Сущность изобретени по сн етс чертежом , на котором схематично изображено устройство дл установки протеза в трубчатом органе, общий вид.The invention is illustrated in the drawing, which schematically shows a device for installing a prosthesis in a tubular organ, a general view.
Устройство дл установки протеза в трубчатом органе содержит съемный трубчатый кожух 1 с руко ткой 2, протез 3 со скобками 4 с щипами дл закреплени его на трубчатом органе, средство дл установки протеза, выполненное в виде эластичной трубки 5 с надувными баллонами 6, соединенных между собой и насосом 7 резиновой трубкой 8, неподвижное основание 9, подпружиненную каретку 10, установленную на основании , и гибкие т ги 11 дл фиксации. Устройство работает следующим образом .A device for installing a prosthesis in a tubular organ contains a removable tubular casing 1 with a handle 2, a prosthesis 3 with brackets 4 with tongs for fixing it on a tubular organ, means for installing a prosthesis made in the form of an elastic tube 5 with inflatable balloons 6 interconnected and pump 7 with a rubber tube 8, a fixed base 9, a spring-loaded carriage 10 mounted on the base, and flexible rods 11 for fixing. The device works as follows.
Протез 3 устанавливают предварительноProsthesis 3 pre-set
концами напротив каждого из соединенных эластичных баллонов 6, пропустив внутрь просвета эластичной трубки 5 гибкие т гиends opposite each of the connected elastic cylinders 6, passing inside the lumen of the elastic tube 5 flexible rods gi
5 11 от основани скобок 4 к подвижной подпружиненной каретке 10. Затем протез 3 сворачиваетс по спирали вокруг эластичной трубки 5 и вводитс в трубчатый кожух 1. При этом гибкие т ги 11 с помощью 0 каретки нат гивают, раст гива по оси и фиксиру тем самым протез 3 на эластичной трубке 5. Каретка гибких т г 11 фиксируетс в таком положении шпилькой 12 на неподвижном основании 9.5 11 from the base of the brackets 4 to the movable spring-loaded carriage 10. Then the prosthesis 3 is coiled in a spiral around the elastic tube 5 and inserted into the tubular casing 1. At the same time, the flexible rods 11 with 0 carriage tension, stretching along the axis and thereby fixing the prosthesis 3 on the elastic tube 5. The carriage of the flexible t 11 g is fixed in this position by the pin 12 on the fixed base 9.
У больного с установленным диагнозом (аневризма восход щей, нисход щей, брюшной аорты ниже отхождени почечных артерий ) из забрюшинного доступа слева выдел ют бифуркацию аорты, которую берут на турникеты и производ т поперечную аортото мню. В образовавшийс просвет ввод т устройство под рентгено-телевизионным контролем . При достижении проксимального конца аневризматического мещка в зоне сегмента аорты, не подверженного патологическому процессу, установленному с помощью дополнительных методов исследовани , вывод т эластичный трубчатый кожух 1 в нижнее положение. Протез 3 с пришитыми скобками 4 по концам удерживаетс гибкими т гами 11 на каретке т г шпилькой 12. После сн ти шпильки 12 сосудистый протез 3 остаетс зафиксированным неподвижно на эластичной трубке 5 уже с помощью подпружиненной каретки 10 гибких т г 11.In a patient with an established diagnosis (aneurysm of the ascending, descending, abdominal aorta below the discharge of the renal arteries), an aortic bifurcation is taken from the left retroperitoneal access, which is taken for turnstiles and a transverse aortotome is produced. The device is introduced into the resulting lumen under x-ray television control. Upon reaching the proximal end of the aneurysmal membrane in the area of the aortic segment that is not subject to the pathological process, established using additional research methods, the elastic tubular housing 1 is brought to the lower position. The prosthesis 3 with sewn brackets 4 is held at the ends by flexible arms 11 on the carriage by the hairpin 12. After removing the hairpin 12, the vascular prosthesis 3 remains fixed in place on the elastic tube 5 by means of the spring-loaded carriage 10 of the flexible legs of the gas 11.
Насосом 7 через резиновую трубку 8 подают физиологический раствор в эластичные баллоны 6, которые при помощи подпружиненной каретки 10 гибких т г 11 в радиальном направлении расправл ют сосудистый протез 3 до полного соприкосновени протеза с внутренней стенкой аорты, где с силой, создаваемой раздуваемыми физиологическим раствором баллонов 6, шипы скобок 4 обоих концов протеза 3 вонзаютс в стенку аорты. При этом подпружиненна каретка Ш под действием гибких т г i 1 перемещаетс по неподвижному основанию . При отсасывании физиологического раствора эластичные баллоны 6 занимаютPump 7 through a rubber tube 8 serves saline in elastic cylinders 6, which with the help of a spring-loaded carriage 10 flexible r 11 r in a radial direction straighten vascular prosthesis 3 until the prosthesis is in contact with the inner wall of the aorta, where with the force created by inflated saline 6, the spikes of the brackets 4 at both ends of the prosthesis 3 are inserted into the aortic wall. At the same time, the spring-loaded carriage W under the action of flexible t g i 1 moves along a fixed base. When sucking a physiological solution, elastic cylinders 6 occupy
исходное положение. Так как гибкие т ги 11 двойные, закрепленные на подпружиненной каретке 10, то дл извлечени из-под скобы 4 протеза 3 их перерезают по одной нити, после чего устройство извлекают из полости аорты, а рану аорты зашивают обычным способом.initial position. Since the flexible rods 11 are double, mounted on a spring-loaded carriage 10, for removing from 4 the prosthesis 4, they are cut one by one, after which the device is removed from the aortic cavity, and the aorta wound is sewn up in the usual way.
Операцию производ т в услови х управл е .мой гипотонии с применением антикоагул нтов . В послеоперационном периоде также необходима гипотензивна и антикоагул нтна терапи .The operation is performed under the conditions of my hypotension using anticoagulants. In the postoperative period, hypotensive and anticoagulant therapy is also necessary.
Предлагае.мое устройство обеспечивает воз.можность дистанционного внутриаортального введени и фиксации протеза в аневризматически расширенном участке аорты без вскрыти сосуда.The proposed device provides for the possibility of remote intra-aortic insertion and fixation of the prosthesis in the aneurysmatically expanded portion of the aorta without opening the vessel.
