II. Rebooting the power handle
Another way to open the stapling reload is to reboot the power handle.
During a reboot, the device will run through a calibration process and recognize if a
reload is attached. It will then attempt to zero out the controls, forcing the knife to
retract and open the stapling reload. A reboot can be performed while attached to the
adapter and stapling reload or separately.
PRECAUTION
Rebooting the power handle during a firing or incomplete firing will stop the
firing process, retract the knife blade, and open the jaws of the stapling reload.
1. To force a reboot, simultaneously press and hold both SAFETY buttons for ten seconds.
2. Release the SAFETY buttons. The device will reboot.
3. Once the stapling reload is disengaged from tissue, remove the stapler from the
patient and inspect the staple line and surrounding tissue hemostasis and/or leakage.
III. Using the Manual Retraction Tool
If another power stapler is not available, or the powered opening procedure and the
reboot approaches are unsuccessful, use the manual retraction tool procedure.
WARNING
The manual retraction tool is intended to be used as a back-up device for the
stapler should the stapler experience a failure during operation. It can be used
to complete a firing that has already been initiated, or to retract the knife and
open the jaws to remove a reload from tissue. It should NOT be used to initiate a
new firing of a stapling reload.
PRECAUTION
The manual retraction tool can only be used as a backup for the stapling handle.
Should a failure occur in either the stapling reload or adapter, the stapling
reload may not respond to inputs from the manual retraction tool.
