Abstract

The invention relates to an artificial blood vessel perforating method. The artificial blood vessel perforating method comprises the step of positioning and cutting a reference hole and a connecting hole, and the step of positioning and cutting the reference hole and the connecting hole comprises the following steps of positioning the central point of the reference hole on the surface of an artificial blood vessel body, and cutting the surface of the artificial blood vessel body by taking the central point of the reference hole as a circle center and based on the preset radius of the reference hole to form the reference hole; and positioning the central point of the connecting hole on the surface of the artificial blood vessel body in the same circumferential direction and axial direction of the central point of the reference hole, positioning a hole opening starting point of the connecting hole on the surface of the artificial blood vessel body based on the preset radius of the connecting hole with the central point of the connecting hole as the circle center, and cutting to form the connecting hole. The position of the hole formed in an artificial blood vessel is consistent with a preset position, and the hole position is accurate; and the shape of the cut hole is regular, and the overall quality of an artificial blood vessel product is improved.

Description

technical field [0001] The invention relates to the technical field of artificial blood vessel repair, in particular to a method for opening holes of artificial blood vessels. Background technique [0002] Thoracic aortic disease is a very dangerous clinical disease, with high mortality rate and many surgery-related complications, which has always plagued the field of cardiovascular surgery. [0003] With the application of new technologies and new artificial blood vessel materials, branched artificial blood vessel products are widely used in the treatment of thoracic aortic disease. It is the key factor to determine the therapeutic effect, and the core technology that determines the performance of the branched artificial blood vessel is the hole cutting technology of the artificial blood vessel. The surface of the artificial blood vessel is usually provided with multiple connection holes for suture connection with the docked artificial blood vessel, and the multiple connec...
