<p>A tri-frequency electrosurgical device is provided to optimize an electrosurgical energy for cutting, coagulation, and fulguration by using a mono-polar mode or a bi-polar mode. A RF(Radio Frequency) power generating circuit is positioned inside a device console(8), and generates carriers of a first frequency, a second frequency, and a third frequency. A first electrical connector loads a mono-polar hand piece(26). A second electrical connector loads a bi-polar hand piece(28). A modulation circuit unit generates a first, a second, a third, and a fourth modulation waveform. A first unit selectively provides a first, a second, a third, and a fourth electrosurgical mode current of the first frequency to the first electrical connector or the second electrical connector. A second unit selectively provides a fifth, a sixth, a seventh, and an eighth electrosurgical mode current of the second frequency to the first electrical connector or the second electrical connector. A third unit selectively provides a ninth, a tenth, and an eleventh electrosurgical mode current of the third frequency to the first electrical connector or the second electrical connector.</p> |
