Method of manufacturing surgical staples
View Patent ↗One exemplary process for manufacturing a surgical apparatus may include providing a flat, generally-planar strip of biocompatible material; cutting the strip to produce a feeder belt with at least one lateral edge, and staples affixed to the feeder belt in proximity to at least one lateral edge, where the staples and feeder belt are substantially aligned along a first plane; and bending at least one staple out of the first plane, while the feeder belt remains in the first plane. Another exemplary process for manufacturing a surgical apparatus may include providing a flat, generally-planar strip of biocompatible material; cutting that strip to produce a feeder belt with edges, and staples affixed to different edges of the feeder belt; and coining at least one staple after the cutting.
1. A process for manufacturing a surgical apparatus, comprising:
separating a feeder belt and a plurality of staples affixed to said feeder belt from a strip of material, said feeder belt and said plurality of staples lay along a first plane; and
bending at least one of said plurality of staples out of said first plane, while said feeder belt remains in said first plane.
2. The process of claim 1 , wherein said separating comprises of cutting, stamping, or coining said strip of material to separate said feeder belt and said plurality of staples from said strip of material.
3. The process of claim 2 , wherein coining is applied only to said plurality of staples.
4. The process of claim 2 , wherein the coining comprises:
inducing plastic flow on a surface of the strip of material.
5. The process of claim 1 , wherein said separating comprises of first cutting and then coining to separate and produce said plurality of staples from said strip of material.
6. The process of claim 1 , wherein said bending operation is performed after said separating operation.
7. The process of claim 1 , wherein said bending causes at least one of said plurality of staples to be bend out of said first plane, while said feeder belt remains in said first plane.
8. The process of claim 7 , wherein the plurality of staples are at about a 90 degree angle to the first plane.
9. The process of claim 1 , wherein separating from said strip of material produces said feeder belt with at least one lateral edge.
10. The process of claim 9 , wherein said plurality of staples being affixed to said feeder belt at or in proximity to said at least one lateral edge of said feeder belt.
11. The process of claim 1 , wherein said plurality of staples affixed to said feeder belt through a narrow strip of material for each of said plurality of staples.
12. The process of claim 11 , wherein said narrow strip of material allows for a frangible connection between each of said plurality of staples affixed to said feeder belt.
13. The process of claim 11 , wherein coining is applied to said narrow strip of material to allow for a frangible connection between each of said plurality of staples affixed to said feeder belt.
14. The process of claim 1 , wherein coining is applied to said plurality of staples for edge hardening of each of said plurality of staples.
15. The process of claim 1 wherein the strip of material is biocompatible.
16. The process of claim 1 , wherein a shape of each of the plurality of staples is homogenous.
17. The process of claim 1 , wherein a shape of each of the plurality of staples is different.
18. The process of claim 1 , wherein the strip includes a plurality of apertures.
19. The process of claim 1 , further comprising:
laser cutting the strip of material.
20. The process of claim 1 , wherein the separating and the bending are performed at different stations of a progressive stamping die.
