Abstract:
1. A blood vessel cutting device comprising: a sheath main unit including a distal end, a proximal end, and a longitudinal central axis extending to the proximal end from the distal end; a blood vessel cutter configured to be movable in the sheath main unit along the longitudinal central axis, and including a blood vessel cutting section outwardly extending from the distal end of the sheath main unit and configured to cut off a blood vessel; and a blood vessel holder including a blood vessel holding portion outwardly extending from the distal end of the sheath main unit and configured to hold the blood vessel, the blood vessel holding portion being configured to be movable longitudinally in the sheath main unit along the longitudinal central axis, independently of movement of the blood vessel cutter so that the blood vessel holding portion moves between a forward position in front of the blood vessel cutting section and a backward position behind the blood vessel cutting section, wherein the blood vessel cutting section and the blood vessel holding portion are substantially symmetrically longitudinally positioned on opposite sides of the longitudinal central axis of the sheath main unit and are movable relative to each other without mutual contact.
