ABSTRACT:
A cervical speculum of the type having a first upper blade and a second lower blade, the blades movable in relation to one another via a rare hinge portion, and having the ability to be adjustable and used in conjunction with the gynecological procedure of, for example, surgery on the cervix. The improvement would include a pair of evacuator tubes which would be adaptable to the interior surfaces of the upper and lower blades respectively, each of the tubes having an adhesive material on that portion of the tube that would make adhesive contact with the surfaces of the upper and lower blades, with the tubes extending with their open ends at the ends of each of the blade portions, and extending rearwardly to the ends of the blades that are hingedly attached. Each of the tubes would lead into an evacuator tube, leading into an evacuator trap or line, so that the trap may be connected to a "stackhouse" filter which is the source of suction to evacuate the smoke and fluid from the patient's vaginal cavity during surgery. There may be further included a trap means so that the heavier liquids are contained in the trap, and the smoke from the laser surgery would be evacuated into the "stackhouse" filter for removal. The entire unit would be easily adaptable to an exisiting cervical speculum in order to allow use of existing speculums for this particular procedure.
