In laparoscopic surgery, insulated equipment must be used and checked regularly to ensure it is intact. Not insulated metallic equipment can potentially create an alternative electrical pathway, so should be kept at a safe distance from the active electrode.
Capacitive coupling can occur when alternative current is passed from an insulated instrument to a non-insulated one through a capacitor. Metallic trocars should therefore have good contact with the abdominal wall to avoid burns, and non-conducting trocars must ensure they are in good condition to avoid burns.
