Trainer for simulating operation of obstetric forceps, and method for operating trainer

Abstract

The invention discloses a trainer for simulating operation of obstetric forceps. The trainer is characterized in that external force acts against a fetal head through the obstetric forceps; position and attitude parameters of the obstetric forceps and the fetal head are transmitted to a computer through a three-dimensional space track locator; clamping force from the obstetric forceps and traction force which are exerted to the fetal head are transmitted to a lower computer system through a clamping force sensor and a traction force sensor respectively; data is sent to the computer by the lower computer system; position and attitude of each 3D (three-dimensional) model in a three-dimensional scene is updated by a software system which runs over a high-performance computer platform according to the collected position and attitude data, and actual operation acts in a three-dimensional scene to realize synchronous representation in real time; a fetal head motion control command is generated by the system according to stress data, and the command is sent to the lower computer system; and a fetal head drive device is controlled by the lower computer system to drive the fetal head to move.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a forceps operation simulation trainer and an operation method thereof. Background technique [0002] At present, the cesarean section rate of puerpera in my country is 50-60%, and some hospitals even go as high as 80%, which is much higher than the 15% cesarean section rate considered reasonable by the World Health Organization. The intraoperative and postoperative complications and long-term prognosis of mother and child caused by the high rate of cesarean section have attracted more and more attention. Compared with cesarean section, vaginal delivery has incomparable advantages in the short-term and long-term prognosis of mother and fetus, and forceps delivery is an important means of dystocia delivery, which can make many dystocia avoid cesarean section Switch to vaginal delivery. Forceps delivery refers to the operation of using forceps to pull the feta...

Problems solved by technology

[0003] However, due to the long-term high cesarean section rate in my country, obstetricians lack clinical experience, and young doctors have no chance to practice forceps midwifery in clinical practice. Forceps has gradually become a unique skill.

Therefore, the field of obstetrics is in urgent need of a training method that can improve obstetricians' forceps delivery. At present, medical colleges and hospitals mainly use physical maternal pelvic models to train obstetricians on the use of forceps. Accurate forceps operation technique evaluation standards and feedback channels, its teaching and training effect is not good, most obstetricians can only learn the practical skills in the delivery room, and a doctor who can skillfully use forceps needs long-term The practice of midwifery, which increases the risk of harming the mother and fetus to a certain extent
