Advanced Illuminator Revamps Minimally Invasive Surgeries

A handheld visualization device projects thermally cool, brilliant, white light uniformly throughout the surgical cavity, with the added benefit of a traditional Yankauer suction platform.

The Eigr Saber Waveguide with Yankauer device significantly improves visualization in a variety of surgical applications and specialties, including orthopedic trauma, tumor, hip, and shoulder arthroplasty, and spine, breast, and thyroid oncologic, plastic, and general surgery. The cool on-field and in situ illumination provided by the device also provides a safer surgical environment by virtually eliminating the thermal hazards associated with traditional fiber-optic lighting.


The illumination technology incorporates a proprietary optical waveguide with a complex geometry of integrated microstructures to shape illumination within the operative space. The result is a broad, thermally cool, brilliant, white light that uniformly illuminates deep surgical cavities, providing unsurpassed visualization while virtually eliminating shadows, glare, and thermal hazards. The Eigr Saber Waveguide with Yankauer device is a product of Invuity (San Francisco, CA, USA), and is a single use device.

“Orthopedic trauma represents a substantial market opportunity for us as we address the unmet need for better visualization in these unpredictable and challenging surgeries,” said Philip Sawyer, CEO of Invuity. “This device demonstrates the universal clinical utility of our technology, which improves operating room workflow and surgical efficiency for the many sub-specialties within orthopedics, as well as for many other important surgical specialties.”

“Illumination and suction are equally important to achieve optimal visualization, especially in deep surgical cavities,” said Prof. Herrick Siegel, MD, of the University of Alabama at Birmingham (UAB) Medical Center. “With this new product, Invuity has effectively married two critical technologies and addressed a pressing clinical need for visualization. The Eigr Saber Waveguide with Yankauer is one of the most significant technological advancements in orthopedic surgery this year.”
