1. A surgical device comprising:
a first jaw;
a second jaw opposing the first jaw, the first jaw, the second jaw, or both being movable relative to one another between a jaw nominal position and a jaw clamped position;
a clamp lever operable for moving the first jaw, the second jaw, or both from the jaw nominal position to the jaw clamped position when an external force is imparted upon the clamp lever in a first direction; and
a stop bias member that stops movement of the clamp lever when the external force is removed so that the first jaw and the second jaw are in the jaw nominal position at rest, and
a return bias member, wherein the return bias member provides a force in a first direction and the stop bias member provides a force in a second direction that opposes the return bias member force so that a net force is zero.
