In laparoscopic surgery, the decision of where to set up the port position on the abdominal wall to inject surgical instrument has an impact on the ease of surgery. When setting up ports in 2 places, it is said that the position of the ports and the surgical target part should form close to a regular triangle as much as possible. But it is difficult to confirm the 3D shape of a triangle during surgery and much is dependent on the surgeon's experience.We have developed a navigation system using AR technique. We applied this technology to develop a system that supports to determine port positions. The system overlays the 3D triangle onto the patient's abdominal region as a stereoscopic image.
