1. Purpose of the ES120 system
The electrosurgic l system ES120 is ll-purpose di thermy b sed on high-frequency current
flow. ES120 is designed for use in electrosurgic l tre tment:
• pure cutting ,
• blend cutting with hemost sis ,
• soft co gul tion,
• forced co gul tion,
• bipol r co gul tion.
2. Electrosurgery basics
Currently electrosurgery is used in ll kinds of surgic l procedures. In order to use
electrosurgery effectively, it is necess ry to le rn, underst nd nd pply s fety rules designed
to protect both the surgeon nd the p tient.
Surgic l di thermy unit uses electricity to gener te high - frequency (HF) ltern ting current.
The therm l effect c used by the HF current flowing through the tissue is used for tissue
cutting or co gul tion. Surgic l di thermy unit gener tes ltern ting current of frequency
higher th n 300 kHz. Due to th t there is no risk of unintended electrolysis effect or muscle
nd nerve stimul tion.
When working with a surgical diathermy unit always remember the
two fundamental rules:
•Current flows along all the available paths.
•HF leakage current flows between two adjacent conductors
even if they are separated from each other.

ES120 OPERATION MANUAL IU ES120 2009-03-01 ENG.3.0
2.1. Monopolar operation
In the monopol r mode the HF current is delivered to the
tissue by the ctive electrode. The cutting or co gul tion
effect results from the concentr tion of the high density
HF current on the sm ll surf ce of the ctive electrode.
This c uses the incre se of temper ture nd ev por tion
of w ter from the tissue in the direct vicinity of the ctive
electrode nd eventu lly results in hemost sis nd rrest
of bleeding, or cutting of tissue.
Subsequently the HF current flows to the surf ce of the neutr l electrode where it is dispersed.
The density of the HF current decre ses nd no unintended therm l effect occurs t the spot
of the neutr l electrode pplic tion. From the neutr l electrode the HF current returns to the
di thermy unit.
2.2. Bipolar operation
When the device oper tes in the bipol r mode HF current
flows between two j ws of bipol r instrument nd
concentr tes exclusively on the sm ll re loc ted between
them.
In the bipol r mode the d ngerous flow of current through
the p tient's body does not occur. The risk of burns
occurring outside the immedi te surgic l re is minimized.
Thus the bipol r co gul tion mode is s fer th n the monopol r mode nd is p rticul rly
recommended for procedures involving p tients with c rdi c p cem kers or for procedures
performed on org ns of sm ll cross-section. In the bipol r mode, the neutr l electrode is not
required.

7. Preparation of the system for work
The system is prep red for work by connecting the power le d nd ccessories.
The supply cable c n only be plugged or unplugged when the gener tor is off. The gener tor
is m de in ccord nce with the 1st cl ss of fire-h z rd protection, nd so it requires
grounding pin in the power supply socket. The power supply socket is loc ted on the b ckside
of the c sing (Fig. 4, pos. 8).
The gener tor does not require ny ddition l grounding pins (Fig. 4, pos. 6). It is used for
grounding if socket without grounding is used or in pl ces where the fire protection system
requires it.
The foot switch is connected to socked 5 in the b ck side of the enc sing (Fig.4).
The connection mode of the ccessories is expl in in Fig. 5.
The neutr l electrode is not needed for performing bipol r procedures. More inform tion
bout the neutr l electrode c n be found in Section: “8.2. Neutr l electrode control ”

use equipment with visible defects nd d m ged insul tion.
•The neutr l electrode should be pplied to dhere to the p tient’s body with its entire
surf ce.
•The reus ble silicone electrode should be tt ched with speci l t pe for neutr l
electrode fixing to prevent it from moving
•The electrode should be pl ced in the vicinity of the oper tive field but no closer th n
20 cm from it.
•When pplying the neutr l electrode m ke sure th t it f ces the oper tive field with its
longer side. This requirement does not pply to the dispos ble TwinS fe electrodes
which c n be pplied in ny position.
•The electrode should not get wet or be wr pped in nything .
•Do not spre d conductive gels on the surf ce of the neutr l electrode.
•No fluids should enter between the body nd the electrode.
•When performing procedures on sm ll children electrodes of ppropri te size should
be used: newborn or b by.
•When disconnecting the neutr l electrode, never do it by pulling the c ble.
• Under no circumst nces try to rep ir the neutr l electrode by yourself.
Remember that a rubber electrode loses its conductive properties as active substances are
rinsed out from the rubber. Such an electrode increases the risk of burns. Therefore not only
the devices but also the reusable electrodes should be subject to regular inspections.
Before attaching the neutral electrode read the instructions supplied by the manufacturer.
ALWAYS follow the manufacturer’s directions printed on the packaging of
the neutral electrode. Reusable passive electrodes should be disinfected
before use (see chapter 11 "Generator and accessories maintenance”).
