Maintenance Manual

General description

The ESG-100 electrosurgical unit enables the user to perform common monopolar

and bipolar applications. Both can be operated in cutting and coagulation modes. The

electrosurgical unit is equipped with a user friendly display that allows the user to

select from a list of optimized modes. All settings are saved automatically and are at

the user’s disposition when switching on the electrosurgical unit the next time or when

the user changes the modes during a procedure.

The electrosurgical unit is equipped with a high voltage power supply which allows fast

control of the output resulting in safely controlled tissue effects and protection against

over- and under-dosage. In addition, the integrated high power cut support (HPCS) is

a precondition for optimized cutting procedures without initial delay.

Another feature of the electrosurgical unit is the fast spark monitor (FSM). This

technology measures the spark intensity in intervals of a few milliseconds when

cutting tissue. The fast spark monitor ensures the application of output powers that are

as low as possible and as much as necessary to achieve well defined tissue effects.

Moreover, the contact quality monitor (CQM) analyses continuously the contact

resistance of the neutral electrode, ensuring a safe application and minimizing the risk

of thermal injuries to the patient. The contact quality monitor status is continuously

displayed by visual indicators.

Finally, the leakage protection sensor (LPS) automatically monitors the high frequency

leakage current through the patient and produces a visual and acoustic signal if the

current is too high.

The footswitch middle pedal (34) may have three different functions:

1)

If the peristaltic pump unit is connected and switched on, the footswitch middle

pedal (34) activates the pump flow.

2)

If there is no communication of the electrosurgical unit with the pump, the user

has the possibility to choose between two functionalities:

2a) The user toggles between the modes as it is done by the toggle button (7) at the

front panel (see fig. 4.1). The change will be indicated by a beep tone. This is the

default setting.

Example: A bipolar coagulation mode is preset (e.g. SoftCoag). By pressing the

footswitch middle pedal (34) the user toggles between the bipolar modes (e.g.

RFCoag -> RFCoag + RCAP -> SoftCoag).

2b) The user changes either between monopolar cut and monopolar coagulation or

between bipolar cut and bipolar coagulation mode without using one of the select

buttons (1, 2, 3, 4) at the front panel (see fig. 4.2). The change will be indicated

by a beep tone.

Example: A monopolar cut mode is preset (e.g. Cut 1). By pressing the footswitch

middle pedal (34) the user changes to a monopolar coagulation mode (e.g.

ForcedCoag 1). The last used coagulation mode will be called.

To use the function 2b), change the footswitch function in the service menu as

described in chapter 12 (Service operation mode).

DANGER

Connect the power plug of the power cord directly to a grounded wall

outlet or to a multiple power socket outlet equiped with an insulating

transformer of protection class I, conforming to IEC 60601-1. The

multiple power socket outlet shall conform with the requirements of the

IEC 60601-1-1 standard. In this case, observe the maximum permitted

current or power loading of the multiple power socket outlet and the

insulating transformer.

WARNING

Firmly plug in the power cord so it will not accidentally be dislodged

during the operation.

CAUTION

Always use the power cord provided with the electrosurgical unit or a

cable of similar quality (see chapter 14.4, Technical data). Never

attempt to modify the power cord.

If the same circuit breaker is used to supply power to other electrical

equipment, carefully consider the power requirements of the additional

equipment and use circuit breakers that have ample capacity.

Otherwise, the electrosurgical unit does not work correctly.

Portable multiple power socket outlets must not be placed on the floor.

Do not use an additional extension cable or other multiple power

socket outlets that are not expressly approved by the manufacturer for

joint use.

NOTE

Before connecting to the power supply, check that the supply voltage

agrees with the electrical data on the type plate of the electrosurgical

unit.

If the voltage of the facility is different from the voltage indicated on the

type plate of the electrosurgical unit, contact Olympus.
