1. A simulator for practicing surgery or procedures involving the neck and airway, comprising:
a) a rigid base having a pattern of landmarks on a top surface thereof and integrally formed on the top surface of said rigid base, said rigid base having a size and shape to fit around a neck section of commercially available patient simulators or mannequins;
b) an anatomical structure/tissue layer to mimic the neck and airway of a person mounted on the top surface of the rigid base;
c) the anatomical structure/tissue layer comprised of:
skin mimicked by a polymer material having a tensile strength in a range from about 100 to about 650 psi, a modulus M100 in a range from about 5 to about 150 psi, and a Die B tear strength in a range from about 10 to about 200 pli (about 1.8 to about 26.3 kN/m);
fat mimicked by a polymer material having a tensile strength in a range from about 10 to about 600 psi, a modulus M100 in a range from about 1 to about 100 psi, and a Die B tear strength in a range from about 10 to about 150 pli (about 1.8 to about 8.8 kN/m);
lymph nodes mimicked by a polymer material having a tensile strength in a range from about 10 to about 600 psi, a modulus M100 in a range from about 1 to about 100 psi, and a Die B tear strength in a range from about 10 to about 150 pli (about 1.8 to about 8.8 kN/m);
muscles synthesized to mimic sternocleidomastoideoles, sternohyoid muscles, sternothyroid muscles, omohyoid muscles, thyrohyoid muscles, and cricothyroid muscles, the muscles comprised of a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 kN/m);
blood vessels synthesized to mimic anterior jugular veins, external jugular veins, internal jugular veins and carotid arteries, the blood vessels comprised of a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 KN/m);
a thyroid gland mimicked by a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 kN/m);
parathyroid glands mimicked by a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 kN/m);
laryngeal and tracheal cartilage synthesized to mimic each of the hyoid bone, thyroid cartilage, cricoid cartilage, tracheal rings, epiglottis, arytenoid cartilages, mimicked by a polymer material having a tensile strength in a range from about 100 to about 1000 psi, a modulus M100 in a range from about 10 to about 450 psi, and a Die B tear strength in a range from about 50 to about 250 pli (about 8.8 to about 43.8 kN/m);
mucosa mimicked by a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 kN/m);
recurrent laryngeal nerves mimicked by a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 kN/m);
trachealis muscle mimicked by a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 kN/m);
esophagus mimicked by a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 kN/m);
prevertebral fascia mimicked by a polymer material having a tensile strength in a range from about 50 to about 600 psi, a modulus M100 in a range from about 2 to about 135 psi, and a Die B tear strength in a range from about 10 to about 170 pli (about 1.8 to about 21 kN/m); and
wherein the pattern of landmarks provides a layout on the rigid base for proper and consistent attachment of one or more mimicked structures of the anatomical structure/tissue layer directly to the rigid base to mimic the human neck and airway.
