The left side of the screen displays the Current step (
Freeze
,
Thaw
, or
Extraction
)
and time left for this step.
•
The right side of the screen displays information concerning the overall Protocol,
including total protocol time, time elapsed, protocol format, and changes you
have made, if any, to the preprogrammed protocol.
Thaw
During
Thaw
, the ice ball melts partially or totally depending on the
Thaw
time and the
tissue properties.
Since the
Thaw
step is a primary destructive factor in cryoablation mechanism it is
important to have a
Thaw
step between two
Freeze
steps and to keep the cryoprobe
location steady in the target tissue during all of the
Thaw
period. Monitor the process
under ultrasound or other imaging modality.
Extraction
The
Extraction
step occurs at the end of every treatment. Its purpose is to allow the
cryoprobe
’s
removal from the target tissue in the fastest and safest way.
The
Extraction
step occurs at the end of every treatment, when you use the automatic
mode. Its purpose is to allow the cryoprobe’s removal from the target tissue in the fastest
and safest way.
In order to be able to get the
Extraction
option, the
Freeze
time should have been at least
2 minutes.
If you did not previously freeze for 2 minutes, the system may update you to wait for a
passive thawing process (fig. 85) before you can extract the cryoprobe.
•
To activate the
Extraction
, press on the optional RED button on the straight
cryohandle or the
Extraction
icon on screen as previously shown.
•
The
Extraction
screen will be displayed and a time count will appear.
•
At the end of the
Extraction
step, a message will be displayed on screen informing
the user that the
Extraction
step is done (for example 40-50 seconds for 2 cm ice
ball).
•
Wait for the message, then gently remove the cryoprobe from the target tissue and
then press
Finish
. Do not force removal of the cryoprobe from the tissue as it might
increase the risk of hematoma.
•
If the cryoprobe cannot easily be extracted from the tissue, press the RED HANDLE
button on the straight cryohandle or
Extraction
icon on screen to initiate another
Extraction
step.
•
After the cryoprobe has been removed from the tissue, press the Action button on
the straight
cryohandle or the “Finish” icon on screen to complete the procedure.
