More Information
Summary: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 staple firing mode, and a second rotational orientation in which it can actuate a jaw assembly in a reversing mode. The handle assembly can include an articulation mechanism including a ball screw to selectively articulate the jaw assembly relative to an elongate shaft. The handle assembly can include a mechanism to lock out selection of the staple firing mode and actuation of the articulation mechanism if a reload shaft is not securely coupled to the handle assembly.
