US 2014/0370477 A1 · GALLBLADDER MODEL

Abstract

An anatomical model for surgical training is provided. The model includes a first layer simulating a liver and a second layer including a simulated gallbladder. A third layer having an inner surface and an outer surface is provided between the first and second layer. The outer surface of the third layer is adhered to the first layer at location around the simulated gallbladder and the simulated gallbladder is adhered to the inner surface of the third layer. A fourth layer is provided that overlays both the second layer and the simulated gallbladder. A frame is embedded within the first layer and is connectable to a support. The model provides a substantially upright projection of a simulated gallbladder and liver in a retracted orientation ideally suited for practicing laparoscopic cholecystectomy when inserted inside a simulated insufflated cavity of laparoscopic trainer.

a second layer having an inner surface and an outer surface;
the second layer defining a thickness between the inner surface and the outer surface;
the second layer having a second perimeter;
the second layer overlaying the first layer such that the outer surface of the second layer faces the inner surface of the first layer;
and
at least one second simulated anatomical structure;
the at least one second simulated anatomical structure defining a third perimeter around the at least one simulated anatomical structure;
