Instrument suite for making vagina, cervix and amniotic cavity channel and using method of instrument suite

Abstract

An instrument suite for making a vagina, cervix and amniotic cavity channel is used for making a channel for performing fetal intrauterine surgical treatment through a cervix natural cavity and comprises a vaginal speculum, a cervix dilator, a fetal membrane puncture outfit and a vagina, cervix and amniotic cavity combined sheath, wherein the vaginal speculum is provided with a light source for cervical dilation under direct vision; and the cervix dilator is provided with an air bag module used for improving the cervix dilation efficiency, the front end of the fetal membrane puncture outfit is provided with self-tapping threads used for accurately controlling fetal membrane puncture, and the vagina, cervix and amniotic cavity combined sheath is provided with a one-way valve and a fastening assembly used for constructing a channel penetrating through the vagina, the cervix and the amniotic cavity and meanwhile preventing amniotic fluid from flowing out, and rigid stable connection with an operating table bracket is established.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an instrument kit for making vaginal, cervical, and amniotic cavity passages 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 fetal intrauterine growth delay or death, scarring in the surgical area is not obvious, and reducing family psychological and financial 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 li...

AI Technical Summary

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

[0009] (4) Although laparoscopic surgery can reduce abdominal and uterine trauma, the fetus swims in the uterus, and it is difficult to reveal defects or deformities, which greatly increases the difficulty of surgery
