Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of mother daughter combination formula Y type biliary tract prosthesis.
Background technology
Hilar cholangiocarcinoma (hilar cholangiocarcinoma) refers to occur in left common hepatic duct, right common hepatic duct, left and right common hepatic duct furcation and the cancer of common hepatic duct epimere.Klaskin describe in detail the Clinical symptoms of this type of tumor in nineteen sixty-five.Therefore frequently referred to Klaskin tumor.It is reported that Klaskin tumor accounts for the 58%～75% of cholangiocarcinoma.Tumor location is hidden, and early diagnosis is extremely difficult, and patient is many with Progressive symmetric erythrokeratodermia Huang cellulitis for main performance, is often misdiagnosed as infectious hepatitis.And treated so patient to surgery go to a doctor time for late period, poor prognosis.The treatment means of Malignent Biliary Obstruction is limited at present, surgery radical-ability or expanded resection are unique recoverable therapeutic modalities, but Most patients has been late period when finding, tumor body is big, position is complicated, tumor-infiltrated, surgical procedure is more complicated, and Chang Wufa is fully solved pathological changes, loses surgical radical treatment cutting opportunity, tumor overall operation resection rate is the most relatively low, the most sometimes connects the operation of Palliative Cholangio-jejunostomy and also cannot be carried out.Even and if operation, the probability of postoperative generation liver failure and tumor recurrence is the biggest, and long-term effect is undesirable, and within 5 years, survival rate is less than 5%.
For cannot the obstruction of bile duct patient of surgical resection, biliary tract rack is implanted can the symptom such as reduction of patient Huang cellulitis, pain, pruritus rapidly, preventing and treating cholangitis and cholestatic liver failure, due to often tumor invading bilateral biliary tract, the domestic back-to-back technology of main employing realizes Y type support, or implant one piece of support and sacrifice one lobe of the liver and retain main lobe of the liver, Palliative relief of symptoms, but these technology all cannot meet the anatomical structure of bile duct Y type.Can the double intussusception support of biliary tract although Korea S has listed, but portion support inner wire affects biliary tract long-term drainage, and in order to realize y-type structure combination, wherein has a branch stent mid portion tinsel sparse, tumor recurrence or progress easily block phenomenon again, and follow-up drain extremely bothers.And Korea S's support price is more expensive, it is difficult to universal in China ordinary people.
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of anatomical structure meeting bile duct Y type, and economical and practical mother daughter combination formula biliary tract prosthesis.
The technical solution of the utility model is achieved in that a kind of mother daughter combination formula Y type biliary tract prosthesis, including female support, the submounts being connected with female support assorted, described female support is the netted cavity structure of L-shaped, it is provided with connector in the bending place, inner side of female support, submounts is cylindrical mesh cavity structure, and the lower ending opening diameter of submounts is more than upper end open diameter.
It is equipped with radiopaque labelling at the inner side of described female support and at the lower ending opening circumference of submounts.
The lower ending opening of described submounts docks mutually with connector.
This utility model has following beneficial effect: not only meet the anatomical structure of bile duct Y type, uses simple effects good, and economical and practical, adapts to the economic capability of major part patient, easily universal in China ordinary people；Need not other equipment support, technique successful rate is high, easily popularizes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of mother daughter combination formula Y type biliary tract prosthesis, including female support 1, the submounts 2 being connected with female support 1, described female support 1 is the netted cavity structure of L-shaped, being provided with connector 3 in the bending place, inner side of female support 1, submounts 2 is cylindrical mesh cavity structure, and the lower ending opening diameter of submounts 2 is more than upper end open diameter.Radiopaque labelling 5 it is equipped with at the inner side of described female support 1 and at the lower ending opening circumference of submounts 2.The lower ending opening of described submounts 2 docks with connector 3 phase.
This utility model is when specifically used: female support 1 and submounts 2 all use Nitinol tinsel to work out, and have stronger expansion service and enabling capabilities.One a diameter of 6-8mm of branch of female support 1 of L-shaped, is used for being placed in the branch of two grades of bile ducts in liver, depending on length is according to narrow length, generally 25mm-45mm, a diameter of 10mm-12mm of another branch, is used for putting in common bile duct, depending on length is according to narrow length, general 35-55mm.The upper end diameter of submounts 2 is 6-8mm, and lower end diameter is 8-10mm, depending on length is according to narrow length, and general a length of 25mm-45mm.It is equipped with radiopaque labelling 5, it is simple to position under x-ray at the inner side of female support 1 and at the lower ending opening circumference of submounts 2.
The release tech of this mother daughter combination formula Y type biliary tract prosthesis can have two kinds: 1, unipath release tech: the success of percutaneous transhepatic puncture bile duct, exchange introduces Misgurni anguillicaudati seal wire and conduit, both fit through hepatic hilar region narrow section and enter in common bile duct, radiography confirms, catheter guide wire fits into an other main lobe of the liver and radiography confirms.If it is narrow overweight, it is contemplated that first 8mm-10mm Balloon Angioplasty.Catheter guide wire fits in duodenum, first set up skin-bile duct-duodenum track path, 6F parent stent conveying device is sent into along seal wire, by all labelling points to after good under perspective, the female support 1 of release, the connection oral area making L-type mother's support is just directed at an other bile duct peristome, catheter guide wire enters L-type mother's support connector and enters in an other main bile duct of lobe of the liver, set up skin bile duct track, after send into along seal wire and to discharge after submounts 2, achieve a butt joint, thus form Y type support, meet the anatomical structure of hepatic hilar region.2, dual pathways release tech: seal wire passes through the narrow or inaccessible part of hepatic hilar region, and set up skin-bile duct-duodenum track path, again puncture at another one lobe of the liver and set up manipulating approach, catheter guide wire enters bile duct through this path, enter in common bile duct by stenosis area, sending into female support along seal wire, the connector of L-type mother's support is just directed at another common hepatic duct peristome in liver, and discharges female support.Through the manipulating approach of another one lobe of the liver, catheter guide wire coordinates in this connector enters common bile duct duodenum, sets up second skin-bile duct-duodenum, discharges after this path introduces submounts, it is achieved docking.Thus form Y type support, meet the anatomical structure of hepatic hilar region.
This utility model is not limited to above-mentioned embodiment; according to creative spirit of the present utility model; those skilled in the art can also make other changes; these changes done according to creative spirit of the present utility model; all should be included in this utility model claimed within the scope of, the most this support can also be used for the anatomical structure of three crotch regions in people.
