Description

Изобретение относитс  к медицине, в частности к искусственным органам; и может быть применено дл  предупреждени  спаечных процессов между сердцем и перикардом после операций на сердце, трансплантации и реплантации сердца, или при временном подключени интракорпорально искусственного сердца .The invention relates to medicine, in particular to artificial organs; and can be used to prevent adhesions between the heart and the pericardium after heart surgery, transplantation and replantation of the heart, or when temporarily connecting an intracorporeal artificial heart.

Известен искусственный перикард, выполненный в виде оболочки из биологически нейтрального материала, дл  размещени  в нем искусственного сердца с целью предотвращени  тепловых ожогов окружающих тканей Ll3.An artificial pericardium, made in the form of a sheath of biologically neutral material, is known for placing an artificial heart in it in order to prevent thermal burns of the surrounding tissues Ll3.

Однако этот искусственный перикард не может быть использован с естественным сердцем дл  предотвращени  сращений между сердцем и окружающими ткан ми после хирургических операций на сердце.However, this artificial pericardium cannot be used with the natural heart to prevent adhesions between the heart and surrounding tissues after heart surgery.

.Развивающиес  спайки иногда исключают возможность повторных операций на сердце и трансплантацию сердца после временного подключени  интракорпорально искусственного сердца, что разрывает логическую цепь разрабатываемых этапов в проблеме повторных операций трансплантации и реплантации сердца. По вление спаек между работающим сердцем и окружающим его перикардом резко ухудшает сократительную функцию мьашцы сердца.. Developing adhesions sometimes exclude the possibility of repeated heart operations and heart transplants after temporary connection of an intracorporeal artificial heart, which breaks the logical chain of steps being developed in the problem of repeated heart transplantation and replantation operations. The appearance of adhesions between the working heart and the pericardium surrounding it sharply worsens the contractile function of the heart muscle.

Целью изобретени   вл етс  обеспечение возможности использовани  искусственного перикарда с естествен , ным сердцем и предотвращени  при это сращений между сердцем и окружающими ткан ми.The aim of the invention is to make it possible to use an artificial pericardium with a natural heart and prevent adhesions between the heart and the surrounding tissues.

Цель достигаетс  тем, что в искусственном перикарде, выполненномThe goal is achieved by the fact that in the artificial pericardium, performed

в виде оболочки из биологически ней трального материала, оболочка выполнена в виде открытой в сторону основани  сердца перфорированной капсулы и снабжена приспособлениемin the form of a shell made of biologically neutral material, the shell is made in the form of a perforated capsule open toward the base of the heart and equipped with

дл  фиксации ее на сердце. Кроме того, приспособление дл  фиксации выполнено в виде л мок дл  охвата дуги аорты.for fixing it on the heart. In addition, the fixation device is made in the form of a laser for covering the aortic arch.

На фиг. 1 показан предлагаемый искусственный перикард; на фиг. 2 тот же перикард, в полости которого находитс  сердце.FIG. 1 shows the proposed artificial pericardium; in fig. 2 the same pericardium, in the cavity of which the heart is located.

Предлагаемый искусственный перикард со5цержит-оболочку 1 в форме сердца с перфорационными отверсти ми 2 по всей поверхности. Дл  фиксации его на сердце имеютс  л мки 3. Полость 4 оболочки 1 открыта в сторо ну основани  сердца. После операции на сердце последнее помещают в полость 4 оболочки 1 искусственного перикарда и л мками 3, проведенными через поперечный синус, охватывают дугу аорты 5 и их концы подшивают к краю оболочки 1.The proposed artificial pericardium is a 5-core heart-shaped shell 1 with perforation holes 2 over its entire surface. For fixing it on the heart, there are lmki 3. The cavity 4 of the shell 1 is open to the base of the heart. After the operation on the heart, the latter is placed in the cavity 4 of the sheath 1 of the artificial pericardium and lame 3, carried out through the transverse sinus, cover the aortic arch 5 and their ends are hemmed to the edge of the sheath 1.

После проведенных манипул ций оболочка 1 искусственного перикарда надежно зафиксирована на сердце и покрывает всю его поверхность, создава  интерпозицик между наружной поверхностью сердца и внутренней поверхностью естественного перикарда, исключа  их срастание. Перфорационные отверсти  2 обеспечивают свободный жидкостно-биологический обмен между поверхностью сердца и полостью перикарда, в которой находитс , например , серозна  жидкость, облегчающа  скольжение стенок сердца при сокращении .After these manipulations, the sheath 1 of the artificial pericardium is securely fixed to the heart and covers its entire surface, creating an interposition between the outer surface of the heart and the inner surface of the natural pericardium, excluding their intergrowth. Perforations 2 provide a free liquid-biological exchange between the surface of the heart and the pericardial cavity, in which, for example, there is a seronec fluid that facilitates the sliding of the walls of the heart during contraction.

Предлагаемый искусственный перикард прост по конструкции и в применении , удобен и надежен в работе, не нарушает естественные физиологически процессы между органами, исключает срастание поверхности оперированного органа с окружающими его ткан ми, значительно улучша  результат проводимой операции.The proposed artificial pericardium is simple in design and use, convenient and reliable in operation, does not violate the physiological processes between organs, eliminates the fusion of the surface of the operated organ with its surrounding tissues, greatly improving the result of the operation.
