ELECTROMAGMETIC NAVIGATION
reliable and easy navigation – since 2006
In endoscopic ear, nose, and throat surgery, spatial orientation is essential for safety and efficiency. Navigation systems support the surgeon by merging preoperative image data with intraoperative instrument tracking, allowing continuous awareness of the instrument’s position within the patient’s anatomy — similar to a GPS system in surgery.
Our ENT navigation system combines sleek hardware, intelligent software, and reusable instruments for precise, efficient, and safe navigation in ENT surgery.


Highlights
- Electromagnetic tracking without line-of-sight restrictions
- 30 times autoclavable instruments
- Compact and lightweight system for easy integration
- Minimized preparation time with intuitive workflow
- Automatic path planning
- Augmented reality in endoscopic video
- Shaver and endoscope navigation
- Full display of instrument geometry
Navigation and tracking platform
The compact design of the navigation and tracking platform allows easy integration into existing surgical towers. The electromagnetic tracking unit offers connection options, which allow simultaneous navigation of up to four instruments at the same time. The system features a small electromagnetic field generator that provides a stable and accurate tracking volume of approx 50 cm^3. It can be integrated directly into the headrest to keep it out of the way during surgery.
- Compact design with small footprint
- Many import options (CD/DVD, USB, Ethernet)
- Field-Generator direcly integrated into the headrest
- Up to four instruments tracked simultaneously

Headrest options
The integrated headrest (left) allows lateral movement of the integrated EM field generator for optimal positioning below the patient’s head.
The universal headrest (right) can be attached to any operating table with standard siderails


Navigated instruments and trackers
Due to the electromagnetic measurement principle the instruments do not require line of sight to the camera.
The instruments and trackers are manufactured with titanium, surgical stainless steel and PEEK. This keeps the instruments rigid and light, allows ergonomic design and fulfulls strict medical material requirements.
- 2.6 meter long connection cable
- Autoclavable and reusable up to 30 times
- Also compatible with the Karl Storz NAV1
Patient-Tracker
The Patient-Tracker can be attached with headband or adhesive tape.

Pointers
The angled and curved pointers are equipped with high-precision micro sensors at the tip for optimal accuracy. They are ideally suited for patient registration – the atraumatic tip can smoothly be dragged accross the patient’s skin during surface matching.

Shaver tracker
The Shaver Tracker enables precise navigation of multiple interchangeable shaver blades and sinus drills during ENT procedures.

Endoscope tracker
The endoscope tracker allows to navigate multiple different endoscope optics. With the 2nd generation of the endoscope tracker augmented reality navigation is possible.

OPTICAL NAVIGATION
The reusable solution for optical tracking



Advanced Technology and High-quality Workmanship
The optical navigation system uses a highly advanced optical measuring system. Tiny, high-precision glass reflectors are mounted on the navigable instruments. The measuring system detects the position and orientation of the glass reflectors in six spatial degrees of freedom with a high degree of accuracy twenty times per second. This allows for real-time representation of instrument position and orientation.
High Precision and Accuracy with Unique Glass Reflectors
The patented glass reflectors are produced via a complex manufacturing process with maximum precision. Each instrument is individually tested for compliance with the required level of accuracy. Due to the special glass and a special coating, small glass reflectors (diam. 5 or 10 mm) can be integrated. This keeps the instruments light and easy to use.
Autoclavable and Reusable Instruments
All instruments and trackers can be sterilised by autoclave and are reusable. Because of the high quality build, there are no special costs incurred by single-use components or instruments that can be sterilised only a few times

Glass reflectors available for purchase
The unique autoclavable and reusable glass reflectors which ERGOSURG integrates in its surgical instruments are also available for purchase separately.
The reflectors are optimized for use with the NDI Polaris optical tracking cameras, but are compatible with most Image-Guided Surgery systems on the market. They come in different diameters (e.g. 5 mm or 10 mm) and coatings (e.g. for 120° or 240° angle of view), which can also be adjusted depending on the application and tracking system.
All reflectors are shipped pre-assembled in sockets (socket thread 4-40 UNC 2-a), using an autoclavable adhesive connection and biocompatible materials. The socket is compatible with the mounting post of the NDI/BrainLab „Passive Marker Sphere“.
The glass spheres reflect much more infrared light than the disposable plastic spheres and thus appear much brighter in the image captured by the optical tracking camera (the 5 mm glass reflectors are approximately as bright as the 13 mm single-use spheres). This allows for higher tracking precision, better handling of trackers with smaller diameter markers and less interferance caused by overlapping markers.
Of course, any contamination can be easily wiped off without having to replace the entire marker.

