Abstract

PURPOSE: A cervical spine anterior fixation device using pegs-adhered plate is provided, which locates a plate on operation part exactly and easily, lowers probability to be exposed to infection of patients by shortening surgery time, decreases the staff for the surgery, and simplifies or decreases surgery devices. CONSTITUTION: The cervical spine anterior fixation device using pegs-adhered plate comprises a plate(1), four screws(2), two pegs(3), four holes(4), two tappings(5) to adhere peg heads(7), and a hole(6) to see motion of bone graft inserted in a disc while fixing the plate on the cervical vertebral body. The plate(1) is located on surgery part using a subsidiary surgery device and the pegs(3) during the cervical spine anterior fixation surgery, and is fixed by penetrating the screws(2) through holes(4) of the plate(1). In this step, the pegs(3) attached on the plate(1) lead fixing location and direction of the plate(1) accurately before inserting screws, and help the screws(2) to be inserted without any other subsidiary apparatus.

Description

페그가 부착된 플레이트를 이용한 경추 전방 고정 기기{Anterior Cervical Plate with the Peg and Screw Fixation System}Anterior Cervical Plate with the Peg and Screw Fixation System

본 발명은 정형외과(orthopedics)와 신경외과(neurosurgery) 영역에서 경추 추간판 질환(cervical disc disease); 경추 디스크(cervical hernial disc), 경추성 척수증(cervial spondylosis myelopathy), 경추 골절(cervical fracture) 및 탈구(dislocation), 종양(tumor) 그리고 경추의 후만 변형(kyphotic deformity)의 치료 및 교정에 사용되는 경추 전방 삽입물로써 페그(peg)가 부착된 플레이트와 스크루에 관한 것이다.The present invention relates to cervical disc disease in the areas of orthopedics and neurosurgery; Cervical vertebrae used for the treatment and correction of cervical hernial discs, cervial spondylosis myelopathy, cervical fractures and dislocations, tumors and kyphotic deformity It relates to a plate and a screw to which a peg is attached as an anterior insert.

기존에 사용되는 경추 전방 삽입물들 중 플레이트와 스크루를 이용한 것은 페그가 부착되어 있지 않아 스크루와 수술 보조 기구만을 가지고 플레이트를 경추에 고정시키기 위해서는 많은 보조 인원과 장비가 필요하며, 수술 시간이 길어져 환자의 출혈이 과다해지고 감염의 기회가 높다. 또한 경추 추체에 플레이트를 비스듬하게 잘못 고정하는 경우가 빈번하게 발생하여 경추 전방 수술 후 신경 손상이나 생체역학(biomechanics)적인 불안정을 유발하고 있다.Among the conventional cervical spine inserts that are used in the past, the plate and the screw are not attached to the pegs, so it requires a lot of assistants and equipment to fix the plate to the cervical spine with only screws and surgical aids. The bleeding is excessive and there is a high chance of infection. In addition, the plate obliquely fixed to the cervical spine frequently occurs, causing nerve damage or biomechanics instability after anterior cervical spine surgery.

먼저 본 발명이 속한 경추 전방 내 고정 장치 중 플레이트와 스크루를 이용한 수술 과정을 다음과 같이 간략하게 설명할 수 있다. 먼저 수술 부위를 절개(incision)하여 경추 추체(cervical vertebral body)를 드러낸 후 손상된 디스크(disc)를 제거하고 그 자리에 골 이식물(bone graft)을 삽입한다. 그리고 스크루를 플레이트에 관통시켜 경추 추체에 고정한다. 그러나 플레이트를 경추 추체에 고정시키는 과정에서 스크루를 삽입하기 위해 플레이트를 정확히 시술 위치에 잡고 있기 힘들 뿐 아니라 고정 후 플레이트가 비스듬하게 고정되는 경우가 빈번하다.First, the surgical procedure using a plate and a screw in the anterior fixing device of the cervical spine to which the present invention belongs can be briefly described as follows. First, the surgical site is incision to reveal the cervical vertebral body, the damaged disc is removed, and a bone graft is inserted in place. The screw is then passed through the plate and fixed to the cervical spine. However, in order to insert the screw in the process of fixing the plate to the cervical vertebrae, it is often difficult to hold the plate in the correct position, and the plate is often fixed obliquely after the fixation.

