Flexible endoscopes are complex, precision-engineered medical devices made up of many delicate components. Due to their intricate design, they are highly susceptible to damage if not handled correctly. While normal wear and tear from frequent use is expected, over 60% of the endoscopes we receive for repair are damaged due to improper handling and inadequate care.
Most Common Types of Endoscope Damage from Improper Handling
Improper usage and insufficient maintenance can lead to a wide range of issues, including:
- Broken Control Knobs, Control Body, and Connector: Excessive force or rough handling often results in cracked or non-functional controls.
- Repeated Holes in the Bending Rubber: Continuous strain or incorrect manipulation can lead to holes in the bending section of the endoscope.
- Kinks or Holes in Biopsy and Suction Channels: Mishandling these channels can compromise suction and biopsy performance.
- Insertion Tube Buckling, Dents, or Peeling: Forcing the insertion tube can cause structural damage and degradation of the outer coating.
- Light Guide Tube Crush or Light Fiber Damage: Overbending or pressing the light guide can crush the tube or damage internal fibers, affecting illumination.
- Fluid Invasion Damage: Inadequate reprocessing or cleaning techniques can lead to fluid infiltration, damaging internal electronics.
- Distal End Impact Damage: Dropping or knocking the distal tip against hard surfaces can cause serious damage to the lens or housing.
- Air/Water Nozzle Blockages: Poor cleaning practices can result in clogged nozzles, reducing air or water flow during procedures.
Normal Wear and Tear of Flexible Endoscopes
Even with proper care, flexible endoscopes will naturally experience wear over time. Common issues include:
- Occasional Bending Rubber Holes: Long-term use can lead to minor holes or cracks in the rubber.
- Angulation System Adjustments: The steering system may require tuning to maintain smooth movement.
- Worn or Weak Insertion Tubes: Age and frequent use can weaken the insertion tube, necessitating professional repair or replacement.
- Broken Wires and Angulation Failures: Continuous bending stresses can cause wire fatigue and steering malfunctions.
Best Practices to Prevent Endoscope Damage
To extend the lifespan and maintain the performance of your flexible endoscopes:
- Follow manufacturer-recommended cleaning, disinfection, and sterilization protocols.
- Train staff in proper endoscope handling techniques.
- Avoid excessive force during procedures or while cleaning.
- Conduct regular inspections and schedule preventive maintenance.
Proper care and maintenance are essential to protect your investment in endoscopic equipment. By handling your scopes with care and adhering to best practices, you can significantly reduce repair costs and maximize uptime.
