Embodiment 1

[0044] see Figure 9 As shown, the patient had a lesion of the thoracic aortic aneurysm, including the ascending main segment, arch, and descending main segment. A median thoracotomy was performed on him, and the ascending aortic segment and arch were replaced with a three-branch artificial vascular prosthesis 13; one end of the artificial vascular prosthesis was sutured to the incision of the ascending aorta; the intraoperative stent prosthesis 14 was inserted into the The descending aortic incision was made and released; the overlap between the stent and the descending aortic incision was sutured to the other port of the artificial blood vessel. The three branches of the artificial blood vessel were sutured to the corresponding branch vessels (namely the brachiocephalic artery, the common tibial artery and the left subclavian artery) to complete the whole operation.

Embodiment 2

[0046] see Figure 11 , Figure 12 As shown, the patient suffered from thoracic aortic aneurysm, including the ascending aorta, arch and descending aorta, and the patient underwent a median thoracotomy. An incision was made at the ascending aorta, and the figure 2 and image 3 The stent prosthesis 14 during the operation shown is inserted toward the descending aorta, so that the exposed part of the stent during the operation is facing the three branches of the aortic arch, as shown in FIG. Figure 11 and 12 As shown in Fig. 1, the overlap between the stent and the aortic incision and the incision on the side of the ascending aorta leading to the heart were sutured to complete the operation.

Embodiment 3

[0048] see Figure 10 As shown, the patient suffered from aortic aneurysm involving the descending aorta and abdominal aorta, and the lesion involved the left subclavian artery. The patient underwent a thoracotomy at the fourth rib under the left rib, and replaced the diseased blood vessel in the descending aorta with an artificial blood vessel with a branch, which was sutured to the corresponding aortic arch incision and left subclavian artery incision respectively. Insertion through the aortic incision figure 1 Intraoperative stent as shown and release it as Figure 10 As shown; the intraoperative stent was overlapped with the abdominal aortic incision, and then sutured to the lower end of the artificial blood vessel to complete the operation.

Abstract

An artificial blood vessel, a self-elastic blood vessel scaffold and their feeder for the surgical operation of blood vessel are disclosed. Said scaffold is fixed in the artificial blood vessel. Said feeder may be thecal tube type or silk binding type. It is suitable for treating the aortic lesion.

Description

technical field [0001] The invention belongs to intravascular implants and implant instruments used in vascular surgery, in particular to a stent prosthesis in the operation and a delivery device for delivering the stent prosthesis. Background technique [0002] In traditional medical techniques, thoracic aortic aneurysm lesions, including the ascending, arch, and descending aorta, are treated with an aortic thoracotomy. During surgery, an artificial vascular prosthesis is used to replace the diseased aortic vessel. However, in the median thoracotomy, the descending aorta is blocked by the heart and is difficult to reach. Therefore, the traditional method for lesions of this section of blood vessel is to insert a general artificial blood vessel through the incision of the descending aorta (commonly known as the elephant nose). The role of this section of blood vessels is to facilitate the connection with the second surgery (usually thoracotomy from the fourth left rib). In...
