The embodiment of the invention provides an operation positioning method and system. The method comprises the steps that according to organ information acquired in advance, a virtual organ image is fit; the virtual organ image is projected to the position above a to-be-operated organ; according to the projection of the virtual organ image, the to-be-operated organ matched with the virtual organ image is subjected to target spot or focus positioning, and an assist doctor positions the target spot or focus rapidly and further determines the operation cut point. According to the method, the virtual organ image is fit, and the virtual organ image is projected to the position above the to-be-operated organ, so that operation doctor can perform target spot or focus positioning to the to-be-operated organ matched with the virtual organ image directly according to the projection, no additional display is required for displaying a virtual navigation chart, and the operation difficulty is simplified.
Description
technical field [0001] The invention relates to the field of augmented reality projection technology, in particular to a surgical positioning method and system. Background technique [0002] The surgical navigation system is used to navigate the surgical instruments used in the patient's operation, which provides convenience for the doctor's operation. The existing navigation system discloses that the patient is in the first coordinate system. The surgical navigation system includes: an image system for capturing images of the patient, the image system has an image intensifier, and markers are arranged on the image intensifier; a positioning module for To identify the marker and obtain the second coordinate system, the second coordinate system is the coordinate system of the image in the image intensifier; the image transmission service module, coupled to the image system, is used to transmit the image of the patient; and the navigation module, coupled to In the positioning...
