Embodiment Construction
[0093] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0094] see figure 1 and figure 2 , The surgical navigation system 100 according to the embodiment of the present invention includes a scanning device 10 , a stereo camera 20 , a processing device 30 and a dynamic reference 40 . The scanning device 10 is used to scan the surgical site of the patient before the operation to obtain a scanned image, and the scanned image includes a scanned image coordinate system O. Stereo camera 20 is used for obtaining the real-time image of operation site in operation, and stereo camera 20 comprises camer...

The invention discloses a surgical navigation system and a registration method of a surgical navigation system. The surgical navigation system consists of a dynamic reference unit, a scanning device, a stereo camera, and a processing device. The scanning device is used for scanning an operation part before an operation to obtain a three-dimensional scanning image. The stereo camera is used for obtaining a real-time image of the operation part during the operation. The processing device is used for processing the three-dimensional scanning image and the real-time image, thereby calculating a feature matching point of any point of the real-time image at the three-dimensional scanning image. Therefore, the error caused by the manual operation can be reduced during the registration process. Automatic registration can be realized rapidly even if the part with the disease has a small area, so that the operation time can be shortened and the operation risk can be reduced; and thus the requirement of the minimally invasive surgery can be met.
Description
technical field [0001] The invention relates to the medical field, in particular to a surgical navigation system and a registration method for the surgical navigation system. Background technique [0002] During the operation, it is often necessary to register the actual surgical site and the 3D image of the surgical site obtained by preoperative scanning to guide the operation. In the current registration method of the surgical navigation system, the doctor either manually selects and confirms the feature matching points in the registration process to achieve registration, but the registration accuracy is low due to the doctor's operation error; Area exposure of the patient's surgical site for automatic registration, however, does not meet the needs of minimally invasive surgery. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention provides a surgical nav...
