Double Pump RF functions and adjustments
Aspiration Switching
In double pump mode, the outflow from the joint is via the
Cannula. While a shaver or RF probe is activated, the outflow
from the joint is switched over to pass through the shaver hand
piece or RF probe respectively. A “
*
” symbol on the Display
indicates outflow path: shaver, cannula or RF Probe. The pump
can optionally delay the switching back to cannula for optimal
pressure control. The delay is set in Extended Setup. 5 seconds
delay should be selected if an Outflow Cannula is not used, but
the shaver or RF Probe is used as outflow fluid path.
Pressure Adjustment
The pressure setting can be adjusted with the Pressure increase/
decrease buttons (4).
Outflow Adjustment
If a Patient Cassette is used, The outflow setting can be adjusted
with the Flow/Suction increase/decrease buttons (7). The
buttons will adjust the outflow from the joint of the mode that
is currently active: If the Outflow Cannula is active, the outflow
for the Outflow Cannula will be adjusted.
Shaver Suction Setting
When a shaver is active, the suction can be increased/decreased
with the Flow/Suction buttons. When the shaver is connected
but not active, the outflow through the shaver hand piece
setting can be modified by pressing the Soft Key ‘Shaver’ on
the display. A shaver flow menu will appear on the display,
and the flow setting can be modified with the Flow increase/
decrease buttons (7). Soft Key ‘OK’ can be pressed to return
to the procedure screen.
RF Probe suction setting
When a RF generator is active, the suction can be increased/
decreased with the Flow/Suction increase/decrease buttons.
When a RF system is connected but not active, the suction
setting can be modified by pressing the Soft Key ‘RF Probe’ on
the display. A RF Probe suction menu will appear on the display,
and the suction setting can be changed in the range of 1 - 8
with the Flow increase/decrease buttons (7). Factory setting
is 8. These settings are based on experience and may be used
as a guideline and are not intended to replace the experience
and expertise of the user. Soft Key ‘OK’ can be pressed to return
to the procedure screen.
Cannula Function
When a Patient Cassette is used, pressing and holding the
Cannula pedal will increase flow through the joint without
increasing joint pressure. This feature is useful for eliminating
debris. The Display will indicate when Cannula function is
active. The pressure and outflow can be adjusted when Cannula
function is active.
Rinse Function
Pressing the Rinse pedal or lower right Soft Key will activate
the Rinse mode for 120 seconds. Rinse mode will increase the
pressure in the joint in Single mode, and also the outflow from
the joint in double mode. The pressure increase and outflow
is delayed after Rinse activation. The delays can be adjusted
in Extended Setup (factory setting is 0 delay for pressure and
2 seconds for outflow to avoid pressure drop).This feature is
useful for removing blood and controlling bleeding in the joint.
The Display will indicate when Rinse function is active. The
Rinse function can be turned off by pressing Rinse foot pedal a
second time or Soft Key “Rinse off”. When active, SmartVision
®
is inhibited. If a shaver or RF system is used during the Rinse
period, the Rinse function sets the pressure; but the shaver or
RF suction settings prevail. Rinse function outflow is set again
when the shaver or RF is deactivated. The Pressure and outflow
settings can be adjusted when Rinse function is active.
SmartVision
®
SmartVision
®
is a function to automatically increase pressure
in and flow through the joint if debris or blood is detected.
This feature can be turned On and Off with the SmartVision
®
button (8), and related LED is illuminated when SmartVision
®
monitoring is on. If blood is detected this is indicated in the
display. The pressure is increased by a set value (default value
is 50 mmHg), and outflow is increased by 50 ml/min.
When the liquid is clear of blood, the outflow and pressure
resumes the previously selected values. If the liquid is not clear
of blood within 8 seconds, the outflow is further increased by
50 % of the already increased outflow. The pressure increment
can be adjusted in Extended Setup. Factory default setting is
50 mmHg increase.
If debris is detected this is indicated in the display, and the
outflow is increased by a value (in percent). Factory default
setting is 50%.
Outflow Tracking
The LED adjacent to the Outflow Tracking button
(3) on the
keyboard indicates the status of Outflow Tracking. If the LED
is on, Outflow Tracking is active. The status of Outflow Tracking
can be changed by pressing the Outflow Tracking button. This
function regulates inflow to the surgery area to precisely replace
liquid removed by the outflow pump. The result is a constant
volume of fluid in the distended joint. Outflow Tracking is
available only when the Patient Cassette is used. A High Flow
Sheath for Arthroscopy is recommended for best performance.
Automatic reset to user default values
The Double Pump RF will reset the procedure settings for the
last procedure to user default values for the next patient when
the Patient Cassette is replaced. In Single mode, if the pump
has been stopped for more than 30 minutes, the user default
values are set.
