According to the present invention, in a process of expanding papilla, it is possible to prevent a stone from being caught between a balloon and a biliary tract wall.

Description

내시경적 유두부 확장용 풍선 유닛{Endoscopic duodenum papillar balloon unit}Endoscopic duodenum papillar balloon unit

본 발명은 내시경적 유두부 확장용 풍선 유닛에 관한 것으로, 더욱 상세하게는 십이지장에서 담도로 통하는 경로 상에 마련된 유두부를 확장시키는 과정에서 담도 내에 존재하는 결석이 확장되는 풍선에 의해 담도벽에 압력을 가함으로써 환자의 통증 또는 조직의 손상 등을 유발시키는 것을 억제시킬 수 있도록, 구조가 개선된 내시경적 유두부 확장용 풍선 유닛에 관한 것이다. The present invention relates to a balloon unit for endoscopic papillary expansion, and more specifically, pressure in the bile duct wall by a balloon in which stones present in the biliary tract expand in the process of expanding the papillae provided on the path leading from the duodenum to the biliary tract. The present invention relates to a balloon unit for endoscopic papillary expansion with an improved structure, so as to inhibit the patient from causing pain or tissue damage.

담도(A)는 인체의 간에서 분비된 쓸개즙(담즙)이 십이지장으로 배출되는 경로를 의미하는데, 도 1에 잘 도시된 바와 같이, 이러한 담도(A)에는 결석(C)이 발생하여 통증이나 조직의 손상을 유발하게 된다. The biliary tract (A) refers to a path through which the gallbladder juice (biliary) secreted from the liver of the human body is discharged into the duodenum. As is well illustrated in FIG. 1, such biliary tract (A) has stones (C) that cause pain or tissue. Cause damage.

따라서, 담도(A)에 존재하는 결석(C)을 제거하기 위한 시술이 요구되는데, 이러한 시술을 원활하게 하기 위해서는 도 2에 잘 도시된 바와 같이, 내시경과 풍선(B)을 이용한 유두부 풍선 확장술(EPBD)과 같은 방법에 의해 십이지장에서 담도로 통하는 경로 상에 마련된 유두부(D)를 확장시킨 이후 넓어진 유두부(D)를 통해 결석(C)을 바스켓 등을 이용하여 제거하여 왔다. Therefore, a procedure for removing the stones (C) existing in the biliary tract (A) is required. To facilitate this procedure, as shown in FIG. 2, the expansion of the papillary balloon using the endoscope and the balloon (B) After extending the nipple (D) provided on the path leading from the duodenum to the biliary tract by the same method as (EPBD), stones (C) have been removed using a basket or the like through the widened nipple (D).

그러나, 담도 내에 존재하는 결속 제거를 위해 시행되는 종래기술에 의한 내시경적 유두부 풍선 확장술에 의하면, 도 3에 잘 도시된 바와 같이, 풍선(B)이 확장되는 과정에서 담도벽(E)에 결석(C)이 끼어 담도벽(E)에 압력을 가함으로써, 시술 중 환자의 통증을 유발할 뿐만 아니라, 담도벽(E)의 손상, 심지어는 천공까지 유발하게 되는 문제점이 있었다.  However, according to the endoscopic papillary balloon dilatation technique according to the prior art, which is performed to remove the cohesion existing in the biliary tract, as shown in FIG. 3, the balloon (B) is absent in the biliary tract (E) in the course of expansion. There was a problem in that (C) was inserted to apply pressure to the biliary wall (E), causing not only patient pain during the procedure, but also damage to the biliary wall (E) and even perforation.

이들 도면에 도시된 바와 같이, 본 발명의 일실시예에 따른 내시경적 유두부 확장용 풍선 유닛은, 십이지장에서 담도로 통하는 경로 상에 마련된 유두부를 확장시키기 위한 것으로, 가이드 도관(1)과 끼임억제유닛(2)을 포함하여 이루어진다.As shown in these drawings, the balloon unit for endoscopic papillary expansion according to an embodiment of the present invention is for expanding a papillary portion provided on a path leading to the biliary tract from the duodenum, and guide conduit (1) and pinching inhibition It comprises a unit (2).

