The utility model has the advantages of simple structure and convenient operation, and can effectively isolate the diseased blood vessel segment of the abdominal aorta and (or) external iliac artery and (or) internal iliac artery from blood flow, and can ensure the smooth flow of internal iliac artery blood flow, eliminating the need for pelvic The hidden danger of ischemia has a high success rate of operation.
Description
Technical field
This utility model relates to technical field of medical instruments, is implant system in the inside and outside lumen of artery of a kind of one-piece type ventral aorta-ilium.
Background technology
Abdominal aortic aneurysm is because factor such as arteriosclerosis 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, endovascular graft is applied to treat aortic aneurysm in the Wicresoft field more and more widely.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 lesion vessels section and blood flow are completely cut off.Shape and ramose difference according to the diseased region blood vessel can be made into different endovascular grafts.
Have ventral aorta-external iliac artery endovascular graft both at home and abroad, it is roughly herringbone, the ventral aorta part is thicker, be vertical tube part, do not cover fabric in the Z-shaped bracket loop of upper end first lap, first lap angle folding lower edge and fabric are fixed with line or other modes, and maskable ventral aorta lesion vessels section is isolated with lesion vessels section and blood flow; Its lower end extends to furcation, and two thinner branches are arranged, a long branch and a short branch, and long branch location, ilium inside and outside tremulous pulse total corresponding to a side ilium, long branch is used for that a side ilium is always reached external iliac artery lesion vessels section and blood flow is isolated; Short branch location is corresponding to the opposite side common iliac artery.If the bilateral external iliac artery all has pathological changes, then can in short branch, be inserted in adding of respective diameters and length to draw money on credit, add and draw money on credit to straight tubular endovascular graft, do not cover fabric in the Z-shaped bracket loop of upper end first lap yet.
This endovascular graft can be isolated with lesion vessels section and blood flow effectively, but owing to there is not internal iliac artery branch, if pathological changes is involved the inside and outside tremulous pulse of ilium, internal iliac artery keeps external iliac artery so can only be sacrificed, be first thromboembolism or ligation internal iliac artery, insert graft again, will cause internal iliac artery blood like this for being obstructed, if bilateral internal iliac is all blocked, will causes the pelvic cavity ischemia and lead to complications.
The inside and outside arteries intracavity implant of a kind of separation type ventral aorta-ilium is abroad arranged, form by above-mentioned ventral aorta-external iliac artery graft and internal iliac artery branch, the graft main body is above-mentioned ventral aorta-external iliac artery graft, but a window is established in the position that is equivalent to the internal iliac artery opening part in its long branch, internal iliac artery branches into the little endovascular graft of tubular always, the ramose internal diameter coupling of external diameter and internal iliac artery, elder generation's implantation graft main body makes the window of growing in the branch on the main body place the internal iliac artery opening part during use, by this window internal iliac artery branch is implanted internal iliac artery again, discharge.Though the inside and outside arteries intracavity implant of this separation type ventral aorta-ilium has internal iliac artery branch, the degree of depth is difficult during socket grasps, and causes easily to come off or seepage.
Summary of the invention
The purpose of this utility model provide a kind of can guarantee the internal iliac artery blood flow unimpeded, again can not occur coming off or the inside and outside lumen of artery of ventral aorta-ilium of internal hemorrhage due to trauma in implant system.
This utility model is made up of wire rack mount and the tubular fiber fabric that is fixed in the support.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, is used for fabric being strutted and being fixed in diseased region, and fabric is equivalent to artificial blood vessel, is attached at diseased region lesion vessels section and blood flow are completely cut off.This utility model graft divides vertical tube part and furcation two parts, vertical tube part is the ventral aorta part, thicker, do not cover fabric in the Z-shaped bracket loop of upper end first lap, the lower edge of first lap angle folding and fabric are fixed with line or other modes, vertical tube part maskable ventral aorta lesion vessels section, lesion vessels section and blood flow is isolated; It is two thinner branches that bifurcated is extended in its lower end, is furcation, and a long branch and a short branch are arranged, and the position is total corresponding to the bilateral ilium, external iliac artery.Short branch can be provided with its diameter and length adding of being complementary and draw money on credit; The region of interest of wire rack mount is provided with the metal marker thing, establishes the metal marker thing as the boundary of vertical tube part and furcation, so that with carrier it accurately is pushed to diseased region under the X line.It is characterized in that in the long branch of furcation, being provided with internal iliac artery branch, also can establish internal iliac artery branch on drawing money on credit in short ramose adding.Because the internal iliac artery branch and the external iliac artery branch of this utility model graft are connected as a single entity, operate easily when therefore implanting, and can not come off or the seepage phenomenon after implanting.
This utility model is simple in structure, and is easy to operate, can be effectively that the lesion vessels section and the blood flow of tremulous pulse inside and outside ventral aorta common iliac artery, the ilium is isolated, and can guarantee that the internal iliac artery blood flow is unimpeded, eliminated the hidden danger of pelvic cavity ischemia, the success rate of operation height.
