Description

上記目的を達成するために本発明の一態様における内視鏡システムは、凹部を有する測定対象物の各頂面に少なくとも一部が接触自在な軸部材と、前記頂面を測定の基準面とし、この基準面に接する前記軸部材から前記凹部の設定深さと同じ高さに突出する凸部とを有する測定用治具と、挿入部の先端に観察用の対物レンズを備えた内視鏡と、を具備し、前記測定用の治具は、前記内視鏡の観察位置となる前記挿入部の先端より前方に設けられ、前記内視鏡は、前記凹部に前記凸部を嵌入させたとき前記凹部の頂点と前記軸部材の接触の有無を観察する。 In order to achieve the above object, an endoscope system according to an aspect of the present invention includes a shaft member that can be at least partially in contact with each top surface of a measurement object having a recess, and the top surface as a measurement reference surface. A measuring jig having a convex portion protruding from the shaft member in contact with the reference plane to the same height as the set depth of the concave portion, and an endoscope having an observation objective lens at the tip of the insertion portion ; , comprising a jig for the measurement is provided in front of the distal end of the insertion portion to be observed position of the endoscope, the endoscope, when is fitted the protrusion into the recess The presence or absence of contact between the apex of the recess and the shaft member is observed.

Claims
