electrocautery
The use of electrical current to cut tissue or achieve hemostasis during laparoscopic surgery.
Full Definition
Electrocautery in laparoscopic surgery involves the application of high-frequency electrical current through specialized instruments to cut tissue (cutting mode) or coagulate bleeding vessels (coagulation mode). Modern electrosurgical units offer various waveforms and power settings. Bipolar electrocautery confines current between two electrode tips, making it safer near vital structures, while monopolar electrocautery uses a dispersive pad. Proper grounding and careful technique are essential to prevent thermal injury to adjacent organs, particularly in the confined space of laparoscopic surgery.
Usage
Usage note: Specify bipolar vs. monopolar when documenting procedures.