상기 가이드 도관(1)은, 도 4 및 도 5에 잘 도시된 바와 같이, 상기 십이지장에서 담도까지 길게 삽입되어 있는 가이드 와이어(G)를 감싸는 형태로 그 가이드 와이어(G)에 상대이동 가능하게 설치됨으로써, 상기 끼임억제유닛(2)과 함께 가이드 와이어(G)를 따라 이동하여 상기 유두부 측에 원활하게 접근될 수 있게 된다.The guide conduit (1), as well shown in Figures 4 and 5, in the form surrounding the guide wire (G) that is inserted long from the duodenum to the biliary duct is installed to be movable relative to the guide wire (G) By this, it is possible to smoothly access the nipple side by moving along the guide wire G together with the pinch restraining unit 2.

본 발명에 의하면, 도 7의 (a)에 도시된 종래의 벌룬 구조와는 달리, 도 7의 (b)와 같이 상기 끼임억제유닛(2)의 벌룬부(21)의 팽창 과정에서 결석(C)이 담도벽에 끼이지 않을 수 있는 공간, 즉 끼임방지홈(24)을 최대한 확보활 수 있도록 구성됨으로써, 상기 유두부의 확장은 물론, 결석(C)이 풍선과 담도벽 사이에 끼이는 것을 억제할 수 있게 한다. According to the present invention, unlike the conventional balloon structure shown in Figure 7 (a), as shown in Figure 7 (b), absent in the expansion process of the balloon portion 21 of the pinch suppression unit (C) (C ) Is configured to secure the space that can not be caught in the bile duct wall, that is, the pinch prevention groove 24 as much as possible, so that the expansion of the nipple, as well as the absence (C) is suppressed from being caught between the balloon and the biliary wall Make it possible.

즉, 상기 끼임억제유닛(2)은, 십이지장에서 담도로 통하는 경로 상에 마련된 유두부를 확장시키는 과정에서 도 5와 같이 플랫한 상태에서 도 6과 같이 팽창되는데, 이러한 동작 과정 중에 담도 내 결석(C)이 풍선과 담도벽 사이에 끼이는 것을 억제시키기 위한 것으로, 벌룬부(21)와 슬라이딩부(22)와 여결부를 포함하여 이루어진다.That is, the pinch inhibiting unit 2 expands as shown in FIG. 6 in a flat state as shown in FIG. 5 in the process of expanding the nipple provided on the path leading from the duodenum to the biliary tract. ) Is to prevent the sandwich between the balloon and the biliary wall, it comprises a balloon portion 21 and the sliding portion 22 and the filter portion.

상기 벌룬부(21)는, 상기 가이드 도관(1)을 감싸는 형태로 배치되고, 상기 슬라이딩부(22)는, 마치 우산의 중심대에 우산살이 연결된 허브체가 이동가능하게 설치된 것과 유사하게, 상기 가이드 도관(1)에 상대이동 가능하게 설치된다.The balloon portion 21 is disposed in a form surrounding the guide conduit 1, and the sliding portion 22 is similar to that of a guide in which a hub body connected to an umbrella body is movably installed at the center of an umbrella. Relatively movable in the conduit (1).

그리고, 상기 연결부(23)는 도 4 및 도 6에 잘 도시된 바와 같이, 일측이 상기 슬라이딩부(22)에 연결되고 타측이 상기 벌룬부(21)의 양단 중 어느 하나에 연결된다.In addition, the connection portion 23, as well shown in Figures 4 and 6, one side is connected to the sliding portion 22 and the other side is connected to any one of both ends of the balloon portion (21).

