Which endoscope repair should NEVER be attempted by reprocessing staff and must be sent to a qualified repair center?
Answer: Repairing a torn insertion tube sheath
Insertion tube sheath repairs require specialized tools and expertise; improper repair can compromise the leak-tight integrity of the endoscope.
A videoscope produces a blurry image despite cleaning the distal lens. What should be checked next?
Answer: The CCD or CMOS image sensor for damage
If lens cleaning does not resolve blurry imaging, the image sensor (CCD/CMOS) may be damaged and requires professional evaluation.
Why is it important to keep endoscope repair logs separate from reprocessing logs?
Answer: They serve different traceability and quality improvement purposes
Repair logs track maintenance history and recurring damage patterns, while reprocessing logs document infection control compliance — each serves a distinct quality and safety function.
What effect does repeated pinching of the insertion tube have on long-term endoscope function?
Answer: Causes internal channel collapse and wire damage
Repeated pinching compresses the insertion tube, potentially collapsing internal channels and stressing or breaking angulation wires over time.
During visual inspection before reprocessing, a reprocessor finds a small nick in the insertion tube. The correct action is to:
Answer: Remove the scope from service and send for repair
Any visible damage to the insertion tube sheath warrants immediate removal from service, as it compromises the protective barrier against fluid ingress.
What is the MOST common cause of air/water channel blockage in flexible endoscopes?
Answer: Residual biological material not removed during manual cleaning
Inadequate manual cleaning leaves residual biological material (protein, mucus) that dries and blocks narrow channels over time.
How should endoscopes be stored to prevent damage to the angulation wires?
Answer: Hanging vertically with controls in the neutral/relaxed position
Vertical hanging with controls in the neutral position prevents prolonged tension or kinking of angulation wires during storage.
