Description

담관 내시경 튜브Bile Duct Endoscopic Tube
본 발명은 담관을 관찰할 수 있는 담관 내시경 삽입을 보조하기 위한 튜브에 관한 것이다.The present invention relates to a tube for assisting in the insertion of a bile duct endoscope capable of observing the bile duct.
담도 내시경은 직시하에 담도계질환의 진단 및 치료를 가능하게 하였다. 담관내부를 관찰하기 위해서는 전통적으로 1)경피경간(transhepatic) 담관배액관을 통하여 소구경 내시경을 삽입해서 관찰하는 방법, 2)모내시경(mother scope)과 자내시경(baby scope)을 이용한 모자 방식(mother-baby system)으로 담관 검사를 시행하는 방법, 3)직접 소구경의 내시경을 모자 방식없이 위-십이지장을 통하여 십이지장의 유두팽대부까지 진입을 하여 담관내로 삽입을 하는 방법(direct per-oral cholangioscopy)이 있다. Biliary endoscopy made it possible to diagnose and treat biliary tract diseases under direct vision. Traditionally, to observe the inside of the bile duct, 1) a small-bore endoscope is inserted through a transhepatic bile duct drainage tube, and 2) a mother-and-child method using a mother scope and a baby scope. -baby system) to perform bile duct examination, and 3) direct per-oral cholangioscopy to insert a small-diameter endoscope through the gastro-duodenum to the papillary ampulla of the duodenum without a hat method (direct per-oral cholangioscopy). have.
그러나 경피경간 담관내시경법은 침습성이 높고, 간내담관확장이 있어야 하고, 경피경간담관배액관 삽입후 최소 3-5일 지난 후 시술이 가능하며, 방사선 피폭이 환자와 의료진 모두에게 많이 발생하며 상대적으로 높은 합병증 발생으로 말미암아 시술에 제한이 많다. However, percutaneous transhepatic cholangioendoscopy is highly invasive, requires intrahepatic bile duct dilatation, can be performed at least 3-5 days after insertion of a percutaneous transhepatic cholangioduct, and causes a lot of radiation exposure to both patients and medical staff, and is relatively high. There are many limitations to the procedure due to the occurrence of complications.
모자 방식의 경구 담도 내시경은 모내시경을 십이지장으로 삽입후 유두팽대부에 대하여 내시경 유두 괄약근 절개술(endoscopic sphincterotomy, EST) 시행 후에 이곳으로 직시형인 자내시경을 측시형인 모내시경의 겸자공을 통해 담도 내로 삽입하여 병변의 관찰 및 치료를 시도하는 방법이다. 최근 Spyglass system (Boston Scientific, USA)은 획기적인 1 회용 자내시경을 사용한 담관내시경방법으로 담관내부를 실시간 직접 관찰 및 직시하 조직검사를 가능하게 하여 담관내시경분야의 진단방법에 많은 발전을 이루었다. 또 다른 방법인 소구경내시경을 이용한 직접 담관내시경 삽입법은 위-십이지장 굴곡부를 통과하여 담관내로 내시경을 삽입하는 방법으로 고난이도의 삽입기술이 필요하여 배우기 어렵고, 내시경의 손상이 심하여 저변확대가 어려워 일반적으로 활용하기에는 무리가 많다.The mother-and-child method of oral biliary endoscopy is performed by inserting the mother endoscope into the duodenum, performing endoscopic sphincterotomy (EST) on the papillary ampulla, and then inserting the direct-view endoscope into the biliary tract through the forceps hole of the side-view mother endoscope. It is a method of trying to observe and treat lesions. Recently, the Spyglass system (Boston Scientific, USA) is a cholangioscopic method using an innovative single-use endoscope, which enables real-time direct observation of the inside of the bile duct and biopsy under direct view, and has made great progress in diagnostic methods in the field of cholangioscopic endoscopy. Another method, the direct insertion of a cholangioscopic endoscope using a small bore endoscope, is a method of inserting an endoscope into the bile duct through the gastroduodenal bend. It's too much trouble to use.
