Spine surgery guidance tools provide different kinds of information about anatomy and instrument position. Their operating principles shape how they fit into the procedure.
Guidance technologies in spine surgery range from image-based navigation to probes that sense local tissue properties. Both support the surgical workflow, but they provide different information.
Image-based navigation
Image-based systems relate tracked instruments to anatomical images. Registration aligns the patient with the image dataset so the system can display the instrument position in that reference.
Tissue-sensing probes
Some probes measure electrical properties of tissue and translate changes into audible or visual signals. This local feedback differs from displaying an instrument on an anatomical image.
The distinction matters when comparing product specifications: a sensing probe and an image-based navigation platform have different equipment requirements and outputs.
Specifications that define workflow fit
- Guidance method and signal output
- Imaging and tracking requirements, where applicable
- Instrument dimensions and intended use
- Single-use or reusable designation
- Sterile presentation or specified reprocessing method
Product instructions define setup, handling and compatible components. The surgeon selects the guidance approach within the clinical plan.
Advanced Modern Sciences lists Spine Guard (France) among its partners for navigation probes for spine surgery. Comparing these products starts with the specific probe’s sensing method and intended use.
Common questions
How does image-based navigation work?+
It relates tracked instruments to anatomical images through patient registration. The display shows instrument position within that image reference.
What information does a tissue-sensing probe provide?+
It detects local tissue properties and converts changes into signals defined by the device design.
Which specifications belong in a probe comparison?+
Compare intended use, sensing method, dimensions, compatible components and sterile handling requirements.
