Abstract

An endoscope (1) is provided with: a hard tip part (33), which is provided on the tip of an inserted section (2) and has a through hole (33a) passing through from the inside to the outside; a long image pickup part (23), which is provided inside the inserted section and the tip of which is inserted in the through hole and fixed; a light guide fiber bundle (28), which is provided inside the inserted section and has a molded tip section (M) that is molded such that the external form of the tip of the light guide fiber bundle has a previously prescribed shape according to the other structures inthe inserted section and that is inserted and fixed in the through hole; and a first LG covering tube (29) made of stretched porous polytetrafluoroethylene for covering the light guide fiber bundle from the molded tip section to at least the inside of the inserted section.

Description

technical field [0001] The present invention relates to medical or industrial endoscopes. Background technique [0002] Conventionally, endoscopes configured to have an insertion portion in the shape of an elongated tube have been widely used in, for example, the medical field and the industrial field. Among them, the medical endoscope used in the medical field is configured so that the insertion part can be inserted into the body cavity of a subject such as a living body to observe organs, etc., or use the organs, etc. The treatment instrument included in the speculum passes through the treatment instrument inserted into the channel to perform various treatments. In addition, the industrial endoscope used in the industrial field is configured so that the insertion part can be inserted into the inside of the subject such as a jet engine, factory piping, etc., or mechanical equipment, and the state of the subject such as damage and corrosion Wait for the status to observe a...
