Abstract
The utility model discloses a high-efficient microwave intervention curing antenna, which relates to a microwave radiated antenna. The utility model comprises an outer conductor and an inner conductor, which are connected with a socket and a microwave source through a fixing bracket. The utility model is characterized in that the outer conductor is a hollow circular tube taking the inner conductor as the axis center; the free end of the inner conductor extends out of the outer conductor; a medium layer is coated around of the inner conductor; the length for the part of the inner conductor extending out of the outer conductor is 9-30mm.
Description
Technical field:
This utility model relates to a kind of antenna for radiating microwave, particularly a kind of intermitted microwave therapy antenna.
Background technology:
Percutaneous puncture microwave intervention treatment hepatocarcinoma sees Cancer Augustl, 1994, Volume 74, No.3, wherein reported The Department of Internal Medicine, Kansai Medical University, Osaka, Japan.Toshihito Seki, the article of M.D., mentioning the treatment antenna diameter in the literary composition is 1.6mm, about 10mm of ferrule of front end, this treatment antenna advantage is small and exquisite, is applicable to interventional therapy, and shortcoming is A, in use front end 10mm ferrule is fallen easily in hepatic tissue; B, solidification morphology are bad, promptly the microwave thermal field be shaped as spindle, do not match with the shape of cancerous tissue, and solidification morphology is little; C, use inconveniently, for preventing active antenna and tissue adhesion all around, constantly rotary antenna brings very big inconvenience to treatment, and tissue of patient is also produced bigger infringement.
Summary of the invention:
This utility model solves the technological deficiency that above-mentioned intermitted microwave therapy antenna exists, and it is good to design a kind of solidification morphology, integrated micro-wave therapeutic antenna safe and convenient to use.
Technology contents of the present utility model is such: it comprises outer conductor and the inner wire that links to each other with microwave source by fixed support and socket, described outer conductor is one to be the hollow circular tube in axle center with the inner wire, the free end of described inner wire extends outer conductor, the periphery of described inner wire is enclosed with dielectric layer, and the length that described inner wire extends to the outer part of outer conductor is the 9-30 millimeter.
An adherent layer also can be wrapped up in the outside of described outer conductor.
The material of described adherent layer is a politef.
The inboard of described adherent layer also is coated with crome metal.
The length that described inner wire extends to the outer part of outer conductor is 27 millimeters.
Outer conductor of the present utility model is the axle center with the inner wire, it is radiant section that inner wire extends to the outer part of outer conductor, this structure makes internal and external conductor form integral structure, will not make caducous ferrule by radiant section, this can get involved in the body this utility model safely, the length of radiant section is the 9-30 millimeter simultaneously, the solidification morphology that this scope can make this utility model form in treatment is bigger, improve radiation efficiency, and can form and be similar to the spheric radiation thermal field that is complementary with tumor shape, the shape of radiation thermal field and tumor coupling helps to improve the tumor treatment effect.
The outside of this utility model outer conductor is enclosed with one deck adherent layer, can prevent this utility model when intervention is organized with organize adhesion mutually, so rotary antenna prevents adhesion again, thereby make of the present utility model easy to usely, reduce the wound that patient causes because of treatment tool simultaneously.
Description of drawings:
Accompanying drawing is the structural representation of this utility model one embodiment.
The specific embodiment:
1 is the socket that can link to each other with microwave source in the accompanying drawing, be fixed with fixed support 2 on it, the expenditure of fixed support 2 partly is cylindric, card has the piped outer conductor 5 of circle in it, but outer conductor 5 copper pipes, be provided with adherent layer 8 in the outside of outer conductor 5, adherent layer 8 thickness are 0.1 millimeter, mainly constitute by politef, adherent layer 8 is set prevents that metal outer conductor 5 is because of heating and tissue adhesion, one chromium coating 3 also can be set between outer conductor 5 outsides and the adherent layer 8, can make this utility model appearance looks elegant eye-catching.One end of inner wire 4 and outer conductor 5 the same being fixed on the fixed support 2, and all being provided with lead at this end with outer conductor 5 passes fixed support 2 and links to each other with socket 1, the other end is a free end, inner wire 4 length are longer than outer conductor 5, the part that exceeds outer conductor 5 forms aerial radiation part 7, radiant section 7 optimum lengths are 27 millimeters under 60W, the 300S condition of action time, and the solidification morphology that form this moment is 2.6cm * 3.0cm, are an approximate spheroid that is close with the tumor form.Inner wire 4 outer wrapping row dielectric layers 6, dielectric layer 6 are made of politef.
Claims (5)
1. efficient microwave interventional therapy antenna, it comprises outer conductor and the inner wire that links to each other with microwave source by fixed support and socket, it is characterized in that described outer conductor is one is the hollow circular tube in axle center with the inner wire, the free end of described inner wire extends outer conductor, the periphery of described inner wire is enclosed with dielectric layer, and the length that described inner wire extends to the outer part of outer conductor is the 9-30 millimeter.
2. efficient microwave interventional therapy antenna according to claim 1 is characterized in that an adherent layer also can be wrapped up in the outside of described outer conductor.
