1. A multi-functional surgical instrument, comprising:
an elongate shaft extending between a proximal end and a distal end;
a wrist extending from the distal end of the elongate shaft, wherein the wrist includes a distal clevis having a first curved surface, wherein the first curved surface defines at least one pivot axis;
an end effector extending from the pivot axis of the wrist, the end effector comprising a first jaw and a second jaw, the first and second jaw being moveable between an open position in which ends of the first and second jaws are separated from each other and a closed position in which the ends of the first and second jaws are closer to each other as compared to the open position, wherein the end effector further includes a first outer pin and a first inner pin, wherein the first outer pin receives the first inner pin therein to movably connect the first and second jaws together, and wherein the first outer pin is received against the first curved surface such that the end effector is configured to pivot about the at least one pivot axis; and
a tube extending through the elongate shaft and the wrist, the tube having an outlet in fluid communication with a nozzle cooperatively formed by an interior surface of the first and second jaws when the first and second jaws are in the closed position, wherein each of the first and second jaws are movable relative to the tube.
