Monopolar Modes

The system produces six modes of monopolar power output.

Precaution

To provide expected functionality from a hand piece, proper insertion is required. Refer to the alignments dots below the receptacles for proper insertion orientation.

CUT Modes

PURE CUT provides a clean, precise cut in any tissue with little or no hemostasis.

BLEND CUT is a conventional blended waveform that provides slower cutting with

simultaneous hemostasis.

VALLEYLAB Mode

VALLEYLAB mode is a unique combination of hemostasis and dissection that allows the

user to slow down for more hemostasis and speed up for faster dissection.

COAG Modes

SOFT desiccates tissue at a relatively slower rate with deeper thermal penetration. It is

typically performed with a ball electrode.

FULGURATE coagulates tissue by sparking from the active electrode, through air, to the patient tissue.

SPRAY delivers wider fulguration; penetration is shallower and the affected tissue area is larger than with the FULGURATE mode.

SHARED allows two monopolar instruments to activate simultaneously in either FULGURATE or SPRAY modes. A single power setting is provided and power is shared between the two instruments.

Note: SOFT and SHARED COAG modes are features that are not available on the clinical screen until they have been enabled. These features can be enabled through the Feature Enabling menu of the service screen. See Feature Enabling Menu on page 3-10.

Auto Bipolar

The Auto Bipolar feature senses tissue impedance between the two bipolar electrodes,
then uses the impedance information to automatically start or stop bipolar RF energy
delivery. Optionally, the user may select a timed activation delay for auto start of RF
activation.

Note: When using Auto Bipolar, the tissue in the grasp of the bipolar device must have an
impedance less than 2200 . The activation impedance safety feature will not deliver RF
power to the tissue if it is not within the specified range. This is a factory-set value that
cannot be reset by the user.

Note: Auto Bipolar is a feature that is not available on the clinical screen until it is enabled. This feature can be enabled through the Feature Enabling Menu of the service screen. See Feature Enabling Menu on page 3-10.

Important

If the VLFT10ADP1 Bipolar Adapter is used, only one bipolar instrument can set the Auto Bipolar feature to ON.

Warnings and Precautions for Patient and Operating Room Safety

The safe and effective use of electrosurgery depends to a large degree upon
factors solely under the control of the operator. There is no substitute for a
properly trained and vigilant surgical team. It is important that the operating
instructions supplied with this or any electrosurgical equipment be read,
understood, and followed.

Electrosurgery has been used safely in millions of procedures. Before starting any
surgical procedure, the surgeon should be trained in the particular technique and
surgical procedure to be performed, should be familiar with the medical literature
related to the procedure and potential complications, and should be familiar with
the risks versus the benefits of utilizing electrosurgery in the procedure.

Use of electrosurgery in O
to reduce the O

If possible, stop supplemental oxygen at least one minute before and during use of electrosurgery.

The use of non-flammable agents is recommended for cleaning and disinfecting wherever possible. If flammable agents are used, do not activate the energy platform until flammable vapors from skin-preparation solutions and tinctures have dissipated.

There is a risk of pooling of flammable solutions under the patient or in body depressions, such as the umbilicus, and in body cavities, such as the vagina. Any fluid pooled in these areas should removed before activating the energy platform.

Avoid the accumulation of naturally occurring flammable gases that may accumulate in body cavities such as the bowel.

Prevent the accumulation of flammable or oxidizing gases or vapors under surgical drapes or near the surgical site.

Tissue buildup (eschar) on the tip of an active electrode may create embers that pose a fire hazard, especially in oxygen-enriched environments. Keep the electrode clean and free of all debris.

Facial and other body hair is flammable. Water soluble surgical lubricating jelly may be used to cover hair close to the surgical site to decrease flammability.

Verify that all anesthesia circuit connections are leak free before and during use of electrosurgery.

Do not touch the patient while touching a connector or fuse contact at the same time. Simultaneous contact can cause electric shock or burns.

Do not wrap the instrument cords or patient-return-electrode cords around metal objects. This may induce currents (capacitive coupling) that could lead to shocks, fires, or injury to the patient or surgical team.

Electric Shock Hazard Do not connect wet instruments to the energy platform. Ensure that all instruments and adapters are correctly connected and that no metal is exposed at any connection points.

