1, computer-aided surgery system is the early 1990s in Europe and the United States developed countries first into clinical applications for surgeons to provide surgical navigation of advanced medical equipment, surgical navigation system will be the patient's preoperative or intraoperative image data and the patient's anatomical structure on the operating bed accurate correspondence, tracking the surgical instruments and surgical instrument position in the patient's image in real-time in the form of a virtual probe. The system updates the display so that the surgeon knows at a glance the position of the surgical instruments relative to the patient's anatomical structure, making the surgery faster, more precise and safer.
2. Surgical support based on this three-dimensional positional information greatly reduces surgical trauma and minimizes the physical pain of the surgical patient, and recently minimally invasive surgery has also developed rapidly. Since this system can greatly improve the surgeon's surgical accuracy, thus providing better medical services to patients, surgical navigation systems are now in Europe, America and other developed countries' medical institutions.
