SECTION 6 DURING SURGERY
Gyrus ACMI PlasmaKinetic SuperPulse Generator
USER MANUAL
Part Number: 144012-MB
Page 6-1
This section describes how to use the SuperPulse Generator during surgery.
6A. Recommendations
During
Surgery
•
Refer to the Cautions and Warnings at the front of this manual.
•
Unless circumstances dictate otherwise, use Gyrus ACMI PK instrument default
settings to enhance patient and user safety.
•
Remove any gross tissue build-up from the tips of the instruments to maximize
surgical effect.
•
Activate only for sufficient time to achieve the desired surgical effect; and use the
Impedance and Cut bar graph Indicator systems to aid, but not replace, surgeon
judgment.
•
Ensure that the correct footswitch is used for the desired output mode.
•
Tissues dry out during surgery and regular irrigation of tissues with saline will ensure
repeatable surgical effects.
It should be noted that the SuperPulse Generator incorporates a PK mode output
power boost feature on some instruments. When connected to a PK Plasma-V
Resectoscope Instrument, this boost is designed to allow rapid formation of the
plasma corona around the tip of the instrument. It functions by automatically
increasing the selected power output setting of the SuperPulse Generator by 25%
during the first 400 milliseconds of cut activation, up to a maximum output of 200W.
Similarly when connected to a PlasmaSEAL instrument, the boost functions
automatically by increasing the power output to 200W for the first 200 milliseconds of
cut activation, thereafter returning to the selected power output setting.
6B. PK Default Settings
The power settings and output mode used for the intended procedures vary considerably
both with the surgeon’s technique and the configuration of the instrument being used.
Some experience may be required before optimal power settings to suit the particular
surgical technique are determined. Until the surgeon becomes familiar with the
characteristics of the system, caution should be used when adjusting PK default settings,
which have been allocated to provide safe and effective performance.
The Generator incorporates a Vapor Pulse Coagulation (VPC) mode, which is the default
applied to many of the Gyrus ACMI PK instruments. This mode is designed to reduce both
thermal margins and tissue sticking, providing controlled and repeatable outcomes under a
variety of surgical situations. The energy absorption is measured during each pulse to
provide the Impedance Indicator feedback as a guide to when tissue treatment is
completed.
6C. Activation: Output Selection and Audible Tones
In common with conventional electrosurgical generators, output activation is achieved using
the blue and yellow pedals of the footswitch.
BLUE PEDAL: Vapor Pulse Coagulation (VP1, VP2, VP3) and Desiccate. (DES). Activation
accompanied by flashing of the desiccate power display and an audible tone. In VP1, VP2
VP3 modes used in conjunction with Gyrus ACMI PK instruments, the audible tone acts as
the Impedance Indicator feedback. On instruments capable of VP activation modes, the
DES mode also has the same audible Impedance Indicator feature.
