Description
Technical field
The radioactive particle biliary tract inner drainage tube that carries of the present invention relates to technical field of medical instruments, but is the interior drainage stent of biliary tract in a kind of bearing micro radioactive particle source.
Background technology
At present malignant obstructive jaundice comprises that one group of malignant tumor hepatic portal portion hepatocarcinoma, cancer of biliary duct, cancer of pancreas, carcinoma of ampulla and portal lymph node that causes obstruction of bile duct shifts, oppresses or invade and bile duct etc.Because how this type of case has lost the surgical engine meeting when making a definite diagnosis, excision rate 15%～20% is appeased the partial flow bypass path art and is only applicable to 19% case.Development from phase early 1990s along with the inner support technology, home and abroad extensively adopt ERCP to appease method treatment malignant obstructive jaundice, and clinical effectiveness is satisfied, and make needed the case of simple biliary enteric anastomosis 70% to be replaced by ERCP in the past.But because malignant tumor itself is not effectively treated, restenosis or neoplasm metastasis often take place, the median survival interval of most statistics is 5～12 months, therefore, during the ERCP that is expert at treatment, should carry out the oncotherapy of protopathy as far as possible simultaneously.
Mainly divide two kinds through duodenoscope biliary drainage art, a kind of is bile duct plastic stent drainage (Endoscopic retrograde biliarydrainge under the scope, ERBD), another kind be bile duct metal rack drainage under the scope (Endoscopic biliary metal stent drainge, EBMSD).Preceding a kind of method is at first by German Soehendra report, it is safe and reliable, anacholia is lost, more meet physiological status, postoperative also need not special care, has greatly improved patient's quality of life, simultaneously the malignant tumor patient that advanced age, the biliary tract patient especially can't excise that operation is had a big risk, be a kind of means of palliative therapy preferably, be extensive use of clinical at present.
125I corpuscular radiation source can be positioned over inside tumor or near, tumor tissues can be subjected to heavy dose of radiation exposure around the particle, reach therapeutic purposes, and because the effective irradiation distance of particle is short, the normal surrounding tissue radioactive dose far away from particle obviously reduces, particle is a solid implant simultaneously, does not participate in general metabolism, and is less to the overall health of patients influence.Therefore the 125I internal-radiation therapy can not only reach the therapeutic purposes of kill tumor cell, and to the little advantage of tumor normal surrounding tissue damage, protection normal structure and organ are avoided the ultrahigh dose irradiation.On the other hand, the 125I particle is a kind of radionuclide of lasting low dose exposure, does not have the specific cytosis cycle, and the tumor cell of each phase is all had certain lethal effect, be subjected to the ray prolonged exposure and obviously minimizing thereby make tumor cell breed again, can reduce the recurrence of tumor.
Employing PTCD technology supports such as Bruha are inserted in one group of malignant obstructive jaundice case of binding cavity internal radiotherapy, 1 year survival rate of cancer of biliary duct patient reaches 47%, 1 year survival rate of carcinoma of ampulla patient reaches 75%, and 1 year survival rate of carcinoma of gallbladder patient has then reached 18%, has received good effect.
Malignant obstructive jaundice is the clinical disease that often runs into, but when patient's whole body situation can not tolerate the existing metastasis of radical surgery or tumor, the emphasis of treatment should be and keeps biliary drainage unobstructed, alleviates patient's complication, improves its life quality.But, only go the interior drain (ERBD/EBMSD) of the interior drainage stent of biliary tract also just to the palliative treatment of malignant tumor, be equivalent to drainage.Biliary tract rack implantation associating (125I) radioactive particle intra cavitary irradiation is as a kind of brand-new treatment means, combine the characteristics of ERCP and brachytherapy, combine the advantage of the two, complication that obstruction of biliary tract causes but also the effect of having played treatment had not only been solved, patient's misery is little, quality of life height, the minimizing of exposure dose reduces the side reaction that patient causes because of radiotherapy greatly, really having embodied the theory of minimally-invasive treatment, is the research topic that has development prospect.
Still there is not drainage stent in the biliary tract that can carry (125I) radioactive particle at present.A kind of novel radioactive particle biliary tract inner drainage tube that carries of research design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
