Claim 10:
11. An ultrasonic surgical instrument, comprising:
(a) an end effector including an ultrasonic blade;
(b) a shaft assembly defining a longitudinal axis and proximally extending from the end effector, wherein the shaft assembly includes an acoustic waveguide in acoustic communication with the ultrasonic blade;
(c) an ultrasonic transducer assembly proximally extending from and in acoustic communication with the acoustic waveguide;
(d) a housing proximally projecting from the shaft assembly such that the ultrasonic transducer assembly is positioned within the housing;
(e) a carrier movably supporting the ultrasonic transducer assembly along the longitudinal axis such that the ultrasonic transducer assembly, the acoustic waveguide, and the end effector are configured to collectively move relative to the housing from a proximal, retracted position on the longitudinal axis to a distal, extended position on the longitudinal axis for inserting the ultrasonic blade into a patient;
(f) an electrical cable extending through the housing at a cable port and electrically connected to the ultrasonic transducer assembly, wherein the electrical cable is configured to transmit electrical communication therealong for operating the ultrasonic transducer assembly; and
(g) a cable guide positioned in the housing and extending between the cable port and the ultrasonic transducer assembly, wherein the cable guide defines a predetermined path and receives the electrical cable along the predetermined path such that the cable guide is configured to retain the electrical cable along the predetermined path as the ultrasonic transducer assembly selectively moves from the proximal, retracted position to the distal, extended position,
wherein the cable guide includes a plurality of links pivotally connected in succession to define the predetermined path.
