Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to one kind for carry radioactive particle and tumor suppression because
The bracket of son.
Background technique
Radical surgery excision is that (cancer of the esophagus, cholangiocarcinoma, tumour in enteron aisle are intratracheal swollen for tumour in most of cavity
Tumor, intravascular cancer embolus, carcinoma of ureter etc.) primary treatment scheme, but when most patients are medical, often has occurred and that local leaching
Profit and DISTANT METASTASES IN and radical treatment can not be received.Bracket is often used to open obstruction organ such patient, to improve
Patients ' life quality, such as cancer of the esophagus malignant obstruction are implanted into Esophageal Stent, and Malignant Biliary Obstruction is implanted into biliary tract prosthesis, malignant intestinal
Obstruction implantation intestinal stent, tracheae malignant obstruction are implanted into trachea bracket, intravascular malignant obstruction implantable intravascular bracket, and ureter is disliked
Property obstruction implantation ureter bracket.But these brackets only have the function of opening normal lumina, and can not treat tumour, tend to vary with
The growth of tumour cause in bracket and the blocking of bracket both ends.
Radioactive particle oesophagus, trachea bracket, biliary tract prosthesis can be carried by clinically having had, and clinically be achieved
Good curative effect, but since implantation conveyer diameter is too big, the especially narrow hollow organ such as bile duct, ureter, radioactivity
Particle bracket can not complete primary implantation by conveyer, but the method for using intussusception, first piece of bracket are to carry radioactivity
The wire of particle, second piece is ordinary stent, and double bracket is implanted into the pain for not only increasing patient, also improves implant procedure
Expense.Therefore designing a kind of integrated function bracket has good potential applicability in clinical practice.
Utility model content
The purpose of the utility model is to provide a kind of for carrying the bracket of radioactive particle and tumor suppressor, solves mesh
Fore-stock treats the problem of tumor effect difference and inconvenient implant procedure.
The utility model the technical scheme adopted is that a kind of for carrying the bracket of radioactive particle and tumor suppressor,
Including bracket, the bracket includes rack body, and the rack body is the cylinder l network bone worked out by Nitinol
Frame structure, described rack body the inner surface and the outer surface are equipped with coating layer, and slow release layer, the branch are coated on the coating layer
Frame ontology is circumferentially uniformly provided with a plurality of groove being axially arranged, and is fixedly connected with and puts along the groove length direction in the groove
The sub- storehouse of radion.
The utility model is also characterized by the radion storehouse suture is in the groove.
The utility model is also characterized by the radion storehouse is the tubulose knot being fabricated by plastics heat-shrink tube
Structure.
The utility model is also characterized by radion storehouse quantity is 4~6.
