The Power Setting; Cutting Techniques - Cooper Surgical LEEP PRECISION LP-10-120 Bedienungsanleitung

8.2 The Power Setting

Select the operating mode (CUT, BLEND, COAG, or WAIT) by using the mode selector buttons . When a mode
is selected, the intensity should be set by depressing the POWER RAISE (
controls the digital display . When a mode is selected, the corresponding LED illuminates in the corner of each
button to verify which mode is engaged .
To ensure correct operation of the instrument, the colors are correlated to international standards:
When the Foot Switch is depressed, or the Hand Switch Buttons are pressed, the R/F ON
illuminate . If either the CUT (
depressed, the output will be active . In the WAIT (
Annunciator will indicate with an intermittent tone when the R/F Power is present at the output . Once contact
is made with the electrode to the tissue and a small current is flowing, the tone will become steady.
The ideal power setting is the minimum setting at which cutting and coagulating meet the criteria described in
Sections 8 .4 – 8 .6 . If the power is too high the tissue will be discolored and there will be considerable sparking
when the electrode makes contact with the surface . If the power is too low the electrode will drag through the
tissue, tearing and burning instead of cutting cleanly, and will pick up shredded and torn tissue .
Power requirements will vary with the type and size of the electrode, the area of electrode surface in contact
with the tissue, the nature of the tissue, whether cutting or coagulating, and the depth of the incision desired .
Larger electrodes, deeper incisions, and tough fibrotic tissue are some indications for higher power settings.
Do not use fine Needle Electrodes at high settings as they may be severely damaged by such
use . When practicing with these electrodes, work up gradually from a low setting . Generally,
you should not exceed a setting of 40 with fine Needle Electrodes.
Do not use monitoring Needle Electrodes during electrosurgery . If monitoring electrode cables
are used, they should be placed as far away from electrosurgical cables AS POSSIBLE . If it is
absolutely necessary to cross over any monitoring cable or patient-connected tubes, such as
IV lines, the crossing should be at right angles . Use of monitoring systems incorporating high
frequency current limiting devices is recommended .

8.3 Cutting Techniques

When cutting, ALWAYS activate the electrode by stepping on the Foot Switch or pressing the yellow button on
the Active Electrode (Pencil) BEFORE making contact with the tissue .
Plan the stroke . Before activating the electrode, take one or two practice strokes to be sure you can
complete the planned stroke comfortably and correctly . At this time you can evaluate the size and shape
of the electrode and the speed and depth of the stroke .
When the practice stroke is comfortable, step on the Foot Switch or press the yellow button on the Active
Electrode (Pencil) and make the planned cut .
Use a smooth brushing motion without pressure . The electrode should pass through the tissue, WITHOUT
DRAGGING, at a deliberate but not slow speed .
Keep the electrode moving . Prolonged contact with any one part of the tissue can create excessive
coagulation .
