Description
Technical field
The utility model relates to a kind of exploration of common bile duct sheath, the exploration of common bile duct sheath of specifically a kind of choledochoscope
Pipe.
Background technique
Liver inside and outside bile duct stone is the common disease and frequently-occurring disease in China, and it is treat the disease main that exploration of common bile duct, which takes stone,
Modus operandi, traditional operation scheme are to open abdomen exploration of common bile duct, have the shortcomings that wound is big, it is slow to restore.With laparoscope and gallbladder
The development of road mirror technology takes laparoscopic exploration of common bile duct, choledochoscope to take the treatment of liver inside and outside bile duct stone more at present
Stone therapeutic scheme has many advantages, such as that wound is small, restores fast, few intercurrent disease compared with Tradtional laparotomy.
Currently, being placed in choledochoscope from abdominal cavity puncture outfit casing, when carrying out exploration of common bile duct and taking stone, there are all for which
More disadvantages: being both needed to establish pneumoperitoneum in 1. entire surgical procedures, and prolonged pneumoperitoneum is easy to influence the swing of diaphram, influences to breathe
And acid poisoning and ion imbalances can occur for circulation, the absorption of great amount of carbon dioxide, the carbon dioxide of high pressure is through venous return, even
Gas embolism occurs, jeopardizes patient vitals；2. in choledochoscope probe procedure, a large amount of infectivity bile, rubble, gallbladder mud and choledochoscope
Flushing liquor flows into intraperitoneal through notch, is easy to cause abdominal cavity infection, peritoneal abscess, and after rubble and gallbladder mud enter abdominal cavity, it is difficult to
It removes completely, leads to the complication such as abdominal cavity adhesion, intestinal obstruction, internal fistula, peritoneal abscess；3. post-choledochotomy, common bile duct pressure
It reduces and collapses, increase the difficulty that choledochoscope enters choledochus；4. stamp card outer tube is rigid plastics, head end tube wall is easy
Damage choledochoscope.

It is interior；
2. sheath head end is L-shaped, it is placed in choledochus through choledochus notch, there is good fixed function；
3. horizontal tube, bend pipe and vertical pipe are silica gel material, avoid during choledochoscope takes stone and stab card housing tube wall pair
The damage of choledochoscope；
4. sheath head end is L-shaped, the outer tube wall of bend pipe is equipped with through-hole, and choledochoscope can be through the opening and bend pipe on horizontal tube
Through-hole on the tube wall of outer detects lower common bile duct and upper section；
5. after sheath enters choledochus, pneumoperitoneum and laparoscope video can be closed, the concurrent of long-term pneumoperitoneum generation is avoided
The loss of disease and laparoscope system；
6. choledochoscope can be directly entered in choledochus along sheath, and by opening on horizontal tube and bend pipe outer tube wall
Through-hole identification lower common bile duct and upper section direction；
7. water outlet connector connects negative-pressure suction pipe, infectious bile, flushing liquor, muddy stone and gallbladder mud etc. can be discharged
In vitro, it reduces above-mentioned substance and enters complication caused by abdominal cavity.
The utility model can be widely popularized in fields such as medical apparatus based on the above reasons.
