1. An end effector for an electrosurgical instrument, comprising:

  • a first jaw comprising a first energy delivery surface, a first distal end, and a first proximal end;

    a second jaw comprising a second energy delivery surface, a second distal end, and a second proximal end, wherein the first and second jaws are pivotally coupled at the first and second proximal ends, such that at least one of the first and second jaws is configured for movement between a closed position where the first and second distal ends are in proximity and the first and second energy delivery surfaces face each other, and an open position where the first and second distal ends are spaced apart;

    an electrically conductive member protruding from the second jaw, wherein the electrically conductive member is in proximity to the second distal end; and

    a pivot in proximity to the first and second proximal ends, wherein the electrically conductive member and the pivot cooperate to maintain a gap between the first energy delivery surface and the second energy delivery surface in the closed position, wherein the electrically conductive member is in contact with the first jaw in the closed position, wherein the pivot is fixed in position to finalize a distal gap distance between the first and second energy delivery surfaces in proximity to the first and second distal ends and a proximal gap distance between the first and second energy delivery surfaces in proximity to the first and second proximal ends, and wherein the distal gap distance is different from the proximal gap distance.
