Claim 0:
1. A clinch staple mechanism comprising:
a pivoting base configured to be pivotally connected to a pneumatic stapling tool configured to dispense staples each staple having a crown and a pair of staple legs, wherein the crown is disposed in a crown direction;
a clinch arm pivotally connected to the pivoting base at a proximal end of the clinch arm, wherein the clinch arm further comprises a distal end opposite the proximal end of the clinch arm, wherein a forward direction is defined extending away from the proximal end and towards the distal end, and wherein a rearward direction is defined extending away from the distal end and towards the proximal end; and
a clinch block disposed on the distal end of the clinch arm, wherein the clinch block is configured to bend the pair of staple legs in a direction perpendicular to the crown direction;
wherein the clinch block has a U-shaped curved profile configured to direct the pair of staple legs in the direction perpendicular to the crown direction, wherein the direction perpendicular to the crown is one of the forward direction and the rearward direction;
wherein the clinch block has a bottom portion, a forward curved portion and a rearward curved portion of the U-shaped curved profile, wherein the forward curved portion extends in the forward direction away from the bottom portion, and wherein the rearward curved portion extends in the rearward direction away from the bottom portion; and
wherein the U-shaped curved profile is configured to bend each pair of staple legs following one of the forward curved portion in the forward direction and the rearward curved portion in the rearward direction;
wherein an entire width, in a direction perpendicular to the forward direction or the rearward direction, of the clinch block comprises a U-shaped cross section, and the U-shaped curved profile comprises a pair of parallel staple leg tracks,
wherein the pair of staple leg tracks comprise a pair of parallel grooves formed in a surface of the U-shaped curved profile.
