Abstract
A surgical stapler is provided that includes a spring loaded lift that automatically adjusts a staple cartridge and/or staple formation between a range of sizes. The lift is automatically released as the staple firing mechanism begins its forward translation of the firing sequence. The automatic one-way adjustment also adjusts the staple cartridge while maintaining the cartridge parallel to the anvil to provide consistent staple formations.
