[0057] Figure 1 is an optional flow chart of a method for processing a 3D printed module anatomical teaching model of the nasal cavity and paranasal sinuses provided in an embodiment of the present application, Figure 1 The method may include but is not limited to steps S110 to S140:

[0058] Step S110, obtaining real nasal cavity and paranasal sinus image data;

[0059] Step S120: construct a 3D virtual model based on the real nasal cavity and paranasal sinus image data, wherein the 3D virtual model includes a bony structure virtual model, a soft tissue structure virtual model, a neurovascular virtual model, or a skull base and orbital virtual model.

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

[0061] Step S140: conducting nasal cavity and paranasal sinus anatomy teaching according to the 3D printed module anatomy teaching model.

[0062] In an embodiment of the present application, the real nasal cavity and paranasal sinus image data may include but are not limited to real nasal cavity and paranasal sinus CT image data or real nasal cavity and paranasal sinus MR image data. These data can be imported into the virtual construction software in the form of DI COM file format for three-dimensional virtual model reconstruction. It is understandable that after obtaining the above-mentioned real image data, the virtual construction software can construct a three-dimensional virtual model of the nasal cavity and paranasal sinuses based on these data. These virtual models may include but are not limited to a virtual model of bony structure, a virtual model of soft tissue structure, a virtual model of nerves and blood vessels, or a virtual model of skull base and orbit. These virtual models can be viewed individually or assembled and viewed together, so as to better display the internal structure or adjacent structures of the nasal cavity and paranasal sinuses.

[0063] In an embodiment of the present application, after obtaining several virtual models of the nasal cavity and paranasal sinuses, the printing process of the 3D printing module anatomical teaching model can be performed based on these virtual models. Among them, the 3D printing module anatomical teaching model is a physical model, and each module in the model is a detachable module, so that teachers or students can disassemble or assemble the physical model, and then effectively understand the structure of the nasal cavity and paranasal sinuses. Specifically, the data size data of each detachable module in the physical model and the real nasal cavity and paranasal sinus image data are in a ratio of 1:1, so that the real structure of the nasal cavity and paranasal sinuses can be better restored. Specifically, the printing process of this embodiment includes but is not limited to executing the printing process of the bony structure module according to the bony structure virtual model, executing the printing process of the soft tissue structure module according to the soft tissue structure virtual model, executing the printing process of the neurovascular module according to the neurovascular virtual model, and executing the printing process of the skull base and orbital module according to the skull base and orbital virtual model. In this embodiment, after each module of the nasal cavity and paranasal sinuses is printed separately into a 3D solid module, these independent modules can be used to perform nasal cavity and paranasal sinus splitting demonstration, cutting demonstration, development operation demonstration, dissection demonstration, nasal skull base related dissection demonstration, neurovascular dissection operation demonstration, etc., so as to effectively improve the 3D printing module anatomy teaching effect of the nasal cavity and paranasal sinuses.

[0064] In the embodiment of the present application, the nasal cavity and paranasal sinus anatomical positioning teaching can be carried out based on the endoscope system, the navigation system and the 3D printing module anatomical teaching model. Specifically, the teacher or student can perform the nasal cavity and paranasal sinus anatomical operation in the 3D printing module anatomical teaching model, and then display the path of the operation process based on the first data in the operation process through the endoscope system and the navigation system, so as to observe the nasal cavity and paranasal sinus anatomical effect more intuitively.

[0065] In the embodiment of the present application, the cutting or opening operation teaching of the nasal cavity and paranasal sinuses can also be carried out based on the grinding brick system and the 3D printing module anatomical teaching model. Specifically, the teacher or student can perform the cutting or opening operation of the nasal cavity and paranasal sinuses in the 3D printing module anatomical teaching model, and then display the cutting or opening operation of the nasal cavity and paranasal sinuses based on the second data in the operation process through the grinding brick system, so that the teacher or student can observe the process of the cutting or opening operation of the nasal cavity and paranasal sinuses more intuitively.

[0066] Specifically, when conducting teaching demonstrations in the 3D printed module anatomical teaching model, the process of nose-eye related anatomy, nasal skull base related anatomy, and neurovascular anatomy operations can also be demonstrated, and dangerous operation prompts can be given during the operation, thereby effectively improving the teaching effect.

[0067] In the embodiments of the present application, Figure 2 As shown, when constructing a virtual model, the embodiment of the present application can also construct a virtual instrument, and save the constructed virtual instrument in the instrument library, so that students can perform virtual anatomical exercises. In addition, the embodiment of the present application also constructs a nasal cavity and paranasal sinus anatomy question bank, so that after completing the anatomical learning, students can obtain the third data of the target object tested in the nasal cavity and paranasal sinus anatomy question bank, and generate the evaluation results of the nasal cavity and paranasal sinus anatomy corresponding to the target object according to the third data, and then judge whether the anatomical learning effect reaches the expected anatomical goal through the evaluation results.

[0068] It can be seen that the method of the embodiment of the present application can perfectly restore the anatomical structure of the nasal cavity and the nasal cavity, and restore the adjacent anatomical relationship between the nasal cavity and the paranasal sinuses and the skull base and the eye sockets, so that students can learn the anatomical process and adjacent relationship of the nasal cavity and paranasal sinuses through the study of anatomical models. At the same time, the present application can also highly restore the bone tissue, soft tissue and vascular nerve tissue in the nasal cavity, so that the anatomical learners can truly feel the feel and anatomical techniques of dissecting different tissues, thereby improving the learners' clinical surgical skills. In addition, the present application uses detachable 3D printed model dissection for basic training, so that repeated training can be carried out from the shallow to the deep, so as to effectively shorten the learning curve and learning difficulty.
