Abstract
The invention relates to a microwave ablation antenna for interventional treatment of lung cancer. The microwave ablation antenna for interventional treatment of lung cancer comprises a zirconia needling tip, a coaxial cable, a water retaining shaft, a water diversion pipe and a needle rod. The front portion of an outer conductor of the coaxial cable is cut off two spaced sections and exposed with a dielectric layer to form two emitting windows, the outer conductor and an inner conductor of the front end of the coaxial cable are in short circuit through soldering, and epoxy resin glue for fixing is filled between the soldering and a central blind hole of the zirconia needling tip as well as between the dielectric layer at the emitting windows and the central blind hole of the zirconia needling tip. The microwave ablation antenna for interventional treatment of lung cancer is provided with a double-window structure at the head portion to be suitable for the dielectric coefficient of the lung tissue and exactly matched with the lung tissue, has the ablation diameter of more than 5 cm and is an effective tool for ablation of lung cancer, especially large lung cancer.
Description
Technical field
The present invention relates to the microwave ablation antenna being applicable to interventional therapy of lung cancer, belong to microwave melt needle technical 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, wound is little, and to tissue depth of interaction and range size all controlled, be applicable to the ablative surgery of whole body entity tumor.
The existing antenna that melts is single transmit window construction, is applicable to the treatment of the tumors such as hepatocarcinoma.But because boundary's electrostrictive coefficient of cancerous lung tissue and liver, other organs are different, existingly melt the treatment that antenna cannot be applicable to pulmonary carcinoma.And the gross tumor volume of pulmonary carcinoma is large, therefore requires that antenna has and larger melt diameter, this is also that tradition melts antenna and cannot accomplish.And be not also applicable at present operation of lung cancer on the market melt antenna.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of microwave ablation antenna being applicable to interventional therapy of lung cancer.
In order to solve above technical problem, the microwave ablation antenna being applicable to interventional therapy of lung cancer provided by the invention, include: zirconium oxide tartar, coaxial cable, water blockoff axle, aqueduct, shank, described zirconium oxide tartar is provided with axial central blind hole, described coaxial cable inserts in this central blind hole, it is characterized in that: front portion the cutting away two sections and exposing dielectric layer by interval of described coaxial cable outer conductor, form two launch windows, the front end of coaxial cable by soldering by outer conductor and inner wire short circuit, the width range of described two launch windows is 0.9mm-1.1mm, outer conductor length range between two launch windows is 4.1-4.3mm, the tail end of first segment outer conductor is 2.0-2.2mm to the distance range of described soldering front end, between described soldering and zirconium oxide tartar central blind hole, and be filled with epoxide-resin glue between the dielectric layer at launch window place and zirconium oxide tartar central blind hole and realize fixing.
The microwave ablation antenna that the present invention is applicable to interventional therapy of lung cancer also has following feature:
1, described soldering is hemispherical.
2, the diameter range of zirconium oxide tartar and shank is 1.3-1.7mm, and the diameter range of coaxial cable outer conductor is 0.7-0.9mm.
3, preferred, the diameter of zirconium oxide tartar and shank is 1.5mm, and the diameter range of coaxial cable outer conductor is 0.8mm.
4, as preferably, the width of two launch windows is 1mm, and the outer conductor length between two launch windows is 4.2mm, and the tail end of first segment outer conductor is 2.1mm to the distance of described soldering front end.
The dielectric coefficient that antenna is applicable to lung tissue is melted in the present invention, mates lung tissue completely, and for pulmonary carcinoma, particularly melting of large pulmonary carcinoma is a favourable weapon.And the present invention melts antenna with water-cooling system, adding in powerful situation, also can keep the safe and reliable of shank and syringe needle.It is comparatively thin that antenna shank is melted in the present invention, and wound is little, except accommodating except operation of lung cancer, also can be used for the ablative surgery of other tumors.
Originally melt antenna head and offer double-window structure, microwave is outwards launched from two windows, adds and melts size, is suitable for the interventional ablation therapy of lung cancer tumor.The position of emitter window of the present invention and parameter, and the parameter of shank and coaxial cable is important, and The present invention gives an optimum scheme, the territory, effective heating area (ablation range) of this antenna is made to reach more than 5cm, and it is comparatively close circular to burn the shape, and is conducive to the control of operating doctor to operation.
