目的探讨应用数字化虚拟技术研究纵形断指的临床解剖学特点。方法将虚拟手模型三维图形文件导入Mimics软件,利用Simulation模块的正交立体切割工具,对重建后的手分别沿指体侧中线、指体侧中线偏背侧、指体侧中线偏掌侧、指体掌(背)侧中线截面进行切割,并对其解剖学形态进行观察测量。结果建立了基于解剖结构的可视化手模型并精确显示其主要解剖结构,各结构可单独、联合显示,可任意旋转缩放,模型透视及多剖面显示。切割截面骨骼、动脉、神经、肌腱等结构呈现纵向斜形,动脉管腔截面可见短斜形、长斜形、类圆形等多种形式。各平面切割缺如情况不一,呈现多平面,多形状,多节段,空间立体分布特征。切割截面形态与伤指实际情况基本相符,能真实反映断指伤情及损伤特点。结论数字化虚拟技术可较真实的虚拟再现纵形断指伤情,能为纵行断指伤再植研究提供临床应用解剖学依据。
Objective To investigate the clinical anatomical characteristics of longitudinal index finger using digital virtual technology. Methods The 3D model of virtual hand model was imported into Mimics software. Using the orthogonal cube cutting tool of Simulation module, the reconstructed hand was analyzed along the midline of the midline, the midline of the midline, the dorsal side of the midline, Refers to the body palm (dorsal) side of the midline section for cutting, and its anatomical observation and measurement. Results A hand model based on anatomical visualization was established and the main anatomical structures were accurately displayed. The structures were individually and jointly displayed, freely scrollable, model perspective and multi-sectional display. Cutting cross-section bones, arteries, nerves, tendons and other structures showed a longitudinal oblique, arterial lumen cross-section can be seen short oblique, long oblique, round and other forms. The lack of plane cutting in different situations, showing multi-plane, multi-shape, multi-segment, spatial distribution of three-dimensional characteristics. Cutting section shape and the actual situation of the injured finger basically consistent, can truly reflect the broken finger injury and injury characteristics. Conclusion The digital virtual technology can reproduce the virtual longitudinal injury of the longitudinal index finger severely and provide anatomical basis for the study of longitudinal replantation of severed finger.
