摘要:
A surgical fastener applying apparatus, comprising: an anvil member having a tissue contacting surface a cartridge member extending along a longitudinal axis and being movably coupled to the anvil member, the cartridge member including a plurality of surgical fasteners and a plurality of pushers operatively associated with the plurality of surgical fasteners, each pusher including a base portion and a plurality of pusher plates extending from the base portion such that adjacent pusher plates define an acute angle therebetween and a sled operably engagable with the plurality of pushers, wherein engagement of the sled with the pushers urges the surgical fasteners toward the anvil member such that a first row of surgical fasteners applies a first compressive force to tissue disposed between the anvil member and the cartridge member, and a second row of surgical fasteners applies a second, different compressive force to tissue disposed between the anvil member and the cartridge member, wherein each pusher plate extends from the base portion to define a different length such that the compressive forces are varied along an axis transverse to the longitudinal axis of the cartridge member.