그러나 상기와 같은 종래 기술의 경우, 시술의 높은 침습성과 합병증, 제한사항 등으로 보편적으로 시행하기 어렵고, 1회용 내시경인 Spyglass system (Boston Scientific, USA)은 많은 문제점을 해결하였으나 여전히 조작이 어려우며, 담관 내부를 촬영한 영상의 화질이 일반내시경처럼 선명하지 않고, 비용면에서 경제적이지 못하다는 문제가 있다. 소구경내시경을 이용한 직접 담관내시경 삽입법은 화질면에서는 우수하나 배우기 어렵고, 내시경의 손상이 심하여 일반적으로 활용하기에는 무리가 많다.However, in the case of the prior art as described above, it is difficult to perform universally due to the high invasiveness of the procedure, complications, and limitations, and the disposable endoscope Spyglass system (Boston Scientific, USA) has solved many problems, but is still difficult to manipulate, and the bile duct There is a problem that the image quality of the image taken inside is not as clear as that of a general endoscope and is not economical in terms of cost. The direct cholangioscopic insertion method using a small bore endoscope is excellent in terms of image quality, but difficult to learn, and it is difficult to use in general due to severe damage to the endoscope.
이에, 본 발명은 제조 비용이 저렴하고, 제조가 간편하여 일회용으로 사용하기에 적합하고, 기존의 개발된 소구경 내시경 기기를 이용할 수 있으며, 담관 내부를 선명한 화질로 촬영할 수 있도록 기존의 소구경 내시경을 십이지장까지 삽입하여 담관내로 삽입을 보조하는 담관 내시경 튜브를 제공하는데 목적이 있다.Therefore, the present invention is suitable for disposable use due to its low manufacturing cost and simple manufacturing, can use an existing small-bore endoscope device, and uses an existing small-bore endoscope to capture the inside of the bile duct with clear image quality. An object of the present invention is to provide a bile duct endoscope tube that assists insertion into the bile duct by inserting it into the duodenum.

다양한 실시예에 따르면, 마개(500)에는 튜브본체(100) 외부와 내부를 연통하는 가이드 홀(510)이 형성되어 내시경 기기가 가이드 홀(510)을 통해 유입되도록 가이드할 수 있다.According to various embodiments, a guide hole 510 communicating the outside and inside of the tube body 100 is formed in the stopper 500 so that an endoscope device can be introduced through the guide hole 510 .
다양한 실시예에 따르면, 튜브본체(100)의 외측면에는 길이 방향을 따라 눈금이 형성될 수 있고, 눈금을 통해 튜브가 인체 내부에 삽입된 삽입된 길이를 확인할 수 있다.According to various embodiments, graduations may be formed on the outer surface of the tube body 100 along the longitudinal direction, and the inserted length of the tube inserted into the human body may be confirmed through the graduations.
튜브본체(100)에는 미리 정해진 간격마다 방사선 마커를 부착할 수 있다. 방사선 마커는 빛을 투과될 수 있어 환자 내부 장기에 배치된 튜브의 각각의 굴곡부가 적절한 위치에 배치되어 있는지 확인할 수 있도록 한다.A radiation marker may be attached to the tube body 100 at predetermined intervals. Since the radiation marker can transmit light, it can be checked whether each bent part of the tube disposed in the patient's internal organs is disposed in an appropriate position.
이상 실시예를 통해 본 기술을 설명하였으나, 본 기술은 이에 제한되는 것은 아니다. 상기 실시예는 본 기술의 취지 및 범위를 벗어나지 않고 수정되거나 변경될 수 있으며, 본 기술분야의 통상의 기술자는 이러한 수정과 변경도 본 기술에 속하는 것임을 알 수 있을 것이다.Although the present technology has been described through the above embodiments, the present technology is not limited thereto.
