Abstract
A surgical device for operating on tissue comprises an end effector, a disposable shaft assembly, and an interface assembly. The shaft assembly comprises an articulation section operable to provide deflection of the end effector relative to the longitudinal axis of the shaft. The interface assembly comprises a plurality of pivotable base sections. The interface assembly comprises a plurality of drive components associated with drive shafts driven by an external system and each drive component is associated with a section of the base. The drive components are operable to cause rotation of one or both of the shaft or end effector and movement of components of the end effector. The drive components are further operable to cause articulation of the articulation section. The base sections are pivotable toward each other to couple with the shaft assembly or away from each other to disengage the shaft assembly.
