    A new CO2 laser handpiece offers surgeons enhanced precision for tissue cutting and ablation. This variable-spot-size device improves surgical accuracy and hemostasis during procedures.

    Area of Science:

    • Medical Devices
    • Surgical Technology
    • Laser Applications

    Background:

    • CO2 laser surgery is a widely used technique for tissue ablation and cutting.
    • Current handpieces may lack the flexibility for precise control over the laser spot size.
    • Achieving optimal hemostasis during laser procedures is crucial for minimizing blood loss.

    Purpose of the Study:

    • To introduce a novel variable-spot-size handpiece for CO2 laser surgery.
    • To evaluate the handpiece's efficacy in enhancing surgical precision.
    • To assess the impact of the handpiece on hemostasis during tissue ablation.

    Main Methods:

    • Design and development of a variable-spot-size handpiece with a sliding control mechanism.
    • Integration of the handpiece into a CO2 laser system.

    Related Experiment Videos

  • Inclusion of the handpiece in simulated or actual surgical procedures for evaluation.

    • Main Results:

    • The variable-spot-size handpiece allows for precise focusing and defocusing of the CO2 laser beam.
