Description

Technical Field

[0001] The present application relates to the technical field of medical simulation models, and in particular to a surgical bionic model component. Background Art

[0002] At present, in medical surgeries on the human nose, medical staff usually plan the surgical plan based on information such as the patient's nose computed tomography (CT) or magnetic resonance imaging (MR). Since the human nose structure is relatively complex and the risk of nose surgery is relatively high, the nose surgery bionic model components customized for patients can provide medical staff with preoperative plan planning and surgical simulation, and can also provide medical beginners with opportunities for surgical training and teaching demonstrations.

[0003] However, the structural adjustability of existing nasal surgery bionic model components is poor, making it difficult to simulate the postures that a living organism needs to maintain during different nasal surgeries, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the present application provides a surgical bionic model component. The surgical bionic model component of the present application has freedom of movement. The user can adjust the position of the model to be operated relative to the user, so that the surgical bionic model component can simulate the posture that the organism needs to maintain in different nasal surgeries, and the user experience is better.

[0006] Since the movable part includes an active structure, the user can make the internal structure of the movable part relatively movable according to different surgical needs to adjust the position of the model to be operated relative to the base, or to adjust the position of the model to be operated relative to the user. In the process of the user using the surgical bionic model assembly, the user does not need to adjust his posture significantly, or in other words, the user can put himself in a more comfortable posture, and the user can perform more accurate surgical training, teaching demonstration or surgical plan planning when the model to be operated is more in line with the posture required for the actual surgery, and the user has a better user experience; and since the model to be operated includes a first structural part and a second structural part that are detachably connected, the setting is convenient for the user to replace only one of the first structural part and the second structural part after using the model to be operated to simulate the surgery, without replacing the other, so that part of the structure in the model to be operated can be reused, that is, the model to be operated has the effect of less waste of resources. The setting is also convenient for the user to replace at least one of the first structural part with different pathological conditions (such as tumors, cysts or polyps) and the second structural part with different pathological conditions (such as tumors, cysts or polyps) to meet the needs of simulating different surgeries.

[0066] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0067] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0068] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0069] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0070] The embodiment of the present application provides a surgical bionic model component, which relates to the field of medical training technology. The surgical bionic model component is mainly used for surgical simulation purposes such as surgical training, teaching demonstration or surgical plan planning, which helps to improve the learning efficiency of medical beginners and also helps to improve the success rate of doctors' operations.

[0071] Since there are many different actual lesion locations of the same organ of an organism (human or animal), the doctor has different directions of operation to be performed for different lesion locations, and accordingly, the posture of the organism undergoing surgery on the operating table is also different. Therefore, the surgical bionic model component provided in the embodiment of the present application is a surgical bionic model component with adjustable posture to meet different surgical needs.

[0072] Please refer to Figure 1 As shown, the surgical bionic model assembly 10 includes a base 1, a movable part 2 and a model to be operated 3, the movable part 2 includes a movable structure, the base 1 is connected to the movable part 2, and the movable part 2 is connected to the model to be operated 3.

[0073] Please refer to Figure 2 As shown, since the movable part 2 includes a movable structure, the user can make the internal structure of the movable part 2 relatively movable according to different surgical needs to adjust the position of the model 3 to be operated relative to the base 1, or to adjust the position of the model 3 to be operated relative to the user. In the process of the user using the surgical bionic model assembly 10, the user does not need to adjust his or her posture significantly, or in other words, the user can put himself or herself in a more comfortable posture, and the user can perform more accurate surgical training, teaching demonstration or surgical plan planning when the model 3 to be operated is more in line with the posture required for the actual surgery, and the user has a better user experience.

[0074] The movable structure may include a rotating structure, that is, the internal structure of the movable part 2 can rotate relatively around a set axis. Of course, the movable structure may also include a sliding structure, that is, the internal structure of the movable part 2 can slide relatively along a set direction. Furthermore, the movable structure may also include a spiral rotating structure, that is, the internal structure of the movable part 2 can spirally rotate along a set spiral line.

