摘要：
A surgical stapling device (10) comprising: an elongated body portion (518) defining a longitudinal axis； a tool assembly (20) pivotally supported at the distal end of the elongate body portion about a pivot axis that is substantially perpendicular to the longitudinal axis of the elongated body portion, the tool assembly including a stop assembly (24) and a cartridge assembly (22) housing a plurality of staples, the stopper assembly being removably mounted with respect to the cartridge assembly between open and closed positions； a flexible drive assembly (536) having a distal end (682) configured to move through the cartridge assembly to eject the clips therefrom； two support elements (606) located adjacent to the pivot axis, in which one support element is placed on one side of the drive assembly and the other support element is placed on the other side of the drive assembly, where each support element has a first end (616) fixedly attached to the tool assembly and a second end (614) fixedly attached to the elongate body portion, where the support elements are each positioned adjacent to the drive assembly to prevent buckling out of the drive assembly； characterized in that the support elements each include a flexible body (610), which includes an axially elongated central portion (644), wherein the flexible body (610) of each support element has an intermediate spring portion ( 644) which allows the flexible body to flex outwardly from the longitudinal axis in order to prevent the union of the flexible drive assembly； and limit elements (612) located around a corresponding intermediate spring portion to limit the extent to which the intermediate spring portion can flex outwards.Un dispositivo de grapado quirúrgico (10) que comprende: una porción de cuerpo alargado (518) que define un eje longitudinal； un conjunto de herramienta (20) apoyado de forma pivotante en el extremo distal de la porción de cuerpo alargado alrededor de un eje de pivotamiento que es sustancia
