Abstract

An articulation assembly for a surgical instrument, surgical instrument including the same, and robotic surgical system including a surgical robot and the surgical instrument including the articulation assembly. The articulation assembly includes lead screw assemblies each including a lead screw and a collar operably engaged about the lead screw such that rotation of the lead screw translates the collar about the lead screw. Articulation cables are operably coupled to the collars of the lead screw assemblies such that proximal movement of one of the collars about the respective lead screw tensions the corresponding articulation cable and such that distal movement of one of the collars about the respective lead screw de-tensions the corresponding articulation cable. Proximal gear assemblies are coupled to the lead screws. Coupling gears couple pairs of the proximal gear assemblies with one another to maintain a pretension on the corresponding articulation cables.
