## Abstract

The advancement of precision surgery demands increased operative accuracy, underscoring the growing importance of three-dimensional (3D) visualization technology as a key tool for overcoming the limitations of two-dimensional (2D) imaging. Over the past decade, this technology has evolved from a post-processing tool into an integrated intelligent platform spanning the entire surgical workflow: preoperative assessment, surgical planning, intraoperative navigation, postoperative follow-up, and teaching/training. This report comprehensively reviews the current applications and key advances of 3D reconstruction, 3D printing, augmented reality (AR), virtual reality (VR), and mixed reality (MR) technologies across major general surgery subspecialties. These include hepatobiliary, pancreatic, gastrointestinal, thyroid/breast, hernia/abdominal wall, organ transplantation, and pediatric surgery. Through in-depth analysis, the review elucidates how these technologies facilitate precision surgery, objectively assesses current technical limitations and ethical/regulatory challenges, and explores future directions driven by artificial intelligence (AI), 5G/6G telecommunications, and digital twin technology.
