Abstract
A surgical tool assembly that includes an elongate shaft that has an end effector coupled thereto for selective articulation relative to the shaft. A first articulation link operably interfaces with a source of articulation motions configured to selectively axially move the first articulation link a first axial distance in a first articulation direction. A second articulation link operably interfaces with the surgical end effector to apply articulation motions thereto. An articulation stroke multiplier operably interfaces with the first articulation link and the second articulation link such that when the first articulation link is axially moved the first axial distance in the first axial direction, the articulation stroke multiplier moves the second articulation link another first axial distance in the first axial direction that is greater than the first axial distance.
