Vessel Sealing
The LigaSure vessel sealing generator is an isolated output generator that provides power for vessel sealing and bipolar surgery. It includes the following features: •
LigaSure vessel sealing technology
•
Vessel sealing Regrasp indicator that alerts you to situations where a full seal cycle has not been achieved
•
Bipolar and macrobipolar modes
•
Instant Response technology
•
Memory button to recall prior intensity and power settings used
•
Smart interface for connecting a Valleylab LigaSure instrument or smart connector adapter
•
Adjustable activation tone volume
•
Handswitch or footswitch activation
•
RF activation port, RS-232 serial port, and expansion port
Vessel Sealing The LigaSure vessel sealing system can be used on vessels and tissue bundles up to and including 7 mm in diameter. This system provides precise energy delivery and electrode pressure to vessels for a controlled time period to achieve a complete and permanent tissue fusion. The system has been optimized to produce minimal sticking, charring, or thermal spread to adjacent tissue.
Bipolar Modes Two modes are available: bipolar and macrobipolar.
1-2
•
Bipolar may be used for most applications. The voltage is kept low to prevent sparking. The power remains constant over a specific range of tissue resistance, allowing a consistent tissue effect.
•
Macrobipolar may be used for bipolar cutting or rapid coagulation. Voltage is higher and there is more power than with the bipolar mode.

Instant Response Technology
Instant Response Technology
Accessories The accessories that complete the LigaSure vessel sealing system include multiple reusable and single use instruments for open and laparoscopic procedures. Each reusable instrument requires a corresponding single use electrode.
LigaSure User’s Guide

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

This receptacle is designed to accept a blue bipolar Valleylab smart connector adapter. You must use this smart connector adapter to connect any bipolar instrument. You can connect either a footswitching (two-pin connector) or handswitching (three-pin connector) bipolar/macrobipolar instrument to the smart connector. When the blue bipolar Valleylab smart connector adapter is correctly connected, the bipolar receptacle light changes from red to green. The light must be green for the system to operate.

Vessel Sealing Footswitch Receptacle (purple) Connect either the single pedal vessel sealing footswitch or the two pedal vessel sealing footswitch to the purple receptacle. Two Pedal Footswitch For the LigaSure instrument connected to the vessel sealing instrument receptacle on the front panel, the connected two pedal footswitch activates either the vessel sealing output function (round purple pedal) or the bipolar output function (blue square pedal). Single Pedal Footswitch
Bipolar Footswitch Receptacle (blue) Connect the bipolar/macrobipolar footswitch when you connect a bipolar footswitching instrument to the generator. Connect the two pedal bipolar footswitch to this receptacle. The connected footswitch activates bipolar (blue pedal) or macrobipolar (gray pedal) output for the bipolar instrument that is connected to the bipolar instrument receptacle on the front panel.

Controls and Receptacles
For the LigaSure instrument connected to the vessel sealing instrument receptacle on the front panel, the connected single pedal footswitch activates only the vessel sealing output function.
Rear Panel
Option Panel A removable plate on the rear panel covers a serial port, an RF activation port, and an expansion port. To review the technical specifications for each port, refer to Chapter 9. Serial Port Allows connection of a computer to the generator to obtain information using RS-232 communications protocol
RF Activation Port Allows a connected device to receive information during RF activation of the generator, which can then generate a response in the device
