3.0 SAFETY NOTES & ALARMS
Attention to the following points is necessary
in order to reduce the risk of accidental burns
during the use of this electrosurgical unit. Other
safety notes and warnings are also given within
the text of this manual and these should be
noted before using this electrosurgical unit.
DO:
♦
DO NOT:
Use only Eschmann accessories, in particular active ♦
and plate electrodes and cables which should ♦
preferably be no more than 3 metres in length. All
Eschmann accessories are rated above the
corresponding maximum peak output voltage of this
electrosurgical unit (see graphs in section 5). For
reference Eschmann accessories can be used safely
at the following h.f. peak voltages:
Bipolar active - 400 V peak
Monopolar active - 4000 V peak
Monopolar plate electrode - 2250 V peak
♦
♦
Use bipolar techniques in preference to monopolar, ♦
whenever possible. For surgical procedures on parts
of the body having a relatively small cross-sectional
area, the use of bipolar techniques may be desirable
♦
to avoid unwanted coagulation.
Seek approved qualified advice (e.g. cardiology
department) before using this electrosurgical unit on
patients with implanted pacemakers or other active
implants to avoid interference or damage to the implant.
♦
Monitor such patients carefully.
♦
Set power output controls to the minimum setting
before use and select the minimum power setting to
achieve the desired effect.
♦
Check all cables and accessories routinely before
use. In particular, electrode cables and endoscopically ♦
used accessories for possible damage to the insulation.
♦
Ensure the entire area of the plate electrode is reliably
attached to the patient’s body and as close to the ♦
operating field as possible.
♦
♦
Store temporarily unused active electrodes such that
they are isolated from the patient [e.g. use a quiver
♦
(REF 83-186-38) to hold active accessories when not

Do not use uninsulated forceps, monopolar or bipolar.
Do not place monitoring electrodes close to the
operating site. When high frequency surgical
equipment (i.e. electrosurgical equip-ment) and
physiological monitoring equip-ment are used
simultaneously on the same patient, any monitoring
electrodes should be placed as far as possible from
the surgical electrodes. Needle monitoring electrodes
are not recommended. In all cases, monitoring
systems incorporating high frequency current limiting
devices are recommended.
Do not allow active cables to drape across or contact
the patient's body or contact the cables or leads of
other equipment.
Do not use flammable anaesthetics, flammable
solvents or oxidizing gases such as nitrous oxide
(N2O) or oxygen if the surgical procedure is carried
out in the region of the thorax or head, unless these
agents are sucked away.
Do not allow the patient's body to touch conductive
objects. The patient should not come into contact with
metal parts which are earthed or which have an
appreciable capacitance to earth, e.g. operation table,
supports, etc. The use of antistatic sheeting is
recommended for this purpose.
Do not use hook type active cables (with or without
adapters designed for use with hook type cables) use
4 mm or 8 mm plug type active cables.
Do not reuse disposable plate electrodes.
Do not rely solely on surgical gloves to provide
insulation.
Do not allow ‘skin-to-skin’ contact (e.g. between the
arms and body of the patient), this can be avoided, for
example by the insertion of adequate dry gauze.

folds out at the end of this manual.
4.1 The TD830 electrosurgical unit provides two outputs
both for high power monopolar cut and coag (on a first
come first served basis), together with a separate output
for bipolar coag. Bipolar coag output is available
simultaneously with either monopolar output. The unit
incorporates touch button controls, seven segment LED
(light emitting diode) displays and LED visual indicators.
4.2 The digital displays can show two scale modes, one
shows the typical power available in watts the second
shows a numerical value up to 10 (the latter is only
displayed whilst digital display range selection toggle button
(35) is held pressed).
Monopolar standby mode
4.9 The unit can be switched into monopolar standby
mode, in which only bipolar power is available, using
monopolar standby selection button (32). This button is a
toggle switch, each press of the button will turn monopolar
mode ‘on’ (if ‘off’) or ‘off’ (if ‘on’). This button (32) can be
considered as an ‘on/off’ switch for monopolar, the
advantage being that if only bipolar outputs are required
and monopolar standby mode is selected, no plate
electrode needs to be connected to the unit. (If monopolar
standby mode is not selected for ‘bipolar use only’ and a
patient plate electrode is not connected to the unit the PAM
alarm or PCM alarm will activate). The unit is in monopolar
standby mode when only the digital display for bipolar can
be seen illuminated.
Note: The power delivered depends on the resistance
between the active electrode and the plate electrode (or
between the tips of bipolar forceps) at the time the power
is applied. This resistance can vary widely and many times Digital display options

