Positioning deviation warning method for surgical navigation and system thereof

Abstract

A positioning deviation warning method for surgical navigation and a system thereof are proposed. The positioning deviation warning method for surgical navigation includes configuring a navigation device to monitor a plurality of reference coordinates of a reference; configuring the navigation device to calculate a plurality of first distance values between the reference and the navigation device according to the reference coordinates; configuring the navigation device to extract a portion of the first distance values according to a first time window and calculate a first amplitude of the portion of the first distance values within the first time window; configuring the navigation device to extract a portion of a plurality of the first amplitudes according to a second time window corresponding to a time point and calculate a second amplitude of the portion of the first amplitudes within the second time window, wherein the first amplitudes are corresponding to a plurality of the time points; and configuring the navigation device to determine whether the second amplitude of the portion of the first amplitudes is greater than a predetermined threshold. Therefore, the present disclosure can effectively detect the abnormal deviation of the reference, thereby warning and enhancing safety.
