Abstract

The invention discloses a nasal and bile external drainage tube for preventing papillary bleeding and an application thereof. The nasal and bile external drainage tube for preventing nipple bleeding comprises a first straight tube, a first drainage tube segment, and a second drainage tube in which lumens are sequentially connected. Pipe section, the third drainage pipe section, the fourth drainage pipe section and the second straight pipe; the first straight pipe includes the head end, the first pipe section and the second pipe section which are communicated in turn with the lumen; the first pipe section includes a plurality of axes with the first pipe section It is an arc-shaped pipe wall whose axes are evenly distributed and protrudes away from the axis of the first pipe section. The two ends of the arc-shaped pipe wall are respectively connected with the lower end of the head end and the upper end of the second pipe section; The drainage tube section is a straight tube, and a balloon is sheathed on its outer wall. The nasal and bile external drainage tube for preventing nipple bleeding of the present invention is provided with a balloon, which can compress the incised nipple and prevent delayed bleeding; the first drainage tube section is a spiral elastic tube, through its own elastic tension and thread tension Keeping the balloon compressing the nipple.

Description

technical field [0001] The invention relates to a nasobiliary drainage tube and its application, in particular to a nasobiliary external drainage tube for preventing nipple bleeding and its application. Background technique [0002] With the continuous development of endoscopic technology and the continuous improvement of its accessories, duodenoscopy (ERCP) has become an important measure for the treatment of hepatobiliary and pancreatic diseases, including common bile duct stones, bile duct injury, bile duct stricture, and postoperative liver transplantation. Biliary complications, etc. Compared with traditional laparotomy, this technique has the advantages of less trauma, higher safety factor, and faster recovery. Under direct vision, hepatobiliary and pancreatic diseases that cannot be detected by conventional hepatobiliary, spleen, and pancreatic CT, ultrasound, and magnetic resonance examinations can be detected and treated at the same time, such as duodenal papilliti...
