Existing ablation techniques, comprises microwave ablation, in the face of having invaded the cancer embolus of blood vessel or bile duct, ductus pancreaticus, not having can the apparatus of ablation and method, current patient is not because have Therapeutic Method safely and effectively, and life cycle is very short and life quality is poor, is badly in need of clinically solving this difficult problem.
Summary of the invention
The present invention wants technical solution problem to be: the shortcoming overcoming above-mentioned technology, provides one to can be used for cancer embolus and block ablation microwave ablation antenna and manufacture method thereof.
In order to solve the problems of the technologies described above, the first technical scheme that the present invention proposes is: a kind of microwave ablation antenna blocking ablation for cancer embolus, comprises coaxial cable, is fixedly connected on the emitting head of described coaxial cable one end and is sleeved on the handle of the described coaxial cable other end; The crust of 12mm and the outer conductor layer of 2mm are removed in one end that described coaxial cable connects described emitting head, and are set with copper pipe in the outer conductor layer of remainder; Described emitting head and described inner wire short circuit; The other end of described coaxial cable one end is connected with coaxial radio-frequency connector.
Such scheme further improves and is: the top of described emitting head is hemispherical.
Such scheme further improves and is: described coaxial cable is semi-flexible cable, and external diameter is 1.3mm.
Such scheme further improves and is: the diameter of described emitting head is 1.3mm.
In order to solve the problems of the technologies described above, the second technical scheme that the present invention proposes is: a kind of manufacture method of blocking the microwave ablation antenna of ablation for cancer embolus, comprises the steps:
(1) inner wire is exposed in the stripping of the crust of one end of coaxial cable, outer conductor layer and dielectric layer;
(2) crust of 12mm and the outer conductor layer of 2mm are peeled off in the one end of exposing inner wire, and the outer conductor layer exposed is fixed;
(3) copper pipe is sleeved in the outer conductor layer exposed also fixing, the inner wire exposed makes emitting head;
(4) other end of coaxial cable is removed the outer conductor layer of one section of crust and 2mm, then coaxial radio-frequency connector is connected on it;
(5) handle is fixedly mounted on the other end of coaxial cable.
Such scheme further improves and is: in step (3), emitting head is made up of scolding tin, and its top is hemispherical, and the diameter of described emitting head is 1.3mm.
Such scheme further improves and is: in step (1) and step (4), and the fixing means of employing is welding.
Microwave ablation antenna and manufacture method thereof of blocking ablation for cancer embolus provided by the invention, it uses microwave energy, by the antenna radiator that emitting head, window and copper sheathing are formed, the tumor tissues of artery-clogging or bile duct, ductus pancreaticus is melted damage, get through thromboembolism, thus the life of patient and quality of making the life better can be extended, make cancer embolus treatment in late period have feasible Therapeutic Method safely and effectively, clinical meaning is great.
