目的：研制一种新型消化道吻合器---三排钉消化道吻合器械（专利号：2012200583213），并在猪食管胃吻合手术中试验，以明确其相关性能指标，为未来临床应用提供参考。方法以国产两排钉消化道吻合器为对照，设计、制作新型三排钉吻合器并研究其性能。选用12头60 kg 左右家猪，每头先后采用三排钉吻合器、两排钉吻合器，行胃、食管吻合各1次。根据吻合器的不同种类分为2组：A 组（三排钉吻合器）12例和 B 组（两排钉吻合器）12例。结果 A 组与 B 组相比，术中 A 组吻合口内面出血处极少（t＝7．00，P＜0．01），未加固的吻合口在0．5 kg 拉力下，最外圈吻合钉外露很少（t＝6．17，P＜0．01）；A 组吻合钉闭合后为双环形，钉脚的机械强度较大（t＝6．57，P＜0．01）。结论三排钉吻合器在猪食管胃吻合术中的使用效果优于传统两排钉吻合器。

Objective To research a new type of gastrointestinal anastomat -- anastomosis device with three rows of staples (Pa-tent No .2012200583213) ,and clarify its associated functions through esophagogastric anastomosis operations on pigs ,so that we could provide experiences for its clinical application in future .Methods Compared with domestic anastomat with two rows of sta-ples ,we designed and manufactured a new type of anastomat with three rows of staples and researched its function .Choosing 12 do-mestic pigs ,about 60 kg ,gastroesophageal anastomosis was taken twice with each case by anastomat with three or two rows of sta -ples randomly in sequence .According to the different types of anastomats ,cases were divided into two groups :group A ,used anas-tomat with three rows of staples ,including 12 cases of anastomosis ;group B ,used anastomat with two rows of staples ,including an-other 12 cases of anastomosis .Results Compared with group B ,cases of group A have less bleeding sites (t = 7 .00 ,P < 0 .01) . Without reinforcement and with 0 .5 kg of tension ,fewer of outermost staples exposed(t= 6 .17 ,P< 0 .01) .And the shape of used staples of group A is double circles ,which has bigger mechanical strength than that of group B (t= 6 .57 ,P < 0 .01) .Conclusion The function of anastomat with three rows of staples surpasses that of traditional anastomat with two rows of staples in pig esopha -gogastrostomy surgery .
