X线常规直立后前位检查宫内金属节育环时,认为在耻骨联合上缘之上2—10厘米正中线两旁各3厘米范围内有避孕效果。通过我院多年实践观察,有以下不足之处:①上述常规范围内之节育环,有的并无避孕效果,如子宫右倾时而环却在体中线左侧多属宫壁嵌顿环;相反,有的环在常规范围之外却有避孕效果,如耻骨联合处之横一字形环,由于子宫过度前或后倾而环确在宫内能达避孕目的。②对子宫位置和环形的关系缺乏明确的X 线报告。③直立位检查环的位置和形态改用仰卧位时,环的位置和形态随之变动。因此,从统计学上规定的避孕环正常范围有进一步商榷的必要。鉴于此,我院使用自制的子宫分区器分析节育环的位置形态与子宫位置的关系,掌握其规律性,提高了X 线检查质量。现报告于下:一、子宫分区器的原理、制作和应用产妇随着产次、产伤之增多,宫周诸韧带及盆底支持组织逐渐松弛,产后哺乳期习惯性侧卧和过早负重劳动,或受某些疾病的影
X-ray routine upright after the first inspection of intrauterine metal IUD, that the upper edge of the pubic symphysis 2-10 cm on both sides of the midline have a contraceptive effect within the scope of 3 cm. Through our hospital for many years of practical observation, the following deficiencies: ① the scope of the conventional birth control ring, and some have no contraceptive effect, such as the uterus right when the ring is in the body center line on the left side of the palace wall incarcerated ring; on the contrary, Some ring contraception outside the normal range but there are contraceptive effects, such as pubic symphysis horizontal cross-shaped ring, because the uterus before or after dumping ring and indeed in the uterus to reach the purpose of contraception. ② the relationship between the location of the uterus and the lack of a clear X-ray report. ③ vertical position check ring position and shape to supine position, the ring position and shape change. Therefore, there is a need for further discussion from the statistical range of the normal scope of the contraceptive ring. In view of this, our hospital using the homemade uterine partition device analysis of the location of birth control ring shape and the relationship between the location of the uterus, to grasp the regularity and improve the quality of X-ray examination. Now report on the following: First, the principle of uterine zoning, production and application of maternal With the parity, birth injuries increased, uterine ligament and pelvic floor support organizations gradually loosened, postpartum custodial habitual lying and premature lactation load Labor, or by some diseases
