosthesis 1 inserted between the vertebrae were molded into the cortical bone so that they were fixed without moving.

상기 스파이크(3)는 라운드와 뾰족한 모양의 중간 정도로 가공되어 있기 때문에 내구성이 우수하여 추간판(디스크)이 제거된 자리에 삽입하면, 척추의 피질골에 적절하게 삽입 고정되며, 보형재(1)가 미끄러지는 현상을 방지하고 활착이 원활하게 이루어질 수 있게 하는 것이다.Since the spikes 3 are processed in the middle of a round and pointed shape, they are excellent in durability, and when inserted into the place where the intervertebral disc (disc) is removed, the spike 3 is properly inserted and fixed to the cortical bone of the spine, and the prosthesis 1 slips. Is to prevent the phenomenon and to facilitate the smooth operation.

한편, 위와 같은 보형재(1)도 시술 후 척추의 익스텐션(extension)이나 축방향 회전(axial rotation)이 발생할 경우 보형재(1)가 미끄러지거나 탈락되는 현상이 종종 발생하게 된다. On the other hand, the prosthesis 1, as described above, often occurs when the extension (axial) or axial rotation (spinning) of the spine after the procedure that the prosthesis (1) slips or falls off.

따라서, 상기한 현상을 방지하기 위하여 현재는 도 2에 도시된 바와 같이 보형재(1)와 페디클 스크류(pedicle screw)(4)를 병행하여 시술하는 것이 보통이다. Therefore, in order to prevent the above phenomenon, as shown in FIG. 2, the implant 1 and the pedicle screw 4 are usually performed in parallel.

그러나 위와 같은 수술은 비교적 어렵고 큰 수술에 속한다. 특히, 이러한 수술은 환자의 비용 부담을 높일 뿐만 아니라 수술 시간이 길고, 집도의와 수술에 참여하는 관계자들의 피로도를 높인다. 페디클 스크류(4)를 시술하는 방법은 이 기술이 속한 분야에서 일반적으로 알려져 있으므로 상세한 설명은 생략한다. However, the above surgery is relatively difficult and belongs to the big surgery. In particular, such surgery not only increases the patient's cost burden, but also lengthens the operation time and increases the fatigue of the physician and those involved in the operation. Since the method of operating the pedicle screw 4 is generally known in the art, detailed description thereof will be omitted.

결국, 보형재(1)의 관건은 수술 후 견고하게 고정되고 탈락되지 않도록 함에 있는데, 도 2와 같은 수술이 이루어진다 하더라도 피시술자가 과도하게 움직일 경우 보형재(1)가 미끄러지거나 탈락할 수 있는 염려를 전혀 배제할 수 없다. 도 2에서, 도면부호 3a 및 3b는 척추 추체(body)이다. After all, the key to the prosthesis (1) is to be firmly fixed and prevented from falling after the operation, even if the operation is performed as shown in Figure 2 there is a fear that the implant (1) can slip or fall if the subject is excessively moved. It cannot be excluded at all. In Fig. 2, reference numerals 3a and 3b denote the vertebral body.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 척추의 익스텐션(extension)이나 축방향 회전(axial rotation)에도 피질골로부터 보형재가 탈락되지 않게 하는 추간체 고정 보형재를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide an intervertebral fixation prosthesis that prevents the prosthesis from falling off the cortical bone even in the extension or axial rotation of the spine. .

위 목적은 중공형 몸체; 및 상기 몸체의 상부 및/또는 하부의 전방 선단부 및/또는 후방 선단부에 뾰족하게 돌출 형성되는 뿔; 을 포함하여 이루어지는 것을 특징으로 하는 본 발명에 의해 달성된다. The above object is a hollow body; And a horn protruding sharply at the front and / or rear ends of the upper and / or lower portions of the body; It is achieved by the present invention characterized in that it comprises a.

상기 몸체는 상, 하부에 뾰족하게 여러 개의 스파이크가 돌출 형성되고, 상기 뿔이 상기 스파이크보다 더 크고 높게 돌출 형성되도록 구성함이 바람직하다. The body is preferably configured so that a plurality of spikes protrudingly formed on the upper and lower portions, and the horns protrude larger and higher than the spikes.

상기 뿔은 상기 몸체의 상부 또는 하부에서 각각 서로 대칭되게 쌍으로 형성되도록 함이 바람직하다.The horns are preferably formed in pairs symmetrically with each other at the top or bottom of the body.

위와 같이 이루어지는 본 발명은 여러 개의 뿔이 추체에 깊이 삽입되어 보형재가 견고한 고정상태를 유지하게 하여 보형재의 탈락을 저지하고 과도한 힘으로부터 보형재와 추체의 견고한 고정상태를 유지시킴으로써, 보형재의 미끄럼현상 또는 탈락현상을 방지할 수 있게 하는 효과를 갖는다. The present invention made as described above by inserting a number of horns deeply into the vertebrae to keep the prosthesis is a fixed fixed state to prevent the fall of the prosthesis and to maintain a rigid fixed state of the prosthetic member and the vertebral from excessive force, the sliding phenomenon or It has the effect of preventing the dropout phenomenon.

본 발명의 구성 및 작용을 첨부된 도 3과 도 6을 참조하여 설명하면 다음과 같다. Referring to the configuration and operation of the present invention with reference to Figures 3 and 6 as follows.

