    摘要： A surgical device is disclosed which includes a handle assembly, an elongated member and a disposable loading unit. The handle assembly includes a mode selection mechanism configured to alternate the surgical device between a first grasping mode of operation and a second clamping mode of operation. The handle assembly includes a rotation control member and an articulation lever. The rotation control member is configured to facilitate rotation of the elongated member with respect to the handle assembly. The articulation lever is configured to facilitate articulation of the tool assembly about an axis substantially perpendicular to the longitudinal axis of elongated member. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly configured to clamp and staple tissue in the second clamping mode of operation of the device.

    摘要： A surgical fastener applying apparatus comprising a cartridge body including a tissue contacting surface including a plurality of fastener retention slots arranged in a plurality of rows including at least an inner row and an outer row, a plurality of surgical fasteners disposed in the inner and outer rows and configured such that a plurality of fasteners disposed in the inner row have a first diameter that is less than a second diameter of a plurality of surgical fasteners disposed in the outer row, and an anvil having an inner row and an outer row of depressions for forming the fasteners. A plurality of pushers are operably associated with the plurality of surgical fasteners, the pushers configured to eject an associated surgical fastener towards the respective depression in the anvil such that upon formation of a corresponding surgical fastener, the surgical fasteners ejected from the inner row provide a greater compressive force to tissue than the surgical fasteners ejected from the outer row.
