【摘要】：目的探讨利用粉末堆积打印技术制作的高仿真3-D颞骨模型在解剖技能训练及模拟手术中的应用。方法利用高分辨率CT获取活体颞骨断层图像(正常人2例,慢性中耳炎患者2例),数据导入Mimics软件行图像分割及颞骨三维重建,以石膏粉末为原料,利用粉末堆积快速成型技术打印出颞骨模型,重要解剖结构与组织(听骨链、面神经、位听器、炎性渗出及胆脂瘤等)以不同颜色打印,并在显微镜下进行手术演练。结果颞骨模型的硬度与人骨相近,模型表面及内部骨性标志明显,解剖精确度高,钻磨触感接近真实,满足颞骨解剖技能训练及模拟手术的要求。结论利用粉末堆积打印技术能制作出仿真度更高、更接近实际人体解剖结构的颞骨模型,帮助临床医生在术前全面了解患者的颞骨及周围组织解剖结构与病变情况,制定和优化手术方案,减少并发症。
[Abstract]:Objective to explore the application of high simulation 3-D temporal bone model made by powder piling printing in anatomical skill training and simulated surgery. Methods High-resolution CT images of temporal bone were obtained from 2 normal subjects and 2 patients with chronic otitis media. The data were imported into Mimics software for image segmentation and 3D reconstruction of temporal bone. Gypsum powder was used as raw material. The temporal bone model was printed by powder stacking rapid prototyping technique. The important anatomical structures and tissues (auditory chain facial nerve position audiometer inflammatory exudation and cholesteatoma etc.) were printed in different colors and operated under microscope. Results the hardness of the temporal bone model was similar to that of the human bone. The surface and internal bone markers of the model were obvious, the anatomical accuracy was high, and the sense of touch was close to the reality, which met the requirements of the temporal bone anatomical skills training and simulated surgery. Conclusion the technique of powder piling printing can make the temporal bone model which is more realistic and closer to the actual anatomical structure of human body. It helps clinicians to understand the anatomical structure and pathological changes of the temporal bone and surrounding tissues of the patients before operation. Develop and optimize surgical procedures to reduce complications.
