输卵管银夹系列节育术的研究

本研究通过对54例108条输卵管现行银夹上夹后失败病例分析发现,除8条未上夹、4条未夹全、3条管腔未夹闭外,剩余的93条卵管均被夹断或夹破。针对其失败原因,对现行银夹及上夹钳进行改进和研究:1.研究并测量了248条生育二胎以上输卵管形态和直径大小,改单一型号的银夹和上夹钳为大、中、小三种型号,以适用不同粗细的输卵管。2.研制成功了输卵管直径测量器,以此选择适当型号的夹子。3.在上夹钳上装上定位槽和防止银夹后移装置,克服上夹技术操作的盲目性和卡壳现象。经动物实验成功后,在河南8个实验点进行822例的临床实验研究,统一设计和随访,结果实访820例,失访2例,随访率达99.76％。失败1例,绝育有效率达99.88％,无明显并发症。改进后的银夹系列,既保留了现行银夹简便、安全、可逆性好的优点,又克服了上夹技术不易掌握、银夹型号单一的缺点,有效地提高了银夹的成功率。

Study on the Sterilization of Fallopian Tube Silver Clips.

Objective: In order to improve the sterilization efficiency of fallopian tube silver clips, the clips were researched and improved. Method:248 human fallopian tubes diameter were measured by self - improvement fallopian tube measure equipment. According to different diameter of fallopian tube, single model of silver clips and pincers were changed into three models and the pincers were fixed with fix - position - groove and a special equipment which can prevent the clip from slipping. Result: During 3 years of observation on 820 cases who were used with series model silver clip, 819 cases succeeded and 1 case failed. Efficiency rate was 99.88% , no side - reaction and complication were founded. Conclusion:this new model of series silver clip were fit to the different diameter of fallopian tubes. They will be helpful to prevent the phenomenon of fallopian tube's incomplete close or serverence or broken and they can also in-cerease the success rate and reduce side - reaction and complication.
