Dr.Wheeler's patient,a 72-year-old man with a single early-stage liver tumor,has an implanted automatic internal defibrillator that the anesthesia provider has decided not to disarm for the procedure.What energy-generated dissection device should Dr.Wheeler use to replace the argon beam coagulator?

Question

Vibrating energy devices provide a safe option for cutting and coagulation.High-frequency sound waves are propagated to a blade tip to produce ultrasonic energy.The following are advantages of using an ultrasonic device to cut and coagulate:No surgical plume or odor is generated;only a small amount of aerosolization is created.Less adjacent tissue is damaged compared with laser and ESU devices.Tactile feedback is retained.No nerve or muscle stimulation occurs because no electrical current is delivered to the target area.No stray electrical or laser energy is produced.Precise cutting and control are offered.
