Reprocessed LigaSure Impact™ Curved, Large Jaw, Open Sealer/Dividers
•
The jaws may remain hot enough to cause burns after the RF current is deactivated. When not using instruments, place
them in a clean, dry, highly visible area not in contact with the patient. Inadvertent contact with the patient may result in
burns.
•
Place the vessel or tissue in the center of the jaws. To avoid incomplete sealing, do not grasp tissue beyond the electrode
surface; do not place tissue in the jaw hinge.
•
Contact between an active instrument electrode and any metal object (hemostats, staples, clips, retractors, etc.) may
increase current flow and can result in unintended surgical effects, such as an effect at an unintended site or insufficient
energy disposition.
•
Conductive fluids (e.g., blood or saline) in direct contact with or in close proximity to the instrument may carry electrical
current or heat. This may cause unintended burns to the patient. Remove fluid from around the instrument jaws before
activation of the instrument.
•
Always keep the external surface of the instrument jaws away from adjacent tissue while activating the instrument.
•
During a seal cycle, energy is applied to the area between the instrument jaws. This energy may cause fluid to be
converted into steam. The thermal energy of steam may cause unintended injury in close proximity to the jaws. Care
should be taken in surgical procedures occurring in confined spaces in anticipation of this possibility.
•
Do not activate RF energy until the handle has been properly latched. Activating the device before this is done may result
in improper sealing and may increase thermal spread to tissue outside the surgical site.
• Do not activate the instrument while in contact with or near other instruments, including cannulas. Localized burns to the
patient or physician may occur.
•
Keep the cord free from the jaw and latch area of the instrument.
•
Eliminate tension on the tissue while sealing and cutting to ensure proper function.
•
Do not attempt to seal over clips or staples as this may result in an incomplete seal.
•
If the seal-cycle complete tone has not sounded, an optimal seal may not have been reached. Reactivate the RF energy
until a seal-complete tone is heard.
Caution
•
Pediatric applications and/or procedures performed on small anatomic structures may require reduced power settings.
The higher the current flow and the longer the current is applied, the greater the possibility of unintended thermal
damage to tissue, especially during use on small appendages.
•
Activate the instrument ONLY when ready to deliver electrosurgical current and when the active tip is in view.
Tissue Manipulation and Dissection
•
The instrument can be used to manipulate and dissect tissue with the jaws either open or closed.
Rotating the Instrument Jaws
•
Notice – Do not turn the rotation wheel when the handle is latched. Product damage may occur.
•
Turn the gray rotation wheel on the handpiece to adjust the jaw position as needed.
Sealing Vessels and Tissue Bundles
1. Open the jaws by pushing forward the white, movable handle.
2. Grasp the intended vessel and/or tissue in the center of the jaws.
3. Close the handle until it clicks and latches in place.
4. Activate the instrument by either of the following methods:
•
Press and hold the purple activation button on the back of the instrument.
•
By using an appropriate footswitch associated with the generator.
Refer to the generator user's guide for footswitch instructions.
A continuous tone sounds to indicate that the vessel or tissue is being sealed. When the activation cycle is complete, a
double end tone sounds and the energy platform discontinues RF output.
5. Release the purple activation button on the instrument, or the footswitch pedal when the seal cycle is complete.
6. To seal adjacent tissue, overlap the edge of the existing seal. The second seal should be distal to the first seal to increase
seal margin. Failure to overlap seals when a second seal is desired may compromise seal integrity.
Cutting Tissue
Warning
Do not overfill the jaws of the instrument with tissue. This may damage the cutting mechanism or cause the blade to deploy
outside of its guiding features, possibly resulting in difficultly opening the jaws or unintended injury to the user or patient.
