Stryker’s PROFESS Navigation System
As technology continues to evolve, more accurate naviation is not only
becoming more accurate, it’s becoming more detailed. Stryker’s PROFESS
Navigation System has been gaining attention from Surgical Products’ readers. It is designed to help surgeons maneuver the nasal cavity through a
tracking algorithm and imaging system.
Q: What was the driving force behind the
development of the PROFESS™ System?
A: The main driving forces for developing the PROFESS
• Increasing number of endoscopic sinus surger-
ies performed annually in hospitals, ASCs, and
• ENT navigation is becoming a standard of care
because it assists the surgeon in clarifying complex
anatomy during sinus surgery.
• Typically, hospitals, ASCs, and office departments
do not have large capital budgets in the ear, nose and
throat (ENT) space.
• The goal with PROFESS is to provide customers
with a cost effective navigation system which is both
accurate and easy to use.
Q: What kinds of challenges did Stryker have in
developing this surgical navigation software?
A: A few challenges included identifying suitable high-performance video tracking algorithms. Real-time video
tracking and 3D reconstruction from video are major
areas of research in the domain of computer vision and
image processing. There are a large number of published,
specialized algorithms and new algorithms are constantly
being developed. The challenge was to identify a robust
algorithm which worked not only under ideal laboratory conditions but also in the operating room (OR) or
surgeon’s office. This includes a large range of different
lighting conditions, effects like motion blur and partially
occluded patterns. The product development team from
Stryker teamed up with Europe’s largest teaching institution to short-list and evaluate potential candidate algorithms. The selected algorithms were then configured and
extensively tested by Stryker to ensure that the accuracy is
equivalent to that of active infra-red tracking systems like
Stryker’s NAV3i® System.
Q: This system offers a variety of features.
What steps can users take to ensure they are
getting the most out of their investment?
A: Customers should take advantage of the small and
portable Stryker ADAPT® Platform, which can be easily
moved from OR to OR. They should also be aware that the
PROFESS software has integrated an intuitive procedural
workflow and even has video tutorials which guides the
user how to set up the system and register the patient.
Q: What are some of the most unique benefits of this system and how will they benefit
Surgical Products’ readers?
A: Many of our consultant surgeons and current customers
highly value the level of accuracy the PROFESS System
provides them throughout the procedure. Some other sig-
nificant benefits of the PROFESS System include:
• Lightweight and ergonomic instrumentation
• Quick and easy patient registration
• Precalibrated tools
• Disposable driven to lower capital costs
