[0032] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] Embodiment 1: As shown in the attached Figure 1 , Attachment Figure 2 As shown: The present invention provides a trigeminal nerve surgery posture trainer, comprising a wedge-shaped pad 1 and a training component. The wedge-shaped pad 1 can fit the curve of the human head and body well, and the human shoulder is located on the top of the wedge-shaped pad 1, which effectively disperses the pressure and reduces the risk of pressure sores at the contact part between the patient's body and the trainer during long-term training, thereby greatly improving the comfort of the patient during training;

[0034] As attached Figure 3 As shown: a control slot 6 is provided in the wedge-shaped pad 1, a rotation slot 8 is provided on the inner wall of the control slot 6, a positioning frame 9 is fixedly connected to the inner wall of the rotation slot 8, and the tray 2 is controlled to swing through the rotation slot 8 by arranging electrical components in the control slot 6, and keeps hovering after swinging to a set angle, so as to be used for body position training;

[0035] The training assembly includes a tray 2, a support rod 12, a swing rod 13 and a driving assembly; the driving assembly is installed in the control slot 6, the support rod 12 is fixed to the side wall of the tray 2, the support rod 12 is rotatably installed at the positioning frame 9, and one end of the swing rod 13 is fixed to the side of the support rod 12;

[0036] As attached Figure 4 As shown: the driving assembly includes a power supply assembly 7, a servo motor 11, a cam 17 and a swing wheel 15. The power supply assembly 7 and the servo motor 11 are both installed in the control slot 6. The output end of the servo motor 11 is connected to a driving shaft 16. The cam 17 is installed around the driving shaft 16. A connecting slot 14 is opened at one end of the swing rod 13. The swing wheel 15 is rotatably installed in the connecting slot 14. The positions of the swing wheel 15 and the cam 17 correspond. The swing wheel 15 has a large deadweight. Under the influence of the deadweight of the swing wheel 15, the swing wheel 15 can drive one end of the swing rod 13 to move downward, thereby tilting the tray 2 through the support rod 12, and supporting the head through the tray 2, so that the head can be placed at a corresponding angle.

[0037] The servo motor 11 controls the driving shaft 16 to rotate, and the driving shaft 16 drives the cam 17 to rotate. When the raised portion of the cam 17 reaches the swing wheel 15, the swing wheel 15 is lifted, so that the position of the tray 2 is lowered, and the angle of the tray 2 is adjusted. By adjusting the angle of the tray 2, body posture training at different angles can be performed; by keeping the position of the cam 17 stable, the position of the tray 2 can be kept stable.

[0038] A limit assembly is installed between the swing wheel 15 and the cam 17, and the limit assembly includes a limit rod 19 and a limit wheel 20. Guide rails 18 are provided around the swing wheel 15 and the cam 17. Limit wheels 20 are installed at both ends of the limit rod 19, and the limit wheels 20 are rollingly installed in the guide rails 18. By setting the limit rod 19 and the limit wheel 20, when the cam 17 rotates, the swing wheel 15 always keeps in contact with the outer wall of the cam 17 through the action of the limit rod 19; the two sets of limit wheels 20 always remain in the guide rails 18, thereby ensuring that the swing wheel The position stability of 15 can avoid the situation that the swing wheel 15 is tilted due to the overweight of the tray 2; the limiting wheel 20 rolls in the guide rail 18, which effectively reduces wear and tear and ensures the stability of the use of the limiting component; the limiting rod 19 and the limiting wheel 20 ensure the close contact and stable transmission between the swing wheel 15 and the cam 17, avoiding the structural instability caused by the overweight of the tray 2 or external interference, and effectively reducing the wear of the components, extending the service life of the equipment, and ensuring the reliability of the trainer under long-term and high-intensity use.

[0039] A control panel 4 and a wiring port 5 are installed on the outer wall of the wedge-shaped pad 1, and a pressure sensor is installed on the surface of the tray 2. The pressure sensor and the drive component are electrically connected to the control panel 4. The control panel 4 has a built-in microcontroller, a power control circuit, a speaker and a timing module, and the wiring port 5 is electrically connected to the power component 7; a support seat 10 is installed on the inner surface of the control slot 6, and a servo motor 11 is installed at the support seat 10; the deflection angle of the tray 2 can be set through the control panel 4, and the pressure sensor is used to sense the pressure of the human head. When the sensor senses the pressure, the timing module is triggered. After the patient lies on it, the timing is automatically started. The interval time is set through the timing module. When the set time is reached, the speaker makes a sound and prompts the training time. For example, the speaker makes a sound every half an hour.

[0040] The timing module and speaker integrated in the control panel 4 realize the automatic management and timing reminder function of the training time; the patient does not need to time it by himself, the trainer will automatically remind according to the set time interval, which is convenient for the patient to arrange the training rhythm reasonably and avoid affecting the training effect due to too long or too short training time. Medical staff can also evaluate and adjust the patient's training situation in time according to the prompts, which improves the scientificity and standardization of the training process, and also improves the overall training management efficiency.

