Electrosurgey is widely used in different modes such as cutting, coagulation or a blend of these.
The basic nature of power to these are AC. The AC Voltage ranges from 250KHz to 1.5Mhz. It is belived that above 60Hz the effects of voltage on muscle stimulation in the body is reduced to safe levels.
But there also is a concept of AC Current Heating. Some of the literature suggests that as the freq of AC voltage is increased the heat(currrent density) proportionally increases...
Is anyone aware of the equation that governs the above heating effect..
(I use i*i*R*t for all calculations :? )
