我院从1964年开展针麻胃切除术临床研究以来

在重视针麻适应症、穴位处方、辅助用药、个体差异性和外科手术操作改进外

也很注重针刺方法的研究。起初

安圣承袭传统手法捻针进行针麻中穴位刺激。由于手术是一个较长时间的连续过程

这样就必须对穴位亦要连续不断地进行针刺

以保持继续“得气”

来克服手术创伤引起的疼痛和生理扰乱。这样就要花费很大的人力。为此

设想应用电麻仪代替人工针刺外

再A device with machanical movement imitating acupuncture manipulation has been designed (i. e. ZZ Acupuncture Manipulation Imitating Device or AMID for brief) for clinical in our hospital. This device imitates hand manipulation in the two respects

i.e.twirling of needles and a complicated manipulation consisting of twirling and lift- thrust procedure. A frequency of 180～220 time/min is generally in use. The lift-thrust amplitude is about 2～10 mm

the twirling angle 180～270

and the manipulation of an even speed. Since the end of 1965

381 cases havebeen operated upen for gastrectomy under AMID. The successful rate for 381 cases was 98.4%

with a failure rate of 1.6%

The excellent rates for AMID

AMID + PIEA (para-incisional electroacupun- cture) and AMID + EEN (ear electro-acupuncture) were 75

71 and 76 respec- tively. After x

test has been used for statistical analysis

the difference is not significant. ZZ-AMID is a good start in the reform of acupuncture tools towards their modernization and automation. This device possesses its advantages on stability and uniform speed in twirling

lift-thrust and frequency of stimuli in imitating hand manipulation. So the patients treated with AMID can also experience the same "arrival of qi" (needling reaction

i.e. soreness

nu- mbness and distension) as that of hand manipulation and even a better effect than hand maniputation or electro-acupuncture.
