Claim 13:
14. An electrosurgical apparatus comprising:
a housing having a passage extending therethrough, the housing having a proximal end and a distal end;
an electrically conducting tube having a proximal end and a distal end, the electrically conducting 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 electrically conducting tube with the proximal end of the outer tube coupled to the distal end of the housing; and
an electrode for electrosurgical cutting made of an electrically conducting material, wherein a proximal end of the electrode is connected to the distal end of the electrically conducting tube,
wherein in a first position of the electrode, the electrode extends beyond the distal end of the outer tube for electrosurgical cutting and, in a second position of the electrode, the electrode is retracted within the outer tube,
wherein the electrically conducting tube is adapted to conduct energy to the electrode for electrically energizing the electrode in the first position and the second position, and
wherein the electrically conducting tube is adapted to supply inert gas from the proximal end of the housing through the electrically conducting tube to the electrode for generating plasma in the second position.
