Abstract
Abstract The insertion end (30) of a scirroscope includes a sheath (3) a channel (4) for feeding water or passing a treatment instrument therethrough, an optics tube (6) in which an observation optical system is disposed, and a bundle (7) of optical fibers which defines an illumination optical system. An elastic member (21, 22, 23) covers either partly or entirely the internal periphery of the sheath (3) and/or the external periphery of the channel (4), the optics tube (6) and the fibre bundle (7). This renders the scirroscope more robust and less prone to cracking during sterilization.

A scirroscope including an observation and an illuminacion optical system both disposed in a sheath (3) characterized by an elastic member (21 - 26) which coats the internal periphery of the sheath (3) and/or the external periphery of at least one internally housed part (4, 6, 7,).
Claim 3
Dependent Claim
47 words
A scirroscope according to claim 1, in which the internally housed parts comprise a channel (4) which is used to feed water or to pass a treatment instrument, an optical tube (6) in which the observation system (5) is disposed, and a bundle (7) of optical fibres.
Claim 4
Dependent Claim