본 발명은 위와 같은 경추 전방 수술 과정에 있어, 절개 후 경추 추체와 디스크가 확연히 구분되어 질 때 미리 페그가 들어갈 자리를 척추 추체에 뚫어 놓는다. 그리고 플레이트를 경추 추체에 고정시킬 때 플레이트에 부착된 페그를 이용하여 미리 뚫어 놓은 구멍에 집어넣어 위치시킨 후, 스크루를 이용하여 고정한다. 이처럼 본 발명은 플레이트에 페그를 장착함으로써 경추에 플레이트를 고정시 적은 수술 장비와 인원으로 플레이트를 쉽고 정확하게 시술 위치와 방향에 고정시킬 수 있게 한다.According to the present invention, when the cervical vertebral disc and the disc are clearly distinguished after the incision, the place where the peg enters is drilled in the spinal vertebra. When the plate is fixed to the cervical vertebrae, the plate is inserted into a hole previously drilled using a peg attached to the plate, and then fixed using a screw. As such, the present invention allows the plate to be easily and accurately fixed to the procedure position and direction with fewer surgical instruments and personnel when the plate is fixed to the cervical spine by mounting the peg on the plate.

이하, 첨부된 도면에 따라서 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings in detail as follows.

도 1은 본 발명에 의한 페그가 부착된 플레이트를 스크루를 사용하여 경추 추체(cervical vertebral body)에 부착한 모습을 예시한 그림이다.1 is a diagram illustrating a state in which a peg-attached plate according to the present invention is attached to a cervical vertebral body using a screw.

도 2에 명시한 바와 같이 본 발명은 플레이트(1)와 스크루(2) 그리고 페그(3)로 구성되어진다.As indicated in FIG. 2, the present invention consists of a plate 1, a screw 2 and a peg 3.

도 3에 나타낸 것처럼 플레이트(1)는 스크루(2)가 관통하기 위한 구멍(4)과 페그 헤드(7) 부착을 위한 태핑(tapping)(5), 그리고 플레이트를 경추 추체에 고정시키는 동안 디스크(disc)에 삽입되어 있는 골 이식물(bone graft)의 움직임을 주시하기 위한 구멍(6)을 가진다.As shown in FIG. 3, the plate 1 comprises a hole 4 through which the screw 2 penetrates, a tapping 5 for attaching the peg head 7, and a disk during fixing the plate to the cervical vertebrae. It has a hole 6 for watching the movement of the bone graft inserted into the disc.

도 4에 예시한 바와 같이, 페그(3)는 척추 추체에 삽입되는 실린더 형태의 페그 바디(8)와 플레이트(1)에 부착되는 페그 헤드(7)를 가지고 있으며, 페그 헤드(7)는 볼트(bolt)로 되어있어 필요에 따라 부착과 탈착이 가능하다.As illustrated in FIG. 4, the peg 3 has a cylindrical peg body 8 inserted into the spinal vertebra and a peg head 7 attached to the plate 1, the peg head 7 having a bolt. (bolt), it is possible to attach and detach as needed.

도 5는 페그(3)가 부착된 플레이트의 모습을 측단면도로 나타내었다.5 is a side cross-sectional view of the plate to which the peg 3 is attached.

도 6,7에서는 도 3에서의 상세도 'A-A'와 'B-B' 각각에 대해서 스크루 관통을 위한 구멍(4)과 페그 부착을 위한 태핑(5)을 측단면으로 나타내었다.In FIGS. 6 and 7, holes 4 for screw penetration and tapping 5 for peg attachment are shown in side cross-sections for the detailed views 'A-A' and 'B-B' in FIG. 3, respectively.

경추 전방 수술에 있어 플레이트(1)는 수술 보조 기구와 페그(3)를 이용하여 경추 추체에 위치되어지며, 플레이트의 구멍(4)에 스크루(2)를 관통시켜 고정된다. 이 과정에서 플레이트(1)에 부착된 페그(3)는 스크루를 삽입하기 전에 플레이트(1)의 고정 위치와 방향을 정확히 잡아주며 보조 기구 없이도 스크루(2)를 삽입할 수 있도록 도와주는 역할을 한다.In the anterior cervical spine, the plate 1 is positioned on the cervical vertebral body using a surgical aid and a peg 3, and is fixed by passing a screw 2 through the hole 4 of the plate. In this process, the peg 3 attached to the plate 1 accurately holds the fixing position and direction of the plate 1 before inserting the screw, and helps to insert the screw 2 without the aid. .

상기와 같은 구성과 작용으로 인해 본 발명은 경추 수술에 있어 플레이트를 쉽고 정확하게 시술 부위에 위치시킬 수 있고, 수술 시간의 단축으로 환자가 감염에 노출될 확률을 낮추며, 수술 인원을 감소시키고, 수술 기구들을 단순화하거나 줄여주는 효과를 거둘 수 있게 한다.Due to the configuration and operation as described above, the present invention can easily and accurately place the plate in the surgical site in the cervical spine operation, the operation time is reduced by reducing the probability of the patient exposed to infection, reducing the number of surgery, surgical instruments It can be used to simplify or reduce them.
