[0019] The auxiliary device for the heart aorta replacement artificial blood vessel surgery has the features that the bag body is a water bag or an air bag.

[0020] As Figures 1-5As shown, an auxiliary device for aortic replacement surgery includes a sac 1 that can expand and extend into the aorta to block blood flow. The sac 1 has a sac channel 2 for blood to pass through. A drainage tube 3 is connected to the upper end of the sac 1. A drainage tube cavity 4 is provided at the connection end between the drainage tube 3 and the sac 1. A drainage tube through hole 5 is provided on the outer side of the drainage tube 3 for guiding the blood leakage between the sac 1 and the aorta into the drainage tube cavity 4. The drainage tube 3 is provided with a drainage tube channel 6 that communicates with the sac channel 2 for sending blood from the aorta into an extracorporeal circulation device, an injection channel 7 for injecting or drawing liquid or gas into the sac 1 to expand and contract the sac, and a blood extraction channel 8 for drawing out the blood leakage from the drainage tube cavity 4.

[0021] When using it, it will be as follows Figure 1 The sac 1, in its contracted state, is inserted into the aorta of the heart. Water is injected into the sac 1 through the injection channel 7, causing it to expand and block blood flow. At this time, blood is sequentially transported to the extracorporeal blood circulation device through the sac channel 2 and the drainage tube channel 6. During the suturing of the aorta and the artificial blood vessel, blood seeping from between the sac 1 and the aorta enters the drainage tube lumen 4 through the drainage tube through hole 5. The negative pressure blood aspiration device operates to extract the seepage blood in the drainage tube lumen 4 through the seepage extraction channel 8, thus solving the problem of seepage blood obstructing the suturing view. After suturing, the water in the sac 1 is extracted through the injection channel 7 to cause the sac 1 to contract. After stopping the extracorporeal blood circulation, the sac 1 can be removed.
