Description
OVERVIEW OF THE G400 WORKSTATION
Bipolar electrosurgery is a familiar tool widely employed in surgery. Based on similar
principles, the Gyrus ACMI PlasmaKinetic technology combined with Gyrus ACMI PK instruments provides effective coagulation and cutting of tissue.
Gyrus ACMI PlasmaCision technology combined with Gyrus ACMI PC instruments provides simultaneous cutting and coagulation of tissue.
A key feature of the Gyrus ACMI G400 Workstation is the capability of the G400 Workstation to identify the type of Gyrus instrument connected to it. The identification of the instrument causes the G400 Workstation to operate in either the PlasmaKinetic
PlasmaCision (PC) mode. This identification feature assigns default output designed to
produce the desired electrosurgical effect for that particular instrument. The user can change this default to obtain a wider range of PlasmaKinetic (PK) or PlasmaCision (PC) outputs from the device. Power and mode adjustments can be performed by the front panel buttons or via the footswitch with the selected output on the user display.
By adjusting power and voltage two tissue effect modes can be produced.
In the cut mode, PlasmaKinetic (PK) RF energy is used to vaporize/transect soft tissue. PK energy heats tissue cells quickly at a high temperature (in excess of 400F or 200C). The steam created causes the cell to explode. With many cells exploding, the surgeon achieves a cutting effect. With the PlasmaKinetic mode, an electrically charged field is created around one pole of the PK instrument resulting in vaporization of tissue. This active pole provides effective tissue cutting with a predetermined level of hemostasis.
In the coagulation mode, PlasmaKinetic (PK) RF energy provides rapid, predictable and
controlled elevations in tissue temperature to tissue located between the electrodes of a Gyrus ACMI instrument. This mode can be used to coagulate tissue, seal vessels and provide hemostasis. Coagulation allows protein to reorganize and form a coagulum without rapid desiccation.
Instruments are designed to provide vaporization/transection and/or coagulation/sealing of tissue, using the yellow and blue pedals respectively of the footswitch.
The Gyrus ACMI G400 Workstation is intended to be used only with designated Gyrus ACMI instruments, cables, footswitch and accessories.
To avoid incompatibility and unsafe operation only Gyrus ACMI cables and accessories should be used.
The G400 Workstation uses instrument specific limits on the system output voltage and power. Gyrus ACMI accessories are rated for at least the maximum peak output voltage of the system.
