True Flow Control

With its fluidics concept that makes excellent use of physics and fluidics, Oertli has led flow and vacuum control to perfection. Thanks to True Flow Control, you can finely tune the flow with the dual-linear foot pedal in an incredibly subtle way – resulting in impressive precision and a high occlusion vacuum. Thus, full control in every possible situation has been achieved, for example in peripheral vitrectomy, detached retina, shaving or peeling. Neither additional software manipulations nor a duty cycle control are necessary any longer.

In vitreoretinal surgery, Oertli has already set standards with its dual-pneumatic Twinac drive that boasts great cutting force and traction-free high-speed cutting. Next, the Oertli continuous flow cutter was a significant quantum leap. The continuous flow cutting concept allows for continuous flow without any fluctuation. While with a standard cutter, the flow is interrupted with ever cut, the continuous flow cutter ensures traction-free and precise flow as well as rapid aspiration and ideal portioning of the vitreous body for removal. The new SPEEP pump with new fluidics make flow and vacuum a dynamic yet directly controllable tool for unimaginably precise and efficient vitreoretinal surgery.

Features and benefits of the Continuous Flow Cutter

  • Traction free and continuous aspiration supported by unique SPEEP pump
  • Close cutting at the tissue through minimal port-to-surface distance
  • High efficiency with pneumatic push-pull priniciple invented by Oertli
  • Perfect portioning of vitreous body thanks to strong holding and cutting force
  • Doubled cut rates up to 10'000 cpm
