[0081] Through the above steps, you can systematically develop a professional brain abscess simulator for use in clinical teaching to improve the practical operation ability of medical students and doctors.
[0082] Please refer to Figure 1 ,The process of making the simulation head model includes:
[0083] S1, obtaining medical image data, and constructing a 3D brain model using 3D modeling software and the medical image data.
[0084] In specific implementation, step S1 includes:
[0085] (1) Brain structure scan
[0086] Using high-resolution medical imaging data (such as MRI, CT scans) as a basis, the detailed morphology of the brain and related tissues is extracted. The imaging data can be imported into 3D modeling software in DICOM format. The 3D modeling software can be Blender, Maya, 3ds Max, etc.
[0087] (2) Hierarchical Modeling
[0088] The brain is broken down into multiple anatomical layers, such as cortex, white matter, ventricles, blood vessels, nerve fibers, etc. Each layer needs to accurately reflect its shape, size, position and relationship with each other.
[0089] (3) Texture and material assignment
[0090] Using actual medical images as reference, the 3D model of the brain is given realistic textures and colors to enhance the visual effect. Different tissues (such as gray matter, white matter, and blood vessels) can be given different physical properties, such as hardness and elasticity, for subsequent physical simulation.
[0091] (4) Abscess simulation:
[0092] The process of simulating brain abscess requires dynamic modeling of brain tissue. Use deformation tools to simulate the abscess process, which is manifested as volume increase and morphological deformation. Ensure that the simulation process can reflect actual physiological changes, such as pressure changes caused by obstruction of cerebrospinal fluid flow, displacement and squeezing of tissues, etc.
[0093] S2, using 3D printing technology to print a 3D model of the brain to obtain a simulated head model.
[0094] In specific implementation, step S2 includes:
[0095] (1) Material selection
[0096] If you need to build a physical model, choosing the right material is critical. Soft, deformable materials such as silicone are often used to simulate brain tissue. For parts that need to simulate bones or hard structures, you can choose harder materials such as plastic or polyurethane.
[0097] (2) 3D printing
[0098] 3D printing technology can quickly generate accurate physical models. Choose the right printer and material to ensure that the details and texture of the model can meet teaching needs.
[0099] It should be noted that the model obtained by 3D printing can be called a physical model. When simulation is used for brain abscess simulation, a deformable model may be required to simulate processes such as abscess, contraction and pressure conduction. In this case, air bags or liquid fillers can be used to achieve dynamic simulation. When the pressure increases, the model will expand to simulate the effect of brain abscess.
[0100] It should be noted that before the above-mentioned brain 3D model is 3D printed, dynamic simulation, model verification and optimization, model output and integration and other operations can be performed on the computer, as follows:
[0101] (1) Dynamic simulation
[0102] Physics engine integration: Import the 3D model into a physics engine (such as Unity, Unreal Engine) to achieve real-time physiological simulation. Through program control, the model can automatically change abscesses, displacements, etc. according to preset physiological parameters (such as intracranial pressure, cerebrospinal fluid flow).
[0103] Interactive design: Design an interactive interface that users can operate, such as simulating drainage and decompression processes through the operation of surgical tools. Through tactile feedback devices, users can feel the force during surgery, enhancing the authenticity of the simulation.
[0104] Real-time feedback and adjustment: The simulator should be able to provide real-time feedback on the results of the operation, such as pressure changes, abscess reduction or aggravation, etc. Through dynamic adjustment, different clinical scenarios can be simulated, such as the effects of different degrees of abscess or pressure changes on tissues.
[0105] (2) Model verification and optimization
[0106] Accuracy verification: Compare the 3D model and physical simulation results with actual case data to verify the accuracy of the model. Clinicians can be invited to conduct verification to ensure that the simulator can truly reflect the actual clinical situation.
[0107] Optimize modeling: Based on test results and user feedback, optimize the model's details, materials, and dynamic performance to ensure that the simulator can run stably under different operating conditions.
[0108] (3) Model output and integration
[0109] Model output: The final 3D model and dynamic simulation program are output as executable files and integrated into the overall system of the simulator. Files in multiple formats can be generated as needed to adapt to different platforms and hardware devices.
[0110] Integration and deployment: Integrate the modeling results with other system modules (such as user interface, data logging) to form a complete simulator system. Deploy to the target device (such as VR helmet, haptic feedback device) for final system testing and debugging.
[0111] Please refer to Figure 2 and Figure 3 The highly simulated brain abscess teaching simulator provided by the embodiment of the present invention comprises a simulated head model, a brain abscess simulation module, a brain abscess control module, an intracranial pressure monitoring module and a surgery simulation module. The brain abscess simulation module and the intracranial pressure monitoring module are connected to an external display or a VR system.
[0112] Among them, the simulation head model includes:
[0113] Scalp and skull simulation part: The exterior of the simulation head model is made of highly simulated silicone or polymer materials to simulate the texture and elasticity of a real human scalp and skull. It is used for cutting, suturing, punching, etc. The surface of the model should have real tactile feedback so that learners can feel the resistance and elasticity similar to that of a real human body.
[0114] Removable skull piece: The skull inside the model is usually designed to be removable or openable to facilitate the display of internal structures and allow learners to simulate craniotomy. According to teaching needs, the thickness of the skull can be adjusted to simulate anatomical differences under different ages, genders and pathological conditions.
[0115] Internal multi-layer structure: The simulation head model contains multiple anatomical layers inside, simulating different parts of the brain, including meninges, brain parenchyma, ventricular system, vascular network, etc. These layers should be able to truly reproduce human anatomy and facilitate learners to conduct in-depth anatomical and pathological learning.
