[0053] Among related technologies, 3D printing anatomy technology offers a strong sense of immersive realism, real-time interactivity, rich and expandable content, and repeatability, trainability, and regenerability. In recent years, it has been widely used in medical education. The application of 3D printing technology in anatomy teaching includes selecting and importing suitable 3D anatomical data sources, reconstructing 3D modules, printing simulated biomaterials, and comparing and analyzing teaching effectiveness. By using 3D printed anatomy learning, students can avoid the difficulties of obtaining and manipulating physical specimens, learn and master anatomical structures through multiple channels, and improve their skills through repeated practice.

Currently, 3D printing is used in human anatomy teaching; however, due to the complexity of the nasal cavity and sinuses, current 3D printed anatomical models cannot accurately reproduce their structures, resulting in poor teaching effectiveness for nasal cavity and sinus anatomy.

[0054] In view of this, this application provides a method and apparatus for processing 3D printed modular anatomical teaching models of the nasal cavity and sinuses. This application acquires real nasal cavity and sinus image data, and then constructs a 3D virtual model based on this data, including virtual models of bony structures, soft tissue structures, neurovascular structures, or the skull base and orbit. Then, it executes the printing process of the 3D printed modular anatomical teaching model based on the 3D virtual model to obtain a 3D printed modular anatomical teaching model with a 1:1 scale to the real nasal cavity and sinus image data. Nasal cavity and sinus anatomy teaching is then conducted based on this 3D printed modular anatomical teaching model. This allows for the realistic reconstruction of the nasal cavity and sinus structures through the 3D printed modular anatomical teaching model, thereby effectively improving the teaching effect of the 3D printed modular anatomical model of the nasal cavity and sinuses.

[0057] Figure 1 This is an optional flowchart of a method for processing 3D-printed modular anatomical teaching models of the nasal cavity and sinuses provided in the embodiments of this application. Figure 1 The method may include, but is not limited to, steps S110 to S140:

[0058] Step S110: Obtain real nasal cavity and sinus imaging data;

[0059] Step S120: Construct a 3D virtual model based on real nasal cavity and sinus imaging data. The 3D virtual model includes a virtual model of bony structures, a virtual model of soft tissue structures, a virtual model of neurovascular structures, or a virtual model of the skull base and orbit.

[0060] Step S130: Execute the printing process of the 3D printed module anatomical teaching model according to the 3D virtual model to obtain the 3D printed module anatomical teaching model; wherein, the ratio between the size data of the 3D printed module anatomical teaching model and the real nasal cavity and sinus image data is 1:1.

[0061] Step S140: Conduct nasal cavity and sinus anatomy teaching based on the 3D printed module anatomical teaching model.

[0062] In this embodiment, the real nasal cavity and sinus imaging data may include, but is not limited to, real nasal cavity and sinus CT imaging data or real nasal cavity and sinus MR imaging data. This data can be imported into virtual construction software in DICOM file format for three-dimensional virtual model reconstruction. It is understood that after obtaining the aforementioned real image data, the virtual construction software can construct three-dimensional virtual models of the nasal cavity and sinuses based on this data. These virtual models may include, but are not limited to, virtual models of bony structures, virtual models of soft tissue structures, virtual models of neurovascular structures, or virtual models of the skull base and orbit. These virtual models can be viewed individually or assembled from rented models, thereby better displaying the internal structure or adjacent structures of the nasal cavity and sinuses.

[0063] In this embodiment, after obtaining several virtual models of the nasal cavity and sinuses, a 3D-printed modular anatomical teaching model can be printed based on these virtual models. The 3D-printed modular anatomical teaching model is a physical model, and each module within this model is detachable, allowing teachers or students to disassemble or assemble the physical model to effectively understand the structure of the nasal cavity and sinuses. Specifically, the ratio between the data size of each detachable module in the physical model and the actual nasal cavity and sinus image data is 1:1, thereby better reproducing the real structure of the nasal cavity and sinuses. Specifically, the printing process in this embodiment includes, but is not limited to, printing modules based on a bony structure virtual model, printing modules based on a soft tissue structure virtual model, printing modules based on a neurovascular virtual model, and printing modules based on a skull base and orbit virtual model. This embodiment prints each module of the nasal cavity and sinuses separately into 3D solid modules. These independent modules can be used to demonstrate the disassembly, cutting, development, dissection, anatomical operation, and neurovascular anatomy of the nasal cavity and sinuses, thereby effectively improving the teaching effect of anatomical dissection of the 3D printed modules of the nasal cavity and sinuses.

[0064] In this embodiment, nasal cavity and sinus anatomy teaching can be conducted based on an endoscope system, a navigation system, and a 3D-printed modular anatomical teaching model. Specifically, teachers or students can perform anatomical operations on the nasal cavity and sinuses using the 3D-printed modular anatomical teaching model. Then, the endoscope system and navigation system display the path of the operation based on the first data during the operation, allowing for a more intuitive observation of the anatomical results of the nasal cavity and sinuses.

[0065] In this embodiment, the cutting or opening of the nasal cavity and sinuses can also be taught using a brick grinding system and a 3D-printed modular anatomical teaching model. Specifically, teachers or students can perform cutting or opening operations on the nasal cavity and sinuses using the 3D-printed modular anatomical teaching model. The brick grinding system then displays the cutting or opening operations based on second data from the process, allowing teachers or students to observe the process more intuitively.

[0066] Specifically, when conducting teaching demonstrations in 3D printed modular anatomical teaching models, the process of performing anatomical operations related to the nose and eyes, the nasal skull base, and neurovascular structures can be demonstrated. Furthermore, warnings about dangerous operations can be provided during the operation, thereby effectively improving the teaching effect.

[0067] In the embodiments of this application, such as Figure 2 As shown, in this embodiment, when constructing the virtual model, virtual instruments can also be constructed and stored in an instrument library, allowing students to practice virtual anatomy. Furthermore, this embodiment also constructs a nasal cavity and sinus anatomy exercise library, enabling students to obtain third-party data on the target object's testing in the nasal cavity and sinus anatomy exercise library after completing anatomy learning. Based on this third-party data, an assessment result of the target object's nasal cavity and sinus anatomy is generated, allowing the assessment result to determine whether the anatomy learning effect has achieved the expected anatomical goals.

[0068] Therefore, the method of this application embodiment can perfectly reproduce the nasal cavity and its anatomical structure, as well as the adjacent anatomical relationships between the nasal cavity and sinuses and the skull base and orbit. This allows students to learn the anatomical process and relationships of the nasal cavity and sinuses through anatomical models. Simultaneously, this application can also highly reproduce the bone, soft tissue, and vascular and nerve tissue within the nasal cavity, allowing anatomy learners to realistically experience the feel and techniques of dissecting different tissues, thereby improving their clinical surgical skills. Furthermore, this application uses detachable 3D-printed model anatomy for basic training, enabling repeated training from simple to complex, effectively shortening the learning curve and reducing learning difficulty.
