Abstract
Изобретение относитс к медицинской технике, точнее, к кардиохирургии. Целью изобретени вл етс предотвращение осложнений и повышение прочности фиксации биологического трансплантата к опорному каркасу. Эта цель достигаетс тем, что опорный каркас снабжен фиксирующими элементами и представл ет собой полую изогнутую втулку с отверсти ми дл подшивки с одной стороны и манжетой с другой. При этом, фиксирующие элементы выполнены в виде кольца, расположенного на внешней поверхности доклапанного сосудистого русла биологического трансплантата, напротив отверстий дл подшивки каркаса. Биологический трансплантат на свободном конце послеклапанного сосудистого русла подшит "конец в конец" к синтетическому сосудистому протезу и покрыт синтетической обшивкой, а его фиксаци к опорному каркасу осуществл етс не менее, чем трем фиксирующими элементами. Таким образом, полностью исключаютс осложнени , св занные с перегибами и см ти ми биологического трансплантата в области фиброзного кольца, а, вследствии изменени характера фиксирующих напр жений увеличиваетс прочность фиксации биологического трансплантата к опорному каркасу.The invention relates to medical technology, more specifically, to cardiac surgery. The aim of the invention is to prevent complications and increase the strength of the fixation of a biological graft to the supporting framework. This goal is achieved in that the support frame is provided with locking elements and is a hollow bent sleeve with holes for binder on one side and a cuff on the other. At the same time, the fixing elements are made in the form of a ring located on the outer surface of the pre-valve vascular bed of the biological graft, opposite the openings for filing the scaffold. The biological graft at the free end of the collapsed vascular bed is hemmed "end to end" to the synthetic vascular prosthesis and is covered with synthetic casing, and its fixation to the support frame is carried out with at least three fixing elements. Thus, the complications associated with the kinks and smiles of the biological graft in the area of the fibrous ring are completely eliminated, and, due to the change in the nature of the clamping stresses, the strength of fixation of the biological graft to the support framework increases.
Description
Изобретение относитс к медицинской технике, точнее к кардиохирургии.The invention relates to medical technology, more specifically to cardiac surgery.
Цель изобретени - снижение послеоперационных осложнений и повышение надежности фиксации протеза.The purpose of the invention is to reduce postoperative complications and increase the reliability of fixation of the prosthesis.
На фиг.1 изображен протез артерии, .разрез; на фиг.2 - то же. без корпуса; на фиг.З - втулка, разрез.Figure 1 shows the prosthetic artery,. figure 2 - the same. without body; on fig.Z - sleeve, cut.
Протез артерии содержит биологиче- ский трансплантат 1, состо щий из после- клапанного сосуда 2. клапана 3 и доклапанного сосуда 4, причем ось биологического трансплантата 1 криволинейна и имеет радиус кривизны R, трансплантатом может быть аортальный или легочный комплексы . участки вен с клапанами, комплексы, образованные из твердой мозговой оболочки , широкой фасции бедра, перикарда и т.п. При этом все используемые биоматериалы проход т предварительную ферментно-хи- мическую обработку дл снижени антигенности .An artery prosthesis contains a biological graft 1 consisting of a post-valve vessel 2. valve 3 and a pre-valve vessel 4, the axis of biological graft 1 is curvilinear and has a radius of curvature R, the graft can be aortic or pulmonary complexes. portions of veins with valves, complexes formed from the dura mater, wide fascia of the thigh, pericardium, etc. In this case, all the biomaterials used undergo a preliminary enzymatic chemical treatment to reduce antigenicity.
Биологический тра нсплантат 1 фиксируетс на полой изогнутой втулке 5 с помощью отверстий 6. расположенных с одной стороны втулки 5 по ее периметру в два р да в шахматном пор дке (хот возможно и од- нор довое расположение) с диаметром 1- 2 мм. с другой стороны втулки 5 закреплена манжета 7. Втулка 5 может быть как цилинел юThe biological transplant 1 is fixed on a hollow bent sleeve 5 by means of holes 6. located on one side of sleeve 5 along its perimeter in two rows in a checkerboard pattern (although one position is possible) with a diameter of 1-2 mm. on the other side of the sleeve 5, the cuff 7 is fixed. The sleeve 5 may be like a cylinder

Средство 8 фиксации выполнено в виде овального кольца с круглым или эллиптическим поперечным сечением. Ширина b кольца составл ет 4-7 мм, а его длина 1 определ етс из выражени The tool 8 fixing made in the form of an oval ring with a round or elliptical cross-section. The width b of the ring is 4-7 mm, and its length 1 is determined from the expression
2(do2H-Q.)-n(3-5) 2 (do2H-Q.) - n (3-5)
где п - число фиксирующих элементов;where n is the number of fixing elements;
h - толщина стенки доклапанного сосудистого русла;h is the wall thickness of the pre-valve vascular bed;
do - наружный диаметр втулки.do is the outer diameter of the sleeve.
Свободный конец 9 участка послекла- панного сосуда 2 подшит конец в конец к синтетическому сосуду 10. Втулка 5 расположена внутри доклапаниого сосуда 4. То- рецМ втулки 5 находитс на рассто нии не менее 3 мм от основани створок клапана 3. Фиксаци осуществл етс шовным материалом 12. Биологический трансплантат 1 установлен в корпусе 13, соединенном с манжетой 7 и синтетическим сосудом 10. Дл создани плавного перехода от выход- ного отдела правого желудочка к биологическому трансплантату 1 толщина стенки втулки 5 при приближении к торцу 11 уменьшаетс .The free end 9 of the post-panned vessel 2 is hemmed end-to-end to the synthetic vessel 10. Sleeve 5 is located inside docking valve 4. Tore sleeve 5 is located at least 3 mm from the base of the valve leaves 3. Fixation is performed with suture material 12. The biological graft 1 is installed in the housing 13 connected to the cuff 7 and the synthetic vessel 10. To create a smooth transition from the output section of the right ventricle to the biological graft 1, the wall thickness of the sleeve 5 when approaching the end 11 is smart shaets.
Протез артерии работает следующим образом.Artery prosthesis works as follows.
При сокращении желудочка кровь выбрасываетс и через втулку 5, биологический трансплантат 1 и синтетический сосуд 10 поступает в аорту или легочную артерию.As the ventricle contracts, the blood is released through the sleeve 5, the biological graft 1 and the synthetic vessel 10 enters the aorta or pulmonary artery.
При этом клапан 3 открыт. После окончани выброса крови из желудочка клапан 3 закрываетс , предотвраща регургитацию крови.When this valve 3 is open. After the ventricular release of blood is completed, valve 3 closes, preventing blood regurgitation.
