Abstract

See full text

A surgical instrument for use during a surgical procedure includes an instrument body, an ultrasonic transducer assembly extending along a longitudinal axis, a power cord, and a transducer slip joint. The ultrasonic transducer assembly is rotatably mounted within the instrument body about the longitudinal axis and defines a first outer profile. The power cord projects from the instrument body to provide electrical power to the ultrasonic transducer assembly for operating an acoustic waveguide. The transducer slip joint is positioned between the power cord and the ultrasonic transducer assembly and electrically and mechanically connects the power cord to the ultrasonic transducer assembly. The ultrasonic transducer assembly selectively rotates relative to the power cord for inhibiting the power cord from winding upon rotation of the ultrasonic transducer assembly. The transducer slip joint also defines a second outer profile that fits within the first outer profile of the ultrasonic transducer assembly.
