An electrosurgical unit is a device that uses high-frequency (HF) electrical currents to cut or coagulate tissue during surgery, known as electrosurgery. It consists of an electrosurgical generator that transforms electrical energy into HF current. It is operated using a specific control. The generator is connected to an active electrode. It is this active electrode that comes into contact with the tissue it will create a thermal effect on. Electrosurgical units have multiple functions and electrodes that vary according to the surgical applications.
What are the different types of electrosurgical units?
There are different types of surgical units that use different sources of energy: radio frequency or high-frequency, ultrasound and molecular resonance.
Radio frequency (or high-frequency) surgical units: these are the most common type of surgical units on the market. They transform mains current into HF current (> 200 kHZ).
Ultrasound surgical unit: these units work with ultrasonic handpieces. They have an ultrasonic wave generator. These ultrasound waves break the hydrogen bonds of the cells during coagulation, while the cutting is done by cavitation.
Molecular resonance surgical unit: unlike high frequency surgical units, these units use frequencies that interact with tissue in a non-thermal way. Tissue is only modified on a molecular level, making this technique is less invasive.
