    New endoscopic couplers enhance safety in laser surgery. These innovative devices improve visualization and control for laparoscopic, arthroscopic, and bronchoscopic procedures.

    Area of Science:

    • Minimally Invasive Surgery
    • Surgical Instrumentation
    • Laser Technology

    Background:

    • Traditional endoscopic procedures can be limited by visualization and instrument control.
    • Existing endoscopic couplers may lack integrated safety features.
    • Advancements in laser surgery necessitate improved accessory devices.

    Purpose of the Study:

    • To design and present a novel set of endoscopic couplers for various laser surgical applications.
    • To incorporate unique safety features not previously available in endoscopic couplers.
    • To enhance surgeon control and visualization during laser-guided endoscopic interventions.

    Main Methods:

    • Development of specialized endoscopic couplers for laparoscopic, arthroscopic, and bronchoscopic surgery.

  • Integration of a gimbeled, partially reflective germanium window in the bronchoscopic coupler for coaxial vision.
  • Inclusion of a "joy stick" control for precise manipulation of the helium-neon aiming laser within the bronchoscope.
  • Testing with small-diameter bronchoscopes (4 mm) and varying lengths (30-40 cm).

    • Main Results:

    • Successful design and implementation of a new range of endoscopic couplers.
    • Incorporation of novel safety features enhancing surgical practice.
    • The bronchoscopic coupler provides direct, coaxial visualization of the laser beam.
    • The "joy stick" allows for accurate aiming laser manipulation within the bronchoscope lumen.
    • Compatibility demonstrated with small-caliber bronchoscopes.

    Conclusions:

    • The designed endoscopic couplers offer enhanced safety and improved operational control for carbon dioxide laser surgery.
    • The innovative features, particularly in the bronchoscopic coupler, advance the capabilities of minimally invasive procedures.
    • This new coupler design represents a significant improvement for surgeons utilizing laser technology in endoscopic interventions.
