基于影像解剖的心俞穴针刺安全深度研究

Study on the Safe Depth of Acupuncture at the Xinshu Acupoints Based on Imaging Anatomy

目的:应用磁共振成像影像,在分析心俞穴解剖结构和进针层次的基础上,测量针刺危险深度,评估针刺安全深度,为心俞穴的针刺安全提供依据,为心俞穴的临床应用提供参考。方法:用磁共振成像扫描仪采集60例健康成年志愿者心俞穴的水平断面影像图,分析解剖结构,测量直刺危险深度,通过危险深度评估安全深度。结果:左、右心俞穴直刺时的平均危险深度值分别为(3.52±0.58)、(3.42±0.63)cm,左、右心俞穴危险深度值差异无统计学意义,危险深度值男性显著大于女性,且与体型相关。结论:体型正常及偏胖者心俞穴直刺安全深度约为3.0 cm,偏瘦者约为2.2 cm;心俞穴常规针刺深度为直刺0.5~0.8寸(约1.5~2.0 cm),具有较高安全性,临床操作中不应超过安全深度,以免发生意外。

Objective:To measure the dangerous depth of acupuncture and evaluate the safe depth of acupuncture on the basis of analyzing the anatomical structure of Xinshu acupoints and the level of needle insertion using magnetic resonance imaging.To provide a basis for the acupuncture safety of Xinshu acupoints,and a reference for the clinical application of Xinshu acupoints.Methods:The horizontal cross-sectional images of Xinshu acupoints in 60 healthy adult volunteers were collected by magnetic resonance imaging scanner.The anatomical structure was analyzed.The dangerous depth of vertical puncture was measured,and the safe depth was evaluated by the dangerous depth.Results:The average dangerous depth values of left and right Xinshu acupoints were(3.52±0.58)cm and(3.42±0.63)cm respectively,and there was no significant difference in the dangerous depth values of left and right Xinshu acupoints.The dangerous depth value of males was significantly greater than that of females,and it was related to body shape.Conclusion:The safe depth of Xinshu acupoints is about 3.0 cm for people with normal body size and overweight,and about 2.2 cm for those with underweight.The conventional acupuncture depth of Xinshu acupoints is 0.5-0.8 cun(about 1.5-2.0 cm),which has high safety.The safe depth should not be exceed in clinical operation to avoid accidents.
