A new second-puncture probe for CO2 laser laparoscopy

A new second-puncture probe system was designed for aiming and firing the CO2 laser under laparoscopic control. The probe allows simultaneous suction of the smoke from vaporization and insufflation of fresh CO2 for maintenance of an adequate pneumoperitoneum during use. A 200-mm focusing lens attaches the probe to any surgical CO2 laser with an articulated arm. The new probe is 10 cm shorter than standard probes, allowing the application of a wider range of power densities during laser laparoscopy and making surgery easier to perform. Our initial experiences with this new instrument have involved both laboratory animals and patients with endometriosis, adnexal adhesions and distal tubal obstruction.
