Radio frequency plasma ablation operation electrode

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a radio frequency plasma ablation operation electrode. The radio frequency plasma ablation operation electrode provided by the invention comprises a guide tube, a first electrode wire, a second electrode wire, a first electrode tip, a second electrode tip and an insulating sleeve, wherein the first electrode wire and the second electrode wire are arranged in the guide tube, the first electrode tip and the second electrode tip are located at one end of the guide tube, the second electrode tip is of a hollow cylindrical structure and arranged on the periphery of the first electrode tip in a sleeving mode, one end of the first electrode tip is exposed out of an opening in one end of the second electrode tip, and the first electrode tip and the second electrode tip are separated by the insulating sleeve. The radio frequency plasma ablation operation electrode is suitable for ablation of coagulation bleeding points and small-range flocculent tissue under an endoscope and also suitable for large-area and high-power ablation under the endoscope, so that the number of operation electrodes used in the fusion operation process under the endoscope can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a radio frequency plasma ablation operation electrode. Background technique [0002] The endoscopic ablation coagulation electrode currently used in the market has a symmetrical bean-shaped electrode head at the front end of the electrode, and there is a small gap between the two electrode heads, which is only suitable for coagulation of bleeding points and ablation of small-scale flocculent tissues , can not do large-area ablation of other tissue forms. With the development of science and technology, endoscopic surgery is not just a single operation of removing the nucleus pulposus and ablation and coagulation. Endoscopic fusion puts forward higher requirements for ablation and hemostasis electrodes. At present, in order to complete high-quality endoscopic fusion surgery, it is necessary to use different electrosurgical equipment and electrodes matched with various ...
