Before starting training during an actual operation, trainees should be familiar with the pelvic anatomy and simulate surgical procedures. Many simulators are available for virtual reality training of laparoscopic operations, but they are very expensive.The materials required to construct our model are sponges and colored wires sold in home improvement stores, providing superior cost-effectiveness. The model represents almost all peripheral vessels and nerves around the uterus, including minor vessels. Attaching and detaching vessels is easy, facilitating reconstruction of dissected vessels. The wires are easy to bend, ensuring high operability. This model allows simulation of laparoscopic radical hysterectomy in a dry box.Our model was superior to a two-dimensional picture for memorization of branching and positional relationships of blood vessels. Comparison of our model with actual operative videos showed that the dry box provided an identical surgical view of actual laparoscopic radical hysterectomy. We developed a peripheral bloodstream model of the uterus for repeated simulation of laparoscopic radical hysterectomy with an actual surgical view using ...
