摘要：
abstract a surgical stapler includes and end effector configured to receive an upper staple cartridge and a lower staple cartridge. the lower staple cartridge includes staple drivers disposed at a non-perpendicular or oblique angle. the staple drivers may be oppositely angled relative to the perpendicular. the staple drivers may further be coupled to an actuation member that pivots the staple drivers to the perpendicular prior to stapling. the acting members may be performed by the firing bar and / or by a wedge sled. the upper staple cartridge may also include angled staple drivers that are pivotable to the perpendicular. the upper staple cartridge and / or the lower staple cartridge may also include staple forming pockets. alternatively, one staple driver may be perpendicular and second staple driver may be at a non-perpendicular angle. the second driver may be actuated into an angled stamped recess. "double staple cartridge for surgical stapler" The present invention relates to a surgical stapler (10) including an end actuator (12) configured to receive an upper staple cartridge (160) and an upper staple cartridge (120). the lower staple cartridge includes staple drivers (43) arranged at a non-perpendicular or oblique angle. the clamp actuators may be at an opposite angle to the perpendicular. the clamp actuators may further be coupled to an actuation element that pivots the clamp actuators to the perpendicular prior to stapling. the actuation elements may be actuated by the firing bar (14) and / or by a wedge-shaped sliding support (41). The upper staple cartridge may also include angled staple drivers that are pivotal to the perpendicular. the upper staple cartridge and / or the lower staple cartridge may also include staple pockets (53). alternatively, a clip driver may be perpendicular and the second clip driver may be at a non-perpendicular angle. The second clamp driver may be actuated in an angled stamped recess (230).abstract a surgical stapler includes a
