FLEXIBLE ELECTRONIC ENDOSCOPE INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a flexible electronic endoscope instrument with which an observation object position in an endoscope observation image is easily specified when the endoscope observation image is examined later by detecting the position of the tip of an insertion part made of a flexible tube inserted into a human body without radiation exposure. SOLUTION: Each curve detection part 22 of an optical fiber 21 for detecting a curve where the transmitting quantity of light is varied corresponding to a curved angle is dispersedly arranged at the insertion part made of the flexible tube 1. A tip position detection means 40 for detecting the position of the tip of the insertion part made of the flexible tube 1 based on detected values obtained from the plurality of curve detection parts 22 is provided, and a combined storage preservation means 47 for combining the video signal of the endoscope observation image and positional information of the tip of the insertion part made of the flexible tube 1 when the video signal is obtained and storing and preserving them is provided.
