Description of the work of the electrosurgical apparatus.

The principle of operation of the device is based on the use of high-frequency electric current. For electrolysis purposes, only the capacitive component of the high-frequency current is used, and for the purposes of coagulation, the capacitive or resistive component of the high-frequency current is used.

Work in epilation mode.

Connect the handle 7a for epilation (figure 2) to the transformer 5 (figure 1) through the socket 21b. Turn the tip 7b of the handle 7a counterclockwise by 1.5-2 turns, slightly unscrewing it. Insert a tungsten filament (not shown) into the tip 7b of the handle 7a to a depth of about 1 cm. Turn the tip 7b clockwise to secure it. Cut the tungsten filament to the required length at an angle of 45 °, and lightly clean it with a fine sandpaper to remove burrs. After disinfection of the thread (not shown), the tip 7b and the handle 7a, proceed to work.

Work in automatic exposure mode.

To set the automatic mode press the button 24 "FLASH", the indicator 15 will show the last setting. Then using buttons 16a and 16b setting the exposure time select the required exposure time. The exposure time is displayed on the light indicator 15 in conventional units. For the convenience of using the device on the control panel 9 above the indicator 15 there is a table of correspondence of the indicator readings to the exposure time (Fig. 2).

The control step of the automatic exposure time is 0.002 sec, which improves the control accuracy.

The working power of the device is regulated by buttons 14a and 14b and is displayed on the light indicator with 13 digits corresponding to the percentage of the maximum rated power.

To start work, press the button 20 "Start" of the apparatus. A blinking dot will appear in the lower right corner of the treatment time indicator 18. Indicator 18 will show the duration of the procedure (in minutes).

The indicator 17 of the number of impulses will show the number of presses on the pedal 26. If it is necessary to take a break in the work, press the button 21 "Stop". To resume work, press the button 20 "Start".

At the end of the work, press the button 21 "Stop" and record the time of the procedure. Then press the button 19 "Reset". The procedure time indicator 18 and the number of impulses indicator 17 are reset to zero.

Operation in non-automatic exposure mode (OFF).

The mode is set by pressing the buttons 25 "TERM", on the indicator 15 appears the indication "OFF". In this case, the pulse exposure time will be determined by the time you press the pedal 26. The rest of the actions are carried out as in the automatic exposure mode.

Work in coagulation mode.

Connect the coagulation handle 6a to socket 27c. Fix the required electrode (6c-6f) (figa-3d) for coagulation in the collet clamp of the handle 6a. Handle 6a is ready for use. If it is necessary to use a neutral electrode 8, connect it to the socket 27a on the front panel of the apparatus.

When working in coagulation mode, automatic exposure mode is not required. Therefore, it is necessary to switch to the manual exposure mode by pressing the “THERM” button 25. The indicator 15 will show the indication "OFF". To exit the "OFF" (manual exposure) mode, press the "FLASH" button 24.

Sound signal operation.

For ease of use, the exposure can be accompanied by a sound signal. To turn on the sound signal, press the button 22 "ON" on the control panel 9. To turn off the sound signal, press the "OFF" button 23 on the control panel 9.

During continuous operation (30 minutes), the device may heat up. The start of overheating is accompanied by short beeps. It is necessary to turn off the device for 2-3 minutes and start working again. The repetition of short beeps after restarting the device indicates that the device has not cooled down.

Accounting for operating time.

To take into account the time of the procedures, the apparatus is turned off, and then it is turned on while the "Start" button 20 is pressed. Indicators 13 and 15 will display a six-digit number. It shows the total operating time of the device in minutes. Press the button 19. The six-digit number on the indicators 13 and 15 shows the total number of pulses. Turn off the device. Then turn it on as usual. The device is ready for use.
