US 2025/0017585 A1 · SURGICAL STAPLER END EFFECTOR SLED HAVING CARTRIDGE WALL SUPPORT FEATURE

Abstract

A staple driver actuator for a surgical stapler includes a base having at least one bottom surface. The bottom surface defines a plane and is configured to slide longitudinally relative to a jaw of the surgical stapler. The staple driver actuator also includes a plurality of rails extending upwardly from the base. Each of the plurality of rails includes at least one cam surface, and each of the cam surfaces is inclined relative to the plane. The plurality of rails includes a laterally-opposed pair of outer rails and a laterally-opposed pair of inner rails. The staple driver actuator further includes a distal nose extending distally from at least a portion of the base and having at least one ledge surface. The ledge surface faces upwardly, is parallel to the plane, and is at least partially positioned distally relative to each of the outer and inner rails.