ELECTROSURGICAL TECHNIQUES
General
4.14 When using electrosurgery, it must always be
remembered that its purpose is to cut, destroy or modify
tissue. This can occur at any point on the body where the
concentration of electrical current becomes sufficiently
high. Under fault, or misuse conditions, this current
concentration can occur on points on the body other than
the desired operation site and can cause burns.
4.15 To help reduce the possibility of such accidental
burns, the unit is fitted with a leakage limiting circuit in the
monopolar section. This circuit detects the conditions that
may lead to an increased possibility of accidental burns
from leakage and limits the leakage current accordingly.
The HF leakage limiter does not generate an alarm. In
addition, the following paragraphs give guidance for the
safe use of the electrosurgical unit.
4.16 With monopolar electrosurgery, the surgeon uses a
single point electrode to concentrate high frequency electric
current in the body tissues close to the electrode tip. If the
operating site is linked to the bulk of the body only by a
tissue path of small cross-sectional area, e.g. Fallopian
tube or penis, the surgical effect of the electrosurgery can
extend along it from the electrode with undesirable results.
♦
♦
♦
♦
♦
Do not apply the plate electrode adjacent to ECG
electrodes and cables, or to an area where fluids
could pool.
With babies and small children the plate electrode
should always be applied to the trunk section of the
body to give maximum contact with the skin. It is
unsatisfactory to attach the plate electrode to small
limbs where overlap of the plate electrode ends can
occur.
Subject to application instructions, the plate electrode
should be on a smooth, resilient, muscular site well
supplied with blood vessels and as close as possible
to the operating area. The site should be clean and
dry, and shaved of excessive hair. The plate electrode
should be securely attached with its whole area in
contact with the patient’s body.
Do not cut or modify the plate electrode in any way.
Do not reuse disposable adhesive plate electrodes,
as adhesive failure could occur.
4.21 Adhesive plate electrodes (REF 83-122-42 and 83122-46) with detachable cables, should only be used with
a connector cable (REF 83-122-93) that requires complete
insertion of the connector tab. This ensures that contact
between the tab and any conductive object cannot occur.
Footswitches
4.17 Normally the surgeon will have ensured that the
operating site is bounded by a bulk of tissue into which the
current can disperse, so that the cut or coagulating effect
is limited to the tissues close to the electrode. The current
then disperses into the body and leaves it by way of the
relatively large plate electrode, having passed harmlessly
through any intervening tissue and organs.
4.22 Footswitches (REF 83-581-09 and 83-581-13 for
yellow, or REF 83-581-17 and 83-581-25 for blue, or twin
footswitches REF 83-109-39 and 83-109-47) must always

cables fitted with ‘hook’ type connectors (those detailed
above are suitable for use with this unit). The absence of
exposed metal parts on pin or jack plug designs reduces
the risk of operator burns compared to cables with the
‘hook’ type design.
Power Control
4.33 Use only the minimum power control setting
necessary to produce the desired electrosurgical effect.

Active Cables
Current Paths
4.27 Active cables of the ‘hook’ type have been replaced
by pin or jack plug designs (REF 83-135-12, 83-137-17,
83-138-06 and 83-138-22) any of these are suitable for
use with this unit. Old style cables with ‘hook’ type
connectors should not be used. The absence of exposed
metal parts on pin or jack plug designs reduces the risk of
operator burns compared to cables with the ‘hook’ type
design.
4.36 The path of an electrosurgical current through a
patient's body should, whenever possible, be the
shortest path. If it is suspected that this path could be
bypassed, for example between limbs, an insulating
medium should be used.
4.37 It is advisable that skin to skin contact between
parts of the patient's body, for example between the

Active Electrodes

should always be used. Electrodes should be kept clean
during use either by wiping with a solvent on a sterile swab General
or by using a sterile abrasive pad.

