作者介绍了一种新型含铜环形IUD,即Mer-chant′s Copper Coil(MCC)。MCC是由聚乙烯制成的环(1.8cm),其上缠绕铜丝(0.2mm),铜的表面积为251mm~2。MCC保持在子宫的中心部位,使广泛的子宫内膜与铜的表面接触,可有效地防止宫内或宫外妊娠。在子宫腔中MCC的末端有重叠,可使其得到调节,适合于任何子宫腔。MCC无突起的末端,减少了子宫有力收缩时穿孔的危险。放置时可采用直径3.6mm的管状放置器,很容易地将MCC呈线形置入宫腔。为了选择适合于子宫腔大小的IUD,放置前用Kurz的宫腔测量计或Hasson翼状探针测量宫腔大小。共有244例妇女要求采用MCC,年龄为20～40
The authors describe a new copper-containing ring IUD, Mer-chant’s Copper Coil (MCC). The MCC is a ring made of polyethylene (1.8 cm) on which a copper wire (0.2 mm) is wound with a copper surface area of 251-2 mm. MCC remain in the center of the uterus, so that a wide range of endometrial and copper surface contact, which can effectively prevent intrauterine or extrauterine pregnancy. There is overlap in the end of the MCC in the uterine cavity to allow it to be adjusted for any uterine cavity. No protruding ends of the MCC reduce the risk of perforation when the uterus contracts strongly. Placement can be used when the 3.6mm diameter tube placer, the MCC was linear into the uterine cavity. To select an IUD that is appropriate for the size of the uterine cavity, uterine size is measured with a Kurz uterine cavity gauge or Hasson wing probe prior to placement. A total of 244 women requested MCC, aged 20-40
