ELECTRODE DEVICE FOR RADIO FREQUENCY ABLATION

摘要

Disclosed is an electrode device for radio frequency ablation for enabling precise operation by accurately measuring the temperature of a cauterized part. The electrode device for radio frequency ablation is inserted into the body tissue and then cauterizes a lesion region using radiated radio frequency waves, wherein the electrode device for radio frequency ablation comprises: an electrode needle comprising an electric transfer portion connected to an electrode line supplying radio frequency waves, and a cooling portion connected to a cooling line supplying a coolant; and a temperature sensor which is connected to a sensor line and is protruded outside the electrode needle through a through-hole formed at the electrode needle.
