| 摘要 |
The present invention relates to an electrode for an electrosurgical unit for the use in ablating and necrosing a living tissue by RF electric energy. The present invention provides an electrode for an electrosurgical unit, including: a hollow electrode formed in an elongated hollow tube shape, a non-insulating region of a predetermined length being formed on one side of which, an insulating region being formed on an outer surface of which other than the non-insulating region; a saline solution circulation structure that supplies pressurized saline solution for cooling a living tissue which is in contact with the hollow electrode from the outside of the living tissue to the inside of the hollow electrode, and discharges the pressurized saline solution from the inside of the hollow electrode to the outside of the living tissue; and one or more saline solution discharge holes formed in the non-insulating region of the hollow electrode to discharge some of the circulating pressurized saline solution to the living tissue which is in contact with the hollow electrode.
