The digital operating room can track and store the entire process of patients' surgeries, distribute all video signals during the operation to displays at different locations; realize audio and video interaction inside and outside the operating room to meet clinical teaching needs; and through internal and external networks, assign permissions to achieve live broadcast or rebroadcast of surgeries. Utilizing advantageous technologies such as the Internet, it can fulfill telemedicine requests to upper/lower-level hospitals, conduct surgical guidance, confirm diagnoses to recommend relevant surgical plans, and provide a large ecological network for the entire medical community.
