Which of the following endoscopes is NOT classified as flexible?

The laparoscope is classified as a rigid endoscope, which contrasts with the other options that are flexible. Laparoscopes are typically used in minimally invasive surgical procedures to access the abdominal cavity through small incisions. These instruments allow surgeons to perform operations with precision but do not possess the flexibility that is characteristic of scopes intended for internal examinations.

In comparison, cystoscopes, gastroscopes, and colonoscopes are designed to be flexible, enabling them to navigate through the curves and turns of the urinary bladder, stomach, and colon, respectively. This flexibility is essential for visualizing these areas effectively without causing excessive trauma to the surrounding tissues. Understanding the distinctions between these categories of endoscopes is crucial for proper usage and application in medical settings.
