The instrument (10) comprises a rod (12) having a circumference sufficient to pass within the tubular tissue structure (20), an anvil (14) mounted on the rod (12), and a generally tubular staple cartridge (26) for containing a plurality of staples (210). The anvil (12) and a generally tubular staple cartridge (26) is sufficient to axially accommodate the tubular tissue structure (20) between the rod (12) and the inner surface of the staple cartridge (26), and sufficient to allow the stable cartridge (26) to be moved axially along the rod (12). The staple delivery end of the staple cartridge (26) is positioned toward the staple deforming means (74) of the anvil (14) and has an outer dimension small enough so that the tubular tissue structure (20) can be everted thereover.

L'instrument (10) comprend une tige (12) présentant une circonférence suffisante pour pénétrer à l'intérieur de la structure de tissu tubulaire (20), une enclume (14) montée sur la tige (12), ainsi qu'une cartouche à agrafes généralement tubulaire (26) contenant une pluralité d'agrafes (210). L'enclume (12) et la cartouche à agrafes généralement tubulaire (26) suffisent à loger dans le sens axial la structure de tissu tubulaire (20) entre la tige (12) et la surface intérieure de la cartouche à agrafes (26), et suffisent à permettre le déplacement de la cartouche à agrafes (26) dans le sens axial le long de la tige (12). L'extrémité délivrant les agrafes de la cartouche (26) est placée en direction du dispositif de déformation (74) des agrafes de l'enclume (14) et présente une dimension extérieure suffisamment faible pour que la structure de tissu tubulaire (20) puisse être retournée au-dessus.
