ELECTRODE TIP FOR RADIOFREQUENCY TISSUE ABLATION AND ELECTRODE HAVING THE SAMEThe present invention relates to an electrode tip for radiofrequency tissue ablation and an electrode, wherein a hollow portion and an outlet, through which the saline solution introduced into the hollow portion is introduced into the living body, are formed in the electrode tip to cool the electrode tip with the saline solution, while allowing the saline solution to flow into the tissue to increase electrical conductivity to prevent carbonization of the tissue, which makes it possible to cauterize the tissue in a relatively larger area within a shorter time or with a higher output.
