A birth canal dilator for natural childbirth

Abstract

The invention discloses a birth canal expander for natural birth. The birth canal expander is characterized by comprising a cylindrical cage body; a nut is fixed to the centre of the rear end of the cage body; the nut is engaged with a screw to form a screw-nut vertical transmission mechanism for converting circular motion of the screw into linear motion of the lower end part of the screw; the lower end part of the screw is connected with a rod collecting disc through a connecting piece; at least four distribution holes are uniformly distributed in the periphery of the rod collecting disc; each distribution hole is fixedly connected with the upper end of an expansion rod; guide holes with corresponding number and positions to those of the distribution holes in the periphery of the rod collecting disc are formed in the circumference at the front end of the cylindrical cage body; the lower end of each expansion rod penetrates through the respective corresponding guide hole and stretches out from a horn shape below the front end of the cage body; a rod head is arranged at the front end of each expansion rod, and is used for locking when the expansion rods are gathered.

Description

technical field [0001] The invention relates to obstetrics and gynecology delivery aids, in particular to a device for non-destructive expansion of the birth canal when the puerpera has difficulties in giving birth.

Problems solved by technology

However, because the existing forceps are made of stainless steel, there is a large contrast between their own temperature and the temperature of the human body, which can easily stimulate the birth canal and cause uterine contractions.

The method of cutting the perineum will cause direct damage to the puerpera's perineum, which is prone to infection and takes a long time to recover after delivery.
