BIPOLAR MODE
INTRODUCTION
As far as the bipolar functions, please note as follows:
- They are always available, as alternative to all the other monopolar functioning modes;
- They can be used alone, without connecting the neutral electrode. See the pre-set programs in next paragraph;
- Besides the standard twin pedal foot-switch (DS/E, for the monopolar or bipolar use), the unit can also be equipped or with another
pedal (DS/B= twin pedal for bipolar cutting/coagulating functions), on request. (See Par. “CONNECTION and USE of the PEDAL
FOOT-SWITCHES”);
- The unit is equipped with a coagulating current Micro Auto (impedance sensing type) with automatic start/stop system (switching on
with adjustable delay from 0.5 to 5sec, by the control device b5 which is placed on the backside of the unit, when the tips of the forceps
get in touch with the non coagulated tissues – switching off when the tissues are coagulated). This system does not require any pedal
foot-switch;
-
CONNECTION and USE of the ACCESSORIES
The unit is equipped with one socket for the connection of the bipolar electrodes.
1. Socket 8-BIP: bipolar electrode (connected cable without any particular polarity) for use by foot-switch pedal
for cutting and/or
coagulation. The foot-switch pedal for the Micro auto coagulation with automatic start/stop system is not used;
der to facilitate the bipolar use, the unit is equipped with 1 pre-set program (See Par. “PROGRAMS and MEMORIES”, program nr.8)
which is characterised by what follows:
- Disconnection of the neutral electrode safety circuit, which is not required for the bipolar use only (as a matter of fact, through the 3 lit
alarm Led, the circuit just informs the operators that the neutral electrode is not connected);
- Impossibility to use the monopolar currents (the displays for the monopolar currents powers are switched off).
Just in case of cables with connection plugs which are different from ALSA standard type, ask for:
- ALSA cables, by specifying the model and the instrument connector type;
- Adaptor, by specifying the type of the cable plug (i.e. coaxial MARTIN type).
BIPOLAR CURRENTS, ELECTRODES, ADJUSTMENT of the POWERS
CURRENTS for CUT
PURE CUT (PURE) – Cut with minimum coagulating effect
This current is controlled by an automatic system (ADC System) for the self regulation of the functioning, which guarantees that the power
selected by the operators remains constant according to the characteristics of the tissues.
Control devices to be used (area L):
- With the selection key, select the current PURE, then adjust the power with the regulation keys;
- For the delivery (loud acoustic signal, and yellow Led), press on the yellow pedal of the twin foot-switch pedal.
Instructions for use, adjustments, and electrodes
Use the specific electrodes, from:
40-50W, with cutting electrodes, needle type;
90-100W, with the bipolar loop electrodes of the bipolar resectoscope, for soft tissues (i.e. into the bladder);
100-110W, with the bipolar loop electrodes of the bipolar resectoscope (i.e. for TUR).
COAGULATING CUT (BLEND) – Cut with coagulating effect
This current is controlled by an automatic system (ADC System) for the self regulation of the functioning, which guarantees that the power
selected by the operators remains constant according to the characteristics of the tissues.
Control devices to be used (area L):
- With the selection key, select the current BLEND, then adjust the power with the regulation keys;
- For the delivery (loud acoustic signal, and yellow Led), press on the yellow pedal of the twin foot-switch pedal.
Instructions for use, adjustments, and electrodes
As per the current PURE
CURRENTS for COAGULATION
“MICRO” COAGULATION (MICRO) – Very soft coagulating effect
This is a constant voltage current and it is controlled by a special automatic power self adjustment system (ADC System)
according to the characteristics of the tissues.
It is the most suitable current when operating on extremely delicate tissues.
Control devices to be used (area F):
- With the selection key, select the current MICRO, then adjust the power with the regulation keys;
- For the delivery (acute acoustic signal, and blue Led), press on the blue pedal of the twin foot-switch pedal or the single foot switch
pedal.
Instructions for use, adjustments, and electrodes
Use coagulation forceps with tips of: 0.5mm (from 0.5-1W), 1mm (from 1-2W), and 2mm (from 2-4W);
Use coagulation forceps for laparoscopy, from 20-30W.
Instructions for use, adjustments, and electrodes
Use coagulation forceps with tips of: 0.5mm (from 0.5-1W), 1mm (from 1-2W), and 2mm (from 2-4W);
Use coagulation forceps for laparoscopy, from 10-20W;
Use the bipolar electrodes of the bipolar resectoscope, from 50-60W.
“MICRO AUTO” COAGULATION (MICRO AUTO) – Very soft coagulating effect and automatic start/stop system (impedance
sensing type)
This current is the same as the MICRO current, as far as the performances and the indications are concerned.
