三焦俞影像解剖特点及针刺安全深度研究
Study on the anatomical characteristics of Sanjiaoshu(BL22)image and the safe depth of needling
摘要
Abstract
Objective To analyze the anatomical and structural characteristics of Sanjiaoshu(BL22)by applying magnetic resonance imaging,and to clarify the safe depth of acupuncture for different body types,so as to provide reference and basis for the clinical application of Sanjiaoshu.Method The cross-sectional images of Sanjiaoshu were collected from 203 healthy adult volunteers by magnetic resonance imaging,and the anatomical structure was analyzed to measure the hazardous depth of direct needling and the safe depth.Result The anatomical structure of Sanjiaoshu was similar to that of Shenshu,and the difference was the morphology and size of the lumbar square muscle and lumbar large muscle,and the kidney was located blow and outside the Sanjiaoshu.The mean hazardous depths of Sanjiaoshu were(7.9±1.7)cm and(7.9±1.6)cm for males and(5.5±1.3)cm and(5.5±1.3)cm for females,respectively,with males being larger than females(P＜0.01).Dangerous depth values during direct stabbing of Sanjiaoshu were greater in obese than in overweight(P＜0.01),in overweight than in normal(P＜0.01),and in normal than in underweight(P＜0.01),and there was a significant positive correlation between dangerous depth values during direct stabbing of Sanjiaoshu and body size(P＜0.01).The hazardous depth value during direct stabbing of Sanjiaoshu in overweight and normal was greater in males than in females(P＜0.01).Conclusion The routine depth of Sanjiaoshu is 0.5-1 inch,which is safe.In clinical application,the depth can be increased by 0.5-1 inch according to the patient's body size and gender.Sanjiaoshu is adjacent to the kidney,so it should be avoided to damage the kidney by too deep needling.关键词
