Description

Heart hemostatic felt piece shearing device

Technical Field

The utility model relates to a shearing mechanism of medical field especially relates to a heart hemostasis felt piece shearing mechanism.

Background

Acute aortic dissection type a is the most aggressive disease of cardiovascular surgery, with mortality rates as high as 50% within 48 h. In recent years, the diagnostic level and surgical technique of aortic dissection are continuously improved, and the operation mode is determined after general intra-operative exploration. At present, the conventional large vessel operation of the acute type A aortic dissection in clinic comprises Sunshi operation, bentall operation, wheat operation, david operation and other operation modes. For large vessel surgery, hemostasis after vascular anastomosis is the key for determining success of the surgery, and an improved Sanming treatment method is generally used clinically, namely a felt sheet with the thickness of 0.8cm x 0.3cm is penetrated on a 5-0 polypropylene thread and is sewn on the outer membrane surface of a blood vessel, and then the felt sheet with the same size is used for reinforcing to form a sandwich, so that the artificial blood vessel and an autologous blood vessel are wrapped like the sandwich to play a role in hemostasis.
