Abstract
A no-touch surgical navigation method for guiding a surgical instrument corresponding to a part of a patient's anatomy is provided. An image registration step is for matching the preoperative implant device planning image and the part of the patient's anatomy via a spatial coordinate transformation relationship. An instrument checking step is for identifying the surgical instrument, and then calibrating a size of the surgical instrument to display an instrument tip mark on the displaying device. An implant device placement selecting step is for moving the surgical instrument by a user, and then the instrument tip mark is synchronously moved with the surgical instrument to select a virtual surgical instrument pattern. A skin incision and trajectory guiding step is for moving the surgical instrument according to a skin incision and trajectory guiding picture so as to move the instrument tip mark close to a planned surgical position.
