Abstract
A surgical stapling device that includes an adapter assembly that has a flexible outer tube, and a tool assembly that is supported on the flexible outer tube having an anvil assembly and a shell assembly that supports an annular staple cartridge. The shell assembly includes a mechanism for approximating the anvil assembly with the shell assembly over two clamping stages to minimize forces transferred to the flexible outer tube of the adapter assembly during clamping. The shell assembly also includes a mechanism for minimizing firing forces required to eject staples from the staple cartridge.
