摘要
目的构建人体肺支气管树详细的三维数字化结构,并进行虚拟仿真和3D打印,为纤维支气管镜手术虚拟仿真提供精准的形态学资料。方法选择中国数字化人体CVH1,2,5,6胸部的断层解剖图像,使用AMIRA软件对肺和支气管树进行分割并三维重建,使用Cinema 4D软件平滑,构建交互式3DPDF模型,并进行3D打印,创建虚拟纤维支气管镜手术仿真模型。结果我们构建了4例详细的肺支气管树三维数字化模型,包括3例成人,1例儿童,展示了人体支气管树3~6级分支,4级与6级分支数都为上一级分支数两倍左右,左肺段支气管为8段,6级支气管分支数为63.8±3.6,右肺段支气管为10段,6级支气管分支数为63.8±3.6,左右肺6级支气管数比为0.79。支气管最长长度均位于左叶,儿童管腔直径均小于3例成人的管腔直径。结论支气管树的三维数字化模型、3D打印模型、3D-PDF和手术虚拟仿真软件,提高了对支气管树解剖学和发育生物学的认识。我们认为,左肺的B1+2和B7+8段支气管为单独的段支气管,而不是两段合并的段支气管,此研究为临床解剖学教学和纤维支气管镜手术虚拟仿真提供了形态学基础。
Objective To construct detailed three-dimensional(3D)digital structures and apply to virtual simulation and 3D printing of the human lung bronchial trees,so as to provide accurate morphological data for the virtual simulation of fiberoptic bronchoscopy surgery.Methods The tomographic anatomical images of Chinese Visible Human CVH1,2,5,6 chest were selected.The lungs and bronchial trees were segmented and reconstructed in 3D by using AMIRA software.Cinema 4D software was used to smooth,construct an interactive 3D-PDF model,and perform 3D printing to create virtual fiberoptic bronchoscopy surgery simulation model.Results Detailed 3D digital models of 4 lung bronchial trees were constructed,including 3 adults and 1 child,showing the branches of the human bronchial tree at 3-6 levels,the number of branches at level 4 and level 6 was about twice the number of branches of the upper level.The segment of left lung was 8,the number of bronchial branches at level 6 was(63.8±3.6),the segment of right lung was 10,the number of bronchial branches at level 6 was(63.8±3.6),and the bronchial branches number ratio of the left and right lungs was 0.79.The longest length of the bronchus was located in the left lobe,and the diameter of children’s lumen was smaller than that of three adults.Conclusions The 3D digital model,3D printing model,3D-PDF and virtual simulation software for surgery of the bronchial trees have improved the understanding of anatomy and developmental biology of bronchial tree.We believe that the B1+2and B7+8bronchopulmonary segments of the left lung are separate segmental bronchi,rather than two combined segmental bronchi,which provides morphological basis for clinical anatomy teaching and virtual simulation of fiberoptic bronchoscopy surgery.
