It shows the temperature meter for measuring.
다음은 상기한 본 고안의 작용 및 작동에 대해 살펴보기로 한다.Next, the operation and operation of the present invention described above will be described.
신체의 내강(100)에 암조직, 악성종양 등에 의한 협착부위가 발견되면, 삽입장치를 이용하여 본 고안의 스텐트를 통상의 방법으로 신체의 내강(100)에 삽입하여 자체 탄성으로 협착되는 병변부위(110)를 확장시키도록 하게 된다.When stenosis is found in the lumen 100 of the body due to cancer tissue, malignant tumor, etc., the lesion site is inserted into the lumen 100 of the body in a conventional manner by using an insertion apparatus and is stenosis by elasticity itself. To expand 110.
이때, 본 고안의 스텐트는 내부에 절연재(10)로 피복된 원통형 몸체(5)와, 그 외측 중앙에 절연재가 피복되지 않은 원통형의 도전몸체(15)가 이중구조를 이루고 있다.At this time, the stent of the present invention has a double structure of a cylindrical body 5 coated with an insulating material 10 therein, and a cylindrical conductive body 15 without an insulating material coated on its outer center.
따라서, 상기 본 고안의 스텐트는 절연재가 아닌 외측의 도전몸체(15)가 내강(100)의 병변부위에 밀착되어 확장시키므로 상기 병변 부위에서 미끄럼을 방지하여 설치위치를 일정하게 유지하게 된다.Therefore, since the stent of the present invention is not an insulating material, the outer conductive body 15 is in close contact with the lesion part of the lumen 100 and expands, thereby preventing slippage at the lesion part, thereby maintaining a constant installation position.
이와 같은 본 고안의 스텐트는 상기 도전몸체(15)에 연결된 와이어(31)를 고주파발생기(30)에 연결하고, 또 고주파발생기(30)의 다른 와이어(32)를 별도의 패드(35)에 연결하여 상기 패드는 신체 외부에 접촉시키게 된다.The stent of the present invention connects the wire 31 connected to the conductive body 15 to the high frequency generator 30, and also connects another wire 32 of the high frequency generator 30 to a separate pad 35. The pad is in contact with the outside of the body.

이때, 상기 절연재(10)로 피복된 원통형 몸체(5)가 접촉된 부위로는 고주파 공급이 차단되고, 오직 상기 도전몸체(15)가 접촉된 부위로만 고주파가 공급되어 이 부위의 병변부위만(110)을 소작하여 괴사시키게 되는 것이다.At this time, the high frequency supply is cut off to the site where the cylindrical body 5 covered with the insulating material 10 is in contact, and only the lesion site of this area is supplied due to the high frequency being supplied only to the area where the conductive body 15 is in contact. Cauterize 110) to necrosis.
또한, 본 고안은 온도측정기(40)에 의해 상기 도전몸체(15)의 온도를 확인할 수 있는데, 이러한 온도 감지에 따라 고주파 열 공급을 높게 또는 낮게 조절하므로 병변부위(110)의 괴사 정도를 조절할 수 있게 된다.In addition, the present invention can check the temperature of the conductive body 15 by the temperature measuring device 40, and adjust the degree of necrosis of the lesion site 110 by adjusting the high frequency heat supply high or low according to the temperature detection. Will be.
이와 같이 병변부위의 괴사가 완료되면 상기 도전몸체(15)에 연결된 와이어(31)를 잡아 당겨 인출하므로 본 고안의 스텐트만이 병변부위(110)를 확장 상태로 설치됨을 유지하게 되는 것이다.When necrosis of the lesion site is completed as described above, the wire 31 connected to the conductive body 15 is pulled out so that only the stent of the present invention is installed to maintain the lesion site 110 in an expanded state.
더우기, 상기와 같이 병변부위를 괴사시킨 경우에도 이 부위의 병변 부위가 재생되면서 다시 협착이 진행될 수 있는데, 이 경우 상기 본 고안의 스텐트는 절연재(10)가 피복된 원통형 몸체(5)와 그 외측의 도전몸체(15)가 이중구조를 이루고 있어 상기 협착 진행되는 병변부위가 몸체(5)의 전연부(10)에 의해 차단되어 몸체(5)의 공간부(3)를 통해 그 내측으로 삐져 나올수 없도록 차단하게 된다.Furthermore, even when necrosis of the lesion site as described above, the lesion site of this site can be regenerated and stenosis can proceed again. In this case, the stent of the present invention has a cylindrical body 5 coated with an insulating material 10 and its outside. The conductive body 15 of the dual structure is formed so that the lesion progressing the narrowing is blocked by the leading edge portion 10 of the body 5 can be protruded inward through the space portion 3 of the body 5 Will be blocked.
즉, 상기 이중구조를 갖는 본 고안의 스텐트에 의해 다시 협착진행되는 병변부위의 협착을 완전 차단하게 되는 것이다.That is, the stenosis of the present invention having the dual structure completely blocks the narrowing of the lesion site.
한편, 본 고안의 스텐트는 몸체(5)의 양측단 내경이 중앙부분보다 크게 형성하여 중앙부위의 외측에 요부(20)를 형성하고, 이 부위에 도전몸체(15)가 설치되도록 하므로서 전체적으로 일정한 직경을 갖도록 제공되어 신체의 내강에 삽입 설치가 용이하게 제공되고, 또한 상기 도전몸체(15)는 그 일측만이 몸체(5)에 연결되는 구조로서 부피의 신축이 용이하게 제공되어 삽입 설치작업을 우수하게 제공할 수 있게 되는 것이다.On the other hand, the stent of the present invention is formed in the inner diameter of both ends of the body 5 larger than the central portion to form the recessed portion 20 on the outer side of the central portion, the conductive body 15 is installed on this portion as a whole, a constant diameter It is provided so as to be easily inserted and installed in the lumen of the body, and the conductive body 15 is a structure that is connected only to one side of the body 5, the expansion and contraction of the volume is easily provided to excellent insertion installation work Will be able to provide.
또한, 본 고안의 스텐트는 와이어(2)를 엮는 형태를 다소 달리하도록 변경 실시할 수 있으나 이와 같은 단순한 스텐트의 구조 변경정도는 본 고안의 권리범위에 귀속됨을 밝혀둔다.In addition, the stent of the present invention can be modified to vary the shape of the wire 2 weave a little different, but the degree of structural change of such a simple stent is found to belong to the scope of the present invention.
이상에서 살펴본 바와 같이 본 고안의 고주파 열치료용 스텐트는 절연재가 피복된 몸체와 절연재가 피복되지 않은 도전몸체의 이중구조를 제공하므로서, 내강의 협착되는 병변부위를 확장시 그 설치상태를 확실히 유지하게 되고, 도전몸체에 의한 고주파 열로 병변 부위를 소작시켜 괴사시킴은 물론 상기 병변부위가 재생하여 다시 협착진행되는 것을 절연재가 피복된 몸체에 의해 완전 차단하므로서 사용상의 신뢰도를 극대화하는 효과를 갖는 것이다.As described above, the high-frequency heat treatment stent of the present invention provides a dual structure of a body coated with an insulating material and a conductive body not coated with an insulating material, so that the installation state is surely maintained when expanding the constricted lesion site of the lumen. In addition, by cauterizing the lesion area by high frequency heat by the conductive body, necrosis of the lesion area as well as the restoring and restoring of the lesion area by the body coated with the insulating material have the effect of maximizing reliability in use.
