Abstract
A flexible sheathing tube suitable for encasing an elongated flexible body like a flexible insertion rod of an endoscope or other insertion type examination instrument, and a method for fabrication of such sheathing tubes. The flexible sheathing tube being of the type is basically provided with a flexible base structure having at least an open helical coil member of a cylindrical shape, a protective mesh sleeve fitted on the helical coil member, and an insulating outer coating layer formed on the protective mesh sleeve. The sheathing tube is further provided with an inner coat layer of a resilient material formed on the inner side of the helical coil member in such a manner as to cover the inner periphery of the helical coil member completely, filling in gap spaces between open helices of the coil member.
