Description

Technical Field

[0001] This utility model relates to the field of medical model technology, and in particular to a modular neural intervention training model. Background Technology

[0002] In the field of medical education and practice, neurointerventional surgery, due to its high degree of specialization and complexity, demands extremely high operational skills from medical personnel. To improve the practical skills of medical staff, training models simulating real surgical environments are particularly important. Traditional neurointerventional surgery training models, as instrument models simulating the human vascular system, are widely used in medical school teaching courses, professional skills training, and continuing education for clinicians. These models can simulate the lesion sites in the human body, helping trainees practice in situations close to real surgical conditions, thereby effectively improving their surgical skills and ability to handle complex lesions.

[0003] However, existing training models for neurointerventional surgery face a significant challenge: the human vascular system, especially the aortic arch region, exhibits extremely high anatomical variability and complex pathological structures. As a crucial component connecting the heart to all major arteries, the aortic arch displays diverse morphologies, including but not limited to normal, bovine, and mirror-image types, and may be accompanied by various lesions such as aneurysms, stenosis, and malformations. Due to the diversity of these variations and pathological structures, traditional training models with single or fixed structures struggle to comprehensively cover all possible teaching scenarios.

[0004] To address this challenge, the current approach is to develop multiple training models targeting different lesion structures to adapt to varying teaching content and training needs. While this approach solves the problem to some extent, it also introduces new issues: on the one hand, the large number of different models leads to a significant waste of resources and increases teaching costs; on the other hand, storing and maintaining these models requires substantial space, placing an additional burden on teaching institutions. Utility Model Content

[0005] To overcome at least one of the shortcomings of the prior art described above, this invention provides a modular neural intervention training model. This solves the problems of redundant resource investment and space occupation.

[0006] The technical solution adopted by this utility model to solve its problem is: A modular neural intervention training model includes: an aortic arch comprising at least two replaceable splicing modules rotatably connected to each other; a head and neck artery module connected to the aortic arch; an upper limb artery module connected to the aortic arch; a lower limb artery module connected to the aortic arch; and an external circulating water pump connected to the aortic arch.

[0007] By adopting the above scheme, the aortic arch is constructed using at least two replaceable splicing modules, which can simulate different vascular structures and lesion types. This design allows the model to flexibly adapt to various teaching or training needs; the model's state can be quickly adjusted simply by replacing the corresponding modules. This solves the problem that traditional models, due to their fixed structure, cannot comprehensively cover all lesion types, thus improving the model's diversity and flexibility. The modular design also makes model maintenance and updates simpler and more efficient. When a module is damaged or needs to be updated, only that module needs to be replaced, without replacing the entire model. Through connection with an external circulating water pump, the model can simulate a real blood circulation system, providing trainees with a training environment that more closely resembles clinical practice.

[0008] Furthermore, the splicing module includes a conventional splicing module and / or a lesion splicing module.

[0009] By adopting the above scheme, the conventional splicing module can be used to simulate normal vascular structures, while the lesion splicing module can be used to simulate various vascular lesions, thereby meeting more diverse teaching and training needs.

[0010] Furthermore, quick-connect joints are provided between the splicing modules.

[0011] By adopting the above solution, the module replacement process is simplified, and the quick-connect splicing connector makes the connection between splicing modules more convenient. Without complicated installation steps, the modules can be quickly replaced, thus improving the efficiency of teaching and training.

[0012] Furthermore, the quick splicing connector includes: a first splicing connector having a first splicing end; a second splicing connector having a second splicing end adapted to the first splicing end; and an unlocking component for controlling the locking and unlocking between the first splicing connector and the second splicing connector.

[0013] By adopting the above scheme, the stability and security of the model are improved. The design of the unlocking component makes the connection between the splicing modules more secure, avoiding unexpected situations caused by loose modules during training. At the same time, the unlocking component is easy to operate, making module replacement simpler and faster.

[0014] Furthermore, the unlocking component is rotatably connected to the second splicing joint. The unlocking component includes an operating end and a locking end. The first splicing end is provided with a locking part that locks with the locking end. When the unlocking component is in the unlocked state, the locking part is separated from the locking end. When the unlocking component is in the locked state, the locking part is engaged with the locking end.

[0015] By adopting the above scheme, the rotating connection unlocking component makes the operation more flexible, while the snap-fit ​​design of the locking part and the locking end ensures a firm connection between modules, improving the stability and reliability of the model.

[0016] Furthermore, a sealing structure is provided between the locking part and the second splice joint.

