1. What Are Surgical Navigation Technologies?

A surgical navigation system combines several technologies:

Medical Imaging + Tracking Technology + Navigation Software + Surgical Instruments

The tracking technology is one of the biggest differences between navigation platforms.

A navigation system needs to answer one important question:

“Where is the surgical instrument located compared with the patient’s anatomy?”

Different technologies solve this problem in different ways.

The main tracking approaches include:

1. Optical tracking
2. Electromagnetic tracking
3. Image-based navigation
4. Hybrid tracking solutions

These technologies support applications such as:

• Neurosurgery
• Spine surgery
• Orthopedic surgery
• ENT surgery
• Skull base surgery
• Trauma surgery
• Minimally invasive procedures

2. Optical Surgical Navigation System

What Is Optical Surgical Navigation?

An optical surgical navigation system uses cameras to track surgical instruments and reference devices equipped with optical markers.

The system detects the position of these markers and calculates the location of the instrument in three-dimensional space.

How Does Optical Tracking Work?

The basic workflow is:

Step 1: Camera Detection

A tracking camera detects reflective markers or active markers attached to:

• Surgical instruments
• Navigation probes
