Abstract: The invention herein provides an integrated drape for use in surgical procedures involving anatomical extremities and having a unitary assembled structure, said drape comprising: a flexible panel sheet portion having first and second opposing sides and having a fenestration located therethrough; and a flexible elongate sleeve portion having an open proximal end; wherein the open proximal end of said sleeve is integrally attached to the panel sheet and circumscribes the fenestration. The drape readily accommodates various anatomical extremities, permits the creation of a surgical access site at any location for a given extremity, and is presented to the user as a single, one-piece construction reducing or eliminating the need for obtaining and setting up supplemental drapes for a procedure.

Abstract: A surgical cutting instrument for cutting body tissue has an axially elongated support shaft which supports, at a distal end thereof, a back biting assembly. The back biting assembly has a ring-shaped jaw member pivotally supported by the support shaft at a distal end thereof for rearward pivotal movement toward and away from a closed cutting position. A fixed cutting block member, supported by the support shaft at a position proximally of the pivot axis of the ring-shaped member is aligned with and cuttingly engages the ring-shaped member to cut or punch any tissue within the opening of the pivotal jaw member. The fixed cutter member can have a serrated, parallel rib surface facing the moveable jaw member, with at least one serration being taller than the others for blocking the entry of tissue or other foreign objects into the space wherein the pivotable member rotates thereby to prevent blocking of that rotation by such foreign objects.