4.30 Ball type coag electrodes should be discarded if the
surface becomes pitted. Do not sterilize electrodes which
are designed as ‘single use disposable’ (also see the leaflet
detailed in section 1, supplied with all accessories ).
Fingerswitches
4.31 For many procedures, ‘on/off’ control of cut and coag
outputs by means of buttons on a fingerswitch offers the
surgeon more precise control. Reusable fingerswitches
have only a limited number of re-sterilization cycles.
Regular testing and inspection is therefore essential. Do
not sterilize and reuse ‘single use’ types.
4.32 Do not connect footswitches to the USER 1 output
of the electrosurgical unit when a fingerswitch is being used
to control the USER 1 output.

4.40 With bipolar techniques, the electrosurgical
current flows mainly between the tips of the bipolar
forceps or between the contact points of a special
purpose electrode and therefore does not require a
plate electrode. Bipolar electrosurgery is safer than
monopolar, the main safety requirements are:
♦ Always use Eschmann bipolar accessories.
♦ After sterilization, always ensure that the
accessories and cable connector are completely
dry.
♦ Always ensure that accessories are sterilized by
a process compatible with the accessory, consult
the accessory leaflet provided with all Eschmann
accessories (publication number E-IM50 part
number 604802).

are kept a few inches away from the pacemaker pulse

4.44 If in monopolar electrosurgery the intervening tissue
and organs contain an implanted pacemaker and its leads,
it is possible under certain conditions that the
electrosurgical current will have undesirable effects. The
following notes offer guidance on the risks and on possible
precautions.
WARNING
For patients with cardiac pacemakers or other
active implants, a possible hazard exists
because interference with the action of the
pacemaker may occur or the pacemaker may
be damaged. In case of doubt, approved
qualified advice should be obtained.
Risks
4.45 Operating with electrosurgical equipment on patients
who have an implanted pacemaker incurs the risks of
affecting the pacemaker's operation, either by direct contact
or by radiated interference, and of inducing burns at the
pacemaker electrode implantation site. Clearly the risks
are very much lower with bipolar than with monopolar
electrosurgery, because of the highly localised current path.
Precautions
WARNING
More severe consequences, local heating and
destruction of the pacemaker circuit
(Reference ¹), would result if an electro-surgical
electrode touched the pacemaker.
Electrosurgical Interference
4.50 Electrosurgical equipment can produce interference
with other electromedical apparatus used in the operating
theatre. Particular attention should be given to the selection
of ECG monitors with good interference rejection if it is
desired to monitor the patient when the electrosurgical
equipment is active.
4.51 In certain conditions a reduction in ECG interference
can be obtained by placing the ECG electrodes closer
together than normal. Modern monitors with high input
isolation allow electrode placement close to the
electrosurgical plate electrode, if required.
4.52 It is inadvisable to use mobile telephones or ‘walkietalkie’ equivalent equipment close to electrosurgical or any
other medical electrical equipment.
4.53 To minimize the possibility of electrical interference

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.
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 SLead 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.
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.

frequencies for each of the three output groups (bipolar,
monopolar cut and monopolar coag) as detailed in the
‘Technical data’ section.
If a monopolar user activates power at the same time
(but after) a bipolar user the tone will continue at the
bipolar frequency until the bipolar user stops activation
when the monopolar user’s frequency will start

unit). If the monopolar user only activates the unit for
a short period during a long activation by the bipolar
user then the monopolar user’s frequency will not be

2) During surgery, when an active electrode
is not in use, it should always be put in an
electrosurgical quiver or similar receptacle.
This is most important when both bipolar and
monopolar electrodes are required for the same
surgical procedure.

WARNINGS
1) Footswitches should be used with care at
all times and should always be under control
of the surgeon or designated assistant, as
inadvertent operation could have serious
results.
2) Footswitches should be kept clear of areas
where other personnel could accidentally press
them, also ensure that they do not get wedged
under theatre equipment.

especially flexible endoscopes. Most urological
endoscopes are suitable for spray coag. If in doubt check
that the voltage rating of the laparoscopic or endoscopic
instrument is at least as high as the maximum spray coag
open circuit voltage of this electrosurgical unit (see
Technical Date section).
CAUTION
Although power output in the spray mode is
lower than in the pinpoint mode (79W rather
than 170W maximum), the effect on tissue is
much greater in the spray mode. Until
experience is gained, only low control settings
should be used.

