Lifelike Inferior Vena Cava Medical Model for Surgery Training

The Inferior Vena Cava model can be used for laparoscopic surgery training for any type of surgeon.  The inferior vena cava model was constructed using synthetic materials that were benchmarked against mechanical properties of human tissue using the Human tissue Properties Database created at the University of Minnesota.  Synthetic materials give the model the touch and feel of an organ within the human body.  The model is reconstructed using anatomical structures as mold templates and, using the database of tissue behavior algorithms, the organs, vessels and tissue layers produced mimic real human structures, providing a much more realistic teaching tool than a traditional anatomical manikin.  This model simulates the inferior vena cava by mimicking the look and feel of the entire structure, as it would be within the human body.  The lifelike simulation allows for surgery training of medical students including vessel repair.

Vessel Repair Training with IVC Model

The IVC model helps to train medical students in the management of vessel injury and repair.  The inferior vena cava model also comes equipped with an adapter that can be connected to IV/irrigation tubing.  This is joined to an IV bag that is filled with artificial blood that will exit the wound, simulating blood loss.  All of this is secured within a holder that collects the blood that has leaked out of the injury in the inferior vena cava.  The model and holder are both secured within the laparoscopic training box.  Users are able to accurately experience what the organ is like and how it functions inside the human body.  It gives a better representation of the inferior vena cava than current medical models allow.
