Abstract

The present invention provides a surgical stapling device (stapler). The stapler includes a housing, an elongated member, and a reloader. The staple cartridge is configured to be selectively connected to the first jaw member of the reloader and includes one or more resilient members on the staple cartridge. An anvil operatively supported on the second jaw member of the reloader is configured to compress one or more fasteners ejected from the staple cartridge. The anvil includes one or more locking members thereon. The cutter is configured to translate through the staple cartridge and anvil when the first and second jaw members are in a closed configuration. Engagement between the cutter and the resilient member causes the resilient member to move from an initial configuration that allows the cutter to move distally past the locking member to a final configuration that allows the locking member to engage the cutter.
