Development of new 4K-3D video microscope with high-resolution and deep depth of focus

Abstract

We recently developed novel 3D-4K fluorescent video system, which enables for us to resect abdominal organs finely as well as perform anastomoses of tiny vessels, bile ducts and pancreatic duct. The surgical field is displayed on a screen via a high-resolution (4K) 3D-camera that formerly required use of a magnifying surgical loupe. Our novel system is useful for the following points. 1.The operator and assistants have the same field of view in heads-up surgery, which indicates this system is suitable for surgical education. 2.The focal depth is not greatly disturbed by pulsing blood vessels or movement such as respiration.3. Using this system, surgeons may tolerate long operative times with “Head-up” status, which will not injure the surgeon’s neck.
