ENDOSCOPE SYSTEM, ENDOSCOPE DEVICE, AND PROCESSOR

摘要

In order to provide technology in an endoscope system to make it possible to find the insertion length of an endoscope device by means of a simple configuration, there is provided an endoscope system that acquires images of the inside of a body cavity of a subject by insertion of an insertion section of an endoscope device into the body cavity, wherein an oscillator (5) outputs oscillation pulse signals and receives reflected pulse signals. Transmission lines (9) are provided along the insertion section (4) near the outer covering of the insertion section (4) and transmit the pulse signals output from the oscillator (5). A time calculation unit and an insertion length calculation unit (31) find the time difference between the oscillation pulse signals and the reflected pulse signals on the basis of the oscillation pulse signals output by the oscillator (5) and the reflected pulse signals received by the oscillator (5) and calculate the insertion length of the insertion section (4) on the basis of the time difference found.
