Technical field
The utility model is related to inside and outside a kind of medicine equipment, the single tube ditrysian type biliary tract of particularly a kind of reflowable bile and drawn
Flow tube.
Background technology
Biliary stent is in choledochoscopy, or in the postoperative dilating drainage of cholangiocarcinoma, for drainage
The conventional medicine equipment of bile and supporting drainage road.
When doing operation on biliary tract, abdominal cavity is leak into order to avoid the bile of early postoperation, now using more generally T-shaped
Decompression drainage bile is to external, i.e., opening at one single tube three in pipe insertion choledochus, and it includes external opening successively, and biliary tract is opened
Mouthful and enteron aisle opening, can be by the switch that is open out in vitro, to control inner or outer drainage.The power of interior external drainage depends on completely
Relative pressure size at external pipe, at biliary tract and at enteron aisle.When external section, which is switched, to be opened, when binary passage presyure power is larger,
Bile can flow along the pipe to external pipe with enteron aisle pipe, play the external drainage of bile and interior drainage.Closed when external section is switched
When, be not in external drainage, if binary passage presyure power is more than pressure in enteron aisle, bile can flow to intestinal tube along biliary tract pipe, occur interior
Drainage；When colonic pressure is more than pressure of biliary tract, there is intestinal contents from enteron aisle openend adverse current to biliary tract, cause biliary tract serious
Infection.
The defect of this drainage is：It is not avoided that the adverse current of intestinal juice causes the severe infections in biliary tract, indwelling time is long,
It can just be pulled out after generally needing one day after surgery, fluid electrolyte and digestive ferment is lost therewith, cause Electrolyte imbalance, digested
