1. An electrosurgical instrument comprising:
a connection device configured to connect to a supply apparatus;
a liner having a distal end opening arranged at a distal end of the liner;
at least one electrode electrically connected with the connection device that is arranged adjacent to the distal end opening or that extends beyond the distal end opening in a longitudinal direction;
a light conducting device that comprises a light inlet surface that is arranged inside the liner;
a flushing channel fluidically connected with the connection device that comprises an exit opening that opens out into a flow chamber limited by the liner and that is arranged with distance to the distal end opening in longitudinal direction, such that a flushing fluid flowing through the flushing channel flows out of the exit opening and creates a flushing fluid flow in the flow chamber from the exit opening in direction toward the distal end opening; and
a suction channel fluidically connected with the connection device that comprises an inlet opening opening out into the flow chamber and that is configured to receive at least a portion of the flushing fluid of the flushing fluid flow via the inlet opening and to discharge it from the flow chamber.
