Instant Response Technology

The Covidien Force EZ Electrosurgical Generator 8CS (also called the Force EZ-8CS generator in this guide) with Instant Response technology is an isolated output electrosurgical generator that provides power for cutting, desiccating, and fulgurating tissue during bipolar and monopolar surgery. It includes the following features: •

Instant Response technology

•

Standard bipolar mode

•

Two monopolar cut modes: pure and blend

•

Two monopolar coag modes: desiccate and fulgurate

•

The Covidien REM Contact Quality Monitoring System

•

•

Argon Gas Delivery Unit II system compatibility

•

Tilt support provided by the bottom mounted handle or use with Covidien carts

Covidien electrosurgical generators, patient return electrodes, and active accessories are designed to work as a system. Covidien offers a selection of patient return electrodes and electrosurgical instruments that are fully compatible with this generator. When considering other manufacturer’s patient return electrodes and/or active accessories, customers should seek detailed user instructions and warning information from the manufacturer.

Instant Response Technology The Force EZ-8CS generator automatically senses resistance and adjusts the output voltage, current and power to maintain a consistent effect across different tissue density. This adjustment is based on the selected mode, power setting, and level of tissue resistance. The maximum output voltage is controlled to reduce capacitive coupling and video interference and to minimize sparking. This technology applies to the standard bipolar mode, the cut modes, and the desiccate 2 and desiccate 3 coag settings. It does not apply to the desiccate 1, fulgurate 1, and fulgurate 2 coag settings.

Bipolar Modes

The Force EZ-8CS generator provides a standard bipolar mode usable for most bipolar applications. Delicate tissue requires less heat to desiccate quickly. The generator provides low voltage, continuous current for faster desiccation without sparking.

Introduction

Bipolar Modes

The possibility of sparking increases as desiccated tissue dries and becomes more resistant. The generator protects against sparking by limiting the bipolar voltage at relatively high levels of tissue resistance. For details about the bipolar output characteristics, refer to Chapter 9, Technical Specifications.

Monopolar Cut and Coag Modes Cut Modes Two cut modes-pure and blend-allow a wide range of power settings necessary to perform diverse surgical procedures. •

Pure provides an even cut with little or no hemostasis. It offers good cutting performance over a wide range of tissue resistance.

•

Blend provides cutting ability with additional hemostasis.

Coag Modes Two coagulation modes help control the size of the area and the depth of penetration during tissue coagulation. The desiccate mode has three settings; the fulgurate mode, two settings. You can select, as default settings, one desiccate setting and one fulgurate setting. For a description of each setting, refer to Special Features on page 1-5. •

DESICCATE dehydrates and destroys tissue without sparking or cutting. Because the active electrode directly touches the tissue, more current reaches the patient. Desiccation places the greatest demand on the patient return electrode.

•

FULGURATE coagulates tissue by sparking from the active electrode, through air, to the patient tissue. Since sparks may spray unpredictably from the electrode during fulguration, using fulguration for delicate tissue or in confined areas can complicate surgery. Accidental sparking to adjacent areas can occur as tissue at the surgical site dries and becomes more resistant to current flow.

For details about the output characteristics, refer to Chapter 9, Technical Specifications.

REM Contact Quality Monitoring System

REM Contact Quality Monitoring System During monopolar electrosurgery, a patient return electrode is always required to safely recover the current that flows through the patient’s body and return it to the generator. A reduction in surface area contact or poor conductivity between the patient and the return electrode can cause the current to become concentrated, potentially resulting in burns at the return electrode site. The Force EZ-8CS generator uses the REM Contact Quality Monitoring System to monitor the quality of electrical contact between the patient return electrode and the patient. The REM system is designed to minimize the risk of burns at the return electrode site due to a reduction in patient contact area during monopolar electrosurgery. Use of any return electrode other than a REM PolyhesiveTM patient return electrode may compromise the REM safety feature. This could result in a patient burn.

How the REM System Works The REM system continuously measures the resistance at the return electrode site and compares it to a standard range of safe resistance (between 5 and 135 ohms), thus eliminating intermittent false alarms that could result from small changes in resistance. The REM system also adapts to individual patients by measuring the initial contact resistance between the patient and the patient return electrode and lowering the baseline resistance if the contact resistance drops. A REM alarm sounds and the generator stops producing output power when either of the following occurs: •

The measured resistance is below 5 ohms or above 135 ohms, the limits of the standard range of safe resistance.

•

An increase in contact resistance is greater than 40% from the baseline measurement.

Electrodes Without the REM Safety Feature Warning Using a patient return electrode without the REM safety feature will not activate the REM Contact Quality Monitoring System.

When you use a patient return electrode that does not have the REM safety feature, the REM system cannot monitor the patient contact area as previously described. The REM system can monitor only the pin-to-pin resistance at the connector and can detect broken wires or connectors in the return electrode cord.

Special Features

Five special features allow customizing the Force EZ-8CS generator. You can access these features only in the setup mode. For details on selecting these features, refer to Setting Up the Special Features on page 4-14.

Introduction

Special Features

Desiccate Coag Settings The low (desiccate) coag mode provides three settings with subtle differences in output characteristics: •

Desiccate 1 is appropriate for the majority of surgical procedures. It provides tissue desiccation with a minimal tendency to cut or spark.

•

Desiccate 2 produces tissue desiccation and further reduces the chance of cutting or sparking by using the lowest possible voltage (200 Vrms).

•

Desiccate 3 uses a slightly higher voltage (300 Vrms) than the desiccate 2 setting, but offers comparable desiccation.

Fulgurate Coag Settings The fulgurate coag mode provides two settings: •

Fulgurate 1 produces coagulation of smaller areas without touching the electrode tip to the tissue.

•

Fulgurate 2 produces coagulation of larger areas without touching the electrode tip to the tissue.

Recall of Most Recently Used Modes and Power Settings When you activate this feature, the Force EZ-8CS generator will, when turned on, revert to the most recently used modes and power settings.

Default Coag Mode Important The default coag mode feature is available only when the most recently used modes and power settings feature is turned off.

You can select either desiccate or fulgurate as the default coag mode for the Force EZ-8CS generator. Each time you turn on the generator, it automatically selects the default coag mode.

Bipolar Instrument Receptacle

Bipolar Instrument Receptacle Caution Accessories must be connected to the proper receptacle type. In particular, bipolar accessories must be connected to the Bipolar Instrument receptacle only. Improper connection may result in inadvertent generator activation or a REM Contact Quality Monitor alarm.

You can connect either a footswitching or handswitching bipolar instrument to the Bipolar instrument receptacle.

Connect a footswitching instrument with a two-pin connector. or Connect a handswitching instrument with a three-pin connector.

Footswitch Receptacle, Button, and Indicators Connect a two-pedal Valleylab monopolar footswitch to this receptacle. Press the Footswitch Selector button to select bipolar or accessory output.

Use only a Valleylab monopolar footswitch with the Force EZ-8CS generator. Use of an incompatible footswitch may cause unexpected output. When the left arrow indicator illuminates green, the footswitch activates the instrument connected to the Bipolar Instrument receptacle.
