evoFix final

evoFix sterile sets for cranial fixation are supplied complete with plates, screws and screwdrivers; sterilised and ready-to-use. The evoFix microplate set consists of three dog bone plates, six screws and a single use screwdriver, making it suitable for most common interventions. The burr hole set contains a fenestrated burr hole cover, five screws and the screwdriver. These sets eliminate the need for sterilising, sorting and selecting the required plates. The cleverly angled design of the case allows the components to be easily seen and the screws can be quickly mounted on the screwdriver. The integrated screwdriver sits securely on the screw head until it is fixed, so the screws cannot fall off. The plates have an integral titanium tab so that the use of additional instruments to aid placement is not necessary. Once the plate is in place, the tab can be easily and conveniently removed.

evoFrame is a sterile, single-use soft tissue retraction system. Stabilised by the use of opposing hooks, the evoFrame can be adjusted in three dimensions to provide the best possible fit. The perfect locking mechanism of the joints, the strong silicon chains and the stainless-steel hooks make it a sturdy system that you can rely on. The silicone chains can also be manually adjusted, giving the surgeon the freedom to adjust to the anatomical site as they wish. The system includes a range of these hooks which provide better visualization of the surgical site as the need of large bulky retractors becomes obsolete. The system also has application across multiple surgical specialities.    evonos produkte evoFrame evonos produkte evoFrame2
