| 传统的手术导航系统需要术者将视线在显示屏和病灶区之间切换，为了解决这个问题，引入了增强现实手术导航技术。为解决介入类手术中术者无法直接观察到患者病灶与手术器械的相对位置的问题，设计了一种面向介入类手术的增强现实导航系统。术前以Unity软件为开发平台设计虚拟手术路径，并实时显示术中病灶区与手术器械的相对距离。利用头骨和梯台实验对导航系统进行了精度验证，虚拟显示的误差约为3.3 mm。该研究证实了增强现实手术导航在介入类手术术前规划和术中实时引导的可行性。 |

| Traditional surgical navigation systems require operators to switch their eyes between the display screen and the lesion area. In order to solve this problem, augmented reality surgical navigation has been applied. This paper designs an augmented reality navigation system for interventional surgery in order to solve the problem that the operator cannot directly observe the relative position of the patient's lesion and surgical instruments during interventional procedures.The Unity software is used as the development platform to design the virtual surgical path before surgery and to display the relative distance between the lesion area and the surgical instruments in real time intraoperatively. The accuracy of the navigation system was verified using skull and ladder table experiments, and the virtual display showed an error of about 3.3 mm. This study confirms the feasibility of augmented reality surgical navigation for preoperative planning and real-time intraoperative guidance in interventional procedures. |
