This description is not sufficient for immediate use of implants and instruments.
An instruction into handling these instruments by a surgeon experienced with them is strongly recommended.

Attention:
The following figures show the handling of the screwdriver using the example of an 175 mm screwdriver
shaft and a long holding sleeve. The handling for the 100 mm screwdriver shaft and the short holding sleeve
is the same.

Assembling
1) Connect screwdriver shaft to the handle

2 and 3) Please note the correct alignment of jaw sleeve and screwing sleeve. The jaw sleeve is inserted on the screwdriver
shaft (2). Then the screwing sleeve is pushed up until it snaps in (3).
Attention: For inserting the screwing sleeve touch it only in its front part to avoid compression of the slot.

4) Both parts are now screwed together in front position (screw jaw sleeve while holding the screwing sleeve). The jaws
should finally embrace the socket of the screwing sleeve. Please also consider the section tips.

5) The sleeves can now be moved together backwards to the ”parking position“.

”Parking position“
Tips:
• For aligning the jaw sleeve relative to the screwing sleeve turn in clockwise direction while exerting slight pressure.
• If the jaw sleeve can not be easily connected to the screwing sleeve, slightly press the slot of the screwing sleeve
together.

SDSL-2.1 Intra-operative Handling - Putting on Screws
The angle stable screws are fixed with their threaded heads in the holding sleeve of the screwdriver. Therefore, the
ForceDrive is inserted in the head of the screw and axially aligned with the screw first (1). Then both components of the
holding sleeve (jaw sleeve and screwing sleeve) are moved down together from the ”parking position“ (2). Jaw sleeve
and screwing should be connected via the square connection. (3) Then the screwing sleeve is screwed on the screw head
by means of the jaw sleeve (4). The screw can now be safely removed from the tray (5).
Important:
• Hold the screwdriver as vertically as possible to make putting on the screw easier.
• The screwdriver can only be used for angle stable screws.
• Put the screwdriver only with little effort onto the screw. Otherwise the head thread could be damaged making
the locking effect impossible.
• Stop screwing the holding sleeve on the screw when reaching a distance of 1 mm to the tray! (criterion torque)
• In case of too strong tightening the screwing sleeve could be widened being no longer compatible with the
sleeve system of an aiming device and may be stuck. In this case loosen the holding sleeve until it can be inserted
easily into the aiming device.
• Too strong axial pressure may press the screw in the tray. This can make putting on more difficult and damage the
thread of the screw head.

SDSL-2.2 Intra-operative Handling - Releasing and Locking of Screws
Inserting the screw, care has to be taken that the fixed screw head is released timely. For this it is necessary to build
up pressure to the tip of the screwdriver by means of the jaw sleeve and to hold it while turning until the screw is
released (1). Without this pressure jaw sleeve and screwing sleeve might be unscrewed. Then the sleeve is put back to
the ”parking position“ (2).
Important: Screw placement has to happen manually and carefully. Don‘t turn too fast and too strong until
the head has reached the hole.

SDSL-2.3 Intra-operative Handling - Screw Removal
The screwdriver shaft is connected to the ForceDrive of the screws and the screws are unscrewed for 2 - 3 mm (1). Then
the holding sleeve can be screwed on the threaded head. The connection is achieved by pushing the sleeve forward while
further turning the screwdriver (2). Now the screws are fixed to the screwdriver as during implantation and it is possible
to turn and pull simultaneously (3).
Important:
• Too strong tightening may widen the screwing sleeve, which then is no longer compatible with the sleeve system
of an aiming device and may be stuck. In this case loosen the holding sleeve until it can be moved easily again
within the aiming device.
• Put jaw sleeve on screwing sleeve only in front position.

Intra-operative Handling - Cleaning during Application
It is important to clean the holding sleeve after each application to remove residual blood and tissue. Dried blood
and tissue should be avoided, as it can harm the functionality of the screwdriver.

SDSL-3.1
Post-operative Handling - Preparation
The screwdriver has to be disassembled before cleaning. The two components of the holding sleeve are unscrewed
from each other in front position (1).

Then screwing sleeve and jaw sleeve are removed from the shaft (2). Finally the handle is taken off (3).
Attention: For removing the screwing sleeve only touch it in its front part to avoid compression of the slot.

For information on preparation, desinfection and sterilisation refer to the instruction manual for instruments.

SDSL-3.2 Post-operative Handling - Functional Checks
Check:
• Are the holes free of blood and tissue?
• Is the tip of the screwdriver in good condition (sharp edges) and not twisted?
• Is it possible to put on and to move the screwing sleeve easily?
If necessary widen the rear collet or check the holes for intactness.
• Is it possible to unscrew and to lock the two components of the holding sleeve easily?
