Accepted Answer

Control body

Answer

Distal tip

Answer

Insertion tube

Answer

Light guide connector

Question 2

A reprocessor notices that an endoscope is failing to hold air pressure during a dry leak test. After checking all external connections and valves, the leak persists. Which internal component is MOST likely compromised?

Accepted Answer

Biopsy/suction channel

Answer

Objective lens

Answer

Light guide fibers

Answer

Video chip

Question 3

The primary function of the light guide connector and the associated fiber optic bundles within the endoscope's universal cord is to:
