Abstract
A surgical instrument comprising a lockout is disclosed.
Claims19
A stapling assembly for stapling tissue, comprising:
- a staple cartridge, comprising:
- an annular cartridge body;
- staple cavities arranged in annular rows in said cartridge body;
- and
- staples removably stored in said staple cavities;
- a firing drive configured to eject said staples from said staple cavities during a firing stroke of said firing drive;
- an anvil configured to deform said staples;
- a closure drive configured to move said anvil from an open position to a closed position to compress the tissue against said cartridge body during a closure stroke of said closure drive;
- and
- a lockout configured to prevent said firing drive from performing said firing stroke until said closure drive and said anvil have applied a compression force to said cartridge body which exceeds a threshold force.
