Bile-pancreatic drainage tube with stone balloon

Abstract

The invention discloses a bile-pancreatic drainage tube with a stone balloon, comprising an internal and external biliary drainage tube with the stone balloon and an internal pancreatic drainage tube,which is characterized in that the bile-pancreatic drainage tube with a stone balloon comprises a tube cap connected sequentially with the lumen, a drainage tube section I, a drainage tube section II, a drainage tube section III, a drainage tube section IV, a drainage tube section V, a drainage tube section VI, a drainage tube section VII and a drainage tube section VIII. The drainage pipe section II is linear, and the outer wall of the drainage pipe section II is connected with a balloon film I in sleeve; and the drainage pipe section V is linear, and the outer wall of the drainage pipe section V is connected with a balloon film II in sleeve. The balloon film I and the balloon film II on the drainage pipe section II and drainage pipe section V of the bile-pancreatic drainage tube with the stone balloon have the advantage of anti-slippage. The size of the balloon film I and the balloon film II is variable (0.5-2.0 cm), which is suitable for bile ducts of various diameters. When residual stones are found in the common bile duct by cholangiography, a filling balloon film I can drag the residual stones into the duodenum.

Description

technical field [0001] The invention relates to a drainage tube device, in particular to a bile and pancreatic juice drainage tube with a stone extraction balloon. 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, papillary stenosis, parapapillary diverticulum, ...

AI Technical Summary

Problems solved by technology

The drainage tube has the following disadvantages: 1. The head end of the drainage tube is naturally looped, and its fixing force is small, and the drainage tube is prone to prolapse; 2. It only has the effect of bile external drainage, and the continuous loss of bile will cause bile to neutralize gastric acid, The functions of killing bacteria, digesting fat, and stimulating intestinal peristalsis are weakened, and complications such as metabolic acidosis and malnutrition occur; 3. Placement of nasobiliary drainage tubes leads to pyloric sphincter dysfunction and gastric mucosal damage, and bile reflux gastritis is prone to occur , gastric ulcer and other complications; 4. During angiography through the nasobiliary drainage tube, the drainage tube body is blocked in the duodenal papilla, which affects the contrast medium excretion into the duodenum, causing the contrast medium to flow back into the intrahepatic bile duct, causing Biliary blood reflux leads to acute cholangitis, and at the same time, the imaging effect of the middle and lower part of the common bile duct is poor; 5. During extubation, the head of the loop drainage tube can cause damage to the bile duct and intestinal mucosa, and even induce Complications such as acute cholangitis, acute pancreatitis, and upper gastrointestinal bleeding; 6. There are residual stones in the common bile duct, and a second ERCP stone removal operation is required. At this time, after the drainage tube is removed, obstruction caused by stones blocking the common bile duct occurs again Complications such as acute jaundice, acute cholangitis, and acute pancreatitis
