Hernia model

摘要

A model for practicing transabdominal pre-peritoneal (TAPP) and total extraperitoneal (TEP) approaches for laparoscopic hernia repairs is provided. The model simulates an insufflated space between the abdominal muscles and peritoneum. A spring layer may be incorporated to provide a realistic resiliency to the model while in the simulated insufflated configuration. At least one hole is provided in the model from which synthetic tissue protrudes to simulate a hernia. The model is used to selectively simulate direct, indirect and femoral inguinal hernias as well as incisional hernias by removably placing the protruding simulated tissue into any one of several openings. The model contains all important anatomical structures and sits on a base frame or is connected to a rigid simulated pelvis. When located inside a laparoscopic trainer with an angled top cover, the model provides an ideal simulation for teaching and practicing laparoscopic hernia repair.

主权项

1. An anatomical model for surgical training, comprising:
a simulated abdominal wall located at a first end and having an inner surface and an outer surface; the simulated abdominal wall having at least one opening extending between the inner surface and the outer surface; at least a portion of a simulated pelvis at a second end having an inner surface and an outer surface; the simulated pelvis being connected to the simulated abdominal wall such that the inner surface of the simulated abdominal wall and the inner surface of the simulated pelvis define a common inner surface of the model; a first layer of synthetic tissue having a bottom surface and a top surface; the first layer overlaying at least a portion of the simulated pelvis and at least a portion of the simulated abdominal wall; the first layer adhered to at least a portion of the simulated pelvis and to at least a portion of the simulated abdominal wall; the first layer including at least one opening aligned with the at least one opening in the simulated abdominal wall; a second layer of synthetic tissue having a bottom surface and a top surface; the second layer overlaying at least a portion of the top surface of the first layer; the second layer including at least one opening aligned with the at least one opening in the simulated abdominal wall; a plurality of simulated tissue components positioned between the first layer of synthetic tissue and the second layer of synthetic tissue; at least some of the plurality of simulated tissue components being adhered at least in part to at least one of the first layer of synthetic tissue and the second layer of synthetic tissue; and a synthetic peritoneum overlaying the simulated abdominal wall and the simulated pelvis above the second layer of synthetic tissue; wherein at least a portion of the synthetic peritoneum is removably located inside one opening in the simulated abdominal wall.
