The utility model relates to technologies for medical instruments, and is an integrated fenestration endovascular graft, which comprises a metal wire bracket (1) and a tubular fabric (2) fixed inside the bracket, wherein the utility model contains a straight tube section (3) and a fork section (4), characterized in that: a window (6) sized corresponding to pore diameter of the blood vessel is opened on the tubular fabric at a position corresponding to the renal artery; other windows sized corresponding to pore diameter of the blood vessel may also be opened on the tubular fabric at corresponding positions where other branch vessels are distributed at the position of the vascular tumor; a metal tag (5) is provided on periphery of each window; the fork section (4) contains branches underneath the straight tube section, and comprises a long branch and a short branch, wherein the short branch can be used for socket joint with straight tube endovascular grafts (7) of corresponding diameter and desired length. By changing existing split-type fenestration endovascular graft into an integrated type, the utility model ensures more convenient implantation works, with high surgical success rate, minimal invasion and low complication rate.

Description

One-piece type fenestration endovascular graft
Technical field
This utility model relates to technical field of medical instruments, is one-piece type fenestration graft in a kind of novel lumen of vessels.
Background technology
Aortic aneurysm is because factor such as aortosclerosis and office's section property blood vessel wall cryptomere expansion of taking place gradually, can not bear the impact of blood flow and break suddenly after arterial wall is expanded to a certain degree, thereby cause patient's sudden death.In recent years, adopt endovascular graft to carry out the minimally-invasive treatment aortic aneurysm and obtain develop rapidly.Endovascular graft also claims barrier systems in 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 accurately is pushed to diseased region with carrier, its medium-height trestle 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 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 according to the diseased region blood vessel can be made into different endovascular grafts.For abdominal aortic aneurysm, be that the boundary is divided into abdominal aortic aneurysm and infrarenal abdominal aorta tumor on the kidney with the renal artery.Distance between the near-end of renal artery and infrarenal abdominal aorta tumor (being the upper limb of tumor body) is called the tumor neck, be shorter than abdominal aortic aneurysm on the infrarenal abdominal aorta tumor of 15mm or the kidney for the tumor neck, for preventing that renal artery blood flow is obstructed, existing separation type fenestration endovascular graft comes out, as the product of U.S. COOK company.This separation type fenestration endovascular graft is divided into straight tubular fenestration endovascular graft and traditional Y-shaped endovascular graft two parts.Do not cover fabric in the first lap bracket loop of straight tubular fenestration endovascular graft, the angle folding of its lower edge and fabric suturing with thread management, characteristics be on the fabric at ventral aorta branch vessel position, open one with the window of blood vessel respective aperture, as respectively opening a window,, it flows into renal artery by this window from aorta swimmingly so that being implanted back blood at left and right sides renal artery corresponding site.Traditional Y-shaped endovascular graft divides vertical tube part and furcation two parts, the similar of vertical tube part and above-mentioned straight tubular fenestration endovascular graft, and the first lap bracket loop is exposed not to cover fabric, but does not window on the vertical tube part fabric; Furcation is the branch below the vertical tube part, and a long branch and a short branch are arranged, as required can be in short branch the straight tubular endovascular graft of socket respective diameters and Len req.During use, earlier straight tubular fenestration endovascular graft is implanted corresponding site with carrier from femoral artery (or iliac artery), each window is aimed at the respective branch blood vessel, the reuse carrier is implanted traditional branch type endovascular graft from femoral artery (or iliac artery), the upper end of vertical tube part is socketed on the straight tubular fenestration endovascular graft lower end of having implanted, the overlapping to some extent in case hemostasis liquid seepage of the tubular fiber fabric portions that had both made both prevents to be inserted in too dark fabric again the former window is blocked.This separation type fenestration endovascular graft can be isolated with lesion vessels section and blood flow effectively, but have following defective: it is big 1, to implant wound at twice, complex operation; 2, the degree of depth is difficult when the latter and the former socket grasps, and too simple and easyly comes off or causes seepage, might the former window be blocked fabric too deeply, and being in course of adjustment also to make the former be shifted, and causes the window obstruction, causes catastrophic effect.
Summary of the invention
The purpose of this utility model provides the one-piece type fenestration endovascular graft that a kind of wound is little, easy to operate, success rate of operation is high.
This utility model is made up of wire rack mount and the tubular fiber fabric that is fixed in the support, divide vertical tube part and furcation two parts, vertical tube part is a main body, structure is the same with the straight tubular fenestration endovascular graft of above-mentioned separation type fenestration endovascular graft, do not cover fabric in the first lap bracket loop of top, vertical tube part has the window with this blood vessel respective aperture on the fabric of ventral aorta branch vessel corresponding site, as respectively opening a window at left and right sides renal artery corresponding site, the window limit is provided with special metal marker thing, for different branch vessel windows, set metal marker thing quantity or position be difference to some extent, so as when to implant under the X line according to its accurately location of developing; Furcation is the branch below the vertical tube part, and a long branch and a short branch are arranged, and can be inserted in the straight tubular endovascular graft of respective diameters and length in short branch.This utility model is equivalent to the straight tubular of above-mentioned separation type fenestration endovascular graft and Y-shaped two parts endovascular graft are integrated.But change into just one-piece type, just can when implanting, make easy and simple to handle, the success rate of operation height, wound is little, significantly reduces contingent complication.
