CER Endoscope Repair and Maintenance Questions and Answers 5

Question 1

Which type of endoscope damage is typically classified as 'functional' rather than 'cosmetic'?

Accepted Answer

Impaired suction due to a partial channel obstruction

Answer

Impaired suction from a channel obstruction directly affects clinical performance and patient safety, making it a functional defect requiring immediate repair.

Question 2

What is the purpose of the endoscope's universal cord water-resistant cap during reprocessing?

Accepted Answer

To protect the electrical light guide connector from fluid exposure during immersion

Answer

The water-resistant cap seals the electrical contacts of the light source connector to prevent fluid ingress and short-circuit damage during immersion reprocessing.

Question 3

A flexible endoscope returned from repair should be subjected to which test before returning to clinical use?

Accepted Answer

A full reprocessing cycle followed by leak testing and functional verification

Answer

After repair, the scope must undergo complete reprocessing, leak testing, and functional checks to confirm it is both safe and clinically ready.

Question 4

When evaluating endoscope image quality, 'salt and pepper' artifact in the center of the image most likely indicates:

Accepted Answer

Damage to the CCD/CMOS chip pixels

Answer

Dead or hot pixels on the CCD/CMOS image sensor appear as fixed 'salt and pepper' noise in the center of the image, indicating sensor damage.

Question 5

Which practice helps prevent 'scope pooling' damage in an endoscopy unit?

Accepted Answer

Rotating scope usage evenly and tracking each scope's procedure count

Answer

Rotating scope usage evenly prevents individual scopes from accumulating disproportionate wear, extending the fleet's overall lifespan.
