CER Endoscope Repair and Maintenance 3

Question 1

Which endoscope repair should NEVER be attempted by reprocessing staff and must be sent to a qualified repair center?

Accepted Answer

Repairing a torn insertion tube sheath

Answer

Insertion tube sheath repairs require specialized tools and expertise; improper repair can compromise the leak-tight integrity of the endoscope.

Question 2

A videoscope produces a blurry image despite cleaning the distal lens. What should be checked next?

Accepted Answer

The CCD or CMOS image sensor for damage

Answer

If lens cleaning does not resolve blurry imaging, the image sensor (CCD/CMOS) may be damaged and requires professional evaluation.

Question 3

Why is it important to keep endoscope repair logs separate from reprocessing logs?

Accepted Answer

They serve different traceability and quality improvement purposes

Answer

Repair logs track maintenance history and recurring damage patterns, while reprocessing logs document infection control compliance — each serves a distinct quality and safety function.

Question 4

What effect does repeated pinching of the insertion tube have on long-term endoscope function?

Accepted Answer

Causes internal channel collapse and wire damage

Answer

Repeated pinching compresses the insertion tube, potentially collapsing internal channels and stressing or breaking angulation wires over time.

Question 5

During visual inspection before reprocessing, a reprocessor finds a small nick in the insertion tube. The correct action is to:

Accepted Answer

Remove the scope from service and send for repair

Answer

Any visible damage to the insertion tube sheath warrants immediate removal from service, as it compromises the protective barrier against fluid ingress.
