Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sinus teaching device. Background Technology

[0002] Otolaryngological surgery is based on an understanding of the anatomy of the ear, nose and throat, but otolaryngology involves complex anatomy, especially the anatomy of the sinuses.

[0003] Sinus surgery requires a three-dimensional understanding of the anatomical structure. The complex anatomical relationships and drainage processes of the sinuses often lead to a lack of mastery of anatomical structures among undergraduates and even graduate students undergoing residency training. To further their studies, anatomical specimens are often required. To enhance students' understanding of organ structures, organ models are typically used for learning. However, existing models usually represent a single, holistic structure, while different diseases manifest differently at different locations on the organ. Therefore, the holistic model structure usually represents only one disease. To comprehensively learn about the normal state and various disease-related states, many different models usually need to be purchased, which not only takes up storage space but also makes management difficult due to the large number of models, increasing the cost and time of procurement and management.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a sinus teaching device, which aims to solve the problem of needing to purchase a large number of sinus models in order to learn about the normal state of the sinuses and various diseased states, thereby reducing the storage space occupied, reducing procurement and management costs, and improving the learning efficiency of medical students about the sinuses.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: A sinus teaching device, comprising:

[0007] The main mounting base includes a model of a unilateral nasal cavity and sinuses, and the model is provided with several accommodating cavities.

[0008] A dissecting mount, which is detachably mounted on the receiving cavity.

[0009] Furthermore, a first mounting member is provided within the receiving cavity, and a second mounting member is provided within the anatomical mounting member. The first mounting member and the second mounting member are matched to install the anatomical mounting member within the receiving cavity.

[0010] Furthermore, a first identifier is provided in the receiving cavity, and a second identifier is provided in the anatomical installation component, so that the corresponding anatomical installation component is installed in the receiving cavity according to the first identifier and the second identifier.

[0011] Furthermore, a limiting groove is provided within the receiving cavity to match the corresponding anatomical mounting component.

[0012] Furthermore, the anatomical mounting component is provided with a limiting block to match the corresponding receiving cavity.

[0013] Furthermore, the main body mounting base is provided with a first fixing groove, and the rotating fixing rod is rotatably mounted on the main body mounting base;

[0014] The anatomical mounting component is provided with a second fixing groove so that when the anatomical mounting component is installed in the receiving cavity, the second fixing groove engages with the first fixing groove;

[0015] The end of the rotating fixing rod is provided with a fixing protrusion, which is slidably installed in the first fixing groove or the second fixing groove.

[0016] Furthermore, the anatomical mounting device is also equipped with an auxiliary rod.

[0017] Furthermore, the main mounting base also includes a support rod and a base, the support rod being vertically mounted on the base, and the receiving cavity being mounted on the end of the support rod away from the base.

[0018] Furthermore, the sinus teaching device also includes a guide for guiding the anatomical mounting component to be installed on the main mounting base.

[0019] Furthermore, the guide includes a display, which is electrically connected to the main mounting base.

[0020] Beneficial effects:

[0021] This application provides a sinus teaching device designed to address the problem of sinus specimens not being reusable, which hinders medical students' learning and surgical practice of sinuses, thereby improving their learning efficiency. The device comprises several cavities within a single-sided nasal cavity and sinus model on the main mounting base. Each cavity contains multiple anatomical mounting components, which can be selectively installed in their respective cavities to create pathological model combinations representing different disease states.

[0032] This utility model provides a sinus teaching device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit this utility model.

