Remanufactured LigaSure Exact Dissector, Without Nano-coating

Do not divide tissue before the seal cycle is complete as this may result in improper sealing.
Do not pull the cutting trigger while the jaws are open as injury to the patient or surgical team may occur.
Conductive fluids (e.g., blood or saline) in direct contact with or in close proximity to the instrument may carry electrical
current or heat, which may cause unintended burns to the patient. Aspirate fluid from around the instrument jaws before
activating the instrument.
Keep the external surface of the instrument jaws away from adjacent tissue while activating the LigaSure system or
unintended injury may result.
During a seal cycle, energy is applied to the tissue between the instrument jaws. This energy may cause water to be converted
into steam. The thermal energy of steam may cause unintended injury to tissues in close proximity to the jaws. Care should be
taken in surgical procedures occurring in confined spaces in anticipation of this possibility.
Use caution when grasping, manipulating, sealing, and dividing large tissue bundles.
Do not attempt to seal or cut over clips or staples as incomplete seals/damage to the cutting blade will occur. Contact between
an active electrode and any metal objects may result in alternate site burns or incomplete seals.
The surfaces of the jaws may remain hot enough to cause burns after the RF current is deactivated.
Inadvertent activation or movement of the activated instrument outside of the field of vision may result in injury to the patient
or surgical team.
Do not activate the LigaSure system in an open-circuit condition. Activate the system only when the instrument is in direct
contact with the target tissue to lessen the possibility of unintended burns.
Do not activate the instrument while instrument jaws are in contact with, or in close proximity to, other instruments including
metal cannulas, as localized burns to the patient or physician may occur.
Eliminate tension on the tissue when sealing and cutting to ensure proper function and reduce bleeding.
Precaution
When intending only to grasp or manipulate tissue, ensure pressure to the ring handles does not cause the second click that
activates energy delivery.
Keep the instrument jaws clean. Build-up of eschar may reduce the seal and/or cutting effectiveness. Wipe jaw surfaces and
edges with a wet gauze pad as needed.
Do not overfill the jaws of the instrument with tissue, as this may reduce device performance.
Hand Activation
Notice
Closing the ring handles to the second click activates or reactivates energy delivery if hand-activation is being used.
1.
Ensure hand-activation is enabled on the appropriate port. Refer to the generator user’s guide if needed.
2.
Grasp the intended vessel and/or tissue in the center of the jaws.
3.
Close the ring handles until you hear or feel two clicks. At the second click, energy is delivered.
A continuous tone sounds to indicate the activation of RF energy. When the activation cycle is complete, a two-pulsed Seal-
Cycle-Complete tone sounds and RF output ceases.
Notice
The surgeon may inspect the seal before cutting the vessel or tissue. After inspecting the seal, the surgeon should create a
second seal adjacent to the first seal before cutting, as described below.
A tone with multiple pulses indicates that the seal cycle was not completed. Refer to the Troubleshooting section for
possible causes and corrective actions. Do not cut tissue until you have verified that there is an adequate seal.
