MAKING THE DIFFERENCE WITH ENHANCED VERSATILITY
The OS 4 surgical platform uses the laws of physics and fluidics to make eye surgery safer, easier and more efficient than it has ever been. The core piece of the device is the three-pump system with vacuum and flow control and the innovative SPEEPMode that ensures highly precise manoeuvres. All instruments are perfectly integrated into the system: cutting-edge LED technology provides for optimum visualisation, the continuous flow cutter ensures traction-free vitreous body removal, and, the fully integrated 532 nm endo laser opens up new possibilities in laser control. Making the difference – with the OS 4 by Oertli.
The platform for all cases
The OS 4 by Oertli is a powerfully efficient all-in-one platform for cataract, glaucoma and vitreoretinal surgery. As a versatile and user-specific OR device, the OS 4 works as the extended hand of the surgeon and carries out his orders and intuitions perfectly.

The power of fluidics
Fluidics can create excellent results, particularly in vitrectomy and in phaco surgery, provided one knows how to master fluidics. Oertli has proved itself as the innovative leader in this sector, which is best demonstrated by its SPEEPMode. The pump system is similar to the peristaltic pump, yet makes use of the advantages of vacuum control. In SPEEPMode, the vacuum is controlled by the surgeon while the flow is held within preset limits. This results in controlled holding power, high efficiency, optimum flow – and thus perfectly precise work in the anterior and posterior segments.

The powerful pedal
The wireless dual-linear OS 4 pedal provides surgeons with a highly sensitive and powerfully efficient control. The pedal comes close to being an ankle joint that absorbs all movements of your foot in a fatigue-free manner. Moreover, it is a reliable control centre with six auxiliary switches, and you can define their commands yourself. Boasting a runtime of up to 50 hours, the integrated high-performance batteries ensure sufficient efficiency for several working days.

GoodLight LED technology
Good vision for the surgeon is essential in vitreoretinal surgery. At the same time, the eye should be strained as little as possible. The light sources that are used in eye surgery are LED, xenon, halogen and metal halide. Oertli relies on the LED technology that boast an optimum mixture of visualization, contrast seeing and safety.

Perfect laser integration
The OS 4 offers a fully integrated 532 nm endo laser of Swiss production. The laser is ready for operation within the shortest time possible and can be controlled directly by means of the dual-linear pedal. This does provide more user-friendliness, a simplified set-up and savings of space and time. Oertli offers a wide range of laser probes suited for the endo laser – straight, curved, directional and steerable.

Accessories of unique quality
As all Oertli devices, the OS 4 surgical platform is a closed system that does not only comprise perfectly suited instruments but also tailor-made device accessories. The large foldable instrument table offers a lot of space and can easily be put aside if you do not use it. The transparent protective cover ensures that the OS 4 is well protected from dust and dirt.
Instruments
With the OS 4, everything that matches comes together. This applies to instruments to a particularly high degree. All instruments are optimally integrated into the surgical system. The hand pieces of high-quality titanium are ergonomic master achievements that demonstrate tailor-made perfection in every respect. The incredibly sharp Caliburn trocar systems ensure excellent wound tightness. And, easyPhaco is a success story for itself.
