Glossary of Terms Bipolar Electrosurgery Electrosurgery in which current flows between two bipolar electrodes that are positioned around tissue to create a surgical effect (heating, desiccation). Electrical current passes from one electrode through the desired tissue to the second electrode, thus completing the electrical circuit without dispersing through other parts of the patient’s body. Bipolar instrument An electrosurgical instrument or accessory that incorporates both an active and return electrode. Electrosurgery The directed passage of high frequency electrical current through tissue from an electrode that concentrates the electrical current to a larger electrode (return electrode) that disperses and returns the current to a power supply (RF generator) in order to produce a surgical effect (tissue cutting, tissue coagulation). Error Condition that requires mitigation by user actions. Fault Condition that requires power cycling or factory maintenance. RF Generator The power supply that converts low frequency alternating current to high frequency current used for electrosurgery. Hemostasis The stopping of bleeding from blood vessels, either spontaneously (with no intervention) or with mechanical and/or electrosurgical instruments and/or pharmaceutical agents. Instrument The sterile, single use electrosurgical device that, when connected to the RF generator, delivers radiofrequency energy (RF). Instrument Cable The cord which connects the electrosurgical instrument to the RF generator and delivers radiofrequency energy (RF). Regrasp Indicator An audible series of tones that indicate the potentially inadequate sealing of the tissue within the instrument jaws (see Regrasp Caution under section 7.5.) Radio Frequency Frequencies below 550kHz that transmit radio signals; radiofrequency energy (RF) is the high frequency current used in electrosurgery.