ENT NAVIGATION SOFTWARE
The ENT navigation software is easy to use, thanks to its intuitive and minimalistic user interface. During the navigated procedure, surgeons have access to supportive features such as automatic path planning, augmented reality and distance control. In addition, the navigation software incorporates the following special features and functions:



SPINE NAVIGATION
for electromagnetic instrument tracking in spine surgery
Joimax® Intracs® em – developed by ERGOSURG
The electromagnetic navigation system provides reliable support for surgeons during minimally-invasive spine procedures. It can be integrated easily into any operating room and connected to the clinic network. Operation of the device is intuitive and user-friendly.
The system is FDA cleared and has won the 2019 Spine Technology Award. Learn more.

Live instrument display without X-Ray exposure
The navigation system displays the position and orientation of all tracked instruments relative to the patient anatomy in real-time. Only two X-Rays are taken at the start of the procedure. They are registered to the patient with a simple registration tool, which can be removed after the registration process. During surgery the view provided by the navigation system is similar to a „live“ X-Ray, but without continuous exposure to X-Ray radiation and with the additional advantage that both anterior-posterior and lateral views are updated simultaneously.
Operational concept with intention recognition
Thanks to a sophisticated user guidance system, the required number of necessary interaction steps is minimal. The system anticipates the interaction the surgeon intends, based on the workflow in Spine surgery, and actively facilitates the operation. No further user input is required during the course of the procedure. The system’s simplicity in control is thereby un- paralleled. Preparation time is reduced to a minimum, and there is no need for a disruptive foot pedal.
Minimal footprint in the operating room
The navigation system can easily be integrated into any equipment trolley and endoscopy tower. This makes setup fast and simple and ensures there is enough space for ideal access to the surgical site.
Integration into clinic network
The navigation system offers a comprehensive range of options for integration into a clinic network and into a networked operating room, like video inputs and outputs and PACS accessibility.

Custom Instruments for navigated sugical procedures
ERGOSURG develops high-precision navigated instruments in-house. In addition to basic tools, like the Patient-Tracker, Sensor-Wire or Probes, customer-specific solutions for instruments such as seekers, suction tubes, biopsy-needles, dilation tools or endoscopes can be developed.



Sensor at the tip for high accuracy
The instrument’s position is measured at its tip, meaning that accuracy is greatest at exactly the point where it is needed most. Measurements at the tip will be highly accurate even if the remainder of the instrument is deformed.
No line-of-sight restrictions
Due to the electromagnetic measuring principle, the instruments do not require a line of sight to an optical camera. They can be handled easily and in an ergonomic fashion.
Autoclavable and reusable instruments
All instruments can be sterilized many times by autoclave. Because of the high quality build, there are no special costs incurred by single-use components or instruments that can be sterilized only a few times.
High-quality material
The instruments are manufactured with state-of-the art, high-quality material, e. g. rigid and light titanium, surgical stainless steel, PEEK or bendable and kink-resistant nitinol. The material-selection of all instruments fulfills strict medical requirements.
High mobility
The extra long connection cable (2.6 m) enables a high degree of flexibility for the OP setup. The navigation system can be positioned at a greater distance from the operating table.
Automatic instrument verification and (optional) calibration
The instrument’s integrity and accuracy are automatically checked during each registration process. Instruments with larger manufacturing tolerances can be calibrated automatically by the navigation software during the instrument registration process. This ensures precise navigation while keeping manufacturing costs low.
