damped sine wave

damped sine wave

the intermittent energy wave pattern from an electrosurgery unit used to achieve fulguration, desiccation or coagulation of soft tissues (see Table 1); energy that cuts through tissue and achieves simultaneous homeostasis from a moderately damped sine wave allows 'bloodless' surgery
Table 1: Forms of electrosurgery
Electrosurgery typeFeatures
ElectrofulgurationUses a high-voltage, dampened waveform to produce a spark that arcs from the probe tip to the skin lesion, causing superficial charring of the lesion surface
ElectrosectionUses an undampened or mildly damped current in conjunction with a very fine emitting electron to produce a cutting effect through soft tissue
ElectrocoagulationUses an intermittent damped current in conjunction with a larger emitting electrode to produce less intense heat over a larger area to induce coagulation and thereby haemostasis
ElectrodesiccationUses an intermittent damped waveform with high voltage and a lower current emitted from a ball electrode to induce cell dehydration and tissue shrinkage

Rather, the TASER M26 output is a pulsed, damped sine wave current with a frequency equivalent to 50,000 Hz.
