A liner element extends parallel to the sheath and inside the sheath at least along a distal end portion of the liner element. The liner element is insertable into a biopsy channel of the insertion member of the endoscope. The sheath and the liner element are attached at their distal ends by a transparent cap member to form a germ-tight seal. Biopsy channels expandable from a collapsed configuration to receive endoscopic surgical instruments during an operation are provided in or on the sheath.
