FUNCTIONAL DESCRIPTION
The Bovie® Specialist | PRO is a multipurpose electrosurgical generator for use in physician’s offices and surgi-centers.
It provides unsurpassed performance, ®flexibility, reliability, and user convenience in one compact package.
The Bovie® Specialist | PRO Electrosurgical Generator includes digital technology. This new technology is evident in
the self-checking circuitry and error code readouts. The unit offers monopolar and bipolar electrosurgical operations.
The following are Bovie® Specialist | PRO key advantages and benefits.
Power Capabilities
Up to 120 watts of Pure Cut @ 500 Ω.
Up to 90 watts of Blend @ 800 Ω.
Up to 80 watts of Coagulation @ 1000 Ω.
Up to 40 watts of Fulguration @ 1000 Ω.
Up to 30 watts of Bipolar @ 200 Ω.
Two Levels of Coagulation:
Pinpoint Coagulation and Fulguration
Pinpoint coagulation provides precise control of bleeding
in localized areas.
Fulguration provides greater control of bleeding in highly
vascular tissue over broader tissue surface areas.
Return Electrode Monitoring System
The unit incorporates a return electrode contact quality
monitoring system (RECQMS). This system determines
the type of patient return electrode attached (single plate
or split plate).
It also continuously monitors the contact impedance
between the patient and the split plate patient return
electrode.
Contact impedance is only monitored when approved split
plate patient return electrodes are used.
Memory
The unit automatically powers up to the Cut and Coag
modes and their last selected power settings. If the Blend,
Fulguration or Bipolar mode is selected, the unit will
default to that modes’ last set power setting.
Floating RF Output
This minimizes the potential of alternate site burns.
Standard Front Panel Connectors
These connectors accept the latest monopolar and bipolar
instruments.
Self-Diagnostics
These diagnostics continually monitor the unit to ensure
proper performance.
Whenever they detect a problem, medical personnel
receive audible and visual alarm responses, and the output
is suspended until the alarm condition is cleared.

with an equipotential cable.
Connect the power cord to a wall receptacle having the correct voltage. Otherwise, product damage
may result.
CAUTIONS:
Do not stack equipment on top of the generator or place the generator on top of electrical
equipment. These configurations are unstable and / or do not allow adequate cooling.
Provide as much distance as possible between the electrosurgical generator and other electronic
equipment (such as monitors). An activated electrosurgical generator may cause electrical
interference with them.
Do not turn the activation tone down to an inaudible level. The activation tone alerts the surgical
team when an accessory is active.

Active Accessories
WARNINGS:
Shock Hazard –Do not connect wet accessories to the generator.
Shock Hazard –Ensure that all accessories and adapters are correctly connected and that no
metal is exposed.
Fire / Explosion Hazards
WARNINGS:
Danger: Fire / Explosion Hazard - Do not use the Bovie® Specialist | PRO electrosurgical generator
in the presence of flammable anaesthetics.
Fire / Explosion Hazard - The following substances will contribute to increased fire and
explosion hazards in the operating room:
•Flammable substances (such as alcohol based skin prepping agents and tinctures)
•Naturally occurring flammable gases which may accumulate in body cavities such as
the bowel
•Oxygen enriched atmospheres
•Oxidizing agents (such as nitrous oxide [N20] atmospheres).
The sparking and heating associated with electrosurgery can provide an ignition source.
Observe fire precautions at all times. When using electrosurgery in the same room with any
of these substances or gases, prevent their accumulation or pooling under surgical drapes,
or within the area where electrosurgery is performed.
The use of flammable anaesthetics or oxidizing gases such as nitrous oxide (N2O) and oxygen 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.
Non-flammable agents should be used for cleaning and disinfection wherever possible.
Flammable agents used for cleaning or disinfecting, or as solvents of adhesives, should be
allowed to evaporate before the application if HF surgery. There is a risk of pooling flammable
solutions under the patient or in body depressions such as the umbilicus, and in body cavities
such as the vagina. Any fluids pooled in these areas should be mopped up before H.F. surgical
equipment is used. Attention should be called to the danger of ignition of endogenous gases.
Some materials, for example cotton, wool and gauze, when saturated with oxygen may be ignited
by sparks produced in Normal Use of the HF surgical equipment.
No modification of this equipment is allowed.
Electric Shock Hazard - Connect the power cord to a properly polarized and grounded power
source with the frequency and voltage characteristics that match those listed on the back of the
unit. Do not use power plug adapters.
To avoid risk of electric shock, this equipment must only be connected to a supply mains with
protective earth.
Electric Shock Hazard - Always turn off and unplug the generator before cleaning.
Fire Hazard - Do not use extension cords.
CAUTIONS:
Accessories must be connected to the proper receptacle type. In particular, bipolar accessories
must be connected to the Bipolar Instrument receptacle only. Improper connection may result in
inadvertent generator activation or a Contact Quality Monitor alarm.
Set power levels to the lowest setting before testing an accessory.
