1. An electrosurgical apparatus comprising:

  • a housing having a passage extending therethrough, the housing having a proximal end and a distal end;

    a flow tube having a proximal end and a distal end, the flow tube being disposed in the passage of the housing;

    an insulating outer tube having a proximal end and a distal end, the outer tube disposed around the flow tube with the proximal end of the outer tube coupled to the distal end of the housing, the flow tube being movable along a longitudinal axis of the housing and outer tube;

    an electrode coupled to the distal end of the flow tube, anda transformer assembly disposed on the proximal end of the housing, the transformer assembly including a first transformer configured to receive electrosurgical energy at a first predetermined value from an electrosurgical generator and an external input configured to receive electrosurgical energy at a second predetermined value from the electrosurgical generator, the transformer assembly further including a first switch for selectively coupling at least one of the first transformer and the external input to the electrode for providing electrosurgical energy thereto.
