用硅橡胶材料制成的柱状输卵管塞，经腹从伞端逆行放入输卵管峡一壶腹部之间，管壁外以7号丝线环扎固定，以探索输卵管可逆性节育法。本法于1979年10月至1984年4月临床试用825例，术后时间最短为8个月，最长为62个月，平均为16.6个月。节育有效率为97.21％。由于本法不切断输卵管，损伤小，故付反应及并发症少。根据动物实验结果，输卵管管壁各层组织病理改变轻微，未见纤维组织增生，故可望取塞后输卵管复通。本组因无复孕要求者，故无复通经验。
Cylindrical tubal stuffing made of silicone rubber material, the abdomen from the umbrella side retrograde into the fallopian tube pot between a pot of abdomen, the wall outside the No. 7 wire cerclage fixed to explore tubal reversible birth control method. The law in October 1979 to April 1984 clinical trial of 825 cases, the shortest postoperative time was 8 months, a maximum of 62 months, with an average of 16.6 months. The rate of birth control was 97.21%. Because this Law does not cut off the fallopian tubes, damage is small, so pay less reaction and complications. According to the results of animal experiments, tubal wall tissue histopathological changes slightly, no fibrous tissue proliferation, it is expected to take the fallopian tube tubal recanalization. This group because of the requirement of no pregnancy, so no experience in re-pass.
