Monopolar electrosurgery provides hemostasis for vessels smaller than 2 mm in diameter, and collateral damage can occur up to 2 cm from the coagulation site [6, 7].
A multitude of electrodes are available for the electrosurgical pencil, with three basic shapes: Needle tip, spatula, and J‐hooks. The use of insulated electrode extensions has become popular for endoscopic surgery. These extensions enable the use of the standard electrosurgical pencil in endoscopic surgery (ssss1). An L‐ or J‐hook electrode is also very commonly used during minimally invasive surgery (MIS) for dissection. These electrodes allow dissection of tissue by hooking in the tip while the ESU is activated. This technique is used frequently during cholecystectomy. With the advent of the TriVerse handpiece (Valley Lab, Boulder, CO), the surgeon can adjust the power level with the handpiece rather than relying on an assistant to adjust the power at the generator (ssss1). Monopolar electrodes are available in a device that also allows for irrigation and suction at the surgical site. With the irrigation and suction present, the surgical field can be kept clean, and more precise and efficient dissection can be performed with the monopolar cautery tip. An insulated endoscopic instrument can be connected to an ESU and used as a monopolar electrosurgery device. Endoscopic grasping forceps may then be used to provide hemostasis. Insulated endoscopic scissors can also be used. A foot pedal is used to activate the electrocautery unit when the scissors are cutting tissue. Hand‐activated switches are also available.
