[0002] Electrostatic discharge (ESD), or transient surge, refers to the physical phenomenon of electrostatic charge transfer or rapid potential drop between objects at different potentials. It can easily cause malfunctions in integrated circuits (ICs) or circuit systems, or electronic products. To reduce losses caused by ESD and transient surge events across various industries, major companies and universities have established their own ESD laboratories and research teams, dedicated to mitigating the losses caused by ESD and transient surge events.
[0003] In endoscopic surgery, medical endoscopes are often used in conjunction with high-frequency electrosurgical units. These units typically operate at voltages exceeding AC 6000V, a high voltage that can easily damage the electronic components within the endoscope. Common ESD protection solutions for medical endoscopes involve encasing the endoscope in insulating material and a metal sheath, which is costly, complex, and often only achieves ESD protection at the edge of AC 6000V, with some products failing the ESD test conducted by the high-frequency electrosurgical unit. Therefore, improving the ESD protection performance of medical endoscopes without changing the module size is a key issue that needs to be addressed.

[0044] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.
[0045] Please refer to Figures 1-5 This invention proposes an ESD release method for a medical endoscope module.
[0046] This embodiment provides an ESD release method for a medical endoscope module, comprising:
[0047] S1: Obtain the first parameter information input by the sensing unit, the first parameter information including: the positional relationship between the ESD generating end and the ESD influencing end;
[0048] S2: Establish an electrostatic field simulation model based on the electrostatic field generated at the ESD generation end, and use the finite element method to calculate the electric field intensity and potential distribution at the ESD generation end in space.
[0049] S3: Construct the spatial coordinate system xyz at the ESD generation end and evenly divide it into grid points;
[0050] S4: Calculate the electric field intensity and potential distribution of each grid point according to the position of the spatial coordinate system, and generate grid point data according to the electric field intensity and potential distribution of the grid points;
[0051] S5: Substitute the first parameter information into the grid point to obtain the grid point data. Compare the grid point data with the safety threshold of the ESD-affected end. If the grid point data is greater than the safety threshold, execute the ESD release instruction according to the difference.
[0052] In this embodiment, the ESD generating end is a medical high-frequency electrosurgical unit, and the ESD influencing end is a medical endoscope module. The system acquires first parameter information input from the sensing unit. This information includes the positional relationships between electronic components within the high-frequency electrosurgical unit and the medical endoscope. This step helps the system understand where electrostatic discharge might occur and which parts it might affect. Based on the electrostatic field generated at the ESD generating end, an electrostatic field simulation model is established. The finite element method is used to calculate the space at the ESD generating end to obtain the electric field strength and potential distribution. This step provides information on the electric field distribution under a specific voltage, facilitating prediction of potential ESD events. In cases of potential ESD events, such as ESD released by a high-frequency electrosurgical unit, which can burn out the electronic components of a medical endoscope module, the following steps can be taken: First, an xyz coordinate system is constructed in the space where the ESD is generated, and grid points are evenly divided. This step provides the basis for subsequent calculations of electric field strength and potential distribution. The electric field strength and potential distribution of each grid point are calculated based on the position of the spatial coordinate system, and then corresponding data is generated according to the grid points. This allows for obtaining electric field information at any given spatial location. The first parameter information is substituted into the grid points to obtain grid point data, which is then compared with the safety threshold of the endoscope's electronic components. If the calculated grid point data is greater than the safety threshold, an ESD release command is executed. This step ensures that when the electric field strength exceeds the safety threshold, the system can take timely action to avoid potential damage. In summary, by accurately predicting and controlling ESD using the above method, the safety of medical endoscope modules when using high-frequency electrosurgical units can be effectively improved, while also reducing the cost and complexity of additional physical protection measures.
