    Area of Science:

    • Medical Devices
    • Gastroenterology
    • Robotics

    Background:

    • Endoscopic examinations of the upper and lower digestive tracts are crucial for diagnosis and treatment.
    • Current endoscopic tools can face challenges navigating complex anatomical structures like curves and flexures.
    • A need exists for improved maneuverability and ease of use in endoscopic instruments.

    Purpose of the Study:

    • To describe a novel carrier system for endoscopic instruments.
    • To introduce a mechanism for enhanced control and navigation within the digestive tract.
    • To facilitate easier and more effective endoscopic examinations.

    Main Methods:

    • Development of a carrier composed of articulated segments.
    • Integration of magnetic clutches to control angular displacement between segments.
    • Implementation of a system where the leading segment's angle is automatically replicated by subsequent segments.
    • Inclusion of a central channel for instrument passage.

    Main Results:

    • The carrier demonstrates the ability to navigate curves and flexures effectively.
    • The magnetic clutch system allows for precise control over the carrier's articulation.
    • The automatic angle replication ensures consistent guidance along the entire carrier length.
    • The central channel accommodates standard endoscopic instruments.

    Conclusions:

    • The described endoscopic carrier offers a significant advancement in navigating the digestive tract.
    • This technology has the potential to simplify endoscopic procedures, particularly in the upper and lower digestive tracts.
    • The innovative design promises to enhance the ease and efficiency of endoscopic examinations.
