术式一、在局麻下取三角形切口。设三角形切口各角为A、B、C,三角形底边的中点为D(见图1),将AD设在子宫颈9点和阴道口9点一线上(见图2、图3)。 1、三角形底边切口的位置:用宫颈钳固定好宫颈,并将宫颈向阴道内轻轻推送,此时阴道前后壁最早发生接触处,即为切口位置。术者可用龙胆紫划线做为指标。 2、三角形切口底边的长度:将子宫颈(按时针)9—3点处横径分为四等分,切口最左端应从右侧算起的3/4处(见图4)。 3、三角形之高度:一般在处女膜内2公分即可。
First, under the local anesthesia to take a triangular incision. Set the corners of the triangular incision as A, B, C, the midpoint of the triangle bottom D (see Figure 1), the AD set at the 9:00 of the cervix and vaginal 9:00 line (see Figure 2, Figure 3). 1, the location of the bottom of the triangle incision: cervix fixed cervix, and gently push the cervix to the vagina, this time before and after the vaginal vaginal occlusion occurred at the earliest contact point, that is the incision position. Surgery can use gentian purple crossed as an indicator. 2, the length of the bottom edge of the triangle incision: The cervix (clockwise) at 9-3 points at four points, the most left incision should be counted from the right of 3/4 (see Figure 4). 3, the height of the triangle: generally 2 cm within the hymen can be.
