DISTAL END RIGID SECTION OF INSERTION PORTION OF ENDOSCOPE AND ENDOSCOPE |
摘要 |
A distal-end rigid section of an insertion section of an endoscope, includes: a first base of a metallic material, which constitutes a distal-end portion of the insertion section of the endoscope; a second base of a resin material, which is formed on an axially proximal-end side of the first base; a cylindrical portion protruding from the second base toward an axially distal-end side of the first base and including a non-circular hole portion in which an illumination light source having a non-circular outer shape, generating light and emitting illumination light is disposed; and a through-hole formed by opening a part along an outer peripheral surface of the first base, the cylindrical portion being disposed in the through-hole such that the illumination light is emitted to the axially distal-end side of the first base. |

1. A distal-end rigid section of an insertion section of an endoscope, the distal-end rigid section comprising:
a first base of a metallic material, which constitutes a distal-end portion of the insertion section of the endoscope; a second base of a resin material, which is formed on an axially proximal-end side of the first base; a cylindrical portion protruding from the second base toward an axially distal-end side of the first base and including a non-circular hole portion in which an illumination light source having a non-circular outer shape, generating light and emitting illumination light is disposed; and a through-hole formed by opening a part along an outer peripheral surface of the first base, the cylindrical portion being disposed in the through-hole such that the illumination light is emitted to the axially distal-end side of the first base. |
