Common bile duct probing sheathing tube with annular balloons

Abstract

The invention discloses a common bile duct probing sheathing tube with annular balloons. A drainage tube segment I, a drainage tube segment II, a drainage tube segment III, a drainage tube segment IVand a drainage tube segment V which are connected with one another are sequentially arranged from the head to the tail of the sheathing tube; a channel I is formed in the drainage tube segment I, theend, at the head of the sheathing tube, of the channel I is closed, and two opposite side holes which are communicated with the channel I are formed in the outer wall of the drainage tube segment I; the side holes are located in the outer side of the drainage tube segment I and correspondingly provided with shrunken balloon containing grooves, and the annular balloons corresponding to the side holes are arranged in the shrunken balloon containing grooves; a channel II communicated with the channel I is formed in the drainage tube segment II, and the outer wall of the drainage tube segment II is sleeved with a balloon. The two annular balloons are made to be full, and then separately enter the upper segment and the lower segment of the common bile duct, so that the sheathing tube is prevented from moving; the two annular balloons and the balloon are made to be full and then close the incision of the common bile duct, and therefore it can be avoided that infectious bile, flushing fluid,muddy stones, biliary sludge and others enter the abdominal cavity.

Description

technical field [0001] The invention relates to a common bile duct exploration sheath, in particular to a common bile duct exploration sheath with an annular balloon. Background technique [0002] Extrahepatic and extrahepatic bile duct stones are common and frequently-occurring diseases in my country. Common bile duct stone removal is the main surgical method for the treatment of this disease. The traditional surgical method is open common bile duct exploration, which has the disadvantages of large trauma and slow recovery. With the development of laparoscopy and choledochoscopy technology, the treatment of intrahepatic and extrahepatic bile duct stones is mostly carried out by laparoscopic common bile duct exploration and choledochoscopy stone removal. Compared with traditional open surgery, it has the advantages of less trauma, faster recovery, and less complications. Advantages such as less symptoms. [0003] At present, there are many disadvantages when inserting a cho...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many disadvantages when inserting a choledochoscope from the cannula of the abdominal puncture device for common bile duct exploration and stone removal: 1. Pneumoperitoneum needs to be established during the entire operation, and long-term pneumoperitoneum is likely to affect the diaphragm muscle Swing, affecting breathing and circulation, absorption of a large amount of carbon dioxide can lead to acidosis and ion disorder, high-pressure carbon dioxide reflux through the vein, and even gas embolism, endangering the life of the patient; , biliary sludge and choledochoscope flushing fluid flow into the abdominal cavity through the incision, which can easily lead to abdominal infection and abdominal abscess, while gravel and biliary sludge enter the abdominal cavity and are difficult to remove, resulting in abdominal adhesions, intestinal obstruction, internal fistula, abdominal abscess and other complications 3. After the common bile duct is incised, the pressure of the common bile duct decreases and collapses, which increases the difficulty of entering the common bile duct with the choledochoscope; 4. The poking card outer tube is made of hard plastic, and the tube wall at the head end is easy to damage the choledochoscope; 5. Repeated entry and exit of the choledochoscope into the common bile duct may easily lead to incision bleeding
