In minimally invasive spine surgery (MISS), where the surgeon cannot directly see the patient's internal anatomical structure, the implementation of augmented reality (AR) technology may solve this problem.
We combined AR, artificial intelligence, and optical tracking to enhance the augmented reality minimally invasive spine surgery (AR-MISS) system. The system has three functions: AR radiograph superimposition, AR real-time puncture needle tracking, and AR intraoperative navigation. The three functions of the system were evaluated through beagle animal experiments.
The AR radiographs were successfully superimposed on the real intraoperative videos. The anteroposterior (AP) and lateral errors of superimposed AR radiographs were 0.74 ± 0.21 mm and 1.13 ± 0.40 mm, respectively. The puncture needles could be tracked by the AR-MISS system in real time. The AP and lateral errors of the real-time AR needle tracking were 1.26 ± 0.20 mm and 1.22 ± 0.25 mm, respectively. With the help of AR radiographs and AR puncture needles, the puncture procedure could be guided visually by the system in real-time. The anteroposterior and lateral errors of AR-guided puncture were 2.47 ± 0.86 mm and 2.85 ± 1.17 mm, respectively.
The results indicate that the AR-MISS system is accurate and applicable.
在微创脊柱手术（MISS）中，外科医生无法直接看到患者的内部解剖结构，增强现实（AR）技术的应用可能会解决这一问题。
我们将AR、人工智能和光学跟踪相结合，以增强增强现实微创脊柱手术（AR-MISS）系统。该系统具有三项功能：AR射线照片叠加、AR实时穿刺针跟踪和AR术中导航。通过比格犬动物实验对系统的这三项功能进行了评估。
AR射线照片成功叠加在术中实时视频上。叠加后的AR射线照片的前后（AP）误差和横向误差分别为0.74±0.21毫米和1.13±0.40毫米。AR-MISS系统能够实时跟踪穿刺针。实时AR针跟踪的AP误差和横向误差分别为1.26±0.20毫米和1.22±0.25毫米。在AR射线照片和AR穿刺针的帮助下，系统可以实时直观地引导穿刺过程。AR引导穿刺的前后误差和横向误差分别为2.47±0.86毫米和2.85±1.17毫米。
结果表明AR-MISS系统准确且适用。
