Multi-fire lead screw stapling device
First Claim
1. A surgical stapling device comprising;
- a housing;
a plurality of cartridges which are coupled together to form a barrel, the barrel being rotatably supported within the housing, each of the cartridges defining a plurality of staple pockets and supporting a plurality of staples;
an anvil pivotally coupled to the housing, the anvil being movable in relation to the barrel between an open position and a clamped position;
a drive shaft extending through the housing and through the barrel; and
a pusher operatively connected to the drive shaft, the pusher being configured to translate through the barrel and to eject the staples from the plurality of cartridges in response to actuation of the drive shaft;
wherein the barrel is positioned within the housing to align a first one of the plurality of cartridges with the anvil to eject the plurality of staples from the first cartridge upon movement of the pusher through a first firing stroke and subsequently rotatable within the housing to align a second one of the plurality of cartridges with the anvil to eject the plurality of staples from the second cartridge upon movement of the pusher within the barrel through a second firing stroke.

Abstract
A surgical stapling device comprises a housing and a plurality of cartridges that are coupled together to form a barrel that is rotatably supported within the housing. Each of the cartridges defines a plurality of staple pockets that support a plurality of staples. An anvil is pivotally coupled to the housing and is movable in relation to the barrel between an open position and a clamped position. A drive shaft extends through the housing and through the barrel and a pusher operatively connected to the drive shaft. The pusher is configured to translate through the barrel to eject the staples from the plurality of cartridges in response to actuation of the drive shaft. The barrel is positioned within the housing to align a first one of the plurality of cartridges with the anvil to eject the staples from the first cartridge upon movement of the pusher within the barrel through a first firing stroke and subsequently rotatable within the housing to align a second one of the plurality of cartridges with the anvil to eject the staples from the second cartridge upon movement of the pusher within the barrel through a second firing stroke.
