Description
Technical field
The present invention relates to the microwave needle for cystocarcinoma tumour ablation treating, 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 treatment of tradition cystocarcinoma tumor can only take the method for performing the operation or injecting chemotherapeutics, operation is because the restriction of condition only has little a part of case to implement, injection chemotherapeutics due to cystic tumor generally all likely exist inside many cell structure, the curative effect of medicine is not good enough, has residual more.The present invention is used to implement the heating of microwave energy to cystic tumor, not only simple but also safely tumor is damaged, simultaneously because the power transfer of microwave is not by the impact of cystic inside tumor compartment, thoroughly can damage tumor, obtain the effect of surgical radical treatment.
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 for cystocarcinoma tumour ablation treating.
In order to solve above technical problem, a kind of microwave ablation antenna for cystocarcinoma tumour ablation treating provided by the invention, include: insulation tartar, pole piece, coaxial cable, aqueduct, water blockoff axle, coaxial radio-frequency connector, handle, described pole piece is placed in the central blind hole of insulation tartar, and rear end and inner conductor are colded pressing and riveted, described water blockoff axle, aqueduct is enclosed within outside coaxial cable successively, the afterbody of water blockoff axle and coaxial cable seal welding, head and the water blockoff axle of aqueduct are welded and fixed, it is characterized in that: also there is the interior pipe be enclosed within outside aqueduct and the outer tube be enclosed within outside described interior pipe, in described, the front end sleeve of outer tube is contained on the rear end boss of insulation tartar, the front portion of described outer tube offers side opening, be fixed with a head between inner and outer pipes and extend capillary tube near described side opening, gap between described aqueduct and coaxial cable forms inlet channel, gap between described aqueduct and interior pipe forms water outlet, .
The microwave ablation antenna that the present invention is used for cystocarcinoma tumour ablation treating also has following feature:
1, the afterbody of described coaxial cable is connected with coaxial radio-frequency connector.
2, have the intake antrum and water chamber separated by water proof circle in described handle, described inlet channel is communicated with water chamber with described intake antrum respectively with the rear portion of water outlet.
3, described intake antrum and water chamber are all provided with and are connected water nozzle fast; Described coaxial radio-frequency connector is also contained in described handle.
4, described interior pipe, outer tube and insulation tartar are fixed by glue bond.
5, pole piece and coaxial cable keep concentric.
6, described diameter of inner pipe is 1.8mm, and outer tube diameter is 2.0mm, and coaxial cable outer conductor diameter is 0.8mm, and coaxial cable outer conductor front end is 12 mm to the distance (exposed dielectric layer length) of pole piece tail end.
Originally melt antenna and be provided with the special injection suction capillary channel being applicable to cystic cancerous protuberance, can be aspirated by this capillary channel during operation, thus meet the ablative surgery needs of cystic cancerous protuberance.Antenna front ends is high efficiency transmitting antenna end, and standing-wave ratio is less than 1.5, can melt fast tumor.The needle point melting antenna is that an ultra sharp relates to, and is easy to the capsule skin punctured in cystocarcinoma.
Very can only take the method for performing the operation or injecting chemotherapeutics to cystic tumor in the past, operation is because the restriction of condition only has little a part of case to implement, injection chemotherapeutics due to cystic tumor generally all likely exist inside many cell structure, the curative effect of medicine is not good enough, has residual more.The present invention is used to implement the heating of microwave energy to cystic tumor, postoperatively extra passage can be utilized capsule liquid and by the aspiration of tissue that melts out, can inject chemotherapeutics strengthens postoperative curative effect simultaneously, such therapeutic process is simple but also safety not only, simultaneously because the power transfer of microwave is not by the impact of cystic inside tumor compartment, thoroughly can damage tumor, obtain the effect of surgical radical treatment.
