摘要：
Electrosurgical instrument (10) with a proximal end and a distal end, comprising: - an arrangement (14) of jaw pieces at the distal end, which has a first jaw piece (18), as well as a second piece (20 ) of jaw that can move with respect to this, in which the jaw pieces (18, 20) can move relative to each other from an open position to a grip position, grip position in which they are arranged closer each other than in the opening position, each jaw piece (18, 20) has at least one electrode (32, 33, 36, 37) that can be connected to an electric power source, and electrodes (32, 33, 36, 37) of the two jaw pieces (18, 20) may cooperate to seal body tissue held in the grip position between the jaw pieces (18, 20)； - a drive device (12) for moving the jaw pieces (18, 20) from the opening position to the gripping position, and - a device (50) for limiting the width of the pieces (18) , 20) of jaw, when these are moved from the opening position to the gripping position, the device (50) presenting a plurality of limiting elements (51, 52), characterized in that only two of the elements of Limitations are designed as an electrically insulating spacer member (53, 54), which protrudes from the jaw piece (18, 20) in the direction of the other jaw piece (20, 18) by a sealing surface configured by the at least one electrode (32, 33, 36, 37) of the jaw piece (18, 20), the two spacer members (53, 54) being arranged in different jaw pieces (18, 20), and at least one member spacer (53, 54) in a distal terminal zone of the arrangement (14) of pi Jaw ages.Instrumento electroquirúrgico (10) con un extremo proximal y un extremo distal, que comprende: - una disposición (14) de piezas de mordaza en el extremo distal, que presenta una primera pieza (18) de mordaza, así como una segunda pieza (20) de mordaza que puede moverse con respecto a esta, en la que las piezas (18, 20) de mordaza pueden trasladarse una respecto a otra desde una posición de apertura hasta una posición de agarre, posición
