(2. Manufacturing method of organ model 3)
Next, a method for manufacturing the organ model 3 will be described with reference to FIGS.

  In the present embodiment, it is assumed that the organ model 3 is a model simulating the liver. FIG. 3A schematically shows the shape of the liver, which includes an organ part 31 which is an external body part of an organ as a living body part, and a biological structure part such as a blood vessel other than the organ part 31. Reference numeral 32 in the figure denotes a blood vessel portion as an example of a anatomical site, and typically shows a portal vein of the liver. The blood vessel portion 32 protrudes from the inside of the organ portion 31 to the outside. The liver includes hepatic arteries, hepatic veins, and sometimes tumors, but the description thereof is omitted here.

In the present embodiment, when generating the three-dimensional shape data for manufacturing the organ model 3, the three-dimensional shape data of the organ part 31, the blood vessel part 32, etc. is input to the information processing apparatus 5 in advance as CAD data or the like. These three-dimensional shape data are CT (Computed Tomography) and MRI (Magnetic Resonanse).
DICOM (Digital Imaging and) obtained by scanning the liver of patients etc.
Communications from Medicine) data. Since the method is known (an example is described in Patent Document 1), description thereof is omitted.

  The solid line in FIG. 3B is an example of the three-dimensional shape data of the organ part 31, and the solid line in FIG. 3C is an example of the three-dimensional shape data of the blood vessel part 32. These three-dimensional shape data are determined with a predetermined origin as a reference, and the relative positional relationship is maintained. The dotted line in FIG. 3B indicates the position of the blood vessel part 32 with respect to the organ part 31, and the dotted line in FIG. 3C indicates the position of the organ part 31 with respect to the blood vessel part 32. The information processing apparatus 5 uses the 3D shape data of the organ part 31 and the blood vessel part 32 as described above to generate 3D shape data for manufacturing the organ model 3 by the 3D printer 7.

  FIG. 4 is a flowchart showing a procedure for generating three-dimensional shape data for producing the organ model 3. Each step in the figure is a process executed by the control unit 51 of the information processing apparatus 5 in accordance with a user input or the like.

  The information processing apparatus 5 first generates a three-dimensional shape A by subtracting the three-dimensional shape of the blood vessel portion 32 from the three-dimensional shape of the organ portion 31 and performing a set operation (S1). This three-dimensional shape A is shown in FIG. 32a corresponds to a blood vessel portion inside the organ portion 31, and the three-dimensional shape A is obtained by removing the blood vessel portion 32a from the organ portion 31.

  Further, the information processing apparatus 5 generates the three-dimensional shape B by taking the sum of the three-dimensional shape of the organ part 31 and the three-dimensional shape of the blood vessel part 32 by a set operation (S2). This three-dimensional shape B is shown in FIG. 32 b in the figure corresponds to a blood vessel portion protruding outside the organ portion 31, and the three-dimensional shape B is obtained by adding the blood vessel portion 32 b to the organ portion 31.

  Next, the information processing apparatus 5 subtracts the three-dimensional shape of the organ part 31 from the three-dimensional shape B by the set operation to obtain a difference, and generates the three-dimensional shape C of the blood vessel part 32b (S3). The three-dimensional shape C of the blood vessel portion 32b is shown in FIG. A dotted line is a portion corresponding to the organ part 31.

  Then, the information processing apparatus 5 synthesizes the three-dimensional shape A and the three-dimensional shape C, and at this time, performs data processing for the purpose of reinforcing the blood vessel portion 32b to generate the three-dimensional shape data of the organ model 3 (S4). ).

  That is, FIG. 5D shows a shape obtained by synthesizing the three-dimensional shape A and the three-dimensional shape C, but in this case, the blood vessel portion 32b is an organ only at the outer peripheral line of the boundary surface 320 of the blood vessel portions 32a and 32b. It does not contact part 31. In the present embodiment, as described later, since the blood vessel portion 32a is formed of a low-strength support material, the strength at the boundary surface 320 cannot be expected, and the blood vessel portion 32b may be structurally weak.

  Therefore, in this embodiment, in S4, the data is processed to reinforce the blood vessel portion 32b to generate a reinforcing portion, and the reinforcing portion is further synthesized into the three-dimensional shape of FIG. Generate dimensional shape data.

  FIG. 6A shows the generation of the reinforcing portion, and schematically shows the vicinity of the boundary surface 320 of the blood vessel portions 32a and 32b in FIG. 5D. As shown in FIG. 6A, in the present embodiment, a three-dimensional shape that covers the blood vessel portion 32 b outside the organ and is in contact with the organ portion 31 is generated, and this is used as the reinforcing portion 34.

