Abstract

A model of a body part, e.g., liver, of which the internal structure can be observed easily; and others. In a liver model according to the present invention, the liver parenchyma is formed in the form of a frame to make it possible to observe the portal, veins, a tumor and others in the inside of the frame 31a easily. In addition, the liver model can be handled easily by gripping a gripping part provided at the lower end surface of the inferior vena cava, and the tumor is integrated with the liver model by means of a joint part. The liver model can be manufactured from a model material using a 3D printer on the basis of three-dimensional shape data for model manufacturing purposes, which are produced using an information processing device.

First claim

What is claimed is:

1. A model imitating a body part, comprising:
a frame; and
a body structural part,

both of which are formed from a forming material, wherein:
the frame is continuous linear,

and formed along at least a part of an outer surface of the body part; and
at least a part of the body structural part is inside the body part.

2. The model according to claim 1 , comprising:
a joint part that joins the body structural part to the other body structural part or the frame.

3. The model according to claim 1 , comprising:
a gripping part for gripping the model.

4. The model according to claim 1 , wherein:
the body part is a liver.

5. The model according to claim 1 , wherein:
the model is manufactured for a part of the body part.

6. A manufacturing system of a model imitating a body part, comprising:
an information processing device; and
a 3D printer, wherein:
the information processing device records three-dimensional shape data for the body part and three-dimensional shape data for a body structural part, at least a part of which is inside the body part, and generates three-dimensional shape data for a continuous linear frame that is formed along at least a part of an outer surface of the body part from the three-dimensional shape data for the body part; and
the 3D printer forms three-dimensional shapes of the frame and the body structural part corresponding to the three-dimensional shape data for the frame and the body structural part respectively from a forming material.

7. The manufacturing system according to claim 6 , wherein:
the information processing device generates three-dimensional shape data for a joint part that joins the body structural part and the other body structural part or the frame; and
the 3D printer forms a three-dimensional shape of the joint part corresponding to the three-dimensional shape data for the joint part from a forming material.

8. The manufacturing system according to claim 6 , wherein:
the information processing device generates three-dimensional shape data for a gripping part for gripping the model; and
the 3D printer forms a three-dimensional shape of the gripping part corresponding to the three-dimensional shape data for the gripping part from a forming material.

9. The manufacturing system according to claim 6 , wherein:
the body part is a liver.

10. An information processing device that generates three-dimensional shape data to be used in manufacturing a model imitating a body part using a 3D printer, wherein:
the information processing device records three-dimensional shape data for the body part; and
the information processing device generates three-dimensional shape data for a continuous linear frame that is formed along at least a part of an outer surface of the body part from the three-dimensional shape data for the body part.

11. The information processing device according to claim 10 , wherein:
the information processing device further records three-dimensional shape data for a body structural part, at least a part of which is inside the body part; and
the information processing device generates three-dimensional shape data for a joint part that joins the body structural part to the other body structural part or the frame.

12. The information processing device according to claim 10 , wherein:
the information processing device generates three-dimensional shape data for a gripping part for gripping the model.

13. The information processing device according to claim 10 , wherein:
the body part is a liver.

14. A manufacturing method for a model imitating a body part using an information processing device and a 3D printer, wherein:
the information processing device, which records three-dimensional shape data for the body part and three-dimensional shape data for a body structural part, at least a part of which is inside the body part, generates three-dimensional shape data for a continuous linear frame that is formed along at least a part of an outer surface of the body part from the three-dimensional shape data for the body part; and
the 3D printer forms three-dimensional shapes of the frame and the body structural part corresponding to the three-dimensional shape data for the frame and the body structural part from a forming material.

15. An information processing method that generates three-dimensional shape data to be used in manufacturing a model imitating a body part using a 3D printer, wherein:
the information processing device generates three-dimensional shape data for a continuous linear frame that is formed along at least a part of an outer surface of the body part from the three-dimensional shape data for the body part.

16. A non-transitory computer readable medium that operates a computer as an information processing device that generates three-dimensional shape data to be used in manufacturing a model imitating a body part using a 3D printer, wherein:
the information processing device generates three-dimensional shape data for a continuous linear frame that is formed along at least a part of an outer surface of the body part from the three-dimensional shape data for the body part.
