Abstract

Various embodiments are directed to articulatable surgical instruments and surgical systems comprising articulatable surgical instruments. Some embodiments comprise an end effector to comprising an ultrasonic blade. A hollow shaft may extend proximally from the end effector along a longitudinal axis. The hollow shaft may comprise a rigid portion and a flexible portion at a first position on the longitudinal axis distal from the rigid portion. A waveguide may extend through the shaft and may be acoustically coupled to the ultrasonic blade. The waveguide may comprise a flexible portion at the first position on the longitudinal axis such that the end effector is pivotable away from the longitudinal axis from the first position.
