Foreword

General Electrosurgical Hazards

WARNING

 Any electrosurgical procedure is safest if moderate control settings are used along with minimum

activation times. Prolonged activations without the electrode in contact with the tiss ue should be avoided.

 Confirm proper electrosurgical power setting before proceeding with surgery. Use the lowest power

setting that achieves the desired surgical effect.

 In order to lessen the possibility of creating unintended burns, activate the electrosurgical generator

only when the active electrode is near or touching the target tissue.

 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 on the product package for proper return electrode placement and use.

 In some circumstances, 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 a 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 earth referenced and isolated output generators.

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

 Avoid skin to skin contact points, such as fingers touching leg, when positioning the patient.  Place two to three inches of dry gauze 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.

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

 Keep electrical connections dry while in use to prevent potential conduction of High Frequency (HF)

current to the user.

 Potentially hazardous conditions may exist when accessories of similar connector types are

intermixed. Be certain that accessories are appropriate for the type of electrosurgical generator output used and the intended application.

 While using electrosurgery, the 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).

Foreword

Active Accessories and AEM Monitor

WARNING

 These devices have been specifically designed for use in electrosurgery. Do not use for other

procedures.

 Do not wrap accessory cords around metal objects. Wrapping cords around metal objects may induce

currents that could lead to shocks, fires, or injury.

 The electrode tip may remain hot enough to cause burns after the electrosurgical current is

deactivated.

 When not in use, place accessories in a clean, dry, nonconductive and highly visible area not touching

the patient. Inadvertent contact with the patient may result in burns.

 Inadvertent activation or movement of the activated electrode tip outside the field of vision may result

in injury to the patient. Use these instruments only under conditions that ensure adequate visualization.

 Localized burns to the patient or physician may come from electrical currents carried through

conductive objects (such as cannulas or scopes). Electrical current may be generated in conductive objects by direct contact with the active accessory cable being in close proximity to the conductive object.

 Ensure that the insulation of conventional, nonshielded disposable and reusable laparoscopic

instrumentation is intact. Compromised insulation of nonshielded instruments may lead to shocks or burns to the patient or surgical personnel.

 When using laparoscopic instrumentation with metal cannulas, the potential exists for abdominal wall

burns to occur in the event of direct electrode tip contact to the cannula.

 Refer to the cannula manufacturer’s instructions before inserting the electrode into the cannula. To

avoid damaging the electrode or injuring the patient, insert and withdraw them carefully.

 Inspect cords for breaks, cracks, nicks or other damage before every use. Verify that end of life

indicators are not present. If any of these are present, do not use. Failure to observe this precaution may result in injury or electrical shock to the patient or operating personnel.

 Damaged external insulation on instruments AND incorrect setup of the AEM Monitor may result in a

risk of unintended patient burn. Do not use product having damaged insulation.

 When an alert is presented by the AEM Monitor, discontinue use of the electrosurgical current

immediately. Find the cause of the alert and correct it before continuing use.

 Damaged internal insulation of the instrument, or loss of shield continuity, may cause AEM Monitor

alarms. For maximum patient safety, discontinue use of the instrument if this occurs.

 A single AEM instrument must be the sole conductor of energy to tissue. Do not conduct energy by

touching an AEM instrument to a second instrument contacting tissue. The second device will not be protected from capacitive coupling and insulation failure.

 Good operating room practice suggests that connections of accessories to electrosurgical generators

be made only while the generator is off or in standby mode.

 Use the AEM Monitor only if the Power On Self Test (POST) has been properly completed (see

Section 3 for details). Otherwise, AEM functions may not be operative.

CAUTION

Read the instructions, warnings, and cautions provided with the AEM Monitoring System accessories before using. Their specific instructions are not included in this manual.

AEM Monitoring will not function without the us e of a dual pad return el ec trode and an electrosurgical generator equipped with contact quality monitoring patient safety technology.

Limit power setting to 80 watts or lower as specified in the power settings tables (see Section 3). Higher settings may result in spurious insulation failure alarms and/or insulation breakdown. Refer to instrument instructions for use for other limits.

Introduction

Active Electrode Monitoring

Active electrode monitoring technology can eliminate the risk of stray electrical energy caused by insulation failure and capacitive coupling and thus helps to prevent unintended internal burn injury to the patient. AEM instruments direct electrosurgical energy where the surgeon desires, while continuously monitoring the current flow to prevent stray electrosurgical energy from insulation failure or capacitive coupling.

AEM instruments have a patented, multi-layered design with a built-in shield, much like the third wire ground in standard electrical cords. The shield in these instruments is referenced back to a monitor at the electrosurgical generator. In the event of a harmful level of stray electrical energy, the monitor shuts down the power; ensuring patient safety. The AEM system protects against capacitive coupling by providing a neutral return path for capacitively coupled electrical current. Capacitively coupled energy is continually drained away from the instrument and away from the patient through the protective shield built into all AEM instruments.

