Plastics biliary tract rack applied for more than 30 years clinically, was a kind of palliative therapy method better can alleviating biliary tract stenosis, but its general pot life is only 3 months, and most of patients need be taken out and implant frame again.1988, self-inflated metal biliary tract rack is applied to clinical, because it has the advantage such as shape memory and super-elasticity, original size can be expanded to voluntarily after metal rack implants narrow biliary tract, and tube wall is produced to the dilating effect continued, and metal rack drainage few intercurrent disease, operative mortality is low, drainage effect is obvious, so metal rack implantation has become the first-selected Therapeutic Method of current Malignent Biliary Obstruction, therapeutic effect for Malignent Biliary Obstruction can reach surgical operation level, but it only can remove obstruction, therapeutical effect be there is no to tumor itself.
In recent years, the research and development of novel enteron support and application development are rapid, and the appearance of biliary tract internal exposure support is overturned support in the past and can only be removed obstruction of biliary tract and to the adiaphorous concept of oncotherapy, impart the New function that support directly can treat malignant tumor.But due to the radiation effects of radioactive particle, its being applied in clinically is restricted to a certain extent; Along with the continuous maturation of scope chemotherapeutic slow-release ion treatment tumor technology, clinical research reports that it has extraordinary curative effect to digestive tract tumor, simultaneously because demonstrating the clinical advantage of its uniqueness in its treatment without the whole body toxicity of conventional chemotherapy, but technique is not yet applied in the middle of pernicious biliary tract at present.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to propose a kind of biliary tract chemotherapy support, integrate expansion biliary tract and local chemotherapy function, not only patient's obstruction of biliary tract symptom can be improved but also can grow at local Tumor suppression after implantation, and the systemic side effects as none caused by chemotherapy, to patient and all radiationless effect of patient, use wound little, there is simple to operate, safe and reliable feature.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of biliary tract chemotherapy support, comprise chemotherapeutic slow-release ion filling capsule 1 and main body rack 2 two parts, described chemotherapeutic slow-release ion filling capsule 1 is cylindrical-shaped structure, and surface is in mesh like, its one end offers the elastic opening 3 for placing chemotherapeutic slow-release ion, and the other end is enclosed construction; Described main body rack 2 is hollow screw shape framing structure, and particle chemical therapy filling capsule 1 is fixed on main body rack 2 outer surface.
