Abstract

Rigid carbon dioxide wave guides measuring 300 to 500 mm in length and 3.0 mm in diameter were evaluated in rabbits and humans. The wave guide provided an effective laser delivery system for operative laparoscopy. The tested guide was introduced into the abdominal cavity alternatively via the operating channel of a 9-mm operating laparoscope, through the central channel of a smoke evacuation/irrigation cannula, or via a 3.25-mm second puncture trocar. In contrast to previously tested flexible guides, the rigid device transmitted a visible helium-neon aiming beam, power up to 50 watts, and a beam diameter of less than 1 mm. The hollow guide was kept free of smoke by-products by continuous purging with carbon dioxide gas flowing at 800 to 1000 cc per minute. All wave guides could be sterilized by ethylene oxide gas or Cidex (Surgikos, Arlington, TX) soaking. Fourteen women with a variety of reproductive disorders underwent laser laparoscopy. The rigid wave guide was fired at distances ranging from less than 1 mm to 30 mm from the target and performed with maximal impact at distances of 3 to 5 mm. Perhaps the greatest advantage of this system is its ability to focus-defocus while directly coupling to the handpiece of standard lasers and requiring no special alignment procedures.
