Causes of Endoscope Damage

Flexible endoscopes are intricate devices comprised of numerous components, making them susceptible to damage. While wear and tear over time or extensive usage can contribute to endoscope deterioration, it is important to note that a significant portion of endoscopes sent to our company for repair—more than 60%—have been damaged due to incorrect handling and inadequate care.

Improper handling and care can result in various issues, including:

  1. Broken Knobs, Control Body, Connector: Rough handling or excessive force can cause these parts to break or malfunction.
  2. Repeated Holes in Bending Rubber: Repeated stress or misuse can lead to the development of holes in the bending rubber portion of the endoscope.
  3. Repeated Biopsy/Suction Channel Kinks or Holes: Improper handling of the biopsy or suction channels can cause kinks or holes to form, hindering functionality.
  4. Insertion Tube Buckling, Dents, Bites Peeling: Mishandling or forceful insertion can cause the insertion tube to buckle, develop dents, or result in peeling of protective layers.
  5. Light Guide Tube Crush, Light Fiber Damage: Applying excessive pressure or bending the light guide tube can result in crushing or damage to the delicate light fibers.
  6. Fluid Invasion Damage: Failure to follow proper cleaning and disinfection procedures can lead to fluid invasion, causing damage to internal components.
  7. Distal End Impact Damage: Accidental impacts or collisions with hard surfaces can result in damage to the distal end of the endoscope.
  8. Air/Water Nozzle Clogs: Inadequate cleaning or failure to remove debris can lead to clogs in the air/water nozzles, affecting functionality.

Additionally, damage resulting from everyday use may include:

  1. Occasional Holes in Bending Rubber: Over time, the bending rubber may develop occasional holes due to normal wear and tear.
  2. Some Angulation System Adjustments: The angulation system may require occasional adjustments to maintain optimal performance.
  3. Insertion Tubes That Are Worn and Weak Due to Age and Use: Prolonged use can result in wear and weakening of the insertion tubes, necessitating repair or replacement.
  4. Broken Wires, Angulation System Failures: Constant flexing and strain can lead to wire breakage or failures in the angulation system.

It is essential to handle flexible endoscopes with care, following proper cleaning and sterilization protocols, and ensuring appropriate usage techniques to minimize the risk of damage. By doing so, you can extend the lifespan and maintain the performance of your valuable endoscopic equipment.
