Abstract

A surgical stapling device comprises an elongated body portion having proximal and distal portions and a head portion positioned adjacent the distal portion of the body portion. The head portion includes a shell assembly and an anvil assembly movable relative to the shell assembly between un-approximated and approximated positions. The anvil assembly includes an anvil head and a center rod extending from the anvil head, the center rod includes a first annular engagement member and a second annular engagement member spaced distally from the first annular engagement member, and a drive screw with proximal and distal ends extending at least partially through the body portion and an anvil retainer with proximal and distal ends, the anvil retainer being operably connected to the drive screw and configured and dimensioned to at least partially receive the center rod, wherein the drive screw moves the anvil assembly between the un-approximated and approximated positions, the first annular engagement member configured to engage the anvil retainer and the second annular member configured to engage the shell assembly.

Claims (13)

1. A surgical stapling device comprising:

an elongated body portion having proximal and distal portions; and a head portion positioned adjacent the distal portion of the body portion, the head portion including a shell assembly and an anvil assembly movable relative to the shell assembly between un-approximated and approximated positions, the anvil assembly including an anvil head and a center rod extending from the anvil head, the center rod including a first annular engagement member and a second annular engagement member spaced distally from the first annular engagement member, and a drive screw with proximal and distal ends extending at least partially through the body portion, and an anvil retainer with proximal and distal ends, the anvil retainer being operably connected to the drive screw and configured and dimensioned to at least partially receive the center rod, wherein the drive screw moves the anvil assembly between the un-approximated and approximated positions, the first annular engagement member configured to engage the anvil retainer and the second annular member configured to engage the shell assembly.
2. The surgical stapling device of claim 1, wherein the anvil retainer is secured to the drive screw via a connector including a central body, a first extension extending proximally from the central body, and a second extension extending distally from the central body.
3. The surgical stapling device of claim 2, wherein the first extension is positioned within the distal end of the drive screw and the second extension is positioned within the proximal end of the anvil retainer.
4. The surgical stapling device of claim 3, wherein the first extension and drive screw include corresponding throughbores configured and dimensioned to receive the first pin and the second extension and the anvil retainer include corresponding throughbores configured and dimensioned to receive a second pin to thereby connect the second extension to the anvil retainer.
5. The surgical stapling device of claim 1, wherein the shell assembly includes a boss and the second annular member engages the boss.
6. The surgical stapling device of claim 1, wherein the second annular member comprises an interference member.
7. The surgical stapling device of claim 6, wherein the shell assembly includes a boss, and the interference member comprises an annular ring, the annular ring engageable with the boss.
8. An anvil assembly comprising an anvil head and a center rod extending from the anvil head, the center rod including a first annular engagement member and a second annular engagement member spaced distally from the first annular engagement member, the first annular engagement member configured to engage an anvil retainer of a surgical stapling device and the second annular member configured to engage a shell assembly of the surgical stapling device.
9. The anvil assembly of claim 8, further comprising a marker on the center rod.
10. The anvil assembly of claim 8, wherein the center rod extends proximally from the anvil head a distance greater than or equal to three inches.
11. The anvil assembly of claim 8, wherein the center rod includes a plurality of splines for alignment of the center rod with a shell assembly of the surgical stapling device, the splines positioned between the first and second annular members.
12. The anvil assembly of claim 8, wherein the second annular member comprises an interference member.
13. The anvil assembly of claim 11, wherein the second annular member engages a boss of the shell assembly.
