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.

13. 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 the casing comprises a pair of pins extending therefrom and wherein each of the jaws comprises; an elongated portion that extends proximally from a distal tip, a contoured portion extending from the elongated portion, an angled portion extending from the contoured portion, a connection flange extending from the angled portion, a slot formed therein, wherein one of the pins extends into the slot, wherein the connection flange is operatively attached to the jaw power screw and wherein the elongated portion, the contoured portion and the angled portion are aligned in a planar configuration; 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 laws are moved relative to each other such that the jaws pivot about a pivot pin that translates in a longitudinal, axial direction of the instrument as the jaws are moved relative to each other. - View Dependent Claims (14)
