A surgical stapling and severing instrument particularly suited to endoscopic use includes a proximal portion that is manipulated external to a patient to position an attached elongate shaft and end effector to a desired surgical site inside of the patient. 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.
