The utility model provides a branch blocks formula support type artificial blood vessel system as required in art, branch blocks formula support type artificial blood vessel system as required in art includes that main part artificial blood vessel, branch's tectorial membrane support, branch block device and release, the branch blocks unit bit in near junction or the branch tectorial membrane support intracavity of main part artificial blood vessel with branch's tectorial membrane support, the branch blocks the device and is separable the connection within a definite time with main part artificial blood vessel or branch's tectorial membrane support, can realize main artery and the control of the intervascular intercommunication of branch's blood. Through using the utility model discloses a branch blocks formula support type artificial blood vessel system as required in art can control as required in the operation that main artery and aortic arch top set blood are intervascular to be blocked and feed through, reduces or avoids dissociating, blocking or coincide etc. Bow top set is hematal, simplifies operation technique greatly, reduces the damage to blood vessel and surrounding tissue.
