Abstract
An electrosurgical instrument configured for connection to a supply apparatus for operation. The instrument has an end opening at the distal end and supports at least one electrode in the area of the end opening to which an alternating voltage potential can be applied. Directly adjoining the end opening, a liner of the electrosurgical instrument limits a flow chamber inside the liner. With distance to the end opening a flushing channel opens out into the flow chamber via an exit opening and a suction channel opens out into the flow chamber via an inlet opening. A flushing fluid can be introduced in the flow chamber via the flushing channel and can be extracted by suction via the suction channel.