Confirm proper power settings before proceeding with surgery. If the proper power settings are
not known, set the power to a low setting and cautiously increase the power until the desired
effect is achieved. If increased power settings are requested, check the patient return electrode and
all instrument connections before major power-setting adjustments.

Safety

Contact between the active electrode and any metal will greatly increase current flow and can result in unintended surgical effect.

Valleylab FT10 Energy Platform Service Manual 2-3

General Warnings and Precautions

Warning

While using electrosurgery, the user and patient should not be allowed to come into direct contact
with grounded metal objects (e.g., surgical-table frame, instrument table, etc.). If this is not
possible during certain procedures (e.g., those in which noninsulated head frames are used), use
extreme caution to maximize patient safety:

• Use the lowest power setting that achieves the desired effect.

• Place the patient return electrode as close to the surgical site as possible.

• Place dry gauze between the patient and the grounded object if possible.

• Continually monitor the contact point(s).

• Do not use metal needle monitoring electrodes.

Warning

Ensure the UFP connector is fully inserted in the generator prior to use. A partially inserted connector may result in injury to the surgical team if the exposed connector is touched during use.

Precaution

Read the instructions, warnings, and precautions provided with this energy platform and associated accessories before using. Specific instructions for electrosurgical instruments are not included in this manual.

Read the instructions, warnings, and precautions provided with electrosurgical instruments before using. Specific instructions for electrosurgical instruments are not included in this manual.

Always use the lowest power setting that achieves the desired surgical effect. The active electrode
should be utilized only for the minimum time necessary in order to lessen the possibility of
unintended burn injury. Accidental and unintended burn injury has occurred during procedures in
small surgical fields and on small appendages. Pediatric applications and/or procedures performed
on small anatomic structures may require reduced power settings. The higher the current flow and
the longer the current is applied, the greater the possibility of unintended thermal damage to
tissue, especially during use on small structures.

Certain devices or accessories may present an unacceptable risk at low power settings. For
example, with argon beam coagulation, the risk of gas embolism increases if there is insufficient
high frequency (HF) power to produce a rapid, impermeable eschar on the target tissue.

For surgical procedures where the current could flow through delicate parts of the body, the use of bipolar techniques may be desirable in order to avoid unwanted coagulation.

Connect only Covidien-approved devices. Using devices from other manufacturers may cause equipment malfunction or patient injury.

Examine all instruments and connections to the system before using. Improper connection may result in arcs, sparks, instrument malfunction, or unintended surgical effects.

Do not operate the generator for clinical use while cables are connected to the utility WiFi
receptacle or Ethernet receptacles on the back of the generator. This may cause a system error that
would halt the procedure and require restarting the generator.

2-4 Valleylab FT10 Energy Platform Service Manual

General Warnings and Precautions

Precaution

Do not turn the activation tone down to an inaudible level. The activation tone alerts the surgical team when the energy platform is delivering RF energy.

When using a smoke evacuator in conjunction with the VLFT10GEN, set the system volume control at a level that ensures the activation tones can be heard.

A non-functioning VLFT10GEN may cause an interruption of surgery. A backup system should be available for use.

Inadvertent activation may occur while installing, removing, or bending electrodes. Ensure that the instrument cord is not connected to the VLFT10GEN or that the system is off.

Leads connected to the patient should be positioned in such a way that contact with the patient
or other leads is avoided because the capacitance between the electrode cable and the patient may
result in some local high current densities. When not in use, place electrosurgical instruments in a
safety holster or safely away from patients, the surgical team, and flammable materials.

Warnings and Precautions for

Patient and Operating Room

Safety

Studies have shown that smoke generated during electrosurgical procedures can be potentially harmful to patients and the surgical team. These studies recommend adequately ventilating the smoke by using a surgical-smoke evacuator or other means.

Publication No. 96-128, September, 1996

Notice

Connect the power cord to a properly grounded power receptacle having the correct voltage. Otherwise, product damage may result.

The VLFT10GEN requires special precautions regarding EMC and needs to be installed and put into service according to the EMC information provided in Chapter 4, Technical Specifications.

Portable and mobile RF communications equipment can affect the VLFT10GEN. Refer to the EMC information provided in Chapter 4, Technical Specifications.

