Energy Systems - Common Surgical Instruments Broad term used to describe various methods of cutting tissue or sealing vessels. May use electricity or sonic waves. Available in open or laparoscopic forms. • Electrosurgery: Instrument that cuts or cauterizes tissue via an alternating electrical current. Open (shown) and laparoscopic (Ligasure®) applications. • Ultrasonic: (Harmonic®) uses highfrequency sound to concurrently cut and seal tissue. Less thermal spread than electrosurgery, but more time consuming. • Endostapler: Used in laparoscopic procedures, provides simultaneous cutting and stapling. May be manual or electronic. Some feature articulating heads to accomplish more difficult placement. - Dr. Michael Visenio @BigMike_MD #Energy #Systems #surgery #instruments #types #comparison
