Navigation

In endoscopy, the visual information provided by the endoscopes combined with the surgeon’s experience and knowledge of anatomy as well as preoperatively generated radiology data sets establish the basis for the operative procedure. However, a prerequisite is – in addition to optimal endoscopic vision – precise orientation within the operative site. Extensive pathologies, scarring or altered anatomical conditions on account of previous surgeries can make it difficult to identify key structures that allow the maintenance of orientation within the operative site. This can affect the quality of the intervention and endanger the safety of the patient.

In such cases, support with spatial orientation is particularly helpful for the surgeon. The optical and electromagnetic navigation systems from KARL STORZ provide surgeons with excellent support in otorhinolaryngology and skull base surgery. During the procedure, the position of the instruments is continuously determined through optical navigation, where glass markers or reflectors are attached to the instruments, or electromagnetic navigation, where micro coils are integrated in the instrument tip.

Years of experience in instrument manufacture ensures the smooth and ergonomic integration of navigated instruments into the clinical routine.

ENT Navigation Software 5.6.0 with Intraoperative Manual Registration Refinement

The new software tool for precise navigation

Manual registration refinement following patient registration using landmarks or surface registration can be activated while navigation is in progress. Navigation is thereby not interrupted and the navigated instrument continues to be displayed. Following activation, an additional landmark can be set to adjust the registration accuracy.

Benefits of intraoperative manual registration refinement:

  • Correction of inaccuracy – particularly depth inaccuracy
  • Intraoperative setting and processing of landmarks without interrupting navigation
  • Eliminates the need to set additional landmarks; these can be set intraoperatively at the position of the site where the inaccuracy is identified
  • Possible to reject manual registration refinement at any time without interrupting navigation – navigation can continue with the initial patient registration
ENT-Navigation-Software 5.6.0
Before: Depth inaccuracy – After: Enhanced accuracy following manual registration refinement

The new ENT Navigation Software Version 5.6.0 is available as an update on CD for all KARL STORZ navigation systems:

  • NAV1™ electromagnetic
  • NAV1™ optical
  • NAV1™ pico

A KARL STORZ contact person will install the update directly on-site and demonstrate the new software tool “manual registration refinement”. All further software tools are retained and will continue to be used.

Following the software update, the new manual registration refinement tool can be used intraoperatively in order to optimize depth!
