<p>#CMT# #/CMT# The device (20) has several curved rigid portions (272,273) with predetermined spatial configuration. The curved rigid portions enable direct or indirect mechanical connection of an inner shaft (16) and outer shaft (17) before insertion of the light guide device in the endoscope. Several optical fibers (30) are provided in curved rigid portions, with varying cross-sections in light propagation directions (46,47). #CMT# : #/CMT# Independent claims are included for the following: (1) endoscope; and (2) method for manufacturing light guide device for endoscope. #CMT#USE : #/CMT# Light guide device for endoscope (claimed). #CMT#ADVANTAGE : #/CMT# Damage of the light guide device can be detected and prevented in advance, so that manufacturing cost and manufacturing time are reduced. Mechanical stress applied to the light guide device is reduced, so that service life is increased. Illuminating efficiency of the light guide device is increased. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the schematic views of the light guide device. 16 : Inner shaft 17 : Outer shaft 20 : Light guide device 30 : Optical fiber 46,47 : Light propagation directions 272,273 : Curved rigid portions.</p> |
