Claims (15)

A system for monitoring a surgical position,
A key with markings that can be attached at a position adjacent to the surgical site and can be recognized on the scan;
A marker fixed and connected to the key;
A non-stereo optical tracker for observing the surgical site and transferring observation data of the surgical site;
Software capable of recognizing the key as a computing device communicating with the tracker and calculating a model of the surgical site based on the scan, key identification and observation data received from the tracker A system including a computing device having:   2. A display system in communication with the computing device, the display system being adjusted to show a current position and orientation of a reference reference to the patient scan during the surgical procedure. The system described in.   The key includes a single reference reference that is adjusted to be secured to the area of the surgical patient, so that the reference reference is at least partially invisible during the surgical procedure, and the marker is Attached to the reference reference at a fixed relative position and orientation of the computing device, wherein the computing device comprises a scan of the patient using the reference reference fixed in the area of the surgical patient. A tracking device includes a processor coupled to the tracker and having a memory and software, and the software program, when executed by the processor, determines a relative position and orientation of the marker based on information from the tracker. And the reference reference for the scan data Having a series of instructions that links the position and direction of the stationary system of claim 1 or claim 2.   The reference reference comprises a specific material that can be clearly identified by X-ray, magnetic resonance imaging (MRI), computed tomography (CT), ultrasonography, or cone-beam computed tomography (CBCT). The system according to any one of claims 3 to 4.   5. The method of any one of claims 1-4, further comprising a number of markers attached to other items, wherein the software program further determines the position and orientation of the number of markers. system.   The system according to any one of claims 1 to 5, wherein the reference reference has a unique shape whose position and direction can be determined from the scan data.   The system according to any one of claims 1 to 6, wherein the reference reference has a label at a predetermined position so that the direction of the reference reference can be determined from the scan data.   8. A system according to any one of the preceding claims, wherein the reference reference is configured and arranged to fit a portion of the patient being scanned.   9. A system according to any one of the preceding claims, wherein the marker has a uniquely perceptible characteristic that can be identified in information from the tracker.   10. The marker according to any one of claims 1 to 9, wherein the marker has a unique shape, and the direction of the reference reference is determined from an image, a continuous image, or the tracker. The described system.   The marker can be identified as a specific code that can be determined from information from the tracker, the specific code being known for its position and orientation relative to the reference reference and determining a fixed specific marker; The system according to any one of claims 1 to 10.   12. Each of the attached tools has an activation point, and the software program determines the position of the activation point relative to the patient scan data. The system described in.   13. The method according to claim 1, wherein the operating point may be one of a drill bit of a dental drill, an endoscope sensor, and a blade of a scalpel. The system of claim 1.   Of the attached tools, one tool has a number of uniquely identifiable markers that are attached to different parts of the one tool, and at least one marker of the number of unique markers is 14. A system according to any one of the preceding claims, wherein the tracker is visible in any direction of the one tool.   15. The system according to any one of claims 1 to 14, wherein the tool is one of a dental drill, an endoscope, a biopsy needle, or a surgical implant.
