Part of speech: noun

Definitions

1. A type of medical instrument designed to visualize the interior of a hollow organ or cavity through a flexible tube equipped with a light and camera
2. Utilizing advanced imaging technology, this tool allows for both diagnosis and treatment within confined spaces of the body
3. Often employed in minimally invasive procedures, these devices provide real-time images and data for physicians during examinations and surgeries

Etymology: This is the plural of "endoscope," so the word itself is simply the plural form. The singular "endoscope" was coined in the 1850s from the Greek "endon," meaning "within," and "skopein," meaning "to look at" or "examine." Its earliest instruments were crude tubes with a light source, used to look into body cavities. The modern devices that the definition describes, with fibre-optic cameras and treatment tools, developed largely in the 20th century.