먼저, 도 3에 도시된 바와 같이 본 발명에 따른 추간체 고정 보형재(110)는, 중공형 몸체(101)의 상, 하부면에 다수 개의 뾰족한 스파이크(102)가 돌출 형성되어 있으며, 상기한 스파이크(102)는 몸체(101)의 각각 좌, 우측 상, 하부면에 여러 개가 연계 형성되어 스파이크군(102a)을 형성하게 된다. First, as shown in FIG. 3, the intervertebral fixing prosthesis 110 according to the present invention has a plurality of sharp spikes 102 protruding from and formed on the upper and lower surfaces of the hollow body 101. Spikes 102 are formed on the left, right upper, lower surfaces of the body 101 in conjunction with each other to form a spike group (102a).

여기서, 본 발명은 상기 스파이크(102) 중 적어도 어느 하나를 선정하여 그 위치에 스파이크(102)보다 크고 뾰족한 뿔(103)을 도 3과 같이 성형하는 바, 상기 뿔(103)의 위치를 선정하는 방식은 본 발명에 의해서 한정되지 않으므로 무작위로 선정하여 뿔(103)을 성형하여도 무방하다.Herein, the present invention selects at least one of the spikes 102 and forms a larger and pointed horn 103 than the spikes 102 as shown in FIG. 3 at the position thereof, thereby selecting the position of the horns 103. Since the method is not limited by the present invention, the horns 103 may be molded at random.

그러나, 상기 뿔(103)의 형성위치는 도 3에 도시된 바와 같이 몸체(101)의 전, 후방 선단부에 각각 형성되도록 하여 어느 하나의 뿔(103)과 다른 뿔(103)이 일정 거리 이격되게 형성되도록 함이 바람직하며, 도시된 바와 같이 몸체(101)의 상, 하부의 좌, 우측에 분리 형성된 스파이크군(102a)의 서로 인접한 위치에 뿔(103)이 성형되도록 하는 것이 바람직하다.However, the formation position of the horn 103 is to be formed in the front and rear tip portions of the body 101, as shown in Figure 3 so that any one horn 103 and the other horn 103 is spaced a certain distance apart It is preferable to be formed, it is preferable that the horn 103 is formed in the position adjacent to each other of the spike group (102a) formed separately on the left, right, upper and lower portions of the body 101 as shown.

즉, 몸체(101)의 상, 하부에 형성되는 뿔(103)은 서로 일정거리 이격되도록 성형하고, 이때, 가로방향과 세로방향으로 동일선상에 배열될 수 있도록 뿔(103)을 형성함으로써, 가로방향으로 힘이 작용할 때, 가로방향으로 이격 형성된 뿔(103a,103b)(103c, 103d)이 균일하게 힘을 분산시켜 고정력을 확보할 수 있게 되는 것이며, 세로방향으로 힘이 작용할 때, 세로방향으로 이격 형성된 뿔(103a, 103d)(103b, 103c)이 균일하게 힘을 분산시켜 고정력을 확보할 수 있게 되는 것이 다.That is, the horns 103 formed on the upper and lower portions of the body 101 are formed to be spaced apart from each other by a predetermined distance, and at this time, by forming the horns 103 to be arranged on the same line in the horizontal and vertical directions, When the force acts in the direction, the horns 103a, 103b, 103c, 103d, which are spaced apart in the horizontal direction, can uniformly distribute the force to secure a fixed force, and when the force acts in the longitudinal direction, Horns 103a and 103d spaced apart (103b, 103c) is to be able to secure a fixed force by uniformly dispersing the force.

아울러, 도 4는 본 발명에 따른 추간체 고정 보형재(110)가 추체의 피골질에 삽입된 상태를 도시한 도면으로서, 추체(104)의 익스텐션(extension)이나 축방향 회전(axial rotation)이 발생할 경우, 서로 이격된 상태로 형성된 뿔(103)이 추체의 피골질(104a)에 깊게 삽입된 상태이므로 몸체(101)의 어느 한쪽으로 힘이 편중될 때 이에 대항하여 몸체(101)를 지지하고 고정력이 확보될 수 있게 하는 것이다.In addition, Figure 4 is a view showing a state in which the intervertebral fixing prosthesis 110 is inserted into the cortical bone of the vertebral body, the extension or axial rotation of the vertebral body 104 is When it occurs, the horns 103 formed to be spaced apart from each other are deeply inserted into the cortical bone 104a of the vertebra, so when the force is biased to either side of the body 101, the body 101 is supported against it. It is to ensure a fixed force.

따라서, 상기 뿔(103)은, 상기 몸체(101)의 상, 하부면의 좌, 우측에 각각 한 쌍이 대칭된 위치에서 돌출형성되게 함으로써, 상, 하부면의 대칭적 위치에 있는 뿔(103)이 서로 대응되게 힘을 분산시키거나 지지할 수 있게 되는 것이다.Accordingly, the horns 103 are formed at the symmetrical positions of the upper and lower surfaces by allowing the pair to protrude from the symmetrical positions on the left and right sides of the upper and lower surfaces of the body 101, respectively. The forces can be distributed or supported correspondingly to each other.

그리고, 도시된 바와 같이 상기 스파이크(102)보다 뿔(103)이 피골질에 더 깊게 삽입됨을 알 수 있으며, 몸체(101)의 상, 하부면에 형성된 뿔(103)은 서로 일정거리 이격된 위치에서 돌출 형성되어 있으므로, 서로 대칭적인 위치에 형성되어 좌우상하로 편중되게 작용하는 힘을 뿔(103)들이 서로 분산하여 완화시키므로, 견고한 고정력이 유지될 수 있게 되는 것이다.And, as shown, it can be seen that the horn 103 is inserted deeper into the cortex than the spike 102, the horn 103 formed on the upper, lower surfaces of the body 101 are spaced apart from each other a certain distance Since the protrusions are formed in a symmetrical position to each other, the horns 103 are distributed to alleviate the forces acting symmetrically to the left and right, up and down, so that a rigid fixing force can be maintained.
