The specific embodiment
The present invention is provided with three branches by trunk one end on the aortic arch stent, because three branches are located on the same end of trunk, makes between each branch closelyr, can not influence each other, and can adapt to different patients.
As shown in Figure 3, be first embodiment of the invention aortic arch stent sketch map, described aortic arch stent comprises trunk 10, first branch 11, second branch 12 and the 3rd branch 13, wherein said first branch 11, second branch 12 and the 3rd branch 13 are separately positioned on trunk 10 same ends, and described each branch is communicated with trunk 10 respectively.
In order to further specify the operation principle of the above embodiment of the present invention, specify the occupation mode of aortic arch stent.The aortic arch stent is compressed in the suitable induction system, the aortic arch stent stretches into ascending aorta by induction system from right subclavian artery or right common carotid artery, return and remove induction system, stent launches, trunk 10 places the ascending aorta place, first branch 11 places in the right common carotid artery and launches, and second branch 12 and the 3rd branch 13 launch in ascending aorta respectively.
The embodiment of the invention also proposes second embodiment on the basis of first embodiment.As shown in Figure 4 and Figure 5, described first branch 11 diameters are greater than the diameter of second branch 12, diameter less than the 3rd branch 13, the diameter sum of described first branch 11 and the 3rd branch 13 is suitable with the diameter of trunk 10, end at first branch 11, second branch 12, the 3rd branch 13 and trunk 10, and first branch 11, second branch 12 and the 3rd branch 13 and trunk 10 junctions are respectively equipped with the label 14 of X-ray opaque, and the label 14 of described X-ray opaque is used for determining that the aortic arch stent is in the intravital position of patient.The other end at aortic arch stent trunk 10 is provided with a bulge-structure, as the agnail structure, is used for the aortic arch stent is fixed on ascending aorta.
The embodiment of the invention also proposes the 3rd embodiment on the foregoing description basis, described aortic arch stent also comprises first module 1.As shown in Figure 6, be third embodiment of the invention first module 1 structural representation.Described first module 1 is a tubulose, and first module, 1 one end diameters are less than other end diameter, and first module 1 is carried out socket with described second branch 12, and wherein first module 1 is complementary than an end and second branch, 12 diameters of minor diameter.Be respectively equipped with the label 14 of X-ray opaque at first module, 1 two ends, when being used for determining first module 1 and 12 sockets of second branch, position between first module 1 and second branch 12.
Third embodiment of the invention also comprises second module 2.As shown in Figure 7, be third embodiment of the invention second module 2 structural representations.Described second module 2 is a tubulose, is arc, wherein said second module, 2 one end diameters less than with other end diameter, second module 2 is carried out socket with described the 3rd branch 13.Described second module 2 is complementary than an end and the 3rd branch 13 diameters of minor diameter.Be respectively equipped with the label 14 of X-ray opaque at the two ends of described second module 2, be used for determining position between second module 2 and its belled the 3rd branch 13.Other structures of aortic arch stent and annexation are constant.
In order to further specify the operation principle of the above embodiment of the present invention, specify the occupation mode of aortic arch stent.Aortic arch stent, first module and second module are compressed in respectively in the suitable induction system, under the supervision of special equipment, by observing the label 14 of X-ray opaque, determine aortic arch stent position by the position of determining label 14.The aortic arch stent is compressed in the suitable induction system, the aortic arch stent stretches into ascending aorta by induction system from right subclavian artery or right common carotid artery, return and remove induction system, stent launches, trunk 10 places the ascending aorta place, first branch 11 places in the right common carotid artery and launches, and second branch 12 and the 3rd branch 13 launch in ascending aorta respectively; The agnail structure of the end setting of the trunk 10 on the aortic arch stent makes the aortic arch stent be fixed on the ascending aorta place simultaneously; Insert first module 1 at innominate artery then, make the smaller diameter end of first module 1 and second branch 12 on the aortic arch stent carry out socket; After femoral artery is inserted second module 2, the 3rd branch 13 on smaller diameter end on second module 2 and the aortic arch stent is carried out socket.Determine label 14 positions of X-ray opaque by special equipment, make socket position between first module 1 and second branch 12 and second module 2 and the 3rd branch 13 all be no more than the label 14 of the X-ray opaque that second branch 12 and second branch 13 and trunk 10 junctions are provided with, thereby finish reparation human body ascending aorta, aortic arch, descending aorta pathological changes.As shown in Figure 8, be second branch 12 and the 3rd branch 13 and first module 1 and 2 sockets of second module after, the user mode of aortic arch stent.
The stent of aortic arch described in the invention described above embodiment adopts memory alloy wire or cutting metal pipe to make Z type ripple frame member, form different-diameter Z type ripple bracket loop through typing, the Z type ripple bracket loop of same diameter is fixed, and film laying makes Z type ripple bracket loop become first branch, second branch, the 3rd branch and major blood vessel shape.
Because first branch 11, second branch 12 and the 3rd branch 13 are located at trunk 10 same ends respectively, make between each branch tightr, simultaneously first module 1 and second module 2 respectively with the aortic arch stent on second branch 12 and the 3rd branch 13 carry out socket, influence each other between the aortic arch stent when reducing serial connection, adapt to different patients.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