[0041] A flexible cushion layer 26 is provided on the surface of the wedge-shaped pad 1. The flexible cushion layer 26 is made of medical sponge material. The flexible cushion layer 26 ensures the comfort of the wedge-shaped pad 1 during body position training.

[0042] As can be seen from the above, after the device is powered on, in the initial state, since the swing wheel 15 is heavy, it will drive one end of the swing rod 13 connected thereto to move downward. The other end of the swing rod 13 is connected to the support rod 12 fixed to the side wall of the tray 2, and the support rod 12 can rotate on the positioning frame 9, so that the tray 2 is tilted upward at a certain angle.

[0043] When the angle of the tray 2 needs to be changed, a command is sent to the servo motor 11 in the control slot 6 through the control panel 4, and the servo motor 11 drives the drive shaft 16 to rotate, and the cam 17 on the drive shaft 16 also rotates accordingly; when the raised part of the cam 17 rotates to contact the swing wheel 15, the swing wheel 15 is lifted upward;

[0044] Since the swing wheel 15 is installed in the connecting groove 14 of the swing rod 13 and can rotate, when the swing wheel 15 is lifted, the swing rod 13 will rotate around the connection point with the support rod 12, thereby lowering the angle of the tray 2; by controlling the rotation angle and direction of the servo motor 11, the tray 2 can be accurately adjusted to different angles to meet various body posture training requirements.

[0045] During the whole process, the limiting assembly plays a key role. The limiting wheels 20 at both ends of the limiting rod 19 roll in the guide rails 18 of the cam 17 and the swing wheel 15 respectively, ensuring that the swing wheel 15 is always in close contact with the cam 17, avoiding the swing wheel 15 from being separated from the cam 17 due to factors such as the weight of the tray 2, thereby ensuring the accuracy and stability of the angle adjustment and reducing the friction loss between the components.

[0046] When the patient places his head on the tray 2, the pressure sensor on the surface of the tray 2 detects the pressure change and transmits the signal to the microcontroller in the control panel 4. After receiving the signal, the microcontroller immediately starts the timing module to start timing; the user can set the reminder time interval in advance through the control panel 4, such as half an hour; when the timing reaches the set time interval, the control panel 4 will control the speaker to make a sound to remind the patient and medical staff that the training time is up so that they can proceed to the next training session or rest and adjust.

[0047] Embodiment 2, as attached Figure 5 As shown: a lifting groove 101 is opened on the surface of the wedge-shaped pad 1, and an angle monitoring component is installed at the lifting groove 101, which includes a lifting component, a camera 23 and a control board 25. The camera 23 is installed at the telescopic end of the lifting component, and the camera 23 faces the position of the tray 23. The control panel 4, the power supply component 7, the camera 23 and the servo motor 11 are all electrically connected to the control board 25.

[0048] The lifting assembly includes an electric push rod 21 and a support rod 22 . The electric push rod 21 is installed in the control slot 6 . The telescopic end of the electric push rod 21 is connected to the support rod 22 . The camera 23 is installed at one end of the support rod 22 .

[0049] A sealing plate 24 is disposed on the upper surface of the camera 23 , and the size of the sealing plate 24 is adapted to the lifting slot 101 .

[0050] The control panel 4 integrates an image acquisition module, an image preprocessing unit, an edge detection and feature extraction unit, an angle calculation unit and a control unit;

[0051] The image acquisition module receives image data acquired by the camera 23;

[0052] The image preprocessing unit preprocesses the collected color image, and the preprocessing includes grayscale conversion and filtering and denoising processing;

[0053] The edge detection and feature extraction unit calculates the components of the image gradient in the x and y directions respectively through the Sobel operator to obtain the gradient amplitude and direction; then extracts the edge contours of the human jaw and the tray plane through non-maximum suppression and double threshold detection; and fits the straight lines of the jaw and tray plane from the edge pixels in combination with the Hough transform;

[0054] The angle calculation unit calculates the slope of the straight line between the mandible and the plane of the tray 2, and then calculates the angle between the mandible of the human body and the plane of the tray 2;

[0055] The control unit compares the angle information with the target angle, and controls and adjusts the angle of the adjustment tray 2 so that the angle of the human jaw reaches the expected value.

[0056] As can be seen from the above, the power supply assembly 7 provides power support for the entire system, the camera 23 performs image acquisition under the control of the control board 25, the control panel 4 is used for system parameter setting and information display and other functions, and the servo motor 11 adjusts the angle of the tray 2 according to the instructions of the control board 25.

[0057] The electric push rod 21 is installed in the control slot 6, and drives the support rod 22 to move through its telescopic function, and the camera 23 is installed at one end of the support rod 22, so that the camera 23 can realize the lifting and lowering adjustment of the position under the drive of the electric push rod 21, ensuring that the image can be accurately collected toward the position of the tray 2. In addition, the sealing plate 24 on the upper surface of the camera 23 is adapted to the lifting slot 101 in size. When the camera 23 is not working, the sealing plate 24 can close the lifting slot 101, thereby protecting the camera 23 and preventing dust and other impurities from entering and affecting its performance.

