4K in the OR

It is a game changer for surgeons in the operating room to be moving from high definition to 4K ultra-high definition (UHD). This is a crucial technological innovation that has helped so many surgeons advance the possibilities of minimally invasive surgery because visualization is a key tool for success in the OR.

Everyone wants the latest and greatest equipment. It makes a surgeon’s job easier, and it provides improved care to the patient. Better visualization provides efficient, successful surgeries that improve the healthcare system entirely.

Will the higher resolution capacity of these 4K devices justify the added costs? A very good question that many doctors and surgeons were asking in the United States when 4K first hit the market.

First, understand that switching from HD to 4K can be a gradual process. That is how it evolved in the United States. It would be a rather large investment to update an entire OR’s infrastructure to 4K. Partial upgrades are how it took hold in the U.S. Monitors, camera systems, camera heads, scopes, etc. These HD products that were upgraded to 4K achieved better resolution.

Every doctor or surgeon would agree that “seeing” is good, but “seeing better” is very good. In the OR, this gives healthcare professionals and unprecedented look into a patient’s body. The OR team can see an unbelievable amount of detail—rich, color-correct images with a greater depth perception. Investing in monitors is a key component of achieving better visualization. The camera systems, camera heads, and scopes are important, but if a premier monitor is disregarded, the image quality is going to be inhibited.

4K products are no longer exclusive to just the United States, nor should they be. AA Medical Store is making 4K equipment affordable. 4K is four times the resolution and we are providing it worldwide for four times less than the price when it first hit the market.


Dr. Akira Dezawa M.D., Ph.D., an internationally respected doctor who serves as a key member of many academic conferences all over the world endorses the use of 4K equipment in the OR and recognizes that it has clear advantages.

Dr. Dezawa states that using 4K equipment allows surgeons to recognize slow tissue movement and judge whether it is a nerve, which is very important when conducting surgeries such as a herniated disc surgery between the patient’s lumbar vertebra (L5) and sacrum.

When it comes to image quality, 4K makes a real difference. Whether you are performing a herniated disc surgery like Dr. Dezawa, or a total knee arthroscopy, high resolution and high contrast on the OR monitor is going to provide extreme benefits.

The Benefits

Light, Color, and Resolution

  • The ability of 4K to deliver clearer images in all light allows for more light to pass through a 5mm scope compared to a 10mm laparoscope.
  • The color that can be seen with the naked eye is what determines visualization. 4K has roughly a billion colors compared to traditional HD that has a little over 16 million colors.
  • Finally, resolution in 4K is quadruple the number of pixels per square inch compared to HD.

The image on the 4K monitor in the OR allows for:

  • Improved efficiency
  • Successful surgeries
  • Quicker surgeries
    • The OR team, patient, and entire health system benefits.
