Abstract:
An electro-surgical pencil comprising:
a housing forming an axially extending main suction passage from a proximal opening to a distal opening;
a tube forming an extension of the main suction passage from the proximal opening to a proximal extension opening, the tube being configured for telescoping movement through the proximal opening;
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 attached to the tube and forming a further extension of the suction passage.
Since both the tube and the suction tip are movable relative to the housing, a short and a long configuration can be obtained while good smoke removal capabilities are maintained.
