ABSTRACT:
An applicator for an electrosurgical instrument, alternatively for argon-plasma coagulation and cutting, also argon-supported. The applicator includes a gas and high frequency current terminal, a cutting electrode attached to a gas and high frequency current supply pipe, an insulating cap for detachably fastening the applicator on the instrument handle, and an insulating casing tube displaceable relative to the applicator common longitudinal axis for exposing or covering the cutting electrode and surrounding the gas and high frequency current supply pipe over a longitudinal section, and a collar or an external right-angle bend at the casing tube distal end. At least one radially surrounding gas-sealing inhibiting device is arranged between an inside of the casing tube and an outside of the gas and high frequency current supply pipe, allowing that a respective position be frictionally fixed at any location of the displacement path of the casing tube.
