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 firing bar translates within the elongate shaft and articulates through the articulation joint with a reduced force to fire, supported within a knife slot formed in a link that pivots at both ends, thereby reducing the radius of curvature of the firing bar by half at a particular location. One version includes a link that connects across portions of a closure sleeve assembly and another version includes a link that connects proximal and frame ground portions.
