Arc generating electrosurgical instrument
Abstract
Abstract An electrosurgical instrument for the contactless outer surface coagulation of biological tissue employs an arc discharge generated by a high-voltage external source at high frequency. The hand-held instrument housing (11) contains a central treatment electrode (12) at its insulated (11') operational end (13) energised via an insulated (14) conductor (12') from an input terminal (15) and supported by the spiders (16). A stable arc control regime surrounding the electrode (12) is effected by an atomiser assembly at the opposite-electrode end. This uses a compressed carrier gas e.g. air or CO2 or N2 which forms an aerosol suspension (22) of a dilute salt solution in the manner of a carburettor via the nozzles (18,17) respectively.
