Common bile duct exploring sheath duct

Abstract

The invention discloses a common bile duct exploring sheath tube, which is characterized in that: the sheath tube comprises a horizontal tube located at the head of the sheath tube and a vertical tube. The horizontal pipe and the vertical pipe are communicated with each other through an elbow pipe. An end of the horizontal pipe remote from the elbow pipe is provided with an opening. The outer edgeof the elbow pipe is provided with a through hole along the pipe wall. The outer wall of the vertical pipe is provided with a water outlet joint. A base is arranged one end of the vertical pipe far away from the elbow pipe. The base is provided with a channel communicating with the vertical pipe. An anti-reflux pad is arranged on the inner wall of the channel. The anti-reflux cushion is providedwith an elastic hole for the choledochoscope to pass through. After the invention enters the common bile duct, the pneumoperitoneum and the laparoscopic video can be closed, thereby avoiding the complications caused by the long-term pneumoperitoneum and the loss of the laparoscopic system. A suction tube is connecte with that water outlet connector, so that infectious bile, irrigation fluid, sediment-like calculus and biliary mud can be expel from the body, and the complications caused by the above substances entering the abdominal cavity can be reduced.

Description

technical field [0001] The invention relates to a common bile duct exploration sheath, in particular to a common bile duct exploration sheath for choledochoscopy. 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.

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 wall at the head end is easy to damage the choledochoscope
