Abstract
The invention relates to an aortic arch graft with adjustable aperture, which comprises an aortic arch skeleton configured by connecting in series a plurality of corrugated Ni-Ti shape memory alloy wires (Z-shape wave), and branched vessel skeleton on the aortic arch skeleton, and medical coating attached to skeletons. The density of Z-shape wave in the distal end of the aortic arch skeleton is increased to enhance the radial supporting force of the skeleton. The Z-shape wave in the proximal end of the aortic arch skeleton is extended to connect with the conventional dacron woven aortic arch vessel graft. The inventive aortic arch graft is subjected to extrusion deformation at low temperature and has adjustable aperture, thereby facilitating the implantation in host vessel. In addition, it helps to reduce surgical time and prevent surgical complications (especially cerebral complications), thereby reducing pain of the patients.
Description
Technical field
The invention belongs to medical science artificial blood vessel graft field, especially a kind of adjustable artificial aortic arch graft.
Background technology
Along with the arrival of China's aging society, the sickness rate of chronic diseases such as hypertension, atherosclerosis presents tangible increase trend.One of consequence at a specified future date of these diseases is exactly to cause Secondary cases aorta and aortic arch portion pathological changes.According to statistics, 75% dissection of aorta patient suffers from hypertension, and 60% dissection of aorta belongs to Stanford A type interlayer (involving aortic arch portion); Atherosclerosis is the modal cause of disease of aortic arch portion true aneurysm.The sickness rate of China's dissection of aorta calculates according to this 0.5-2.95/10 10000 years, and the annual nearly 20000 dissection of aorta patients of China wherein involve the person of aortic arch portion and reach 12000 people.And postmortem is found, only has 15% dissection of aorta patient to be made a definite diagnosis before death, and nearly 85% patient fails accurately to be diagnosed, and therefore, the actual sickness rate of dissection of aorta is much higher possibly.At present, still do not have the morbidity statistics data of aortic arch true aneurysm, but this disease is mainly in old people and the family member that identical genetic background is arranged more than 60 years old.In addition, development along with China's process of industrialization, chest passivity wound is more and more sees, because aorta is only at aortic valve, arterial ligament and relatively fixing every three positions such as muscular artery ceasmas, then there is certain mobility at other positions, when chest is subjected to the passivity bump, produce inner membrance at above three positions easily and tear, form interlayer.Dissection of aorta is fallen ill rapidly, and the oncoming force is dangerous, the mortality rate height, and undressed Stanford A type dissection of aorta, 50% in morbidity death in back 48 hours.Therefore be the difficult point of cardiovascular surgical field.
Current, the standard method of aortic arch portion disease surgical intervention is blood vessel difference or " island " transplanting on operating substitution aortic arch+bow.The surgical technic that adopts remains the vascular anastomosis technology that Nobel physiology in 1912 and the medical science prize Alexis Carrel of winner founded in 1902.This kind method operating difficulty is big, the specification requirement height, and operating time is long, and ischemic time is long, and operative mortality and complication (especially cerebral complication) incidence rate can be in any more always.
Given this, from eighties of last century seventies, external part scholar once exempted to sew up the research of artificial blood vessel.But all, do not abandoned in succession after not entering clinical practice or entering clinical a period of time because the graft of being studied has shortcoming and the defective that himself is difficult to overcome.And these researchs all are confined to descending aorta, do not carry out the research of aortic arch graft.The development of less invasive techniques and endoluminal vascular treatment technology in recent years is rapid, and angiopathy can obtain medical treatment by the intracavity technology greatly.As the disease that descending aorta, ventral aorta, ilium blood vessel etc. are located, can obtain medical treatment by endovascular graft.But because aortic arch, makes himself disease in the uniqueness of aspects such as anatomy, biomechanics, hemodynamics, instantly also can't be by the treatment of intracavity technology.The present invention proposes the artificial aortic arch graft that a kind of novel adjustable of meter exempts to sew up, in the hope of solving the problem that current aortic arch operation exists.
Summary of the invention
The present invention will provide a kind of adjustable artificial aortic arch transplant, this graft utilize the characteristic of formative memory alloy can be at low temperatures crimp arbitrarily, regulate caliber size arbitrarily and easily implant host blood vessel in the Rhizoma Atractylodis Macrocephalae.
For achieving the above object, the technical solution used in the present invention is: a kind of adjustable artificial aortic arch transplant, comprise aortic arch main body framework, the aortic arch top set vascular skeleton that constitutes with the series connection of Z-shaped bellows-shaped by the niti-shaped memorial alloy silk and be coated on overlay film layer inside and outside the skeleton, be characterized in: this graft caliber size scalable, easily implant host blood vessel in the Rhizoma Atractylodis Macrocephalae; And far-end is not sewed up.
Main body framework far-end ripple density of the present invention increases, and is used to strengthen the radial support power of skeleton; The Z-shaped ripple of main body framework near-end is connected traditional terylene arcus aortae,artificial blood vessel, is convenient to vascular anastomosis; The branch vessel skeleton is adopted to be propped up by niti-shaped memorial alloy pipe hollow out and is configured to, and is used to strengthen adherent property; The material of overlay film layer is a kind of of ePTFE or polyester or derivatives thereof.
The present invention can be at low temperatures crimp arbitrarily, regulate caliber size arbitrarily and easily implant host blood vessel in the Rhizoma Atractylodis Macrocephalae.Clinical use can be simplified aortic arch portion surgical operation, reduces operating time, reduces postoperative complication (especially cerebral complication), thereby more effectively alleviates the pathological changes patient's of aortic arch portion misery.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the sketch map that the present invention inserts the aortic arch place.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As Fig. 1, shown in 2, a kind of adjustable artificial aortic arch graft of exempting to sew up, constitute aortic arch main body framework 3 by the niti-shaped memorial alloy silk with Z-shaped bellows-shaped series connection, niti-shaped memorial alloy pipe hollow out is propped up the overlay film layer 5 that is configured to aortic arch top set vascular skeleton 4 and is coated on the vascular skeleton and is formed.Wherein, the Z-shaped ripple density of main body framework 3 far-ends 2 increases gradually, to strengthen the radial support power of skeleton 3; The Z-shaped ripple negligible amounts of main body framework 3 near-ends 1 is so that be connected traditional terylene arcus aortae,artificial blood vessel 6.
The present invention can be at low temperatures crimp arbitrarily, regulate caliber size arbitrarily and easily implant host blood vessel in the Rhizoma Atractylodis Macrocephalae.Clinical use can be simplified aortic arch portion surgical operation, reduces operating time, reduces postoperative complication (especially cerebral complication), thereby more effectively alleviates the pathological changes patient's of aortic arch portion misery.
