Abstract
The present invention provides a surgical trainer having a simulated human tissue structure made of an elastomeric composition and having at least one reinforcing layer of a fibrous material. The surgical trainer preferably includes three areas for practicing surgical skills. The first is the abdominal area for practicing diagnostic peritoneal lavage. In a preferred embodiment for practicing this procedure, the surgical trainer includes a simulated tissue structure including a skin layer, a subcutaneous fat layer, an anterior rectus sheath layer, a muscle layer, a posterior rectus sheath layer, an extraperitoneal layer, and a peritoneum layer. Underlying the tissue structure, the trainer includes simulated abdominal organs within an abdominal cavity. The organs and cavity can be filled with simulated bodily fluids to lend more realism to the practice procedure. The second is the chest area. Chest tube insertion and pericardiocentesis are the procedures which can be performed on the trainer for this area. In addition to the simulated tissue structure on the exterior of the chest, the trainer includes additional tissue structure in the form of a layer of simulated tissue to mimic the intercostal muscle and the parietal pleura. To be more lifelike the trainer also includes inflatable lungs to simulate breathing, and ribs. For pericardiocentesis, a sternum, ribs, a heart and additional pericardium tissue structure are included. The heart and pericardium can be filled with simulated bodily fluids to mimic the real life procedure. The third is the neck area. Cricothyroidotomy is the procedure which can be performed on this part of the trainer. In addition to the simulated human tissue structure, the trainer includes a simulated cricoid cartilage, thyroid cartilage, and cricothyroid ligament in this area.
