FOOTSWITCH 112101 USED IN SINGLE LINEAR MODE (SING. LIN.)
As can be seen in the figure, the pedal unit consists of a main pedal that can be
moved vertically and/or horizontally and three separate controls that activate
CONTINUOUS IRRIGATION, switching between "MMP 1-2" and "MMP 1-2-3" (depending
on the function activated), and the Function Change.
When the main pedal
is slightly depressed,
the "IRRIGATION" valve
opens, permitting
fluid to enter the
infusion set.
When the main pedal
is depressed beyond
detent #1, the
selected pump is
activated, causing
aspiration and
irrigation to occur
simultaneously. If
linear control mode
for VACUUM (and/or
flow, if in peristaltic
mode) is selected on
the console, further
depression of the
pedal will increase
aspiration level
linearly.
When the surgeon presses the main pedal beyond the first detent, this also
activates the vitrectomy scalpel. If linear control mode for CUT RATE (PHACO TIP
STROKE) is selected on the console, further depression of the pedal will increase
the cutting rate (phaco tip stroke). To disable vitrectomy, rotate the main pedal to
the right; ASPIRATION and IRRIGATION still remain active. If continuous irrigation is
active, aspiration (and, eventually, cutting) will begin immediately after a slight
depression of the pedal; this will extend the available travel for linear control.
In the U/S mode when the main pedal is pressed beyond the second detent, the
phacoemulsifier handpiece is activated. Further depression of the pedal will
increase the phacoemulsifier handpiece travel (U/S power) (if the linear control
mode is active) or the Burst Emission frequency. If continuous irrigation has been
