Claim 0:
1. An electro-surgical pencil comprising:
a housing forming an axially extending main suction passage from a proximal opening to a distal opening, wherein the housing comprises (i) a main body forming the axially extending main suction passage and the distal opening, and (ii) a collar arranged about the proximal opening;
a tube with an internal conduit extending between a distal extension opening and a proximal extension opening and forming an extension of the axially extending main suction passage to the proximal extension opening, the tube being configured for telescoping movement through the proximal opening of the housing;
an electrode for cutting and/or coagulating tissue, the electrode being attached to the tube and extending axially from the proximal extension opening; and
a suction tip coupled to the tube and forming a further extension of the axially extending main suction passage,
wherein, while the electrode remains in a fixed position relative to the tube, the suction tip is configured for telescoping movement along an outer surface of the tube to adjust an extent by which the suction tip covers a portion of the electrode,
wherein the collar is rotatable about the main body to control movability of the tube relative to the housing,
wherein the collar is operable to adjust an amount of friction between an outer surface of the tube and an inner surface of the collar to lock and unlock the tube in the axially extending main suction passage, and
wherein the suction tip is slidable along the tube to a distal position at which at least a portion of the suction tip is received in a space between an inner surface of a proximal portion of the collar and the outer surface of the tube.
