    摘要: A surgical device is disclosed which includes a handle portion, a central body portion and a single use loading unit, or “SULU”. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.

    摘要: A staple drive assembly includes an actuation sled and at least one staple pusher. The staple drive assembly is adapted to fit within a staple cartridge having a plurality of staples and a corresponding number of retention slots. The at least one staple pusher includes at least one pusher plate for releasably engaging a backspan of a staple. The staple pusher may include a plurality of pusher plates that may be laterally and longitudinally spaced apart. An actuation member has at least one angled camming surface for engaging a complimentary angled surface of the at least one staple pusher. Camming engagement between the actuation member and the at least one staple pusher causes vertical movement of the at least one staple pusher. Lateral and longitudinal offset of the actuation member camming surfaces and the corresponding staple pusher following surfaces improves stability and control of the staple pusher during firing.
