본 고안은 흉부, 예컨대 심장, 폐 또는 늑골에 삽입되는 카테타에 관한 것이다.The present invention relates to a catheter inserted into the chest, such as the heart, lungs or ribs.

현재 사용되는 흉부용카테타는 실리콘 수지로 제조되어 너무 유연해서 자체로 흉벽의 각층속으로 삽입되지 않는다.Currently used thoracic catheters are made of silicone resin and are so flexible that they do not insert themselves into each layer of the chest wall.

따라서, 종전의 카테타를 흉벽에 삽입하려면 환자의 피부를 절개한 후 피하조직과 근육층을 켈리로 잡아당겨 구멍을 뚫어 흉벽의 각층 조직을 분리 확장시켜 통로를 만든다음 켈리로 카테타를 집어서 통로를 통해 흉강에 밀어넣어 카테타가 삽입된다.Therefore, in order to insert a conventional catheter into the chest wall, the patient's skin is incised and the subcutaneous tissue and muscle layer are pulled with kelly to drill holes to separate and expand the corneal tissues of the chest wall to create a passage. The catheter is inserted by pushing it into the chest cavity.

이러한 시술은 피부를 절개하고 흉벽에 통로를 만든 후 한손으로는 켈리를 잡아서 흉벽의 근육등의 조직을 벌리고 다른 손으로는 카테타가 잡혀 있는 켈리를 흉강에 밀어넣어 이어진다.This procedure is made by cutting the skin and making a passage in the chest wall, holding Kelly with one hand to open the muscles of the chest wall, and pushing Kelly with the catheter into the chest cavity with the other hand.

종래의 카테타를 흉강에 삽입하는 이러한 방법은 켈리와 같은 도구를 사용해야 하고 흉벽의 각층 조직이 많이 손상되며 출혈이 있어 수술이 매우 힘들고, 더욱이 흉벽에 통로를 만들 때 흉벽이 손상되어 흉강내의 수술부위가 오염되어 기흉이 없는 단순한 혈흉이나 농흉의 경우에도 인위적인 기흉이 겹치게 된다.This method of inserting a conventional catheter into the chest cavity requires the use of a tool such as Kelly, which damages the various layers of the tissues of the chest wall and bleeds, making the operation very difficult. Contaminated, simple pneumothorax or emphysema without pneumothorax also causes artificial pneumothorax to overlap.

또한 흉벽의 각층 조직을 충분히 분리 시키고 확장시켜야 하기 때문에 피부 절개도 길어진다.In addition, the skin incision is lengthened because the tissues of the chest wall must be sufficiently separated and expanded.

본 고안의 목적은 상기와 같은 종래의 단점을 없애기 위하여 선단부에 구멍을 가지는 카테타에 선단부에 예리한 칼날이 돌출된 메스를 삽입하여 흉부에 간단히 삽입되는 흉부삽입용 카테타를 제공하고자 하는 것이다.It is an object of the present invention to provide a catheter for chest insertion simply inserted into the chest by inserting a scalpel with a sharp blade protruding from the tip to a catheter having a hole in the tip to eliminate the above disadvantages.

본 고안을 첨부된 도면을 참조하여 하기에 설명한다.The present invention will be described below with reference to the accompanying drawings.

제1도에는 본 고안의 카테타와 메스가 사시도로서 도시되는데, 카테타(1)는 직경이 대략 0.8㎝이고 길이가 35㎝내지 40㎝의 실리콘수지 튜브이다.Figure 1 shows the catheter and scalpel of the present invention as a perspective view, the catheter 1 is a silicone resin tube of approximately 0.8cm in diameter and 35cm to 40cm in length.

카테타(1)의 선단부(2)에는 구멍(3)이 형성되고 선단부(2)의 후방에는 상부구멍(4)과 하부구멍(5)의 형성되어 있다.A hole 3 is formed in the tip portion 2 of the catheter 1, and an upper hole 4 and a lower hole 5 are formed behind the tip portion 2.

또한, 카테타(1)의 선단부(2)의 내면 둘레부에는 단턱(16)을 일체로 형성하고 카테타(1)에는 선단부(2)로부터 길이를 나타내는 눈금(6)이 표시되어 있다.Moreover, the step 16 is integrally formed in the inner peripheral part of the front end part 2 of the catheter 1, and the scale 6 which shows the length from the front end part 2 is displayed on the catheter 1.

메스(10)는 카테타(1)의 내부에 삽입되면 스텐레스와 같은 금속제로 제조되고 길이는 카테타(1)보다 약간 길다.When the scalpel 10 is inserted into the catheter 1, the scalpel 10 is made of metal such as stainless steel, and the length is slightly longer than that of the catheter 1.

메스(10)의 선단부(11)에는 칼날(12)을 형성하고 칼날(12)의 후방에 단턱(16')을 형성하며 메스(10)의 후단부(13)에는 손잡이(14)가 형성되어 있다.A blade 12 is formed at the front end portion 11 of the scalpel 10, a step 16 ′ is formed at the rear of the blade 12, and a handle 14 is formed at the rear end 13 of the scalpel 10. have.

제2도에는 본 고안의 카테타(1)에 메스(10)가 삽입된 상태로 단면도로 도시된다.Figure 2 is shown in cross-sectional view with the scalpel 10 inserted into the catheter 1 of the present invention.

이러한 상태의 카테타(1)를 흉부에 삽입하려면 카테타(1)의 구멍(3) 밖으로 돌출된 메스(10)이 칼날(12)을 피부에 누르면 피부는 칼날(12)에 의해 절개되는데, 이때, 칼날(12)의 단턱(16)이 카테타(1) 내면의 단턱(16)에 걸리게 되어 칼날(12)을 더 이상 카테타(1) 구멍(3) 밖으로 나오지 않은 상태에서, 메스(10)의 손잡이(14)를 더욱 누르면 메스(10)의 칼날(12)은 흉벽에 통로를 만들며 진입하여 카테타(1)는 서서히 흉강내로 밀려 들어간다.In order to insert the catheter 1 in this state to the chest, the scalpel 10 protruding out of the hole 3 of the catheter 1 presses the blade 12 to the skin, and the skin is cut by the blade 12. The handle of the scalpel 10, with the step 16 of the blade 12 being caught by the step 16 of the inner surface of the catheter 1 so that the blade 12 no longer comes out of the catheter 1 hole 3. Pressing (14) further, the blade 12 of the scalpel 10 enters the chest wall and enters, and the catheter 1 is gradually pushed into the chest cavity.

메스(10)의 칼날(12)은 흉부 피부와 흉벽의 각층 조직을 절개하여 짧은 시간내에 카테타(1)를 흉강에 삽입시킬수 있게 한다. 이때 카테타(1)의 눈금(6)을 측정하여 카테타의 삽입 깊이를 확인할 수 있다. 카테타(1)가 흉강에 삽입된 후에는 카테타(1)로부터 메스(10)를 빼내면 삽입 수술은 끝난다. 그 후에는 카테타(1)를 도시되지 않은 튜브에 커넥터로 연결하여 흉강내의 공기, 피, 고름 또는 체액을 뽑아낼 수 있으며, 그리고, 카테타(1)는 실리콘 수지재의 튜브로, X-ray촬영시 나타나지 않아 흉강에 삽입된 카테타(1)의 위치 확인을 위하여 카테타(1)의 내면에 선을 표시하였다.The blade 12 of the scalpel 10 cuts the stratum corneum and the stratum corneum of the chest wall to allow the catheter 1 to be inserted into the chest cavity in a short time. At this time, it is possible to check the insertion depth of the catheter by measuring the scale 6 of the catheter 1. After the catheter 1 is inserted into the chest cavity, the scalpel 10 is removed from the catheter 1 and the insertion operation is finished. After that, the catheter 1 can be connected to a tube (not shown) with a connector to extract air, blood, pus or body fluid in the chest cavity, and the catheter 1 is a silicone resin tube, which is used for X-ray imaging. The line was marked on the inner surface of the catheter 1 to confirm the location of the catheter 1 inserted into the chest cavity.

상기와 같이 구성된 본 고안의 카테타를 사용하여 시술하면 종래와 같이 흉벽의 근육등의 조직을 분리 확장하지 않아서 피부절개시 미량의 출혈외에는 출혈이 전혀 없고 흉강내의 피나 고름이 흘러나와 술야를 더럽히지 않아서 시술과정이 깨끗해지는 장점이 있으며, 또한 시술부위인 흉벽 조직에 큰 손상을 주지 않고 공기가 흉강에 들어가지 않아서 인위적인 기흉이 생기지 않는 효과가 있다.When the procedure is performed using the catheter of the present invention configured as described above, tissues such as muscles of the chest wall are not separated and expanded as in the prior art. The procedure has the advantage of being clean, and also does not cause significant damage to the chest wall tissue, which is the surgical site, and the air does not enter the chest cavity so that artificial pneumothorax does not occur.