Monopolar Electrosurgery

In monopolar electrosurgery, the surgical instrument contains only the active electrode. A separate return electrode attached to the patient recovers the current that passes through the patient and returns it safely to the electrosurgical generator.

Monopolar electrosurgery is used for most surgical procedures that require sparking to tissue, such as those in which tissue must be cut or coagulated over wide areas.

Bipolar Electrosurgery

In bipolar electrosurgery, the surgical instrument includes both electrodes. A patient return electrode is not used. Current flows between the two electrodes and through the tissue contacted by the instrument, heating that tissue.

In bipolar electrosurgery, control is needed to ensure the correct degree of heating.

5 Principles of Operation

Electrode Insulation

Zone 1

Zone 2

Zone 3

The AEM Monitor is divided into two separate functional parts: the AEM Monitor portion (Monopolar) and the End Point Monitor portion (Bipolar).

Theory of Operation – AEM Monitoring S ystem (Monopolar)

The AEM Monitoring System enhances safety by detecting insulation breakdowns and blocking stray currents that may not be detected by the surgeon during electrosurgical procedures. Indicators identify “Set up” and “Operative” alarms so that the proper corrective action can be taken.

During minimally invasive procedures, monopolar electrosurgery has safety and performance issues that differ from those of open procedures.

The safety of the patient depends, in part, on the quality of electrical insulation on the extended electrodes, and the amount of current which is conducted through the insulation due to capacitance. These potential electrical problems are compounded by the fact that only a small portion of the total length of the insulation may be viewed by the surgical team.

Zones 2 & 3 are likely out of the surgeon’s field of view. Electrosurgical equipment produces high voltage radio-frequency energy. These high

voltages require insulation on the electrodes to eliminate the flow of current except at the tip. Normal wear and tear of the instruments may degrade the insulation, and such defects may be outside of the normal field of view. Consequently, a failure capable of causing harm may go unnoticed.

Failure

Capacitively coupled currents also have the potential for causing burns. The radio-frequency energy used in electrosurgery will flow between closely spaced conductors even though there is no direct connection between them. The active electrode and a metallic cannula are closely spaced conductors, and they form a capacitor which can conduct radio-frequency current. Testing has shown that 5% to 40% of the power indicated on the electrosurgical generator may be delivered from a metallic insulated trocar sheath to the patient’s tissues. This amount of power is enough to quickly cause a serious burn.

AEM Monitor

Electrosurgical

AEM Instrument

Return

Monopolar

The AEM instruments incorporate a layered design. AEM instruments are shielded and monitored to prevent stray electrosurgical burns along the shaft of the instrument caused by insulation failure or capacitive coupling. The protective shield built into all AEM instruments provides a neutral return path for capacitively coupled energy and protection from insulation failure. The shield is continuously monitored during surgery which provides continuous assurance of the integrity of the instrument.

Generator

2) Protection against Capacitive

Coupling

The AEM Monitor measures the currents flowing in the AEM instruments, detects faults in the insulation, and monitors the connections of the shield and the return electrode. The Monopolar Adapter connects the AEM Monitor to an electrosurgical generator. An AEM instrument and the return electrode connect to the AEM Monitor. When an insulation fault or connection fault is detected, the AEM Monitor interrupts the circuit to the electrosurgical generator. In the event of a fault, an alarm sounds and a visual indicator illuminates.

NOTICE

The peak open circuit voltage produced by the electrosurgical generator may be slightly reduced when it is used with the AEM system. Normally the voltages produced under loaded conditions are not significantly altered.

Theory of Operation – End Point Monitoring System (Bipolar)

The surgeon may use the Bipolar Current Indicator (a radio-frequency (RF) ammeter) to aid in determining the end point of bipolar electrosurgical desiccation.

Desiccation is a process whereby heat is dissipated in tissue, and the electrolytic fluid is driven away. As desiccation takes place the electrical impedance of the tissue and the flow of current changes. A bar graph displays the current from 0.1A to 1.1A. As the current increases, the frequency of clicks increases.

Use the Bipolar Current Indicator in conjunction with visual, tactile, temporal, and aural information observed during surgery. The surgeon must use all the information presented and interpret it with reference to experience to determine that desiccation is satisfactorily completed. Thus, it is important not to draw conclusions about the completion of desiccation from the indications of the Bipolar Current Indicator alone.

6 Surgical Use

Before Surgery

For setup and system checks of the AEM Monitoring System, see Section 3 System Setup.

