    摘要: Jaw assemblies for a surgical stapler are provided. The jaw assemblies comprise a first jaw having a first clamping surface and a plurality of staples disposed therein and second jaw assembly having a second clamping surface. The jaw assemblies can be actuated from a closed configuration in which the first clamping surface contacts or is adjacent to the second clamping surface to an open configuration in which the second jaw is pivoted away from the first jaw to a stapling position in which the second clamping surface is parallel to the first clamping surface and spaced apart from the first clamping surface. A pivoting link or sliding pivot joint can couple the second jaw to the first jaw to facilitate motion between the closed position, the open position, and the stapling position.

    摘要: A handle assembly for a surgical stapler can comprise a rotatable actuation shaft. The actuation shaft can have a first rotational orientation in which it can actuate a jaw assembly in a repeatable open and close mode, a second rotational orientation in which it can actuate a jaw assembly in a staple firing mode, and a third rotational orientation in which it can actuate a jaw assembly in a reversing mode. The handle assembly can include a rotational mechanism arranged to discretely position the rotatable actuation shaft in one of the rotational orientations. The rotational mechanism can be arranged for single handed operation such as by including a slidable switch or selector to rotate the actuation shaft.
