DIFFICULTY RETRACTING RELOAD Concern: User is experiencing difficulty retracting a reload off of media. Potential Actions:

6.1. Powered Opening Approach [using the same or a new handle] 6.1.1. Remove the stapling handle from the Signia™ linear adapter by pressing the QUICK RELEASE button on the top of the adapter while simultaneously pulling the stapling handle off of the adapter. 6.1.2. Reattach the stapling handle onto the adapter in use and connected reload. Upon connection to the adapter, the device will recognize if a reload is attached. It will enter a Safe Mode and slowly retract the knife and open the stapling reload, then attempt to zero out the controls forcing the knife to retract and open the stapling reload. 6.1.3. 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.

6.2. If the powered opening approach is unsuccessful, attempt a reboot and follow the reattachment steps 6.1.2 and 6.1.3 as indicated above. 6.2.1. To force a reboot, simultaneously press and hold both SAFETY buttons for ten seconds. 6.2.2. Release the SAFETY buttons. The device will reboot. 6.2.3. 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.

6.3. Using the Manual Retraction Tool 6.3.1. If another power stapler is not available, or the powered opening procedure and the reboot approaches are unsuccessful, use the manual retraction tool procedure 6.3.2. Remove the power stapling handle from the adapter by pressing the QUICK RELEASE button on the adapter while pulling the handle off the adapter. 6.3.3. To control the firing, insert the manual retraction tool into the center hole marked with circle on the proximal end of the adapter. 6.3.4. To continue firing the stapling reload, turn the manual retraction tool counterclockwise, opposite direction of the arrow. 6.3.5. To retract the knife and open the jaws of the stapling reload, turn the manual retraction tool clockwise, the same direction as the arrow. 6.3.6. If the reload is articulated, insert the manual retraction tool into the hole marked with a square on the proximal end of the adapter. If the stapling reload is orientated so that the lower clamp cover is up and the anvil is down, turning the manual retraction tool counterclockwise will articulate the reload to the right. Turning it clockwise will articulate the reload to the left. 6.3.7. Once the reload is centered, remove the instrument from the patient. Refer to the instructions in the Disassembling the stapler section.

Recommended Next Steps:

6.4. If a system stops during retraction and requires any of the above interventions, return the full system [Signia™ power handle, power shell, reload, and Signia™ linear adapter] as a product event.
