  • Patent number: 4998538
    Abstract: A disposable medical drape adapted for use in laser surgery is configured to form an enclosure, acting as an emission barrier, between the medical laser and the patient tissue to be removed so as to contain, within the enclosure, materials present in the laser plume. The drape includes a floor having an opening therein which defines the target area of patient tissue. The floor includes moisture-absorbent material which is premoistened to protect the patient from errant laser shots. The underside of the floor includes an adhesive material for fixing the floor of the drape directly to the skin of the patient. The drape includes flexible transparent walls which extend from the floor of the drape to the medical laser, the walls including stiffening rings to define an obstruction-free corridor for the laser beam. The walls of the drape are gathered around the barrel of the medical laser so as to prevent emissions at that juncture.