[0053] In one embodiment, the method for establishing an electrostatic field simulation model includes:
[0054] Different voltages are applied to the ESD generation terminal to obtain electrostatic field distribution characteristics and extract feature quantities;
[0055] The electrostatic field of the Bureau of Information was calculated using the finite element method. Based on the calculation results, the electric field feature sets at different locations were extracted, and each electric field feature quantity was normalized.
[0056] A prediction model is established using a support vector regression machine, and the electric field features are trained using electric field features of different characteristics as training samples.
[0057] By inputting the electric field characteristics at the same location under different voltages into the prediction model, the influence curves of voltage and distance are obtained;
[0058] By inputting the electric field characteristics at the same voltage at different locations into the prediction model, the influence curves of distance and voltage are obtained.
[0059] This embodiment explains how to predict the effects of electrostatic discharge (ESD) using different voltages, electrostatic field calculations, and machine learning methods. Specific steps include:
[0060] Applying different voltages to the ESD generation terminal, obtaining electrostatic field distribution characteristics and extracting feature quantities: This is to understand how the electrostatic field is distributed at the ESD generation terminal under different voltages, and its main characteristics.
[0061] The finite element method is used to calculate the electrostatic field: based on the calculation results, electric field feature sets are extracted at different locations, and each electric field feature is normalized; this is to eliminate the influence of data scale and make all feature quantities at the same scale level.
[0062] A prediction model is established using support vector regression: the electric field features with different characteristics are used as training samples to train the electric field features; this step uses machine learning methods to establish a model that can predict the electric field strength and potential distribution.
[0063] By inputting the electric field characteristics at the same location under different voltages into the prediction model, the influence curves of voltage and distance are obtained: this step is to understand how the electric field strength changes when the voltage is different at the same location.
[0064] The electric field characteristics at different locations under the same voltage are input into the prediction model to obtain the influence curves of distance and voltage: this step is to understand how the electric field strength changes when the voltage is the same but the location is different.
[0065] This method allows for a deeper and more precise understanding of the electrostatic field distribution at the ESD generation point, as well as the impact of voltage and position changes. This is of great significance for optimizing ESD protection schemes for medical endoscope modules and improving the safety and stability of the equipment.
[0066] In another embodiment, since the distance between the high-frequency electrosurgical unit and the medical endoscope module changes during use, the changes in positional relationship and the changes in the voltage used by the high-frequency electrosurgical unit can be predicted by the voltage-distance influence curve and the distance-voltage influence curve, so that the medical endoscope module can release more static electricity in advance to prevent the internal electronic components from being burned out.
[0067] Furthermore, the accuracy evaluation method for the electrostatic field simulation model includes:
[0068] A partial discharge experimental platform for ESD generation was built to conduct discharge experiments, and the voltage U generated during the experiment was measured. U was applied in the electrostatic simulation model. The electric field intensity at different locations during the experiment was equal to the electric field intensity in the electrostatic simulation model, and the electric field intensity value E at different locations obtained in the electrostatic simulation model satisfied the influence curve of voltage and distance.
[0069] This embodiment describes in detail a method for evaluating and calibrating an electrostatic field simulation model, with the following specific steps:
[0070] To build an ESD generation partial discharge experimental platform for discharge experiments: First, it is necessary to create a real environment to simulate the ESD generation and discharge process, so that data can be collected under real conditions.
[0071] The voltage generated during the experiment is measured as U: In the experiment, the generated voltage value U will be measured and recorded. This is an important parameter for the ESD generation terminal (such as a high-frequency electrosurgical unit).
[0072] Applying U to the electrostatic field simulation model: The voltage value U measured in the experiment is applied to the electrostatic field simulation model so that the model can be simulated under the same voltage conditions.
[0073] The electric field strength at different locations during the experiment is equal to the electric field strength in the electrostatic field simulation model: compare whether the electric field strength at different locations under the same voltage in the experiment and the model is consistent. If the two are consistent or very close, it indicates that the model can accurately simulate the real situation.
