NAV1® SinusTracker™

The innovative planning software for new routes in FESS surgery

The NAV1® SINUSTRACKER™ planning software enhances the KARL STORZ NAV1® ELECTROMAGNETIC system with the automatic planning of access paths in paranasal sinus and skull base surgery. On the basis of a preoperatively set starting and destination point in the patient’s radiological data, the software allows the surgeon to determine a precise access path that is specially adapted to the individual anatomic structures of the patient.
The physician then reviews and modifies the suggested access path at his/her discretion. Intraoperatively, the selected route is visualized on the navigation screen so that the actual position in the site is under constant control.

Benefits of the NAV1® SinusTracker™

  • Multiple Path Planning enables the preoperative planning and naming of up to eight access paths and alternatives
  • Intraoperative visualization and control of access paths
  • Less preoperative planning required thanks to automatic preplanning
  • Flexible, pre- and intraoperative adaptation of the access path possible

NAV1® Endoscope Tracker

Augmented FESS endoscopy with the new electromagnetic navigated endoscope adaptor

Using augmented endoscopy, which was specially developed for the NAV1® SinusTracker™, the real-time endoscopic image can be enhanced with information obtained from the preoperative virtual planning of the access route. Adaptor is used in conjunction with KARL STORZ HOPKINS® telescopes with 0°, 30° or 45° directions of view for augmentation. The position and direction of view of the employed telescope is displayed in the radiology images in such a way that the endoscopic image can be precisely assigned to the exact location in-situ.

Benefits of augmented endoscopy

  • Possible to display planning elements in the standard endoscopic image
  • Visual navigation of non-navigated instruments along the preoperatively planned route
  • Spatial mapping of the direction of view and the position of the telescope in the site

EM Shaver Tracker

The new EM shaver tracker allows the electromagnetic navigation of motorized standard shaver blades and sinus burrs. 
Benefits of EM-navigated shaver blades and sinus burrs:

  • Reusable tracker (up to 30 applications guaranteed) 
  • Customary handling of the shaver blades and sinus burrs by attaching the shaver tracker to the rotary wheel of the blade or burr
  • Automatic detection of rotation
  • Visualized geometry and ablation radius of the shaver attachments
  • Precise locking to shaver blade to achieve greater accuracy

NAV1® optical

The optical navigation system for FESS and ear surgery

Benefits of NAV1® OPTICAL

  • Seamless integration as the basic unit can be attached to a ceiling supply unit or equipment cart
  • Very economic thanks to patented autoclavable and therefore reusable glass spheres and instruments
  • User-friendly interface thanks to clearly defined control elements and menu navigation
  • Wide range of conventional as well as motor-driven navigation instruments in the proven KARL STORZ quality
  • NAV1® ELECTROMAGNETIC module enables customized enhancement thanks to optical measurement technology
  • Intraoperative re-registration to correct deviations, particularly those in depth
