The invention discloses a midwifery technology simulation education system based on a fetal head aspirator, and the structure of the midwifery technology simulation education system comprises a midwifery device, a vaginal orifice, a perineum part, an umbilical cord, a placenta, a pressing plate, an infant model, a connecting strip, and a uterus body model. A student stretches the obstetric forceps into the uterus body model through a vaginal opening in the perineum to conduct movable delivery on the infant model, the student controls and opens the obstetric forceps to be clamped on the head of the infant model through mutual cooperation of the finger ring and the wave forceps handle, and then the negative pressure pipe is matched with the fetal head aspirator to move. The fetal head aspirator is directly attached to the head of the baby model, contact air between the fetal head aspirator and the baby model is sucked through the negative pressure pipe, and the fetal head aspirator and the obstetric forceps are limited to the corresponding positions through the sleeve to be movably adjusted. And the obstetric forceps and the fetal head aspirator are matched with each other, so that the students in the midwifery major can personally carry out normal childbirth midwifery operation training.

The invention relates to the technical field of medical instruments, in particular to an adjustable obstetric forceps for assisting clinical production in obstetrics and gynecology department, which comprises an obstetric forceps body, the obstetric forceps body comprises two crossed forceps bodies, each forceps body is provided with a forceps head, a forceps arm and a forceps handle, each forceps head is of an arc-shaped structure, and grooves are formed in the surfaces, close to each other, of the two forceps heads. A first water bag and a second water bag are arranged in the groove, an air bag is arranged between the first water bag and the second water bag, the air bag can push the first water bag and the second water bag to stretch out of the groove to make contact with the head of the baby and push the first water bag and the second water bag to be away from each other, and the negative pressure assembly enables a cavity between the first water bag and the second water bag to form negative pressure. Therefore, the first water bag and the second water bag deform in a self-adaptive mode according to the shape of the head of the baby, overlarge local pressure caused by hard contact of traditional obstetric forceps is avoided, and the risk of injury to the head of the baby is reduced.

The invention relates to the technical field of obstetrical forceps, and particularly discloses an obstetrical forceps with a scissors function for delivery in the obstetrical department, which comprises an obstetrical forceps main body, the obstetrical forceps main body can be divided into a left blade and a right blade, and the tail part of the obstetrical forceps main body is provided with a blade handle; the clamping box is positioned at the tail part of the blade handle; the traction mechanism is positioned at one end of the clamping box, which is opposite to the obstetric forceps main body; the damping mechanism is located between the clamping box and the traction mechanism; when the device is used, a user can decide the force of pulling a tire head through the traction mechanism every time according to the force of clamping a blade handle through the clamping box, different pulling forces and distances are adjusted through the damping mechanism according to the tire heads of different sizes, and the situation that the tire heads are extruded due to the large pulling force is avoided; in the using process, in order to avoid birth canal injury, a perineum lateral cutting operation can be conducted on a puerpera through the cutting piece, and the perineum lateral cutting device is very convenient and safe to use.

This invention specifically discloses an intelligent forceps delivery system with tactile feedback and cerebral blood flow monitoring, and its control method. The intelligent forceps delivery system includes a forceps body, a flexible fiber Bragg grating sensor group, a cerebral blood flow detection sensor, a processing unit, and a host computer. The host computer is communicatively connected to the processing unit and configured to calculate and generate an adaptive safe force threshold that changes with the individual physiological state of the fetus based on the processed clamping force signal and cerebral blood flow signal, according to a preset blood flow-clamping force dynamic model. The system displays the clamping force, temperature, cerebral blood flow parameters, and the adaptive safe clamping force threshold in real time, and issues an alarm when the clamping force exceeds the threshold. This invention not only monitors clamping force and local temperature in real time but also integrates cerebral blood flow monitoring functionality. By establishing a dynamic model between clamping force and changes in cerebral blood flow, it generates an adaptive safe force threshold that adjusts in real time according to the individual physiological state of the fetus.
