Abstract

Abstract The speculum includes a first top blade and second lower blade, the blades moveable in relation to one another via a rear hinge portion, as with a normal speculum. The lower blade of the speculum is further provided with a liquid evacuator tube extending along the interior of the speculum with an open protruding from the front of the blade for evacuating fluid from the patient during the laser surgery, and the top blade is provided with a second tube which is smoke evacuator tube similar to the liquid evacuator tube for evacuating smoke from the patient during laser surgery. In the preferred embodiment there is provided a trap in the handle portion of the speculum wherein the liquid evacuator tube and the smoke evacuator tube deposit any materials which are evacuated from the patient, the trap also including the third tube to a "stack house" filter which serves as the source for the suction created by the liquid evacuator and smoke evacuator tube.
