OPERATION OF THE APPARATUS
7.1
DESCRIPTION OF THE APPARATUS
7.1.1
DISPLAY
The CRYO-LINE unit is equipped with an LCD display which displays the most important
operation data of system (Pressure, Temperature, Application time), the alarms and the
data defined by the operator (Application Temperature, Application Time). Using the
two rows of buttons located on the sides of the display, it is possible to activate and
deactivate the functions of the instrument.
7.1.2
SYSTEM STATES
The basic states of the instrument are described below:
•
No Probe: no probe is inserted.
•
Stand by: the probe is inserted, and the system is in an idle state.
•
Freezing: probe tip freezing phase
•
Defrosting: probe tip defrosting phase
•
Venting:
evacuation phase of the residual gas inside the pneumatic
circuit.
•
Purge:
purification phase of particulates and humidity present in the
pneumatic circuit of the probe and instrument.
7.1.3
INITIAL TEST OF THE SYSTEM
In this phase, the CRYO-LINE automatically tests the electrovalves.
7.1.4
STANDARD OPERATION
The standard operation is the basic operation of the instrument. In this state, pressing
the footswitch causes the freezing of the cryosurgical probe. Releasing the footswitch
starts the defrosting state of the probe. Both the time of application as well as the
instantaneous temperature on the tip of the cryoprobe (if equipped with thermocouple)
appear on the display.
7.1.5
TEMPERATURE CONTROL
The use of this procedure is possible only if using cryosurgical probes equipped with a
thermocouple.
