- 摘要：
PROBLEM TO BE SOLVED: To provide a guide tube used for a transnasal endoscope to help its insertion in a transnasal endoscopy.
SOLUTION: The guide tube 1 used for a transnasal endoscope has a nearly even shape in longitudinal section. The sectional shape of the guide tube 1 comprises pluralities of ribs 11 and inwardly folding thin walls 12. The thin wall 12 that is thinner than the rib 11 connects two each radially adjacent ribs 11. This guide tube 1 reduced in diameter by inwardly folding the thin walls 12 can expand its diameter when the inwardly folded thin walls 12 develop as the transnasal endoscope 3 is inserted.
