Power Adjustment; Sparking In Non-Insulated Haemostatic Forceps To Produce Coagulation; Caution With Accessories - WEM SS-200E Manual De Utilización

4.6.3 – Power adjustments
The table below shows typical power setting for each type of surgery. It is advisable to start the surgery at
the minimum settings and increase progressively the power value until the desired effect is obtained.
Each case should be evaluated by the physician in charge. Power adjustment may vary according to each
patient and the surgeon's experience.
Values below derive from experimental data obtained from previous surgical procedures.
Power
Low power
<30 watts
Medium power
Cut: 30 – 100 watts
Coag: 30 – 60 watts
4.7 – Sparking in non-insulated haemostatic forceps to produce coagulation
For vessel haemostasis in a monopolar surgery, the use of insulated monopolar forceps is recommended.
However, since it is required to be made without an insulated accessory, some recommendations should
be followed to reduce the risks of burns in the surgeon's hand.
1. Do not place it on the patient or the bed during the sparking process.
2. Use the cut function instead of coagulation function. Cut function has voltage levels lower than
coagulation function, what reduces the current quantity.
3. Use the lowest power possible.
4. Hold strongly the forceps by the largest contact area possible. This procedure helps to disperse the
current and reduce the current concentration in the surgeon's hands.
5. Activate the electrosurgical unit only after the pencil tip has made contact with forceps.
6. Contact between pencil tip and forceps should be made below the surgeon's hand level and as close
to the patient as possible to reduce the current deviation by the surgeon's hand.
4.8 – Caution with accessories

Before each use, check the conditions of preservation of electrode cables (pencil, forceps, etc...) and
insulation (dryness, splitting, and faults), broken cables, broken connector, and replace them to prevent
safety risk to the patient and operators.
 Adhesive patient plates should be discarded after each use.
 Do not wind patient plate or accessory cables on metallic objects. This procedure may induce potentially
dangerous currents in such objects that can cause shocks and burns to the patient and surgery team.
 Do not connect wet or internally humid accessories to the electrosurgical unit. There could be risk of
electric shock.
 When more than one accessory is connected to the electrosurgical unit, for example, a handswitch
pencil and two footswitch- pencils, care should be taken to maintain the accessories that are not being
used in a safe place, for example, a plastic or fabric bag that can be attached to the surgical area, thus
avoiding undesirable burns.
 An apparently low power or a failure in correct operation of equipment under normal operation may
indicate a defective application of a neutral electrode or a poor contact in its connections (see Important
Recommendations for Patient Plate Application – item 4.4).
 The user must ensure that accessories connected to equipment will support at least the maximum peak
output power in the operation and power adjustment mode used (see graphs in item 1.7).
