Irrigated ultrasonic device with features for dissecting dense tissue

Abstract

Systems and methods whereby a surgical instrument includes an ultrasonic transducer contained in a housing and a transmission assembly at least partially received by the housing. The transmission assembly enabled to encapsulate a waveguide, wherein the waveguide transmits ultrasonic vibrations from the transducer to the ultrasonic blade. The ultrasonic blade includes a blade tip and at least one incorporated feature between a distal end of the ultrasonic blade and a proximal end, wherein the at least one incorporated feature includes one or more depressions or protrusions, creating abrasive surfaces and channels. The abrasive surfaces capable of breaking up tissue and the channels capable of collecting and expelling the broken-up tissue. A control switch operable to initiate and halt the ultrasonic transducer.
