equipment had no effect on
this equipment. This
equipment without source and
electrostatic put power
supply, this system for
attachment within the
increase and change will not
lead to the increase of the
launching equipment and
immunity to reduce. The
equipment should not and
other equipment close or
layers use, if you must
close or layers use, should
be observed verification in
the use of the configuration
can be normal operation.
Three, installation
1, open the packing
container, check whether
conform to physical and
packing list.
2, first will stand for
good, will microscope lens
(the Lord, deputy
microscope) take out, it
will be on the left a shaft
insertion bending plate of
the bottom of hole, and the handwheel binding, again
will screw admiral shaft and
bending plate binding, and
the last in the after
electrify check each
function is normal use, such
as no problems can be pushed
into the operating room to
use.
Four, method of use
(1), in the surgery
microscope after the
installation, push them to
the right position surgery,
on the base of the two
brake, lock instrument, in
case microscope in surgery
about. If you want to
loosen, please tread down
locking lever next to the
pedal, the locking lever
will advance pop-up, thus
loosen instrument, this
instrument can move freely.
(2), switch on the power,
open frame on the power
switch.
(3), loosen the frame of all
a tight the handwheel (see
chart 1), mobile lens to
surgery surface (observation
surface) above (or front)
work focal length place (as
the lens focal length
decide) until the eyepiece
can see the observation
surface so far, lock on the
frame of the handwheel.
(4) and adjust the master
with the hand lens of the
eye from the size (figure 1,
8), to suit your distance.
(5), regulating drum become
times the handwheel (figure
1, 6), to the over-error of
2.5 (the largest
magnification).
(6), by foot pedal control
lens micro lifting device,
until see things surface.
(7), may be around eyes
vision not consistent, the
eyepiece of about objective
image definition is differ,
right now but screwing in or
spin out side of the
eyepiece.
Note: the left ocular
diopter position and
distance size on everyone
basic is fixed, adjusted the
is not allowed to
adjustment, such as surgery
surface does not clear
phenomenon, can adjust
working distance. (FIG. 5,
13)
(8), 6 x assistant mirror:
binocular assistant mirror
and primary mirror into 90
DHS position, according to
need to turn to the right or
left of the primary mirror,
as long as assistant mirror
turn to the left or right
position, and the main
mirror into 90 DHS postures,
adjust good visibility and
distance were observed.
(9), in the surgeon clear
observation, assistant
mirror observer can't see
clearly like, and the
surgeon is different, can
adjust the ocular diopter,
until clear so far. In the
process of operation
assistant mirror users
without the consent of the
the surgeon is can't
literally adjust the working
distance.
(11), the choose and buy a
(teach mirror, camera,
camera device) use.
(1), loosen 45 º eyepiece
group at the bottom of a
screw, take off the eyepiece
group.
(2), optical splitter
inserted his lens, location
is good, tighten the
monochrometer a screw.
(3), will eyepiece group
insert optical splitter,
location is good, tighten
the eyepiece group a screw.
(4), will teach mirror
insert monochrometer
interface (or so all can),
optical splitter another
side interface insert camera
or camera interface, would
connect the handwheel
tightening, and then put the
camera or CCD camera.
(5), and CCD camera with
signal wire and monitor and
video equipment connection,
can be realized in the
process of operation
SheLuXiang.
(12), after using it, you
should turn off light
switch, then turn off the
power switch.
(13), in lamp: loosen
bearing arm side department
of the four screws (figure
1, 12), upward force pull
out, can change the light
bulbs, in good again after
the original direction
insert, screw on screw can.
Five, maintenance and
matters need attention
(a) maintenance
1, use and storage
instrument place (generally
refers to the operating
room), should be kept clean,
pay attention to dust,
moistureproof, acid and
alkali resistant, etc have
corrosion volatile matter
qualitative erosion. Use
after application dust
shroud live.
2, special attention should
be paid to keep the optical
lens clean, fingers are not
allowed to touch the optical
lens surface. If the lens
surface dust, usable and
clean brush or brush wiped
the, also can use a
handkerchief to wipe gently.
If not careful hand met or
oil pollution, usable cotton
wool with a small amount of
ethyl ether ethanol mixture
(ethanol 30% ethyl ether
70%) is brushed try, wipe
try don't let the mixture
into the lens inside. In
order to avoid lens
degumming or mildew.
3, optical fiber is made of
many glass composition,
unfavorable had large
bending force, need bending,
curve radian but small (90 °
above), in order to avoid
broken, influence through
light, deposit should bend
coil.
(2) the matters needing
attention
1, this instrument is Ⅰ
class B equipment, request
supply network power supply
(220 v ± 22 v, 50 hz ± 1 hz)
has a good grounding line,
and when using please be
checked, lest cause security
risk. Instrument maximum
input power 220 va.
2, when replacing the fuse
please close instrument
power switch, unplug the
power plug, change the
specifications of the fuse
tube, in case produce
security risk.
3, in the operation such as
a bulb is damaged, it should
be timely enable spare lamp
lighting, change bulb must
be in stop 30 minutes after
tight, in order to avoid
high temperature scald.
4, instrument on the various
handwheel when use must be
binding, in order to avoid
accident. On the frame
regulating balance force
size the handwheel at the
balance arm after adjustment
is not active.
5, the instrument attached

for reference only
maintenance, are subject to
change without prior notice.
