Abstract
The endoscope applicator according to the present invention allows lubricant to be supplied uniformly to the entire inner surface of the endoscope applicator without increasing the diameter of the endoscope applicator because the lubricant supply path is laid on the outer surface of the endoscope applicator extending from the base end portion to the tip portion of the endoscope applicator and a plurality of openings are formed in the lubricant supply path and endoscope applicator at predetermined intervals in such a way that their opening areas of the opening increase from the base end portion to the tip portion. Moreover, the endoscope apparatus according to the present invention can improve the maneuverability of the insert portion and applicator during pull-in operation. Furthermore, the endoscope apparatus according to the present invention makes it possible to determine pull-out force quantitatively.
