These units are intended to be used for
GYNAECOLOGY, ORTHOPAEDICS, ORL, UROLOGY, MAXILLOFACIAL SURGERY, DERMATOLOGY,
PLASTIC SURGERY, VASCULAR SURGERY, GENERAL OR THORACIC SURGERY, PAEDIATRIC
SURGERY, EMERGENCY SURGERY, GASTROENTEROLOGY, VETERINARY AND OTHER.
BASIC WARNINGS
The HF electrosurgical units are basic to solve many surgical needs, but the use of the HF currents also causes
specific risks and undesired side effects. Since the behavior of users is basic to reduce many risks, the
International IEC Standards for the safety of these devices establish:
All the hardware and software countermeasures needed to reduce risks.
All the warnings to detail in the use manual in order to inform operators about the safest way to use
them.
Because of previous reasons it is very important the following
That the device is used, only for the purposes listed in this manual, by qualified operators who are
experienced in electro
‐
surgery and all the related problems, risks and undesired side effects.
That users, before using the device, read this manual very carefully.
That operators use this device when applying all the warnings detailed in this manual.
GENERAL INFORMATION
Never use the unit if the electrical plant and the installations of the operating theatre do not comply with
the current safety standards. Never use extensions for the mains cord and, if many devices are
connected at the same time, ask the Technical Service about their compatibility.
Try to follow the suggested working times.
The smoke produced during the use of all HF units is biologically noxious. In USA, ENGLAND and so on
the Governmental and Technical Bodies recommend the use of Smoke evacuators to reduce this risk.
Always place the patient properly for the operation, especially in case of a long operation. The risk of
both burns and decubitus lesion rises in this case.
When using an HF unit for endoscopic procedures under liquid, it is advisable the monitoring of the
quantity of irrigation fluids in the patients (input and output volumes), mainly if they have a poor renal
function or cardiovascular insufficiency.
The unit is provided with self
‐
check systems which detect all faults, the mistakes of use, the absence or the
decrease of the power, the delivery of a power higher than that expected. The systems perform an auto
‐
check at
the switching on and they check the functioning during use. If the systems detect problems during the auto
‐
check,
they block the usability of the unit. If the systems detect problems during use, they stop the functioning. In all
cases, the systems inform the users by acoustic or visual signals and codes.
Because of this reason:
If, during use, the device doesn’t deliver the power (The normal powers appear less efficacious), but it has
properly passed the auto
‐
check at the switching on and the systems do not signal problems, users must not both
increase too much the power and think that the problem depends on the unit.
Users must check:
The good contact between the neutral electrode and patient’s tissues while using monopolar currents. The
conditions of cables and connectors, by bending and pulling them (They mainly break close to the instrument).
The assembly and the internal connections of all instruments, mainly if for endoscopy or laparoscopy. The
insulation of the blades of all bipolar scissors. (The continuous sliding damages it and causes a short circuit which
does not allow the current to reach tissues).
Users must clean:
The tips
of all electrodes and instruments (If dirty, the current doesn’t reach tissues). The joints of the bipolar
instruments for laparoscopy (If dirty the current doesn’t reach tissues).
USE OF FLAMMABLE SUBSTANCES OR EXPLOSIVE GASES
Never use flammable substances (cleaning substances, disinfectants and so on) or explosive anesthetic
gases (i.e. oxygen, nitrogen protoxide) when using a HF device ! It is very dangerous since the spark
normally generated, during use, by the HF currents may cause the explosion of gases or the fire of
flammable materials and materials (cotton, gauze, sheets) which are oxygen saturated or soaked with
flammable substances.
Remember that, during use, a spark may cause the explosion of endogenous gases (I.E. Inside the
intestine).
