Abstract

The invention discloses a plugging device for cardiac surgery atrial septal defect treatment. The plugging device comprises a left disc, a right disc, a columnar blocking part located between the left disc and the right disc, and a pore passage penetrating through the left disc, the right disc and the columnar blocking part; the inner side surface of the left disc and the inner side surface of the right disc are provided with anti-release films made of a silica gel material correspondingly; and the anti-release films are in a circular ring shape and are arranged on the columnar blocking part in a sleeving mode. According to the plugging device, the anti-release films made of the silica gel material are additionally arranged, the columnar blocking part is sleeved with the circular ring-shaped anti-release films, the left disc and the right disc clamp the atrial septum together after the plugging device is placed in; meanwhile, the two anti-release films are arranged on the two sides of the atrial septum respectively and tightly attached to the atrial septum, and therefore the static friction force between the plugging device and the atrial septum can be increased; and the positioning stability of the device can be effectively improved, and falling is prevented.

Description

technical field [0001] The invention relates to the medical field of cardiac surgery, in particular to a blocking device for treating atrial septal defect in cardiac surgery. Background technique [0002] Atrial septal defect (ASD) is a common congenital heart disease. It is the abnormality of the original atrial septum during embryonic development, resulting in a gap between the left and right atrium. In the early stage of ASD, surgery or minimally invasive interventional closure can cure the disease, but when the disease progresses to the stage of severe pulmonary hypertension, the opportunity for surgery will be completely lost. Because even if the atrial septal defect is closed at this time, the pulmonary hypertension will not decrease, and even further increase the occurrence of cardiovascular malignant events. A large number of left-to-right shunt pulmonary vessels in congenital heart disease have been irreversibly changed. Forcibly closing the defect will lead to now...
