What effect does operating frequency have on electrosurgery?
Assuming operating frequency is high enough ( over 100kHz ), neuro-muscular stimulation is avoided. A higher frequency of 3.0mHz or more provides better efficiency for the capacitive dispersive pad in comparison to general surgery units which run around 1.0mHz or less and which rely on direct contact dispersive pads. However, figures given for low frequency general surgery units and for high frequency dental units show the same collateral tissue denaturing widths and the same healing times.