[0075] In addition, please refer to Figure 1As shown, the model to be operated 3 of the surgical bionic model assembly 10 of the embodiment of the present application includes a first structural member 31 and a second structural member 32 that are detachably connected, and at least one of the first structural member 31 and the second structural member 32 is detachably connected to the movable member 2. This arrangement facilitates the user to replace only one of the first structural member 31 and the second structural member 32 after using the model to be operated 3 to simulate surgery, without replacing the other, so that part of the structure in the model to be operated 3 can be reused, that is, the model to be operated 3 has the effect of less waste of resources. This arrangement also facilitates the user to replace at least one of the first structural member 31 with different pathological conditions (such as tumors, cysts or polyps) and the second structural member 32 with different pathological conditions (such as tumors, cysts or polyps) to meet the needs of simulating different surgeries.

[0076] In addition, the connection between the movable part 2 and the first structural part 31 can be a detachable connection. The detachable connection method includes at least one of a snap-on connection, a magnetic connection, a riveted connection, a bolted connection and an adhesive connection. The detachable connection of any connection structure mentioned in the subsequent content of this article also includes at least one of a snap-on connection, a magnetic connection, a riveted connection, a bolted connection and an adhesive connection, which will not be described in detail in the subsequent content. The connection between the movable part 2 and the first structural part 31 can also be a fixed connection, for example, the first structural part 31 is directly injection molded, cast or 3D printed on the movable part 2.

[0077] Similarly, the connection between the movable part 2 and the second structural part 32 can be a detachable connection. The connection between the movable part 2 and the second structural part 32 can also be a fixed connection, for example, the second structural part 32 is directly injection molded, cast or 3D printed on the movable part 2.

[0078] From the above content, it can be known that the connection relationship between the movable part 2 and the model to be operated 3 can include the following five types:

[0079] The first type of connection relationship: the first structural member 31 is detachably connected to the movable member 2 , and the second structural member 32 is not connected to the movable member 2 .

[0080] The second type of connection relationship: the first structural member 31 and the second structural member 32 are respectively detachably connected to the movable member 2 .

[0081] The third type of connection relationship: the first structural member 31 is detachably connected to the movable member 2 , and the second structural member 32 is directly formed by injection molding, casting or 3D printing on the movable member 2 .

[0082] The fourth type of connection relationship: the first structural member 31 is not connected to the movable member 2 , and the second structural member 32 is detachably connected to the movable member 2 .

[0083] The fifth type of connection relationship: the first structural member 31 is directly formed on the movable member 2 by injection molding, casting or 3D printing, and the second structural member 32 is detachably connected to the movable member 2 .

[0084] The following content of this article mainly describes the connection relationship between the movable part 2 and the model to be operated 3 by taking the first type of connection relationship as an example.

[0085] Furthermore, the connection between the base 1 and the movable member 2 may be a movable connection, and the movable connection may include a rotation connection and / or a sliding connection. Of course, the connection between the base 1 and the movable member 2 may be a detachable connection.

[0086] The model 3 to be operated of the surgical bionic model component 10 of the embodiment of the present application may include a nose model 321, which is a simulated biological nose structure (such as a human nose structure). The user can use the surgical bionic model component 10 to conduct training and teaching demonstrations on nose surgery.

[0087] In other embodiments, the model to be operated 3 may also include other biological organ models of a living body, which is not limited here.

[0088] Optionally, see Figure 1 , Figure 2 , Figure 3a , Figure 3b and Figure 3c As shown, the movable part 2 includes a first base 21 and a first connecting part 22, the base 1 is connected to the first base 21, the first base 21 is rotatably connected to the first connecting part 22, and the first connecting part 22 is detachably connected to the first structural part 31 of the model 3 to be operated.

[0089] Please refer to Figure 3a , Figure 3b and Figure 3c As shown, the user can rotate the first base 21 and the first connecting member 22 relative to each other, thereby rotating the model 3 to be operated relative to the first base 21, so that the user can perform more accurate surgical training, teaching demonstrations or surgical plan planning in a posture that is more in line with the actual surgical posture.

