Claim 17:
18. A method of using an ultrasonic surgical instrument including a shaft assembly having a dynamic tube and a static tube, an end effector having an ultrasonic blade and a clamp arm, and a base, the method comprising:
(a) translating the shaft assembly relative to the base, wherein the act of translating the shaft assembly relative to the base includes rotating a spool to pay in one of a proximal insertion cable or a distal insertion cable and to pay out the other of the proximal or distal insertion cables; and
(b) actuating the clamp arm relative to the ultrasonic blade, wherein the act of actuating the clamp arm relative to the ultrasonic blade includes manipulating at least one closure pulley to cause a change of length of a closure cable within the base to thereby translate the dynamic tube relative to the static tube.
