It’s called the Visera 4K Ultra High-Definition (UHD) System, delivering four times the pixels, higher resolution, better light and a wider color gamut than high-definition (HD) displays.

“You can see structures with much more clarity,” said Dr. Petrin, a general surgeon at UPHS-Marquette. “It means surgery is safer, goes faster, and the surgeon’s view is better.”

The equipment is used for laparoscopic, non-invasive surgery.

“We use it for gall bladder and that sort of surgery,” Dr. Petrin explained. “We’ve been using it for about six months now and we’ve all found a difference. It’s a bigger monitor, a clearer image and it makes life much easier for us in surgery.”

UPHS-Marquette is one of the first institutions in the region to offer patients services on the Visera 4K Ultra High-Definition System, which uses the same Sony technology used for the filming of Netflix 4K shows and other television.

It’s now available in the UPHS-Marquette for surgeons to use.

“We use this new equipment every day as it’s in the ORs for us,” Dr. Petrin said. “My take is that it gives us great views, is faster and is safer. I really like it.”

The Visera 4K Ultra High-Definition System allows surgeons to operate with increased precision and confidence. It was created to address unmet needs in surgical imaging by improving visual elements, such as resolution, light, and color — essential for laparoscopic and arthroscopic surgery.

This is achieved through an optimized 4K imaging chain, working seamlessly together to improve visibility and to provide an immersive experience that brings the entire surgical team into the operation.

The Visera 4K Ultra High-Definition System allows doctors to see down to the capillary level, which is important for improved dissection of tissue and evaluating the perfusion of the tissue.

The Visera 4K Ultra High-Definition System provides the UPHS-Marquette surgical teams with:

¯ Ultra-high-resolution images to help identify fine patterns and anatomical structures

¯ Additional light to illuminate bleeding in surgical fields, visualize deep surgical cavities, and enhance the endoscopic viewing experience

¯ More vivid shades of red and yellow for better visualization, allowing the surgeon to observe fine patterns and structures with high precision while delivering higher contrast levels with more detail to support greater accuracy

Minimally invasive surgery brings more efficiency to all hospitals, and it can offer significant improvements in morbidity and mortality over open surgery, with benefits to patients including less post- operative pain and faster recuperation.

Minimally invasive surgery uses small incisions and an instrument with a miniature camera (endoscope), allowing surgeons to see inside the body. Images from the endoscope are projected onto a monitor in the operating room, presenting a clear, magnified view of the surgical site.

Specialized instruments then are inserted through the small incisions, allowing the surgeon to perform laparoscopic or arthroscopic surgery while he or she views the surgical field displayed on the monitor in the OR.

By acquiring the Visera 4K UHD System, with its state-of-the-art electronics and advanced optics, the surgeons at UPHS-Marquette now can see the entire surgical field in 4K UHD on a 55-inch monitor rather than in standard HD currently used by existing systems. Current imaging technologies do not allow the level of magnification, visibility, and color reproduction provided by the Visera 4K UHD System.

With its acquisition of the Visera 4K UHD System, UPHS-Marquette has launched a new chapter in the evolution of minimally invasive surgery — the era of Big Screen Surgery.
