摘要
A monopolar electrosurgical instrument and electrosurgical system for treating biological tissue by a plasma. The instrument includes a tubular line for conducting a gas to the treatment location, wherein the line consists of electrically insulating material and has a distal opening for the exit of the gas in the direction of the tissue to be treated, and an electrode arranged in the region of the distal opening in the line, wherein the electrode is connectable to an electrosurgical generator to ignite a plasma discharge in the gas. Improving the ignition behavior, the inner surface of the line has an enhanced electrical conductivity in the distal opening. Furthermore, a method for producing an electrosurgical instrument for providing a line made of nonconductive material, an electrode, and enhancing the conductivity of an inner surface of the line in the region of the opening, for enhancing the conductivity in the line.
