摘要：
A surgical stapling device comprises a housing and a plurality of cartridgesthat arecoupled together to form a barrel that is rotatably supported within thehousing. Each of thecartridges defines a plurality of staple pockets that support a plurality ofstaples. An anvilis pivotally coupled to the housing and is movable in relation to the barrelbetween an openposition and a clamped position. A drive shaft extends through the housing andthrough thebarrel and a pusher operatively connected to the drive shaft. The pusher isconfigured totranslate through the barrel to eject the staples from the plurality ofcartridges in response toactuation of the drive shaft. The barrel is positioned within the housing toalign a first one ofthe plurality of cartridges with the anvil to eject the staples from the firstcartridge uponmovement of the pusher within the barrel through a first firing stroke andsubsequentlyrotatable within the housing to align a second one of the plurality ofcartridges with the anvilto eject the staples from the second cartridge upon movement of the pusherwithin the barrelthrough a second firing stroke.
