Description

An intelligent hemostatic device for bleeding during cesarean section

technical field

The invention relates to an intelligent hemostasis device for bleeding during cesarean section, belonging to the technical field of surgical instruments.

Background technique

The cesarean section rate in my country is increasing year by year. Data shows that the cesarean section rate in my country is as high as 46%. Postpartum uterine atony is very common. Therefore, postpartum hemorrhage is a common complication of cesarean section. , in severe cases may endanger the safety of maternal life. Postpartum hemorrhage is one of the four major causes of maternal death, so rapid and efficient postpartum hemostasis is a key measure for clinical treatment.

When puerperae suffer from postpartum hemorrhage due to uterine atony, when traditional conservative treatments such as hemostasis, blood transfusion, and prevention of hemorrhagic shock are ineffective, surgical hemostasis is often chosen. Surgical hemostasis mainly includes hysterectomy, uterine sling suture, uterine artery ligation, bilateral uterine artery embolization and uterine packing balloon catheter. Hysterectomy has a good effect on the treatment of postpartum hemorrhage, but it will cause the loss of reproductive organs and fertility of patients, which will seriously affect the mental health and quality of life of patients. Uterine sling suture mainly uses sutures to compress the atony uterus, so that the patient's uterus is maintained in a state of contraction, and then the patient's uterine arteries and veins are compressed to reduce uterine bleeding and achieve hemostasis. Effect, but this method It belongs to invasive surgery, and the problem of suture slippage or uterine avascular necrosis is easy to occur after treatment. The surgical operation of uterine artery ligation is relatively complicated, and the hemostasis effect is not good. Studies have found that the effective rate of uterine artery ligation in the treatment of postpartum hemorrhage is only 42%, and the trauma is relatively large, and the prognosis is often poor. Bilateral uterine artery embolization is to identify the bleeding site and scope of bleeding under the guidance of DSA, and then use an embolic agent to block the uterine artery. Some patients have symptoms such as hip pain and fever. Although the uterine tamponade balloon catheter has a certain curative effect in the treatment of postpartum hemorrhage, because its force is mainly on the surface of the uterine cavity, the hemostasis effect is not good, and there is a certain rate of postpartum hysterectomy and recurrence of postpartum hemorrhage, and patient satisfaction is not very high. high.

To sum up, facing the problem of bleeding after caesarean section, the existing treatment methods still have problems such as large trauma, obvious side effects, and poor effect.
