Claim 4:
5. An articulatable surgical instrument comprising:
an end effector comprising an ultrasonic blade, wherein the ultrasonic blade comprises a flange;
a hollow shaft extending from the end effector along a longitudinal axis, the hollow shaft comprising a rigid shaft portion and a flexible shaft portion;
a waveguide extending through the hollow shaft and acoustically coupled to the ultrasonic blade, the waveguide comprising a flexible waveguide portion; 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, wherein the flexible waveguide portion is positionally aligned with the flexible shaft portion such that the end effector is pivotable away from the longitudinal axis, and wherein the interface portion comprises a wedge configured to engage the flange as it translates between the proximal position and the distal position.
