1. An augmented reality (AR) assisted surgical system comprising:
a three-dimensional spatial virtual surgical treatment plan (SVSTP) for mixed or virtual reality; and
multiple AR interfaces (ARIs), including a first ARI and a second ARI, at least the first ARI and the second ARI configured to overlay the SVSTP onto a surgical site to generate an overlaid SVSTP viewed from the first ARI and an overlaid SVSTP viewed from the second ARI, wherein the ARIs are positioned at different angles and are configured to exchange three-dimensional coordinate information with each other, wherein the exchanged coordinate information is used to align different surgical view angles to superimpose at least the overlaid SVSTP viewed from the first ARI with the overlaid SVSTP viewed from the second ARI to generate a superimposed SVSTP, which is used to display information on at least the first ARI to guide a surgical instrument in three dimensions, and to provide an unobstructed view of the surgical site and reduce parallax and occlusion errors during surgery.
