Eyelid RF surgery
View Patent ↗A procedure employing non-ablative radio-frequency energy for improving the appearance of eyelids or the performance of eyelid blepharoplasty, and the monopolar electrode used in the procedure. The electrode is specially configured to provide a reasonably uniform electric field distribution at the skin surface when applied transconjunctivally on the inner surfaces of the upper or lower lids being treated. Preferably, the active end of the electrode forms a generally rectangular upward-facing platform. While RF electrosurgical currents are applied to the electrode, the platform surface is moved back and forth across and in contact with the tissue.
1. A surgical procedure intended to reshape the upper eyelid or lower eyelid for improving the appearance of skin tissue of a patient, comprising the steps:
A. providing:
(a) an electrode in the form of an elongated first member having a first end and a distal second end being the active end of the electrode,
(b) the first end being adapted for receiving a radio-frequency voltage capable of generating radio-frequency currents at the second end,
(c) the second end having a generally flat bare surface configured to form a platform surface extending approximately lateral to the first member, the platform surface being rectangular and planar, the platform surface having a range of lengths from about 0.18 to 0.30 inches, a range of widths from about 0.11 to 0.14 inches, and a range of heights from about 0.01 to 0.02 inches,
B. providing a radio-frequency generating instrument for supplying radio-frequency currents in the megacycle range to the electrode when activated;
C. connecting the first end of the electrode to the radio-frequency generating instrument;
D. applying the platform surface of the electrode to the patient's inside surface of the upper eyelid or lower eyelid to be treated and continuously moving the platform surface of the electrode back and forth while in contact with the inside eyelid surface such that radio-frequency currents are applied to the patient's tissue in contact with the platform surface while the radio-frequency generating instrument is activated to improve the appearance of the eyelid being treated.
2. A procedure as claimed in claim 1 , further comprising the step of:
E. adjusting the radio-frequency generating instrument to generate a rectified current waveform.
3. A procedure as claimed in claim 2 , wherein steps A-D are carried out following an eyelid blepharoplasty.
4. A procedure as claimed in claim 1 , wherein the radio-frequency currents are at a frequency of about 3.8-4 MHz.
5. A procedure as claimed in claim 4 , wherein the electrode has a curved shape.
6. An electrode for use in a surgical procedure intended to reshape the upper eyelid or lower eyelid for improving the appearance of skin tissue of a patient, comprising:
(a) an elongated member having a first end and a distal second end being the active end of the electrode,
(b) the first end being adapted for receiving a radio-frequency voltage capable of generating radio-frequency currents at the second end,
(c) the second end having a generally flat bare surface configured to form a platform surface extending approximately lateral to the first member,
(d) the electrode being monopolar,
(e) the platform surface being planar and generally rectangular with a length, width and height,
(f) wherein the platform surface has a range of lengths from about 0.18 to 0.30 inches, a range of widths from about 0.11 to 0.14 inches, and a range of heights from about 0.01 to 0.02 inches.
7. An electrode as claimed in claim 6 , wherein only the platform surface is electrically-conductive, the remainder of the second end being electrically-insulated.
8. An electrode as claimed in claim 6 , wherein the elongated member has a curved shape with the platform surface extending along the inside of the curve, the curved shape lying in a vertical plane.
9. An electrode for use in a surgical procedure intended to reshape the upper eyelid or lower eyelid for improving the appearance of skin tissue of a patient, comprising:
(a) an elongated member having a first end and a distal second end being the active end of the electrode,
(b) the first end being adapted for receiving a radio-frequency voltage capable of generating radio-frequency currents at the second end,
(c) the second end having a generally flat bare surface configured to form a platform surface extending approximately lateral to the first member,
(d) the electrode being monopolar,
(e) the platform surface being planar and generally rectangular with a length, width and height,
(f) wherein the platform surface has a length of about 0.25 inches, a width of about 0.13 inches, and a height of about 0.012 inches.
