Abstract
Изобретение относитс к медицине и касаетс устройств дл замены кровеносных сосудов. Цель - предотвращение тромбообразовани . Протез кровеносного сосуда выполнен на основе синтетического волокна , при этом на его внутренней поверхности выполнены спиралевидные направл ющие в виде углублений и выступов, а высоты углублений и выступов относ тс к диаметру протеза как 1-10. Шаг винтовой линии, описываемой направл ющими, составл ет 1,5-4,0 диаметра протеза, при этом дл замещени аорты спиралевидные направл ющие расположены против часовой стрелки, а дл легочной артерии - по часовой стрелке. 1 з.п. ф-лы. 1 ил.This invention relates to medicine and relates to devices for replacing blood vessels. The goal is to prevent blood clots. The prosthesis of a blood vessel is made on the basis of synthetic fiber, with spiral-shaped guides in the form of depressions and protrusions on its inner surface, and the heights of the depressions and protrusions refer to the diameter of the prosthesis as 1-10. The pitch of the helix described by the guides is 1.5-4.0 times the diameter of the prosthesis, while for the replacement of the aorta the spiral-shaped guides are counterclockwise, and for the pulmonary artery - clockwise. 1 hp f-ly. 1 il.
Description
Изобретение относитс к медицине, в частности к сердечно-сосудистой хирургии, и касаетс протезов кровеносных сосудов.This invention relates to medicine, in particular cardiovascular surgery, and relates to prosthetic blood vessels.
Цель изобретени - предотвращение тромбообразоваии протеза.The purpose of the invention is the prevention of prosthetic thrombus formation.
На чертеже изображен протез кровеносного сосуда.The drawing shows the prosthesis of a blood vessel.
Протез состоит из комбинированной оболочки, наружна часть 1 которой выполнена путем плетени , а внтуренн часть 2 - путем в зани так, что на внутренней стенке протеза имеютс спиралевидные направл ющие в виде выступов 3 и углублений 4, В протезе, предназначенном дл протезировани аорты и артериальных сосудов, направл ющие расположены против часовой стрелки, а дл легочной артерии - по часовой стрелка.The prosthesis consists of a combination sheath, the outer part 1 of which is made by weaving, and the inner part 2 is made so that there are spiral-shaped guides in the form of projections 3 and recesses 4 on the inner wall of the prosthesis, intended for prosthetic aorta and arterial the vessels guiding are located counterclockwise, and for the pulmonary artery - clockwise.
Протез кровеносного сосуда работает следующим образом.The prosthesis of a blood vessel works as follows.
После имплантации протеза кровь движетс по спиралевидным направл ющим выступам 3 и углублени м 4, расположенным на внутренней части 2 протеза кровеносного сосуда. Спиралевидные направл ющие создают сохранение вращательного, закрученного спиралевидного потока крови. Наружна часть 1 эластичной оболочки (протеза) служит дл предотвращени перекрута протеза во врем работы (поскольку этому может способствовать вращательный поток крови по имплантату), так как наружна оболочка 1 имеет перпендикул рно и параллельно направленные волокна относительно потока крови и разнонаправленные по отношению к волокнам внутренней поверхности, выполненной по принципу в зани .After implantation of the prosthesis, the blood moves along spiraling projections 3 and depressions 4 located on the inside 2 of the prosthesis of the blood vessel. The spiral guides create the preservation of the rotational, swirling spiral blood flow. The outer part 1 of the elastic sheath (prosthesis) serves to prevent torsion of the prosthesis during operation (since the rotational blood flow through the implant can contribute to this), since the outer sheath 1 has perpendicular and parallel directional fibers relative to the blood flow and oppositely directed to the fibers surface, made according to the principle of under.
