The surgical simulator contains a one-piece simulated uterus having a uterine fundus and body. A rigid hollow support base has a recess in its support surface that is complementary to the shape of at least a portion of the uterine fundus and body so that at least a posterior portion of the uterine fundus and body fit securely into the recess to retain the simulated uterus in position during use. Liquid can be introduced into the base to add weight, and the liquid can be heated to heat the simulated uterus to body temperature. The base can also provide a rigid hard tissue component that simulates the surface topography of the pelvic bone, portion of the spine, hip joints and heads of the femurs. The hard tissue component can be encased in an elastomeric material that simulates muscles and skin to practice obstetric procedures such as a C-section, insertion of an intrauterine tamponade balloon, insertion of an intrauterine contraceptive device, or insertion of compression sutures such as the B-Lynch suture.

1. A simulator, comprising: a one-piece simulated uterus comprising a uterine fundus and body;a rigid hollow base having a recess in a support surface, wherein the recess is complementary to the shape of at least a portion of the uterine fundus and body for holding the simulated uterus to a portion
1. A simulator, comprising: a one-piece simulated uterus comprising a uterine fundus and body;a rigid hollow base having a recess in a support surface, wherein the recess is complementary to the shape of at least a portion of the uterine fundus and body for holding the simulated uterus to a portion of a posterior depth of the artificial uterus;a port in the base that can be selectively opened to permit the introduction of a liquid into the base, and selectively closed to retain the liquid within the base, to selectively increase a weight of the base to stabilize the base and simulated uterus in a desired position. 2. The simulator of claim 1, wherein the simulated uterus comprises a simulated gravid or post-partum uterus. 3. The simulator of claim 1, wherein the simulated uterus includes fallopian tubes projecting outwardly or laterally from the junction of the uterine fundus and body on the anatomical left and right sides of the simulated uterus. 4. The simulator of claim 1, wherein the simulated uterus further comprises at least a portion of a simulated isthmus of two fallopian tubes projecting outwardly from the junction of the uterine fundus and body on the anatomical left and right sides of the simulated uterus and the recessed support surface further comprises a recessed portion that is complementary to a shape of the simulated isthmus of the two fallopian tubes. 5. The simulator of claim 1, further comprising a fabric mesh in an anterior wall of the uterine body that facilitates repeated incision and suturing of the uterine body. 6. The simulator of claim 1, further comprising a simulated vagina extending from the body of the simulated uterus, and the recess in the support surface further comprises a portion complementary to the shape of at least a posterior portion of the simulated vagina. 7. The simulator of claim 1, wherein the simulated uterus comprises an elastomeric silicone rubber having that provides a texture of the simulated uterus similar to human tissue. 8. The simulator of claim 7, wherein the elastomeric silicone rubber comprises a platinum-catalyzed room temperature vulcanization silicone rubber having a Shore A durometer hardness 5 of less than 10. 9. The simulator of claim 1, wherein the simulated uterus contains no latex. 10. The simulator of claim 1, wherein the base is a substantially hollow enclosure and the support surface comprises a top surface of the base for supporting the simulated uterus, a substantially flat bottom surface, and a continuous sidewall that extends between the top and bottom surfaces, wherein the port is located in the sidewall and is selectively closable by a removable cap that mates with the port. 11. The simulator of claim 1, wherein the simulated uterus is bulb-shaped. 12. The simulator of claim 1, wherein the base comprises a rigid human abdominopelvic simulator that simulates a surface of a pelvic bone, sacrum and coccyx, a portion of the lumbar spine, hip joints and heads of the femurs. 13. The simulator of claim 1, further comprising an elastomeric covering of the rigid base comprising simulated muscles and soft tissue. 14. The simulator of claim 13, wherein the simulated soft tissue comprises a simulated layer of skin that has a Shore A hardness of less than the Shore A hardness of the simulated uterus. 15. The simulator of claim 1, wherein the simulated uterus has a Shore A hardness of 2. 16. The simulator of claim 1, further comprising a liquid in the base. 17. The simulator of claim 16 wherein the liquid is heated to a temperature at or above 25° C. 18. The simulator of claim 1 wherein the simulated uterus comprises a chemically cross-linked silicone rubber or polyurethane elastomer that transmits ultrasound or is ultrasound lucent. 19. The simulator of claim 18 wherein the simulated uterus has a hardness between Shore 00: 35 to Shore A: 10. 20. The simulator of claim 1 wherein the simulator is made of compressible material. 21. The simulator of claim 1 wherein the uterus comprises uterine arteries. 22. The simulator of claim 1 wherein where the uterus comprises an anterior cervical lip.
