Development of a Surgical Image Object Display System Using AR Device and Evaluation of Its Depth Perception.

In endoscopic surgery, which has been in increasing demand in recent years, endoscopic images are displayed in two dimensions, so the depth of the image is determined by the surgeon's anatomical knowledge and experience, as well as by palpation with forceps. Therefore, complex surgeries are difficult and time-consuming, and there are reportedly problems with surgical safety and certainty. In order to intuitively recognize the distance between surgical instruments and organs, an endoscopic surgical support system should be developed that provides surgical images that allow real-time observation of the distance between surgical instruments and organs. The purpose of this study is to develop a prototype of an endoscopic surgical support system that provides an optimal field of view and prevents damage to the affected part due to contact between the surgical instruments and the living tissue by intuitively recognizing the distance between the instruments and the organ in real time, and to evaluate depth perception to confirm the effectiveness of the developed system.
