My dad is a doctor and has one of those tools. When I was a kid I opened it and sure enough there was an air core transformer. The power knob adjusted the power setting by sliding the primary up and down.
I'll see if he still has it and post some photos.

Subject: Re: [TCML] TC STREAMERS TO FINGERS - BURNS ARE NO MYTH
I had a mole removed from my cheek once and the device the doctor used
was indistinguishable from the typical hand-held "Tesla coil' leak
detector, even to the sharp point! Ate up the mole in just a few
seconds of intermittent application.
