经过对1,200例手术的临床实践和追踪观察,成功率达88％以上。粘堵药物一氰基丙烯酸正丁脂(代号:504),为无色透明液,遇水迅速聚合成块(碱性环境聚合更快)。聚合时放出一定热量,粘合力强,不易被人体吸收,无毒性。方法将聚乙烯或聚氯乙烯制成喇叭型粘堵头轻放入宫腔内注生理盐水于宫颈口至流出水为止(即示宫腔内已注满水),记录宫腔容积。用粘堵器在子宫角部寻找输卵管开口,术者初步判断为管口,便固定粘堵器轻压其上,再注入盐水,如注入之水量超过原宫腔容积(一般5—6毫升),而宫颈口仍无液体外流时(示盐水进入腹腔),则可确定粘堵器头正对着输
After 1,200 cases of clinical practice and follow-up observation, the success rate of 88% or more. A blocking drug - n-butyl cyanoacrylate (code: 504), a colorless transparent liquid, water quickly aggregate into blocks (alkali environment polymerization faster). Aggregate release a certain amount of heat, strong adhesion, not easily absorbed by the body, non-toxic. Methods Polyethylene or PVC made of trumpet sticky plug gently into the uterine cavity injection of saline in the cervix until the effluent (that shows the intrauterine has been filled with water), recording the volume of the uterine cavity. Stick with the plug in the uterine horn looking for tubal openings, the surgeon initially determine the nozzle, it fixed pressure occluder gently pressure on it, and then injected saline, such as the amount of water injected into the original volume of the uterine cavity (usually 5-6 ml) , While the cervix is still no fluid outflow (show saline into the abdominal cavity), you can determine the tack plug head is facing the loser
