Abstract:
An electrosurgical generator connectable with a power input, comprising:an input treatment network responsive to said power input to provide a first output; a frequency generator responsive to said first output and to a frequency control input to derive an output having a predetermined waveform; an output voltage control circuit responsive to a voltage level control input to derive an electrosurgical energy output at an electrosurgical voltage level and at an electrosurgical frequency; an output stage responsive to said output voltage control circuit electrosurgical energy output and connectable in electrical communication with an electrosurgical instrument having an electrode; and a control assembly responsive to a cut command to derive said voltage level control input to provide a boost electrosurgical voltage level effective to create a cutting arc at said electrode when embedded in animal tissue for a boost interval and thereafter deriving a normal cut electrosurgical voltage level which is less than said boost electrosurgical voltage level while remaining effective to sustain said cutting arc.
