Description

Изобретение относится к' медицинской промышленности.The invention relates to the 'medical industry.

Известен протез для закрытия дефекта в тканях сердца, содержащий эластичные элементы, средства для 5 изменения геометрии и арматуру для краев [Г]. Для выполнения операции эластичные элементы в сложенном виде подводят к дефекту, размещают часть протеза внутри полости,.изменяют ге- 10 ометрию'эластичных элементов и фиксируют протез на ткани перегородки’.A known prosthesis for closing a defect in the tissues of the heart, containing elastic elements, means for 5 changes in geometry and reinforcement for the edges [G]. To perform the operation, the folded elastic elements are brought to the defect, a part of the prosthesis is placed inside the cavity, the geometry of the elastic elements is changed and the prosthesis is fixed on the septum tissue ’.

Данное устройство является наиболее близким к изобретению по технической сущности и достигаемому резуль^5 тату.This device is the closest to the invention in technical essence and the achieved result ^ 5 tattoos.

Недостатком протеза является ; сложность конструкции, большая продолжительность операции и возможность повреждения ткани арматурой протезам 20 Цель изобретения - упрощение конструкции, сокращение времени закрытия дефекта и снижение травматичности ,The disadvantage of the prosthesis is; the complexity of the design, the long duration of the operation and the possibility of damage to the tissue by the prostheses 20 The purpose of the invention is to simplify the design, reduce the time it takes to close the defect and reduce the morbidity,

Цель достигается тем, что эластич-25 ный элемент протеза выполнен цельным, средство для армирования одного края выполнено в виде жесткого кольца, средство для армирования друго*· го края—в виде плоской пружины с ме- 30 ханиэмом для сжатия, а диаметр пружины в свободном состоянии равен диаметру кольца и в два раза превосходит диаметр закрываемого дефекта.The goal is achieved by the fact that the elastic-25th element of the prosthesis is made whole, the means for reinforcing one edge is made in the form of a rigid ring, the means for reinforcing the other * · th edge is in the form of a flat spring with a compression mechanism, and the spring diameter the free state is equal to the diameter of the ring and twice the diameter of the defect to be closed.

На фиг,1 показан протез при его введении за перегородку, продольный разре; на фиг.2 - протез после установки; на фиг.З - пружины.In Fig. 1, a prosthesis is shown when inserted beyond the septum, a longitudinal section; figure 2 - prosthesis after installation; in Fig.Z - spring.

Цельный эластичный элемент 1 протеза выполнен из ткани и снабжен армирующим кольцом 2. Внутри протеза·· размещена плоская пружина 3, на которую до установки протеза надеты нити 4, стягивающие пружину через кольцо на конце держателя 5. Диаметр пружины 3 в свободном состоянии в , Два раза превосходит диаметр· закрываемого дефекта в тканях сердца 6 и равен диаметру кольца 2.The one-piece elastic element 1 of the prosthesis is made of fabric and equipped with a reinforcing ring 2. Inside the prosthesis ·· a flat spring 3 is placed, on which threads 4 are put on before installing the prosthesis, tightening the spring through the ring at the end of the holder 5. Spring diameter 3 in free state, Two times exceeds the diameter · of the closed defect in the tissues of the heart 6 and is equal to the diameter of the ring 2.

При операции протез вводят через дефект в перегородке (см. фиг.1), освобождают пружину 3 от нитей 4 и извлекают держатель 5. Протез остается в положений, показанном на фиг.2During surgery, the prosthesis is inserted through a defect in the septum (see Fig. 1), the spring 3 is released from the threads 4 and the holder 5 is removed. The prosthesis remains in the positions shown in Fig. 2

Claims

This invention relates to medical industry. A known prosthesis for closing a defect in heart tissues, containing elastic elements, means for changing the geometry and reinforcement for edges. fix the prosthesis on the septum tissue. This device is closest to the invention in terms of technical dryness and the resultant tattoo. The disadvantage of the prosthesis is the complexity of the design, the long duration of the operation and the possibility of damaging the fabric of the prosthesis reinforcement. The purpose of the invention is to improve the structure, shorten the time to close the defect and reduce trauma. The goal is achieved by the fact that the elastic element of the prosthesis is made solid, the means for reinforcing one edge is made in the form of a rigid ring, the means for reinforcing another in the form of a flat spring with a mechanism for compression, and the diameter of the spring in a free state is equal to the diameter of the ring and two times the diameter of the defect to be closed. Figure 1 shows the prosthesis when it is introduced over the partition, longitudinal section; figure 2 - prosthesis after installation; on fig.Z - springs. The one-piece elastic element 1 of the prosthesis is made of fabric and provided with a reinforcing ring 2. Inside the prosthesis is placed a flat spring 3, on which, prior to the installation of the prosthesis, there are yarns 4, which tighten the spring through the ring at the end of the holder 5. The diameter of the spring 3 in the free state is two times the diameter of the defect to be closed in the tissues of the heart b and equal to the diameter of the ring

2. During the operation, the prosthesis is inserted through a defect in the septum (see Fig. 1), the spring 3 is released from the threads 4 and the holder 5 is removed. The prosthesis remains in the positions shown in FIG. DETAILED DESCRIPTION OF THE INVENTION A prosthesis for closing a defect in a tissue; heart, mainly intercellular: l, ....

-

f;

KID DIVIDE, the elastic element contains means for changing geometry and reinforcement for edges, so that, in order to simplify the design, shorten the time of closing the defect and reduce trauma, the elastic element of the prosthesis is made whole, for reinforcing one edge made in the form of a rigid ring,

the means for reinforcing the other edge is made of a flat spring with a mechanism for compression, and the diameter of the spring in the free state is equal to the diameter of the ring and twice the diameter of the defect to be closed.
