Service Personnel Safety
Valleylab stresses safety in the use and servicing of its electrosurgical equipment. This chapter presents the following:
•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 |

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.
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.
Safety Personnel Service
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.

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
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.
