초록 ▼

A tubular anvil sleeve is defined by at least two sleeve portions pivoted to each other for movement about an axis radially outwardly offset from an axis of the tubular anvil sleeve in its closed position. A tubular graft is inserted into the tubular anvil sleeve and a projecting end portion of the graft is folded over an exterior of the tubular annular sleeve. The tubular annular sleeve and the overfolded portion of the graft is inserted into an excised end of a blood vessel after which staples are ejected in a conventional manner. The tubular annular sleeve is removed by axial motion followed by relatively pivoting the sleeve portions about the pivot axis of the sleeve portions to open the tubular annular sleeve and effect the withdrawal/removal thereof.

1. An anvil for use with a stapler operative for stapling end portions of tubes to each other comprising a substantially tubular anvil sleeve having an exterior surface, said exterior surface including means against which staples are driven and closed, said tubular anvil sleeve including at least two sleeve portions, and means for pivotally connecting said sleeve portions for pivotal movement from a first closed tubular stapling position to a second open removal position by relative pivoting movement about a pivot axis substantially parallel to and radially outwardly offset from an axis defined by said sleeve in said closed position whereby subsequent to the performance of a stapling operation said anvil sleeve can be removed from exterior surrounding relationship to a stapled end portion of a tube by pivoting said sleeve portions about said pivotally connecting means from said first closed tubular stapling position to said second open position. 2. The anvil as defined in claim 1 including a handle connected to one of said sleeve portions. 3. The anvil as defined in claim 1 including a handle connected to only one of said sleeve portions. 4. The anvil as defined in claim 1 including a handle, and means for pivotally connecting said handle to one of said sleeve portions. 5. The anvil as defined in claim 1 including a handle, and means for pivotally connecting said handle to only one of said sleeve portions. 6. The anvil as defined in claim 1 including a handle, and means for pivotally connecting said handle to only one of said sleeve portions for pivoting movement about an axis substantially transverse to said first-mentioned pivot axis. 7. The anvil as defined in claim 1 including a handle, and means for pivotally connecting said handle to only one of said sleeve portions for pivoting movement about an axis substantially transverse to said first-mentioned pivot axis. 8. The anvil as defined in claim 1 including a handle, and means for pivotally connecting said handle to only one of said sleeve portions for pivoting movement ab out an axis substantially normal to said first-mentioned pivot axis. 9. The anvil as defined in claim 1 including a handle, and means for pivotally connecting said handle to only one of said sleeve portions for pivoting movement about an axis substantially normal to said first-mentioned pivot axis. 10. The anvil as defined in claim 1 wherein said exterior surface includes means for closing staples adapted to be fired from a stapling head. 11. The anvil as defined in claim 1 wherein said exterior surface includes groove means for closing staples adapted to be fired from a stapling head. 12. The anvil as defined in claim 1 wherein said exterior surface includes a plurality of axially spaced circumferential groove means for closing staples adapted to be fired from a stapling head. 13. The anvil as defined in claim 1 wherein said exterior surface includes a plurality of axially spaced endless circumferential groove means for closing staples adapted to be fired from a stapling head.
