IMPROVED SEATH FOR USE WITH AN ENDOSCOPE

摘要

A sheath for a use in an endoscope is provided to reduce a number of steps required for a special medical process by decreasing the frequency to change a position of hands during an operation. In a flexible sheath(200) adapted to accommodate an endoscope, an external surface and an internal surface are included. The internal surface of the flexible sheath(200) is textured, not flat and has non-twist hardness. The internal surface of the flexible sheath(200) is relatively more textured than the external surface of the flexible sheath(200).
