Abstract

Provided are: an adhesive for an endoscope which contains at least one epoxy resin (A) among bisphenol A epoxy resin, bisphenol F epoxy resin, and phenol novolac epoxy resins, a polyamine compound (B), and a specific compound having an epoxy group; a cured product of the adhesive for an endoscope; an endoscope produced using the adhesive for an endoscope; and an endoscope production method.

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 observing the inside of 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 chemicals every time it is used. [0003] In particular, when inserting into a site with a high possibility of infection, such as a bronchi, cleanliness at a high sterilization level exceeding the disinfection effect 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) has been expected. [0004] Also, the insertion portion of the endoscope is inserted into the body cavity through the oral cavity or th...