[0017] By adopting the above solution, model damage or training interruption caused by liquid leakage during training was avoided, ensuring the smooth progress of training.

[0018] Furthermore, at least two unlocking components are provided, and they are equally spaced along the circumference of the quick-connect joint.

[0019] By adopting the above solution, the setting of multiple unlocking components makes the connection between modules more uniform and secure, avoiding the loosening or detachment of modules due to the failure of a single unlocking component.

[0020] Furthermore, the head and neck artery module is provided with a stenotic lesion section, the inner diameter of which is 5%-15% of the inner diameter of the non-stenotic lesion section.

[0021] By adopting the above approach, the design of the stenotic lesion area allows the model to more realistically simulate the lesion of vascular stenosis, providing trainees with a training environment that is closer to clinical practice.

[0022] Furthermore, the head and neck artery module is embedded with a detachable tip embolization lesion module, and / or the head and neck artery module is embedded with a detachable aneurysm lesion module, and / or the head and neck artery module is equipped with a thrombus inlet.

[0023] By adopting the above scheme, the tip embolism lesion module enables the model to simulate vascular embolism, further improving the model's practicality and realism. The detachable aneurysm lesion module allows the model to simulate different types of aneurysm lesions as needed, and also allows for easy replacement or upgrading of the lesion module to adapt to different teaching and training requirements. The thrombus inlet allows for convenient thrombus replenishment.

[0024] Furthermore, the lower limb artery module is equipped with a puncture training module.

[0025] By adopting the above scheme, the puncture training module can provide puncture training, which is conducive to diversified teaching. In summary, the modular neural intervention training model provided by this utility model has the following technical effects: 1. The aortic arch is constructed using interchangeable modular designs, which can simulate different vascular structures and lesion types. This allows the model to flexibly adapt to various teaching or training needs; the model's state can be quickly adjusted simply by replacing the corresponding modules. This solves the problem that traditional models, due to their fixed structure, cannot comprehensively cover all lesion types, allowing trainees to train in conditions closer to real clinical environments. 2. Modular design reduces redundant resource investment. Because the model consists of multiple replaceable modules, it eliminates the need for a complete training model for each specific lesion structure. This design not only reduces teaching costs but also decreases the space required to store and maintain these models, bringing substantial convenience to teaching institutions. 3. Modular design makes model maintenance and updates simpler and more efficient. When a module fails or needs updating, only that module needs to be replaced, without replacing the entire model. This significantly reduces maintenance costs and shortens the time required for model updates; 4. By connecting to an external circulating water pump, this model can simulate a real blood circulation system. This design allows trainees to practice in a training environment that more closely resembles clinical practice, thereby improving their surgical skills and ability to handle complex lesions.

[0028] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0029] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] See Embodiment 1 of this utility model. Figures 1-7As shown, a modular neural intervention training model is disclosed, including an aortic arch 1, a head and neck artery module 2, an upper limb artery module 3, a lower limb artery module 4, and an external circulating water pump (not shown in the figure). In some embodiments, it also includes an experimental platform 40. The aortic arch 1, head and neck artery module 2, upper limb artery module 3, lower limb artery module 4, and external circulating water pump are all fixed on the experimental platform 40. Optionally, the experimental platform 40 can also be replaced with an experimental box or a base, as long as it can support and fix the above structure. The specific fixing method includes, but is not limited to, restraint strap binding or clasp snap-fit. Specifically, in this embodiment 1, the aortic arch 1 includes at least two replaceable splicing modules 11, which are rotatably connected to each other. The head and neck artery module 2 is connected to the aortic arch 1, the upper limb artery module 3 is connected to the aortic arch 1, the lower limb artery module 4 is connected to the aortic arch 1, and the external circulating water pump is connected to the aortic arch 1. By designing at least two replaceable splicing modules 11 to construct the aortic arch 1, these modules can simulate different vascular structures and lesion types. This design allows the model to flexibly adapt to various teaching or training needs. The model state can be quickly adjusted by simply replacing the corresponding modules, solving the problem that traditional models cannot fully cover all lesion types due to their fixed structure, thus improving the diversity and flexibility of the model. The modular design makes model maintenance and updates simpler and more efficient. When a module is damaged or needs to be updated, only that module needs to be replaced, without replacing the entire model. Through the connection with the external circulating water pump, the model can simulate a real blood circulation system, providing trainees with a training environment that is closer to clinical practice.

