Phacoemulsification OS3 - Fair

Phacoemulsifier OS 3 Oertli - Precision and Efficiency for Advanced Cataract Surgery

The OS3 fluidics system stands in a class of its own. A peristaltic pump of the latest generation, with fine control, and a genuine Venturi pump are at your disposal at all times and can be employed via the TwinVac cassette alternately within seconds. Posterior segment surgeons can now use the advantages of direct flow control with the peristaltic pump to carry out the most difficult manoeuvres, and thanks to easyPhaco and high fluidics settings, cataract surgeons experience a quantum leap.

The surgeon decides how he or she wants to operate – not the machine. Therefore, certain preferred parameters can be set in the ParaProg background programme. With the programmable dual-linear pedal, independent control of individual values such as flow, vacuum, power and cutting rate are possible in a very precise way. The operator can give numerous commands to change functions or values by foot. Therefore, he or she can fully concentrate on manipulation in the eye.

From the sterile environment, the assistants have full access to the whole system at any time. The complete control panel can be put on the instrument table. There are no essential functions and displays that require you to move towards the device.

Proven technology, clearly structured software architecture, the preference given to uncomplicated concepts based on fundamental physics and mechanics, and the high quality of the performance have resulted in the truly extraordinary reliability of OS3 – a thoroughly sophisticated product at the cutting edge of technology.

Despite its compactness and lightness, OS3 illustrates the effectiveness of a highly developed technique that is fully at the disposal of the operator. There are clear and clearly arranged connections, fine, tangible keys which invite you to touch them, with bright and clear-cut displays. All details are well presented, but without any frills, and the equipment stands on solid feet. OS3 brings a fresh note to the OR environment and places people at its heart.

Operating more easily, more safely, and more efficiently was the principle when developing OS3. Renouncing unnecessary frills, but with full concentration on the essential. Fast, simple, and direct control without complicated menu navigation and the effort of programming, but immediate access to the desired function instead. The dual pump system is operated via the patented TwinVac cassette, which simultaneously works in the anterior and posterior segment and makes it possible to switch within seconds between Venturi and peristaltic.

OS3 is extremely reliable. Thanks to the embedded micro-controller technique, the device – after a power cut – immediately reverts to its previous function again, ready to operate. The complexity of micro-computer operation systems, which are susceptible to disturbance, can thus be avoided. This explains the extraordinary stability of OS3 software control. When there is a drop in air pressure, OS3 switches to Peristaltic and continues to operate. Voltage fluctuations between 90 V and 250 V are no problem. Two independent light systems provide safety in case of lamp failure.

Fluidics is the key element of modern surgery platforms. It is present everywhere, in the anterior and in the posterior segment! The insufficient fluidics of conventional techniques produce stress and complications. Therefore, Oertli has taken a new direction with Best Practice Fluidics, and fluidics has thus become a friend of every surgeon, a truly active and supporting function. The OS3 dual pump system enables a choice between a genuine Peristaltic and a genuine Venturi pump at any time. The choice can be made using the pedal whilst operating, exactly at the moment when a critical operating step is required; e.g., when inducing a PVD or when peeling is taking place in retina surgery, or when cleaning the capsule in cataract surgery.

Contrary to popular belief, the latest-generation peristaltic pump allows for direct and extremely precise flow control, which is unaffected by the cutting rate and the duty cycle. This capability offers unprecedented precision in critical maneuvers such as inducing a PVD, working on the base of the vitreous body, and peeling membranes. Best Practice Fluidics with direct flow control enables automatic control of flow and occlusion vacuum independently of each other.