[0116] Simulated brain tissue material: The internal brain tissue is made of highly simulated elastic material to simulate the real brain texture and reaction, especially to show the changes in tissue and pressure during brain abscess.
[0117] Preferably, the simulation head model in this embodiment has the following advantages:
[0118] Modular design: In order to adapt to different teaching needs, the internal structure of the simulation head model can be modular, allowing different components to be replaced to simulate different pathological conditions. For example, different types of brain tissue modules can be replaced to simulate traumatic brain edema, infected brain abscess, or brain abscess caused by stroke.
[0119] Replacement of consumable parts: Due to the need for repeated operations, some parts in the model (such as brain tissue and blood vessels) can be designed to be replaceable to ensure that the effect of each operation is similar to the actual clinical operation.
[0120] The brain abscess simulation module is arranged in the simulated head model, and a cavity is arranged inside the brain abscess simulation module, and brain abscess simulation is realized by injecting gas or liquid into the cavity, including the increase of volume, deformation of shape and physiological changes caused to brain tissue by brain abscess. When simulating brain abscess, learners can observe the effects of different degrees of brain abscess by adjusting system parameters, including displacement and compression of brain tissue and changes in intracranial pressure.
[0121] Wherein, the brain abscess control module is used to control the data of injected gas or liquid according to the abscess data to simulate different degrees of abscess effects;
[0122] Wherein, the intracranial pressure monitoring module is arranged in the simulation head model, and is used to monitor the intracranial pressure changes in real time. In this embodiment, the intracranial pressure monitoring module is a sensor built into the simulation head model. Furthermore, the intracranial pressure monitoring module is also used to:
[0123] The acquired real-time monitoring data is sent to a display or a VR system to help learners understand the physiological consequences of brain abscess; the real-time monitoring data includes changes in intracranial pressure during brain abscess.
[0124] A surgical simulation module, used for simulating a surgical operation process using the simulated head model, comprises:
[0125] Decompressive craniectomy. The model allows learners to simulate a decompressive craniectomy, where the skull of the simulated head can be cut and removed to expose the internal brain tissue for decompressive surgery.
[0126] Ventricular Drainage: Through the internal fluid simulation system, learners can perform ventricular drainage and observe the effect of fluid removal during the drainage process and the relief of brain abscesses.
[0127] In summary, the working principle and functions of the highly simulated brain abscess teaching simulator provided by the embodiment of the present invention can be summarized as follows:
[0128] (1) The simulator will build a 3D high-fidelity model of a virtual patient's brain based on the real human anatomical structure. The model can dynamically simulate the formation, expansion and compression of brain abscesses on surrounding brain tissues. Then, through precise mathematical models and simulation algorithms, the pathological process of brain abscesses is simulated, including the growth of abscesses, the inflammatory response of surrounding brain tissues, changes in intracranial pressure, etc. Finally, the patient's clinical symptoms such as headache, nausea, impaired consciousness, neurological deficits, etc. are simulated, which change with the progression of the abscess.
[0129] (2) Learners can observe these symptoms and evaluate them using a post-computer simulation of the impact diagnostic tool, allowing learners to see the size and location of the abscess and its impact on surrounding structures. The simulator can provide virtual surgical training for brain abscesses, such as abscess drainage and craniotomy. Through a realistic simulated surgical environment, learners can experience the surgical process and improve their skills through repeated operations. Simulated drugs can provide simulation of treatment effects, and learners can try different antibiotic treatment options and observe their effects on virtual patients.
[0130] (3) The simulator can monitor learners’ operations in real time and provide immediate feedback. For example, when learners are performing a surgical operation, the system will analyze the accuracy of the operation. After completing the simulation, the system will generate a detailed evaluation report, including analysis of diagnostic accuracy, treatment effect, and operational standardization, to help learners understand their learning progress and areas for improvement.
[0131] From the above description, it can be seen that the highly simulated brain abscess teaching simulator provided by the embodiment of the present invention has the following advantages:
[0132] (1) The existing brain abscess simulator will open up a new path for clinical medicine teaching, and through the simulator, many clinical teaching methods that cannot be realized can be brought closer to clinical practice for medical students.
[0133] (2) Brain abscess simulators are widely used and can solve the clinical diagnosis and treatment teaching of most critical intracranial infections.
[0134] (3) The development of brain abscess simulators can help shorten the training period of neurosurgeons.
[0135] Furthermore, an embodiment of the present invention provides a simulation method of a highly simulated brain abscess simulator, comprising:
[0136] Prepare the hardware equipment required for simulation, including a highly simulated brain abscess teaching simulator, display or VR system;
[0137] Inject gas or liquid into the cavity of the simulated head model to simulate the dynamic process of brain edema. During this simulation, learners can observe the effects of brain abscesses of different levels by adjusting system parameters, including displacement and compression of brain tissue and changes in intracranial pressure.
[0138] A sensor is built into the highly simulated brain abscess teaching simulator to monitor and display the changes in intracranial pressure in real time. The data obtained by the sensor is transmitted to a display or VR system to help learners understand the physiological consequences of brain abscess.
[0139] Simulate the operation of decompressive craniectomy based on a highly realistic brain abscess teaching simulator;
[0140] Ventricular drainage is performed through the liquid simulation system inside the highly simulated brain abscess teaching simulator, and with the help of a display or VR system, learners can observe the effect of fluid removal during the drainage process and the relief of brain abscess.
