  • Preclinical evaluation included various surgical procedures in a rat model (n=50), recording surgical time, blood loss, and injury incidence.
  • Clinical evaluation involved integrating the laser system into four meningioma resection cases.

    • Main Results:

    • Successful integration of contact laser technology with robotic assistance in microsurgery was demonstrated.
    • Preclinical studies showed improved microsurgical performance and reduced thermal damage with the laser.
    • The neuroArm system reduced surgeon variability, and clinical cases confirmed the system's utility in meningioma resection.

    Conclusions:

    • The combination of laser and robotic technology provides a consistent, expedient, and precise tool for microsurgery.
    • This integrated system has significant potential for advancing neurosurgical procedures.
    • Further development and application of this technology could lead to improved surgical precision and patient safety.
