BrainLAB Curved Cup Impactor “Universal”
60907-41
ENGLISH
Overview
The
BrainLAB Curved Cup Impactor
has an offset design that
allows positioning of an acetabular cup implant through a small
incision, as well as transmission of impaction force directly to
the acetabulum.
The
BrainLAB Curved Cup Impactor “Universal”
comes with
exchangeable threaded tips and nosepieces to adapt it for use
with different types of cup implants.
It has a stem mount for attachment of the
StarLock
Instrument Adapter
to enable tracking of the instrument
during computer-aided surgery.

WARNING:
If the BrainLAB Curved Cup Impactor has been damaged
or dropped on the floor, it should no longer be used.
Return the device to BrainLAB for accuracy testing.

Removing and Replacing the Impactor Nosepiece
Overview
The
BrainLAB Curved Cup Impactor “Universal”
nosepieces
and threaded tips adapt the impactor for use with various
implant types.
Before using the impactor, you must attach the correct tip and
nosepiece for the desired implant.
How To Remove the Nosepiece
To remove the nosepiece, gently pry it off the nose of the
impactor (Figure 2).
How To Replace the Nosepiece
To replace the nosepiece, press it onto the nose of the
impactor until you hear a click (Figure 3).
Changing the Threaded Tip
The exchangeable threaded tips of the impactor are designed
for use with specific implants.
Make sure that the implant-compatible threaded tip is attached
to the impactor.
If a non-compatible tip is attached to the impactor, you must
change it.
WARNING:
Be certain that you have attached the correct threaded
tip and nosepiece for the desired implant. Using an
incompatible threaded tip or nosepiece may result in the
implant not coming free of the impactor.
Procedure Overview
To change the threaded tip:
•
Remove the nosepiece
•
Release the ratchet
•
Release the driveshaft
•
Change the threaded tip
•
Re-insert the tip into the impactor
How to Release the Ratchet
Figure 4: Releasing the Ratchet
1 Press the ratchet release lever and lift the tip driveshaft to
pull the ratchet up out of the matching hole.
2 Push the barrel of the ratchet toward the blue knob of the
driveshaft until the ratchet is completely free of the hole and
able to move freely up and down the driveshaft.
•
If you are changing the threaded tip, your next step is to
release the driveshaft.
How to Release The Driveshaft
Figure 5: Releasing The Driveshaft
1 While holding down the driveshaft release lever (2), pull the
driveshaft back (toward the impactor handle) and upward to
free the alignment pins from the notches (3)
2 Lift the driveshaft upwards and bend it at its first joint (arrow)
to disengage the tip from the nose and free the driveshaft from
the impactor body. The tip should now hang free of the nose.
•
Your next step is to remove and replace the threaded
tip.
Removing and Replacing the Threaded Tip
Figure 6: Removing and Replacing the Threaded Tip
1 Unscrew the locking nut of the threaded tip from the
impactor driveshaft.
2 Slide the old tip out of the driveshaft end joint.
3 Introduce the new tip into the driveshaft end joint.
4 Once the tip is fully inserted into the end joint, tighten the
locking nut fingertight to secure the tip.
•
Your next step is to reinsert the tip into the impactor
How to Re-insert the Tip into the Impactor
1 Bend the driveshaft at both joints and insert the tip into the
nose of the impactor.
2 Straighten the driveshaft and press it down toward the shaft
of the impactor until the locking pins click into place in the
alignment notches.
The tip should now project from the nose of the impactor.
3 Attach the implant-specific nosepiece by pressing it onto the
nose of the impactor until you hear it click in place.
The impactor is now ready for you to affix the implant.

Affixing and Locking the Implant on the Impactor
Affixing the Implant
1 If the ratchet is not released, release the ratchet (see above).
2 Introduce the impactor tip into the center (threaded) hole of
the implant (Figure 7).
WARNING:
Some implants and their corresponding nosepiece tips
have a squared or hexagonal interface (Figure 8). Make
sure to correctly orient the interface of both components
when introducing the nosepiece tip of the impactor into
the implant.
3 Screw the impactor tip into the implant by turning the blue
knob on the end of the tip driveshaft clockwise.
WARNING:
Do not overtighten! Overtightening can destroy the
thread of the impactor tip and may make it difficult to
release the implant.
4 With the implant on the impactor tip, re-introduce the
ratchet into the matching hole (Figure 9).
5 Press down gently on the driveshaft to engage the ratchet
(Figure 10). You should hear three clicks.
After three clicks, the implant should still be free to rotate when
the blue driveshaft knob is turned.
Steps Prior to Impaction
The order of your next steps depends on the type of implant
you are using.
If you do not need to turn the implant for alignment, then your
next steps are to
•
lock the implant down onto the impactor.
•
attach the StarLock Instrument Adapter to the impactor
•
introduce the implant into the patient
•
perform impaction
If you are using an implant with screw holes, and will need to
turn the implant to align it, then your next steps are to
•
attach the StarLock Instrument Adapter to the impactor
•
introduce the implant into the patient and align the
screw holes as needed by turning the blue knob
clockwise
•
lock the implant down onto the impactor
•
perform impaction
WARNING:
If there are any difficulties in screwing the implant onto
the impactor, please use your standard impactor and
immediately inform BrainLAB.
To ensure compatibility of threaded tips and nosepieces
with new implants, inform BrainLAB if you receive a new
standard inserter (and new implants).
If trial cups are being used in combination with the standard
cup impactor, use these trials to initially verify compatibility of
threaded tip and nose with the corresponding implant.
Locking the Implant onto the Impactor
Locking the implant down onto the impactor takes the pressure
off the implant threads so that they are not stripped during
impaction.
WARNING:
Be sure to lock the implant to the impactor prior to
impaction. If you fail to do so, the force of impaction may
destroy the threads of the impactor or the implant, making
it difficult or even impossible to remove the implant from
the impactor
.
To lock the implant down onto the impactor, press the
driveshaft firmly toward the impactor body until you can no
longer rotate the implant by turning the blue knob.
Once the implant is locked, you can perform impaction.