이러한 구성을 가지는 본 발명의 일실시예에 따른 내시경적 유두부 확장용 풍선 유닛은, 끼임억제유닛(2)의 벌룬부(21)의 팽창과 함께 연결부(23)와 슬라이딩부(22)가 동작하면서 도 7의 (b)와 같이 그 사이에 결석(C)이 수용될 수 있는 끼임방지홈(24)을 형성시킬 수 있도록 구성됨으로써, 벌룬의 팽창 과정에서 벌룬과 담도벽 사이에 결석(C)이 끼임으로써 초래되는 문제점인 환자의 통증 유발 또는 조직의 손상을 현저히 억제시킬 수 있는 장점을 기대할 수 있게 한다. In the balloon unit for endoscopic papillary expansion according to an embodiment of the present invention having such a configuration, the connection portion 23 and the sliding portion 22 are operated together with the expansion of the balloon portion 21 of the pinch restraining unit 2 While being configured to be able to form a pinch prevention groove 24 that can be accommodated between the stones (C) as shown in Figure 7 (b), during the balloon expansion process, the stones between the balloon and the biliary wall (C) It is possible to expect the advantage of significantly inhibiting the patient's pain-causing or tissue damage, which is a problem caused by this pinching.

본 실시예에 채용된 연결부(23)는, 상기 슬라이딩부(22)와 벌룬부(21)를 서로 연결시키고 상기 벌룬부(21)의 팽창시에 슬라이딩부(22)와의 사이에 끼임방지홈(24)을 형성할 수 있는 어떠한 구조로 구현될 수 있임은 물론이나, 상기 벌룬부(21)의 팽창시에 상기 슬라이딩부(22)와 연결부(23) 사이에 끼임방지홈(24)이 원활하게 형성될 수 있도록, 상기 슬라이딩부(22)와 상기 벌룬부(21)의 어느 하나의 가장자리와의 사이에 방사형으로 배열되는 복수의 우산살 형태의 살대들을 포함하여 이루어지는 것이 바람직하다. The connecting portion 23 employed in this embodiment connects the sliding portion 22 and the balloon portion 21 to each other and prevents a pinching groove between the sliding portion 22 when the balloon portion 21 is inflated ( 24) can be implemented in any structure capable of forming, as well as, when the balloon portion 21 is expanded, the pinch prevention groove 24 between the sliding portion 22 and the connecting portion 23 is smoothly In order to be formed, it is preferable that the sliding portion 22 and a plurality of umbrella-shaped ribs are arranged radially between any one edge of the balloon portion 21.

그리고, 상기 각 살대는, 일측이 상기 슬라이딩부(22)에 연결되고 타측이 상기 벌룬부(21)의 가장자리에 연결되되, 상기 슬라이딩부(22)에 연결된 일측이 상기 벌룬부(21)에 연결된 타측에 비해 상기 유두부 측에 가깝게 배치됨으로써, 도 5에서 도 6과 같이 벌룬부(21)가 팽창되는 경우에, 상기 벌룬부(21)에 의해 원뿔 형태의 공간이 형성되게 하여 결석(C)이 도 7의 (a)와 같이 담도벽에 끼이지 않고 도 7의 (b)와 같이 상기 원뿔 형태의 공간인 끼임방지홈(24)에 원활하게 수용될 수 있게 한다. And, each of the flesh, one side is connected to the sliding portion 22 and the other side is connected to the edge of the balloon portion 21, one side connected to the sliding portion 22 is connected to the balloon portion 21 By being disposed closer to the nipple side than the other side, when the balloon portion 21 is expanded as shown in FIG. 5 to FIG. 6, the balloon portion 21 forms a cone-shaped space to form stones (C). As shown in Fig. 7 (a), it is not caught in the wall of the biliary tract, and as shown in Fig. 7 (b), it can be smoothly accommodated in the pinch prevention groove 24, which is a conical space.

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.
