THE ELECTROSURGICAL UNITS EXCELL NHP
Thanks to the possibilities offered by the most recent micro-
processors, the new models Excell NHP have been designed
according to a "manufacturing philosophy" which privileges
the easy and immediate comprehension of all the
usage/regulation modes, and at the same time guarantees a
wide range of performances, an absolute reproducibility and
functioning personalization, as well as a maximum safety and
reliability. The series is composed of three models for electro-
surgery: Excell NHP-400/D , Excell NHP-350/D , and Excell
NHP-250/D , which can all be connected to an independent
Argon gas module; there are also two models for electro-
surgery and electro-surgery with Argon gas: Excell NHP-
400/DA and Excell NHP-250/DA .
100 FUNCTION MEMORIES
In order to help the operators and assure the perfect
personalization of the performances, the models Excell NHP
allow memorizing and then selecting through a simple button
100 complete functioning programs, which include pre-set
programs for the general or the laparoscopic surgery, the
endoscopic surgery under liquid, the flexible endoscopic
surgery, as well as the simple bipolar mode.
For the models equipped with the Argon gas function, there
are also the programs for the usage in general or laparoscopic
surgery, as well as the programs for flexible endoscopy with or
without the Argon gas.
A WIDE RANGE OF CURRENTS TO SATISFY
ALL THE OPERATING NEEDS
The Excell NHP units have got 17 currents: 10 for the
monopolar usage, and 7 for the bipolar usage.
Three for the monopolar cut, with self regulation
ADC System – constant power and Starting impulse control:
• Pure , non modulated sinusoidal current for the cut without
any coagulating effect.
• Blend 1 , modulated and pulsed sinusoidal current for the cut
with normal coagulating effect.
These 2 currents, thanks to specific auto-check software, are
perfect for all kinds of usage: normal or specialist surgery,
laparoscopy, TUR and vaporization, as well as all the
applications under liquid.
• Blend 2 , modulated and pulsed current for the cut with a strong
coagulating effect spray type for surgery or laparoscopy.
Three for the monopolar cut, with self regulation
APC System – constant voltage and Starting impulse control:
• Auto Pure , non modulated sinusoidal current for the cut
without any coagulating effect.
• Auto Blend , modulated and pulsed sinusoidal current for the
cut with normal coagulating effect.
• Auto Endo , current with alternating phases of cut and
coagulation for the flexible endoscopy.
These currents are perfect for the normal surgery, the
laparoscopy and the flexible endoscopy, notably when a very
delicate effect with a minimum superficial necrosis is desired.
Four for the monopolar coagulation with self regulation
ADC System – constant power:
• Fulg Forced, modulated high voltage current with an optimum
superficial and deep efficacy, which is suitable both for the
direct usage with an active small section electrode and for the
indirect usage through an insulated coagulation forcep.
It is perfect also to obtain a cut with a strong coagulating
effect.
• PinPoint-Contact , modulated medium voltage current, which is
very similar to the previous one, but with a more delicate effect.
• Soft, modulated low voltage current with a strong deep
effect, and no superficial carbonization.
It is perfect for the direct usage with coagulation electrodes,
or for the indirect usage through an insulated coagulation
forceps.
• Spray, modulated and pulsed very high voltage current, with
a very strong superficial effect and a low penetration into the
tissues. It is perfect for the direct usage without any contact,
with small section electrodes.
Two for the bipolar cut, with self regulation ADC System –
constant power and Starting impulse control:
• Pure, non modulated pulsed sinusoidal current for the cut.
• Blend , modulated and pulsed sinusoidal current for the cut
with coagulating effect. With laparoscopic forceps, it is also
suitable to obtain a strong coagulating effect only.
Thanks to some specific auto-check software, these currents
are perfect for all kinds of usage: normal or specialist
surgery, laparoscopy, TUR and all other bipolar applications
with saline solution.
Two for the bipolar coagulation, with self regulation
APC System – constant voltage:
• Micro CV, non modulated low voltage current for very delicate
coagulations with Soft / Micro Precise effect, a minimum
superficial carbonization, and no sticking on the tissues.
• Micro Auto , identical to Micro CV , but with Auto Start / Auto
Stop Impedance Sensing and Start Delay adjustable from 0
to 5 sec. It is perfect for the usage with manual activation,
and no need of special forceps with switch device.
Two for the bipolar coagulation, with self regulation
ADC System – constant power:
• Micro HC, current with Standard Forced effect in order to
rapidly coagulate the vascularized points and the bleedings
during the procedures with saline solution, and use
instruments with tips of big dimensions.
• Macro, modulated and pulsed current with a stronger effect
than the Micro HC current.
One for the coagulation / sealing of big vessels, with
self regulation ADC System – constant power:
• Seal HC, pulsed current to coagulate and close the big vessels
with a minimum superficial carbonization and no sticking of the
tissues. It can be activated through a pedal foot-switch, and
thanks to the Auto Stop Impedance Sensing system it is very
efficacious and easy to use, in laparoscopy too.
COMPLETE OUTPUT POWER CONTROL
In order to guarantee the best possible efficiency and the
minimum side effects, all the output currents are completely
self controlled through a micro-processor with three different
systems:
• ADC System – constant power , which automatically adjusts
the powers by verifying the voltage and the current,
according to a continuous feed-back in real time (7,000
checks/sec) between the unit and the patient tissues, as well
as between the electrode and its rapidity of sliding on the
tissues. This system is also necessary to intervene in an
efficacious way on many types of tissue or under liquid with
the lowest possible powers.
• APC System – constant voltage , which automatically
adjusts the powers, by keeping the voltage – and so the
currents electric arc – constant, according to a continuous
feed-back in real time (7,000 checks/sec) between the unit
and the patient tissues, as well as between the electrode and
its rapidity of sliding on the tissues. This system is also
necessary to intervene in an efficacious and very delicate way
on the operating point with the minimum superficial necrosis.
• Starting impulse control , which electronically checks the
starting pulse of the cut currents, in order to guarantee the
maximum efficacy with the lowest possible powers.
ALL POSSIBLE USAGE MODES,
TWO MONOPOLAR OUTPUTS, AND TWO
BIPOLAR OUTPUTS
All models are equipped with: two monopolar outputs, which
can be used at the same time by two different operators
through the Twin activation device; two bipolar outputs, which
are very useful and common today, notably in laparoscopy.
The two monopolar outputs can be activated by three modes:
• Both of them by the hand-switches placed on the electrodes
holder handles, or by the double pedal foot-switch.
• One by the hand-switches placed on the electrodes holder
handle, and the other by the double pedal foot-switch.
For the usage with the Argon gas module, into the models
Excell NHP-400/DA and Excell NHP-250/DA, the two outputs
can also be activated as follows:
• Both of them by the double pedal foot-switch, or both of them
by the hand-switches placed on the electrodes holder
handles: one is for electro-surgery, and the other one for
electro-surgery with Argon gas.
