Abstract: A surgical device can include a first jaw, a second jaw opposing the first jaw, a clamp lever in communication with the first jaw and the second jaw and operable to move the first jaw, the second jaw, or both from a jaw nominal position to a 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.

Abstract: A forceps includes jaws, a first shaft having a first slot, a second shaft extending along the first shaft and having a second slot, and a rod that extends along the second shaft. The rod has a third slot including a locking portion and a guide track portion.
