- a staple fastening assembly (2;
102) in the distal end region of the instrument (1;
100), including a curved cartridge device (10), which comprises at least one curved open row (76, 77, 78) of staples (70) having a concave side and a convex side, and, opposite to the cartridge device (10), a curved anvil (12), which has a staple forming face (80) and is adapted to cooperate with the cartridge device (10) for forming the ends of the staples (70) exiting from the cartridge device (10),a moving device (8, 24, 26, 28, 29, 30, 53, 60) adapted to move the anvil (12) relatively with respect to the cartridge device (10), essentially in parallel relationship, from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue,a staple driving device (9, 32, 34, 36, 37, 38, 57, 64) adapted to drive the staples (70) out of the cartridge device (10) towards the anvil (12),a handle (4;

Abstract
A surgical stapling instrument (1) comprises a staple fastening assembly (2) including a curved cartridge device (10) and a curved anvil (12). The cartridge device (10) comprises at least one curved open row of staples which are formed by a staple forming face of the anvil (12). The anvil (12) can be moved relatively with respect to the cartridge device (10). A handle (4) in the proximal end region of the instrument is operatively connected to the staple fastening assembly (2). A flexible backbone, preferably an endoscope (6), is arranged between the handle (4) and the staple fastening assembly (2) and guides force transmitters (8, 9) of the moving device and the staple driving device.