[0074] The electric field intensity values E at different locations obtained in the electrostatic field simulation model satisfy the influence curves of voltage and distance: verifying whether the model can accurately reflect the relationship between electric field intensity and voltage and distance. If the expected influence curves are met, it indicates that the model has a good understanding and predictive ability of the dynamic characteristics of ESD.
[0075] Furthermore, the accuracy evaluation method for the electrostatic field simulation model includes:
[0076] A partial discharge experimental platform for ESD generation was built to conduct discharge experiments, and the voltages generated during the experiment were measured as U1 and U2. U1 and U2 were applied in the electrostatic simulation model. During the experiment, the electric field strength at the same location under different voltages was equal to the electric field strength in the electrostatic simulation model. Furthermore, the electric field strength values E1 and E2 at the same location obtained in the electrostatic simulation model satisfied the influence curve of voltage and distance.
[0077] This embodiment describes a method for evaluating and calibrating an electrostatic field simulation model, with the following specific steps:
[0078] To build an ESD generation partial discharge experimental platform for discharge experiments: First, it is necessary to create a real environment to simulate the ESD generation and discharge process, so that data can be collected under real conditions.
[0079] The voltages generated during the experiment are measured as U1 and U2: In the experiment, the voltage values U1 and U2 generated under two different conditions are measured and recorded. These are important parameters for ESD generation terminals (such as high-frequency electrosurgical units).
[0080] Applying U1 and U2 to the electrostatic field simulation model: Applying the voltage values U1 and U2 measured in the experiment to the electrostatic field simulation model, so that the model can perform simulation under the same voltage conditions.
[0081] During the experiment, the electric field strength at the same location under different voltages was equal to the electric field strength in the electrostatic field simulation model. The experiment and the model were compared to determine if the electric field strengths at the same location under different voltages were consistent. If they were consistent or very close, it indicates that the model accurately simulates the real-world situation.
[0082] The electric field strength values E1 and E2 at the same location obtained in the electrostatic field simulation model satisfy the influence curves of voltage and distance: verifying whether the model can accurately reflect the relationship between electric field strength and voltage and distance. If E1 and E2 satisfy the influence curves of U1 and U2 respectively at the same location, it indicates that the model has a good understanding and prediction ability of the dynamic characteristics of ESD.
[0083] In summary, this method can assess the accuracy of electrostatic field simulation models and make corrections or optimizations as needed. In this way, we can more accurately predict and manage ESD issues that medical endoscope modules may encounter when using high-frequency electrosurgical units, thereby improving the safety and stability of the equipment.
[0084] Furthermore, the formulas for the electric field strength and potential distribution include:

[0086]
[0087] In the formula, E is the electric field intensity, L is the distance, and U is the voltage value. It is the Hamiltonian operator, where ε is the dielectric constant. It is electric potential, and ∫ is the Gaussian operator.
[0088] Furthermore, the sensing unit also acquires the voltage at the ESD generation terminal, determines the electric field strength and potential at the ESD generation terminal based on the voltage at the ESD generation terminal, and substitutes the first parameter information into the electrostatic field model to obtain the electric field strength that the ESD-affected terminal will experience.
[0089] Furthermore, the safety threshold is the maximum static charge that the ESD-affected terminal can store. When the value is below the safety threshold, the performance of the ESD-affected terminal is not affected.
[0090] In one embodiment, such as Figure 3 and Figure 4 As shown, the ESD release method of the medical endoscope module is achieved by an electrostatic discharge device executing an electrostatic discharge command.
[0091] The electrostatic discharge device includes: through circuit design, a pin is soldered to the ESD-affected end. When a large amount of charge accumulates on the ESD-affected end, the charge can be guided to the GND_ESD connected to the ESD-affected end through the pin, so as to avoid the charge accumulation ESD damaging the components. In addition, the GND_ESD trace wraps around the module circuit throughout, which can play the role of protecting the module from ESD throughout the process.
