WARNING: Do not touch the tips while electrosurgical energy is activated as this
may cause severe electrical injury and/or burn to the user.
WARNING: The patient neutral pad must be properly affixed to the patient before
the use of monopolar cautery, to prevent patient or operator injury.
WARNING: Do not bypass the EnergyShield Monitor while using EndoWrist SP
monopolar instruments by connecting the patient neutral pad directly to the ESU.
ESU operation is prevented if the patient neutral pad is not connected to the
EnergyShield Monitor.
WARNING: Aspirate fluid from the area before activating the monopolar instrument.
Conductive fluids (such as blood or saline) in direct contact with or in close
proximity to an active electrode may carry electrical current or heat away from
target tissues, which may cause unintended burns to the patient.
WARNING: Prior to increasing the intensity, check the adherence of the patient
neutral pad and its connections. Apparent low output or failure of the device to
function correctly at the normal operating settings may indicate faulty application
of the patient neutral pad or poor contact in its connections.
WARNING: Loss of safe contact between the patient neutral pad and the patient will
not result in an alarm unless a compatible monitoring patient neutral pad is used.
WARNING: During heavy intraoperative cautery application, it may be possible for
tissue char to cause the blades to stick together or to reduce cutting performance.
Should this occur, remove the instrument and clean the blades with moist gauze or
a scrub pad.
WARNING: While activating monopolar energy, be aware of anatomy that is in
contact with the instrument wrist or shaft. The instrument should not be used as a
retractor while applying energy.
WARNING: Avoid routing the monopolar and bipolar energy cords close together.
Doing so may increase the risk of stray cautery from the bipolar instrument due to
capacitive coupling between the cords.
CAUTION: The EndoWrist SP
monopolar electrosurgical instruments are designed
for use with a maximum peak voltage of 3kV (6kV peak-to-peak). Only compatible
electrosurgical units have been tested to ensure that they do not exceed this limit.
Do not attempt to use instruments with electrosurgical units that are not
compatible with the da Vinci SP System.
