PROBLEM TO BE SOLVED: To provide an electric surgical device in which plasma gas can be directly applied to an affected part inside a living body without cutting the surface of the living body. SOLUTION: A plasma jetting catheter device comprises a high frequency high voltage AC power source part 54, an electrode 56a, a gas supply source 58, a casing 68, and a catheter 78, where the high frequency high voltage AC power source part 54 is connected to the electrode 56a. The electrode 56a is fixed inside the casing 68 in an insulated condition, and the casing 68 is connected to the gas supply source 58 and the catheter 78 to be communicated with them, thereby gas plasma generated close to the electrode 56a is jetted from the catheter 78. |
