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 proximal gear assemblies arranged in diagonally-opposed pairs and distal gear assemblies coupled to the respective proximal gear assemblies and likewise arranged in diagonally-opposed pairs. Each distal gear assembly defines an opposite configuration as its diagonally-opposed distal gear assembly. First and second coupling gears couple the diagonally-opposed pairs of proximal gear assemblies such that an input to one of the proximal gear assemblies of a diagonally-opposed pair provides opposite outputs of the corresponding distal gear assemblies.
