Abstract
An apparatus and a method are provided in which a cylindrical body is shaped and sized to sealingly and closely fit into a conventional cannula. An elongate surgical instrument is inserted into the cylindrical body through a resilient seal so as to extend past and be in pressing contact with distal ends of a plurality of bristles supported to the cylindrical body inside a distal end thereof. The sealing element and the bristles cooperate to support the surgical instrument substantially axially of the cylindrical body and the cannula within which it is contained. Relative motion of the surgical instrument causes a rubbing action of the bristles contacting its outer surface and this serves to remove any incidental surgical debris, e.g., excised tissue, coagulated fluids, and the like, from the bristle-contacted outer surface of the surgical instrument both when it is moved during use and when it is removed from the cylindrical body.
