摘要：
The invention relates to an electrosurgical instrument with a proximal end and a distal end, comprising a jaw part arrangement at the distal end which has a first jaw part and a second jaw part movable relative thereto, wherein the jaw parts are transferable relative to one another from an opening position into a gripping position, in which they are closer to one another than in the opening position. Each jaw part has at least one electrode that can be connected to an electrical energy source and electrodes of the two jaw parts can cooperate with one another to seal body tissue held between the jaw parts in the gripping position. The electrosurgical instrument further comprises an actuating device for transferring the jaw parts from the opening position to the gripping position, and a device for limiting the closing width of the jaw parts when they are transferred from the opening position to the gripping position. Said device comprises a plurality of limiting elements, a maximum of two limiting elements being arranged on one jaw part. Said limiting elements are designed as electrically insulating spacer members projecting from the jaw part in the direction of the other jaw part over a sealing surface formed by the at least one electrode of the jaw part, at least one spacer member being arranged at the distal end of the jaw part arrangement.
