摘要：
A surgical stapling device (10) comprising: an elongated body portion (14) 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 (226), the stop assembly being movably mounted with respect to the cartridge assembly between open and closed positions； characterized by a flexible drive assembly (536) having a distal end configured to move through the cartridge assembly to eject the clips therefrom； and an ejection plate assembly (606) located adjacent to the pivot axis on at least one side of the flexible drive assembly； wherein the ejection plate assembly (606) has a first end (620) fixedly attached to the tool assembly and a second end (618) fixedly attached to the elongated body portion, the plate assembly being placed ejection (606) adjacent to the drive assembly to prevent buckling out of the drive assembly； wherein the ejection plate assembly (606) includes a flexible body (610) having an intermediate spring portion (644) that allows the flexible body to flex outwardly from the longitudinal axis in order to prevent the assembly of the assembly from flexible drive； and wherein the ejection plate assembly (606) further includes a limit element (612) located around an 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 (14) 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 sustancialmente perpendicular al eje longitudinal de la porción de cuerpo alargado, incluyendo el conjunto de herramienta un conjunto de top
