Staple trap for surgical stapler

1. A surgical stapler, comprising:

a staple holder including

a cavity defined therein,

a plurality of staples held within said cavity;

an upper surface;

a plurality of apertures defined through said upper surface through which said staples are deployable,

at least one wedge movable within said cavity, and

at least one staple trap including a strip and a plurality of arms extending from and bent relative to said strip, wherein at least one said arm resides in a neutral position directly underneath a corresponding said aperture such that said at least one arm blocks at least one of said staples from moving through said corresponding aperture, and wherein articulation of said wedge moves said at least one arm away from the neutral position to allow for release of said at least one staple.

2. The surgical apparatus of claim 1 , wherein at least one said strip is oriented substantially longitudinally within said staple holder.

3. The surgical apparatus of claim 1 , wherein at least one said strip is oriented substantially parallel to the direction at least one corresponding said wedge slides within said cavity.

4. The surgical apparatus of claim 1 , wherein at least one said arm is generally rectangular.

5. The surgical apparatus of claim 1 , wherein at least one said arm is generally trapezoidal.

6. The surgical apparatus of claim 1 , wherein at least one said arm generally forms a parallelogram.

7. The surgical apparatus of claim 1 , wherein at least one said wedge is an active wedge.

8. The surgical apparatus of claim 1 , wherein said wedge deflects said arms laterally away from the neutral position as it slides within said cavity, wherein said deflection sequentially moves said arms laterally away from the neutral position to a position no longer directly underneath a corresponding said aperture.

9. The surgical apparatus of claim 8 , wherein continued motion of said wedge sequentially allows said arms to return to their neutral position.

10. The surgical stapler of claim 1 , further comprising an end effector, wherein said staple holder is a cartridge detachable from said end effector.

11. The surgical stapler of claim 1 , further comprising an end effector, wherein said staple holder is fixed to and nondetachable from said end effector.

12. The surgical stapler of claim 1 , wherein said wedge is movable by sliding substantially longitudinally.

13. A surgical stapler, comprising:

a staple holder including

a cavity defined therein,

a feeder belt extending into said cavity,

a plurality of staples within said cavity, said staples affixed to and frangibly separable from said feeder belt,

an upper surface;

a plurality of apertures defined through said upper surface through which said staples are deployable,

at least one wedge longitudinally movable within said cavity, and

at least one staple trap including a strip and a plurality of arms extending from and bent relative to said strip, wherein at least one said arm resides in a neutral position directly underneath a corresponding said aperture such that said at least one arm blocks at least one of said staples from moving through said corresponding aperture, and wherein articulation of said wedge moves said at least one arm away from the neutral position to allow for release of said at least one staple.

14. The surgical apparatus of claim 13 , wherein at least one said wedge is an active wedge.

15. The surgical apparatus of claim 13 , wherein a plurality of said staples are arranged in a longitudinal row along a corresponding said feeder belt, wherein said wedge is longitudinally moveable to sequentially both deflect said arms laterally and deploy said staples.

16. The surgical apparatus of claim 15 , wherein said wedge is longitudinally movable in a distal direction from an initial location.

17. The surgical apparatus of claim 13 , wherein said arms are leaf springs.
