1. An electrocautery and suction device comprising:
a housing connectable to a vacuum source, the housing including a suction cavity;
an electrocautery tip connected to the housing;
a suction tube assembly movable from a retracted position to an extended position relative to the housing, the suction tube assembly including a suction tip;
an actuator constructed and arranged to selectively form a vacuum in the suction cavity in cooperation with the vacuum source to exert a suction force on the suction tube assembly to cause the suction tip to move from the retracted position to the extended position; and
a click-lock mechanism constructed and arranged to mechanically lock the suction tip in the extended position upon triggering of the actuator, wherein the suction tip remains in the extended position upon release of the actuator and is constructed and arranged to mechanically unlock the suction tip upon triggering the actuator, wherein the suction tip moves into the retracted position.