The system should not be used adjacent to or stacked with equipment other than specified in the Valleylab FT10 Energy Platform User Guide and Service Manual. If adjacent or stacked use is necessary, the system should be observed to verify normal operation in the configuration in which it will be used.

The system intentionally applies RF energy for diagnosis or treatment during activation. Observe
other electronic medical equipment in the vicinity during the system activation for any possible
adverse electromagnetic effects. Ensure adequate separation of electronic medical equipment
based on observed reactions.

1

The use of accessories, other than specified in the Valleylab FT10 Energy Platform User Guide and Service Manual, may result in increased emissions or decreased immunity of the system.

Before plugging the generator into a power receptacle, verify that the installed fuses are appropriate for the local input line voltage. See Input Power on page 4-3.

Valleylab FT10 Energy Platform Service Manual 2-5

General Warnings and Precautions

Notice

Calibration must be performed on a non-conductive surface. Do not use antistatic bench-top mats. When performed on a conductive surface, calibration values may not be accurate.

After completing calibration, the system will reboot to the clinical screen to save the values or abort the calibration.

Important

The VLFT10GEN is intended for use in a hospital or medical center environment.

If required by local codes, connect the energy platform to the hospital potential equalization system with an equipotential cable.

The operator of the generator may be as far away from the generator as 2 feet (direct product interaction), 5 feet (inside the sterile field), and 13 feet (across the room working with other equipment).

RFID and WiFi function may be interfered with by other equipment even if that other equipment complies with CISPR emission requirements.

Log files are maintained when the system is powered down. The time when the system was powered down or experiences a total loss of power is also logged.

When log files reach capacity, the earliest log is deleted to make room for the newest log.

Generator log files can be uploaded for viewing on a computer using Valleylab Exchange. Refer to the Valleylab Exchange Remote Software System User’s Guide available at http://www.medtronic.com/covidien/support/valleylab-exchange.

The VLFT10GEN contains substances of very high concern as defined in Article 57 and Annex XIV
of Regulation (EC) No 1907/2006 (Registration, Evaluation, Authorization, and Restriction of
Chemicals [REACH]). Specifically, it contains di-(2-ethylhexyl)phthalate (DEHP)
(CAS number 117-81-7; EC number EN 204-211-0) and 1,2 dimethoxyethane, ethylene glycol
dimethyl ether (EGDME) (CAS number 110-71-4; EC number EN 203-794-9) in concentrations
above 0.1% by weight.

Warnings and Precautions for the Energy Platform

Warning

Each instrument receptacle on this energy platform is designed to accept only one instrument at a time. Follow the instructions provided with electrosurgical instruments for proper connection and use.

Failure of the generator could result in an unintended increase of output power or activation.

Only medical devices compliant with IEC 60601-1 may be connected to the external system receptacles. The use of any external system connected to the VLFT10GEN should be evaluated by qualified personnel.

2-6 Valleylab FT10 Energy Platform Service Manual

General Warnings and Precautions

Precaution

Do not stack equipment on top of the energy platform or place the energy platform on top of electrical equipment. This is an unstable configuration and does not allow for adequate cooling.

Provide at least 4” to 6“ (10 to 15 cm) of unobstructed space round the top and sides of the generator to ensure proper cooling.

Provide as much distance as possible between the energy platform and other electronic equipment (such as monitors). Do not cross or bundle cords from electronic devices. This energy platform may cause interference with other electronic equipment.

The use of monitoring systems that incorporate high-frequency current-limiting devices is recommended to reduce interference with the monitoring device.

Warnings and Precautions for

Patient and Operating Room

The system contains electrostatic-sensitive components. When repairing the system, work at a
static-control workstation. Wear a grounding strap when handling electrostatic-sensitive
components, except when working on an energized system. Handle Printed Circuit Board
Assemblies (PCBA) by their non-conductive edges. Use an antistatic container for transport of
electrostatic-sensitive components and PCBAs.

Notice

Make no modifications to the electrosurgical generator. Any modifications to the system will void the warranty.

When testing RF equipment, follow these test procedures. Keep test leads to the minimum length
usable; lead inductance and stray capacitance can adversely affect readings. Carefully select
suitable ground points to avoid ground loop error in measurements.

