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.
