This utility model is when operation; Can the bile duct front end be positioned in the common bile duct through choledochoscope; The intestinal tube front end is placed in the duodenum; When the opening with the external tube portion of drainage tube inserted the opening of external tube portion of return duct, under the pressure effect, bile was drawn from external in return duct is back to duodenum by drainage tube in vivo.Extract the opening of the external tube portion of drainage tube, this moment return duct can to make EA effective.
Further technical scheme is:
Be equipped with the difficult tinsel that is penetrated by X ray in the tube wall of said double hose biliary stent each several part.
Operation when this technical scheme is convenient to perform the operation.
Another improvements are:
Be equipped with the difficult clipped wire that is penetrated by X ray in the tube wall of said double hose biliary stent.
Operation when this technical scheme is convenient to perform the operation equally.
What the metal that is difficult for being penetrated by X ray in above-mentioned two technical schemes was used always is metallic lead.
Another improvements are:
Have side opening on the said bile duct part leading portion sidewall.
Another improvements are:
Have side opening on the said intestinal tube part leading portion sidewall.
Another improvements are:
Said double hose biliary stent disposes guiding tube, and said guiding tube is made up of sleeve pipe and the guide wire that can be built in the sleeve pipe, and the end of said sleeve pipe guiding tube body is pointed end.
This utility model has been realized goal of the invention easily, and is easy to use, alleviates patient's misery greatly, improved patient's life quality, and can avoid causing other diseases.
Description of drawings
Below will combine accompanying drawing and embodiment that this utility model is explained further details:
Accompanying drawing 1 is the structural representation of first embodiment of this utility model.
Each sequence number is respectively in the accompanying drawing 1: 1, the external tube portion of drainage tube; 2, drainage tube stomach tube part; 3, bile duct part; 4, the external tube portion of return duct; 5, intestinal tube part; 6, opening; 7, side opening; 8, lead button; 9, return duct stomach tube part.
The specific embodiment
Referring to accompanying drawing 1; The biliary double hose biliary stent that refluxes shown in first embodiment of this utility model, integral body is the shape that two mutually inverted Y shapes are connected, and is structure as a whole; It comprises drainage tube and return duct; Drainage tube is made up of the external tube portion of the drainage tube that interlinks successively 1, stomach tube part 2 and bile duct part 3, and return duct is made up of the external tube portion of the return duct that interlinks successively 4, return duct stomach tube part 9 and intestinal tube part 5, and the end of bile duct part 2 and intestinal tube part 5 is pointed end; And be equipped with opening 6 and side opening 7; The external diameter of the opening of the opening internal diameter of the external tube portion 4 of return duct and the external tube portion 1 of drainage tube is suitable, and the stage casing tube wall of said drainage tube and return duct is connected and is one, all is equipped with the difficult lead button 8 that is penetrated by X ray in the tube wall of double hose biliary stent each several part.
During operation; Can the bile duct front end be positioned in the common bile duct through choledochoscope; The intestinal tube front end is placed in the duodenum; When the opening with the external tube portion of return duct inserted the opening of external tube portion of drainage tube, under the pressure effect, bile was drawn from external in return duct is back to duodenum by drainage tube in vivo.Extract the opening of the external tube portion of drainage tube, this moment return duct can to make EA effective.
Second embodiment of this utility model uniquely with first embodiment different is in the tube wall of said biliary stent each several part, to be equipped with and to be difficult for the galvanized wire that penetrated by X ray.
The 3rd embodiment of this utility model comprises the external tube portion, stomach tube part, bile duct part, the intestinal tube part that interlink equally, and the each several part bore is 10mm; The head end opening of biliary tract part; Unsharp border, the head section different directions 1cm of being separated by successively has 3 of side openings, and its length is 25cm; External tube portion, stomach tube part intestinal tube part length overall 80cm.Guiding tube is the similar sleeve pipe of external diameter and biliary drainage mouth of pipe footpath, and long 50cm, its head end are slightly thin, blunt circle, the guide line that the center has internal diameter to pass, long 5cm, internal diameter 5mm, built-in guiding steel wire.
Its method for using: common bile is got clean calculus; Biliary tract sound is detected and the clear and definite distal common bile duct of biliary tract microscopy do not have narrow after; Stomach wall puncture at contiguous body of stomach antetheca round ligament of liver leads into the abdominal cavity this biliary stent front end subsequent use; Thrust gastral cavity with special hollow puncture tube (the inner core cast is identical with special biliary stent) at the body of stomach antetheca of nearly round ligament of liver; Insert guiding tube and near pyloric canal gets into the descendant duodenum nipple, extract guide wire in the guiding tube, get into duodenal choledochoscope through common bile duct and nipple the guide line of guiding tube head end is clamped and will be drawn in the common bile duct with the choledochoscope biopsy forceps.The guiding tube end is linked to each other with biliary drainage tube head end, through guiding tube its bile duct is partly drawn in common bile duct, the intestinal tube part is then inserted in the duodenum.The double-deck pocket in the body of stomach antetheca place of thrusting is closed, and closes the gap between other stomach of biliary stent and the round ligament of liver, and stomach wall puncture drainage tube is fixing reliable, and the common bile duct interrupted suture is closed.The open biliary stent of postoperative as required, can partially or completely be opened valve between biliary drainage pipe and bile return duct, so that bile passes back into duodenum, avoids the influence of postoperative bile loss to intestinal mucosa.Behind the normal 5-7 of the postoperative days cholangiography, next day tube drawing.Like the need EA, can implement through the bile return duct, same, biliary stent is retracted in the duodenum, then two-tubely all can be used for the EA support.
Above-mentioned accompanying drawing and embodiment only are used to explain this utility model, and the protection domain of this utility model is not constituted any limitation.
The present invention that above-mentioned structure like this constitutes all has many saving graces for technical staff of the same trade now, and the progressive that possesses skills really.
But, in technical field of the present invention,, can improve other exercisable embodiment of the present invention as long as possess the most basic knowledge.In the present invention substantive technical scheme has been proposed the patent protection request, its protection domain should comprise all variation patterns with above-mentioned technical characterstic.