  A method for generating the reinforcing portion 34 is not particularly limited. For example, as shown in FIG. 6B, a three-dimensional shape a is generated by expanding the outer surface of the blood vessel portion 32b by offsetting the outer side in the normal direction by a predetermined width, and the three-dimensional shape is generated from the three-dimensional shape a by a set operation. If the difference is obtained by subtracting B (see FIG. 5B), the reinforcing portion 34 can be generated.

  As described above, the three-dimensional shape data of the organ model 3 including the organ part 31, the blood vessel parts 32a and 32b, and the reinforcing part 34 is generated. This three-dimensional shape data is shown in FIG. Thereafter, the organ model 3 is manufactured by the 3D printer 7 using the three-dimensional shape data.

  FIG. 7 is a diagram showing the production of the organ model 3 by the 3D printer 7. In the present embodiment, the organ part 31 and the reinforcing part 34 (see FIG. 5E) are formed of the model material 71 (first material), and the blood vessel parts 32a and 32b (see FIG. 5E) are formed. It is formed of a support material 72 (second material).

  In the example shown in the figure, the arrangement of the three-dimensional shape data is determined so that the blood vessel portion 32b protruding outside the organ is located downward, and the model material 71 and the support material 72 are transferred from the nozzle head 73 on the stage 74 according to the three-dimensional shape data. Apply. The support material 72 is applied to a position for supporting the model material 71 in addition to the blood vessel portions 32a and 32b. After the model material 71 is cured, when the support material 72 at a position where the model material 71 is supported is removed, the organ model 3 shown in FIG. 8 is manufactured.

(3. Organ model 3)
As shown in FIG. 8, in this embodiment, the organ part 31 is formed of the model material 71, and the blood vessel part 32 a in the organ is formed of the support material 72. In addition, the blood vessel portion 32b protruding outside the organ is also formed by the support material 72, and the reinforcing portion 34 by the model material 71 is provided so as to cover the blood vessel portion 32b. The reinforcing part 34 is in contact with the organ part 31 and is continuous.

  For example, when an inkjet 3D printer 7 is used, a transparent (translucent) resin can be used as the model material 71 when the organ model 3 is manufactured, and the blood vessel portion by the support material 72 is provided inside the organ portion 31. It can be visually recognized how 32a is arranged. Furthermore, blood vessel portions 32a and 32b inside and outside the organ are continuous, and the blood vessel portion 32b outside the organ can be identified in the same manner as the blood vessel portion 32a, and these blood vessel portions 32a and 32b can be suitably expressed. In the FDM 3D printer 7, it is possible to use a transparent resin as the model material 71.

  Further, since the support material 72 has a lower strength than the model material 71 and can be easily removed, the blood vessel portion 32b protruding outside the organ is covered and reinforced by the reinforcement portion 34 made of the model material 71, thereby the blood vessel portion. The strength of 32b is improved. Although illustration is omitted, the aforementioned hepatic artery, hepatic vein, tumor, and the like are also formed of a support material.

  As described above, according to the present embodiment, the organ model 3 is manufactured using the model material 71 and the support material 72 for the organ part 31 and the blood vessel part 32a in the organ, and the blood vessel part 32b outside the organ is also expressed. This makes it suitable for reference during surgery and informed consent to patients, and for use in education and the like. Furthermore, the blood vessel portion 32b protruding outside the organ, which is considered to be likely to cause strength problems in the organ model 3, is covered and reinforced with the reinforcing portion 34 using the model material 71, and the reinforcing portion 34 is connected to the organ portion 31. A strong organ model 3 can be obtained by connection. In addition, the organ model 3 can be easily manufactured with an existing 3D printer.

  However, the present invention is not limited to this. For example, the organ model 3 is not limited to one in which the organ is molded as a single body, but can be molded in a state of being divided into a plurality of divided bodies. In this case, as shown in FIG. 9 (a), the information processing device 5 divides the three-dimensional shape data of the organ model 3 into a plurality of layers and performs molding by the 3D printer 7 for each layer to produce each divided body. That's fine.

  However, if the three-dimensional shape data of the organ model 3 is simply divided, the blood vessel portion 32a and the like are exposed on the division surface, and the support material 72 of the blood vessel portion 32a is lost. In order to prevent this, for example, as shown in FIG. 9B, the information processing device 5 generates the three-dimensional shape data of the cover portion 33 that covers the dividing surface of each divided body, and the three-dimensional shape of the cover portion 33. Three-dimensional shape data is generated by combining the data with the three-dimensional shape data of each divided body. Then, each divided body may be manufactured based on the three-dimensional shape data. As the three-dimensional shape data of the cover portion 33, for example, plate-like data having the same outer peripheral portion as the dividing surface may be generated.

