FLEXIBLE TUBE FOR ENDOSCOPE, ENDOSCOPE-TYPE MEDICAL INSTRUMENT, AND METHODS FOR MANUFACTURING SAME

WIPO Patent Application WO/2022/137985

A1

The present invention provides: a flexible tube that is for an endoscope, that has superior resilience, that is capable of maintaining adequate adhesion between a flexible tube base material and a polymer-coating layer covering the same when subjected to repeated bending, and that is unlikely to induce deterioration of resilience when subjected to repeated heating; an endoscope-type medical instrument equipped with such a flexible tube for an endoscope; and methods for manufacturing such a flexible tube and such an endoscope-type medical instrument.　This flexible tube for an endoscope comprises: a flexible tube base material (14) which is composed of metal; a porous layer disposed on said flexible tube base material; a primer layer disposed on said porous layer; and a polymer-coating layer disposed on said primer layer. The side of the polymer-coating layer (15) in contact with the primer layer contains at least one compound from polyamides, polyesters, polyurethanes, and polyolefins.
