Description
Technical field
This utility model relates to a kind of conduit, more particularly, relates to the conduit that a kind of biliary tract is used.
Background technology
Calculus of bile duct is very common disease, and calculus of intrahepatic duct is a type of calculus of bile duct, refers to the calculus in above each the branch bile duct of left and right sides conjunctive region of hepatic duct.
Numerous studies show that is the goldstandard of present treatment calculus of bile duct of generally acknowledging through scope Retrograde cholangiopancreatography (ERCP, Endoscopic Retrograde Cholangio-Pancreatography).
As everyone knows, because the end of common hepatic duct is divided into left common hepatic duct and right common hepatic duct, after the ERCP patient finishes the operation such as common bile duct cannula angiography, sometimes because left and right sides stones in intrahepatic bile duct pathological changes then needs to carry out optionally left and right sides common hepatic duct radiography, gets the operations such as stone, support implantation, need to reboot other apparatuses and enter to finish further operation this moment by placing first seal wire target approach bile duct.
Existing radiography equipment (comprise pull-type incision knife, angiography catheter, get the stone sacculus) all can not be adjusted self direction, finish optionally left and right sides common hepatic duct radiography, get the operations such as stone, support implantation such as need, can only repeatedly adjust the selection that the scope shank degree of depth changes duct direction or guides to finish direction by the bounce-back of seal wire by the patient, this not only needs the patient to have rich experiences but also the long x-ray exposure of needs, therefore, such complicated operation, waste time and energy, difficulty is large, and the success rate of operation is lower.
Summary of the invention
The technical problems to be solved in the utility model provides the conduit that a kind of biliary tract is used, the conduit that this biliary tract is used can change according to actual needs catheter proximal end towards, be inserted in the left common hepatic duct of human body or in the right common hepatic duct thereby be convenient to conduit.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
The conduit that a kind of biliary tract is used is characterized in that: comprise trocar sheath and two air bag direction-control apparatus, above-mentioned pair of air bag direction-control apparatus comprises left injecting hole, right injecting hole, left air bag, right air bag, left appendix and right appendix; Above-mentioned left injecting hole is located on the left side of trocar sheath front end, and above-mentioned right injecting hole is located on the right side of trocar sheath front end; Be located on the left side of trocar sheath front end above-mentioned left air sac sealing, be located on the right side of trocar sheath front end above-mentioned right air sac sealing, above-mentioned left air bag is communicated with left injecting hole, and above-mentioned right air bag is communicated with right injecting hole; Above-mentioned left appendix and right appendix are located at respectively in the trocar sheath, the front end of above-mentioned left appendix and right appendix is the gas outlet, the gas outlet of above-mentioned left appendix is installed on the left injecting hole, the gas outlet of above-mentioned right appendix is installed on the right injecting hole, extend the respectively outside of sleeve pipe its rear end, the rear end of above-mentioned left appendix and right appendix, the rear end of above-mentioned left appendix is connected with left air inlet union joint, and the rear end of above-mentioned right appendix is connected with right air inlet union joint.
