이러한 가이드 도관(1)은, 도 5에 잘 도시된 바와 같이, 상기 유두부의 입구를 관통하여 상기 담도 내에 배치되는 제1도관부(11)와 상기 유두부를 기준으로 하여 상기 제1도관부(11)와 반대측에 위치하는 제2도관부(12)를 포함하여 이루어진다. 여기서, 상기 제2도관부(12)는 상기 유두부의 입구측에 배치되는 중심부를 사이에 두고 상기 제1도관부(11)와 반대측에 위치함으로써 상기 십이지장 내에 배치된다. This guide conduit 1, as is well illustrated in FIG. 5, penetrates through the entrance of the nipple portion and is disposed in the biliary tract 11 and the nipple portion based on the first conduit portion 11 It comprises a second conduit portion 12 located on the opposite side. Here, the second conduit portion 12 is disposed in the duodenum by being located on the opposite side to the first conduit portion 11 with a central portion disposed at the entrance side of the nipple portion therebetween.
본 발명에 의하면, 하나의 벌룬이 하나의 도관을 감싸는 종래기술과는 달리, 상기 제1도관부(11)에 상기 끼임방지용 벌룬(2)이 결합되고, 제2도관부(12)에 상기 확장용 벌룬(3)이 결합된다. According to the present invention, unlike the prior art in which one balloon wraps one conduit, the balloon for preventing pinching 2 is coupled to the first conduit part 11, and the balloon for expansion to the second conduit part 12 (3) is combined.
그리고, 본 발명은 종래의 벌룬과는 달리, 서로 다른 기능을 발휘하는 끼임방지용 벌룬(2)과 확장용 벌룬(3)을 포함하여 이루어져서, 상기 유두부의 확장은 물론, 결석(C)이 벌룬과 담도벽(E) 사이에 끼이는 것을 억제할 수 있게 한다.In addition, unlike the conventional balloon, the present invention comprises a balloon for preventing pinching (2) and an balloon for expansion (3) that exhibit different functions, and the expansion of the nipple, as well as the absence (C) of the balloon It is possible to suppress the interference between the biliary walls (E).
즉, 상기 끼임방지용 벌룬(2)은, 십이지장에서 담도로 통하는 경로 상에 마련된 유두부를 확장시키는 과정에서 담도 내 결석(C)이 풍선과 담도벽(E) 사이에 결석(C)이 끼이는 것을 억제시키기 위한 것으로, 상기 가이드 도관(1)의 제1도관부(11)를 감싸는 형태로 배치된다. That is, the balloon for preventing pinching (2), in the process of expanding the nipple provided on the path leading to the biliary tract from the duodenum, stones in the biliary tract (C) are interposed between the balloon and the biliary wall (E). To suppress, it is arranged in a form surrounding the first conduit portion 11 of the guide conduit (1).
이러한 끼임방지용 벌룬(2)은, 도 6 내지 도 8에 잘 도시된 바와 같이, 상기 제1도관부(11)를 통해 주입되는 유체에 의해 팽창이 이루어지되, 상기 유두부의 입구 측에서 담도 측으로 갈수록 순차적인 팽창이 이루어짐으로써, 유두부 근처에 위치한 담도 내 결석(C)을 담도벽(E)에 끼이지 않게 밀어낼 수 있게 됨에 따라, 벌룬의 팽창 과정에서 벌룬과 담도벽(E) 사이에 결석(C)이 끼임으로써 초래되는 문제점인 환자의 통증 유발 또는 조직의 손상을 현저히 억제시킬 수 있는 장점을 기대할 수 있게 한다. As shown in FIGS. 6 to 8, the balloon for preventing pinching 2 is expanded by the fluid injected through the first conduit part 11, but gradually increases from the inlet side of the nipple to the biliary side. As phosphorus swelling is performed, stones in the biliary tract located near the nipples can be pushed out of the biliary tract (E) without being trapped, and stones between the balloon and the biliary tract (E) in the course of balloon expansion ( C) It is possible to expect the advantage of significantly inhibiting the patient's pain-causing or tissue damage caused by pinching.
상기 확장용 벌룬(3)은, 상기 끼임방지용 벌룬(2)과는 달리, 원래의 기능인 유두부 확장을 위한 것으로, 상기 가이드 도관(1)의 중심부 및 제2도관부(12)를 감싸는 형태로 배치되고, 도 6 내지 도 8에 잘 도시된 바와 같이, 상기 제1도관부(11)를 통해 주입되는 유체에 의해 팽창이 이루어져서 상기 유두부 입구를 확장시킨다.Unlike the balloon 2 for preventing pinching, the balloon for expansion 3 is intended for expansion of the nipple, which is an original function, and is arranged in a form surrounding the central portion and the second conduit portion 12 of the guide conduit 1 6 to 8, the expansion is made by the fluid injected through the first conduit part 11 to expand the nipple inlet.
이러한 구성을 가지는 본 발명의 일실시예에 따른 내시경적 유두부 확장용 풍선 유닛은, 유두부 확장을 위한 벌룬 구조를 끼임방지용 벌룬(2)과 확장용 벌룬(3)으로 구별하여 형성시키고, 상기 끼임방지용 벌룬(2)이 순차적으로 팽창되도록 구성됨으로써, 유두부 입구 근처에 위치한 결석(C)이 담도벽(E)에 끼이는 것을 억제시킬 수 있게 됨에 따라, 유두부 확장 시술시 환자의 통증이나 조직의 손상을 유발하지 않고 양질의 의료행위 제공을 가능하게 하는 효과를 가진다. The balloon unit for endoscopic papillary expansion according to an embodiment of the present invention having such a configuration is formed by distinguishing the balloon structure for papillary expansion into a balloon for preventing pinching (2) and an balloon for expansion (3), As the balloon for preventing pinching (2) is configured to expand sequentially, it is possible to suppress the stone (C) located near the entrance to the papillary wall into the biliary wall (E), so that the patient's pain or pain during papillary dilation It has the effect of providing quality medical care without causing tissue damage.
