摘　　要：目的采用计算机三维设计和增强现实(AR)探讨经皮胸椎椎弓根通路技术,以期提高胸椎经椎弓根穿刺入路技术的安全性。方法胸椎CT图像经计算机三维重建后测量E角和F角空间线面夹角的准确数值,采用快速成型技术打印胸椎模型。模拟穿刺后将模型置于G臂机获取X线图像并比较分析。结果E角与横断面置钉角(TSA)角差值为0.87°。F角与矢状面置钉角(SSA)角差值为1.20°。结论E角和F角的平面线线夹角与空间线面夹角存在差异,计算机手术辅助设计及AR技术辅助胸椎经皮椎弓根穿刺技术更为精准。Objective Computer three-dimensional design and augmented reality(AR)are used to explore the percutaneous thoracic pedicle access technology,in order to improve the safety of the thoracic spine transpedicular puncture approach.Methods The CT images of the thoracic spine were reconstructed by the computer to measure the accurate value of the angle between the E angle and the F angle.The thoracic spine model was printed using rapid prototyping technology.After the puncture simulation,the model is placed on the G-arm machine to obtain X-ray images and compare and analyze them.Results The difference between the E angle and the TSA angle is 0.87°.The difference between the F angle and the sagittal plane nail angle(SSA)angle is 1.20°.Conclusion There is a difference between the angle between the plane line of the E angle and the F angle and the angle between the space line and the plane.The computer-assisted design and AR technology-assisted thoracic spine percutaneous pedicle puncture technique is more accurate.
