Bending The Quintex® Plate; Positioning And Temporary Fixation Of The Quintex® Plate - B. Braun Aesculap Spine Quintex SC420R Gebrauchsanweisung/Technische Beschreibung

2.3.2 Bending the Quintex® plate
The Aesculap Quintex® plates are supplied as pre-lordosed implants. They
can be bent by means of the plate bender. The bending zone is the area
between the pairs of holes within the bone graft window (window in the
plate).
Note
In order to prevent excessive or insufficient lordosis, the long Quintex®
plates should be bent in steps (one bending zone after another).
CAUTION
Damage to the Quintex® implant due to excessive material stress!
►
Quintex® plates should always be bent in one direction only.
►
Quintex® plates should never be bent back.
►
Always use the plate bender A to bend a Quintex® plate 1.
►
Quintex® plate 1 should only be bent longitudinally and within the
bending zone.
►
Avoid small bending radii, bending back, notching, and scratching of
the Quintex® plate 1.
►
Do not bend in the area of the pairs of holes.
►
To increase the lordosis, place Quintex® plate 1 with the bending zone
positioned centrally between the two upper rolls of the plate bender A,
see Fig. 1.

To decrease the lordosis, place bending wedge 2 over the bending zone,
see Fig. 2.

Note
The area on the instrument on which the lordosis of the plate can be
reduced is labeled "STRAIGHTEN PLATE HERE".
2.3.3 Positioning and temporary fixation of the Quintex® plate
To facilitate intraoperative handling, the Quintex® plate is first temporar-
ily fixated on the vertebral body. This prevents any slipping of the Quintex®
plate during the drilling procedure, and it allows for easier positioning of
the screw holes and insertion of the Quintex® screws.
For the positioning and temporary fixation of the Quintex® plate, the plate
holding forceps O and instrument for fixation pins D are used.
►
Check to make certain that the Quintex® plate is of the correct length.
►
Use the plate holder forceps O to grasp the Quintex® plate 1 by the
outer edge, see Fig. 4.
►
Compress the handles of the plate holding forceps to activate the lock.
The plate holding forceps O now holds the Quintex® plate 1 without
further pressure required on the handles.
►
Quintex® plate 1 is then positioned on the spine, at the required height.

►
As soon as the Quintex® plate 1 is correctly positioned, fix the plate
with fixation pins and further press the handles of the plate holding
forceps O to release the lock.
Note
At least two fixation pins must be inserted for a secure fixation of the
Quintex® plate. Use the instrument for fixation pins D for inserting the pins!
