Abstract
The utility model discloses a new style aorta membrane-covered support which is composed of a tubular metal support whose shape is matched with the shape of the blood vessel of the aorta and an artificial blood vessel which is covered on the surface of the tubular metal support, wherein, the metal support is in a Z shape or in a diamond pattern; the aorta membrane-covered support is in the tapering and bending structure. The utility model has simple and convenient operation, small trauma, and difficult displacement. The success ratio of the surgical operation can be raised, and the pain of the patients can be reduced.
Description
Technical field
This utility model relates to a kind of novel aorta overlay film frame---gradually thin, bending aorta overlay film frame.
Background technology
The caliber expansion appears in aorta, when its diameter reaches the half as much again of aorta normal diameter, can think that formation aortic aneurysm, aortic aneurysm are modal aneurysms, comprise the true property of aorta, false aneurysm and dissecting aneurysm of aorta, aortic aneurysm is the serious disease that jeopardizes patient's life.The treatment aortic aneurysm adopted traditional therapeutic method of surgery in the past, and this method is effective, but operation wound is bigger, and operating time is long, and is dangerous high, operative mortality is 5%, and for the patient at advanced age who merges important organs such as the heart, brain, lung, kidney, its operative mortality is 20-60% especially.
Along with the development of interventional medicine, interventional therapy constantly is being applied in the treatment of aortic aneurysm as a kind of emerging treatment means, and wherein modal is aortic aneurysm endovascular graft exclusion.But advantages such as this method has, and wound is little, amount of bleeding is few, good effect, short repetitive therapy of hospital stays have especially reduced the incidence rate that traditional aneurysm is excised important organ complication such as the common heart in back, brain, lung, kidney.In lumen of vessels, use the artificial blood vessel of overlay film, aortic aneurysm wall and the isolated elimination aneurysm wall that reaches of blood flow are born the blood flow impact and keep the unimpeded purpose of aortic flow, block the blood supply and the source of nutrition of tumor simultaneously, cause neoplasm necrosis to disappear, to reach the purpose of treatment.
It is cylindrical that the aorta overlay film frame that generally uses mostly is straight tube in the market, and that the aorta physiological structure of human body is not the straight tube of standard is cylindrical, and this utility model provides a kind of novel aorta overlay film frame that meets the human physiological structure more.
Summary of the invention
The purpose of this utility model provides a kind of novel aorta overlay film frame, be gradually thin, the bending aorta overlay film frame that meets human dissection mechanism, it is simple to operation, and wound is little, be difficult for displacement, can improve the success rate of operation, reduces patient's misery.
For achieving the above object, this utility model is taked following design: a kind of novel aorta overlay film frame is connected by tubular metal support support that matches with the aortic blood tube shape and the artificial blood vessel that is coated on rack surface and to form.
Described tubular metal support is the Z font or the structure that assumes diamond in shape.
The utility model has the advantages that: little, the difficult success rate that is shifted, has improved operation of wound, minimizing patient's misery.
1, result of use is good: the employing memory alloy wire is weaved into Z font or diamond structure, can expand automatically with blood vessel wall closely to contact under body temperature, keeps the enough tension force of blood vessel wall.
2, performance is good: prop up and put up gradually thin, bending structure, more meet Human Physiology and dissect mechanism.Flexibly connect the compliance that increases support, make support in the smooth and easy release of aortic arch portion energy.The support longitudinal beam is strengthened structure, makes support be difficult for into the angle in aortic arch portion.Bracket end is the Phaleria macrocarpa shape, effectively avoids the support displacement.
3, stable performance: every layer of Z font support connects with memory alloy spring, need not weld or rivet, and do not influence the performance of material.
4, support covers artificial blood vessel outward, and blood flow and aneurysm wall is isolated, effectively prevents internal hemorrhage due to trauma.
Description of drawings
Fig. 1 is this utility model structural representation
The specific embodiment
As shown in Figure 1, aorta overlay film frame of the present utility model is made up of gradually thin tube-like metal rack 1 that matches with the aortic blood tube shape and the artificial blood vessel 2 that is coated on the intravascular stent surface.
The tubular metal support is made into by memory alloy wire, is Z font or argyle design, as shown in Figure 1.
Described aorta overlay film frame is gradually thin, bending structure, more meets Human Physiology and dissects mechanism.
Described Z font support is whenever saved memory alloy spring and is connected, and need not weld or rivet, and does not influence the performance of material.
Memorial alloy is softer, yielding under 0-10 ℃ of temperature, in aorta overlay film frame income conveyer device, and sends into human aortic tumor place, discharges support, and support is tightly sticked on the aortic blood tube wall, plays aorta wall and the isolated effect of blood flow.
Novel aorta overlay film frame gradually thin, bending more meets Human Physiology and dissects mechanism, flexibly connect the compliance that increases support, support still can smooth and easyly be discharged in aortic arch portion, the support longitudinal beam is strengthened structure makes support be difficult for into the angle in aortic arch portion, bracket end is the Phaleria macrocarpa shape, effectively avoid the support displacement, cover the artificial blood vessel material outward and can effectively prevent internal hemorrhage due to trauma.This New-support is simple to operation, wound is little, be difficult for displacement, improved the success rate of operation, has reduced patient's misery.
Claims (6)
1, a kind of novel aorta overlay film frame is characterized in that: by the tubular metal support that matches with the aortic blood tube shape and be coated on its surperficial artificial blood vessel and form.
2, novel aorta overlay film frame according to claim 1 is characterized in that: described aorta overlay film frame is gradually thin, bending structure.
3, novel aorta overlay film frame according to claim 1, it is characterized in that: described metal rack is Z font or argyle design.
