Covidien Signia Stapling System User Manual page 31

NOTE
The stapler will not fire staples or cut tissue until the green LED fire safety
button is pressed.
6. Press and release the SAFETY button on either side of the stapler. An audible
confirmation will occur and the LED indicator will flash green, indicating that the
device is in fire-enabled mode.
7. Press and hold the DOWN/FIRE toggle button until the lower clamp cover reaches
the distal end of the cartridge slot, and the powered handle stops. The firing-progress
indicator will illuminate on the display to show the distance the reload has been fired
(see Table 12).
8. To retract the knife blade after firing, press and release the UP control toggle.
NOTE
If required, firing can be stopped at any time by releasing the DOWN / FIRE
button. To retract the knife before reaching the end of the reload, press and hold
the UP / OPEN button.
9. To open the jaws after firing, press and hold the UP control toggle until fully opened.
WARNING
The stapler can be stopped and opened by pressing the UP toggle button.
However, failure to completely fire the reload will result in an incomplete cut
and/or incomplete staple formation, which may result in poor hemostasis and/
or leakage.
10. Once the device has completed firing and the jaws open, the status indicator
frame and the reload functional status indicator on the display screen will indicate
completed firing status and is no longer able to be fired (see Tables 12-15). Remove
the instrument from the tissue.
