A novel robotic endoscope offers wide-angle visualization without rotation, enhancing surgical safety and observation in confined spaces. This technology promises significant advancements for clinical endoscopic procedures.

Area of Science:

  • Medical Robotics
  • Surgical Endoscopy
  • Optical Engineering

Background:

  • Current endoscopic methods often require mechanical manipulation (rotation/bending) to alter the field of view.
  • This manipulation increases the risk of accidental organ contact during minimally invasive procedures.
  • Limited maneuverability can restrict extensive observation within confined anatomical spaces.

Purpose of the Study:

  • To develop an innovative robotic endoscope with a wide-angle view.
  • To eliminate the need for endoscope rotation or bending for field-of-view adjustments.
  • To enhance surgical safety and observational capabilities in confined surgical sites.

Main Methods:

  • The system integrates a zoom-equipped endoscope with two independently rotating wedge prisms at its tip.

Related Experiment Videos

  • Each prism is mounted on a dedicated sleeve, allowing for precise, independent rotation around the endoscope's axis.
  • This design facilitates dynamic adjustment of the viewing angle without altering the endoscope's physical orientation.

    • Main Results:

    • In vivo experiments demonstrated high-quality imaging capabilities.
    • The endoscope enabled comprehensive observation of nearly the entire liver without requiring repositioning of the instrument.
    • The robotic system successfully provided a wide field of view with stable, clear imagery.

    Conclusions:

    • The developed robotic wide-angle endoscope system enhances surgical safety by minimizing the risk of accidental organ contact.
    • High-quality imaging and extensive observational capacity are key benefits for clinical applications.
    • This technology holds significant potential for advancing robotic endoscopic surgery and future clinical practice.
