Problems solved by technology

[0005] The head of the nasobiliary drainage tube currently used clinically can entangle itself in the bile duct, but the stimulation of the head of the drainage tube to the bile duct mucosa can lead to local mucosal reactive hyperplasia; during the extubation process, the head of the drainage tube can cause bile duct and Injury to the intestinal mucosa can even induce complications such as acute cholangitis, acute pancreatitis, and upper gastrointestinal bleeding; irritation of the throat by the drainage tube often leads to severe nausea and even vomiting in patients

Embodiment 1

[0045] Such as Figure 1-Figure 9 As shown, an integrated bile and pancreatic juice drainage tube includes a water bladder type bile external drainage tube 1 and a pancreatic juice internal drainage tube 2,

[0046] The water bladder type bile external drainage tube 1 includes a drainage tube section I11, a drainage tube section II12 and a drainage tube section III13 connected in sequence, the outer wall of the drainage tube section II12 is sleeved with a balloon membrane 14, and the cross section of the balloon membrane 14 is In the shape of a quincunx, the drainage tube section I11 is provided with a pipeline I111 communicating with the drainage tube section II12 and a pipeline II112 communicating with the balloon membrane 14, the other end of the pipeline II112 is connected to the tube 4 through the cap 3, The other end of the pipe 4 is connected to a three-way valve, the cap 3 has a cylindrical head 31 and a truncated conical tail 32, the small end of the truncated conical...

Embodiment 2

[0064] An integrated bile-pancreatic juice drainage tube, such as Figure 10 As shown, it differs from Example 1 in that its line 5' has a turn-back portion 51', and the line 5' is connected to the tail of the drainage tube 23 through the turn-back portion 51', and the line 5' The two ends of the two ends pass through the side wall of the drainage tube section III13 and enter the lumen of the drainage tube section III13, that is, the wire 5' is folded in half at the turning part 51' to form a double-strand wire, and the double-strand wire The end of the wire away from the turning part 51 ′ is located in the lumen of the drainage tube section III13.

[0065] In addition to taking out the water bladder type bile external drainage tube 1 and the pancreatic juice internal drainage tube 2 at the same time as described in Example 1, the removal method of an integrated bile-pancreatic juice drainage tube in this embodiment also includes taking out only the water In the case of cysti...

Abstract

The invention discloses an integrated bile and pancreatic juice drainage pipe which comprises a water sac type bile outer drainage pipe and a pancreatic juice inner drainage pipe. The water sac type bile outer drainage pipe comprises a drainage pipe section I, a drainage pipe section II and a drainage pipe section III which are communicated in sequence. The outer wall of the drainage pipe section II is sleeved with a balloon thin film. The pancreatic juice inner drainage pipe comprises a drainage pipe body, a pipe cap and a drainage pipe tail portion. The end, far away from the drainage pipe section II, of the drainage pipe section III is matched with the drainage pipe tail portion. The integrated bile and pancreatic juice drainage pipe has strong tension force, can have the function of avoiding disengagement of the water sac type bile outer drainage pipe, is suitable for bile ducts of various diameters, has no damage to bile duct mucosa, duodenal papillae and upper gastrointestinal tract mucosa, and cannot cause obstruction of biliary tracts while avoiding displacement of the water sac type bile outer drainage pipe. The pancreatic juice inner drainage pipe is connected with the water sac type bile outer drainage pipe through a line, and the function of avoiding displacement or disengagement of the pancreatic juice inner drainage pipe is achieved.

Description

technical field [0001] The invention relates to a drainage tube, in particular to an integrated bile and pancreatic juice drainage tube. Background technique [0002] At present, 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 choledocholithiasis, bile duct injury, bile duct stricture, and liver transplantation. Posterior 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, duodenal ...
