Innovation in perfection: the 3-pump system in the OS 4

In its OS 4 surgical platform, Oertli has united the very best from two worlds – the peristaltic pump and the Venturi pump. These two pump systems have become established in eye surgery. With the Peristaltic pump, the flow is created mechanically. While the vacuum can only be induced under occlusion and isn’t directly controlled, it boasts the advantage that the flow can be very finely tuned. This creates positive results, especially with maneuvers that require a high degree of delicacy. The Venturi pump, on the other hand, creates the vacuum through an air current. The vacuum is built-up quickly and is linearly adjustable, however, the flow is not directly controlled.

Three pump options are at the surgeon’s disposal: Peristaltic, Venturi and SPEEP. Depending on the situation, the surgeon has the ability to choose the best suited pump. The preferred pump can also be stored for each programme. The SPEEP pump is based on the flow-based Peristaltic pump. Both the flow (up to 60 ml/min) and the vacuum (up to 650 mmHg) can be precisely controlled. The vacuum can also be adjusted, even with occlusion, ensuring safe and stress-free work with maximum efficiency.

Occlusion Mode: Phaco power at the right time

The OS 4 offers three phaco modulations as standard. An additional Occlusion Mode can now be activated for the peristaltic pump system. In Occlusion Mode, phaco power is delivered only when the preset vacuum limit is reached, which means that ultrasound is generated when needed.
