Claim 16:
17. A surgical instrument, comprising:
(a) an ultrasonic transducer;
(b) a body portion extending along a longitudinal axis and configured to receive the ultrasonic transducer along the longitudinal axis such that the ultrasonic transducer is rotatable about the longitudinal axis; and
(c) an electrical coupling assembly configured to electrically connect a power supply of an electrical power to the ultrasonic transducer, the electrical coupling assembly including:
(i) a first electrical connection configured to electrically connect to the power supply,
(ii) a second electrical connection electrically connected to the ultrasonic transducer,
(iii) a first plurality of conductive members secured between the first and second electrical connections, wherein the first plurality of conductive members electrically connect the first and second electrical connections such that the ultrasonic transducer is configured to receive the electrical power from the power supply while rotating the ultrasonic transducer relative to the body portion about the longitudinal axis,
(iv) a biasing element configured to urge at least one of the first plurality of conductive members into securement between the first and second electrical connections, and
(v) a first annular trough about the longitudinal axis, wherein the biasing element is positioned against the body portion and urges the at least one of the first plurality of conductive members into the first annular trough.
