Abstract

A surgical instrument comprising an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective pivotal travel about an articulation axis that extends transversely relative to the shaft axis. An articulation driver is supported for selective longitudinal travel relative to the elongate shaft assembly. A central articulation link is pivotally coupled to the elongate shaft assembly for pivotal travel relative thereto. An intermediate link is movably coupled to the articulation driver and the central articulation link. An end effector driver is movably coupled to the central articulation link and the surgical end effector.
