Electric discharge during electrosurgery

Electric discharge utilized for electrosurgery is studied by means of a recently developed method for the diagnostics of small-size atmospheric plasma objects based on Rayleigh scattering of microwaves on the plasma volume. Evolution of the plasma parameters in the near-electrode sheaths and in the positive column is measured and analyzed. It is found that the electrosurgical system produces a ...

Excision of rhinophyma with high-frequency electrosurgery.

BACKGROUND Rhinophyma is an uncommon progressive disfiguring process of the lower nasal region that most commonly affects middle-aged white men. It is characterized by painless hyperplasia of the sebaceous and subcutaneous tissues, in the end stage, resulting in a bulbous nodular telangiectatic nose. Surgical modalities of treatment include electrosurgery, laser ablation, dermabrasion, cryosurg...

Nanosecond plasma-mediated electrosurgery with elongated electrodes

Progress in interventional medicine is associated with the development of more delicate and less invasive surgical procedures, which requires more precise and less traumatic, yet affordable, surgical instruments. Previously we reported on the development of the pulsed electron avalanche knife for dissection of soft tissue in liquid media using the 100 ns plasma-mediated electric discharges appl...
