DEFINITION OF ELECTROSURGERY
ELECTROSURGERY can be defined as the use of high frequency electric current
to severe tissue or achieve haemostasis. This is achieved with the intrinsic thermal
effect of the electric current.
A low frequency below 100 kHz can stimulate muscles and nerves. Putting it another
way a low frequency current can electrocute the patient.
Although the generator could perform ELECTROSURGERY quite well at frequencies
up to 4 MHz, reactive phenomena, capacitance and inductance become quite
prominent at such high frequencies and it becomes difficult to confine these high
frequency currents to wires.
For these reasons, Maestro Plus 100 works at 350 kHz which is a compromise
between these two extremes.
