Abstract

The endoscope (1) has: a front end rigid part (33), which is arranged on the front end of the insertion part (2), and has a through hole (33a) penetrating from the inside to the outside; an elongated imaging part (23), which is set Inside the insertion part, the front end is fixed in a state of being inserted into the through hole; the optical fiber bundle (28), which is arranged inside the insertion part, has a shape of the front end that is shaped in advance according to other structures in the insertion part. A front-end molding part (M) of a predetermined shape, which is inserted and fixed in the through hole; and a first LG covering tube (29) made of stretched porous polytetrafluoroethylene, which is inserted from the front-end molding part to at least The inner range of the part is covered with optical fiber bundles.

Description

Technical field[0001]The present invention relates to an endoscope for medical or industrial use.Background technique[0002]Conventionally, endoscopes configured to have an insertion portion in the shape of an elongated tube have been widely used, for example, in the medical field and the industrial field. Among them, medical endoscopes used in the medical field are configured to be able to insert the insertion part into the body cavity of a subject, such as a living body, to observe organs, etc., or to insert the organs and the like into the body as needed. The treatment tool included in the endoscope penetrates the treatment tool inserted into the channel to perform various treatments. In addition, the industrial endoscope used in the industrial field is configured to be able to insert the insertion part into the interior of a subject such as a jet engine, factory piping and other devices or mechanical equipment, etc., to the state of the subject such as damage and corrosion. Wait ...
