An endoscopic surgical instrument for performing a surgical procedure inside a patient, said instrument comprising:

• a handle assembly including a grip for holding the instrument and a plurality of controls for controlling movement of the instrument;
• an elongate shaft having a grip end mounted on the handle assembly and a working end opposite said grip end, said shaft having a proximal portion adjacent said grip end and a distal portion adjacent said working end, said proximal portion having a centerline and being selectively rotatable with respect to the handle assembly about the centerline of the proximal portion of the shaft, said distal portion having a centerline and being selectively articulatable relative to the centerline of the proximal portion of the shaft;
• and
• an end effector mounted on the working end of the elongate shaft, said end effector being selectively rotatable about the centerline of the distal portion of the shaft.
