This build provides all models necessary to print components to simulate the repair of a left-sided congenital diaphragmatic hernia. Some of the prints are for molds used to cast the silicone components of the model (heart/mediastinum, diaphragm, fat/soft tissue, and skin). Detailed instructions and diagrams are provided in the attached documentation. This module is intended to be combined with the infant surgery simulator platform (detailed in a separate build) but can be used with normal laparoscopes, trocars, and instruments found in most surgical simulation labs.
