1. An endoscopic forceps, comprising;

  • an elongate shaft including a distal end and a proximal end, the elongate shaft defining an instrument axis;

    an end effector adjacent the distal end of the elongate shaft, the end effector including first and second jaw members each supporting a corresponding sealing surface thereon for clamping tissue therebetween, at least one of the jaw members movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue;

    a cutting instrument including a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members, wherein the reciprocating blade contacts an undersurface of an opposite jaw member when the jaw members are in the closed configuration to define a gap distance between the sealing surfaces;

    a handle adjacent the proximal end of the elongate shaft, the handle operable to induce motion in the jaw members to move the jaw members between the first configuration and second configuration; and

    an actuator operable to selectively translate the reciprocating blade.
