Polaris Vega® ST

Enable new OEM surgical instrument tracking and navigation applications with this versatile optical measurement solution that can be used in almost any operative environment.

Our Versatile Optical Tracker for Diverse OEM Surgical Applications

The Polaris Vega® ST is a versatile optical tracker that can provide trusted measurements in an array of OEM-supported surgical applications, delivering accurate and reliable 3D tracking data. Tracking is achieved via navigation markers that can be attached to OEM surgical instruments such as probes, shavers, awls, drills, microdebriders, and more.

Exclusive to the Polaris Vega ST is an available Radiation Hardening option. The Radiation Hardening option protects the optical tracker from gamma and neutron radiation by way of a shielded processor and modified memory management. This extra protection allows the Polaris Vega ST to be safely integrated into OEM surgical navigation systems and workflows that are used in radiation therapy suites.

More customization options are available to enhance system utility and flexibility. The Positioning Laser assists with positioning the optical tracker and/or surgical equipment within the measurement volume. The Extended Pyramid Volume nearly doubles the measurement volume, which benefits procedures that require a clear view of several surgical instruments at once.
