A sheath device ( 1 ) suitable for endoscopic instruments ( 2 ) and comprising an elongated tubular member ( 4 ) having a proximal end ( 6 ), a distal open end ( 7 ), and at least one fluid channel ( 23 ). A flushing unit ( 5 ) is connected to the proximal end ( 6 ) of the tubular member ( 4 ) and comprises a proximal open end ( 8 ) suitable for receiving a first endoscopic instrument ( 2 ), a fluid inlet ( 16 ) in contact with said fluid channel ( 23 ), and a fluid outlet ( 17 ). The tubular member and the flushing unit together define a first interior guiding passage ( 10 ) for sheathing at least a part of said first endoscopic instrument ( 2 ). The connection between the tubular member ( 4 ) and the flushing unit ( 5 ) allows for axial rotation of the tubular member ( 4 ) in relation to the flushing unit ( 5 ). |
