Abstract
The present invention relates to an endoscope cover-sheathed endoscope having an endoscope in which an insertional part is extending from an operational part, and an endoscope cover made up of an insertional part cover, an operational part cover, and a universal cord cover, which shield the endoscope and are concatenated in that order from the distal end of the endoscope. The operational part cover overlaps and shields the margin of the insertional part cover, while the operational part cover overlaps and shields the margin of the universal cord cover. The endoscope will not therefore be bared. PA1 The proximal portion of an insertional part cover skin of the insertional part cover, which shields the insertional part and consists of a distal part, an insertional part cover skin, and an operational endoscope cover locking cap, is formed as a rigid skin made of Teflon, urethane, or other resin having such rigidity that will not cause a damage resulting from friction with other member, for example, a rigid sheath.
