Description

Novel obstetric forceps

Technical Field

The utility model belongs to the technical field of medical instrument, in particular to novel obstetric forceps.

Background

At present, when a gynecologist carries out natural delivery for a lying-in woman, when the second labor is prolonged and suspicious fetal distress occurs to the lying-in woman or the second labor needs to be shortened due to the lying-in woman, the gynecologist can carry out vaginal delivery assistance to help the lying-in woman to finish delivery as soon as possible so as to achieve the purpose of ensuring the mother and son to be safe. The most common vaginal delivery aid in obstetrics and gynecology department in hospitals at present is completed by directly drawing fetal skull by using obstetric forceps or drawing fetal scalp by using a negative pressure suction apparatus. These devices help the parturient to give birth and thus assist in the delivery of the fetus. When the fetal head aspirator is used for midwifery, the sucker is arranged at the head of a fetus and has certain negative pressure, so that the conditions of intracranial hemorrhage, head deformation and the like of the fetus are easily caused during the midwifery, and the safety of the fetus is seriously influenced.

The obstetric forceps are the most common delivery aid in obstetrics and gynecology department in hospitals at present, and the obstetric forceps are used for helping a parturient to deliver, so long as a doctor has proper manipulation and places the obstetric forceps properly, the obstetric forceps have small damage to a fetus. When carrying out the practise midwifery through obstetric forceps, because current obstetric forceps place the clamp body at the auricle lower edge of foetus head both sides when using generally, detain foetus head and give birth to the foetus through the pincers handle, so not only inconvenient to use, and because foetus's head has big or small, control obstetric forceps by medical personnel's experience, cause the injury for the mother and infant easily, and when meetting that lying-in woman's power of labor is not enough and foetus stretches up the difficulty, can't pass through obstetric forceps smoothly and give birth to the foetus, this has not only brought the difficulty for the doctor, the misery of lying-in woman has also been aggravated simultaneously.

SUMMERY OF THE UTILITY MODEL
