Claim 2:
3. A surgical system comprising:
an articulatable surgical instrument comprising:
an end effector to treat tissue, wherein the end effector comprises an ultrasonic blade, and wherein the ultrasonic blade comprises a flange;
a hollow shaft extending proximally from the end effector along a longitudinal axis, the hollow shaft comprising a rigid portion and a flexible portion at a first position on the longitudinal axis distal from the rigid portion;
a waveguide extending through the hollow shaft and acoustically coupled to the ultrasonic blade, wherein the waveguide comprises 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; and
an interface portion positioned within the hollow shaft, wherein the interface portion is configured to translate within the hollow shaft between a proximal position and a distal position in response to a user input, wherein the interface portion causes the flange to cause the ultrasonic blade to pivot about the longitudinal axis as the interface portion translates between the proximal position and the distal position, and wherein the interface portion comprises a wedge configured to engage the flange as it translates between the proximal position and the distal position; and

an instrument mounting portion coupled to the end effector, wherein the instrument mounting portion is configured to pivot the end effector.
