## Indications for use
The Force Argon™ II Argon Enhanced Electrosurgical System is intended for use in both open, laparoscopic, and thoracoscopic surgical procedures (general, neurosurgical, gynecologic) where monopolar electrosurgery (cutting and coagulation) is normally used. The Force Argon™ II Argon Enhanced Electrosurgical System provides a controlled flow of argon to electrosurgical handsets during cutting and coagulation. When the handset is activated in the gas enhanced modes, an argon gas plasma is created between the electrode and the tissue.