[0090] The first base 21 and the first connecting member 22 can be arranged around Figure 3a , Figure 3b and Figure 3cThe rotation axis O1 shown in the figure rotates relatively, and the rotation axis O1 is the axis of the first base 21. The rotation axis O1 can be parallel to the height direction Z of the surgical bionic model component 10. The first base 21 and the first connecting member 22 can deflect and rotate relative to each other. The value range of the rotation angle α between the first base 21 and the first connecting member 22 relative to each other can be within 0° to 360°. The value of the rotation angle α can be 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, 190°, 200°, 210°, 220°, 230°, 240°, 250°, 260°, 270°, 280°, 290°, 300°, 310°, 320°, 330°, 340°, 350° or 360°.

[0091] In other embodiments (not shown in the figure), the rotation axis O1 may intersect with the height direction Z of the surgical bionic model component 10. In detail, the rotation axis O1 may be perpendicular to the height direction Z of the surgical bionic model component 10, and accordingly, the numerical range of the rotation angle α of the first base 21 and the first connecting member 22 relative to each other may be within 0° to 270°, and the numerical value of the rotation angle α may specifically be 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, 190°, 200°, 210°, 220°, 230°, 240°, 250°, 260° or 270°.

[0092] In addition, the first connecting member 22 may include a movable structure or may not include a movable structure. If the first connecting member 22 includes a movable structure, the movable structure may include a rotating structure and / or a sliding structure.

[0093] Furthermore, the first base 21 and the base 1 can be detachably connected.

[0094] In addition, the main structure of the first base 21 can be a disc-shaped structure, such as a circular disc or an elliptical disc. The bottom end surface of the first base 21 can abut against the surface of the base 1. This arrangement makes it difficult for the movable member 2 to tip over relative to the base 1, that is, the structural stability is high. The top end surface of the first base 21 supports the main structure of the first connecting member 22.

[0095] In other embodiments (not shown in the figures), the top surface of the first base 21 may be provided with an inwardly recessed groove, and the bottom of the first connecting member 22 may abut against the inner bottom wall of the groove. This embodiment enables the movable part 2 to have the advantage of a high degree of structural compactness, thereby enabling the surgical bionic model assembly 10 to have the advantage of a high degree of structural compactness, that is, the surgical bionic model assembly 10 requires less space, the surgical bionic model assembly 10 is easy to be received and stored, and the user experience is better.

[0096] In other embodiments (not shown in the figures), the connection structure between the first base 21 and the base 1 may include a rotating structure and / or a sliding structure.

[0097] In other embodiments (not shown in the figures), the first connecting member 22 may be detachably connected to the second structural member 32 of the model 3 to be operated.

[0098] Optionally, see Figure 3a , Figure 3b and Figure 3c As shown, the first connecting member 22 includes a first rotating member 221 and a second rotating member 222. The first base 21 is rotatably connected to the first rotating member 221, the first rotating member 221 is rotatably connected to the second rotating member 222, and the second rotating member 222 is rotatably connected to the first base 21. Figure 1 The first structural member 31 of the model to be operated 3 is shown to be detachably connected.

[0099] Please refer to Figure 3a , Figure 3b and Figure 3c As shown, the user can make the first base 21 and the first rotating member 221 rotate relative to each other, so that the second rotating member 222 and the model to be operated 3 rotate relative to the first base 21. The user can also make the first rotating member 221 and the second rotating member 222 rotate relative to each other, so that the model to be operated rotates relative to the first rotating member 221. Therefore, the internal structure of the movable member 2 of this embodiment includes two rotational degrees of freedom, and the adjustable range of the model to be operated 3 relative to the base 1 is relatively large, so that the user can perform more accurate surgical training, teaching demonstration or surgical plan planning in a posture that is more in line with the actual surgical posture.

[0100] The first base 21 and the first rotating member 221 can rotate as follows: Figure 3a The rotation axis O1 shown rotates relatively, and the direction of the rotation axis O1 and the numerical value of the rotation angle α about the rotation axis O1 have been described above and will not be repeated here.

