Abstract: A surgical instrument for performing an end-to-end anastomosis of first and second luminal structures includes a housing having an actuator attached thereto and a selectively removable loading unit attached to a distal end of the housing which supports any array of surgical fasteners at a distal end thereof. The surgical fasteners are simultaneously deformable upon activation of the actuator such that a distal end of each surgical fastener secures each end of each luminal structure to complete the end-to-end anastomosis wherein the resulting eversion is exterior to the luminal structures.

Abstract: A stapling and perforating apparatus having a base with downwardly bent edges, a support plate affixed to the base and extending vertically upwardly therefrom, a stapler pivotally interconnected to and above the base, a punch interconnected to the base above the support plate, a plurality of cylindrically-shaped protuberances extending upwardly from the base a desired distance from the punch, a tray removably fastened to the base, and a generally flat lancet having hewn edges slidably received within a slot formed in the stapler. The punch is mounted on a structure fastened to the support plate. An impact button is provided on one end of the punch. A spring resiliently maintains the impact button above the structure. The protuberances are in linear alignment and are offset from the plane of the support plate. The downwardly extending edge of the base defines a receptacle box area below the base.
