PCT No. PCT/SE93/00286 Sec. 371 Date Dec. 28, 1994 Sec. 102(e) Date Dec. 28, 1994 PCT Filed Apr. 5, 1993 PCT Pub. No. WO94/00277 PCT Pub. Date Jan. 6, 1994.A stapler for driving staples (2) into an object (3) has a drive element (1) for pushing a U-shaped staple (2) out of a magazine (10) to drive its legs (2a) through the object. The stapler also has an anvil device (11) comprising two anvil members (4) which are substantially symmetrically arranged with respect to the staple (2) driven into the object, and which are each pivotable about an axis (5) substantially perpendicular to the plane of the staple, the anvil members (4) being pivotable between a starting position, in which they are so positioned that the free leg ends of the staple (2) will engage the respective anvil member when the staple is driven into the object, and an end position, in order, when pivoting from the starting position to the end position, to bend the projecting end portions of the staple legs (2a) driven through the object (3), against the object in a direction towards each other. The axis (5) of each anvil member ( 4) is so located that the anvil member, when pivoting from the starting position to the end position, is swung towards the other anvil member at the side of the anvil axis (5) facing the staple (2).
