Combination-type intra-operative on-demand blocking branched stent-type blood vessel

A combined and intermediate stent technology is used in the field of aortic branch stents and combined intraoperative on-demand blocking branch stents, which can solve the problem that the integrated multi-branch stents are difficult to match the anatomical structure, the brachiocephalic vessels are difficult to dissociate, and the operation is difficult. Technical difficulty and other problems can reduce the operation time, improve the matching degree, and reduce blood breakage.

Embodiment Construction

[0044] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] In the present invention, the distal and proximal ends are defined according to the flow direction of the aorta, the proximal end is the side of the branch stent vessel close to the heart during the combined operation, and the distal end refers to the side of the combined operation on demand. Blocking branch stents are on the side away from the heart.

[0046] like Figure 1-2 The combined intraoperative on-demand blocking branch stent vessel provided by the present invention includes a first stent vessel 1 and a second stent vessel 2 in the direction from the distal end to the proximal end, and each segment of the stent vessel is separately provided by the main body and branch composition;

[0047] Wherein, the main body 1a of the first stent blood vessel 1 is an artificial blood vessel 5 supported by a part of metal skeleton, wherein ...

Abstract

The invention discloses a combination-type intra-operative on-demand blocking branched stent-type blood vessel. The stent-type blood vessel is used in open-type operations of replacing aorta arches and branch blood vessels thereof during the aortic dissection treatment. The combination-type intra-operative on-demand blocking branched stent-type blood vessel comprises two or three stent-type blood vessel bodies from the distal end of the aorta arch to the proximal end of the aorta arch, can be suitable for individual structures of three branch blood vessels of the aorta arch of a patient, and improves the matching degrees between the stent-type blood vessel and the three branch blood vessels of the human-body aorta arch. When the stent-type blood vessel is used, dissociative brachiocephalic blood vessels can be avoided or reduced, it is unnecessary to replace the aorta arch and branch blood vessels, anastomotic stomas are reduced, and the extracorporeal circulation time and the unilateral cerebral perfusion time are shortened, so that operative manipulation difficulties and operative wounds are reduced, the operation time is shortened, postoperative complications are reduced, and the mortality rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an aortic branch stent, in particular to a combined intraoperative on-demand blocking branch stent blood vessel. Background technique [0002] Aortic disease is a group of cardiovascular diseases that seriously threaten human health, mainly including aortic dissection and aortic aneurysm. Among them, aortic dissection is a catastrophic disease, and its incidence is dangerous. If it is not treated in time, the 24-hour mortality rate can reach 25%. Surgical treatment of Stanford type A aortic dissection is the current industry consensus. At present, the standard surgical procedure recognized by international peers for the treatment of lesions involving the aortic arch and descending aorta is Sun’s Procedure, that is, total arch replacement plus intraoperative stent implantation. Sun's surgery was founded by Professor Sun Lizhong in 2003. It is mainly suitable for patients w...
