Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a puncture fixation device for cardiovascular interventional surgery in children. Background Art

[0002] Cardiovascular interventional surgery is a minimally invasive surgery that uses catheter technology to diagnose and treat cardiovascular diseases. It mainly punctures the arteries or veins on the body surface and sends special catheters into specific parts of the heart or blood vessels for imaging examinations or treatments. Cardiovascular interventional surgery has the characteristics of small trauma and fast recovery, and has become one of the important means of treating cardiovascular diseases. In order to prevent bleeding and hematoma formation, the needle holes on the blood vessels and skin need some time to heal after the puncture operation. If the blood vessels or skin needle holes are not effectively compressed during the healing process, blood may seep out from the puncture point and accumulate in the subcutaneous tissue to form a hematoma, which will not only cause local pain and discomfort, but may also affect the clarity of the blood vessels and make it difficult to puncture again. Therefore, after cardiovascular interventional surgery, in order to ensure the later recovery effect, the puncture site needs to be pressed for a long time. At the same time, the puncture site should be observed for bleeding and hematoma. If subcutaneous bleeding occurs, it should be treated in time.
