Abstract

A surgical system includes an anvil that has, one, an elongate slot extending longitudinally along a length of the anvil and, two, a plurality of first staple-forming pockets. The surgical system further includes an anvil modification member releasably attachable to the anvil, wherein the anvil modification member comprises a plurality of second staple-forming pockets. In addition, the surgical system also includes a staple cartridge that has a plurality of staples formable by the plurality of first staple-forming pockets when the anvil modification member is not attached to the anvil, and wherein the staples are formable by the plurality of second staple-forming pockets when the anvil modification member is attached to the anvil.

Claims

1. A surgical stapler, comprising:

an anvil assembly, comprising;

an anvil, comprising;

an elongate slot extending longitudinally along a length of the anvil;

a first anvil section on a first side of the elongate slot, wherein the first anvil section comprises a plurality of first staple-forming pockets; and

a second anvil section on a second side of the elongate slot, wherein the second anvil section comprises a plurality of second staple-forming pockets;

an anvil modification member attached to the anvil, wherein the anvil modification member comprises;

a first portion positioned against the first anvil section, wherein the first portion comprises a plurality of third staple-forming pockets; and

a second portion positioned against the second anvil section, wherein the second portion comprises a plurality of fourth staple-forming pockets.

2. The surgical stapler of claim 1, wherein the first staple-forming pockets comprise a first pocket arrangement, wherein the third staple-forming pockets comprise a second pocket arrangement different from the first pocket arrangement.

3. The surgical stapler of claim 2, wherein the second staple-forming pockets comprise the first pocket arrangement, wherein the fourth staple-forming pockets comprise the second pocket arrangement.

4. The surgical stapler of claim 1, wherein the anvil modification member further comprises a transectable portion between the first portion and the second portion.

5. The surgical stapler of claim 4, wherein the transectable portion is positioned against the elongate slot.
