EnergyShield Monitor Overview
The EnergyShield Monitor provides monitoring of electrosurgical energy during use of
EndoWrist SP monopolar instruments, which are shielded to reduce the risks of capacitive
coupling. The EnergyShield Monitor terminates energy delivery when a fault condition is
detected on the connected monopolar instrument, such as:
• Loss of instrument shield integrity
• Breakdown of internal instrument insulation
• Loss of Instrument Sheath integrity (only in certain conditions)
WARNING: The EnergyShield Monitor will not detect all occurrences of damage to
the monopolar instrument sheath. Inspect the Instrument Sheath for damage
throughout use. Examples of damage include tears or cuts in the sheath material. If
damage is observed, remove and replace the Instrument Sheath on any instrument
(monopolar or other) to prevent stray cautery or other risks.
For more information on troubleshooting the EnergyShield Monitor, see
Connecting the Monopolar Instruments, EnergyShield Monitor
and VIO dV
This section describes how the EnergyShield Monitor works with the da Vinci SP System and
connects to the EndoWrist SP monopolar instruments and the VIO dV.
Note: The EnergyShield Monitor should remain powered on. When the da Vinci SP
System is powered off, the EnergyShield Monitor is in a sleep state with all LEDs off.
The EnergyShield Monitor will start up with the da Vinci SP System when it is
powered on.
Note: The da Vinci SP System should be powered on before the monopolar cord is
connected to the EnergyShield Monitor to enable the EnergyShield Monitor to
complete all self-tests.
1. If not already on, power on the da Vinci SP System. The EnergyShield Monitor performs a
self-test. After the self-test completes, the Instrument LED and Sheath LED illuminate
blue and the Neutral Pad LED and Cord LED illuminate amber (
Figure 8.9 EnergyShield Monitor self test complete
2. Ensure that the VIO dV is plugged into the appropriate power receptacle and powered
on.