The accuracy of most RF instruments is approximately 1%–5% of full scale. Using uncompensated scope probes causes large errors when measuring high-voltage RF waveforms.

Warnings and Precautions for Active Instruments

Warning

Energy applied to an electrosurgical instrument can convert liquids to steam. The thermal energy
of steam may cause unintended injury in close proximity to the tip of the instrument. Care should
be taken in surgical procedures occurring in confined spaces in anticipation of this possibility.

Safety

Do not activate the energy platform in an open-circuit condition. To reduce the chances of unintended burns, activate the energy platform only when the active electrode is near or touching the target tissue.

Use the lowest power setting that achieves the desired surgical effect and use a low-voltage waveform (PURE CUT, BLEND, or VALLEYLAB mode) to lessen the potential for the creation of capacitive currents.

If energy delivery from the generator cannot be stopped, remove the handpiece from the patient and disconnect the handpiece or power cord.

Valleylab FT10 Energy Platform Service Manual 2-7

General Warnings and Precautions

Warning

Do not activate the instrument when not in contact with target tissue as this may cause injuries due to capacitive coupling.

The surface of the active electrode may remain hot enough to cause burns after the RF current is deactivated.

Keep the active electrodes clear. Build-up of eschar may reduce the instrument's effectiveness. Do not activate the instrument while cleaning. Injury to operating room personnel may result.

Precaution

Read the instructions, warnings, and precautions provided with electrosurgical instruments before using. Specific instructions for electrosurgical instruments are not included in this manual.

Inspect instruments and cords—especially for laparoscopic/endoscopic instruments—for breaks,
cracks, nicks, and other damage before every use. If damaged, do not use. Damaged instruments
or cords may result in injury or electrical shock to the patient or surgical team.

Use only instruments that can withstand the maximum output (peak) voltage for each output
mode as listed in Chapter 4, Technical Specifications. Using an instrument with a voltage rating
that is lower than the maximum output voltage may result in injury to the patient or the operator,
or damage to the instrument.

Information on voltage ratings for non-Covidien instruments should be obtained from the instrument’s manufacturer.

Notice

All Covidien instruments have voltage ratings that are greater than the maximum output voltages in the VLFT10GEN.

Inspect instrument plugs for wear before every use. Worn plugs may result in a loose or stuck connection to the generator.

Warnings for Implanted Electronic Devices (IEDs)

IEDs include, but are not limited to, pacemakers, neurostimulators, implantable cardioverter defibrillators (ICDs), ventricular assist devices (VAD), spinal cord stimulators, cochlear implants, infusion pumps, and bone growth stimulators.

Warning

Use the system with caution in the presence of internal or external pacemakers or other implanted
devices. Interference produced by electrosurgical equipment can cause a pacemaker or other
device to enter an unsafe mode or permanently damage the device. Consult the device
manufacturer or responsible hospital department for further information when use is planned in
patients with implanted medical devices.

2-8 Valleylab FT10 Energy Platform Service Manual

Warnings and Precautions for Monopolar Procedures

Post Surgery Safety Issues

Warning

Shock Hazard Before cleaning or servicing the unit, disconnect the power plug from the power

outlet in order to completely isolate the generator from mains power.

Notice

Do not clean the energy platform with abrasive cleaning or disinfectant compounds, solvents, or other materials that could scratch the panels or damage the energy platform.

Warnings and Precautions for

Patient and Operating Room

Warnings and Precautions for Monopolar Procedures

Warning

Simultaneously activating suction/irrigation and electrosurgical current may result in increased arcing at the electrode tip, burns to unintended tissues, or shocks and burns to the surgical team.

Power output of a two- or three-button pencil (COAG selection) can change during use when another monopolar instrument is activated.

Some surgeons may elect to “buzz the hemostat” during surgical procedures. It is not
recommended, and the hazards of such a practice probably cannot be eliminated. Burns to the
surgeon’s hands are possible. To minimize the risk take these precautions:

• Do not buzz the hemostat with a needle electrode.

• Do not lean on the patient, the table, or the retractors while buzzing the hemostat.

• Activate CUT rather than COAG. CUT has a lower voltage than COAG.

