Abstract
The utility model discloses a dilating balloon catheter for a narrow biliary tract and a biliary-intestinal anastomotic stoma. The dilating balloon catheter comprises a single-cavity catheter part (6), a double-cavity catheter part (7), a balloon (3), a main papilla (9), an auxiliary papilla (8), a bile drainage hole (2) and a water and gas injection hole (5). The dilating balloon catheter is characterized in that the length of the single-cavity catheter part is subjected to that the single-cavity catheter part can penetrate through the liver and the abdominal wall in vitro and can fully drain bile and operate the catheter. In order to be convenient for the placement of a guide steel wire and bile drainage, the surface of the catheter and an inner cavity are coated with ultra-smooth coatings (1). In order to conveniently position the balloon during operation, a material (4) which is obviously visible under X ray and B ultrasound is embedded in the middle wall of the balloon. When the balloon shifts, the part of the catheter in vitro can be dragged to enable the balloon to return. When the balloon is ruptured, the dilating balloon catheter for the narrow biliary tract and the biliary-intestinal anastomotic stoma can be replaced through the guide steel wire.
Description
Technical field
Relate to-kind of medical apparatus and instruments of this utility model, relate in particular to-kind of narrow biliary tract and gallbladder intestinal anastomotic stoma expansion of balloon catheter.
Background technology
As everyone knows, the main bile duct of Hilar causing due to biliary duct injury and liver transplantation narrow is one of thorny problem of Genneral Surgery.Process the generation that bad meeting causes stomachache, biliary tract infection, jaundice, liver function to be badly damaged, and cause thus narrow bile duct far-end to form calculus of intrahepatic duct widely.Be further development of biliary cirrhosis and portal hypertension, finally cause patient's death.Even also have a lot of patients to be difficult to arrive satisfied therapeutic effect to the capable biliary enteric anastomosis of damage bile duct.Because As time goes on and again gallbladder intestinal anastomotic stoma can become narrow.
To the biliary tract stenosis after biliary duct injury and liver transplantation, existing treatment technology comprises placed cavity inner support pipe, lays memory metal support and does disposable expansion etc. by duodenoscope to placing dilating sacculus in biliary tract in stenosis.But clinical practice shows, these methods have corresponding shortcoming to be difficult to satisfied processing biliary tract stenosis problem.In the recent period, a kind of method of new gradual biliary tract expansion is used to the clinical satisfied curative effect that obtained.Its principle is exactly in biliary tract, to place dilating sacculus by the method for operation, and after surgery a period of time narrow bile duct is implemented to be interrupted, gradual expansion, the effect that reaches expansion biliary tract can not make again biliary tract necrosis due to long-time pressurized.It is exactly that conduit before sacculus is too short that but this sacculus has a larger shortcoming, after placing, is easily shifted.Particularly for gallbladder intestinal anastomotic stoma, because the wriggling of intestinal makes sacculus be easy to after surgery to depart from the position of anastomotic stoma and ineffective.And, once just be difficult to again it be put back to original position when sacculus departs from operating position, cause operative failure.In addition, even if sacculus is not shifted, if the damage but sacculus occurs breaking etc. during treating will thoroughly lose the effect for the treatment of, the foley's tube that is difficult to more renew is to narrow positions.
Utility model content
The purpose of this utility model is to provide in order to overcome the deficiencies in the prior art-kind can be used for to narrow bile duct carry out for a long time, narrow biliary tract and the gallbladder intestinal anastomotic stoma expansion of balloon catheter of rule, gradual expansion.Narrow biliary tract and gallbladder intestinal anastomotic stoma expansion of balloon catheter comprise single lumen catheter portion, double channel catheter portion, sacculus, main nipple, additional teat, biliary drainage hole, water filling injecting hole, and the length of single lumen catheter portion is passing external and can be as the criterion with operation conduit by abundant bile drainage through liver and stomach wall.
For the ease of inserting and biliary drainage of guiding steel wire, catheter surface and inner chamber all scribble superslide coating.
For the ease of in operation to sacculus location, sacculus middle wall be embedded with one under x-ray and B ultrasonic obvious visible material.
Can find out from the technical solution of the utility model, because the length of single lumen catheter is enough to pass external through liver and stomach wall, if sacculus occurs during dilation therapy to break can not implement the situation of expansion time, superslide steel wire can be inserted to conduit through main tube cavity again, be passed by other end opening.Exit the conduit having damaged, retain steel wire.Insert a new conduit by steel wire, extract steel wire.After sacculus being positioned by x-ray radiography or B ultrasonic, conduit is fixed at abdomen wall sewing.As find sacculus displacement, and drag conduit part in vitro, make sacculus come back to narrow bile duct, in general can allow sacculus central authorities just to stenosis of bile duct place.Adjusting position rear tube can sew up fixing at stomach wall again.Reach goal of the invention of the present utility model completely.
Brief description of the drawings
Fig. 1 is the structural representation of the narrow biliary tract of this utility model and gallbladder intestinal anastomotic stoma expansion of balloon catheter.
Fig. 2 is the using state figure of the narrow biliary tract of this utility model and gallbladder intestinal anastomotic stoma expansion of balloon catheter.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1, referring to accompanying drawing 1, narrow biliary tract and gallbladder intestinal anastomotic stoma expansion of balloon catheter comprise single lumen catheter portion 6, double channel catheter portion 7, sacculus 3, main nipple 9, additional teat 8, biliary drainage hole 2, water filling injecting hole 5, and the length of single lumen catheter portion is passing external and can be as the criterion with operation conduit by abundant bile drainage through liver and stomach wall.For the ease of inserting and biliary drainage of guiding steel wire, catheter surface and inner chamber all scribble superslide coating 1.For the ease of in operation to sacculus location, sacculus middle wall be embedded with one under x-ray and B ultrasonic obvious visible material 4.
Claims (3)
1. a narrow biliary tract and gallbladder intestinal anastomotic stoma expansion of balloon catheter, comprise single lumen catheter portion (6), double channel catheter portion (7), sacculus (3), main nipple (9), additional teat (8), biliary drainage hole (2), water filling injecting hole (5), it is characterized in that: the length of single lumen catheter portion is passing external and can be as the criterion with operation conduit by abundant bile drainage through liver and stomach wall.
2. the narrow biliary tract of one according to claim 1 and gallbladder intestinal anastomotic stoma expansion of balloon catheter, is characterized in that: for the ease of inserting and biliary drainage of guiding steel wire, catheter surface and inner chamber all scribble superslide coating (1).
3. the narrow biliary tract of one according to claim 1 and gallbladder intestinal anastomotic stoma expansion of balloon catheter, is characterized in that: for the ease of in operation to sacculus location, sacculus middle wall be embedded with one under x-ray and B ultrasonic obvious visible material (4).
