During surgery, the following are suggestions that a surgeon may wish to follow:
•
The surgeon should use the impedance audible and visual feedback system as a guide to
optimize the desired level of tissue desiccation. The relative degree of desiccation is
determined by the decrease in alarm pitch and decrease in the number of stars on the
display graph. These indicators show tissue desiccation progress– this is dependent on the
thickness and type of tissue. The surgeon can choose to continue to apply power but this
may increase the potential for tissue sticking.
•
The impedance feedback system may indicate a decrease in impedance during activation,
with an increasing tone and an increase in the number of stars on the display. This may be
due to conductive fluids being released from the tissue or flowing from adjacent areas.
Changing the grasp during activation will also change the indication sequence. It is
advisable to maintain constant grasp force and wherever possible to lift the tissue away
from fluid pools during activation.
•
When using the Gyrus ACMI PK instruments that require tissue grasping, to optimize
performance in the VP mode, tissue should be grasped firmly with the instrument to
maintain constant pressure during activation. If, on application, shorting occurs then the
tissue should be regrasped, varying tissue position and/or force as necessary. The
surgeon should take care when grasping very thin tissue but if shorting continues the
surgeon can leave the jaws slightly open and twist as the power is applied. If tissue
adherence to the instrument jaws occurs, regrasp and reapply.
•
When using PK forceps type instruments, coagulating effect will occur to the tissue between
coagulating surfaces. Continue to activate the PK forceps until it has been determined that
the desired tissue effect is achieved. Both coagulating surfaces should be in equal contact
with tissue for optimum coagulation. If both jaws come in contact with one another (metal
to metal) or have minimal tissue involvement, the desired tissue effect may be substantially
reduced.
•
When using the Gyrus ACMI PK LP Scissors the optimum coagulation performance is
attained when rotating the tips clockwise through 90 degrees as power is applied.
•
When using the PK modes with the Gyrus ACMI PK L-Hook, irrigation with saline will
enhance the cutting action. If the instrument is failing to achieve adequate cutting, the
surgeon can apply power and move the instrument from side to side to maintain the cutting
action. Cutting may also be improved by taking smaller bites of tissue and by applying
counter traction to the tissue to be cut.
•
When using the PK modes with the Gyrus ACMI PK L-Hook, try to avoid excessive build up
of coagulum between the hooks. This will diminish coagulation performance and increase
smoke production during cutting.
•
When using the PK modes with the Gyrus ACMI PK Needle to produce a hemostatic
incision, it is advisable to change the default mode to ThermoKinetic mode: the hemostatic
effect increasing from T2 to T1.
•
When using any of the instruments in the Gyrus ACMI PK range in the VPC mode the
default setting should be used. If the power is increased, there will be a potential increase
in the thermal spread.
