Endoscopic Procedures III: Video Capsule Endoscopy

159
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

88
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

    Area of Science:

    • Medical Engineering
    • Robotics
    • Human-Computer Interaction

    Background:

    • Endoscopes are crucial for minimally invasive inspections but challenging to operate intuitively due to embodiment differences.
    • Existing endoscope control systems often lack intuitive feedback, hindering precise manipulation during procedures.

    Purpose of the Study:

    • To develop and validate an endoscope operating system with a novel Cartesian coordinate input interface.
    • To quantify the accuracy and range of motion of the developed endoscope system for clinical applications.

    Main Methods:

    • Development of a Cartesian coordinate input interface for endoscope control.
    • Utilized a magnetic three-dimensional positioning sensor to measure endoscope tip movement.
    • Compared actual endoscope tip positions and postures with estimated values to calculate errors.

    Main Results:

    • The developed endoscope operating system demonstrated sufficiently small thrust output errors.
    • Required accuracy was achieved within a specific range of motion: -74.9° to 80.0° (roll) and -37.5° to 50.0° (yaw).

    Conclusions:

    • The novel Cartesian interface provides an accurate and intuitive method for endoscope operation.
    • This system has significant clinical relevance for improving precision in endoscopic procedures.
