ENDOSCOPIC DEVICE INCLUDING CLEANING MECHANISM

摘要

In a cleaning mechanism provided in an insertion section of an endoscopic device, two straight lateral faces obliquely and straightly extending toward the center side of a cylindrical lens are joined to a laterally circumferential face, a pedestal section inside which a liquid-sending route of a cleaning liquid, and a gas-sending route are internally provided is arranged, and an angle which a gushing direction of the cleaning liquid gushed from each of wash nozzles provided on the lateral faces toward the laterally circumferential face forms with a perpendicular line passing through the center of the cylindrical lens is an acute angle, the gushed cleaning liquid intersecting the perpendicular line.
