摘要： A combination electrosurgical instrument and vibratory device provides simultaneous transmission of radiofrequency energy and vibratory ultrasonic energy via a simple efficient handpiece attachment enabling a surgeon to modulate all types of tissues with different degrees of effectiveness. The combination of the invention enhances the proven effectiveness of both radiofrequency and ultrasonic technology. In a preferred embodiment, a small unbalanced motor that vibrates when activated is used to cause an electrosurgical handpiece containing the electrosurgical electrode to vibrate as a whole and to transmit to the electrode ultrasonic energy. The invention is of especial value when applied to skin resurfacing, but will also be of value for tissue modulation, coagulation, hemostasis and other electrosurgical procedures.

摘要： The invention realizes a radio knife powered by an electronic circuit that operates with high-frequency current wherein said circuit comprises: a rectifier circuit (20) fed by the mains voltage that supplies rectified pulsating voltage (201) to a radiofrequency circuit (30); a radiofrequency circuit (30) capable of emitting an output current signal (301) with a constant frequency in the scale of the MHz, powering the radio knife by means of a radiofrequency transformer (40). Said radiofrequency circuit (30) is obtained by piloting a MOSFET (305) through a pilot circuit (306) comprising a quartz-operated oscillator whose oscillation frequency amounts to at least twice the usual operating frequency of the MOSFET. The pilot circuit (306) is controlled by microprocessor current control circuit (310) that takes a signal proportional to the current from a current sensor (308) positioned after the MOSFET (305) and is such as to maintain the radiofrequency circuit current limited to a value compatible with the power that can be dissipated by the MOSFET independently of any variation in the circuit load impedance.