[0033] Optional, see below Figure 2-4 As shown, the splicing module 11 includes a conventional splicing module 111 and / or a lesion splicing module 112. During normal blood vessel teaching, multiple splicing modules 11 can be spliced ​​into the conventional splicing module 111. When it is necessary to simulate a certain lesion structure, the lesion splicing module 112 corresponding to the structure is assembled with the conventional splicing module 111 to simulate the blood structure of the corresponding lesion.

[0034] In this embodiment 1, three splicing modules 11 are provided, and each splicing module 11 can be a conventional splicing module 111 or a lesion splicing module 112. For details, please refer to [link to documentation]. Figure 2 As shown, all three splicing modules 11 are conventional splicing modules 111, see reference. Figure 3 As shown, all three splicing modules 11 are lesion splicing modules 112, thereby simulating type I / II / III aortic arch type 1, see reference. Figure 4As shown, the three splicing modules 11 are a combination of the conventional splicing module 111 and the lesion splicing module 112. Therefore, according to the type of variation, they can be spliced ​​into various variant model structures such as bull's arch, aberrant right subclavian artery, ectopic left vertebral artery, non-mirror right aortic arch 1 with aberrant left subclavian artery, double brachiocephalic artery, and mirror right aortic arch 1, to meet more diverse teaching and training needs.

[0035] To achieve the above-described splicing structure, in some embodiments, see [reference needed]. Figure 5-7 As shown, quick-connect splicing connectors 5 are provided between the splicing modules 11. By providing quick-connect splicing connectors 5, the module replacement process is simplified. Quick-connect splicing connectors 5 make the connection between splicing modules 11 more convenient, eliminating the need for complex installation steps and enabling rapid module replacement, thus improving teaching and training efficiency. In this embodiment 1, the quick-connect splicing connector 5 includes a first splicing connector 6, a second splicing connector 7, and an unlocking component 8. The unlocking component 8 is used to control the locking and unlocking between the first splicing connector 6 and the second splicing connector 7. The first splicing connector 6 has a first splicing end 61 and a first connecting end 62. The second splicing connector 7 has a second splicing end 71 and a second connecting end 72 that are adapted to the first splicing end 61. One end of each splicing module 11 is assembled and connected to the first connecting end 62, and the other end is assembled and connected to the second connecting end 72. Optionally, the splicing module 11 and the quick-connect splicing connector 5 are sealed together, including but not limited to integral connection, threaded connection, or snap-fit ​​connection. In this embodiment 1, the splicing module 11 and the quick-connect splicing connector 5 are threaded sealed together. The design of the unlocking component 8 improves the stability and safety of the model, making the connection between the splicing modules 11 more secure and avoiding accidents caused by loose modules during training. At the same time, the unlocking component 8 is easy to operate, making module replacement simpler and faster.

[0036] To better achieve the stability and convenience of splicing the first splicing joint 6 and the second splicing joint 7, the unlocking component 8 is rotatably connected to the second splicing joint 7. The unlocking component 8 includes an operating end 81 and a locking end 82. The first splicing end 61 is provided with a locking part 611 that locks with the locking end 82. When the unlocking component 8 is in the unlocked state, the locking part 611 is separated from the locking end 82. When the unlocking component 8 is in the locked state, the locking part 611 is engaged with the locking end 82. The rotatably connected unlocking component 8 makes the operation more flexible, and the engaging design of the locking part 611 and the locking end 82 ensures a firm connection between the modules, improving the stability and reliability of the model. Specifically, in this embodiment 1, the operating end 81 is a lever or handle that is easy for the user to manually operate, the locking end 82 is provided with a snap-fit ​​groove, and the locking part 611 of the first splicing end 61 is a snap-fit ​​flange that can snap with the snap-fit ​​groove. The end of the snap-fit ​​flange facing the second splicing joint 7 is provided with a curved surface. When the snap-fit ​​flange is inserted towards the second splicing joint 7, the unlocking member 8 can be inserted smoothly regardless of its state. After insertion, the unlocking member 8 is rotated by operating the operating part of the unlocking member 8. At this time, the snap-fit ​​groove of the locking end 82 of the unlocking member 8 faces the snap-fit ​​flange. At this time, the first splicing joint 6 and the second splicing joint 7 achieve a splicing effect and cannot be separated. When there is liquid flowing inside, the pressure is released in the direction away from the first splicing joint 6 and the second splicing joint 7. At this time, the snap-fit ​​groove and the snap-fit ​​flange snap more tightly, making the unlocking member 8 more secure.

