The Surgical Imaging Navigation System, or – Surgical Navigator – is a space-tracking equipment in real time that tracks, remotely and continuously, surgical instruments and their relation to the anatomical structures of the patient. This is a device composed of: notebook, position sensor, static reference fasteners, static markers, three-dimensional reconstruction software of surgical and medical instruments previously calibrated images with dynamic reference markers.
The tracking system for stereo vision analyzes the images and recognizes image patterns defined as markers. From the recognition of these patterns, the software calculates the spatial positioning generating, in real time, coordinates in axes X, Y and Z.
The result of mathematical calculation of this spatial positioning allows for the continuous display the navigation software, the position of the surgical instrument relative to the patient. In the software, this position is represented by a virtual image that simulates the tip and shaft of the surgical instrument being visible in axial, coronal, sagittal, and the three-dimensional image.
The tomographic images are used as three-dimensional maps; thus directing the entire surgical procedure. The system is also known by the term “Guided Surgery Imaging”.
The Eximius Surgical Navigation Imaging System is indicated for craniofacial surgeries of high complexity. The browser provides the surgeon the spatial location, in real time, the instruments in relation to the anatomical and pathological structures of the patient on the images of computed tomography (CT) or Magnetic Resonance Imaging (MRI).
