1. An instrument for use in a medical procedure, the instrument comprising:
a proximal end; a distal end; a handle adjacent to the proximal end of the instrument; a flexible elongated neck extending distally from a distal end of the handle; a jaw power screw extending from a distal end of the neck; a pair of moveable jaws operatively connected to the jaw power screw utilizing a casing, wherein each of the jaws comprise a slot formed therein, wherein the casing comprises a pair of pins extending therefrom and wherein one of the pins extends into each of the slots; and a handle power screw assembly operatively connected to a proximal end of the flexible neck within the handle; wherein manipulation of the handle controls movement of the jaws relative to each other; and wherein the pins are slidable in the slots as the jaws are moved so that the jaws are moveable toward and away from each other while simultaneously translating in a longitudinal, axial direction relative to the distal end of the instrument such that the jaws pivot about a pivot pin that translates in the longitudinal, axial direction as the jaws are moved toward and away from each other.
