UNIT OPERATION
The McKesson Argent High Frequency Electrosurgical Desiccator produces radio frequency current which is
useful for the removal and destruction of superficial cutaneous and mucosal lesions. This is done by performing
desiccation and fulguration procedures. Electrosurgical desiccation occurs when the electrode is placed directly
onto the surface of the lesion. Fulguration occurs when the electrode is held slightly above the lesion and an
arc is delivered to the lesion. The unit also provides fast and efficient bleeding control by coagulation of
capillaries and small blood vessels.
For the majority of desiccation, fulguration, and coagulation procedures utilizing the standard handpiece in the
monopolar output, the patient plate is optional. When used, the patient plate will intensify the coagulation
properties of the unit and also lessen the opportunity for an electrosurgical burn. The optional footswitch adds
versatility when using the standard handpiece in the monopolar output, as the footswitch allows you to
activate the unit by either the handpiece or the footswitch. Bipolar outputs are available for those physicians
who prefer to utilize bipolar forceps to perform coagulation procedures. A footswitch is required when using
the bipolar output and the patient plate is not used. Procedures that are performed in sensitive areas may
require an anesthetic. Flammable anesthetics should not be used.
If you are unfamiliar with the operation of a low powered electrosurgery unit, it is advisable to practice on
chicken or lean flank steak to visualize the effects at various output and power levels.
INSPECTING THE DESICCATOR AND ACCESSORIES
Before each use of the desiccator, verify that the unit and all accessories are in good working order:
• Inspect for damage to the desiccator and all its connections.
• Verify that the appropriate accessories and adapters are present.
• Inspect all cords and connectors for signs of wear, damage, and abrasion
(e.g. under magnification)
• Verify that no errors occur when you turn on the unit.
