Fetal scope

The fetal scope is an amniocentroscope or an official endoscope, which is a very thin fiber optic endoscope. Fetal microscopy is a method of fetal endoscopy through the abdominal wall and uterine wall to enter the amniotic cavity, directly observe the fetal surface, and perform simple prenatal diagnosis of the fetus. It is still in the research stage. In 1954, Westin and others used a 10mm diameter hysteroscope to enter the amniotic cavity of 14-18 weeks of pregnancy through the cervical canal, and observe the situation of the fetus, placenta and umbilical cord, setting a precedent for amniotic endoscopy. Real fetal microscopy was performed in 1970 by Valenti and Scrim? Geour and other fiber optic endoscopes with a diameter of 2.7mm. They were examined before uterine incision during full-term pregnancy, and the fetal surface was observed with success. In 1974, Hobbins and Maboney reported that fetal tissue biopsy was performed under local anesthesia and fetal blood samples were obtained by umbilical vein puncture.
