Stapler cartridge with staples frangibly affixed thereto
View Patent ↗A surgical apparatus may include a cartridge, and surgical staples affixed to and frangibly separable from that cartridge. A method for surgical stapling utilizing that apparatus may include providing at least one wedge; and moving at least one wedge into the cartridge, where that moving deforms and then shears from the cartridge at least one staple. A method of manufacturing an apparatus for use with a surgical stapler may include fabricating a cartridge configured to be received by the surgical stapler; fabricating staples; and fixing the staples to the cartridge.
1. A surgical apparatus, comprising:
a cartridge, comprising;
at least one longitudinally-extending rail;
an upper surface vertically spaced apart from said at least one rail; and
multiple pins extending from said rail to said upper surface;
multiple stems fixed to said cartridge rail and extending to said upper surface, wherein each of at least some of said stems includes an aperture extending from said rail to said upper surface, and wherein each of said pins extends through one of said apertures; and
multiple surgical staples, each of said surgical staples comprising a single tine with a first end directly and frangibly affixed to only one of said stems and a second end that is free.
2. The surgical apparatus of claim 1 , wherein each of said stems is substantially perpendicular to each of said tines.
3. The surgical apparatus of claim 1 , wherein at least some of said stems are affixed to said upper surface and said rail.
4. The surgical apparatus of claim 1 , wherein at least some of said stems are welded to at least one of said rails and also to said upper surface.
5. The surgical apparatus of claim 1 , wherein at least one stem is fixed to a plurality of said staples.
6. The surgical apparatus of claim 1 , wherein said upper surface further comprises a plurality of openings, wherein each said staple is affixed to said upper surface via one of said stems adjacent one of said openings.
7. The surgical apparatus of claim 6 , wherein said stems are integral with said upper surface of said cartridge.
8. The surgical apparatus of claim 1 , further comprising at least one wedge movable into said cartridge to deform and then shear at least one staple from said cartridge.
9. The surgical apparatus of claim 1 , wherein each of said first ends of said tines is fixed to a first end of one of said pins.
10. The surgical apparatus of claim 9 , wherein a second end of each of said pins is fixed to the upper surface.
11. The surgical apparatus of claim 1 , wherein a first end of each of said pins is fixed to one of said rails, wherein a second end of each of said pins is fixed to the upper surface, and wherein at least some of the stems are affixed between one of said rails and said upper surface by one of the pins.