[0101] In addition, the first rotating member 221 and the second rotating member 222 can rotate as follows: Figure 3aThe rotation axis O2 shown rotates relative to each other, and the rotation axis O2 is the axis of the first rotating member 221. The rotation axis O2 can be perpendicular to the height direction Z of the surgical bionic model component 10. The first rotating member 221 and the second rotating member 222 can pitch and rotate relative to each other. The numerical range of the rotation angle β of the first rotating member 221 and the second rotating member 222 relative to each other can be within 0° to 180°, and the numerical value of the rotation angle β can specifically be 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170° or 180°.

[0102] In other embodiments (not shown in the figures), the rotation axis O2 may be parallel to the height direction Z of the surgical bionic model component 10 .

[0103] In addition, the first rotating member 221 may be a block-shaped structure, and the bottom of the first rotating member 221 may abut against the top of the first base 21. Alternatively, the bottom of the first rotating member 221 may abut against the inner bottom wall of the groove of the first base 21, and the relevant effects have been described above and will not be repeated here. The top of the first rotating member 221 may be rotatably connected to the rod assembly 2221, or any part of the first rotating member 221 between its own top and its own bottom may be rotatably connected to the rod assembly 2221.

[0104] In other embodiments (not shown in the figures), the second rotating member 222 may be detachably connected to the second structural member 32 of the model 3 to be operated.

[0105] Optionally, see Figure 3a , Figure 3b and Figure 3c As shown, the second rotating member 222 includes a rod assembly 2221 and a second base 2222. The first rotating member 221 is rotatably connected to the rod assembly 2221, the rod assembly 2221 is rotatably connected to the second base 2222, and the second base 2222 is rotatably connected to the first rotating member 221. Figure 1 The first structural member 31 of the model to be operated 3 is shown to be detachably connected.

[0106] Please refer to Figure 3a , Figure 3b and Figure 3cAs shown, the user can make the first rotating member 221 and the rod assembly 2221 rotate relative to each other, thereby rotating the second base 2222 and the model to be operated 3 relative to the first rotating member 221. The user can also make the rod assembly 2221 and the second base 2222 rotate relative to each other, thereby rotating the model to be operated 3 relative to the rod assembly 2221. Therefore, the internal structure of the movable member 2 of this embodiment includes three degrees of rotational freedom, and the adjustable range of the model to be operated 3 relative to the base 1 is relatively large, so that the user can perform more accurate surgical training, teaching demonstration or surgical plan planning in a posture that is more in line with the actual surgical posture.

[0107] The first rotating member 221 and the rod assembly 2221 can rotate as follows: Figure 3a The rotation axis O2 shown rotates, and the direction of the rotation axis O2 and the numerical value of the rotation angle β about the rotation axis O2 have been described above and will not be repeated here.

[0108] In addition, the rod assembly 2221 and the second base 2222 can be arranged around Figure 3a The rotation axis O4 shown in the figure rotates, and the rotation axis O4 is the axis of the second base 2222. The rotation axis O4 and the height direction Z of the surgical bionic model component 10 may have an acute angle or an obtuse angle, or the rotation axis O4 may be parallel to the height direction Z of the surgical bionic model component 10. The rod assembly 2221 and the second base 2222 may deflect and rotate relative to each other. The numerical range of the rotation angle Δ between the rod assembly 2221 and the second base 2222 relative to each other may be within 0° to 360°, and the rotation angle Δ The numerical value can specifically be 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, 190°, 200°, 210°, 220°, 230°, 240°, 250°, 260°, 270°, 280°, 290°, 300°, 310°, 320°, 330°, 340°, 350° or 360°.

[0109] In other embodiments, the rotation axis O4 may be perpendicular to the height direction Z of the surgical bionic model component 10 .

[0110] In addition, one end of the rod assembly 2221 can be rotatably connected to the first rotating member 221, and the other end of the rod assembly 2221 can be rotatably connected to the second base 2222. In other embodiments (not shown in the figure), a portion of the rod assembly 2221 that is not the end portion can be rotatably connected to the first rotating member 221, and another portion of the rod assembly 2221 that is not the end portion can be rotatably connected to the second base 2222. In any embodiment of the rod assembly 2221, the rod member rotatably connected to the first rotating member 221 in the rod assembly 2221 and the rod member rotatably connected to the second base 2222 in the rod assembly 2221 are different rod members.

