The surgical stapling device (10) includes a housing (20), an outer tube (60) extending distally from the housing, a disposable staple assembly (300) releasably supported on a distal end of the outer tube, an approximation assembly (100) operably received within the housing, and a staple pusher assembly (200) extending from within the housing to the distal end of the outer tube. The outer tube includes a proximal end configured for operable connection with the housing and a distal end. The staple assembly includes a shell (302) supporting a pusher back (310), and a plurality of fasteners S. The pusher back being axially movable within the shell to eject the plurality of fasteners from the disposable staple assembly, the shell being adapted to be rotabably connected to the outer tube. The approximation assembly includes an anvil retainer (140) releasably engageable with an anvil assembly (80). The approximation assembly being operable to approximate the anvil assembly and the staple assembly. The staple pusher assembly adapted to be rotatably connected to the pusher back of the disposable staple assembly and operable to effect axial movement of the pusher back within the shell. The approximation assembly and the staple pusher assembly are releasably secured within the housing.La présente invention concerne un dispositif dagrafage chirurgical (10) comprenant un boîtier (20), un tube externe (60) sétendant de manière distale à partir du boîtier, un ensemble dagrafes jetable (300) supporté de manière amovible sur une extrémité distale du tube externe, un ensemble de rapprochement (100) reçu de manière fonctionnelle à lintérieur du boîtier, et un ensemble poussoir (200) dagrafes sétendant à partir de lintérieur du boîtier jusquà lextrémité distale du tube externe. Ledit tube externe comprend une extrémité proximale conçue pour un raccordement fonctionnel avec le boîtier et une extrémité distale. Lensemble dagrafes comprend une coque (302) supportant une assise (310) de p
