Abstract: A dynamic reference deviation detecting method is used for detecting a deviation of a dynamic reference coordinate system. A coordinate detecting step is for detecting and recording a first initial coordinate and a second initial coordinate. A first coordinate variation calculating step is for calculating a difference between a first instantaneous coordinate and the first initial coordinate to obtain a first difference value. A second coordinate variation calculating step is for calculating a difference between a second instantaneous coordinate and the second initial coordinate to obtain a second difference value. A relative coordinate variation calculating step is for obtaining a relative difference value. A dynamic reference deviation determining step is for determining whether or not the dynamic reference coordinate system is deviated according to the first difference value, the second difference value and the relative difference value.

Abstract: A pre-planning interface displaying step of a method for verifying panoramic images of implants is for displaying a picture, a menu and a cursor on a screen. An implant trajectory pattern adding step is for moving the cursor to select an implant adding item by a user and then generating the implant trajectory pattern in the picture. An implant trajectory pattern adjusting step is for controlling the cursor to adjust a position of the implant trajectory pattern and then move the implant trajectory pattern from a starting position to a target position in the picture. A panoramic image verifying step is for rotating the surgical site pattern around the implant trajectory pattern at a viewing angle according to the target position and the implant trajectory pattern as a central axis, and the viewing angle is greater than 0 degrees and smaller than or equal to 180 degrees.

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.
