Abstract

Disclosed is a surgical simulator for teaching, practicing, and evaluating surgical techniques. Such a simulator may comprise a cassette of organs, blood vessels, and tissues that may be disposable. The simulator also comprises a hemodynamic simulator and a frame assembly, the frame assembly providing support for the cassette of organs as well as a fluid conduit through which simulated blood flow from the hemodynamic simulator may be connected to the blood vessels of the organs and related tissues. The hemodynamic simulator provides adjustable and variable pressures to the arteries and veins, as well as variable pulse rates, which can be programmed at settings chosen by an instructor or user.

Claims

1. A surgical simulator comprising a frame assembly, a hemodynamic simulator fluidly connected to the frame assembly, and an anatomical cassette fluidly connected to the frame assembly and hemodynamic simulator;

wherein the hemodynamic simulator is adapted to provide variable pressure flow of simulated blood to simulated arteries in the anatomical cassette and continuous pressure flow of simulated blood to simulated veins in the anatomical cassette; and

wherein the surgical simulator is programmable to provide variable rates of simulated blood pulse and pressure.

2. The surgical simulator of claim 1 further comprising a recording system.

3. A surgical simulator as in claim 2 wherein the recording system comprises at least one visible/infrared spectrum camera.

4. A surgical simulator as in claim 1 wherein the anatomical cassette comprises a uterus, ligaments, and blood vessels.

5. A hemodynamic simulator as in claim 1 comprising at least one air compressor and at least one pressurized fluid reservoir or accumulator.

6. A hemodynamic simulator as in claim 5 further comprising at least one regulator.

7. A surgical simulator, comprising:

a frame assembly;

a hemodynamic simulator comprising at least one air compressor and at least one pressurized fluid reservoir or accumulator, the hemodynamic simulator fluidly connected to the frame assembly; and

an anatomical cassette comprising simulated arteries, veins, and one or more of organs, tissues, and ligaments of an anatomical system, the anatomical cassette fluidly connected to the frame assembly and the hemodynamic simulator;

wherein the frame assembly is adapted to be a conduit through which simulated blood may flow between the hemodynamic simulator and the anatomical cassette; and

wherein the hemodynamic simulator is adapted to provide variable pressure flow of simulated blood to the arteries in the anatomical cassette and continuous pressure flow of simulated blood to the veins in the anatomical cassette; and

wherein the hemodynamic simulator is programmable to provide variable rates of simulated blood pulse and pressure.

8. A surgical simulator as in claim 7, wherein the anatomical cassette comprises simulated arteries, veins, and one or more of organs, tissues, and ligaments of an anatomical system associated with the mammalian abdominopelvic region.

9. A surgical simulator as in claim 8, wherein the anatomical system is the human reproductive system.

10. A surgical simulator as in claim 9, wherein the anatomical cassette further comprises one or more of simulated arteries, veins, organs, tissues, or ligaments of another anatomical system that is proximally positioned in the human body to the reproductive system.

11. A surgical simulator as in claim 10, wherein the reproductive system is the female reproductive system and the anatomical cassette comprises one or more of simulated uterus, ovary, fallopian tube, vagina, cervix, bladder, peritoneum, and omentum.

12. A surgical simulator as in claim 10, comprising a simulated pelvis and optionally, one or two simulated legs.

13. A surgical simulator as in claim 7, wherein the anatomical cassette comprises simulated arteries, veins, and one or more of organs, tissues, and ligaments of an anatomical system associated with the human thoracic region.

14. A surgical simulator, comprising:

a frame assembly;

a hemodynamic simulator comprising at least one air compressor and at least one pressurized fluid reservoir or accumulator, the hemodynamic simulator fluidly connected to the frame assembly; and

an anatomical cassette comprising (i) simulated arteries, veins, and one or more of organs, tissues, and ligaments of a human reproductive system; and

(ii) one or more of simulated arteries, veins, organs, tissues, or ligaments of another anatomical system that is proximally positioned in the human body to the reproductive system;

the anatomical cassette mechanically and fluidly connected to the frame assembly and fluidly connected to the hemodynamic simulator;

wherein the frame assembly is adapted to be a conduit through which simulated blood may flow between the hemodynamic simulator and the anatomical cassette; and

wherein the hemodynamic simulator is adapted to provide variable pressure flow of simulated blood to the arteries in the anatomical cassette and continuous pressure flow of simulated blood to the veins in the anatomical cassette; and

wherein the hemodynamic simulator is programmable to provide variable rates of simulated blood pulse and pressure.

15. A surgical simulator as in claim 14, wherein the reproductive system is the female reproductive system and the anatomical cassette comprises one or more of simulated uterus, ovary, fallopian tube, vagina, cervix, bladder, peritoneum, and omentum.
