CARTRIDGE BODY DESIGN WITH FORCE REDUCTION BASED ON FIRING COMPLETION

A surgical instrument includes a sled and an end effector. The end effector includes a first jaw, a second jaw movable relative to the first jaw, an anvil, and a cartridge channel. The staple cartridge includes a proximal end, a distal end, a cartridge body, and staples supported in the cartridge body, wherein the sled is movable to deploy the staples from the cartridge body against tissue captured between the staple cartridge and the anvil. The cartridge channel is configured to removably retain the staple cartridge, wherein a load is required to remove the staple cartridge from the cartridge channel, and wherein the sled is configured to reduce the cartridge removal load.
