The Rectangular Drill/Screwdriver has been developed for predrilling and screw insertion on mandible and midfacial fractures with minimal invasive approaches. Its flat head (6.5 mm) and low overall height allows for intraoral fracture treatments especially when endoscopically supported. Among various possible applications are plate fixation on subcondylar fractures and bilateral sagittal split osteotomies (BSSO).
The Rectangular Drill/Screwdriver is offered with a Minimodule including screwdriver shafts (StarDrive, Cruciform) and drill bits. It has inserts for screw sizes of 1.5 mm/2.0 mm and 2.4 mm. All parts can be picked up and exchanged quickly, which makes the device easy to clean. For better visibility and less irritation of soft tissue the screwholder can be turned at an angle behind the head.
By removing the screwholder insert or the complete screwholder and connection of a conventional drive unit at the handle the device can also be used for rectangular predrilling.
The device is equipped with an intracoupling according to ISO 3964/ EN 23 964 (maximal output: 5.000rpmi). The gear ratio is 1:2.
