About Tissue Reveal Technology

Minimally Invasive Surgeries (MIS) 

Minimally invasive surgeries encompass surgical techniques that limit the size of incisions needed.  Benefits of this approach include reduced wound healing time, decreased pain and reduced risk of infection. Surgery by definition is invasive, and some operations require larger incisions referred to as "open surgery".   These larger incisions can be painful, become infected and can increase the amount of time spent in the hospital.  

Minimally invasive surgeries such as laparoscopic surgery and robot-assisted surgery have been enabled by camera-based technologies.   The cameras in these systems provide video images during surgical procedures.

As a surgeon is 100% dependent on seeing the surgery via these cameras, their ability to make decisions hinges on good image quality.  As the practice of minimally-invasive surgery has grown, so too has the requirements for camera systems with better imaging.

Improving image quality with Fluorescent Dyes

To improve image quality, manufacturers of MIS equipment have updated their camera systems to include capabilities such as HD Video, 4K Video, 3D Video and Near Infrared  (NIR) capabilities.

While HD, 4K and 3D terminology typically refers to the visible aspect of the video system, NIR is unique in that it refers to the infrared spectrum not viewable by the human eye. 

In NIR video systems, a fluorescent dye such as Indocyanine green (ICG),  fluoresces when the imaging system illuminates the ICG with a specific wavelength.    The NIR mode combined with fluorescent dyes provides surgeons extra information for real-time surgical decision making.

Tissue Reveal Technology: Innovation in Fluorescence

Much like ICG and other fluorescent dyes, Tissue Reveal Technology (TRT) provides fluorescence to improve images and supply additional information to the surgeon.

What sets  TRT apart from fluorescent dyes is that TRT embeds fluorescence into the surgical tool.  This provides fluorescence without the use of dyes and does not require batteries or external power supplies.

Most importantly, TRT has the added benefit of trans-illuminating tissues to provide information such as tissue depth, tissue quality, anatomical borders and sub-surface pathology.

"Anything that makes anatomy 'pop' really makes dissection easier and I 100% believe it is harder to injure something you actually see."

Power Free Fluorescence

Tissue Reveal Technology™ provides battery free and external power free fluorescence when energized by surgical camera systems that utilize near infrared light.

Injection Free Fluorescence

Tissue Reveal Technology™ provides localized fluorescence in surgical instruments and does not require the mixing and injection of  ICG or other fluorescent dyes.

Injection Compatible Fluorescence

All of EndoGlow's Tissue Reveal Technology™ products individually provide fluorescence and can be used in conjunction with intravenous ICG and other systemic dyes.

Fluorescence Without Time Limits 

Fluorescence is available  throughout the surgery without time restrictions, whereas injected ICG is only effective within a short time window before it saturates the image.

Iodine Free Fluorescence

Tissue Reveal Technology™ enabled products provide fluorescence without the use of iodine and can be used in iodine allergic patients.
