    A novel laparoscopic probe system enhances CO2 laser surgery by enabling simultaneous smoke evacuation and pneumoperitoneum maintenance. This shorter probe allows for greater power density application, simplifying procedures.

    Area of Science:

    • Minimally Invasive Surgery
    • Laparoscopic Technology
    • Surgical Laser Applications

    Background:

    • Laparoscopic surgery requires effective visualization and maintenance of pneumoperitoneum.
    • CO2 laser use in laparoscopy generates smoke, potentially obscuring the surgical field.
    • Existing instruments may limit the range of power densities applicable during procedures.

    Purpose of the Study:

    • To introduce a new second-puncture probe system for CO2 laser laparoscopy.
    • To evaluate the system's capability for simultaneous smoke suction and CO2 insufflation.
    • To assess the impact of the probe's design on power density application and surgical ease.

    Main Methods:

    • Design and integration of a novel second-puncture probe with a 200-mm focusing lens.

  • The probe facilitates simultaneous smoke evacuation and fresh CO2 insufflation for pneumoperitoneum.
  • Initial testing conducted on laboratory animals and patients with gynecological conditions.

    • Main Results:

    • The new probe system effectively manages smoke and maintains pneumoperitoneum during CO2 laser laparoscopy.
    • The probe's shorter length (10 cm less than standard) allows for a wider range of power densities.
    • Improved ease of surgical performance observed in initial applications.

    Conclusions:

    • The designed second-puncture probe system is a valuable advancement for CO2 laser laparoscopy.
    • It enhances surgical visualization and procedural efficiency through integrated smoke management and pneumoperitoneum.
    • The system shows promise for treating conditions like endometriosis and tubal obstructions.
