 Output settings

The RFITT modes are available only for selected CELON bipolar applicators, e.g. 

CelonProSleep plus or CelonProBreath.

During activation, the electrosurgical generator provides audible feedback of the coagulation 

status. The frequency of the output tone is proportional to the tissue resistance at any 

particular moment. As the measured tissue resistance increases, the frequency of the output 

tone also increases. This permits audible monitoring of the coagulation status since the 

latter is directly connected with the tissue resistance.

Energy is applied until the tissue resistance exceeds a limit value, i.e. automatic end-

of-procedure detection. Then the power output is automatically stopped (for the modes 

Fine RFITT, Strong RFITT) or reduced to a minimum (Pure RFITT), because the coagulation 

process is completed due to desiccation of the tissue. This is indicated by an intermittent 

audible signal.

Detailed information on output limits and output characteristics are given in the “Appendix A” 

on page 97.

The medical purpose of the mode Strong RFITT+RCAP is to achieve deep tissue 

coagulation without significant tissue desiccation.

Once the tissue resistance increases significantly, which indicates beginning tissue 

desiccation, the electrosurgical generator reduces the power automatically. This enables 

the tissue to rehydrate, resulting in normal electrical resistance of the tissue after a few 

seconds. Detecting this decrease of resistance, the electrosurgical generator automatically 

increases the power again to the preset level and continues the heating process. This cycle 

is repeated until the user stops the activation or until the tissue resistance exceeds a limit 

value. In the latter case, the power output is automatically stopped, which is indicated by an 

intermittent audible signal.

On the Set Screens of RFITT modes an application time counter and an energy counter are 

displayed. The counters indicate previous treatment parameters. During activation of the 

electrosurgical generator these counters are constantly updated.

 - The application time counter shows the total application duration of output power in 

minutes and seconds in the format [00:00].

After 999 minutes and 59 seconds the application time counter starts counting from 0.
