Abstract

A method for producing a simulated animal organ includes: a shaping step of mixing a raw material containing mannan as a main component and water for gelatinization and shaping a gelatinized substance into a shape of an animal organ to obtain a shaped body; and a low temperature step of keeping the shaped body in a low temperature environment lower than a normal temperature. As a result, a simulated animal organ in a state extremely close to an actual animal organ is provided.

Claims (31)

1. A method for producing a simulated animal organ and training for surgery on the simulated animal organ comprising:

a shaping step of mixing a raw material containing mannan as a main component, water, and an electrolyte to the extent that the raw material has enough conductivity for a medical electric knife, for gelatinization and shaping a gelatinized substance containing the mannan to obtain a shaped body;

a low temperature step of keeping the shaped body at −5° C. or lower while freezing the water inside the shaped body, wherein the shaped body is frozen in the low temperature step until the mannan is changed into a mesh-like or fibrous form; and

a cutting step of cutting the simulated animal organ with the medical electric knife.

2. The method for producing a simulated animal organ and training for surgery on the simulated animal organ according to claim 1 ,

wherein the electrolyte is mixed at 1.0% by weight or less.

3. The method for producing a simulated animal organ and training for surgery on the simulated animal organ according to claim 1 ,

wherein the electrolyte is sodium chloride.

4. The method for producing a simulated animal organ and training for surgery on the simulated animal organ according to claim 1 ,

wherein a thickener is mixed in the shaping step.

5. The method for producing a simulated animal organ and training for surgery on the simulated animal organ according to claim 1 , further comprising:

a heating step of heating the shaped body and the water inside the shaped body until sterilized after the low temperature step.

6. The method for producing a simulated animal organ and training for surgery on the simulated animal organ according to claim 1 ,

wherein a foreign matter is contained inside the shaped body in the shaping step.

7. The method for producing a simulated animal organ and training for surgery on the simulated animal organ according to claim 1 , comprising:

a second shaping step of filling or stacking, inside or around the shaped body, a second material obtained by gelatinizing a mixture of a raw material containing mannan as a main component and water.

8. A simulated animal organ produced by the production method according to claim 1 .

9. A method for producing a simulated animal organ and using the produced simulated animal organ comprising:

a shaping step of mixing a raw material containing mannan as a main component and water for gelatinization and shaping a gelatinized substance containing the mannan to obtain a shaped body;

a low temperature step of keeping the shaped body at −5° C. or lower while freezing the water inside the shaped body, wherein the shaped body is frozen until the mannan is changed into a mesh-like or fibrous form in the low temperature step,

wherein an electrolyte is mixed with the water so that the electrolyte remains in the simulated animal organ in the shaping step such that the simulated animal organ can be stably cut by an electric knife; and

a cutting step of cutting the simulated animal organ with the electric knife.

10. The method for producing a simulated animal organ and training for surgery on the simulated animal organ according to claim 1 ,

wherein the shaped body is kept at −15° C. or higher in the low temperature step.

11. The method for producing a simulated animal organ and training for surgery on the simulated animal organ according to claim 1 , wherein the shaped body is kept at −15° C. or lower.

12. The method for producing a simulated animal organ and using the produced simulated animal organ according to claim 9 ,

wherein the shaped body is kept at −15° C. or higher in the low temperature step.

13. The method for producing a simulated animal organ and using the produced simulated animal organ according to claim 9 , further comprising:

a heating step of heating the shaped body and the water inside the shaped body until sterilized after the low temperature step.

14. The method for producing a simulated animal organ and using the produced simulated animal organ according to claim 9 ,

wherein the shaped body is kept at −15° C. or lower.
