tend to drift. After a period of time, drifting may be
experienced even though the knob is made tight.
This is usually due to the drawbar threads becoming
worn, requiring a replacement of the part.
Flex Arm Maintenance
Should the retractor arm seem less stiff than
desirable, even after full tightening of the knob, the
problem may be corrected as follows:
1. Turn the knob maximally counterclockwise,
making the arm fully loose (Figure 12).
Figure 12
2. While holding the chuck assembly with the ring
and little fingers of your non-dominant hand,
hold the last joints of the flex arm, closest to
the dovetail block between the forefinger and
thumb of the same hand. Use the dominant hand
to turn the dovetail block clockwise to tighten
or counterclockwise to loosen (Figure 13). This
action is similar to screwing a nut on to a bolt.
NOTE:
For those surgical procedures which require brain
tissue retraction when a conventional skull clamp
is not used, as in the case of pediatric patients or
severe head trauma, the Budde Halo Brain Retractor
should be used in conjunction with the Budde
Halo Side Rail Support (REF# A1067). Please see
the instruction manual for this product prior to use
(Figure 14).
