ABSTRACT:
A surgical stapling instrument is provided having safety and sequencing features to mandate proper operation of the instrument during surgical clamping and stapling of tissue. The instrument is powered by pressurized gas, and includes a manual control for supplying gas to a clamping mechanism in the stapler head and a trigger for actuating a stapling mechanism therein. The instrument prevents actuation of the trigger until the tissue has been clamped. The trigger may not be actuated to implant staples until a trigger safety has been actuated. Following actuation of the stapling mechanism, the instrument is either automatically reset to its initial condition, or may require manual control by the user to restore the clamping and stapling mechanisms to their initial conditions. The instrument affords correct sequencing of operation and prevents inadvertent stapling.
