Abstract

The invention discloses a fetal reduction device. The device comprises a handle and a strangling assembly disposed at one end of the handle. The strangling assembly is retractably disposed in a firstcontaining cavity in the handle and comprises a first strangling blade and a second strangling blade, and the first strangling blade and the second strangling blade can be retracted and expanded. Thestrangling assembly is retracted in the first containing cavity of the handle before the fetal reducing device is positioned to prevent the strangling assembly from damaging the cervix when the fetalreducing device passes through the cervix, and the first strangling blade and the second strangling blade are expanded when the strangling blades puncture a fetal heart, so that the destructive capability of the strangling assembly is enhanced to ensure that the fetal heart of a fetus subjected to fetal reduction is stopped; moreover, a syringe is arranged in the handle, an injection needle is poked into the fetal heart, and a propeller is pushed for injecting potassium chloride to make the fetal heart stop immediately, so that the two operating means are conveniently switched.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to a tire reducing device. Background technique

[0002] With the application of assisted reproductive technologies such as ovulation induction technology and artificial insemination, on the one hand, it has brought hope for infertility patients to have children, but on the other hand, multiple pregnancies have also increased. Because multiple pregnancy is prone to miscarriage, premature birth, low birth weight, etc., it is difficult to guarantee the survival of the fetus, and it increases the complications of pregnant women, which seriously affects the health of pregnant women and fetuses and even endangers their lives. In the past, multiple pregnancy was generally treated with abortion or left unchecked, but in recent years, the use of fetal reduction surgery can safely and effectively control the number of fetuses delivered, improve the survival rate of fetuses, and greatly reduc...
