Abstract: A method for providing a patient-specific 3D surgical simulation method, according to the present invention, may comprise the steps of: acquiring a scan image including an image of a target object outputted by scanning a patient's body; identifying images of the target object and one or more organs and blood vessels adjacent to the target object in the scan image; generating a first 3D model of a surgical area on the basis of first 3D modeling data of the identified image and second 3D modeling data related to the one or more organs and blood vessels; setting third 3D modeling data and environmental variables for surgical equipment to be applied to the first 3D model; generating a second 3D model for the surgical equipment on the basis of the third 3D modeling data and the environmental variables; and providing a patient-specific surgical simulation on the basis of the first 3D model and the second 3D model.

Abstract: According to an embodiment of the inventive concept, a method for matching an actual surgical image and a 3D-based virtual surgical simulation environment, which is performed by an apparatus, includes setting POI information during surgery at each of surgery steps in a pre-stored surgical image obtained by performing surgery the same as the actual surgical image, matching the POI information with a virtual pneumoperitoneum model of a patient, which is used for the 3D-based virtual surgical simulation environment, the virtual pneumoperitoneum model being displayed on a UI, recognizing a real-time surgery step of the actual surgical image and determining a location of the POI information for the respective recognized surgery step, and obtaining and displaying image information, which is captured by moving a location of an endoscope inserted into the virtual pneumoperitoneum model to the same location as the determined location of the POI information, through the UI.

Abstract: The present disclosure relates to a method and device for recognizing a surgical stage based on visual multiple modality, and may include extracting a plurality of visual kinematics-based indices based on a surgical image including a plurality of frames corresponding to a plurality of surgical stages; obtaining first feature data for the surgical image, and obtain second feature data for the plurality of visual kinematics-based indices; obtaining third feature data by applying a fusion module learned to fuse data to the first feature data and the second feature data; and training a first artificial intelligence (AI) model to recognize each of the plurality of surgical stages based on the third feature data.

Abstract: A method for providing a feedback on a surgical outcome by a computer includes dividing, by the computer, actual surgical data obtained in an actual surgical process into a plurality of detailed surgical operations to obtain actual surgical cue sheet data composed of the plurality of detailed surgical operations, obtaining, by the computer, reference cue sheet data about the actual surgery, and comparing, by the computer, the actual surgical cue sheet data with the reference cue sheet data, and providing, by the computer, the feedback based on the comparison result.

Abstract: The present disclosure relates a device for setting coordinates of each part of an organ of a human body and a method of operating the same. The device according to an embodiment of the present disclosure includes a memory, and a processor that receives organ information on the organ, sets a plurality of isolines connecting a first area corresponding to a first part constituting the organ and a second area corresponding to a second part constituting the organ, and generates organ coordinate system information including isoline information representing the plurality of isolines and the organ information.

Abstract: Disclosed are an artificial intelligence surgical system and a control method therefor. The artificial intelligence surgical system includes a recording device that records a surgical process as a video and inputs the recorded video to a pre-trained artificial intelligence algorithm to determine a surgical stage, and a server that updates the pre-trained artificial intelligence algorithm of the recording device by using the video received from the recording device.

Abstract: Disclosed are an apparatus and method for determining an insertion position of a trocar on a three-dimensional virtual pneumoperitoneum model of a patient. According to the present disclosure as above, the present disclosure may determine a disposition position of the trocar on the pneumoperitoneum model of the patient, which is used in the same surgical simulation as during the actual surgery, the body of the patient, the positions of the surgical tools, the distances to organs, the angles, and the like may be predicted with a high accuracy through the same camera (endoscope) as the actual surgery.
