Valleylab stresses safety in the use and servicing of its

electrosurgical equipment. This chapter presents the following:

CHAPTER

• Safety information

• Warnings, Cautions, and Notices

Refer to the Preface, Conventions Used In This Guide, for further

information on Warnings, Cautions, and Notices.

LigaSure Vessel Sealing Generator Service Manual 1-1

Safety Information

Safety Information

The safe and effective servicing of electrosurgical equipment depends to a large
degree on factors solely under the control of the service person. There is no
substitute for a properly trained and vigilant service staff.

Warnings, Cautions, and Notices

Before servicing the generator, it is important that you read, understand, and
follow the instructions supplied with it and with any other equipment used to
install, test, adjust, or repair the generator.

General

Warning

Use the generator only if the self-test has been completed as described.
Otherwise, inaccurate power outputs may result.

The instrument receptacles on this generator incorporate a smart interface. They
operate with Valleylab LigaSure handsets or smart connector adapters exhibiting
smart codes.

Caution

Do not stack equipment on top of the generator or place the generator on top of
electrical equipment. These configurations are unstable and/or do not allow for
adequate cooling.

Provide as much distance as possible between the electrosurgical generator and
other electronic equipment (such as monitors). An activated electrosurgical
generator may cause interference with them.

Do not turn the activation tone down to an inaudible level. The activation tone
alerts the surgical team when an accessory is active.

Notice

If required by local codes, connect the generator to the hospital equalization
connector with an equipotential cable.

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

1-2 LigaSure Vessel Sealing Generator Service Manual

Warnings, Cautions, and Notices

Active Accessories

Warning

Electric Shock Hazard Do not connect wet accessories to the generator.

Electric Shock Hazard Ensure that all accessories and adapters are correctly

connected and that no metal is exposed.

Caution

Connect accessories to the proper receptacle type. In particular, connect bipolar
accessories to the bipolar instrument receptacle only. Connect vessel sealing
accessories to the LigaSure seal receptacle only.

Notice

Do not activate the generator until the forceps have made contact with the
patient. Product damage may occur.

Fire/Explosion Hazards

Warning

Danger: Explosion Hazard Do not use the generator in the presence of

flammable anesthetics, gases, liquids, or objects.

Service Personnel Safety

Fire Hazard Do not place active accessories near or in contact with flammable
materials (such as gauze or surgical drapes). Electrosurgical accessories that
are activated or hot from use can cause a fire. Use a holster to hold
electrosurgical accessories safely away from personnel and flammable materials.

Fire Hazard Do not use extension cords.

Fire Hazard For continued protection against fire hazard, replace fuses only with

fuses of the same type and rating as the original fuse.

Electric Shock Hazards

Warning

Connect the generator power cord to a properly grounded receptacle. Do not use
power plug adapters.

Do not connect a wet power cord to the generator or to the wall receptacle.

Disconnect the power cord before servicing the generator. To allow stored energy
to dissipate after power is disconnected, wait at least five minutes before
replacing parts.

Always turn off and unplug the generator before cleaning.

Do not touch any exposed wiring or conductive surfaces while the generator is
disassembled and energized. Never wear a grounding strap when working on an
energized generator.

LigaSure Vessel Sealing Generator Service Manual 1-3

Warnings, Cautions, and Notices

Warning

When taking measurements or troubleshooting the generator, take appropriate
precautions, such as using isolated tools and equipment, using the “one hand
rule,’ etc.

Potentially lethal AC and DC voltages are present in the AC line circuitry, high
voltage DC circuitry, and associated mounting and heat sink hardware described
in this manual. They are not isolated from the AC line. Take appropriate
precautions when testing and troubleshooting this area of the generator.

High frequency, high voltage signals that can cause severe burns are present in
the RF output stage described in this manual. Take appropriate precautions when
testing and troubleshooting this area of the generator.

Servicing

Caution

Read all warnings, cautions, and instructions provided with the Valleylab
LigaSure electrosurgical generator before servicing.

The generator contains electrostatic-sensitive components. When repairing the
generator, work at a static-control workstation. Wear a grounding strap when
handling electrostatic-sensitive components, except when working on an
energized generator. Handle circuit boards by their nonconductive edges. Use an
antistatic container for transport of electrostatic-sensitive components and circuit
boards.

1-4 LigaSure Vessel Sealing Generator Service Manual

Warnings, Cautions, and Notices

Calibration

Caution

To avoid inadvertent coupling and/or shunting of RF currents around the resistor
elements, keep the resistors at least four inches (10.2 cm) away from any metal
surface including tabletops and other resistors. This is especially true if several
resistors are connected in series or parallel to obtain a specified value. Do not
allow the resistor bodies to touch each other.

Notice

After calibration, the generator will be ready to use only after you initiate the
internal self-test by turning the generator off, then on.

Calibrate the generator after you install a new battery. Calibration values are lost
when the battery is replaced.

Calibrate the generator after you install a new control board.

Calibrate the generator after you service, repair, or install new components, or
after you replace any generator board assembly.

Cleaning

Notice

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

LigaSure Vessel Sealing Generator Service Manual 2-1

General Description

General Description

The LigaSure vessel sealing system is an isolated output electrosurgical generator
that provides power for vessel sealing and bipolar surgery.

It includes the following features:

• LigaSure vessel sealing technology

• Vessel sealing regrasp indicator alerts you to situations where a full seal cycle

has not been achieved

• Bipolar and macrobipolar modes

• Instant Response technology

• Memory button to recall the most recently used intensity and power settings

• Smart interface for connecting a Valleylab LigaSure handset or smart

connector adapter

• Adjustable volume for the activation tone

• Handswitch or footswitch activation

• RF activation port, RS-232 serial port, and expansion port

Vessel Sealing

The LigaSure vessel sealing system provides precise energy delivery and
electrode pressure to vessels for a controlled time period to achieve a complete
and permanent fusion of the vessel lumen. This system works on isolated arteries
and veins up to and including 7 mm in diameter and tissue bundles. The system
has been optimized to produce minimal sticking, charring, or thermal spread to
adjacent tissue.

2-2 LigaSure Vessel Sealing Generator Service Manual

Bipolar Operation

Two modes are available:

• Bipolar – for most applications. The system provides low voltage to prevent
sparking. The power remains constant over a specific range of tissue
impedance, allowing a consistent tissue effect.

• Macrobipolar – for bipolar cutting or rapid coagulation. The system provides
higher voltage and greater power than with the bipolar mode.

Instant Response Technology

The LigaSure generator automatically senses tissue impedance and adjusts the
output to maintain a consistent effect across different tissue types. This
adjustment is based on the power setting and the level of tissue impedance. The
system controls maximum output voltage to reduce tissue damage and to
minimize sparking.