5.34 'Running' tones are generated whenever monopolar
cut or coag outputs are activated by footswitch or
fingerswitch. The volume of the running tones is adjustable
by the volume control (33) on the back of the unit. A small
screwdriver is needed for this adjustment. This does not
affect the pitch (i.e. frequency) of the tones.

output is only obtained by pressing the yellow (cut)
fingerswitch button, or by pressing the yellow (cut)
footswitch.
WARNING
Apparent low power or failure of the unit to
function correctly at the normal operating
settings may indicate faulty application of the
plate electrode or poor contact in its
connections. In this case, the application of the
plate electrode and its connections should be
checked before selecting a higher output
power.
5.40 The output power level is adjusted by the power output
controls (14) and (21) for cut and coag modes respectively.

display range selection button (35) on the rear of the unit.
5.38 The two coag modes are selected by touch buttons The two available digital displays are as follows:
(19) pinpoint coag and (20) spray coag. The pinpoint mode
provides low voltage coagulation for most types of surgery.
The spray coag mode activates a separate generator circuit
which provides a waveform that reduces the cutting effect
to a very low level but provides fast coagulation by allowing
an arc to form between the electrode and the tissue. The
waveform is a series of high energy single pulses. Spray
coag allows non-contact coagulation of tissue that tends
to adhere to active electrodes.
Note: Spray coag (indicated with the bright green LED) is
not recommended for laparoscopic and endoscopic
procedures where its high voltage waveform can damage
the insulation of laparoscopic and endoscopic instruments,

unplug the bipolar cable from the unit, change the forceps,
then plug the bipolar cable back into the unit.
Footswitches
5.49 Set power output control (1) to the required level.
Note that the digital power display (6) shows the typical
available output power for either power range. (see 5.41
for range control selection).
5.50 Activation of the connected footswitch will turn on
the power for as long as the footswitch is depressed.
Notes:
♦ Blue power activated indicator (7) will come ‘on’ and
the running tone will sound only when the output is
activated (see 5.34 for adjustment of volume).
♦
The 15W (micro) range should be used initially if the
power level required is not known.
♦
The method of ‘constant amplitude’ power control
provides very effective coagulation at low power
levels.

♦
Set power output control (1) to ‘minimum’.
(see section 3)
5.47 The bipolar mode is extremely safe, but it is always
good practice to start at a low setting and increase slowly
until the required effect is obtained. Bipolar coagulation of
most blood vessels is normally self-terminating because
the rapid rise in tissue resistance, brought about by
coagulation, limits the flow of current. An audible ‘pop’
can result from the rapid boiling of liquids in the tissue.
E-IM54f

5.54 The best results are obtained by varying the setting
rather than having a predetermined value for all uses. It
must be noted that digital power displays, only display the
typical available power for a given control setting. This is
proved by the fact that the displayed value does not change
between the active electrode being out of contact with the
tissue (zero power) or deeply embedded in well perfused
flesh (near maximum power delivered).
P21/37
5.55 The output control settings required for a particular
surgical procedure are also dependent on a number of
external factors (type of tissue, speed at which the surgeon
works, type of electrode in use, area of forcep tips in
contact). Therefore the recommended settings given in
Table 1 are for guidance only.
Alarms
5.57 If more than one output demand is received at the
same time (such as two footswitches or a footswitch and a
fingerswitch button being pressed) the unit will produce
an alarm indication and no power output. This is an
important safety feature and applies to any combination of
footswitch and fingerswitch for monopolar USER 1, or for
USER 2 or for bipolar.

Notes:
♦
Monopolar blend output mode can be used with advantage in many cutting procedures, particularly when only
a single (yellow) footswitch is being used.
♦
The blend mode produces less output power for a given control setting than normal cut, as shown on digital
power display (8 of illustration 11).