• Firmly grasp as much of the hemostat as possible before activating the energy platform. This disperses the current over a larger area and minimizes the current concentration at the finger tips.

• Buzz the hemostat below hand level (as close as possible to the patient) to reduce the opportunity for current to follow alternate paths through the surgeon’s hands.

Safety

• Use the lowest power setting possible for the minimum time necessary to achieve hemostasis.

• Activate the energy platform after the instrument makes contact with the hemostat. Do not arc to the hemostat.

• When using a coated- or nonstick-blade electrode, place the edge of the electrode against the hemostat or other metal instrument.

DEMO mode delivers monopolar energy without the use of a patient return electrode, and is intended for demonstration purposes only. Chance of burns to the patient significantly increase when DEMO mode is used for clinical procedures.

Valleylab FT10 Energy Platform Service Manual 2-9

Warnings and Precautions for Monopolar Procedures

Precaution

To provide expected functionality from a hand piece, proper insertion is required. Refer to the alignment dots below the receptacles for proper insertion orientation.

The use of modes that produce electrical arcs between the active electrode and tissue may result in neuromuscular stimulation.

Warnings and Precautions for Patient Return Electrodes

Warning

It is not possible to foresee what combination of current and duty cycle may be safely used in every
situation—for example, when higher currents and/or longer duty cycles are used on procedures
such as tissue lesioning, tissue ablation, tissue vaporization; and procedures where conductive fluid
is introduced into the surgical site. Under these conditions a greater risk may exist that the heating
under a fully applied return electrode may be high enough to injure the patient.

When using a Covidien energy platform or a patient return electrode during these types of surgical
procedures, the user should seek written guidance in the form of detailed user instructions from
the manufacturer of the active accessory regarding the currents and duty cycles that can be
expected. In some instances, the application of additional patient return electrodes may help
mitigate the increased risk.

Do not attempt to use patient return electrodes that disable the Return Electrode Monitoring (REM)
system. The VLFT10GEN REM system will function correctly only with contact quality monitoring
(CQM) split-style patient return electrodes. Other patient-return-electrode products may not
identify loss of safe contact between the return electrode and the patient, thereby failing to
provide an auditory alarm and causing patient injury or product damage.

The safe use of monopolar electrosurgery requires proper placement of the patient return electrode. To avoid electrosurgical burns beneath the patient return electrode, follow all directions provided with the product.

Do not cut a patient return electrode to reduce its size. Patient burns due to high current density may result.

To avoid patient burns, ensure that the patient return electrode makes firm and complete contact
with the skin. Always check the patient return electrode periodically, after the patient is
repositioned, and during procedures involving long periods of activation.

Use of duty cycles greater than 25% (10 seconds active followed by 30 seconds inactive) will
increase the risk that heat build-up under a return electrode may be high enough to injure the
patient. Do not continuously activate for longer than one minute.

Apparent low-power output at the normal operating settings may indicate faulty application of the
return electrode. Verify the return electrode is correctly placed and attached to the patient as
described in the electrode’s instructions for use. Verify the connection between the electrode and
the generator before selecting a higher output power.

2-10 Valleylab FT10 Energy Platform Service Manual

Warnings and Precautions for Monopolar Procedures

Warning

DEMO mode does not monitor the quality of pad contact with the patient. No warning will be issued from the generator when a non-REM return electrode’s pad-to-patient contact degrades when in DEMO mode.

Precaution

Covidien REM Polyhesive patient return electrodes are recommended for use with the VLFT10GEN. Return electrodes from other manufacturers may not provide proper impedance to work correctly with the energy platform.

Important

A statement of compatibility from the CQM patient return electrode manufacturer should be obtained prior to the use of a non-Covidien CQM patient return electrode.

A patient return electrode is not necessary in bipolar or LigaSure procedures.

Warnings and Precautions for

Patient and Operating Room

Safety

Inadvertent Radio Frequency (RF) Burns

Warning

Electrodes and probes used with monitoring, stimulation, and imaging devices (or similar equipment) can provide a path for high frequency current even if the electrodes or probes are isolated at 50 –60 Hz, insulated, and/or battery operated.

Do not use needles as monitoring electrodes during electrosurgical procedures. Inadvertent electrosurgical burns may result.

