Flexible tube of endoscope

Abstract

Abstract A flexible tube of an endoscope adapted to be inserted in a body cavity includes a flex made of helically wound metallic strip to prevent collapsing of the tube, a cylindrical braid fitted over the flex, a metallic annular end piece secured with each end of the flex and the braid, and a plastics sheath secured on the outer surface of the braid. The cylindrical braid is braided by a plurality of metallic wires and a plurality of heat-resistant, chemicals-resistant non-metallic fibres. Thus, the sheath is adhered to the non-metallic fibres and the end piece is soldered with the metallic wires without affecting the non-metallic fibres by soldering heat and soldering flux.
