US Patent 12133650 Small diameter surgical stapling device

A surgical stapling device includes an anvil assembly, a staple cartridge, and an outer tube having a proximal body portion and a distal channel portion. A distal end of the proximal body portion defines a pair of cutouts. The anvil assembly includes an anvil body having a pair of pivot members which are supported within the cutouts. The cutouts are dimensioned to allow movement of the pivot members within the cutouts to allow the tissue contact surface of the anvil body to move in relation to the tissue contact surface of the staple cartridge from a “parked position” in which the tissue contact surfaces are in juxtaposed engagement to a “clamped position” in which the tissue contact surfaces defining a tissue gap.
