摘要：
A surgical stapling device (10) comprising: an elongated body portion (18, 518) defining a longitudinal axis； a tool assembly (20) pivotally supported at the distal end of the elongated body portion (18, 518) about a pivot axis that is substantially perpendicular to the longitudinal axis of the elongated body portion, the tool assembly includes an anvil assembly (24) and a cartridge assembly (22) that houses a plurality of staples (226), the anvil assembly is movably mounted relative to the cartridge assembly between the open and closed positions, the Tool assembly (20) includes a mounting assembly (202) supported at a proximal end thereof, the mounting assembly being pivotally secured to the elongated body portion (18, 518) about said pivot axis； a flexible driver assembly (212, 536) having a distal end (268, 682) configured to translate through the cartridge assembly to eject staples therefrom； first and second support members (255, 606) positioned adjacent to the pivot axis, wherein the first support member is positioned on one side of the flexible drive assembly and the second support member is positioned on the other side of the flexible drive assembly , each support member having a distal end (260a, 616) fixedly attached to the tool assembly and a proximal end (258a, 614) fixedly attached to the elongated body portion, the support members being located adjacent to the drive assembly to prevent outward buckling of the drive assembly, characterized in that: the distal ends (260a, 616) of the support members (255, 606) each comprise a distal retention portion (260b, 620) that is received from fixedly and mates within the mounting assembly (202)； The proximal ends of the support members each comprise a retention portion (258b, 618) configured to be fixedly received and hooked within a respective slot (250a, 252a, 621, 622) in the elongated body portion ( 18, 518)； and the surgical stapling device further comprises a locking member having an H-shaped body having a