[0111] In other embodiments (not shown in the figures), the second base 2222 can be detachably connected to the second structural member 32 of the model 3 to be operated.

[0112] Optionally, see Figure 3a , Figure 3b and Figure 3c As shown, the rod assembly 2221 includes a first rod 2221a and a second rod 2221b, the first rotating member 221 is rotatably connected to the first rod 2221a, the first rod 2221a is rotatably connected to the second rod 2221b, and the second rod 2221b is rotatably connected to the second base 2222.

[0113] Please refer to Figure 3a , Figure 3b and Figure 3c As shown, the user can make the first rotating member 221 and the first rod 2221a rotate relative to each other, so that the second rod 2221b, the second base 2222 and the model 3 to be operated rotate relative to the first rotating member 221. The user can also make the first rod 2221a and the second rod 2221b rotate relative to each other, so that the second base 2222 and the model 3 to be operated rotate relative to the first rod 2221a. The user can also make the second rod 2221b and the second base 2222 rotate relative to each other, so that the model 3 to be operated rotates relative to the second rod 2221b. Therefore, the internal structure of the movable member 2 of this embodiment includes four degrees of freedom of rotation, and the adjustable range of the model 3 to be operated relative to the base 1 is large, so that the user can perform more surgical training, teaching demonstration or surgical plan planning in a posture that is more in line with the actual surgical posture. Secondly, since both the first rod 2221a and the second rod 2221b have a set length, in the viewing angle and state shown in FIG3 , if the user rotates the first rod 2221a clockwise and the second rod 2221b counterclockwise, the height of the second base 2222 is increased. Accordingly, the height of the operation model 3 is raised. If the user rotates the first rod 2221a counterclockwise and the second rod 2221b clockwise, the height of the second base 2222 is reduced. Accordingly, the height of the operation model 3 is reduced.

[0114] The first rotating member 221 and the first rod 2221a can rotate as follows: Figure 3a The rotation axis O2 shown rotates, and the direction of the rotation axis O2 and the numerical value of the rotation angle β about the rotation axis O2 have been described above and will not be repeated here.

[0115] In addition, the first rod 2221a and the second rod 2221b may be arranged around Figure 3a The rotation axis O3 shown rotates, and the rotation axis O3 can be perpendicular to the height direction Z of the surgical bionic model component 10. The first rod 2221a and the second rod 2221b can pitch relative to each other. The numerical range of the rotation angle γ of the first rod 2221a and the second rod 2221b relative to each other can be within 0° to 180°, and the numerical value of the rotation angle γ can specifically be 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170° or 180°.

[0116] In addition, one end of the first rod 2221a can be rotatably connected to the first rotating member 221, and the other end of the first rod 2221a can be rotatably connected to the second rod 2221b. Of course, some non-end parts of the first rod 2221a can also be rotatably connected to the first rotating member 221, and another non-end part of the first rod 2221a can also be rotatably connected to the second rod 2221b. Similarly, one end of the second rod 2221b can be rotatably connected to the first rod 2221a, and the other end of the second rod 2221b can be rotatably connected to the second base 2222. Of course, some non-end parts of the second rod 2221b can also be rotatably connected to the first rod 2221a, and another non-end part of the second rod 2221b can also be rotatably connected to the second base 2222.

[0117] In other embodiments (not shown in the figures), the rotation axis O3 may be parallel to the height direction Z of the surgical bionic model component 10 .

[0118] Furthermore, the second rod 2221b and the second base 2222 can be arranged around Figure 3a The rotation axis O4 shown rotates, and the direction of the rotation axis O4 and the value of the rotation angle Δ about the rotation axis O4 have been described above and will not be repeated here. In particular, the direction of the rotation axis O4 is parallel to the length direction of the second rod 2221b.