[0058] The image acquisition module receives the image data collected by the camera 23. The camera 23 collects images including the human jaw and the plane where the tray 2 is located. The frame rate of the acquisition is adjustable, ranging from 15 to 60 frames per second, and the image resolution is not less than 640×480 pixels to meet the requirements of accurate acquisition. The collected image data is the basis for subsequent processing, and the image acquisition module will transmit these data to the image preprocessing unit in real time.

[0059] The image preprocessing unit preprocesses the collected color image. The first is grayscale conversion. The weighted average method is used to convert the RGB value of each pixel of the color image into a grayscale value. The conversion formula is grayscale value = 0.299×R+0.587×G+0.114×B. This is done to reduce the amount of data processing, because the grayscale image only contains brightness information, which is easier to process than the color image data, and it can also retain the main image information. Then filtering and denoising are performed. Based on the two-dimensional Gaussian function, a discrete Gaussian kernel size of 3×3-7×7 is generated, and the image is convolved to remove noise. During the image acquisition process, noise may be generated due to various interferences. Filtering and denoising can effectively improve the image quality and provide a clearer image for subsequent edge detection.

[0060] The edge detection and feature extraction unit operates on the preprocessed image.

[0061] The Sobel operator is used to calculate the components of the image gradient in the x and y directions respectively, and then the gradient amplitude and direction are obtained.

[0062] Sobel operator in the x direction and the Sobel operator in the y direction Convolution with the image is used to detect the brightness changes of the image in the horizontal and vertical directions, so as to find the edge position. Then the gradient amplitude is subjected to non-maximum suppression and double threshold detection (the high threshold T in the double threshold detection is h The value range is 50-150, the low threshold T l The value range is 20-50), and the edge contours of the human jaw and tray planes are accurately extracted; non-maximum suppression is to refine the edge, and only the pixels with the largest amplitude in the gradient direction are retained as edge candidates; dual threshold detection further determines the true edge pixels according to the set threshold range, and excludes some weaker edge responses. Finally, the straight line representing the jaw and tray plane is fitted from the edge pixels in combination with the Hough transform. The parameter spatial resolution of the Hough transform is not less than 0.1 radians and 0.1 pixels. In this way, the straight line that can represent the jaw and tray plane can be effectively found from the complex edge pixels, providing key geometric information for angle calculation.

[0063] The angle calculation unit calculates the slopes of the straight lines between the human jaw and the plane of the tray 2 according to the straight lines fitted by the edge detection and feature extraction unit.

[0064] Then use The angle α (radian) between the two straight lines is calculated and then converted into an angle system with a calculation accuracy of 0.1 degree. This angle value accurately reflects the angle between the human jaw and the plane of the tray 2.

[0065] The control unit receives the angle information from the angle calculation unit and compares it with the target angle. If there is a difference between the current angle and the target angle, a control algorithm (such as PID control) is used to determine the control signal for adjusting the angle of tray 2. Taking PID control as an example, it comprehensively considers the size of the angle difference (proportional term), the accumulation of the angle difference (integral term) and the rate of change of the angle difference (differential term), and uses a specific formula Calculate the control quantity u(t), where K p ,K i ,K d are the proportional, integral and differential coefficients respectively, and Δθ is the angle difference.

[0066] The control quantity will be converted into a motor drive signal and sent to the servo motor 11; the servo motor 11 operates according to the received signal, the drive shaft 16 drives the cam 17, the cam 17 pushes the swing wheel 15 and the swing rod 13, and the swing rod 13 drives the tray 2 to rotate around the fulcrum via the support rod, thereby accurately changing the angle of the tray 2; during the angle adjustment process of the tray 2, the control unit continuously receives data from the angle calculation unit and dynamically adjusts the control signal until the angle between the human body's lower jaw and the plane of the tray 2 is stabilized near the target angle within a certain error range, such as the error threshold is set to 1 degree, to achieve precise control of the angle.

[0067] During the training process, there is no need for frequent manual measurement and adjustment. The camera collects images, and after coordinated processing by various units, the accurate monitoring of the human jaw angle is automatically completed. The angle calculation unit has an accuracy of up to 0.1 degrees, ensuring that the actual angle data can be obtained in a timely and accurate manner. Based on this data, the control unit combines advanced PID and other algorithms to respond quickly and automatically adjust the tray angle, so that the human jaw angle quickly and stably reaches the expected value, greatly improving the efficiency and accuracy of angle adjustment and reducing human errors.

[0068] During the training process, the human jaw angle may change due to various factors; the device can monitor these changes in real time, and the control unit continuously receives data from the angle calculation unit. Once it detects that the angle deviates from the target value, it will automatically adjust it immediately to ensure that the human jaw is always at an angle that meets the requirements of surgical position training, providing stable and accurate angle support for training.
