Abstract
This utility model relates to a kind of microwave ablation antenna blocking ablation for cancer embolus, belongs to microwave ablation techniques field.This antenna comprises coaxial cable, be fixedly connected on the emitting head of coaxial cable one end and be sleeved on the hands handle of the coaxial cable other end; It is characterized in that: the crust of 12mm and the outer conductor layer of 2mm are removed in one end that coaxial cable connects emitting head, and are set with copper pipe in the outer conductor layer of remainder; Emitting head and inner wire short circuit; The other end of coaxial cable one end is connected with coaxial radio-frequency connector.This utility model 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.
Description
Technical field
This utility model relates to a kind of microwave ablation antenna blocking ablation for cancer embolus, belongs to microwave ablation techniques field.
Background technology
Along with the progress of modern science and technology and oncology, nearly ten years, domestic microwave tumour ablation technology achieves breakthrough anxiety.Microwave tumour ablation utilizes microwave energy affected tissues to produce heat effect, and within the time of several minutes to ten several minutes, its thermal field central temperature can reach more than 100 DEG C, and tumor tissues is solidified under instantaneous high-temperature, deactivation, reaches the object of tumour ablation treating.Microwave tumour ablation art is by the focus of microwave melt needle intervener soma, continues launched microwave energy by its front end, to implement operation, because its efficiency is high, window is little, and to tissue depth of interaction and range size all controlled, be applicable to the ablative surgery of whole body entity tumor.
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
This utility model 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.
In order to solve the problems of the technologies described above, the technical scheme that the utility model 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; 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.
The microwave ablation antenna blocking ablation for cancer embolus that this utility model provides, use 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.
Accompanying drawing explanation
Fig. 1 is this utility model preferred embodiment structural representation.
Number in the figure is as follows: 2-dielectric layer, 3-inner wire, 4-emitting head, 5-coaxial radio-frequency connector, 6-handle, 7-copper pipe.
Detailed description of the invention
Embodiment
The present embodiment block the microwave ablation antenna of ablation as shown in Figure 1 for cancer embolus, comprise coaxial cable, be fixedly connected on the emitting head 4 of coaxial cable one end and be sleeved on the handle 6 of the coaxial cable other end; The crust of 12mm and the outer conductor layer of 2mm are removed in one end that coaxial cable connects emitting head 1, and are set with copper pipe 7 in the outer conductor layer of remainder; Emitting head 1 and inner wire 3 short circuit; The other end of coaxial cable one end is connected with coaxial radio-frequency connector 5.
The top of emitting head 4 is hemispherical, and diameter is 1.3mm.Coaxial cable is semi-flexible cable, and external diameter is 1.3mm.
The antenna that the present embodiment provides utilize the special construction of its front end (emitting head 4, window and copper pipe 7) to get through cancer embolus that current traditional ablation needle can not get through blocks, make cancer embolus treatment in late period have feasible Therapeutic Method safely and effectively.
This utility model is not limited to the concrete technical scheme described in above-described embodiment, and in addition to the implementation, this utility model can also have other embodiments.All employings are equal to the technical scheme of replacing and being formed, and are the protection domain of this utility model requirement.
