Johnson & Johnson ETHICON Megadyne User manual

*Bipolar and monopolar accessories may not be activated simultaneously. Only one monopolar accessory can be activated at a time.
Auto bipolar button
Activates AUTO bipolar mode,
removing the need for a
footswitch. Press to select
a 1-second delay (LONG),
0.5-second delay (SHORT)
or no delay (ON) prior to the
onset of energy delivery.
Recall button
Push after startup to recall last
mode and power setting used.
During use, toggle between
modes to maintain the last
power setting used.
Patient return electrode
alarm
Lights green when patient return
electrode is connected and CQM
circuit is complete. Lights red,
accompanied by an audible alarm,
when circuit is broken or electrode
is disconnected.
Monopolar receptacles
Accept two handswitching accessories or
one footswitching and one handswitching
accessory. Press "CUT" or "COAG" button
on pencil or foot pedal to activate attached
instrument.*
Patient return electrode
receptacle
Accepts both single plate and
split plate return electrodes.
Ethicon recommends the use of
a MEGADYNE™ MEGA SOFT™
Reusable Patient Return Electrode.
On/O power switch
Press to turn on generator.
Switch will illuminate
green. Once startup and
self-diagnostic check are
complete, dashed lines appear
in power setting windows.
Bipolar receptacle
Accepts a footswitching (2-pin)
or handswitching (3-pin) accessory.
Press footswitch or close tips of bipolar
forceps (when using auto bipolar) to
activate attached instrument.*
Bipolar current meter
tone button
Press to activate or deactivate
bipolar current meter tone.
During use, starts o as a rapid
tone then reduces to a slower,
metered tone as current low
is diminished.
Power up/down buttons
In all coagulation modes and in PURE and BLEND cut modes,
arrows adjust power in 1-watt increments up to 40 watts and in
increments of 5 watts thereafter. In the GEM cut mode, arrows
switch mode from GEM High (H) to GEM Low (L). In bipolar modes,
arrows adjust power in 1-watt increments up to 80 watts.
Bipolar current meter
Provides a visual indication of current low.
As tissue becomes desiccated and dries,
current low is diminished, as illustrated by
light bars on current monitor.
MEGADYNE™ Electrosurgical Generator
Quick Start Guide

MEGADYNE™ Electrosurgical Generator
Quick Start Guide
The MEGADYNE™ Electrosurgical Generator provides multiple cut, coagulation, bipolar modes and power settings. The ETHICON MEGADYNE™
Electrosurgical generator is designed to optimize energy delivery to minimize tissue damage through proprietary software and algorithms14*
Cutting
PURE CUT MODE
Provides a standard cutting eect.5
BLEND MODE
Provides a cutting eect and a higher level of hemostasis than either the “GEM” or “PURE” cut modes. 5
GEM (Geometric Electron Modulation)
The Geometric Electron Modulation (GEM) mode of the ETHICON MEGADYNE™ Electrosurgical Generator
automatically controls the output power of the generator to provide a consistent cutting eect.5
Coagulation
COAG 1 MODE
Is designed to allow the active electrode to eiciently move through tissue for coagulation with dissection.5
COAG 2 MODE
Delivers a more gradual onset of energy that results in a mild delivery of coagulation with dissection.5
FULGURATION MODE
Is designed to provide hemostasis in a broader area with less depth of tissue damage when compared
to desiccation.5
SOFT COAG MODE
Is designed to provide coagulation and desiccation at a slow rate with deep thermal penetration.5
Bipolar
MICRO BIPOLAR MODE
Is designed to deliver consistent power to provide a tissue eect for all standard bipolar applications.5
MACRO BIPOLAR MODE
Delivers a rapid onset of power and higher voltage power output compared to Micro Bipolar.5
AUTO
Is designed to remove the need for a bipolar footswitch.5
Power settings
Settings will vary according to surgeons’ preferences. To increase power
intensity, increase the power setting. To decrease the intensity of power,
lower the power setting. If a proper setting is not known, set the generator
at a low setting and increase power until the desired eect is obtained.
Error codes
To clear an error, turn the MEGADYNE™ Electrosurgical Generator o,
then on, to restart the machine and clear the error. If the error does not
clear, record the error code displayed and contact your Ethicon Sales
Representative.
Cleaning the MEGADYNE™ Electrosurgical Generator
Disconnect the power cord from the wall outlet prior to cleaning the
generator. Use a mild detergent or disinfectant and a damp cloth to
clean the generator. Do not use abrasive, corrosive or caustic cleaning
or disinfectant agents that could scratch the front panel or damage the
generator. Do not allow luids to drain inside the generator.
