Abstract

An electrosurgical instrument includes a proximal end and a distal end having a jaw member assembly at the distal end including a first jaw member and a second jaw member movable relative thereto. The jaw members can be transferred relative to each other from an opening position into a gripping position in which they are arranged to be closer to each other than in the opening position. Each jaw member has at least one electrode connectable to an electric power source and electrodes of both jaw members being adapted to interact for sealing body tissue held between the jaw members in the gripping position, actuating means for transferring the jaw members from the opening position into the gripping position and means for limiting the closing width of the jaw members, when they are transferred from the opening position into the gripping position.
