Description
Technical field
This utility model belongs to field of medical appliances, and relate to modern medicine and carry out scope Wicresoft and protect a kind of core medical instrument that gallbladder is got the stone operation, specifically be a kind of soft, hard child and mother gall bladder, bile speculum system and using method thereof.
Prior art
Cholelithiasis is the commonly encountered diseases and the frequently-occurring disease of China, and cholelithiasis not only only is present in gallbladder, also may betide cystic duct, stones in intrahepatic bile duct, extrahepatic bile ducts.It is reported that China's cholelithiasis merges the 6%-10% that the choledocholithiasis sickness rate accounts for cholelithiasis.In the treatment, the treatment that cholelithiasis merges choledocholithiasis is the difficult point of biliary tract surgery.The treatment cholelithiasis merges choledocholithiasis and mainly contains three kinds of modes: the one, and gallbladder removal+exploration of common bile duct (peritoneoscope descends or opens abdomen and carry out); The 2nd, gallbladder removal+ERCP (ERCP: endoscopic retrograde cholangiopancreatography (ERCP).Being to inject contrast agent through the vater's papilla intubate under scope, showing pancreaticobiliary shadowgraph technique thereby drive in the wrong direction, is the goldstandard of present diagnosis diseases of pancreaticobiliary duct of generally acknowledging.) (peritoneoscope or open abdomen and carry out); The 3rd, scope is protected gallbladder and is got stone+ERCP.With the shortcoming of the two kinds of methods of going forward is to be cost with the excision gallbladder, the shortcoming of the third method is a trivial operations, it generally all is to be used by the sub-mirror of hard shank and female mirror, because the inflexibility of the work end of the sub-mirror of hard shank, very difficult it is entered in common bile duct, common hepatic duct and the hepatic portal portion left and right sides common hepatic duct got stone, calculus to common hepatic duct and hepatic portal one secondary bile duct can not thoroughly be removed, and has certain post-operative complication.
The utility model content
The purpose of this utility model is to overcome prior art can not merge choledocholithiasis disease by fine solution cholelithiasis, propose a kind of being applicable to and solve soft, hard child and mother gall bladder, bile speculum system and the using method thereof that cholelithiasis merges choledocholithiasis simultaneously, this soft or hard child and mother gall bladder, bile speculum system can enter common bile duct, common hepatic duct and hepatic portal portion left and right sides common hepatic duct, get treatments such as stone, can more completely calculus be removed clean, therapeutic effect is good, and the post-operative complication probability is few.
In order to realize above-mentioned technical purpose, this utility model is achieved through the following technical solutions:
