Obstetric forceps capable of being attached to head of baby in self-adaptive mode

Abstract

The invention provides obstetric forceps capable of being attached to the head of a baby in a self-adaptive mode. The obstetric forceps comprises two operating arms, the two operating arms are rotationally connected through a rotating shaft, each operating arm is fixedly connected with a clamping arm, each clamping arm comprises a wrapping sleeve, each wrapping sleeve comprises a back shell and a contact membrane which are fixedly connected, and the contact membranes of the two clamping arms are oppositely arranged. A plurality of clamping mechanisms are arranged between the back shell and the contact membrane, each clamping mechanism comprises two side elastic pieces which are arranged in parallel, the side elastic pieces are bent to be arc-shaped, the protruding parts of the side elastic pieces face the contact membrane, a connecting elastic piece is fixedly connected between the two side elastic pieces, all the clamping mechanisms are sequentially nested from outside to inside, and in every two adjacent clamping mechanisms, the two side elastic pieces of one clamping mechanism located on the inner side are arranged between the two side elastic pieces of one clamping mechanism located on the outer side. The obstetric forceps can automatically adapt to the head curve of an infant in the clamping process, the contact area with the head of the infant is increased, and the situation that the infant is injured due to the fact that too large pressure is caused to the local part of the head of the infant is avoided.

Description

technical field [0001] The invention relates to the field of forceps, in particular to a forceps that can be self-adapted to a baby's head. Background technique [0002] Forceps is an instrument that can be used to assist mothers to deliver babies. Forceps midwifery is one of the important means to solve head dystocia, shorten the second stage of labor, and terminate pregnancy as soon as possible. In the prior art, the shape of the forceps is mostly fixed and cannot be adjusted according to the actual shape of the baby's head, resulting in a limited contact area with the baby's head. In order to ensure the stability of the forceps during the midwifery process, it must The baby's head is easily injured due to excessive local pressure during the midwifery process. Although some forceps can be adjusted, the adjustment method is cumbersome, wastes a lot of time, cannot complete midwifery quickly, and is detrimental to the health of the mother and the baby.
