Abstract

The present invention provides a blood vessel closure device, comprising a support body frame and a sealing film, the support body frame includes a body and a stabilizing structure, the edge of the body protrudes from a plurality of oppositely arranged stabilizing structures, and the center of the body An intermediate structure is provided at the position, and the sealing film is laid on the outer surface of the support body frame; wherein, the body includes a plurality of pull rings and a plurality of pull wires, and the pull rings are arranged on the edge of the body One of the pull wires is connected to the two opposite pull rings; the present invention also provides a hemostasis system; the blood vessel closure device provided by the present invention can effectively achieve the purpose of hemostasis in interventional operations, Reduce operation time, improve difficulty and complexity of operation hemostasis.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a blood vessel closure device and a hemostasis system, in particular to a percutaneous large-diameter blood vessel closure device and a hemostasis system. Background technique [0002] In recent years, advances in interventional procedures such as transcatheter heart valve replacement or repair, thoracic aortic aneurysm repair, or cardiac ablation require insertion of a catheter through an incision in the patient's skin and underlying tissue to access the artery Or intravenous surgery. After the operation, the catheter needs to be removed from the blood vessel, so the blood vessel incision where the catheter is inserted must be closed. Due to the high blood pressure in the arteries, conventional methods such as pressing, suturing, and adhesives take a long time to stop bleeding, and are likely to cause unnecessary deformation of blood vessels, and it is difficult to achieve a good...
