본 고안은 간질환자의 수술전 간질병소를 확인하는데 사용하는 뇌심부 전극에 관한 것이다.The present invention relates to a deep brain electrode used to identify preoperative epilepsy lesions in patients with epilepsy.

일반적으로, 간질수술을 하기 위해서는 간질병소의 위치 규명이 필요한데, 통상적인 방법으로는 두피전극을 이용한 뇌파기록을 토대로 이를 규명하였으나, 이러한 경우에는 그 한계가 있어 간질병소의 정확한 위치를 아는데 어려움이 있었다.In general, epilepsy surgery requires the identification of the location of epilepsy lesions, the conventional method was based on EEG recording using the scalp electrode, but in this case there is a limit to know the exact location of the epilepsy disease.

이런 관계로, 간질병소를 정확하게 규명할 수 없게 되어 간질수술 그 자체가 불가능 할 뿐만 아니라, 부정확한 방법에 의존하여 수술할때는 정상적인 뇌세포의 손실을 감수해야만 하였다.In this regard, epileptic lesions could not be precisely identified, and epilepsy surgery itself was not possible, and it was necessary to bear the loss of normal brain cells when operating in an incorrect manner.

이러한 문제점을 해결하기 위하여 여러가지 전극을 사용하여 직접 뇌에서 이상뇌파를 찾아내는 방법을 사용하고 있는 바, 간질의 많은 원인이 뇌내의 망상계에서 발생하므로, 이 망상계의 뇌파를 측정하는데에는 도면 제2도에서 보는 바와 같은 뇌심부 전극을 사용하였다.In order to solve this problem, a method of directly detecting abnormal brain waves in the brain using various electrodes is used. Since many causes of epilepsy occur in the reticular system in the brain, it is necessary to measure the brain waves of this network. A deep brain electrode was used as shown in the figure.

그러나 이 방법은 뇌심부 전극이 부드러운 튜-브로 되어 있기 때문에 뇌내 목표정지에 삽입하는데 어려운 점이 있었고, 모든 뇌정위수술기구에 사용되지 못하는 문제점과, 축심부재(11')와 접속되는 미세선(13')이 통과하는 통공(14')을 형성시키기에는 상당한 기술상의 문제점이 있었다.However, this method has a difficulty in inserting into the target stop in the brain because the deep core electrode is a soft tube, the problem that can not be used in all the stereotactic surgical instruments, and the fine lines (13) connected to the axial member (11 ') There was a significant technical problem in forming a through hole 14 'through which') passed.

또한, 뇌심부 전극은 그 지름이 대략 2 - 3㎜이므로, 시술과정에서 연질튜브를 뇌내에 삽입하고, 연질튜브 내측통공에 축심부재(11')를 다시 삽입하는 과정이 원활하지 못하였다In addition, since the diameter of the deep core electrode is about 2 to 3 mm, the process of inserting the soft tube into the brain and inserting the axial member 11 'back into the soft tube inner hole during the procedure was not smooth.

따라서, 본 고안은 상술한 바와 같은 종래의 제반 문제점을 감안하여 안출된 것으로, 플레이트를 다수개 배열하고, 그 내측으로 미세선이 권선되게한 전극축을 위치되게 하여 에폭시 수지로 밀봉한 뇌심부 전극을 제공함을 그 목적으로 한다.Accordingly, the present invention was conceived in view of the above-mentioned conventional problems, and arranged a plurality of plates, and placed the electrode shaft where the fine lines were wound inwardly so that the brain core electrode sealed with epoxy resin was placed. The purpose is to provide.

이하, 첨부된 도면을 참조하여 본 고안의 목적을 달성하기 위한 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the technical configuration for achieving the object of the present invention.

도면 제1도는 본 고안의 단면 사시도를 나타낸것으로 전기저항이 적은 플레이트(12)를 일정간격을 두고 배열하여 테프론 코팅된 스텐레스 재질의 전극축(11)을 그 내측에 삽입한다.1 is a cross-sectional perspective view of the present invention, and the plate 12 having a low electric resistance is arranged at a predetermined interval to insert an electrode shaft 11 of Teflon-coated stainless steel material into the inside thereof.

그리고, 각각의 플레이트(12)에서 접속되는 미세선(13)을 인출하여 상기 전극축(11)에 권선되게 하였다.And the fine wire 13 connected in each plate 12 was taken out, and it is made to wind up on the said electrode shaft 11.

