摘要：
A surgical stapling instrument comprises a cartridge device with a row of staples and a wavy first tissue interface, and an anvil having a wavy second tissue interface which cooperates with the first tissue interface for clamping tissue therebetween and forming the staples exiting from the cartridge device, a staple driving device adapted to drive the staples out of the cartridge device towards the anvil, wherein the staples are non-symmetrical U-shaped with two legs protruding toward the anvil and a transverse basis connecting the legs, wherein the basis is inclined with respect to the longitudinal direction of the legs and has a length greater than the staple projection on a plane perpendicular to the longitudinal direction of the legs.
