Deployable formula heart hemostasis device

Technical Field

The utility model relates to a cardiac surgery field, concretely relates to deployable formula heart hemostasis device.

Background

A large group of heart diseases is represented by various "defects" or "leaks" in the heart, including both ventricular septal defects, which account for as much as 20% of all congenital heart diseases, and perivalvular leaks, which occur after aortic or mitral valve replacement. At present, the innovative method for treating the diseases is to directly puncture the skin surface of the chest, and then further puncture the ventricle to enter the interior of the heart through image guidance to complete the occlusion treatment. However, the biggest problem faced by the method is that after the internal blockage of the heart is finished and the catheter is withdrawn, wound passages are generated on the surface of the ventricle, and hemostasis is needed. Since the surface of the heart has only a small wound with a diameter of a few millimeters, it is difficult for a surgeon to close the wound left on the surface of the ventricle by a conventional direct-vision suture method, and an occlusion device is needed to perform occlusion hemostasis specifically for the wound under a minimally invasive condition.

Meanwhile, the doctor often needs to perform temporary hemostasis on the heart of a patient in the heart operation process, the existing hemostatic forceps are simple to perform hemostasis, and the hemostatic forceps cannot be fixed, so that the hemostatic effect is poor, the hemostatic pressure cannot be accurately controlled, and the problem that the temporary hemostasis is performed in the heart surgery operation cannot be normal is solved. Therefore, there is a need for further research based on existing cardiac surgery to provide a new cardiac hemostasis device.
