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 (322, 422) having a proximal end and a distal end, at least the proximal end of the electrically conducting tube (322, 422) being disposed in the passage of the housing; an insulating outer tube having a proximal end and a distal end, the insulating outer tube disposed around the electrically conducting tube (322, 422) with the proximal end of the insulating outer tube coupled to the distal end of the housing, the electrically conducting tube (322, 422) being movable along a longitudinal axis of the housing and insulating outer tube; and an electrode coupled to the distal end of the electrically conducting tube (322, 422), wherein, in a first position for electrosurgical cutting, the electrode extends beyond the distal end of the insulating outer tube and, in a second position, the electrode is retracted within the insulating outer tube and is energized via the electrically conducting tube (322, 422) to form plasma when an inert gas flows through the electrically conducting tube (322, 422), wherein the respective distal ends of the electrically conducting tube (322, 422) and the insulating outer tube are configured at a predetermined acute angle with respect to the longitudinal axis of the insulating outer tube, the distal end of the insulating outer tube being configured from a shape memory material; wherein the electrode is an electrically conducting blade tapered to a point at a distal end of the electrically conducting blade; characterised in that the apparatus further comprising a knob coupled to the insulating outer tube to effect rotation of the distal end of the insulating outer tube in 360° of rotation; the electrically conducting tube (322,422) being rotationally fixed relative to the longitudinal axis; and, either (a) the apparatus further comprises a spring configured to electrically and mechanically couple the electrode to the distal end of the electrically conducting tube (322, 422); or (b) wherein a portion of the distal end or the electrically conducting tube (322, 422) includes a plurality or cuts to enable articulation. a housing having a passage extending therethrough, the housing having a proximal end and a distal end;
