A reusable endoscopic surgical instrument includes a handle assembly attached to a slender shaft assembly. The shaft assembly includes inner and outer shafts, with the inner shaft being rotatable by operation of the handle assembly to rotate a surgical tool operably connected to the distal end of a pushrod disposed within the inner shaft. The handle assembly includes first actuating mechanism for actuating the pushrod to operate the surgical tool and a second actuating mechanism for rotating the inner shaft. The outer shaft is axially slidable with respect to the inner shaft to cover a flush port system in the handle assembly for cleaning and improved sterilizability of the instrument.
