Description

  The present invention relates to a human body model device used for training of a vascular anastomosis operation and the like.

  In principle, vascular suture is a single layer suture of all layers, and it is essential to join the intima. If the intima continuity is not maintained, blood coagulation and occlusion may occur. This is necessary not only for cardiovascular surgery, but also for intraperitoneal and intrathoracic surgery, blood vessel repair when bleeding, etc., and is a basic procedure that a doctor, especially a surgeon, must always learn.

  However, at present, in a surgeon training environment, the number of operations performed by each surgeon is extremely small. However, in general, it is very difficult to acquire and further improve advanced surgical techniques without clinical experience. It has been demanded.

  As training devices for conventional vascular anastomosis surgery, for example, there are devices shown in Patent Documents 1 and 2. In these devices, a surgical instrument such as a scalpel and forceps is inserted from a top plate corresponding to a chest wall of a human body into an opening corresponding to an incision formed in the top plate, and vascular anastomosis is performed in the thoracic cavity. This allows for a simulated experience of actual surgery.
