ABSTRACT:
The invention provides an electrosurgical unit comprising a radio-frequency power source and a pump, with the throughput of fluid expelled by the pump controlled by the RF power level setting and fluid flow rate setting. The invention also provides various electrosurgical devices which may be used with the electrosurgical unit. In one embodiment, the electrosurgical device comprises a first electrode tip spaced next to a second electrode tip with a portion of the first electrode tip facing the second electrode tip and a portion of the second electrode tip facing the first electrode tip, the first electrode tip and the second electrode tip both having a spherical distal end, and a fluid outlet arrangement to expel fluid onto the electrode tips solely at locations remote from the electrode tip portions facing each other.
