1. A surgical instrument comprising:
a pivoting portion;
a shaft disposed in the pivoting portion;
a first drive motor disposed in the pivoting portion and being configured to rotate the shaft; and
a second drive motor disposed in the pivoting portion and being configured to linearly translate the shaft and wherein the second drive motor includes a rotor and a drive gear each defining an aperture extending therethrough to receive the shaft and to enable the shaft to freely rotate and linearly translate therethrough; and
wherein said drive gear is configured to cooperate with a driven gear that is fixed to one end of each of a plurality of leadscrews which enable linear translation of the shaft relative to the hand-held portion.
