EndoShield 2
15 of 44
Technical Specifi cations
Monopolar Operating Mode
The EndoShield 2 detects improper setup conditions and detects operative faults
by providing a monitored pathway for the current which is fl owing from the shield
to the patient return electrode. The fault condition is indicated on the front of the
EndoShield 2 and the fl ow of energy is interrupted from the electrosurgical generator
to the AEM instrument.
Functional Characteristics
Monopolar Setup Fault Detection
If the return electrode is disconnected, or the wrong type of return electrode is
connected, no symbols illuminate on the front of the EndoShield 2.
If an AEM foot-control instrument is not connected to the EndoShield 2, or not
connected properly, the
illuminates RED to identify the setup fault.
Monopolar Operative Fault Detection
If there is excessive shield current or arcing between the shield and the active
electrode causing an operative fault, the
illuminates CONTINUOUS RED for 10
seconds to identify an insulation fault, and the EndoShield 2 interrupts the fl ow of
energy from the electrosurgical generator to the AEM instrument for 10 seconds.
Radio Frequency Current Sensing
Current-sensing and spark detection are provided. Minimum electrosurgical
generator output for reliable insulation fault detection: 20 Watts.
Shield Cable and Return Electrode Switch Threshold
50 ohms ± 40%.
Indicators and Alarm Functions
CONTINUOUS GREEN
Indicates that the EndoShield 2 Burn Protection
System is fully operational.
CONTINUOUS RED
During setup, indicates that the AEM instrument is
not properly connected.
During use, indicates that the instrument in use has
an unsafe operating condition. Indicates that there
is excessive current or arcing between the active
electrode and the shield. Once triggered in this
condition, illuminates RED for 10 seconds.
FLASHING GREEN
Indicates a low battery condition.
FLASHING RED
Indicates a dead battery condition.
