Reprocessed LigaSure Impact™ Curved, Large Jaw, Open Sealer/Dividers
< 2 mm – Confirm that the jaws are in the closed position prior to activating the cutter.
Caution
Energy-based devices, such as ESU pencils or ultrasonic scalpels that are associated with thermal spread should not be used to
transect seals.
Notice – Do not engage the cutting mechanism over sutures, clips, staples, or other metal objects as damage to the cutter may
occur.
1. Prior to cutting the seal, the surgeon can inspect the vessel or tissue to ensure proper sealing: compressed, translucent or
opaque seal with signs of desiccation and visible hemostasis. If not properly sealed, repeat seal cycle, adjusting the
settings if needed.
2. To engage the cutting mechanism, pull the cutting trigger completely back toward the body of the instrument. The
instrument blade transects the seal an average of 2 mm from the distal end of the seal plate.
3. Open the jaws by squeezing the handle until it unlocks, then push the handle completely forward.
Cleaning the Instrument During Use
Warning
Do not activate the instrument or the cutting trigger while cleaning the jaws. Injury to operating room personnel may result.
Important: Keep the instrument jaws clean. Build-up of eschar may reduce sealing and/or cutting effectiveness. Wipe jaw
surfaces and edges with a sterile, water- or saline-soaked gauze pad as needed. Do not clean instrument jaws with a scratch
pad.
Troubleshooting
Alert Situations
•
Note: If both the activation button and footswitch pedal are activated during the same seal cycle, the vessel sealing system
delivers energy from the activation source it detects first.
•
A tone with multiple pulses indicates that the seal cycle was not completed. Do not cut tissue until you have verified that
there is an adequate seal.
•
When an alert condition occurs, energy delivery will be terminated, resulting in an incomplete seal. After the alert
condition has been corrected, the device can be reactivated.
Check Instrument/Seal Cycle Incomplete
A Check Instrument/Seal Cycle Incomplete alert condition produces a sequence of pulsed tones and an alert will be displayed
on the generator. The user should inspect the seal site and instrument before proceeding. If the Check Instrument/Seal Cycle
Incomplete alert appears:
1. Release the footswitch pedal or activation button.
2. Open the instrument jaws and inspect for a successful seal.
3. Follow the suggested corrective actions on the generator screen, the generator quick reference card, or in the generator
user's guide.
4. If possible, reposition the instrument, regrasp tissue in another location, then reactivate the seal cycle.
Regrasp thicker tissue – For thin tissue, open the jaws and confirm that a sufficient amount of tissue is inside the jaws. If
necessary, increase the amount of tissue and repeat the procedure.
