A proctoscope is defined as what?

A proctoscope is a short, rigid endoscopic instrument designed to visualize the distal part of the large intestine—the lower rectum and anal canal. Its typical length, about three inches, lets a clinician inspect this limited region without entering higher into the colon, which is exactly why the description “three-inch-long instrument used to examine the lower rectum and anal canal” fits best. The other options describe tools or purposes that don’t match the proctoscope’s specific use: measuring stomach pH is unrelated to rectal visualization, a camera for the colon implies a colonoscope, and instruments intended for broader rectal or colon examination point to other devices.
