CHECK OF THE BIPOLAR INSTRUMENT BEFORE THE USE
Set a coagulation current (20/30)
Wet a gauze with physiological solution, and hold it without touching the wet part.
Touch the wet gauze with both ends of the instrument and activate the delivery. The smoke produced
signals the good functioning, otherwise check the connecting cable, the connections among different
parts of the instrument and the insulation of the ends For example the damage of the insulation of
bipolar scissors causes a short circuit which does not allow the current to reach tissues).
GENERAL TECHNICAL FEATURES
The unit includes a computerized system to automatically control the functioning
It performs a main self
‐
check at the switching ON (It repeats it automatically every about 30 minutes).
It stops the power delivery in case of both breakages and mistakes of use by informing users with
acoustic and visual signals (ERROR CODES).
It stores the detected problems to help the following technical assistance.
The unit includes with a computerized self
‐
control and self
‐
adjustment of currents with
PER (Power Efficiency Rating > 98%)
It automatically controls all currents according to the features of tissues with two different systems:
ADC System
– Self adjusting with constant power
APC System
‐
Self adjusting with constant voltage
It also checks that the power delivery corresponds to intended setting and, in case of hardware or
software breakages which could cause an anomalous delivery, it blocks the delivery.
The unit allows the memorization of 99 programs
The programs can be also identified by a text (Name of users or kind of use).
All the setting of a program can be changed whenever users like
The unit includes some programs with a specific pre
‐
setting to facilitate the use.
The unit has 15 programs for the only bipolar use without the neutral electrode.
The unit is usable by one or two monopolar handles or instruments / the unit is always usable by one or
two bipolar instruments
The bipolar instruments are normally usable by foot
‐
switch, but the unit also includes some currents with
automatic “impedance sensing” start/stop systems.
The unit is usable by one or two twin foot
‐
switches
By the standard 34-9333 twin foot
‐
switch which is provided with a foot controlled selector to activate
either the monopolar currents or the bipolar currents.
By the bigger version of the previous model (34-9332 code) which is very useful for the endoscopy.
By an independent twin foot
‐
switch (34-9331) which activates the bipolar currents only.
By both foot
‐
switches (34-9331 and 34-9333).
By the 34-9333 twin foot
‐
switch to activate both the monopolar currents for cut and the bipolar currents
for coagulation or vessel sealing.
The unit has a control circuit of the neutral electrode which allows the users the following
The use either with normal electrodes for adults or with small electrodes for paediatrics or new born.
The use with neutral electrodes either “Single section
‐
Non Split” or “Double section
‐
Split”.
The use of connecting cables with different connectors: European standard and USA standard.
The unit includes the STANDBY mode
It allows the disconnection of the neutral electrode without the intervention of the related control circuit.
The unit includes with the function of self
‐
reset
It, at the switching on, resets all the setting used at the switching on.
The unit includes an automatic circuit to control the HF leakage currents to earth
CURRENTS AND RELATED FEATURES
All the monopolar and bipolar currents are automatically controlled, in real time, by microprocessors according to
the features “impedances / resistances” of tissues. The self
‐
control is different according to the operative need of
the currents:
