An intelligent monitoring system for evaluating the safety of cesarean section surgery, characterized in that: include: A surgical risk value assessment unit, used to determine the risk value corresponding to the patient's cesarean section surgery based on the acquired surgical indications of the patient; Surgical indications are used to characterize the physiological status of patients who are not suitable for vaginal delivery; The preoperative balloon placement unit is used to monitor the image data below the opening of the patient's renal artery using a digital angiography machine and a color Doppler ultrasound imaging device before a cesarean section when the risk value is greater than a preset risk value threshold; determine the target position for placing the balloon and balloon blocking parameters according to the monitored image data; and place the balloon into the patient's abdominal aorta and fix it according to the target position; The intraoperative intelligent monitoring unit is used to fill the balloon according to the required amount of saline to fill the balloon and the abdominal aorta balloon occlusion time during the cesarean section operation, at the moment of fetal delivery or when the patient enters a state of heavy bleeding, so as to block the blood flow of the lower abdominal aorta; while starting to fill the balloon, the patient's lower limb pulse oxygen is monitored to evaluate the ischemic condition of the pelvic cavity and lower limbs; The surgical suturing unit is used to remove the balloon after the cesarean section is completed and suture the surgical site using a variety of suturing techniques; Before the cesarean section, the bifurcation positions of the patient's bilateral renal arteries and abdominal aorta are measured and marked in vitro using a digital angiography machine and a color Doppler ultrasound imaging device; the diameter of the patient's abdominal aorta, the state of the blood vessels around the bifurcation position, the state of the muscles around the bifurcation position, the state of the bones around the bifurcation position, and the state of the nerves around the bifurcation position are determined using the image data monitored by the digital angiography machine and the color Doppler ultrasound imaging device; the target position for balloon placement, the amount of saline required to fill the balloon, the abdominal aorta balloon occlusion time, and the blood flow recovery time are determined based on the blood vessel state, the muscle state, the bone state, and the nerve state; Among them, a first 3D reference plane is established according to the neural state and the skeletal state; a first spatial attention matrix is ​​generated based on the neural state and the skeletal state through the position of the bifurcation position relative to the first 3D reference plane; a second 3D reference plane is established according to the patient's abdominal aorta diameter, the vascular state and the muscle state; a second spatial attention matrix is ​​generated based on the patient's abdominal aorta diameter, the vascular state and the muscle state through the position of the bifurcation position relative to the second 3D reference plane; the second spatial attention matrix is ​​subjected to linear processing, nonlinear processing and parameter loss processing to obtain a second graph space feature matrix; the target position for placing the balloon and the amount of saline required to fill the balloon are determined based on the second graph space feature matrix; according to the position of the bifurcation position relative to the first 3D reference plane and the position of the bifurcation position relative to the second 3D reference plane, the first spatial attention matrix and the second spatial attention matrix are weightedly fused to obtain a fused spatial attention matrix; the fused spatial attention matrix is ​​used as a reference, combined with the analysis results of ultrasound and interventional doctors, to determine the abdominal aorta balloon occlusion time and blood flow recovery time.

2. The intelligent monitoring system for evaluating the safety of cesarean section surgery according to claim 1, characterized in that: The intelligent monitoring system for evaluating the safety of cesarean section surgery also includes a balloon parameter real-time adjustment unit for: After starting to detect and monitor the patient's lower limb pulse oxygen, the patient's pelvic and lower limb ischemia status is evaluated based on the monitored lower limb pulse oxygen to obtain real-time ischemia evaluation results; The amount of saline required to fill the balloon, the abdominal aorta balloon occlusion time and the time to restore blood flow are adjusted in real time based on the patient's real-time ischemia assessment results.

3. The intelligent monitoring system for evaluating the safety of cesarean section surgery according to claim 1, characterized in that: Surgical indications include one or more of the following: fetal distress, cephalopelvic disproportion, uterine scar, malposition of the fetus, placenta previa and vasa previa, and multiple pregnancy; various suturing techniques include one or more of the following techniques: B-Lynch suture technique, patch suture technique, and cervical lifting suture technique.
