When ascending aorta replacement, full arch replacement and trunk stent implantation operations are performed, double arteries of the right axillary artery and the femoral artery of a patient are intubated through a second blood transfusion pipe 72 and a third blood transfusion pipe 73, and an extracorporeal circulation is established by intubatton of the right atrium through a first blood transfusion pipe 71 and cooperation with an extracorporeal circulation machine 6; implanting a trunk support to a thoracic descending aorta 9 under the conditions of deep low temperature, circulation stopping and low flow unilateral cerebral perfusion, cutting off a pre-connected communicating pipe 3 through a blood blocking piece 4 after the trunk support is released, and restoring distal blood supply through femoral artery intubation so as to finish the deep low temperature circulation stopping and circulation, and anastomosing the near end of the trunk support with the far end of a main blood vessel 8 of a four-branch blood vessel under the condition of restoring the distal blood supply; under the condition that the anastomosis is nearly finished, the femoral artery perfusion is suspended, the connection between the communicating pipe 3 and the coated pipe 2 is released to separate the communicating pipe 3 and the coated pipe, the remaining anastomosis operation is quickly finished, the near end of the main four-branch blood vessel 8 is blocked after the operation is finished, and the far end perfusion is recovered; therefore, through the trunk support assembly, the blood blocking structure can be applied to the anastomosis process of the trunk support and the far end of the main vessel 8 of the four-branch vessel, thereby effectively shortening the time of deep low temperature and stopping circulation and improving the curative effect of the operation.
According to general statistics, the operation of the trunk support implanting system is shortened from 20-30 minutes of the prior operation to 3-5 minutes in the deep hypothermia and circulatory arrest time, which is of great significance to cardiovascular operations with minutes and seconds.
Finally, it is stated that the specific individual example is used herein to explain the principle and the implementation of the present invention, and the explanation of the above embodiment is only used to help understand the core idea of the present invention, without departing from the principle of the present invention, it is also possible to make the present invention undergo several improvements and modifications, and these improvements and modifications also fall into the protection scope of the present invention.
