Abstract
A device for making an amniotic cavity access through a mother and method thereof is disclosed, which includes a transvaginal fetal membrane puncture assembly configured to construct the amniotic cavity access through a natural orifice of a maternal vagina, a trans maternal abdominal wall uterine fetal member puncture assembly configured to construct the amniotic cavity access through the maternal abdominal wall and/or a belly button, and an amniotic cavity combined sheath configured to form the amniotic cavity access for placing a fetus positioning surgical robotic arm and/or surgical instruments, thereby providing a safe operation channel for the implementation of an intrauterine fetal minimally invasive surgery.