To reduce the risk of an inadvertent electrosurgical burn at the monitoring electrode or probe site,
place the electrode and/or probe as far away as possible from the electrosurgical site and/or patient
return electrode. Protective impedances (resistors or RF inductors) installed in the monitoring leads
may reduce the risk of such burns. Consult the hospital biomedical engineer for further
information.

Valleylab FT10 Energy Platform Service Manual 2-11

Warnings and Precautions for Monopolar Procedures

Warning

In some circumstances, the potential exists for alternate site burns at points of skin contact (e.g.,
between the arm and the side of the body). This occurs when electrosurgical current seeks a path
to the patient return electrode that includes the skin-to-skin contact point. Current passing
through small skin-to-skin contact points is concentrated and may cause a burn. This is true for
ground referenced and isolated output electrosurgical energy systems.

To reduce the potential for alternate site burns, do one or more of the following:

• Avoid skin-to-skin contact points, such as fingers touching leg or knee touching knee when positioning the patient.

• Place insulation, such as dry gauze or towel, between contact points to ensure that contact does not occur.

• Position the patient return electrode to provide a direct current route between the surgical site and the return electrode which avoids skin-to-skin contact areas.

• In addition, place patient return electrodes according to the manufacturer’s instructions.

2-12 Valleylab FT10 Energy Platform Service Manual

Warnings and Cautions for Laparoscopic Procedures

Warnings and Cautions for Laparoscopic Procedures

Warning

For laparoscopic procedures, be alert to these potential hazards:

• Laparoscopic surgery may result in gas embolism due to insufflation of gas in the abdomen.

• The electrode tip or LigaSure jaws may remain hot enough to cause burns after the electrosurgical current is deactivated.

• Inadvertent activation or movement of the activated instrument electrode or jaws outside of the field of vision may result in injury to the patient.

• Localized burns to the patient or physician may result from electrical currents carried through
conductive objects (such as other instrument, cannulas, or scopes). Electrical current may be
generated in conductive objects through direct contact with the active electrode or jaws,
capacitative coupling, or by the active instrument (electrode or cable) being in close proximity
to the conductive object.

• Do not use hybrid trocars that have a non-conductive locking anchor placed over a conductive
sleeve. For the operative channel, use all-metal or all-plastic systems. At no time should
electrical energy pass through hybrid systems. Capacitive coupling of RF current may cause
unintended burns.

• When using laparoscopic instrumentation with metal cannulas, the potential exists for burns
to the abdominal wall due to direct electrode contact or capacitive coupling of RF current. This
is most likely to occur in instances where the energy platform is activated for extended periods
at high power levels inducing high current levels in the cannula.

• Carefully insert and withdraw LigaSure instruments from cannulas to avoid possible damage to the devices and/or injury to the patient.

• Ensure that the insulation of single-use and reusable laparoscopic instrumentation is intact and
uncompromised. Compromised insulation may lead to inadvertent metal-to-metal sparking
and neuromuscular stimulation and/or inadvertent sparking to adjacent tissue.

Warnings and Precautions for

Patient and Operating Room

Safety

• Do not activate the LigaSure function in an open-circuit condition. Activate the energy platform only when the instrument is near or in direct contact with the target tissue to reduce the possibility of unintended burns.

Covidien recommends against the use of laparoscopic surgery on pregnant patients.

Valleylab FT10 Energy Platform Service Manual 2-13

Warnings and Precautions for Bipolar Procedures

Warnings and Precautions for Bipolar Procedures

Warning

Use of different Covidien cord models or cords from other manufacturers may not achieve proper
electrical output for this device, thereby failing to produce the desired clinical effect. For example,
Auto Bipolar activation/deactivation settings may not work properly using cords other than those
specified by Covidien.

In the Auto Bipolar setting, activation may occur with contact of any material. When not in use, place electrosurgical instruments in a safety holster or safely away from patients, the surgical team, and flammable materials.

Precaution

Bipolar instruments must be connected to the Bipolar instrument receptacle only. Improper connection may result in inadvertent system activation.

Do not use instruments with flying leads with the VLFT10GEN.

Do not use the FT0501 ForceTriad Bipolar Adapter with the VLFT10GEN.

