Abstract:
1. A view optimizing assembly for use with a laparoscope having an objective lens for viewing a body cavity insufflated with CO 2 by an insufflator, the assembly comprising a cylindrical tube separate from the laparoscope and having a distal end, the cylindrical tube having an interior lumen configured to accommodate passage of the laparoscope to position the objective lens generally adjacent to the distal end during use and to accommodate removal of the laparoscope from the cylindrical tube after use, the cylindrical tube including a second interior channel separate from the pair of first interior channels, a lens guard projecting circumferentially forward and beyond the distal end of the cylindrical tube and including a first supply conduit having tubing configured to couple with the insufflator to divert a portion of the CO a second supply conduit configured to couple with a source of liquid, the second supply conduit coupled with a manually controlled actuator configured to convey the liquid through the second supply conduit, into the second interior channel, and through the second passage so as to direct a stream of the liquid across the objective lens in a second path different then the plurality of first paths to clear material from the objective lens, wherein residual droplets of the liquid may remain on the objective lens that are resistant to removal by the stream of diverted CO a manually activated pneumatic bulb coupled with the first supply conduit and configured to deliver a burst of CO
