An articulation joint pivotally attaches the end effector to the elongate shaft to give further clinical flexibility in reaching tissue at a desired angle. A closure tube assembly includes a single pivoting portion that overrides the articulation joint in order to distally translate to the end effector to close, yet pass over an articulated shaft by having a multiple pivot frame ground encompassed therein to accommodate the longitudinal change in closure sleeve pivot. Thereby, additional clinical flexibility in positioning the end effector is achieved without losing the ability for separate closure and firing motions transferred by the shaft.
