ELECTROSURGICAL UNIT

Using Two Electrosurgical Units

4.54 This electrosurgical unit has dual monopolar outputs
(first come first served) and simultaneous bipolar output.
It is therefore very unlikely that another electrosurgical unit
would need to be used on the same patient at the same
time, however if it is necessary follow the guidelines
detailed in section 4.55.

4.55 In certain procedures it is convenient or even
essential that two electrosurgical units are used on the
patient at the same time.  There is no reason why such
operations should not be safely carried out if the following
points are observed:

  ♦

Do not use a fully floating output unit with an earth
referenced unit or even a partially floating unit, for
example:

  ♦

Eschmann TD411 or DS402 and a Valleylab
Force 4

  ♦

Eschmann TD411 or DS402 and a GU Solstar
or any older GU unit.
Note:   All Eschmann units have fully floating
outputs and any two may be used in
combination.

  ♦

Always use two plate electrodes, one for each unit.
Never join plate cables or overlap plate electrodes.

  ♦

Position each plate electrode as close as possible to
the respective operation site.  Do not allow
electrosurgical current paths to intersect, e.g. if the
main procedure is in the thoracic region, the plate
electrode for this unit should be placed on the patient’s
back, buttocks, or upper thigh.  If the secondary
procedure is vein removal from the leg, the second
plate electrode should be placed on the thigh or calf
of this leg.

  ♦

For maximum safety use fingerswitches wherever
possible.  This reduces the possibility of inadvertent
activation of either unit’s output.  Always use two
quivers, one for each active handle or fingerswitch.

Using a flexible endoscope

4.56 To ensure that the endoscope connection socket is
not used without a documented procedure in place, the S-
Lead socket (29, Fig.11) is blanked of with a plug to avoid
inadvertent use. Before removing this plug the following
notes should be considered when writing a procedure for
the use of this electrosurgical unit with an endoscope.

  a.

To avoid the risk of potential burns caused by h.f.
voltages on the body of the flexible endoscope some
users may prefer to connect the endoscope to the
TD830 Electrosurgical unit. This is accomplished

using an S-Lead [REF 83-139-41 (Olympus 9mm),
or REF 83-139-49 (Pentax 8mm)] connected to the
S-Lead socket (29, Fig 12) of the TD830
Electrosurgical unit and the flexible endoscope.

  b.

When using a flexible endoscope low power settings
only should be used (e.g. maximums of 30% for cut,
50% for pinpoint coagulation). Also because of the
high voltage waveform of spray coagulation it should
only be used at very low power settings see 3 below.

  c.

It is important to ensure that the flexible endoscope
used is compatible with the voltages produced by
the TD830 Electrosurgical unit. The maximum
voltages produced by the TD830 Electrosurgical unit
for each mode and display setting are shown in the
graphs at the end of section 5. These should be
compared to the voltage rating of the flexible
endoscope. (Note: Flexible endoscopes complying
with IEC60601-2-18 should detail their voltage rating
in their accompanying documentation. If in doubt
consult the flexible endoscope manufacturer).

SERVICING

4.57 It is recommended  that electrosurgical safety
checks and routine servicing are carried out at regular
intervals (every six months) and only by Eschmann trained
personnel or Eschmann trained hospital engineers,
otherwise the warranty could be infringed.

4.58 Read the information given in this manual carefully
before using, cleaning, sterilizing, or servicing the
electrosurgical unit.
