An electrosurgical system is disclosed, including an electrosurgical generator and an electrosurgical instrument which is or can be connected to the electrosurgical generator, wherein the electrosurgical instrument comprises at least a first activation element and a second activation element and the electrosurgical generator is configured to, on actuation of the first activation element, deliver an electrosurgical therapy signal having a first signal shape to the electrosurgical instrument, and, on actuation of the second activation element, deliver an electrosurgical therapy signal having a second signal shape. The system is characterized in that the first signal shape and the second signal shape are identical, and in that the electrosurgical generator is further configured to only perform success monitoring of a tissue effect achieved by the electrosurgical therapy signal on actuation of the first activation element.

Electrosurgical system, electrosurgical generator and electrosurgical instrument

An electrosurgical generator supplies, during operation, a high-frequency alternating current to an electrosurgical instrument for plasma cutting of body tissue. The electrosurgical generator has outputs for connecting an electrosurgical instrument to supply an electrosurgical instrument connected to the outputs with a high-frequency alternating current, and for determining the impedance of a load connected to the outputs. The electrosurgical generator features impedance and voltage measuring units as well as an output voltage control unit. The output voltage control unit is designed to control the AC output voltage depending on a maximum output voltage value that is set during operation depending on an output value of the impedance measuring unit and/or depending on an output value of the voltage measuring unit, such that the maximum output voltage value predefines a lower AC output voltage during a vaporization phase than during an ignition phase occurring subsequently to the vaporization phase.
