A surgical instrument including a main unit and a suction conduit. The main unit includes at least one tubular body having a distal end, a proximal end, and an inlet disposed near the distal end. The suction conduit is slidably disposed over the main unit, and is slidably movable along the main unit between a retracted position, at which the suction conduit does not cover the inlet of the main unit, and an extended position at which the suction conduit covers the inlet of the main unit and a suction inlet of the suction conduit is placed in fluid-communication with the main unit inlet. The surgical instrument can be used as a suction tool by placing the suction conduit in the extended position and applying a vacuum through the inlet of the main unit and the suction inlet.
