Description

Technical Field

[0001] The utility model relates to the technical field of vascular anastomosis training devices, and more specifically, to a simulation training device for simulating deep vascular anastomosis. Background Art

[0002] Current methods for vascular anastomosis primarily use sutures. While sutures are a safe and effective method, they require high technical skills from the surgeon. This is particularly true in cardiac surgery, where procedures involving the heart or deep large blood vessels are often performed deep within the heart and within confined spaces due to the limitations of bony structures that make up the chest cavity, such as the sternum and ribs. Therefore, mastering the skills to operate proficiently in deep, confined spaces is crucial.

[0003] In patent CN108320646A, a microneurosurgical deep vascular anastomosis surgery training table is used to train vascular anastomosis by placing an artificial blood vessel on a rotating plate. However, during use, it is not possible to simulate the anastomosis operation of blood vessels under different incision sizes, and the training effect is average. After the artificial blood vessel anastomosis practice, the practiced end of the artificial blood vessel needs to be cut off and the cut end of the artificial blood vessel needs to be realigned to facilitate the next practice. However, the application does not facilitate the movement of the artificial blood vessel, making it inconvenient to use.

[0004] In view of this, the existing problems are studied and improved, and a simulation training device for simulating deep vascular anastomosis is provided, aiming to solve the problems and improve the practical value through this technology. Utility Model Content
