Read the first 6 Endoscope Design and Structure Questions and Answers flashcards as text

  1. What distinguishes a therapeutic endoscope from a diagnostic endoscope?

    Answer: Therapeutic endoscopes have larger instrument channels to accommodate therapeutic devices

    Therapeutic endoscopes have larger biopsy/instrument channels (typically 3.7–4.2 mm) to accommodate tools like snares, forceps, and hemostatic devices.

  2. Which structural feature of a bronchoscope makes it distinctly different from a gastroscope?

    Answer: Bronchoscopes have a smaller outer diameter and smaller instrument channel suited for airway anatomy

    Bronchoscopes are narrower in diameter to navigate the airways, which are much smaller than the GI tract.

  3. What is the purpose of the angulation section (bending section) at the distal end of a flexible endoscope?

    Answer: To allow the distal tip to be deflected in up to four directions for navigation and visualization

    The bending section, controlled by angulation knobs, allows the distal tip to be steered in up/down and left/right directions for navigation.

  4. Why are duodenoscopes considered a higher infection-transmission risk than colonoscopes or gastroscopes?

    Answer: The elevator recess creates a protected space that is difficult to clean and can harbor residual organisms

    The elevator mechanism in duodenoscopes creates a complex recess that is difficult to access with standard cleaning tools, enabling microbial survival.

  5. What does 'channel diameter' determine during endoscope reprocessing?

    Answer: The brush size required and the flow rate achievable during flushing

    Channel diameter determines which brush sizes are compatible and the volume of fluid that can be flushed through during cleaning.

  6. What is the significance of the endoscope's 'distal tip' during reprocessing?

    Answer: It houses the imaging chip, light guides, and channel openings, requiring meticulous cleaning of all ports

    The distal tip contains the imaging element, light guides, and all channel openings, making it one of the most critical areas for thorough cleaning.