한편, 이와 같이 본 발명을 이용하여 내시경적 유두부 확장술이 이루어지고 난 이후에는, 본 발명을 유두부로부터 제거한 후 결석 제거용 포셉 등을 이용하여 결석(C)을 제거하는 시술이 이루어지게 된다. On the other hand, after the endoscopic papillary dilation procedure is performed using the present invention as described above, a procedure for removing the stones (C) using a forceps for removing stones after removing the present invention from the nipple is performed.
본 실시예에 채용된 상기 가이드 도관(1)의 제1도관부(11)는, 팽창을 위한 유체가 상기 끼임방지용 벌룬(2)의 내부공간에 동시에 골고루 유입되지 않고 상기 입구 측에 인접한 부분에만 국부적으로 유입되게 하는 제1유입구(11a)를 포함하여 이루어져서, 도 6 내지 8과 같은 순서로 순차적인 팽창이 원활하게 이루어지게 된다.The first conduit portion 11 of the guide conduit 1 employed in the present embodiment is localized only to a portion adjacent to the inlet side without fluid evenly flowing into the inner space of the balloon 2 for preventing pinching at the same time. It comprises a first inlet (11a) to be introduced into, so that the sequential expansion in the order shown in Figures 6 to 8 is made smoothly.
물론, 이러한 순차적인 팽창이 더욱 원활하게 이루어지게 하기 위해서 상기 끼임방지용 벌룬(2)은, 상기 유두부 측에서 가까운 부분에서 먼 부분 측으로 갈수록 두께가 점점 커지도록 구성되는 것이 바람직하다. 즉, 상대적으로 두께가 얇은 부분부터 공기 압력에 의한 팽창이 이루어지게 하여, 순차적 팽창 동작을 더욱 원활하게 구현할 수 있는 것이다. Of course, in order to make this sequential expansion more smoothly, it is preferable that the balloon for preventing pinching 2 is configured to gradually increase in thickness as it goes closer to the distant portion from the nipple side. That is, the expansion by air pressure is performed from a relatively thin portion, so that a sequential expansion operation can be more smoothly implemented.
이러한 제1도관부(11)와는 대조적으로, 상기 가이드 도관(1)의 제2도관부(12)는, 상기 유체가 상기 확장용 벌룬(3)의 내부공간에 전체적으로 동시에 유입될 수 있도록, 그 내부공간의 길이방향을 따라 간격을 두고 형성된 복수의 제2유입구(12a)들을 포함하여 이루어지고, 모든 부위의 두께가 동일하게 형성되는 것이 바람직하다. In contrast to the first conduit portion 11, the second conduit portion 12 of the guide conduit 1, the internal space so that the fluid can be simultaneously introduced into the entire interior space of the expansion balloon (3) It is made to include a plurality of second inlet (12a) formed at intervals along the longitudinal direction of, it is preferable that the thickness of all parts are formed the same.
상기 끼임방지용 벌룬(2)과 확장용 벌룬(3)은 일체로 형성될 수 있음은 물론이나, 본 실시예에서는 별개로 제작된 후 공기 주입 통로가 서로 소통가능하도록 연결된다. Of course, the balloon 2 for preventing pinching and the balloon 3 for expansion may be integrally formed, but in this embodiment, after separately manufactured, the air injection passages are connected to communicate with each other.
이하에서는 도 9를 참조하여 본 발명의 다른 실시예에 따른 내시경적 유두부 확장용 풍선 유닛을 상세히 설명하기로 한다.Hereinafter, a balloon unit for endoscopic papillary expansion according to another embodiment of the present invention will be described in detail with reference to FIG. 9.

상기 중심측 확장부(51)는 상기 유두부 입구에 삽입되고 두께가 가장 얇은 부분이고, 상기 한 쌍의 순차적 확장부(52)들은 상기 중심측 확장부(51)를 중심으로 서로 대칭으로 형성되되 각각 그 중심측 확장부(51)에서 멀어지는 방향으로 갈수록 점진적으로 두께가 커지는 부분이다.The central side extension portion 51 is inserted into the nipple entrance and is the thinnest portion, and the pair of sequential extension portions 52 are formed symmetrically with respect to the central side extension portion 51. Each is a portion that gradually increases in thickness in the direction away from the central side extension 51.
이러한 구성을 가지는 본 실시예는, 가이드 도관의 공기 유입구에 팽창용 유체가 주입되면, 도 9의 (a)와 같이, 그 공기 유입구에 대응되는 위치에 형성된 중심측 확장부(51)가 팽창됨으로써 유두부를 확장시킬 수 있는 환경을 마련하고, 이후 도 9의 (b) 및 (c)와 같이, 상기 순차적 확장부(52)들이 순차적으로 팽창됨으로써 결석의 끼임방지 및 유두부 확장을 동시에 구현할 수 있는 장점을 기대할 수 있게 한다. In the present embodiment having such a configuration, when the expansion fluid is injected into the air inlet of the guide conduit, as shown in FIG. 9(a), the central side extension 51 formed at the position corresponding to the air inlet is expanded An environment capable of expanding the papilla is provided, and as shown in FIGS. 9(b) and 9(c), the sequential expansions 52 are sequentially expanded to simultaneously prevent the occurrence of stones and the expansion of the nipples. You can expect the advantages.
