Inside a singleuse electrosurgerycauterising pen

This is a common tool used by surgeons to make clean cuts that don't bleed. It's a probe that uses high power RF energy to cut and cauterise simultaneously. • This is the single use sterile pen that connects to a very complex and expensive machine that provides the RF energy at a fairly high voltage. The return path for the current is a flat electrode stuck onto a suitable area of the patient's body. • At the frequencies involved there's no electric shock effect. Just heat or burning at the point of contact. Further investigation shows that you can get blade, needle, ball and loop electrodes. • If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- • http://www.bigclive.com/coffee.htm • This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty. • • • #ElectronicsCreators
