Изобретение относитс к медицине, а именно, к области кардиохирургии, и может быть использовано дл коррекции недостаточности митрального клапана.The invention relates to medicine, namely to the field of cardiac surgery, and can be used for the correction of mitral valve insufficiency.
Известен протез дл клапана сердца, состо щий из каркаса в виде жестокого кольца , повтор ющего форму основани клапана и оболочки 1Одной из частых причин митральной недостаточности вл етс расширение фиброз ного кольца клапана. Равномерное суживание основани клелана путем имплантации металлического кольца ликвидирует недостаточность кл 1пана. Однако &то устройство имеет тот недостаток, что оно ригидно и жестко фиксирует фиброзное кольцо клапана в одном положении. Между тем известно, что в замыкательной функции кроме створок клапана и подклапачных структур большое значение имеет сближение во времени сие- толы фиброзной основы аортальной и муральной створок митрального клапана. В результате клапан во врем систолы принимает вид шепи. Жестка фиксаци фиброзного копьцакпапана искпючоег подобный механизм,A prosthetic heart valve prosthesis consisting of a skeleton in the form of a rigid ring that follows the shape of the base of the valve and the sheath. One of the common causes of mitral insufficiency is the expansion of the fibrous ring of the valve. The uniform narrowing of the base of the clan by implantation of a metal ring eliminates the failure of the CL of the pan. However, & that device has the disadvantage that it is rigid and rigidly fixes the fibrous ring of the valve in one position. Meanwhile, it is known that, in the closure function, in addition to the valve leaflets and sub-valve structures, the convergence in time of the seal of the fibrous base of the aortic and mural mitral valve is of great importance. As a result, the valve during systole takes the form of whispers. The rigid fixation of the fibrous lance is similar to a mechanism similar to
Кроме того, конструкци протеза не исключ прорезывание швов.In addition, the design of the prosthesis does not exclude the eruption of the seams.
Цель изобретени - обеспечение возможности сближени фибрознсй клапана во врем систолы и снижение риска прорезывани швов.The purpose of the invention is to provide the possibility of convergence of the fibrous valve during systole and reduce the risk of eruption of the seams.
Поставленна цель досгагаетс тем, чуо часть каркаса клапана, определ юща конфигурацию кольца, повтор ющего форму основани клапана, выполнена жес1к.о&, а замы кающа часть каркаса выполнена гибкой, например, в виде пружины.The goal is achieved by the fact that the choo part of the valve cage, defining the configuration of the ring that follows the shape of the base of the valve, is rigid, and the closing part of the cage is made flexible, for example, in the form of a spring.
На фиг. 1 изображен протез дл клапана сердца; на фиг. 2 - сечение по А-А на фиг. 1; на фиг. 3 - сечение по Б-Б на фиг. 1.FIG. 1 shows a prosthesis for a heart valve; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.
Протез состоит из каркаса в виде кольца 1, повтор ющего форму основани клапана и оболочки 2. Часть 3 каркаса, определ юща конфигурацию кольца, повтор ющего форму основани клапана, выполнена жест кой, а замыкающа часть 4 каркаса - гибкой , например, в виде пружины.The prosthesis consists of a frame in the form of a ring 1, which repeats the shape of the base of the valve and the sheath 2. Part 3 of the frame, which defines the configuration of the ring, follows the shape of the base of the valve, is rigid, and the closing part 4 of the frame is flexible, for example, in the form of a spring .
Таким образом гибка часть рротеза позвол е-т фиброзной основе створок совершать естественные колебательные движе-Thus, the flexible part of the prosthesis allows e-fibrous basal flaps to make natural oscillatory movements.
НИЯ aa счет прогибани гибкой час-ш, что поавои ет сердцу работать в услови х, блиашш к естественным.NIA aa account of the deflection of a flexible hour, which makes it possible for the heart to work in conditions that are closer to the natural.
