Description
Technical field
This utility model relates to Medical rack field, especially a kind of portability internal radiation particle apparatus and mfg. moulding die thereof, and this utility model relates to a kind of biliary tract stenosis that not only can make and expands but also have device tumor of biliary tract being carried out to radiotherapy.
Background technology
As everyone knows, the traditional Therapeutic Method of cancer of biliary duct is surgical operation, but only there is the tumor possibility excision of 20%, for can not the person of excision, biliary enteric anastomosis or the palliative treatment of biliary tract T pipe external drainage art can be selected, although this treatment can efficient solution except blocking, improving clinical symptoms, but also there are some problems, as operating difficulty is large, early complication is many, postoperative biliary tract infection etc., therefore palliative operation method curative effect is bad, wound is large, and life quality is low, and cancer of biliary duct is one of difficult problem of surgical intervention all the time.
Utility model in 1979 application scope ERCP places biliary tract plastics inner through vater's papilla and supports extension fixture treatment biliary tract stenosis and succeed, become a kind of good palliative therapy method of effect alleviating cancer of biliary duct, there is the advantages such as wound is little, few intercurrent disease, determined curative effect, the jaundice of patient can be removed, improve overall health of patients, but it is 3 months that plastics inner supports the extension fixture general operating period, and after more than 6 months, most of support can block, and need take out Stent Implantation again.Under scope, plastic stent inserts the complication of biliary drainage art primarily of pancreatitis, antidromicity biliary tract infection and stent migration or obstruction.
Along with the development of scope and interventional radiology, utilize ERCP or the PTCD method treatment cancer of biliary duct of Wicresoft, change external drainage is interior drain, simple to operate, achieves better therapeutic effect, China also last century the nineties carry out gradually.Metal rack biliary drainage art wound is little, with the implantable larger-diameter support of thinner conduit, early complication is few, operative mortality is low, metal inside supports after extension fixture inserts narrow biliary tract can diffuse into original diameter certainly, narrow tube wall is produced to the expansionary force continued, keep the stability of support.
Stent in the treatment treats the narrow better method of cancer of biliary duct at present, but along with the application of new technique, the application of current biliary tract rack has had some limitation, and such as existing support as palliative treatment, can only allow of no optimist to the late result of cancer of biliary duct always.If therefore can local radiotherapy be targetedly carried out while stent-expansion, the toxic and side effects of body irradiation can be lowered, better effect can be had to treatment again.
