Problems solved by technology

[0006] (1) Caesarean section extracts part of the amniotic fluid and removes the fetus, which severely traumatizes the uterus and easily induces maternal uterine contraction
[0007] (2) Taking out the fetus by cesarean section will inevitably damage the placenta, resulting in damage to the placenta and easy induction of placental abruption
[0008] (3) The fetus completely or partially leaves the mother's uterus, causing the fetus to escape from the uterus and amniotic fluid safety protection, resulting in potential damage to the fetus

Abstract

The invention relates to a device for making an abdominal, uterus and amniotic cavity channel, wherein the device is used for manufacturing a channel for performing fetal intrauterine surgical treatment through a navel or an abdominal wall, and comprises a puncture device and an abdominal wall, uterus wall and amniotic cavity combined sheath, wherein the front end of the puncture device comprises self-tapping threads for precise puncture of foetal membranes; and the abdominal wall, uterine wall and amniotic cavity combined sheath is used for constructing a channel penetrating through the abdominal wall, the uterine wall and the amniotic cavity and meanwhile establishing rigid and stable connection with a support beside an operating table.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a device for making an abdominal uterine amniotic cavity channel and its usage. Background technique [0002] The incidence of fetal birth defects is 4%-6%. Birth defects have become an important public health and social problem in the world. Compared with deformity correction after birth, intrauterine surgical correction of congenital malformations has many advantages, including maternal placenta providing safe support, avoiding intrauterine growth delay or death, scarring in the surgical area is not obvious, and reducing family psychological and cost burdens. [0003] Fetoscopy is only suitable for intrauterine treatment of a few birth defects, such as twin-to-twin transfusion syndrome, drainage, and intrauterine blood transfusion. Slightly complicated congenital defects, such as tumors, diaphragmatic hernia, myelomeningocele, exposed viscera, cleft lip and palate, usually r...
