Advanced Visualization System Aids Spinal Surgery

An Illuminated retraction system enhances visualization and tissue retraction during spinal surgery, including posterior lumbar discectomy and decompression procedures.

The Eigr Taylor Retractor System integrates proprietary Eigr illumination technology into optimized Taylor retractors, making the anatomy appear brighter and sharper while remaining thermally cool. Eigr technology utilizes unique optical structures to control light output to a targeted operative space, by directing light from multiple angles and efficiently managing light across a broad output surface. As a result, shadows are virtually eliminated, as are back reflection, glare, and thermal effects such as overheating. The system includes six retractors in multiple sizes for varying patient anatomies, all ergonomically designed so that surgeons have greater comfort and maneuverability.


Other ergonomically designed features of the system include a blade point that facilitates facet landing; a waveguide fully recessed into the retractor itself that does not obstruct vision or line of sight; a single entry cable with enough space to secure the retractor to the surgical field; and a curved end that facilitates hands free retraction either manually or using weights. The Eigr Taylor Retractor System is a product of Invuity (San Francisco, CA, USA), and has been approved by the US Food and Drug Administration (FDA).

“In the past few months, Invuity has launched several key surgical devices incorporating our Eigr technology that provide critical value to surgeons by enhancing intra-operative visualization, particularly within less invasive procedures,” said Philip Sawyer, CEO of Invuity. “As a result, interest in our spinal products is growing rapidly.”

“I have noted a dramatic improvement in operative field visibility with Eigr technology,” said orthopedic surgeon James Bruffey, MD, of Scripps Clinic (La Jolla, CA, USA). “I am able to see much better and with more definition, even in deeper incisions. Perhaps most importantly, this technology allows me and my assistant to see clearly without the need for a headlight, which makes me more efficient and improves safety.”
