Principle Electro surgery is the application of a high-frequency electric current to biological tissue as a means to cut, coagulate, desiccate, or fulgurate tissue. Electrosurgical devices are frequently used during surgical operations helping to prevent blood loss in hospital operating rooms or in out patient procedures.

MODES The device has several modes: Cut modePure sine wave, for cutting with the least coagulation. Coag modePulsed sine wave, low-duty cycle, for coagulating bleeding tissue. Blend 1 modeModulated sine wave, for coagulating as the tissue is cut. Blend 2 modeModulated sine wave, for coagulating as the tissue is cut.

Staff safety Avoid contact with the neutral electrode When applying current, always be sure to wear gloves and touch the equipment or patient body with the entire palm of the hand, not with a single finger. Electrosurgical equipment needs to be grounded in order to minimize interference with video endoscopic systems. Smoke generated during electrosurgical procedures can be irritating and potentially harmful to personnel; surgical masks and adequate ventilation of smoke may be useful
Advantages over other techniques The laser is less efficient, less powerful, more costly, more bulky in the operating room and less understood due to a smaller case history data base work to discourage its use in many cases. So much depends upon the skill of the surgeon in the use of any surgical knife, that the selection is often a professional judgment.
Thank you !!!
