Background
When the heart is subjected to open-heart surgery, the blood supply of the heart is interrupted, if the heart is not protected, and the heart is subjected to ischemia at normal temperature for 15 minutes to cause irreversible injury, so that the heart muscle protection is needed in the operation. The application of the cardioplegia stopping liquid perfusion tube is inevitable in the operation, and mainly plays the roles of perfusion of cardioplegia stopping liquid and intracardiac exhaust after the aorta is opened. The cardioplegia fluid perfusion tube is generally inserted into the highest point of the ascending aorta, and after the cardioplegia fluid perfusion tube is pulled out after extracorporeal circulation is finished, the outer membrane is generally tied by a purse wire sewed by the outer membrane to shrink the outer membrane so as to close the injury of the puncture point of the ascending aorta. With the development of aging population, the age of a patient gradually increases, the quality of the aortic wall is poor, and aortic adventitia injury and ascending aortic intima and media injury can not be closed easily when a single adventitia purse string is knotted, so that aortic hematoma or iatrogenic dissections occur, serious intraoperative complications occur, and the life of the patient is endangered. Meanwhile, all the existing puncture needle type cardioplegia perfusion tubes exceed the intima for a certain distance, so that the air in the ascending aorta cannot be fully discharged in the operation. There was a patent application for cardioplegia perfusion tube 201420097100.6 in 2014, but this patent application still fails to address the two problems of possible injury to the ascending aorta and insufficient ventilation. Reducing the clinical practicability.
