Description
Technical field
This utility model relates to a kind of microwave ablation antenna for baby, belongs 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.
At present, microwave ablation antenna is designed by adult, and its external diameter is about 2mm, when baby needs micro-wave therapeutic, just not too applicable.The organ of baby is less, when using the microwave antenna of adult, easily causes organ injury.Therefore, current comparatively conventional way turns down power, but after power reduction, effectively can not kill focus again, easily cause recurrence.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned shortcoming of prior art, provides a kind of microwave ablation antenna being applicable to baby.
In order to solve above technical problem, a kind of microwave ablation antenna for baby that this utility model provides, comprise: insulation tartar, coaxial cable, aqueduct, water blockoff axle, the front end of described coaxial cable is placed in the central blind hole of insulation tartar, is socketed described water blockoff axle and aqueduct outside rear end successively; The afterbody of water blockoff axle and described coaxial cable seal welding, head and the water blockoff axle of aqueduct are welded and fixed, and the external diameter of described insulation tartar is 11.mm to 1.3mm; The front end of described coaxial cable is shaped with emitting head and launch window successively; Described emitting head external diameter is greater than the external diameter of described coaxial cable; Described launch window forms by being set with copper pipe after coaxial cable stripping exocuticle on outer conductor; Described copper pipe and described outer conductor short circuit.
Such scheme further improves and is: described coaxial cable is fixed by glue bond with insulation tartar.
Such scheme further improves and is: described emitting head is the hemispherical that the inner wire that exposes at cable head-end is piled up by scolding tin.
The microwave ablation antenna for baby that this utility model provides, melt antenna compared to tradition, external diameter reduces greatly.Meanwhile, coordinate launch window with emitting head, microwave energy is concentrated on emitting head, form the radiation of point-like, prevent radiation scope large, burn baby organ.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Fig. 1 is the sectional view of this utility model preferred embodiment.
Number in the figure is schematically as follows, and: 1-insulate tartar, 2-outer conductor, 3-coaxial cable, 4-water blockoff axle, 5-aqueduct, 6-emitting head, 7-copper pipe, 8-inner wire.
Detailed description of the invention
embodiment 1
For making the object of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
As shown in Figure 1, the microwave ablation antenna for baby that this utility model provides, comprising: insulation tartar 1, coaxial cable 3, aqueduct 5, water blockoff axle 4; The front end of coaxial cable 3 is placed in the central blind hole of insulation tartar 1, and the external diameter maximum of insulation tartar 1 is 1.3mm; The front end of coaxial cable 3 is shaped with emitting head 6 and launch window successively; Emitting head 6 external diameter is greater than the external diameter of coaxial cable 3; Launch window is peeled off by coaxial cable 3 on outer conductor 2, to be set with copper pipe 7 after exocuticle and to form; Copper pipe 7 and outer conductor 2 short circuit.
Coaxial cable 3 is fixed by glue bond with insulation tartar 1.
Emitting head 6 is hemisphericals that the inner wire 8 that exposes in coaxial cable 3 front end is piled up by scolding tin.
Due in order to adapt to baby's needs, insulation tartar 1 diameter of the present embodiment is less, and therefore, traditional coaxial cable 3 shape originally that only uses just is not suitable for as the scheme of emitting head 6.The present embodiment utilizes copper pipe 7 and outer conductor 2 short circuit, thus effectively shields rear microwave radiation, microwave energy is concentrated on hemispheric emitting head 6 place and carries out radiation, thus avoid radiant body excessive, affected organ, simultaneously, by concentration of energy, effectively sick body can also be killed.
Water blockoff axle 4 and aqueduct 5 is socketed successively outside the rear end of coaxial cable 3; The afterbody of water blockoff axle 4 and coaxial cable 3 seal welding, head and the water blockoff axle 4 of aqueduct 5 are welded and fixed, finally, outside at cover connected water outlet pipe.Like this, aqueduct 5 is intake, and then by the space water outlet between aqueduct 5 and outlet pipe, forms water cycle heat radiation.
embodiment 2
The present embodiment improves on the basis of embodiment 1, and its major part is identical, and different piece is: the external diameter maximum of insulation tartar 1 is 1.2mm, reduces the external diameter of insulation tartar 1 further, and it can be made to be used in less sick body operation.
embodiment 3
The present embodiment improves on the basis of embodiment 2, and its major part is identical, and different piece is: the external diameter maximum of insulation tartar 1 is 1.1mm, further reduces the external diameter of insulation tartar 1, and it can be made to be used in less sick body operation.
In addition to the implementation, this utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of this utility model requirement.
