This need support the use the radio-frequency ablation electrode of negative plate, higher to the requirement of corollary equipment, and use inconvenient, and negative plate pad is also uncomfortable below human body.
Summary of the invention
The technical issues that need to address of the present invention are: existing radio-frequency ablation electrode, need support the use the radio-frequency ablation electrode of negative plate, higher to the requirement of corollary equipment, and use inconvenient, and negative plate pad is also uncomfortable below human body.
The present invention takes following technical scheme:
A radio frequency ablation electrode device for double-deck umbrella-shaped probes, comprises temperature tube 7, sleeve pipe 5, and it is outside that described sleeve pipe 5 is enclosed within temperature tube 7; Described temperature tube 7 head is tip-like, and first group of probe 8 of its head and umbrella shape is welded and fixed, and uses the first fastener tube 10 to weld fastening with first group of probe 8; In the outside of one section of probe tube 7 at first group of probe 8 rear portion, coating insulation material layer, the outside of described insulation material layer is fixedly connected with second of umbrella shape group of probe 9, and uses the second fastener tube 11 to weld fastening with second group of probe 9; When radio-frequency (RF) energy is passed through, between first group of probe, human body, second group of probe, form current loop; When described radio frequency ablation electrode device does not use, temperature tube 7, first group of probe 8, second group of probe 9 shrinks in sleeve pipe 5 inner; When described radio frequency ablation electrode device uses, temperature tube 7 ejects from sleeve pipe 5 head, and first group of probe, 8, second group of probe 9 struts in umbrella shape.
The feature of the technical program is: the version that have employed double-deck umbrella-shaped probes, simultaneously, again by arranging insulation material layer, make to form insulation between first group of probe and second group of probe, thus radio-frequency (RF) energy is connected mutually by between first group of probe, human body, second group of probe, form current loop, without the need to negative plate.
Further, described radio frequency ablation electrode device afterbody is provided with socket (4), and described first group of probe 8 is also connected with socket 4 by wire, and described second group of probe 9 is also connected with socket 4 by wire.
Further, be provided with temperature sensor in described temperature tube 7, carry out thermometric by described temperature sensor.
Further, the shape of described first group of probe 8 and second group of probe 9, size are identical.
Further, also comprise front bar 1, described front bar 1 is fixedly connected with sleeve pipe 5 rear end, and described front bar 1 is provided with medicine-pouring port 1a, and described medicine-pouring port 1a is communicated with sleeve pipe 5.
Beneficial effect of the present invention is:
1) without the need to supporting the use negative plate, require to decrease to corollary equipment, patient is also more comfortable.
2) radio frequency ablation electrode device uses easier, the restriction not by fixing device during use.
3) double-deck umbrella-shaped probes be arranged so that probe more fully contacts with human body, the better effects if of radio-frequency (RF) ablation.
