Abstract
An energy based surgical device for the application of ultrasonic energy and Radio Frequency energy is disclosed. The surgical device has a housing and an acoustic assembly having an electrically conductive waveguide. The waveguide has a solid core and extends from the housing. A conductive element for conducting Radio Frequency energy to the waveguide is operably coupled to the waveguide. The distal end of the waveguide of the acoustic assembly has an end effector for the conduction of ultrasonic energy or Radio Frequency energy. A number of novel end effectors for the emulsification and cauterization of tissue are described.