[0119] In other embodiments (not shown in the figures), the connection structure between the first rod 2221a and the second rod 2221b may be a sliding structure, and the length direction of the first rod 2221a and the length direction of the second rod 2221b may be parallel.

[0120] In other embodiments (not shown in the figures), the number of rods included in the rod assembly 2221 may be three or more.

[0121] In addition, the main structure of the second base 2222 may be a disc-shaped structure, such as a circular disc or an elliptical disc, and the end surface of the second base 2222 may be provided with a connection hole 2222a, and the connection hole 2222a is used for a connection member (not shown in the figure, such as a screw or a pin) connected to the first structural member 31 to pass through, so that the second base 2222 is detachably connected to the first structural member 31. One end surface of the second base 2222 may abut against the second rod 2221b, and the other end surface of the second base 2222 may abut against the first structural member 31.

[0122] In other embodiments (not shown in the figures), the second base 2222 may be provided with a groove, and one end of the second rod 2221b may be connected to the inner bottom wall of the groove of the second base 2222. This embodiment enables the movable part 2 to have the advantage of a high degree of structural compactness. The relevant effects have been described above and will not be repeated here.

[0123] From the above content, it can be known that the height of the model to be operated 3 relative to the base 1 can be adjusted by the user, and the angle (such as the deflection angle or the pitch angle) of the model to be operated 3 relative to the base 1 can be adjusted by the user.

Usually, when the user uses the surgical bionic model assembly 10 for surgical training or teaching demonstration, some waste and sewage are generated, and the waste and sewage will fall into the receiving space 11a enclosed by the receiving groove 11 through the opening 11b, that is, the receiving groove 11 is used to collect waste and sewage, and the possibility of the loading table for carrying the surgical bionic model assembly 10 being contaminated is low, the intensity of the cleaning labor required by the user after using the surgical bionic model assembly 10 is low, and the user's use experience is high.

[0125] Optionally, see Figure 1 As shown, the surgical bionic model component 10 also includes an anti-skid pad 4, which is arranged on the side of the base 1 facing away from the model 3 to be operated. The anti-skid pad 4 is used to contact with the loading table to form static friction between the surgical bionic model component 10 and the loading table, so as to reduce the possibility of the surgical bionic model component 10 sliding freely relative to the loading table when the user uses the surgical bionic model component 10, and the user experience is better.

Among them, the first structural member 31 includes a head model 311, and the second structural member 32 includes a nose model 321. This setting is convenient for the user to replace only the nose model 321 after the simulated nasal surgery training, without replacing the head model 311, and the head model 311 can be reused, that is, the model to be operated 3 of this embodiment has the effect of less waste of resources. This setting is also convenient for the user to replace the nose model 321 with different pathological conditions (such as tumors, cysts or polyps).

This setting is convenient for the user to replace only the first replacement block 32a or the second replacement block 32b after the simulated nose surgery training, without replacing the entire second structural member 32, and the first replacement block 32a or the second replacement block 32b can be reused, that is, the model 3 to be operated in this embodiment has the effect of less resource waste. This setting is also convenient for the user to replace the first replacement block 32a and the second replacement block 32b with different pathological conditions (such as tumors, cysts or polyps). For example, the first replacement block 32a can have pathological condition one (tumor), and the second replacement block 32b can have pathological condition two (cyst), so as to meet the needs of users to simulate complex nose surgery training.

[0132] In other embodiments (not shown in the drawings), only the first replacement block 32a may include the nose model 321, or only the second replacement block 32b may include the nose model 321.

The maxillary sinus 3213d is arranged in the first replacement block 32a without destroying the internal structure of the nose model 321, which makes it easier for the user to observe the nasal cavity 3212 in the nose model 321. Further, the nose model 321 also includes internal structures such as the superior nasal meatus, the superior turbinate, the middle nasal meatus, the middle turbinate, the inferior nasal meatus, the nasal vestibule, the maxillary sinus opening, the sphenoid sinus opening and the ethmoid sinus opening (not shown in the figure).

In one example, the soft material and the hard material include a resin material and / or a silicone material.
