Abstract

An endoscope adhesive, a cured material, an endoscope, and a method for manufacturing an endoscope, the endoscope adhesive being a two-component endoscope adhesive having a main agent and a curing agent, wherein the main component includes at least one type of epoxy resin (A) from among a bisphenol-A-type epoxy resin, a bisphenol-F-type epoxy resin, and a phenol novolac-type epoxy resin, the curing agent includes a tertiary amine compound (B), and the ratio accounted for by the tertiary amine compound (B) among curing components included in the curing agent is 60% by mass or greater.

Description

technical field [0001] The present invention relates to an adhesive for an endoscope, a cured product, an endoscope and a method for manufacturing the endoscope. Background technique [0002] Endoscopes for viewing inside body cavities of the human body are used repeatedly. Therefore, the flexible tube constituting the insertion portion of the endoscope needs to be cleaned and sterilized with a drug every time it is used. [0003] In particular, when inserting into a site with a high possibility of infection, such as a bronchi, cleanliness with a high level of sterilization beyond disinfection is required. Therefore, not only the widely practiced sterilization treatment using EOG (ethylene oxide gas), but also the application of a treatment with higher sterilizing power (for example, hydrogen peroxide plasma treatment) is desired. [0004] In addition, the insertion part of the endoscope is inserted into the body cavity through the oral cavity or the nasal cavity. In orde...
