Highest quality hardware

Whenever medical devices are used in the body, for example as surgical instruments, weight, focus and design play an important role in addition to the material. Easy and safe assembly is just as important as verification of sterilisability, preferably in autoclaves. ERGOSURG offers experienced specialists for metals, plastics and glass including the corresponding cleaning agents and sterilization processes. Focusing on sustainability, we strive to realize reusable instruments while representing the interests of our customers.

Spine Navigation System

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.

Spine Sensor-Wire Spine Patient-Tracker Spine Sensor-Clip Spine Patient-Mapper

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.


ENT Navigation System

optical and electromagnetic navigation - going strong since 2001

Karl-Storz NAV1 - inventend and developed by ERGOSURG

Since 2001 ERGOSURG is developing optical and electromagnetic navigation systems for Karl-Storz SE & Co. KG. Learn more.

Navigation in ENT- and Skull-Base surgery

Interventions in the paranasal sinuses, frontal sinuses, sphenoid sinuses or maxillary sinuses often have to be performed efficiently and in a short chronological order on a day of surgery. A surgical navigation system must be easy to use and intuitively understandable in the respective national language. The preparation time must be short and the instruments must be able to meet the most varied cleaning requirements. Safety features such as distance measurement from risk structures or the deactivation of active instruments prior to contact with the risk structures are just as much a matter of course as convenient intervention planning and documentation.

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.

Cardiac Navigation System

catheter-based navigation for cardiac surgery

The ERGOSURG Cardiac Navigation System supports the surgeons’ spatial understanding during catheter-based minimally invasive cardiac surgeries and is based on a tracked navigation mandrin inserted into supported standard catheters or a direct optical tracking of supported standard guidewires/catheters. It visualizes the position and orientation of theses compatible standard catheters in preoperative planning data and/or intraoperative image data of the patient. The system is intended as a further aid to surgeons between the X-rays taken at regular intervals and therefore it can be easily integrated into the surgical setup and its workflow.
