Medical drape for laser surgery
First Claim
1. A medical drape for use in a medical procedure wherein a laser is employed to remove tissue from a patient, said drape comprising:
- (a) an enclosure extending between the laser and the patient tissue to be removed, said enclosure defining a substantially enclosed space between the laser and the patient tissue;
(b) said enclosure including target area boundary means for encircling a target area of patient tissue to be removed, said target area boundary means defining an opening in said enclosure; and
(c) said enclosure including containment means for substantially retaining, in said enclosed space, material resulting from laser removal of patient tissue.

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. The walls of the drape include suction ports adapted to be used with evacuation equipment for removing laser plume materials from the enclosure and creating a negative pressure therein. The walls of the drape also provide access to the patient tissue. The material of the drape is nonflammable.

18. A medical drape for use in a medical procedure wherein a laser is employed to remove tissue from a patient, said drape comprising a floor proximate the patient, said floor including opening means for surrounding the patient tissue to be removed, and an elongate sleeve having first and second ends defined by an endless sleeve wall, said floor attached to said first end of said sleeve so as to close said first end of said sleeve, said second end of said sleeve closed so that said sleeve and said floor together substantially define an enclosed space, said sleeve and said floor cooperating as containment means for retaining, in said enclosed space, material resulting from laser removal of patient tissue.

19. A method for containing emissions resulting from removal of patient tissue by laser beam, said method comprising providing an enclosure which defines an enclosed space extending between the laser and the patient tissue to be removed, said enclosure including opening means for encircling the patient tissue to be removed;
- affixing said enclosure to said patient so that said opening means encircles the patient tissue to be removed; and
attaching said enclosure to the laser so that a laser beam from the laser has an unobstructed path to the patient tissue to be removed, said enclosure acting as containment means for retaining, in said enclosed space, material resulting from laser removal of patient tissue. - View Dependent Claims (20, 21)
