Abstract
An endoscope consists of a sheath having a passage extending therethrough, a water-feeding inlet portion and a water-draining outlet portion disposed near the proximal end portion of the sheath and each having a valve. The inlet portion and the outlet portion are provided with connection hoses each consisting of two layers of flexible coil tubes. The flexibility of the connection hose can set the inlet and outlet portions in any direction, thereby enabling the endoscope to be easily handled without being obstructed by the inlet and outlet portions.
