Description
Technical Field
The utility model relates to the technical field of medical treatment, especially, relate to a lower uterine segment hemostasis structure for caesarean section.
Background
Postpartum hemorrhage is a serious complication in perinatal period and is one of the main causes of death of pregnant and lying-in women in the world. With the development of the policy of the second child in China, the birth peak appears again, and the rapid increase of the proportion of the high ages of the pregnant and lying-in women is accompanied, so that the patients with the previous cesarean section history face the challenge of the second pregnancy delivery, and the number of the pregnant and lying-in women with high risk such as placenta implantation, postpartum hemorrhage and the like is increased continuously.
It is well known that caesarean section is an important means for clinical management of high risk pregnancies, and that the amount of bleeding during caesarean section is often greater than that of vaginal delivery. Postpartum hemorrhage after cesarean section, and 24 hours of accumulated hemorrhage after cesarean section can reach or exceed 1000ml, which is a serious complication in childbirth period and is the leading cause of death of pregnant and lying-in women in China.
During cesarean section, the placenta is usually attached to the front wall or the back wall of the uterine body, after the placenta is separated from the uterine wall, the blood sinuses of the uterine wall are opened in a large amount, blood loss occurs, and at the moment, the strong uterine muscle fiber contraction can rapidly close the blood sinuses, so that the aim of reducing bleeding is fulfilled. However, when the placenta is attached to the lower uterine segment or is placed in front of the placenta, the placenta is sticky or even is implanted together with the placenta, the placenta is partially or completely peeled off from the lower uterine segment, and due to the anatomical difference, the lower uterine muscle fibers shrink to close the blood sinuses, thereby having a poor hemostatic function, and are not sensitive to oxytocin, and once the lower uterine segment shrinks poorly, serious postpartum hemorrhage may be caused.
In the prior art, the bleeding treatment means for the lower section of the uterus in the cesarean section operation is very limited, and the bleeding can be stopped only by repeatedly suturing in various ways, so that a large amount of suturing and bleeding stopping operations consume manpower and material resources, prolong the operation time and often fail to achieve satisfactory effects.
