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.

Description

[0001] This application is a divisional application of the application with the application number 200510005848.4, the application date is January 27, 2005, and the invention title is "Endoscope Insertion Auxiliary Instrument and Endoscope Device". technical field [0002] The present invention relates to an endoscope insertion aid and an endoscope device, and more particularly to an endoscope insertion aid used when inserting an endoscope insertion portion into a body cavity, and an endoscope using the insertion aid. Looking glass device. Background technique [0003] When inserting the insertion part of the endoscope into the deep digestive tract such as the small intestine, if only the insertion part is pushed, it will be difficult to transmit the force to the tip of the insertion part due to the complicated curvature of the intestine, making it difficult to insert into the deep part. Therefore, an endoscope device has been proposed in which an insertion aid called a cann...
