1.4 – Physical principle and fundamentals of equipment technology applied to its
operation and action
Electrosurgery consists of the use of radio-frequency (RF) electric current to cut tissues or coagulate. Low
frequency electric current (below 100,000 Hz) may cause neuromuscular stimulation that could electrocute
the patient or cause a sensation of shock.
There are electrosurgical units that work at frequencies of up to 4,000,000 Hz (4 MHz), but it is very difficult
to keep that high-frequency current in wires because of parasitic capacitances and inductances. Valved
electrosurgical units generally work at frequencies close to 4 MHz. Modern transistorized equipment works
at lower frequencies. SS-200E works at 480,000 Hz (480 KHz), which is a compromise solution between
such two extreme limits.
There are basically three surgical effects that can be obtained from electrosurgery: desiccation or
cauterization, electrosurgical cut and fulguration.