Bipolar forceps should not be set down while Auto Bipolar is active. Contact with any material may cause activation. Turn off Auto Bipolar before setting down an instrument.

Warnings and Precautions for LigaSure Procedures

Warning

LigaSure instruments are intended for use only with compatible Covidien generators and energy
platforms. See the front cover of the instrument’s instructions for a list of compatible generators.
Use of these instruments with other generators may not result in electrical output that they were
designed for, and may not result in the desired clinical effect.

The tissue fusion function has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use this function for these procedures.

Tissue fusion requires the application of RF energy and pressure from the instrument. Ensure
grasping pressure is maintained until the seal cycle is complete.Tissue to be sealed must be firmly
grasped between the instrument jaw electrodes. Tissue in the jaw hinge or outside the instrument
jaw may not be sealed even if thermal blanching occurs.

If the seal-cycle-complete tone has not sounded, an optimal seal may not have been achieved. Reactivate the RF energy until a seal-cycle-complete tone is heard.

Do not activate the energy platform until the tissue-fusion or LigaSure instrument has been applied
with the proper pressure. Do not release the pressure on the tissue until the end tone has sounded.
Activating the energy platform with improper grasping pressure applied may result in an improper
seal and may increase thermal spread to tissue outside the surgical site.

2-14 Valleylab FT10 Energy Platform Service Manual

Warning

Fluid in the body cavity should be kept to a minimum during treatment. Conductive fluids (e.g.,
blood or saline) in direct contact with, or in close proximity to, the instrument may carry electrical
current or heat, which may cause unintended burns to the patient. Aspirate fluid from around the
instrument jaws before activating the instrument.

Do not attempt to seal or cut over clips or staples as incomplete seals may be formed.

Servicing

Precaution

Energy-based devices, such as electrosurgical pencils or ultrasonic scalpels, that are associated with thermal spread should not be used to transect seals.

Warnings and Precautions for Bipolar Resection

Warning

Bipolar Resection mode is intended to be used only with compatible resectoscopes for endoscopically controlled removal (resection) or coagulation of tissue using 0.9% NaCI solution (saline) as the irrigation medium

Precaution

Bipolar Resection mode is supported only if a Covidien-specified bipolar resection instrument is
connected to the LigaSure/Bipolar receptacle with a Covidien bipolar resection cord. In addition,
Bipolar Resection mode can be activated only with the Covidien Bipolar Resection foot pedal
connected to the LigaSure/Bipolar foot-pedal receptacle. See the cords IFU listed in Accessories on
page 1-11 for the list of supported bipolar resection instruments and cords.

Servicing

Warnings and Precautions for

Patient and Operating Room

Safety

Warning

Electric Shock Hazard Do not remove the energy platform cover. Contact qualified personnel for

service.

Do not dispose of electrical appliances as unsorted municipal waste. Use separate collection facilities.

Electrical appliances that are incorrectly disposed in dumps or landfills can leach dangerous substances causing contamination of soil and groundwater, and damaging the environment.

Contact your local government, or point of sale for information regarding the collection of waste electrical appliances

• International: 1 303 476 7996

Shunt Cords

Warning

Some surgical instruments (e.g., colonoscopes) may allow substantial leakage current that could
burn the surgeon. If the instrument manufacturer recommends the use of a shunt cord (s-cord) to
direct the current back to the energy platform, an E0507-B adaptor must also be used. To avoid a
REM alarm, a REM Polyhesive patient return electrode with the E0507-B adaptor must be used.

Conductive Fluid In the Surgical Site

Warning

When this energy platform is used in monopolar procedures where conductive fluid (including, but
not limited to saline or lactated Ringer’s) is introduced into the surgical site for distention or to
conduct RF current, higher than normal currents (greater than one amp) may be produced. In this
situation, use one or more adult-size return electrode. Do not use return electrodes labeled for
children, infants, babies, neonatal use, or pediatric use.

Use of duty cycles greater than 25% (10 seconds active followed by 30 seconds inactive) will
increase the risk that heat build-up under a return electrode may be high enough to injure the
patient. Do not continuously activate for longer than one minute.

