Abstract

A surgical instrument that comprises 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 relative thereto about an articulation axis that is laterally offset from the shaft axis and extends transversely relative thereto. An end effector driver link is operably coupled to the surgical end effector and an articulation driver that is supported for longitudinal travel in distal and proximal directions upon application of articulation motions thereto. A flexible de-articulation member is coupled to the elongate shaft assembly and the surgical end effector to apply de-articulation motions to the surgical end effector.
