止に寄与する。[Embodiment] FIG. 1 shows the internal structure of the flexible tube 11 of the endoscope insertion portion. According to this, in the endoscope flexible tube 11, the optical members of the light guides 12 and 13 for guiding the illumination light and the image guide 14 for guiding the subject optical image and the angle wire.
15, 16, 17, 18, forceps raising wire 19, focus adjustment wire 20
Is provided. Furthermore, a forceps channel 21 into which forceps are inserted is provided. Angle wire 15,16,17,1
8. The forceps raising wire 19 and the focus adjusting wire 20 are movably inserted in the flexible sheath members 22, 23, 24, 25, 26 and 27. Each of the sheath members 22 to 27 is composed of a hoop member 30 having high elasticity as shown in FIG. The hoop member 30 is a steel material, for example, a rolled steel material formed by rolling a round wire formed of JIS SAS304 steel material is used as the material, and the sheath member 22 and the like are formed by tightly winding it into a tube shape. To be done. Since the hoop material 30 is formed by rolling a round wire, it is work-hardened and has a high tensile strength. For this reason, the hoop material 30 is made up of the sheath members 22-24.
Significantly improves the elasticity of the endoscope and contributes to preventing the flexible tube 11 from getting settled.
前記フープ材30は素材に密を巻回して構成されているが
第３図に示されるように素材を所定ピッチ開けて巻回し
て構成されたシース部材31が用いられても良い。The hoop material 30 is formed by closely winding the material, but as shown in FIG. 3, a sheath member 31 formed by opening the material with a predetermined pitch and winding the material may be used.
上記フープ材30の厚みは素材として用いられる丸線の径
より小さいのでシース部材自体の外径が太くなることは
ない。Since the thickness of the hoop material 30 is smaller than the diameter of the round wire used as the material, the outer diameter of the sheath member itself does not become thick.