Electronic Assemblies Principles of Operation

Electronic Assemblies Principles of Operation

High-Voltage/Low-Voltage Power Supply Principles of Operation

The High-Voltage/Low-Voltage power-supply module provides a complete main power supply solution. It is contained within its own chassis and is cooled by a dedicated system fan.

Controller PCBA

The Controller Printed Circuit Board Assembly (PCBA) serves as the main digital control of the system. It comprises the following features:

• Control of the user interface (touchscreen, push-button, foot pedal, and handpiece activation inputs, LCD, and LEDs)

• Closed-loop control of RF power delivery

• External communications (WiFi and Ethernet)

• Control of smoke-evacuation devices or blanking functionality of an EKG device

• Audio control

• Power-supply control

RF PCBA

The RF PCBA serves primarily to convert a DC voltage sourced from the High Voltage
Power supply output to a 434 kHz AC source with an output impedance that is tailored
to match the energy modality being sourced. The RF PCBA also houses the RF energy
current and voltage sensors which are used to provide closed loop control of the energy
delivered to the patient.

Steering Relay PCBA

The Steering Relay PCBA accepts energy from the RF PCBA and directs it toward the
intended energy-output receptacle based on energy modality. Non-activated energy
receptacles are disconnected from the energy source by way of high-voltage relays. The
Steering Relay PCBA houses the REM module, the ISOFirm modules, and the isolated
power supply for the REM and ISOFirm modules.

Display PCBA

The Display PCBA houses the touchscreen controller, the LCD backlight driver, and provides an interface for the LCD, VIBE module, and User Interface buttons.

3-4 Valleylab FT10 Energy Platform Service Manual

Mechanical Assemblies Principles of Operation

Mechanical Assemblies Principles of Operation

The Chassis assembly consists of 4 major metal mechanical subassemblies (front bezel,
chassis base, chassis top, and rear bezel), 3 cooling fans, and a molded foam PCBA
mounting structure (Electronic Packaging Assembly Concept—E-PAC™*).

IT Network Connectivity Principles of Operation

The generator connects to an IT network, usually through Valleylab Exchange, for the
purpose of registering the generator and its components, updating software, setting the
country code, and transmitting error and event logs. The generator cannot connect to an
IT network while in clinical mode. Because the generator cannot connect to an IT network
while in clinical mode, there are no OR-related hazardous situations. The generator has to
be in the service screens for IT network connectivity. The generator can be 1) connected
to another computer (point to point connection), 2) connected remotely to a router or to
a DHCP server via a WiFi access point broadcasting a non-hidden SSID, or 3) connected via
Ethernet cable to a router or directly to the DHCP server. The generator allows wired
connections to be either static (assigned by the user) or assigned by the DHCP server. The
MAC address is unique to each generator.

Connection of the generator to an IT network that includes other equipment could result

Energy Output Characteristics

The VLFT10GEN automatically senses the tissue resistance and adjusts the output voltage
to maintain a consistent effect across different tissue density. The adjustment is based on
the selected mode or effect, power setting, and the level of tissue resistance. The
maximum output voltage is controlled to reduce capacitive coupling and video
interference and to minimize undesired sparking. The following table outlines the rated
power, peak voltages, and maximum output current for a given modality. The peak voltage
includes tolerance and identifies the maximum value across all loading conditions. Output
power can vary ± 15%. Current nominal maximum does not include tolerance.

1. Per IEC 60601-2-2: 2009 clause 201.7.9.2.2.101(c)(2), whenever the peak voltage is greater than 1600 V, the calculated variable y is less than the actual crest factor. The peak voltage at rated load can be calculated using the equation: V

peak(Umax

) = TypicalCrestFactor √Power·RatedLoad

2. At rated load.

3. Bipolar Resection CUT maximum power is 432 W, including tolerance.

4. Rated load in SHARED COAG modes is the total energy channel load. For SHARED dual

activation using two activating instruments, it is the parallel combination of the two loads. For
SHARED single activation using one activating instrument, it is the load connected to the
activating electrode only.

TissueFect Tissue Sensing Technology, an automatic adjustment, controls all modes and
effects. As tissue resistance increases from zero, the energy platform outputs constant
current, followed by constant power, followed by constant voltage. The maximum output
voltage is controlled to reduce capacitive coupling and video interference and to minimize
sparking.
