temperature, the ESU regulates all of the selected electrodes at the
temperature setpoint, turning each off as its temperature rises above the
setpoint and turning it back on as it falls below.
For tissue coagulation, it is recommended that the operator initially select
the lowest possible set temperature. It should be noted that measured
temperature may be slightly lower than maximum tissue temperature.
Measured temperature will be influenced by the degree of tissue contact.
Selecting Temperature Setpoint
The default value for desired tissue temperature (temperature setpoint) is
determined by the probe type of the Electrosurgical Probe connected to
the ESU but can be adjusted by the operator. The ESU then
automatically adjusts power, within the user-selected upper power limit,
to achieve the desired tissue temperature.
To change the temperature setpoint for the ESU, follow these steps:
1. Ensure that the ESU is in STANDBY mode.
2. Press the appropriate TEMPERATURE Button
decrease the temperature setpoint by 1°C. The SET LED is
illuminated to indicate that the value in the TEMPERATURE Display
is the temperature setpoint.
3. To scroll rapidly to the desired temperature setpoint, depress and
hold the appropriate TEMPERATURE Button down.
4. Release the TEMPERATURE Button
TEMPERATURE Display shows the appropriate temperature
setpoint. The MEASURED LED is then illuminated to indicate that the
value in the TEMPERATURE Display is the current value of
measured temperature.
5. The tissue temperature selection range is 50° to 95°C in increments
of 1°C, although the ESU cannot achieve a temperature which is less
than the ambient tissue temperature.
6. During RF DELIVER Mode, the temperature setpoint can be
increased or decreased by pressing the appropriate TEMPERATURE
Button
depressed, the SET LED is illuminated, and the display shows the
new temperature setpoint. When the button is released, the
MEASURED LED is illuminated, and the display shows the present
value of tissue temperature.
About the Audio Control
The user may adjust the volume of the audio signal when the ESU is
initially powered on or during a surgical procedure.
