shell is available. Insert a charged power handle into a sterile control shell, following
the instructions in the Assembling The Signia™ Stapler section.
WARNING
Depending upon the potential failure mode, each of the processes described
below may or may not be successful in retracting the knife and opening the
stapling reload. Professional experience should be used to assess patient status
when deciding the best course of action.
PRECAUTION
When dividing major vascular structures, adhere to the basic surgical principles
of proximal and distal control.
I. Powered Opening Approach
PRECAUTION
Care should be taken to support the adapter during disassembly to prevent
tissue damage.
1. Remove the stapling handle from the adapter by pressing the QUICK RELEASE
button on the top of the adapter while simultaneously pulling the stapling handle off
of the adapter.
2. Reattach the stapling handle onto the adapter and connected reload. Upon
connection to the adapter, 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.
3. Once the stapling reload is disengaged from tissue, remove the power stapling
handle from the patient and inspect the staple line and surrounding tissue for
hemostasis and/or leakage.
If the powered opening approach is unsuccessful, attempt a reboot and follow the
reattachment steps (2-3) as indicated above.
