Abstract

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.

Claims

1. A method of manufacturing a staple cartridge for use with a surgical stapler, comprising:

fabricating an upper surface of the staple cartridge with at least one opening for deployment of at least one staple there-through;

attaching at least one longitudinal-extending rail member within a body of the staple cartridge with a vertical space or gap between a bottom of the upper surface of the staple cartridge and a top of the longitudinal-extending rail member; and

coupling a least one staple along the rail member at a position or location that allows the staple to be deployed through the opening of the upper surface of the staple cartridge.

2. The method of claim 1, wherein the staple is coupled to the top of the longitudinal-extending rail member.

3. The method of claim 1, wherein the staple is coupled to the longitudinal-extending rail member through a stem member or a stem portion of the staple.

4. The method of claim 3, wherein the thickness of the stem member or the stem portion of the staple is the same or less than the vertical space or gap between the bottom of the upper surface of the staple cartridge and the top of the longitudinal-extending rail member.

5. The method of claim 3 further comprising pinning the stem member or the stem portion of the staple to the rail member.

6. A method of manufacturing a staple cartridge for use with a surgical stapler, comprising:

fabricating an upper surface of the staple cartridge with at least one opening for deployment of at least one staple there-through;

coupling a least one staple along a bottom of the upper surface of the staple cartridge at a position or location that allows the staple to be deployed through the opening of the upper surface of the staple cartridge.

7. The method of claim 6, wherein the staple is coupled to the bottom of the upper surface of the staple cartridge through a stem member or a stem portion of the staple.
