The Power Setting - Cooper Surgical LEEP PRECISION LP-20-120 Manual De Funcionamiento

14 . CABLE PLACEMENT: High frequency cables should be routed clear of other instruments and arranged for
minimum length . Cables to surgical electrodes should be positioned to prevent contact with the patient or
other leads . Temporarily unused active electrodes should be stored in a location isolated from the patient .
15 . R/F LEAKAGE: The LEEP PRECISION Generator has a sensitive error detection mode that disables the
output and indicates that an error condition exists by illuminating the front panel R/F LEAKAGE ERROR LED
(red) . This LED will indicate that an undesirable path exists from the Patient Return Electrode or Active
Electrode to ground . In this context ground means any undesirable path or place . If such a path exists, the
patient should be inspected for any contact with metallic paths to tables, chairs, or other non-isolated objects .
The purpose of this feature is to prevent R/F current from flowing in undesirable places where it could either
cause burns or damage to ancillary equipment .
16 . PATIENT CONTACT: Direct operator-to-patient skin-to-skin contact could create an undesired leakage path .
Avoid skin-to-skin contact by padding with dry gauze as necessary . The operator should wear electrically
insulating gloves . Unless absolutely necessary, the patient should not be touched when R/F power is
activated . Patient should not come into contact with grounded metal parts or parts with a higher capacitance
to ground (i .e ., operating table supports) . Use of anti-static sheeting is recommended for this purpose .

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:
WAIT = Red
BLEND = Yellow
CUT = Yellow
COAG = Blue
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 on
pages 16 and 17 . If the power is too high, the tissue will be discolored and there will be considerable sparking
when the electrode contacts 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 .
