近年来,剖宫产手术逐渐增加和普及,术后近期的再孕既影响产妇的健康又很难给以处理,因此产科医生都在寻求适用剖宫产术后的可靠而简便的避孕措施。近年来,我们设计一种缝环器,此器械带肠线将避孕环缝在子宫壁上,手术后早期虽然子宫颈口未关闭,也可防止避孕环脱落,待产后子宫完全恢复时,肠线吸收,避孕环便可安稳地摆在子宫腔内。自1982年到1983年9月在剖宫产手术同时放置金属避孕环共81例,其中多数是腹膜外剖宫产同时放环,经过两年随访观察,证明效果良好,无并发症。又于1985年初至1986年1月将放环方法进行了改良,共放50例。总计观察131例。
In recent years, cesarean section operation has been gradually increased and popularized. Short-term post-pregnancy pregnancy affects maternal health and is difficult to handle. So obstetricians are seeking reliable and convenient contraceptive measures after cesarean section. In recent years, we designed a sewing machine, the device with a gut of the contraceptive ring sewn on the wall of the uterus, although the cervix is not closed early in surgery, but also prevent the fall of the contraceptive ring until the uterus is fully recovered after the gut Line absorption, the contraceptive ring can be safely placed in the uterine cavity. From 1982 to September 1983 in cesarean section while placing metal contraceptive ring a total of 81 cases, most of them extraperitoneal cesarean section at the same time put the ring, after two years of follow-up observation, the results proved good, no complications. In early 1985 to January 1986, the ring method was improved, a total of 50 cases. A total of 131 cases were observed.