  FIG. 10 is a diagram showing an organ model 3 ′ composed of each divided body. By forming the cover part 33 with the model material 71, it is possible to protect the dividing surface and to prevent the support material 72 of the blood vessel part 32a from being lost. In order to prevent exposure of the blood vessel portion 32a and the like on the dividing surface, the exposed portion may be blocked with parts made of the model material 71. For example, the three-dimensional shape data of a part having a predetermined thickness corresponding to the planar shape of the exposed portion of the blood vessel part 32a is newly generated, and the three-dimensional shape data of the part is covered and covered with this part. This is combined with the three-dimensional shape data of the divided body. And a division body is manufactured with the three-dimensional shape data after a synthesis | combination. At this time, the above parts are formed by the model material 71.

  In addition, although the model material 71 and the support material 72 are used for manufacturing the organ model 3 in this embodiment, it is also possible to manufacture the organ model 3 using materials such as various resins instead of these. Since the material of the anatomical site such as the blood vessel portion 32a may be lower in strength than the organ portion 31, a relatively wide range of materials can be used.

  In the present embodiment, an example of a liver organ is given as an example of a living body part, and a blood vessel is given as an example of a living body structure part. The organ model has many opportunities for use in surgery and the like, and the blood vessels are arranged in a complicated manner, which is particularly effective for using the present invention. However, the living body part may be a part of a human or animal body, and may be organs such as the heart and brain as well as the muscles of each part and organs such as the eyes. The anatomical site is not particularly limited as long as it is attached to the anatomical site and protrudes from the inside to the outside, and may be a nerve, bone, or the like in addition to blood vessels.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. The second embodiment will be described with respect to differences from the first embodiment, and description of similar points will be omitted.

(1. Organ model 3a)
FIG. 11 is a diagram showing an organ model 3a according to the second embodiment. This organ model 3a is different from the first embodiment in that the blood vessel portion 32b protruding outside the organ is formed by the model material 71 and the three-dimensional shape of the reinforcing portion 36.

(2. Manufacturing method of organ model 3a)
The method of manufacturing the organ model 3a is substantially the same as that described above, but differs in the point of generation of the reinforcing portion 36 in S4, and this will be described with reference to FIG. FIG. 12 is a diagram schematically showing the vicinity of the boundary surface 320 of the blood vessel portions 32a and 32b, similar to FIG.

  In the present embodiment, as shown in FIG. 12A, the information processing device 5 includes a reinforcing portion 36 that connects the root portion of the blood vessel portion 32b and the organ portion 31 so as to widen the root portion of the blood vessel portion 32b. Generated.

  A method for generating the reinforcing portion 36 is not particularly limited. For example, as shown in the left and right diagrams of FIG. 12B, a ring-shaped three-dimensional shape c having the cross-sectional center at the outer peripheral line 321 of the boundary surface 320 is generated, and the set operation is used to generate the ring-shaped three-dimensional shape c. If the difference is obtained by subtracting the three-dimensional shape B (see FIG. 5B), the three-dimensional shape of the reinforcing portion 36 can be generated.

  If the 3D printer 7 forms the organ part 31, the reinforcing part 36, and the blood vessel part 32b with the model material 71 and the blood vessel part 32a with the support material 72, the organ model 3a shown in FIG. 11 can be manufactured. In addition, as a reinforcement part, as shown to 36 'of FIG.12 (c), you may produce | generate the three-dimensional shape along the inner periphery of the blood vessel part 32a in an organ on the boundary surface 320. FIG. Also by this, the root part of the blood vessel part 32b and the organ part 31 are connected by the reinforcing part 36 '.

  In addition, as shown in FIG. 13A, the reinforcing portion 37 may be generated so as to cover the boundary surface 320 side of the blood vessel portion 32a. Also in this case, the root portion of the blood vessel portion 32 b and the organ portion 31 can be connected by the reinforcing portion 37.

  The method for generating the reinforcing portion 37 is not particularly limited. For example, the boundary surface 320 is offset by a predetermined width toward the blood vessel portion 32a, and a three-dimensional shape having both end surfaces at the positions of the boundary surface 320 before and after the offset is generated. This is performed for each direction indicated by the arrow in FIG. 13B, and a three-dimensional shape d is calculated by a logical sum of the generated three-dimensional shapes. If the difference is obtained by subtracting the three-dimensional shape A (see FIG. 5A) from the three-dimensional shape d by the set operation, the reinforcing portion 37 can be generated.

  Also in the second embodiment described above, the same effect as in the first embodiment can be obtained. Further, since the blood vessel portion 32b is formed of the model material 71, there is an advantage that the strength of the whole organ model 3a is increased.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these are naturally within the technical scope of the present invention.
