ELECTROSURGICAL UNITS
FOR MAJOR SURGERY
EXCELL MCDS Series
|
|
EXCELL
with MCDS System is a new generation of electrosurgical units for high surgery, developed utilizing the most advanced
digital technology with double microprocessor to grant the highest possible level of performances and safety of
users and patients.
Suitable for every surgical monopolar and bipolar
application, the EXCELL MCDS line meets the
International Standards IEC 60601-2-2 for HF diathermy units, has EC approval 93/42 ECC and includes 4 different
models: EXCELL 400 MCDS, EXCELL 350 MCDS, EXCELL 250 MCDS and EXCELL 200 MCDS allowing the user to choose the most
suitable model for his specific need.
|
|
COMPLETE OVERALL PERFORMANCES
|
|
Thirteen different currents to meet every
need:
|
| |
|
| • |
four for monopolar cut
|
| • |
four for monopolar coagulation |
| • |
two for bipolar cut (only for models 400 MCDS and 250 MCDS) |
| • |
three for bipolar coagulation. |
| |
|
|
The monopolar and bipolar performances can be used independently and all units
can be used with argon coagulators.
|
|
Four currents all with sinusoidal wave form and electronically controlled starting impulse to grant the best performance
for every surgical procedure, under water too (TUR, TUVAP, and so on).
|
| |
|
| • |
PC - pure cut
|
| • |
BC I - blend cut with a minimum haemostatic
effect and modulated combination of cut and coagulation currents
|
| |
| • |
BC II - blend cut with a medium haemostatic
effect and modulated combination of cut and coagulation currents
|
| |
| • |
BC III - blend cut with a strong
haemostatic effect spray type and modulated combination of cut and coagulation
currents.
|
| |
| |
|
|
Four currents, all with automatic optimization system, ensure the best results for the coagulating action with
the lowest possible power in every surgical field, under water too.
The four currents are:
|
| |
|
| • |
PCS - Pin Point Contact, Soft: coagulation
extremely precise, with a minimum superficial effect and good deep action
|
| |
| • |
F - Fulguration: coagulation with
good superficial effect and deep action
|
| • |
SPR - Spray:
coagulation without
contact, with strong superficial effect and light deep action
|
| • |
A - Automatic: coagulation with pulsed
action to obtain the most delicate effect. This function is particularly suitable for laparoscopic
procedures,
reducing the undesired "smoking effect".
|
| |
| |
|
|
Two currents for the bipolar cut.
The two currents are:
|
| |
|
| • |
PC - pure cut with a minimum coagulating
effect
|
| • |
BC - blend cut with a strong coagulating
effect.
|
| |
|
|
Three currents for the bipolar coagulation to satisfy every specific need.
The three currents are:
|
| |
|
| • |
MP - Micro Precise: coagulation extremely
precise;
|
| • |
MPA - Micro Precise Automatic: coagulation
identical to the MP type but with an automatic Start/Stop system (impedance sensitive);
|
| |
| • |
SM - Standard Macro: coagulation
with a strong effect, for forceps with larger tips (the best for laparoscopy).
|
| |
| |
|
| All units can be used and operate independently as
follows:
|
| |
|
| EXCELL 400 MCDS and EXCELL 250 MCDS with:
|
| • |
Two double pedal switches for monopolar and bipolar
functions;
|
| • |
Two monopolar hand-switch handles or one with hand-switch and one with double
pedal-switch, all usable independently
by two surgeons
|
| |
| • |
bipolar electrode with double pedal-switch or with automatic Start/Stop system
(for coagulation only). |
| |
|
EXCELL 350 MCDS and 200 MCDS with:
|
| • |
a double pedal switch which can be used for the monopolar and bipolar functions; |
| • |
one hand-switch handle and one with double pedal-switch usable independently by two surgeons; |
| • |
bipolar electrode with pedal switch or with automatic Start/Stop system (for coagulation
only).
|
| |
| |
|
|
GENERAL CONTROL - MCDS System
|
|
All models are provided with a sophisticated and advanced control system by double
microprocessor including an autodiagnosis system both switching on the unit and during its working, that monitories
continuously all functioning parameters to grant the highest level of performances and
safety.
This system, in case of faults, stops automatically the working of the unit informing the users through specific
"error" codes on the display.
The system grants all the following performances:
|
|
Automatic adjustment of output powers with dynamic control and
stop in case of anomalies
ADC
System with OUTPUT ERROR CONTROL
|
|
All
output powers are controlled by two microprocessors which adjust and optimize them
automatically, carrying out
7000 tests every second and granting so, without intervention by the user, an efficacious and dynamic stabilization
of the output power in order to obtain the maximum efficiency with the lowest possible power in every surgical
field, independent of the patient tissues (impedances), the electrode used and its speed on the tissues.
This system
grants also the maximum safety because it is able to stop, in real time, the output power in case of internal
faults.
|
|
Functions setting |
|
The setting and
the adjustment of all the controls are on the front panel. This is organically
divided, completely smooth and it
is provided with a buttons-system with control display that allows a micro adjustment for the low powers (1 W at
a time for monopolar and 0.5 W at a time for bipolar performances).
|
|
Memorization |
|
The user can
personalize exactly specific performances memorizing 4 working programs which can be set by pushing a
button.
|
|
Neutral plate safety circuit - NPCC
System
|
|
This circuit allows to obtain very high level of safety controlling both the good connection and the quality of
the contact "neutral plate/tissues" (using specific disposable split
electrodes). It works as follows:
|
| |
|
| • |
When the contact is defective, it gives to the users a luminous signal reducing
at the same time the output power at 200 W safety level.
|
| |
| • |
It stops completely the output power, giving an acoustic and luminous signal
when the contact is insufficient, absent or the connection cable is broken or
disconnected.
|
| |
|
The efficiency of this circuit is tested both during the initial autodiagnosis
routine and during working with cyclical tests.
|
|
Leakage currents circuit control
|
|
The system checks the HF leakage currents and, if there are any load unmatching impedances
(patient), reduces automatically
the output RMS voltage to safety levels.
|
|
CONSTRUCTIONAL TECHNOLOGY
|
|
To guarantee the maximum reliability and solidity without any heating
problem,
the apparatus has been developed using the most modern technology for this kind of application and it is provided
of HF generator with mosfet power working according to the principle of free
oscillators.
To make easier the technical assistance, the unit is built with interchangeable boards and it is subjected to a
very severe testing procedures including also 100 hours of working at maximum power.
