Surgical instruments for ultrasonic tissue emulsification and ultrasonic shearing

摘要

The instrument includes an ultrasonic blade, a first fluid port in communication with the distal opening of the ultrasonic blade, a clamp arm, an irrigation member positioned adjacent to the distal end of the ultrasonic blade, and an irrigation member And a second fluid port in communication. The ultrasonic blade defines a distal opening. The ultrasound blade is operable in a first mode for emulsifying tissue positioned distal to the ultrasound blade. The ultrasonic blade is further operable in a second mode for transecting and sealing tissue positioned transverse to the ultrasonic blade. The clamp arm is pivotable towards and away from the ultrasonic blade.
