Abstract

The invention discloses a nasobiliary external drainage tube for preventing nipple bleeding and application thereof. The nasobiliary external drainage tube for preventing nipple hemorrhage comprises afirst straight tube, a first drainage tube section, a second drainage tube section, a third drainage tube section, a fourth drainage tube section and a second straight tube whose lumens are communicated in turn. The first straight pipe comprises a head end, a first pipe section and a second pipe section, wherein the head end is communicated with the lumen in turn; the first tube section includesa plurality of arcuate tube walls uniformly distributed about the axis of the first tube section and protruding away from the axis of the first tube section, the two ends of the arcuate tube walls being connected with the lower end of the head end and the upper end of the second tube section, respectively. The first drainage tube section is a helical elastic tube; the second drainage tube sectionis a straight tube, and the outer wall thereof is sleeved with a balloon. The nasobiliary external drainage tube for preventing nipple hemorrhage is provided with a balloon, which can produce compression effect on the cut nipple and prevent delayed hemorrhage; the first drainage tube segment is a spiral elastic tube, and the balloon is kept to compress the nipple by its elastic tension and the tension of the thread.

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 papillary 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, liver transplantation, etc. Biliary complications, etc. Compared with traditional laparotomy, this technique has the advantages of less trauma, high safety factor, and faster recovery. Under direct vision, it can detect hepatobiliary and pancreatic diseases that cannot be detected by conventional liver, gallbladder, spleen and pancreas CT, ultrasound and magnetic resonance examinations, and treat them at the same time, such as duodenal papillitis, papill...