또한, 상기의 전극축(11)과 미세선(13)에 한선씩 인출하여 별도 구비하게 되는 장비와의 연결이 가능토록 하되, 플레이트(12)와 전극축(11)의 위치고정을 위해 에폭시수지(14)를 충진되게 한 것이다.In addition, the electrode shaft 11 and the fine wire 13 to be drawn out by one line to be connected to the equipment to be provided separately, but the epoxy resin for fixing the position of the plate 12 and the electrode shaft 11 (14) was filled.

이와 같이 구성된 본 고안의 작용 및 효과는 다음과 같다.The operation and effects of the present invention configured as described above are as follows.

간질환자의 간질수술내지는 간질병소 확인을 위하여 뇌속에 이상전파 탐침용 뇌심부 전극(10)을 삽입하게 되는데, 이상뇌파는 삽입된 뇌심부 전극(10)의 각각의 플레이트(12)에서 점지되어 미세선(13)을 따라 별도 연결된 감시모니터(미도시함)에 특정파형으로 표시케 된다.Epilepsy surgery of the epilepsy patient is inserted into the brain deep electrode electrode 10 for abnormal radio wave probe to confirm the epileptic lesion, the abnormal brain wave is pointed at each plate 12 of the inserted deep brain electrode 10 is fine A specific waveform is displayed on a separate monitoring monitor (not shown) along the line 13.

이러한 과정에서 본 고안의 뇌심부 전극(10)은 금속에폭시수지(14)로 충진된 관계로 어느정도 경도를 유지할 수 있으므로, 뇌정위 기구를 사용한 시술에서 다른 튜-브 가이드를 사용할 필요가 없어 손쉽게 뇌내 삽입시술이 가능할 뿐아니라, 유연성도 지니고 있어 뇌내를 통과하여 주위의 혈관과 접할때 미끌리는 기능이 있어 치명적인 혈관손상 및 혈종형성을 피할 수 있게 된다.In this process, since the deep brain electrode 10 of the present invention is filled with the metal epoxy resin 14, the hardness can be maintained to some extent, so that it is not necessary to use another tubing guide in the procedure using the brain stereotactic device, and easily In addition to the insertion procedure, it also has the flexibility to penetrate the inner blood vessels in contact with the surrounding blood vessels, so as to avoid fatal blood vessel damage and hematoma formation.

한편, 뇌심부 전극(10)을 스텐레스 재질의 관으로된 지지대에 고정시키면, 이상신호 없이 일정수준으로 뇌파를 기록할 수 있게 되고, 발작시에도 이상신호없이 간질병소를 찾아낼 수 있도록 기록이 양호하게 된다.On the other hand, if the brain core electrode 10 is fixed to the support made of stainless steel tube, it is possible to record the EEG to a certain level without an abnormal signal, the record is good so that the epilepsy lesions can be found without abnormal signal during seizures Done.

또한, 뇌심부 전극과 지지대 사이를 점착제로 고정시키면, 외부와 완전차단되므로 뇌적수액의 누수나 감염의 위험없이 안전하게 간질병소를 찾아낼 수 있게 된 것이다.In addition, by fixing the adhesive between the deep core electrode and the support with the adhesive, it is completely blocked from the outside, it is possible to safely find the interstitial lesion without the risk of leakage or infection of cerebrospinal fluid.

여기에서 뇌심부 전극(10)의 각 플레이트(12)는 각 접점마다 뇌파를 찾아낼 수 있게 되므로 간질병소의 위치와 깊이에 관계없이 검색이 가능하여, 잘 배열된 위치대로 전극들이 삽입된다면 간질병소의 3차원적인 확인 뿐만 아니라 발작시 그 발작의 전파경로를 3차원으로 규명할 수 있어 간질수술을 위한 정확한 정보를 얻어낼 수 있게 되었다.Here, each plate 12 of the deep core electrode 10 is able to find the EEG at each contact point, so it is possible to search irrespective of the position and depth of the epileptic lesion. In addition to dimensional confirmation, the propagation path of the seizure can be identified in three dimensions during seizures, thereby obtaining accurate information for epilepsy surgery.

이상에서 본 바와 같이 본 고안은 간질수술환자의 간질병소 진달을 위하여 뇌내에 삽입하는 뇌심부전극을, 일정경도를 지니게 하여 삽입이 용이하며, 뇌내의 부작용으로 인한 의료사고를 미연에 방지할 수 있게된 고안인 것이다.As can be seen from the above, the present invention facilitates insertion of a deep core electrode inserted into the brain for epileptic progression of epileptic patients with a certain hardness, and prevents medical accidents due to side effects in the brain. It is a devised design.