[0033] like Figures 1 to 5As shown, a sinus teaching device aims to address the problem that sinus specimens cannot be reused repeatedly, affecting medical students' learning and surgical procedures on sinuses. It includes a main mounting base 1 and an anatomical mounting component 2. The main mounting base 1 includes a model of a unilateral nasal cavity and sinuses, with a receiving cavity 11 within it. Specifically, the receiving cavity 11 contains various structures of the fixed portion of the unilateral nasal cavity and sinuses, such as the orbit, frontal sinus, maxillary sinus, and sphenoid sinus. These structures are arranged in a specific pattern within the receiving cavity 11, with the arrangement of these structures referencing existing sinus models. The anatomical mounting component 2 is detachably mounted on the receiving cavity 11. The anatomical mounting component 2 includes structures of the nasal cavity and sinuses excluding the fixed portions, such as the uncinate process, ethmoid bulla, middle turbinate, inferior turbinate, superior turbinate, and ethmoid air cells. Additionally, 5-10 ethmoid air cells are provided as needed. It also includes structures of abnormal nasal cavity and sinuses, such as the bullous middle turbinate and the reversed middle turbinate, to facilitate further analysis of the nasal cavity and sinuses using these structures. Each cavity 11 is equipped with multiple anatomical mounting pieces 2. These pieces are selectively installed within their respective cavities to create different combinations of pathological models representing various disease states. In other words, the sinus teaching device can create different states when different anatomical mounting pieces 2 are installed within the cavity 11. For example, when an anatomical mounting piece 2 representing the structures of a normal sinus or nasal cavity is installed in the cavity 11, the device displays a normal sinus or nasal cavity state. Conversely, when an anatomical mounting piece 2 representing the structures of an abnormal sinus or nasal cavity is installed, the device displays an abnormal sinus or nasal cavity state. This allows the device to demonstrate sinus and nasal cavities exhibiting different pathological abnormalities by installing anatomical mounting pieces 2 representing different pathological abnormalities. Furthermore, the sinus teaching device of this application can guide learners in studying the corresponding sinus and nasal cavity structures, ultimately providing them with a comprehensive understanding of the sinus and nasal cavity. This enables learners to perform actual sinus surgery and enhance their understanding of the states of various structures within the sinus and nasal cavity when pathological abnormalities occur.

[0034] In order to facilitate the installation of the dissecting mounting component 2 within the receiving cavity 11, or to facilitate its removal from the receiving cavity 11, a first mounting component 111 is provided within the receiving cavity 11. Correspondingly, the dissecting mounting component 2 is provided with a second mounting component 21. Therefore, by matching the first mounting component 111 and the second mounting component 21, the dissecting mounting component 2 can be smoothly installed within the receiving cavity 11. In order to facilitate the removal of the dissecting mounting component 2 from the receiving cavity 11, both the first mounting component 111 and the second mounting component 21 are magnetically attracted. That is, when the dissecting mounting component 2 is installed within the receiving cavity 11, the first mounting component 111 and the second mounting component 21 gradually attract each other until they adhere to each other, thus completing the installation of the dissecting mounting component 2. When it is necessary to remove the dissecting mounting component 2 from the receiving cavity 11, a certain force is applied to the dissecting mounting component 2, causing the second mounting component 21 to separate from the first mounting component 111, thus completing the removal of the dissecting mounting component 2.

[0035] Furthermore, different anatomical mounting parts 2 need to be installed on specific receiving cavities 11 to avoid damage to the sinus teaching device in this application when the anatomical mounting parts 2 do not match the receiving cavity 11, and also to further emphasize the cooperation relationship between different structures in the sinuses. Therefore, a first identifier 112 is provided in the receiving cavity 11, and a second identifier 22 is provided in the anatomical installation component 2. The corresponding anatomical installation component 2 is installed in the receiving cavity 11 according to the first identifier 112 and the second identifier 22. Only when the first identifier 112 and the second identifier 22 match can the specified anatomical installation component 2 be installed in the corresponding receiving cavity 11. Specifically, in this application, the first identifier 112 and the second identifier 22 are numerical codes. The numerical codes of the corresponding anatomical installation component 2 and the receiving cavity 11 are the same or correspond to each other. Therefore, before installing the specified anatomical installation component 2 in the corresponding receiving cavity 11, the numerical code on the second identifier 22 on the anatomical installation component 2 is checked first, and then the numerical code on the first identifier 112 on the receiving cavity 11 is checked. When the numerical codes on the first identifier 112 and the second identifier 22 match, the anatomical installation component 2 can be installed in the receiving cavity 11, ensuring that the anatomical installation component 2 is installed in the accurate receiving cavity 11, and deepening the learner's memory of the relative relationships of the various structures in the sinuses. At this point, the learner performs a side segment based on the existing numerical codes. If the numerical codes match, the installation is correct; if they do not match, the installation is incorrect. The device can also determine whether the sinus teaching device represents a normal sinus or nasal cavity or a sinus or nasal cavity with a specific lesion based on the matching numerical codes, thereby further promoting the learner's understanding of the sinus and nasal cavity.

