1. A surgical instrument comprising:
(a) an ultrasonic transducer assembly rotatably mounted along a longitudinal axis and defining a first outer profile that is transverse to the longitudinal axis; and
(b) a transducer slip joint proximally positioned relative to the ultrasonic transducer assembly and configured to electrically connect a power cord with the ultrasonic transducer assembly such that the ultrasonic transducer assembly is configured to rotate about the longitudinal axis relative to the power cord while the power cord provides power to the ultrasonic transducer assembly, wherein the transducer slip joint defines a second outer profile that is transverse to the longitudinal axis, and wherein the second outer profile fits within the first outer profile of the ultrasonic transducer assembly in a distal direction, wherein the transducer slip joint includes:
(i) an electrical cord contact configured to electrically connect to the power cord, and
(ii) a dynamic body rotatably coupled with the ultrasonic transducer assembly and having an electrical transducer contact electrically connected to the ultrasonic transducer assembly, wherein the electrical transducer contact is positioned distally from the electrical cord contact relative to the longitudinal axis and slidingly receives the electrical cord contact longitudinally thereagainst such that the electrical transducer contact and the electrical cord contact are configured to communicate electrical power therebetween.
