胎儿镜是近几年研制的获取胎儿情报的重要手段之一,能在直视下取得胎儿情报。约在30年前,Westin 将麦卡锡广视野膀胱镜经宫颈管插入宫腔,在直视下成功地观察和拍照妊娠子宫内人胎儿。他观察3例(全麻2例,局麻1例)宫内胎儿,但因未能插入羊膜腔内,视野狭窄,诊断价值不大,未能继续试验。20年后,Valenti,用小儿膀胱镜(直径约6mm)经腹壁观察和拍照妊娠子宫内胎儿获得成功;并从妊娠18周胎儿采取活检标本和血液,受到重视。本法的缺点是胎儿镜直经过大,过多损伤腹壁和子宫壁,而且对宫腔照明不足,期待研制出胎儿镜专用新的内窥镜。
Fetal mirror is developed in recent years to obtain one of the important means of fetal intelligence, fetal intelligence can be obtained under direct vision. About 30 years ago, Westin inserted McCarthy’s wide-field cystoscopy via the cervical canal into the uterine cavity and successfully observed and photographed pregnant human fetuses in the womb under direct vision. He observed 3 cases (2 cases of general anesthesia, local anesthesia in 1 case) intrauterine fetal, but because of failure to insert the amniotic cavity, narrow field of vision, the diagnosis of small, failed to continue the test. Twenty years later, Valenti was observed using a cystoscope (about 6 mm in diameter) via the abdominal wall for observation and photographing of pregnant fetuses. The biopsy specimen and blood samples taken from fetuses at 18 weeks of gestation were valued. The disadvantage of this method is that the fetus directly through the large mirror, too much damage to the abdominal wall and uterine wall, but also inadequate illumination of the uterine cavity, looking forward to the development of fetus mirror dedicated new endoscope.
