本文就作者所研制的内镜微波治疗仪对微波凝固止血作用进行了探索。8条杂种犬实验结果,确认微波凝固之安全性和有效性,被凝固止血的动脉和静脉直径分别为1.5和2mm,微波凝固所引起的凝固性坏死约4周愈合。12例急性上消化道大出血病人,经内镜微波凝固治疗,均血止而无并发症。作者除使用针状电极外,尚首次应用球状电极治疗弥漫性出血性病变获得成功。 In this paper, we developed the endoscopic microwave therapeutic apparatus to explore the role of microwave coagulation hemostasis. 8 mongrel dogs experimental results confirmed the safety and effectiveness of microwave coagulation, coagulation and hemostasis of arteries and veins were 1.5 and 2 mm in diameter, coagulation necrosis caused by microwave coagulation healed about 4 weeks. 12 cases of patients with acute upper gastrointestinal bleeding, endoscopic microwave coagulation therapy, blood without complications. In addition to the use of needle electrodes, the authors first applied spherical electrodes to treat diffuse hemorrhagic lesions.
