Abstract

A multi-function arthroscope has a laser channel, an irrigation tube, a suction tube, a rod lens, and optical fibers housed within a tubular casing. The operation site is illuminated by the optical fibers, and the physician views the illuminated site through the rod lens, performs laser surgery with laser radiation propagated by the laser channel, irrigates the site and cleans the rod lens with saline solution through the irrigation tube, and vacuums the debris with the suction tube, all in a single insertion of the arthroscope through a dilator tube. The respective distal ends of the optical fibers, rod lens, laser channel, irrigation tube, and the suction tube are positioned in different planes so that the suction tube extends in a distal direction further than the laser channel, the laser channel extends further than the irrigation tube, and the irrigation tube extends further than the rod lens. Connector members join the laser channel, the irrigation tube, the suction tube, and the optical fibers and rod lens to an external source of coherent light, an external source of saline solution under positive pressure, an external source of negative pressure, and an external source of incoherent light, respectively.
