Abstract:

Operative vaginal birth refers to the use of vaginal midwifery instruments to traction the fetal head in the second stage of labor in order to accelerate or realize fetal vaginal delivery. The commonly used vaginal midwifery instruments are forceps and vacuum. But in clinical work, the application is limited by the possible damage caused by the instrument and the operator′s skills. In 2009, the World Health Organization (WHO) approved the testing of a new midwifery device (Odon Device) on humans. The purpose of Odon Device is to place a cuff over the widest diameter of the fetal head, and then use traction to assist the delivery of the fetus. Compared with common midwifery instruments, Odon Device has the features of low cost, high clinical safety and effectiveness, and operators can acquire operational skills with less training. With the encouragement of the WHO, six studies to test the device have been completed: four preclinical studies and two clinical studies in uncomplicated vaginal delivery. This article will comprehensively discuss the development history, working principle and obstetrical mechanism of Odon Device, as well as the results of preclinical and clinical studies, in order to provide reference for the operative vaginal birth.