[0037] In some embodiments, to improve the sealing between the first joint 6 and the second joint 7, a sealing structure 9 is provided between the locking part 611 and the second joint 7. Preferably, the sealing structure 9 is a sealing ring or a sealing gasket, which can effectively prevent model damage or training interruption caused by liquid leakage during training, ensuring smooth training progress.

[0038] It should be noted that at least two unlocking components 8 are provided, and they are evenly spaced along the circumference of the quick-connect joint 5. The arrangement of multiple unlocking components 8 makes the connection between modules more uniform and secure, avoiding module loosening or detachment due to the failure of a single unlocking component 8. In this embodiment 1, two unlocking components 8 are provided, and they are symmetrically arranged, which facilitates convenient operation with the thumb and forefinger.

[0039] In some embodiments, optionally, the head and neck artery module 2 is provided with a stenosis lesion section 10, the inner diameter of which is 5%-15% of the inner diameter of the non-stenosis lesion section 10. The stenosis lesion section 10 allows the model to more realistically simulate the lesion of vascular stenosis, providing trainees with a training environment closer to clinical reality. Specifically, the stenosis lesion section 10 can also be a detachable locally narrowed tube, or a compression band can be applied to the corresponding blood vessel to achieve different unspecified lesion effects by changing the local narrowing. Specifically, the stenosis lesion section 10 includes, but is not limited to, stenosis of the initial segment of the internal carotid artery, stenosis of the communicating segment, stenosis of the middle cerebral artery, stenosis of the vertebral artery ostium, stenosis of the V4 segment of the vertebral artery, or stenosis of the mid-segment of the basilar artery.

[0040] In some embodiments, optionally, the head and neck artery module 2 may embed a detachable tip embolism lesion module 20. The tip embolism lesion module 20 includes, but is not limited to, embolism of the internal carotid artery communicating segment, embolism of the M1 segment of the middle cerebral artery, embolism of the M2 segment of the middle cerebral artery, and embolism of the basilar artery tip. This allows the model to simulate vascular embolism, further improving the model's practicality and realism.

[0041] In some embodiments, optionally, the head and neck artery module 2 embeds a detachable aneurysm lesion module 30. The aneurysm lesion module 30 includes, but is not limited to, internal carotid artery C4-7 aneurysms, anterior communicating artery aneurysms, posterior communicating artery aneurysms, M1 segment aneurysms in the middle cerebral artery, V4 segment aneurysms in the vertebral artery, and basilar artery segment aneurysms. This allows the model to simulate different types of aneurysm lesions as needed, and also allows for easy replacement or upgrading of the lesion module to adapt to different teaching and training requirements.

[0042] In some embodiments, optionally, the head and neck artery module 2 is further provided with a thrombus inlet 50, which facilitates the replenishment of thrombi within the model. Optionally, the lower limb artery module 4 is provided with a puncture training module 60 to simulate real human tissue, allowing trainees to practice puncture techniques without harming real patients. Of course, in other embodiments, the puncture training module 60 may also be located in the upper limb artery module 3 or other modules; this embodiment does not impose specific limitations.

[0043] It should be noted that the disassembly structure between the head and neck artery module 2, the stenotic lesion section 10, and the tip embolism lesion module 20 can use a quick splicing connector 5 or other splicing methods. This embodiment does not make specific limitations. Similarly, in other embodiments, the quick splicing connector 5 structure between the splicing modules 11 can also be changed according to actual needs, as long as the above splicing effect can be achieved. This embodiment does not make specific limitations.

[0044] In summary, the modular neural intervention training model provided by this utility model has the following technical effects: 1. The aortic arch 1 is constructed using interchangeable splicing modules 11, which can simulate different vascular structures and lesion types. This allows the model to flexibly adapt to various teaching or training needs; the model's state can be quickly adjusted simply by replacing the corresponding modules. This solves the problem that traditional models, due to their fixed structure, cannot fully cover all lesion types, allowing trainees to train in conditions closer to real clinical environments. 2. Modular design reduces redundant resource investment. Because the model consists of multiple replaceable modules, it eliminates the need for a complete training model for each specific lesion structure. This design not only reduces teaching costs but also decreases the space required to store and maintain these models, bringing substantial convenience to teaching institutions. 3. Modular design makes model maintenance and updates simpler and more efficient. When a module fails or needs updating, only that module needs to be replaced, without replacing the entire model. This significantly reduces maintenance costs and shortens the time required for model updates; 4. By connecting to an external circulating water pump, this model can simulate a real blood circulation system. This design allows trainees to practice in a training environment that more closely resembles clinical practice, thereby improving their surgical skills and ability to handle complex lesions.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
