Product description
Weil Osteotomy
CHOC developed the twist-off screw for maxillofacial surgery in 1986.
In 1994, CHOC adapted the twist-off screw to the Weil osteotomy.
It is a compression screw with a new type of drill bit allowing it to be used over its whole length.
The twist-off screw is directly screwed in, using the motor, set at a speed of 500 rpm and without prior drilling.
Dimensional characteristics
Weil osteotomy twist-off screws have a diameter of 2 mm, and come in lengths of 11, 12, 13 and 14 mm.
To ensure traceability, the screws are individually packaged individually in double blister packs. The first contains the screw and a sterilisation indicator label. The second blister contains the first blister and five traceability stickers with the screw reference, description and batch number.
The packed screws are then sent to Synergy Health France (MIN des Arnavaux- 13014 MARSEILLE) for sterilisation by gamma radiation according to the ISO 11137-02, ISO 11737-1, ISO 11737-2, EN 552, EN 556 standards and dose mapping. After sterilisation, SYNERGY HEALTH returns the batch of sterilised screws with a certificate of sterilisation by gamma radiation.
The screws in the packaging are then labelled. The label includes the description, the reference, the production batch number, the method of sterilisation, the expiry date, the "single use" and "read instructions before use" symbols, the manufacturer's name and address and the CE 1014 markings.
The screws are packed in boxes identically labelled as above, stretch-wrapped and stored in closed cupboards, away from direct light.
Storage conditions: no special conditions.
