家兔前肢三阳经五输穴穴区CT三维重建

CT Three-Dimensional Reconstruction of Five-Shu Acupoint of Three Hand Yang Meridian in Rabbit’s Forelimb

摘要: 目的：探讨家兔前肢阳明经大肠五输穴(商阳、二间、三间、阳溪、曲池)、前肢少阳三焦经五输穴(关冲、液门、中渚、支沟、天井)和前肢太阳小肠经五输穴(少泽、前谷、后溪、阳谷、小海)的穴区形态结构。方法：新西兰兔18只，麻醉后进行剃毛。根据定位法取前肢三阳经五输穴，针刺腧穴后留针。经CT行穴区局部薄层轴扫，收集穴区轴位CT断层图像行三维重建后观察。结果：家兔前肢三阳经五输穴针刺时经过的层次有皮肤、皮下组织、肌腱或肌、骨，针体毗邻结构为穴区的神经和血管。结论：穴区CT三维重建可立体显示穴区局部的组织结构，模拟了针刺过程，显示针刺要点，辅助活体家兔腧穴的准确定位。

Abstract: Objective: To investigate the anatomical structure of “Shangyang” (LI 1), “Erjian” (LI 2), “Sanjian” (LI 3), “Yangxi” (LI 5), “Quchi” (LI 11), “Guanchong” (SJ 1), “Yemen” (SJ 2), “Zhongzhu” (SJ 3), “Zhigou” (SJ 6), “Tianjing” (SJ 10), “Shaoze” (SI 1), “Qiangu” (SI 2), “Houxi” (SI 3), “Yanggu” (SI 5), “Xiaohai” (SI 8) in rabbit’s forelimb. Methods: 18 rabbits were shaved after anesthesia. According to the positioning method, take the Five-shu Points of Three Hand Yang Meridian in rabbit’s forelimb. Leave the needle after the needle. CT was used to perform thin-layer axial scanning on the part of the acupoint areas, and the axial CT sectional images of the acupoint area were collected to reconstruct the three-dimensional image of the structure of the acupoint area. Finally, the three-dimensional image was cut and observed. Results: When needling the Five-shu acupoints of Three Hand Yang Meridian in Rabbit’s Forelimb, the layers that pass through include skin, subcutaneous tissue, tendons or muscles, and bones. The adjacent structures of the needle body are nerves and blood vessels in the acupoint area. Conclusion: CT 3D reconstruction technology can stereoscopically display the tissue structure of the acupoint area and realistically simulate the acupuncture process, display the nee-dling points, and assist the accurate positioning of the acupoints in the living rabbits.