[0036] When installing the anatomical installer 2 into the receiving cavity 11, to ensure a more secure and stable installation of the matching anatomical installer 2 and the receiving cavity 11, and to prevent the installation of mismatched anatomical installers 2 into the receiving cavity 11, a limiting groove 113 is provided within the receiving cavity 11. The limiting groove 113 restricts the installation of only anatomical installers 2 with specific structures into that receiving cavity 11. Therefore, a limiting block 23 is also provided on the anatomical installer, which matches the limiting groove 113. This allows specific anatomical installers 2 to be installed into their corresponding receiving cavities 11, preventing mismatched anatomical installers 2 from being installed into the receiving cavity 11, and guiding learners to recognize the correct relative relationships between different structures within the sinuses.

[0037] In addition, to ensure the anatomical installer 2 is securely installed within the receiving cavity 11 and to prevent it from falling out, maintaining its stability within the cavity 11, the stability of the anatomical installer 2 is maintained by the cooperation of the rotating fixing rod 14 with the first fixing groove 15 and the second fixing groove 25. Specifically, the rotating fixing rod 14 is rotatably mounted on the main mounting base 1, which also has a first fixing groove 15 in an arc shape. The anatomical installer 2 has a second fixing groove 25. When the anatomical installer 2 is installed within the receiving cavity 11, the first fixing groove 15 and the second fixing groove 25 engage. Therefore, whether the anatomical installer 2 is installed correctly within the receiving cavity 11 can be determined by whether the first fixing groove 15 and the second fixing groove 25 engage and match when installed. Only when the first fixing groove 15 and the second fixing groove 25 engage and match is the anatomical installer 2 correctly installed. Furthermore, in order to fix the anatomical installer 2 within the receiving cavity 11, a fixing protrusion (not shown in the figure) is provided at the end of the rotating fixing rod 14. The fixing protrusion is located on the side of the rotating fixing rod 14 facing the receiving cavity 11. The fixing protrusion is slidably installed in the first fixing groove 15 or the second fixing groove 25. Initially, the fixing protrusion is located in the first fixing groove 15. Only when it is necessary to fix the anatomical installer 2 is the fixing protrusion slid along the first fixing groove 15 to the second fixing groove 25 by rotating the rotating fixing rod 14, so that the fixing protrusion stays in the second fixing groove 25. The anatomical installer 2 is fixed by being held between the fixing protrusion and the receiving cavity 11, thus preventing the anatomical installer 2 from falling out. Therefore, when the anatomical installer 2 is installed in the receiving cavity 11, in order to fix the anatomical installer 2 within the receiving cavity 11, the rotating fixing rod 14 is rotated to slide the fixing protrusion from the first fixing groove 15 to the second fixing groove 25, as shown below. Figure 1 and Figure 2As shown, the anatomical mounting piece 2 is fixed in place; when it is necessary to remove the anatomical mounting piece 2 from the receiving cavity 11, the rotating fixing rod 14 is rotated in the opposite direction, so that the fixing protrusion slides from the second fixing groove 25 to the first fixing groove 15, thereby releasing the fixation of the anatomical mounting piece 2, and the anatomical mounting piece 2 can be smoothly removed from the receiving cavity 11.

[0038] Furthermore, to facilitate the installation of the anatomical installer 2 within the receiving cavity 11, the anatomical installer 2 is also equipped with an auxiliary rod 26. The auxiliary rod 26 is positioned on the side of the anatomical installer 2 facing away from the receiving cavity 11. This ensures that the anatomical installer 2 can be installed in the correct receiving cavity 11, where its shape perfectly matches the cavity 11. Without this auxiliary structure, installation of the anatomical installer 2 might be difficult, preventing its placement within the cavity 11. With the auxiliary rod 26, the learner can avoid contact with the receiving cavity 11 while attempting to install the anatomical installer 2, preventing the installer 2 from being unable to fit. Similarly, when removing the anatomical installer 2, the learner can simply grasp the auxiliary rod 26 and rotate the fixing rod 14 to disengage the fixing protrusion from the second fixing groove 25, then pull the anatomical installer directly out of the receiving cavity 11. Therefore, the auxiliary rod 26 facilitates the installation and removal of the anatomical installer 2.

