Abstract
The utility model relates to the technical field of the medical appliance, in particular to an endovascular graft which has a branch and is applicable to aortic arch part with pathological changes. The utility model is composed of a wire bracket (1) and a tubular fiber fabric (2) fixed in the bracket and is divided into a main body part (3) and a branch (4); wherein, the bracket (1) is structured as that a hyperelastic thin alloy wire is coiled into a plurality of bracket circles after being continuously folded in Z shape and is arranged like a tube; the first bracket circle (5) close to the center of the main body part is exposed with no fabric. The relative positions of the endovascular graft are provided with metal markers (6). The utility model is simple for operation, high in operation success rate, little in wound and low in complication rate when being implanted.
Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of ramose endovascular graft of being with of aortic arch portion that is applicable to.
Background technology
Along with growth in the living standard and inspection development of technology, the angiopathy of aortic arch portion presents ascendant trend, and the disease of involving aortic arch portion three big branch vessel (innominate artery, left common carotid artery, left subclavian artery) comprises aortic arch portion true aneurysm, Stanford A type dissection of aorta or the like.Often because factor such as aortosclerosis, hypertension and vasodilation takes place gradually, after arterial wall is expanded to a certain degree, can not bear the impact of blood stream pressure and break suddenly behind this type of disease incidence, thereby cause patient's sudden death.
In recent years, adopt endovascular graft minimally-invasive treatment arotic disease to obtain develop rapidly, reduced the complication rate and the mortality rate of operation.The blood vessel inner cavity insulation therapeutic appliance that this operation is used is called barrier systems in endovascular graft or the lumen of vessels, form by wire rack mount and the tubular fiber fabric that is fixed in the support, support is provided with the metal marker thing, so that under the X line, it is accurately pushed to diseased region with carrier, its medium-height trestle surrounds into some bracket loops after folding and is arranged in tubulose and forms by the thin alloy silk of super bullet is continuously Z-shaped, be used for fabric being strutted and being fixed in diseased region, fabric is equivalent to artificial blood vessel, is attached at diseased region and (sees CN2427227Y " a kind of novel vascular inner cavity insulation system " for details with lesion vessels section and blood flow are isolated; CN2427172Y " barrier systems in a kind of novel descending aorta lumen of vessels ").Shape and ramose difference thereof according to the diseased region blood vessel can be made into different endovascular grafts.With carrier endovascular graft is delivered to the vascular lesion position and discharge, the swollen voluntarily blood vessel wall of being close to diseased region of opening of support so promptly can be avoided aneurysm to break under blood flow impacts, thereby reach the minimally-invasive treatment purpose.
The bifurcated artery that aorta sends is numerous, and with the blood of supply corresponding organs, wherein the innominate artery, left common carotid artery and the left subclavian artery that send of aortic arch portion is supply head and upper limb blood, and its importance is apparent.At present adopt of aortic arch portion disease opened breast extracorporeal circulation aorta replacement operation more, operation wound is big, also have in recent years and use endovascular graft, but this graft is not with branch, so the branch vessel of aortic arch portion must be gone shunt, promptly need to rebuild bow part branch vessel, operation wound is big like this, post-operative complication rate and mortality rate height bring huge misery and financial burden to the patient.
Summary of the invention
The purpose of this utility model provides a kind of ramose endovascular graft of being with of aortic arch portion that is applicable to.When this kind endovascular graft was placed aortic arch portion, its branch inserted in innominate artery or left common carotid artery or the left subclavian artery, can guarantee head and the confession of upper limb blood, and helped the fixing of endovascular graft.
This utility model is made up of wire rack mount and the tubular fiber fabric that is lining in the support, be divided into main part and branch's two parts, support continuously Z-shapedly surrounds into some bracket loops after folding and is arranged in tubulose and forms by the thin alloy silk of super bullet is capable, be used for fabric being strutted and being fixed in diseased region, fabric is equivalent to artificial blood vessel, is attached at diseased region lesion vessels section and blood flow are completely cut off.Main part proximal part first lap does not cover fabric for exposed bracket loop, it is characterized in that according to the hemangioma present position, corresponding site at innominate artery or left common carotid artery or left subclavian artery is provided with branch, and be provided with the metal marker thing in the region of interest of endovascular graft, as being provided with the metal marker thing at tubular fiber fabric periphery and main part and ramose boundary, so as when to insert under the X line according to its accurately location of developing.The length of main part is different because of the difference of the residing position of each branch and each branch's caliber size.To branch into the boundary, be with the ramose graft of innominate artery, its nearly heart section (not containing exposed bracket loop) is long than other two kinds of grafts, is generally 30-110mm, and heart section far away is shorter, is generally 10-15mm; The nearly heart section of the band ramose graft of left common carotid artery is suitable with heart segment length far away, is 10-15mm; And the ramose graft of band left subclavian artery, its nearly heart section is generally 10-15mm, and heart Duan Ze far away is longer, is generally 30-150mm.This utility model can be made different specifications and models as required.
During use, according to the difference of aortic arch portion diseased region, select the graft of corresponding specifications and models, insert carrier after folding, under the X line, import aortic arch portion relevant position along blood vessel routinely, during release branch is inserted corresponding branch vessel and get final product by import system.
Easy to operate when this utility model is implanted, the success rate of operation height, wound is little.
