Abstract
The utility model relates to an air-bag type artificial bile duct which is composed of an air bag, a jacket-type bile duct and an inflating bag. In clinical application, the air bag is arranged in the subphrenic space of a liver; through breathing exercises, air in the bag is extruded, and thus the bile duct crawls; the inflating bag is arranged under skin to be easy for inflation when necessary and can be used for visualization. The air-bag type artificial bile duct which is in accordance with physiological pathways has good compatibility with the tissues of a human body; the utility model can prevent retrograde infection and cholestasis.
Description
This utility model relates to a kind of artificial organ.
Reparation problem after the common bile duct excision is one of main difficult problem of biliary surgery.The mode of biliary tract reparation for many years mainly contains three classes: 1, substituting from the body jejunum.The most frequently used is, and jejunum Roux-Y coincide, and other also has jejunum rectangle lobe to coincide, and puts intestinal anastomosis or the like mode.The common drawback of this class art formula is not meet physiological pathway.2, from other tissue substitute of body.Femoral vein, vermiform appendix, skin or the like are as choledoch-substitute, but its common drawback is to prevent retrograde infection, cause the alluvial of gallbladder mud easily.3, synthetic material prosthese.Have silicone rubber and teflon catheter to do biliary tract, but be single pipeline configuration, can not prevent retrograde infection and cholestasis, histocompatibility is poor.
The purpose of this utility model is to provide a kind of artificial choledochus that can prevent retrograde infection.
The bladder-type artificial choledochus is made up of three parts: air bag, jacket type artificial choledochus, gas injection capsule, adopt the medical grade polyurethane thermoplastic elastomer (TPE) to manufacture.Air bag (1) is linked to each other with bile duct overcoat (5) by airway (3), and bile duct overcoat opposite side links to each other with gas injection capsule (8) by another airway, and bile duct (6) passes the bile duct overcoat, and bile duct and bile duct overcoat are not connected.Young on the bile duct, end opening is big, the terylene ring (4) that connects suitable for reading, and end opening connects down terylene ring (7).In practical clinical, air bag places the liver subphrenic space, last terylene ring and hepatic duct end-to-end anastomosis, and following terylene ring and duodenal wall end coincide.The gas injection capsule is embedded in subcutaneous.
The bladder-type artificial choledochus meets physiological pathway, adopt the polyurethane material and the tissue compatibility good, air bag moves with diaphram, make bile duct have the motion of similar wriggling by gas in the capsule, has sphincter function, can prevent retrograde infection and cholestasis, the gas injection capsule is embedded in subcutaneous be easy to radiography and mediation.
Accompanying drawing 1 is the profile of bladder-type artificial choledochus provided by the utility model.
Below in conjunction with accompanying drawing bladder-type artificial choledochus provided by the utility model is described further:
Air bag (1) outer rim has fixed edge (2), so that fixing in vivo the stitching, air bag is made flat crescent with medical grade polyurethane, so that put in vivo.Airway (3) is communicated with air bag and bile duct overcoat (5), and by respiratory movement extruding diaphragm lower gasbag, and conducting pressure is to the bile duct overcoat, and then extruding bile duct (6) forms creeping effect, thereby discharges bile, and prevents that intestinal contents from backflowing and reverse infection.Bile duct passes the bile duct overcoat, and not connected with overcoat.Young and join on the bile duct with last terylene ring (4), with the hepatic duct end-to-end anastomosis, the bile duct end opening is big and join with following terylene ring (7), is used for the duodenal wall end identical.Gas injection capsule (8) also is communicated with the bile duct overcoat by airway, and the gas injection capsule is embedded in subcutaneous, is used for make-up gas in case of necessity, also can be used for radiography and mediation.
Claims (1)
1, a kind of bladder-type artificial choledochus, it is characterized in that: it is made up of air bag, jacket type artificial choledochus, gas injection capsule three parts, air bag (1) is linked to each other with bile duct overcoat (5) by airway (3), bile duct overcoat opposite side links to each other with gas injection capsule (8) by another airway, bile duct (6) passes the bile duct overcoat, and not connected with overcoat, young and connect terylene ring (4) on the bile duct, end opening is big and connect down terylene ring (7).
