PREPARATION FOR USE

5.0.1

On the Generator check to make sure that the power switch is in the OFF position.

5.0.2

Connect the power cord to a 3-wire ground AC power receptacle.

5.0.3

Insert the Neutral Pad plug into the receptacle on the front panel marked "Neutral".

5.0.4

The Neutral Pad should be reliably attached as per Section 2.1.2.

5.0.5

Plug the handpiece into the appropriate receptacle on front panel.

5.0.6

Make sure that the electrode is seated fully so that no conductive shaft is exposed.

WAVEFORM SELECTION

Reference Section 7 – Power output characteristics for more details about waveforms.

5.1.1

CUT - For micro-smooth cutting

5.1.2

CUT/COAG - For cutting with coagulation

5.1.3

HEMO - For pure Hemostasis-Coagulation to control most forms of bleeding.

5.2

SMOKE HAZARD

By-products of high frequency surgical procedures are an occupational exposure hazard.

Standards based policies and procedures must be developed in all practice settings to protect

personnel.

VI. SURGICAL DESCRIPTION AND USE

6.0

LEARNING TO USE RADIOSURGERY

Before making contact with the tissue, the power intensity must be selected and the foot pedal or

fingerswitch must be activated. During the actual cutting, it is important to use a smooth uninterrupted

motion with light, even pressure. The movement should not be too slow. If it is, the build-up of lateral

heat in the tissue may cause charring, followed by necrosis and sloughing (see Preoperative Cutting

Practice Section 6.1). When performing a second or third cut in the same surgical site, allow

approximately ten seconds for the tissue to cool between applications of the electrode to the site.

Unlike a steel scalpel or standard electrosurgery, Radiosurgery

pressure to cut. Therefore, a light, smooth, continuous, and brush-like stroke should be developed.

Tissue damage will occur if heat is allowed to accumulate to the point where excessive

dehydration occurs. The spread of lateral heat in tissue depends upon various factors as indicated

in the following formula:

Lateral Heat+

Additionally the electrode type and selected waveform impact the thermal build up.

A. Time of Electrode Contact

B. Power Level

C. Frequency – Tissue provides lower resistance to higher frequencies, reducing thermal build up.

D. Electrode Type – A broader electrode tip requires more power and creates greater thermal spread.
