Description

A new type of forceps

technical field

The utility model belongs to the technical field of medical instruments, in particular to a new type of forceps.

Background technique

At present, obstetricians and gynecologists can perform vaginal delivery when the second stage of labor is prolonged, the second stage of labor is suspected, or the second stage of labor needs to be shortened due to maternal reasons. To achieve the purpose of mother and child peace. At present, the most commonly used vaginal midwifery in the obstetrics and gynecology department of the hospital is to use forceps to directly pull the fetal skull, or to pull the fetal scalp through a negative pressure suction device. Use these appliances to help mothers in childbirth, thereby assisting in the delivery of the fetus. When the fetal head suction device is used for midwifery, since the suction cup is set on the fetal head and has a certain negative pressure, it is easy to cause fetal intracranial hemorrhage or head deformation during midwifery, which seriously affects the fetal health. Safety.

Forceps are the most commonly used midwifery instruments in the obstetrics and gynecology department of hospitals. Forceps are used to help mothers in childbirth. As long as the doctor's technique is proper and the forceps are placed in the right position, the damage to the fetus is small. When using forceps for midwifery, because the existing forceps are generally placed on the lower edge of the auricle on both sides of the fetal head, the fetus is delivered through the handle of the forceps, which is not only inconvenient to use, but also inconvenient to use. And because the head of the fetus is big or small, relying on the experience of the medical staff to hold the forceps is easy to cause harm to the mother and baby, and when the maternal force is insufficient and the fetus is difficult to stretch, the fetus cannot be successfully delivered through the forceps. This not only brings difficulties to doctors, but also aggravates the pain of mothers.
