ConMed hyfrecator 2000 Operator's Manual page 9

Failure of the unit could result in an unintended increase of output power.
When used, the neutral electrode (patient plate) should be reliably attached with the entire surface
area in contact with the patient's body and as close to the operating field as possible. When not in
use, the neutral electrode should be disconnected from the Hyfrecator® 2000 to avoid accidental burns.
Apparent low output or failure of the Hyfrecator® 2000 to function correctly at normal operating
settings may indicate a faulty green wire ground connection. This could be due to a faulty power
cord, loose connections inside the unit, the use of a two wire extension cord, or the use of a three-to-
two prong adapter. These faults can result in a burn if the patient plate is used and is not in good
contact with the patient. If the neutral electrode (patient plate) is being used, the low power may be
due to faulty application or poor contact in its connections. In this case, the application of the
neutral electrode and it's connections should be checked before selecting a higher power.
Skin to skin contact (for example, between the arms and body of the patient) should be avoided by
the insertion of dry gauze or other suitable means.
When the Hyfrecator® 2000 and physiological monitoring equipment is used simultaneously on the
same patient, any monitoring electrodes should be placed as far as possible from the surgical
electrodes. Needle monitoring electrodes are not recommended. In any case, monitoring systems
incorporating high frequency current limiting devices are recommended.
The use of flammable anesthetics or oxidizing gases such as nitrous oxide (N
should be avoided if a surgical procedure is carried out in the region of the thorax or the head, unless
these agents are sucked away or flammable anaesthetic-proof equipment is used. The Hyfrecator®
2000 is not flammable anaesthetic-proof equipment.
Do not use the Handswitched Pencil with a footswitch. The unconnected switch connector can arc to
nearby objects or personnel and cause a burn.
Connect the generator electrical cord to a properly grounded receptacle. Do not use extension cords
or two wire adapters.
Do not connect wet accessories to the generator.
The Hyfrecator® 2000 must be mounted vertically to reduce the possibility of spilled liquids entering
the chassis and adversely affecting the safety of the unit.
Anesthesia
As in other types of surgery, the amount and type of anesthetic required for procedures depends upon the
site of the operation and the tolerance of the patient. Small lesions can sometimes be removed without
anesthetics when they are not in sensitive areas. Do not use explosive or flammable anesthetics due to the
presence of the spark created by the HYFRECATOR® 2000. Similarly, when the site is cleaned with alcohol
or other flammable cleansing agents, dry the surface thoroughly before proceeding.
Monoterminal Shock
In all electrical devices where a current is emitted from the instrument, the current must have a return path.
The return path for monoterminal applications is through the patient's body, to the ground and back to the
instrument. In this mode, if any portion of the patient's body comes in contact with a grounded metal
object, such as a chair or metal rail, the current will take the path of least resistance and a slight shock may
be felt. To minimize the possibility of shocking during monoterminal applications:
• Do not let your patient come in contact with any grounded metal objects.
• Position the electrode on or close to the patient before activating the output.
• For procedures using the dispersive plate, do not allow the patient to break contact with the dispersive
plate when the unit is activated.
• If the physician or nurse must touch the patient, place hand on the patient before activating the
HYFRECATOR® 2000. Do not break contact during activation. To lessen the possibility of a shock,
wear gloves at all times and continue to avoid contact with grounded metal objects.