WARNING

Fire Hazard. Do not use extension cords. Electric Shock Hazard. Connect the power cord to a properly grounded receptacle. Do not use power

plug adapters. Electric Shock Hazard. Do not attempt to connect or disconnect any cable during power activation. Electric Shock Hazard. Do not connect wet accessories to the generator. Ensure that accessories and

adapters are correctly connected and that no metal is exposed. Do not use the AEM Monitor unless the system properly completes the automatic self-check. Otherwise,

AEM functions may not be operative. Good operating room practice suggests that connections of accessories to electrosurgical generators be

made only while the generator is off or in standby mode. Confirm proper power settings before proceeding with surgery. Use the lowest power setting possible for

the minimum time necessary to achieve the desired surgical effect.

CAUTION

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

NOTICE

Monopolar Surgery

Active electrode monitoring is intended to control stray monopolar energy caused by insulation failure and capacitive coupling on the shaft of the AEM instrument.

WARNING

Only an AEM instrument provides active electrode monitoring. Other conductive objects at or near the surgical site are not protected. Do not touch those objects with the active instrument.

CAUTION

The AEM system technology is designed to safely deliver electrosurgical energy and to prevent injury caused by insulation failure and capacitive coupling. The AEM Monitor is not intended to test for insulation damage on laparoscopic instruments. Do not attempt to use this system as an instrument inspection tool.

AEM Monitoring will not function without the use of a dual foil return electrode and an electrosurgical generator equipped with contact quality monitoring patient safety technology.

Read and review all instructions pr ovid ed by the manufacturer of the dual foil return electrode you will be using.

Read and review all instructions provided by the manufacturer of the AEM accessories you will be using.

Surgical Use

Bipolar Surgery

End Point Monitoring of the bipolar instrument will assist the surgeon in confirming the end point of bipolar desiccation. This information is displayed on the left front panel of your AEM Monitor as an illuminated visual graph and a volume controlled audible indicator.

WARNING

Electric Shock Hazard. Do not activate the gen erator b ipo lar outp ut wh en the Bipo lar Adap ter is connected to the generator, but not connected to the AEM Monitor. Accessible pins of the adapter may lead to shock or burns to surgical personnel.

CAUTION

General Precautions

Return Electrode

CAUTION

AEM Monitoring will not function without the use of a dual foil return electrode and an electrosurgical generator equipped with contact quality monitoring patient safety technology.

Active Accessories

WARNING

These devices have been specifically designed for the use in electrosurgery. Do not use for other procedures.

Do not wrap accessory cords around metal objects. Wrapping cords around metal objects may induce currents that could lead to shocks, fires or injury.

The electrode tip may remain hot enough to cause burns after the electrosurgical current is deactivated. When not in use, place accessories in a clean, dry, nonconductive and highly visible area not touching the

patient. Inadvertent contact with the patient may result in burns. Inadvertent activation or movement of the activated electrode tip outside the field of vision may result in

injury to the patient. Use these instruments only under conditions that assure adequate visualization. If electrodes are touching other instruments, do not activate them because unintended tissue damage may

occur. Contact of the active electrode with any metal (such as hemostats and clamps) will greatly increase current

flow and can result in unintended burn injury. When using laparoscopic instrumentation with metal cannulas, the potential exists for abdominal wall

burns to occur in the event of direct electrode tip contact to the cannula. Refer to the cannula manufacturer’s instructions before inserting the electrode into the cannula. To avoid

damaging the electrode or injuring the patient, insert and withdraw them carefully. Inspect cords for breaks, cracks, nicks or other damage before every use. Verify that end of life indicators

are not present. If any of these are present, do not use. Failure to observe this precaution may result in injury or electrical shock to the patient or operating personnel.

Damaged external insulation on instruments AND incorrect setup of the AEM Monitor may result in a risk of unintended patient burn. Do not use product having damaged insulation.

A single AEM instrument must be the sole conductor of energy to tissue. Do not conduct energy by touching an AEM instrument to a second instrument contacting tissue. The second device will not be protected from capacitive coupling and insulation failure.

CAUTION

Read the instructions, warnings, and cautions provided with the AEM Monitoring System accessories before using. Their specific instructions are not included in this manual.

6-2 EM3 AEM Monitor User’s Guide

Damaged internal insulation of the instrument, or loss of shield continuity, may cause interruption of energy delivery from the ESU. For maximum patient safety, discontinue use of the instrument if this occurs.

Operating Room Trouble shoot ing

When using AEM Monitoring, successful electrosurgery depends on an absence of critical fault conditions. Should one occur, the AEM Monitoring System interrupts the power delivery from the electrosurgical generator (ESU) to the AEM instrument until the fault condition is corrected.
