Description

뇌척수액 운송용 도관의 이탈 방지 장치Cerebrospinal fluid transport conduit

본 발명은 뇌척수액 운송용 도관의 이탈 방지 장치에 관한 것으로, 더욱 상세하게는 뇌척수액 단락술 중 하나인 뇌실-복강 단락술시 사용되는 도관을 복강에 견고히 고정시킬 수 있도록 하고, 과도한 고정에 의해 도관이 막히는 것을 방지시킬 수 있도록, 구조가 개선된 뇌척수액 운송용 도관의 이탈 방지 장치에 관한 것이다. The present invention relates to a device for preventing the escape of the cerebrospinal fluid transport conduit, and more particularly, it is possible to firmly fix the conduit used in ventricular-abdominal shunting, which is one of the cerebrospinal fluid shunts, to the abdominal cavity, and to prevent the conduit from being blocked by excessive fixation. The present invention relates to an apparatus for preventing departure of a cerebrospinal fluid transport conduit having an improved structure.

수두증이란 뇌척수액의 유출로가 차단되거나 뇌척수액의 생성과 흡수의 불균형이 발생함으로 인해 과다하게 축적된 뇌척수액이 뇌실을 확장시키거나 두개강 내부의 압력을 증가시킨 상태를 말하며, 소아에서 선천적 기형으로 인해 수두증이 발생하거나, 뇌출혈이나 감염, 뇌종양 등의 후천적 이유로 발생하기도 한다. Hydrocephalus refers to a condition in which excessively accumulated cerebrospinal fluid expands the ventricles or increases pressure in the cranial cavity due to blocked outflow of cerebrospinal fluid or an imbalance in the production and absorption of cerebrospinal fluid.In children, hydrocephalus is caused by congenital malformations. It may also occur for acquired reasons, such as cerebral hemorrhage, infection, or brain tumor.

특히, 중증 두부 외상의 72~86%에서 뇌실의 확장을 볼 수 있으며, 치료는 거의 대부분 뇌척수액 단락술에 의존하며, 가장 흔히 시행하는 방법이 뇌실-복강 단락술이다.In particular, ventricular dilatation is seen in 72-86% of severe head trauma. Treatment is mostly dependent on cerebrospinal fluid shunting, and the most common practice is ventricular-abdominal shunting.

뇌실-복강 단락술이란, 도 1과 같이 뇌실(A)과 복강(B)을 도관(100)을 통하여 연결시켜 뇌실(A)에 있는 과도한 뇌척수액을 복강(B)으로 보내는 수술이다. Ventricular-abdominal shunting is surgery to connect the ventricle (A) and the abdominal cavity (B) through the conduit 100 as shown in Figure 1 to send excess cerebrospinal fluid in the ventricles (A) to the abdominal cavity (B).

뇌실-복강 단락술의 가장 흔한 합병증은 단락 부전과 감염으로 각각 17.8%, 6.4%까지 보고되고 있으며, 단락 부전 중 도관의 전위(displacement)가 약 8.8%, 도관의 폐쇄가 23.5% 정도로 보고되고 있다.The most common complications of ventricular-abdominal shunting have been reported to be 17.8% and 6.4%, respectively, with short-circuit insufficiency of about 8.8% and closure of catheter 23.5%.

In general, in order to perform ventricular-peritoneal shunting, as shown in FIG. 2, the catheter 100 must be connected in the abdominal cavity B through a hole formed in the peritoneum C. In order to secure the fixation force in (B), the bag is sutured around the peritoneum (C) where the hole is formed, but when the ligation is loose after suture, the fixation force to the conduit (100) of the peritoneum (C) is weak. Dislocations may occur and blockage of the conduit 100 may occur if the ligation is excessive.

The present embodiment having such a configuration allows the conduit 50 to easily enter the fixing part 30 side through the slits 12 and 22, thereby preventing the departure of the conduit for cerebrospinal fluid transport according to the present embodiment. And the binding process between the conduit 50 can be performed smoothly.

그리고, 본 실시예는, 도 4에 잘 도시된 바와 같이, 상기 도관(50)이 상기 슬릿(12)(22)을 경유하여 관통공에 위치하는 경우에, 그 슬릿(12)(22)의 간격을 좁혀 줌으로써 상기 도관(50)과 고정부(30) 간의 결합력을 더욱 크게 확보할 수 있게 하는 결속용 와이어(40)를 포함하여 이루어진다.In this embodiment, as shown in FIG. 4, when the conduit 50 is positioned in the through hole via the slits 12 and 22, the slits 12 and 22 of the slits 12 and 22 are formed. It comprises a binding wire 40 to narrow the gap to ensure a greater coupling force between the conduit 50 and the fixing portion 30.

이러한 구성을 가지는 본 실시예는, 상기 결속용 와이어(40)를 이용하여 상기 고정부(30)에 힘을 가하게 되면, 상기 슬릿(12)(22)을 한정하는 슬릿면들이 서로 접촉될 때까지 그 고정부(30)의 내경이 축소되게 된다. In this embodiment having such a configuration, when a force is applied to the fixing part 30 using the binding wire 40, the slit surfaces defining the slits 12 and 22 are in contact with each other. The inner diameter of the fixing portion 30 is reduced.

이와 같이 되면, 도관(50)이 상기 고정부(30)에 의한 가압으로 견고히 고정됨은 물론, 상기 슬릿면들 간의 접촉에 의해 고정부(30)의 도관(50)에 대한 과도한 가압이 방지됨으로써 도관(50)의 막힘이나 폐쇄 현상이 발생되지 않게 된다. In this case, as well as the conduit 50 is firmly fixed by the pressure by the fixing portion 30, as well as the excessive pressure on the conduit 50 of the fixing portion 30 by the contact between the slit surfaces to prevent the conduit Blocking or closing phenomenon of (50) does not occur.

본 실시예에서, 상기 고정부(30)는 상기 도관(50)의 외면에 걸리는 복수의 걸림돌기(32)들을 포함하고, 상기 도관(50)은 상기 고정부(30)의 걸림돌기(32)들에 결합되는 걸림부(52)를 포함하여 이루어져서, 도 4의 (b) 및 도 5와 같이 고정부(30)의 내면과 도관(50)의 외면이 접촉되어 있는 경우에 고정부(30)와 도관(50) 간의 고정력을 더욱 크게 확보할 수 있게 한다. In this embodiment, the fixing part 30 includes a plurality of locking protrusions 32 caught on the outer surface of the conduit 50, and the conduit 50 includes the locking protrusion 32 of the fixing part 30. Including the engaging portion 52 coupled to the two, as shown in Figure 4 (b) and 5, the fixing portion 30 when the inner surface of the fixing portion 30 and the outer surface of the conduit 50 is in contact with And to secure a greater holding force between the conduit 50.
