Covidien Signia Stapling System User Manual page 30

Instructions for Use
4. Clamp the tissue to be transected within the jaws of the reload. Use the UP and
DOWN toggle buttons to use the instrument as a grasper to manipulate tissue.
WARNING
When positioning the stapler on the application site, ensure that no
obstructions (such as clips) are within the instrument's jaws. Firing over an
obstruction may result in incomplete cutting action and/or improperly formed
staples.
PRECAUTION
The instrument will not cut tissue beyond the black cut line indicated on the
single-use reload. More than one application of the stapler may be necessary for
tissue exceeding the length of the reload (30 mm, 45 mm, or 60 mm).
PRECAUTION
Placement of tissue proximal to the tissue stops on the reload may result in
stapler malfunction. Any tissue extending beyond the cut line will not be
transected.
5. Press and hold the DOWN button to close the jaws of the reload across the tissue to
be transected. Confirm the reload is fully closed.
When the jaws of the reload are fully closed, an audible tone is indicated and the
green LED light in the safety button is illuminated.
To optimize stapling performance, the Signia™ stapler uses the force measurements
upon clamp and during firing to control the speed of fire.
NOTE
If the stapler must be repositioned when in fire mode, open the jaws by
pressing the UP control button or press the green LED safety button again.