[0039] In addition, the main mounting base 1 also includes a support rod 12 and a base 13. The support rod 12 is vertically mounted on the base 13, and the receiving cavity 11 is mounted on the end of the support rod 12 away from the base 13. The base 13 and the support rod 12 support the receiving cavity 11, so that the receiving cavity 11 can be placed stably and avoid the receiving cavity 11 shaking and affecting its use.

[0040] In addition to allowing learners to determine whether the anatomical mounting component 2 is correctly installed in the receiving cavity based on the numerical code, this application also includes a guide component 3, which guides the anatomical mounting component 2 to be installed on the main mounting base 1. This allows learners to fully understand the various structures and their arrangement of the sinuses through the sinus teaching device of this application, ultimately enabling them to perform sinus surgery in practice.

[0041] The guide 3 is specifically a display screen, which is electrically connected to the main mounting base 1. The display screen shows whether the corresponding anatomical installer 2 is installed in each receiving cavity 11 within the main mounting base 1, and displays the structure corresponding to the anatomical installer 2 installed in the receiving cavity 11. The display screen can also be used for teaching learners. Specifically, during teaching, the display screen will display a patient's information and medical history, along with CT images of the sinuses. The CT images include both normal and abnormal images. Learners need to select the correct anatomical installer 2 based on the CT images and install it in the receiving cavity 11. They also need to collect the digital code on the first identifier 112 of the anatomical installer 2 and the digital code on the second identifier 22 within the receiving cavity 11. After inputting the collected codes on the display screen, they can complete the exercise related to that patient, receive prompts for the next step, and then proceed to the next exercise.

[0042] To enable real-time feedback from the display, determining which anatomical installers 2 have been installed on the receiving cavity 11 and whether the installation of the anatomical installers 2 has been completed correctly, a first data port 114 is provided in the receiving cavity 11, and a second data port 24 is provided for each anatomical installer 2. When the anatomical installer 2 is installed in the receiving cavity 11, the first data port 114 and the second data port 24 are connected. Once the first data port 114 and the second data port 24 are connected, the display can indicate that a specific anatomical installer 2 has been installed. When the anatomical installer 2 is installed, the display shows one status; when the anatomical installer 2 is not installed, the display shows another status. The status of the guide 3 is used to determine whether the anatomical installer 2 is installed in the receiving cavity 11. The display can also be further configured. For example, after the installation of a certain anatomical installer 2 is completed, a digital code input window pops up on the display. Only after correctly entering the digital code of the anatomical installer 2 and the corresponding receiving cavity 11 will the display display prompt the corresponding structural information and allow the next step, thereby further enhancing the learner's impression of the sinuses and nasal cavity.

[0043] In summary, when using the sinus teaching device for teaching, the first marker 112 and the second marker 22 guide learners to install specific anatomical installation pieces 2 into the corresponding receiving cavities 11. The limiting groove 113 and the limiting block 23 further restrict the installation of the anatomical installation pieces 2 into the corresponding receiving cavities 11 until all receiving cavities 11 are equipped with the corresponding anatomical installation pieces 2. This strengthens learners' memory and understanding of the relative relationships of various structures within the sinuses. At the same time, since the entire teaching process is similar to a puzzle-solving adventure, the teaching process is also more interesting, thereby improving the efficiency of learners' learning of sinus structures.

[0044] In addition, the installation of the anatomical installation component 2 can be completed by the guidance of the guide component 3. When the installation of each anatomical installation component 2 is completed, the guide component 3 will give the corresponding instructions. After all the anatomical installation components 2 that need to be installed in the receiving cavity 11 are accurately installed and the corresponding codes are entered in the display, one exercise ends and the next step is taken. This is how the anatomical installation components 2 are installed in the receiving cavity 11.

[0045] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
