A surgical stapler has a handle assembly including a stationary handle and a trigger. The stapler also has a drive assembly with a body having a working end and a cam member supported on the working end. The cam member is positioned to translate relative to the anvil to maintain the anvil in the closed position during firing of the stapler. The trigger is operatively connected to a power cell. The power cell is operably connected to a motor of the drive assembly. The manipulation of the trigger actuates the power cell such that the power cell powers the drive assembly to effect translation of the cam member relative to the anvil. The stapler also has a channel for supporting the staple cartridge and the motor of the drive assembly controls the actuation sled supported within the cartridge. The actuation sled urges the plurality of staples from the cartridge when the anvil is in the closed position and in cooperative alignment with the staple cartridge.
Agrafeuse chirurgicale à poignée stationnaire comprenant cette poignée et un déclencheur, et aussi un ensemble d'entraînement à corps doté d'une extrémité de travail et d'une came sur ladite extrémité. La came a une position qui permet une translation par rapport à l'enclume pour maintenir celle-ci en position fermée durant l'agrafage. Le déclencheur est relié opérationnel à une cellule d'alimentation, qui est reliée opérationnelle au moteur de l'ensemble d'entraînement. Le déclencheur actionne la cellule qui alimente ledit ensemble pour la translation de la came par rapport à l'enclume. Il existe aussi un canal soutenant la cartouche d'agrafes et le moteur contrôle le chariot d'activation soutenu dans la cartouche. Ce chariot pousse les agrafes depuis la cartouche lorsque l'enclume est en position fermée et en alignement coopératif avec la cartcouhe.
