INITIAL CHECKS
Initial checks
1. Make sure that the mains power supply corresponds to the technical data (see the data label on the backside of the unit), and connect
the unit with the mains switch (b2-green- on the backside of the unit) off;
2. For a possible equipotential connection, use the plug (b4 on the backside of the unit),
3. Adjust the functioning acoustic signals by the specific rotating control (b6 on the backside of the unit) – the max. is clockwise - . The
alarm signals cannot be regulated.
DATA STORING AT THE SWITCHING ON
When switched on, or after a temporary leak of current:
The unit always stores all the settings/regulations used when switched off (see also Par. “PROGRAMS and MEMORIES”);
The unit does not keep the selection of the bipolar coagulation Micro Auto, and it automatically sets the coagulation Micro
The operators must select the current Micro Auto every time the device is switched on, as the safety rules for the electro-surgical units do
not allow that, when switching on, a current with automatic start/stop system is applied without having been intentionally chosen by
the users.
CONNECTION and USE OF THE FOOT-SWITCH PEDALS
The unit is equipped with a standard twin foot-switch pedal (DS/E), which allows to activate the monopolar currents (cut/coagulating cut or
coagulations) or the bipolar currents (cut/coagulating cut or coagulations).
On request, the unit can also be equipped with another foot-switch pedal (DS/B = twin foot switch pedal to activate cut/coagulating
currents), which allows to activate the bipolar currents only, and therefore it can be very useful in the following cases:
- When surgeons want to continuously alternate the use of monopolar and bipolar currents by simply pressing on the different pedals at
each time (notably in laparoscopic procedures);
- When surgeons want to use the bipolar currents through an independent pedal foot-switch, which is not the one used for the monopolar
currents.
Use of the standard twin pedal foot-switch (DS/E)
Connect the pedal to the socket PED (1) and, by pressing on the key of the area PED- H, select the functioning mode:
- MONO to activate the monopolar currents of cut/coagulating cut (yellow pedal), or coagulation (blue pedal);
- BIP to activate the bipolar currents of cut/coagulating cut (yellow pedal), or coagulation (blue pedal), except for the coagulation Micro
Auto (which is not activated by any pedal foot-switch).
Use of two twin pedal foot-switches (DS/E and DS/B)
Connect the pedal DS/E to the socket PED (1) and the pedal DS/B to the socket PED BIP (2). When the pedal DS/B is connected, the Led of
the area PED – H automatically sets itself on MONO mode, and the unit works as follows:
- The pedal DS/E activates the monopolar currents of cut/coagulating cut (yellow pedal), or coagulation (blue pedal);
- The pedal DS/B activates the bipolar currents of cut/coagulating cut (yellow pedal), or coagulation (blue pedal), except for the
coagulation Micro Auto (which is not activated by any foot-switch pedal).
FUNCTIONING, NUMBER OF USABLE ELECTRODES, and ACTIVATION MODES
1. Monopolar functioning
The monopolar functioning requires the use of two electrodes (an active one, and a neutral one). The current flows from the active
electrode towards the neutral electrode, so that the process concerns all the tissues around the specific point where the active electrode
operates.
For the open sky surgery or the laparoscopy, the unit can be used:
- With 1 or 2 electrodes-holder handle/s (they can be both hand-switch type with twin key cut/coag, or just one can be hand-switch
type with twin key cut/coag, while the other is normal type for use by twin pedal foot-switch cut/coag).
It can be used with two electrodes-holder handles (as above described) at the same time by two different operators. In order
to use the unit in this way, it must be selected a coagulation mode without contact (Fulg – Forced or Spray), as stated by the
International Safety Rules for the HF electro-surgical equipments (IEC 60601-2-2, par. 46.103).
When the unit is on, the bipolar modes are always possible, as specified here below at point 2).
For the flexible endoscopic surgery, the unit can be used:
- With 1 flexible electrode (i.e. loop for polipectomy) by twin pedal foot-switch cut/coag;
When the unit is on, the bipolar modes are always possible, as specified here below at point 2).
For the endoscopic surgery under liquid in urology or gynaecology (TUR), the unit can be used:
- With the monopolar resectoscope by twin pedal foot-switch cut/coag;
When the unit is on, the bipolar modes are always possible, as specified here below at point 2).
2. Bipolar functioning
The bipolar functioning does not require the use of the neutral electrode, as the current flows between the tips of the bipolar electrode,
and it only affects the tissues of this specific area.
The unit always allows this kind of use as follows:
- With 1 bipolar electrode (for cut/coagulating cut and/or coagulation) by twin pedal foot-switch cut/coag;
