LigaSure in Minimally-invasive Procedures

Warning
For laparoscopic procedures, be alert to these potential hazards:
• Laparoscopic surgery may result in gas embolism due to insufflation of gas in the abdomen.
• The jaw electrode may remain hot enough to cause burns after the electrosurgical current is
deactivated.
• Localized burns to the patient or physician may result from electrical currents carried through
conductive objects (such as cannulas or scopes). Electrical current may be generated in
conductive objects through direct contact with the active electrode, or by the LigaSure
instrument (electrode or cable) being in close proximity to the conductive object.
• Do not use hybrid trocars that have a non-conductive locking anchor placed over a conductive
sleeve. For the operative channel, use all-metal or all-plastic systems. At no time should
electrical energy pass through hybrid systems. Capacitive coupling of RF current may cause
unintended burns.
• When using laparoscopic instrumentation with metal cannulas, the potential exists for
abdominal-wall burns to occur due to direct electrode contact or capacitive coupling of RF
current. This is most likely to occur in instances where the generator is activated for extended
periods at high power levels inducing high-current levels in the cannula.
• Ensure that the insulation of single-use and reusable laparoscopic instrumentation is intact and
uncompromised. Compromised insulation may lead to inadvertent metal-to-metal sparking
and neuromuscular stimulation and/or inadvertent sparking to adjacent tissue.
Covidien recommends against the use of laparoscopic surgery on pregnant patients.
Warning
For laparoscopic procedures, be alert to these potential hazards:
• The external surfaces of the LigaSure instrument jaws may remain hot enough to cause burns
after the RF current is deactivated.
• Inadvertent activation or movement of the activated LigaSure instrument outside of the field
of vision may result in injury to the patient.
• Do not activate the instrument while the 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.
• Do not activate the LigaSure function in an open-circuit condition. Activate the generator only
when the instrument is near or in direct contact with the target tissue to reduce the possibility
of unintended burns.
• Carefully insert and withdraw LigaSure instruments from cannulas to avoid possible damage to
the devices and/or injury to the patient.
