Cosmetic RF surgery
View Patent ↗An electrode and procedure for removing skin lesions or blemishes comprising an electrode with a flat blunt active end which is applied to the skin lesion or blemish, while RF electrosurgical currents are applied to the electrode, in an up and down tapping motion in such manner that contact between the skin and the active electrode end is intermittent. Preferably, after a small number of skin taps with the electrode end, the tapped area is wiped with a wet gauze or cloth, and the procedure of intermittent tapping with the RF electrode interrupted with wet wipes is continued until the blemish disappears.
1. A procedure for improving the appearance of skin tissue of a patient by removing lesions, comprising the steps:
A. providing:
(a) a handpiece and an electrode comprising an elongated first member having a proximal first end mounted in the handpiece and a distal second end being the active end of the electrode,
(b) the second end being approximately at right angles to the first end and being bare and configured to form a flat blunt end;
B. providing a radio-frequency generating instrument for supplying radio-frequency currents in the megacycle range to the electrode when activated;
C. applying the flat blunt end of the electrode to the patient's skin tissue to be treated and continuously moving the electrode up and down in and out of contact with the skin surface such that radio-frequency currents are intermittently applied to the patient's skin by the electrode's active end while the radio-frequency instrument is activated to remove surface layers of the lesion being treated.
2. A procedure as claimed in claim 1 , further comprising the step of:
D. when surface layers of the lesion being treated have separated following step C, wiping off the separated tissue with a wet gauze;
E. repeating steps C. and D. until the lesion is substantially completely removed.
3. A procedure as claimed in claim 2 , wherein the bare active end of the electrode is constituted of an alloy primarily of silver.
4. A procedure as claimed in claim 3 , wherein the alloy is primarily of silver with small additions of germanium and indium.
5. A procedure as claimed in claim 1 , wherein the radio-frequency currents are at a frequency of about 3.8-4 MHz.
6. A procedure as claimed in claim 5 , wherein the radio-frequency currents are continuously rectified.
