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
