Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of embedded type biliary tract endoprosthesis completely.
Background technology
Clinician, when treating the patient of obstructive jaundice, usually needs to use biliary drainage device.The biliary drainage device used in current clinical position comprises biliary stent and biliary tract rack.These two kinds of biliary drainage devices prove there is following drawback by Clinical practice: 1, biliary drainage interface tube is positioned at patient body-surface, need to cover dressing, easily infect, cause patient to carry inconvenience, affect the quality of life of patient, the psychological burden of making patients.2, biliary tract rack is implanted, then without the need to retaining biliary extra-drainage pipe as selected.But it is large that biliary tract rack implants difficulty, costly, the status requirement fixing to support is strict, once after implanting, cannot adjusting pole position, and cannot take out and reclaim.3, along with the growth of tumor, the problem of support upper and lower side restenosis may be there is, cause biliary tract again to block, often need to continue to implant biliary tract rack, form the situation of support inner sleeve support, cause local biliary tract expansion insufficient.4, after implanting biliary tract rack, as there is cholestasis, cannot rinse.5, after implanting biliary tract rack, as merged biliary tract infection, vein uses antibiotic weak curative effect, and the infection site antibiotic valid density in biliary tract is lower, is unfavorable for infection control.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides one to imbed subcutaneous, reduces infection rate; The length of body can regulate, and can be suitable for different building shape patient, and all spendable a kind of separation preventing biliary tract endoprosthesis of left and right common hepatic duct.
In order to reach above object, technical solution adopted in the utility model is: this kind of separation preventing biliary tract endoprosthesis is made up of pedestal and endoprosthesis conduit.It is characterized in that: 1. pedestal is embedded in subcutaneous, impact faces is the barrier film be made up of silica gel, and centre is reservoir, and silicone skirt can tolerate the puncture of not damaged puncture needle, and there is metal spigot the side of pedestal, and this socket can be connected with the epimere of endoprosthesis.2. endoprosthesis conduit comprises epimere, stage casing and hypomere composition, endoprosthesis conduit is hollow structure, and tube wall includes the roentgenopaque material of wired sample, and the epimere of endoprosthesis conduit inserts in the interface of pedestal, there are 5 side openings in stage casing, the two ends tube wall of endoprosthesis conduit stage casing side opening has metal marker thing respectively, can locate under x-ray, endoprosthesis conduit hypomere is pigtail-shaped, and have 5-8 side opening, be positioned in duodenum.The bile deposited because of obstruction of biliary tract in stones in intrahepatic bile duct enters endoprosthesis by the side opening in stage casing, enters intestinal by the side opening of section far away.
Described biliary tract endoprosthesis pedestal, body is made up of medical resin material, and barrier film is made up of medical silica-gel, and socket is made up of metal material.Drainage tube material is that polyureas ammoniacum makes, and this utility model material therefor has good biocompatibility.
Preferably, biliary tract endoprosthesis pedestal is truncated cone-shaped, is highly 0.5cm-1.5cm, and its smaller diameter end is upper bottom surface, and the external diameter of upper bottom surface is about 1.0cm-1.5cm, and optimum is 1.5cm; , its larger diameter end is for being bottom surface, and bottom surface external diameter is 2.0cm-2.5cm, and optimum is 2.5cm, and silicone skirt is positioned at the upper bottom surface of round platform, and during embedding, upper bottom surface barrier film side is near skin, so that puncture.
Preferably, the stage casing of endoprosthesis conduit is about 4cm-6cm, has 4-6 side opening, optimum is 5, and 5mm place, side opening both sides respectively has length to be about 3mm metal marker district, can develop in this region under x-ray, during implantation, through perspective, the stage casing of endoprosthesis conduit can be positioned in stones in intrahepatic bile duct.
Preferably, endoprosthesis conduit hypomere is about 3cm-5cm, and in pigtail-shaped, have 3-5 side opening, optimum is 4.
Preferably, the external diameter of endoprosthesis conduit is 2.64mm-8.58mm (i.e. 8F-26F).
This utility model can make different specifications and models as required.
Operational approach of the present utility model is: under X-ray examination, first puncture needle percutaneous puncture stones in intrahepatic bile duct is used, limit puncture marginal not enters contrast agent, as stones in intrahepatic bile duct development, then send into seal wire along puncture needle, exit puncture needle, convergent divergent channel is sent into along seal wire, successively expand subcutaneous, exit convergent divergent channel, endoprosthesis conduit is sent into along seal wire, under perspective, section far away for endoprosthesis conduit is passed through biliary tract stenosis section, and along stones in intrahepatic bile duct, common hepatic duct, common bile duct sends into duodenum, revise catheter position subsequently, ensure that two, endoprosthesis conduit stage casing metal marker is placed in stones in intrahepatic bile duct.Around endoprosthesis conduit skin penetrating point, do 2cm otch subsequently, subcutaneous blunt separation, makes pocket, imbeds endoprosthesis pedestal, and inserts in the endoprosthesis interface of pedestal after endoprosthesis conduit epimere is cut off external exposed part.Last skin suture.To in the successive treatment of patient, not damaged lancet puncture barrier film can be used, carry out cholangiography, biliary culture, biliary tract flushing and Drug therapy.As need endoprosthesis be removed, then cut skin, be separated pedestal, and extract endoprosthesis.
This use is novel to have the following advantages:
1. this utility model is implanted conveniently, implants biliary stent, only need X-ray examination or ultrasound guided puncture to enter liver without the need to opening operation abdomen, and implant approach identical with conventional percutaneous transhepatic cholangiography and drainage art, can complete under local anesthesia, patient tolerability is good.
2. arrange endoprosthesis pedestal to be conducive to: after 1. endoprosthesis implants, without external exposed part, reduce the risk that external environmental factor causes catheter-related Infections: Clinical Study, time of carrying more conventional bile duct internal and external drainage Guan Gengchang.2. the biliary tract endoprosthesis implanted completely, without the need to adjuvant parcel, more attractive in appearance, improve patient tolerability, be more vulnerable to female patient and welcome.3. easy to maintenance, use weekly normal saline to rinse endoprosthesis through not damaged puncture needle, prevent cholestasis; As there is biliary tract infection, antibiotic therapy biliary tract infection can be injected through the silicone skirt of the pedestal that punctures; As needed biliary culture, by not damaged lancet puncture pedestal, bile sample can be obtained.4. follow-up cholangiography inspection is beneficial to, without the need to again setting up puncture channel.5. tube drawing is convenient, after only needing local anesthesia, after being separated endoprosthesis pedestal, equally can pull out with conventional drainage tube.
3. endoprosthesis pedestal is truncated cone-shaped, imbeds subcutaneous, is conducive to medical personnel and punctures fixing.
4. there is metal marker at drainage tube side opening two ends in endoprosthesis conduit stage casing, are positioned in stones in intrahepatic bile duct under being convenient to X-ray examination.
The beneficial effects of the utility model are: a kind of embedded type biliary tract endoprosthesis structure is simple completely, use safety, overcome the existing drawback easily causing infection with external biliary stent, avoid after biliary tract rack is implanted simultaneously and cannot carry out the problem that biliary tract rinses drawn game portion dabbling drug; Can for clinical biliary drainage.
