Gallbladder model for teaching and practicing surgical procedures

摘要

To provide an anatomical model for surgical training.SOLUTION: An anatomical model for surgical training has a first layer that mimics the liver and a second layer that includes a simulated gallbladder. A third layer having an inner surface and an outer surface is provided between the first layer and the second layer. The outer surface of the third layer is attached to the first layer at a location around the simulated gallbladder, and the simulated gallbladder is attached to the inner surface of the third layer. A fourth layer is provided covering both the second layer and the simulated gallbladder. It is connectable to the support with the frame embedded in the first layer. This model provides a substantially upright projection image of the simulated gallbladder and liver in a retracted orientation state that is optimal for practicing laparoscopic cholecystectomy when inserted into the simulated insufflation cavity of a laparoscopic training instrument.SELECTED DRAWING: Figure 1
