Apparatus and method for preserving a tissue margin
A cartridge for a surgical apparatus includes a housing having a slot configured to accommodate a blade. A plurality of fasteners is configured to be deployed by the housing. A first row of the plurality of fasteners is positioned on a first side of the slot and a second row of the plurality of fasteners is positioned on a second side of the slot. The first row of the plurality of fasteners is the nearest row of fasteners to the slot on the first side of the slot that are deployed by the housing, and the first row of the plurality of fasteners is spaced apart from the slot such that an undamaged tissue margin is formed on a section of tissue during operation of the surgical apparatus.

9. The cartridge of claim 1 , wherein the slot, the first row of the plurality of fasteners, and the second row of the plurality of fasteners are generally linear.
10. The cartridge of claim 1 , wherein the housing further includes a plurality of fastener openings, and each of the plurality of fasteners is configured to pass through one of the plurality of fastener openings.
11. The cartridge of claim 1 , wherein the first row of the plurality of fasteners is supported by a first compressive member that is detachable from the housing.
12. The cartridge of claim 11 , wherein the first row of the plurality of fasteners is configured to engage a second compressive member to thereby secure the first compressive member to the second compressive member.
13. A cartridge for a surgical apparatus, comprising:
a housing having a surface including:
a slot configured to accommodate a blade;
an upper surface including a plurality of fastener openings, a first row of the plurality of fastener openings being positioned adjacent to the slot on a first side of the slot, and a second row of the plurality of fastener openings being positioned adjacent to the slot on a second side of the slot;
a plurality of fasteners, each of the fasteners being configured to pass through one of the fastener openings;
wherein a distance between the first row of the plurality of fastener openings and the slot is at least 2 mm; and
wherein the slot is a first slot and the blade is a first blade, the housing further includes a second slot configured to accommodate a second blade, and wherein the second slot is positioned between the first slot and the first row of the plurality of fastener openings.
14. The cartridge of claim 13 , wherein a distance between the second row of the plurality of fastener openings and the first slot is at most 1 mm.
15. A cartridge for a surgical apparatus, comprising:
a housing including a first slot configured to accommodate a first blade and a second slot configured to accommodate a second blade;
