Mono vs Bipolar Cautery
Mono vs Bipolar Cautery Cautery may be a therapeutic method utilized to evacuate or crush undesirable tissue or control bleeding by applying heat to the affected area. The initial incision is made by a scalpel. The Electrosurgical unit (ESU) is not used to incise the skin. Electrosurgery can be used on fat, fascia, muscle, internal organs, and vessels. ESUs operate at frequencies between 100,000 and 1 0,000,000 Hz. This current can be passed through tissue without causing stimulation of muscles or nerves. Electrosurgery differs from electrocautery. Electrocautery is the use of a unidirectional current generated by a self-contained battery-operated disposable instrument with a wire at the tip. The wire heats when activated and coagulates the tissue. The energy does not enter the patient’s body. The ESU uses an alternating current that passes through the patient’s tissues and returns to the generator. Two forms of cautery are commonly used in surgery: ...
