the metaverse system applied to the training of wound location selection for singleport thoracoscopic surgery. The experimental design is two groups of 40 computer tomography located superficially less than 2 cm lung nodule patients, one group uses the metaverse system to let resident physicians simulate the wound position on the digital twin organs of each patient, and the other group does not use it. The investigators will evaluate the surgeon's satisfaction with the surgical wound position and urgicalrelated results (such as surgery time, blood loss, etc.). The investigators expect that the system will help improve the appropriateness of resident physicians' choice of wound location for high-difficulty single-port thoracoscopic surgery, help them cross the first threshold necessary to familiarize themselves with the surgery faster, and accelerate learning.
Aged 18 years or older.
Diagnosed with a lung nodule no larger than 2cm in diameter. The lesion depth must be located within the outer third of the lung.
Scheduled to undergo computer tomography-guided single-port thoracoscopic wedge resection at National Taiwan University Hospital (NTUH) or National Taiwan Cancer Center (NTUCC).
Participants who have provided written informed consent for their imaging data to be used by the team to create digital twin models.
Patients with lesions larger than 2 cm.
Patients not planned for single-port thoracoscopic wedge resection with computed tomography localization.
Patients who have not provided written consent.
Members of vulnerable populations.
Parallel
Metaverse system (Patients)
Other interventionThe experimental group will undergo preoperative training using the metaverse surgical simulation system for 15 minutes before selecting the surgical incision site (this refers to residents receiving the assisted training). The trial process requires participants' consent to provide high-resolution CT images as the basis for reconstructing digital twin organs. Except for the intervention training, the surgery, postoperative care, follow-up, and other treatment processes the participants receive will be the same as those for typical patients.
Metaverse system (Resident Physician)
Other interventionThe participants (residents) will receive 15 minutes of preoperative training using the Metaverse surgical simulation system. They will superimpose the digital twin model onto the patient on the operating table and use the CT cross-sectional matching function within the Metaverse system to locate the lesion. The participants (residents) can use the system to repeatedly simulate incision sites and mark planned entry points on the patient by overlaying the virtual model onto the real patient. Except for the intervention training with the system, the subsequent surgery, postoperative care, follow-up, and other treatment processes the patients receive will be the same as usual.
Operation time
Compare the length of operation time between the experimental group (trained using the Metaverse surgical simulation system for 15 minutes pre-operatively) and the control group. This analysis will assess whether pre-operative simulation training reduces operation time for residents.
Satisfaction Questionnaire for Attending Physicians
To improve the residents selection of wound locations during single-port thoracoscopic surgery, the attending physician will complete a post-operative questionnaire regarding the residents' pre-operative simulation training.
