The Intelligent Insufflator is a device used for creating and maintaining pneumoperitoneum during abdominal endoscopic surgery. The insufflator can be used to infuse medical CO2 gas into the abdominal cavity, which separates the abdominal wall from intraperitoneal organs, forming a space for surgical operation and surgical field. When the desired pressure is reached, the gas intake can be automatically stopped and a volume of gas can be kept to maintain the abdominal cavity in a desired pressure inflation state.
