Description

Technical Field

[0001] This invention relates to the field of surgical aids technology, and in particular to an aid method and system for spinal surgery. Background Technology

[0002] Surgical auxiliary equipment refers to a collective term for various professional instruments, devices, and systems used throughout the entire surgical procedure to assist in surgical operations, ensure surgical safety, improve surgical efficiency and accuracy, and assist in completing surgical-related tests and nursing care. It is an important component of operating room medical equipment, covering multiple stages such as preoperative preparation, intraoperative operation, and immediate postoperative care, and is adapted to the specific needs of different surgical fields such as general surgery, orthopedics, neurosurgery, and spinal surgery.

[0003] In spinal surgery, modular surgical beds are commonly used. These beds are equipped with hydraulic or electric lifting, tilting, and flexion / extension adjustment mechanisms, allowing for basic adjustments to the bed's height and angle to accommodate different surgical positions, such as prone and supine. The beds feature guardrails and support panels on both sides to prevent patients from falling. Additionally, shelves and instrument racks are provided around the bed for storing surgical instruments and supplies, facilitating the surgeon's operation.

[0004] Because spinal surgery demands extremely high precision and flexibility in the operating space, doctors need to perform multi-directional and multi-angle operations around the treatment bed. Furthermore, surgical instruments need to be frequently retrieved and changed during the procedure. Fixed-angle guardrails can create fixed spatial obstructions, which can easily lead to the guardrails encroaching on the operating space, limiting the doctor's range of motion and flexibility, and even causing the doctor to bump into the guardrails during the operation. This not only reduces the convenience and efficiency of the surgical procedure but may also increase the risk of surgical errors due to the limited operating space. Summary of the Invention

[0005] To improve the convenience and efficiency of spinal surgery, this invention provides an auxiliary method and system for spinal surgery.

[0006] In a first aspect, the present invention provides an auxiliary method for spinal surgery, employing the following technical solution: An adjunct method based on spinal surgery includes: Collect information on the patient's physical characteristics while on the treatment bed, the real-time status of the protective devices pre-installed on the treatment bed, and the doctor's monitoring information; Retrieve real-time angle values ​​and real-time position points based on real-time status; Determine the baseline angle value for protection by combining real-time location points with body characteristics; Calculate the difference between the protection reference angle value and the real-time angle value and use it as the initial angle deviation value; The doctor's identity information and individual actions are determined based on the doctor's test results. The operation is estimated based on the doctor's individual movements, and the required angle value of the movement is determined by combining the doctor's identity information and real-time location. The angle adjustment value is determined by combining the initial angle deviation value and the angle value required for the action, and the angle adjustment value is output to the protective device preset on the treatment bed to adjust the angle.

[0007] By adopting the above technical solution, the system collects information on the patient's physical characteristics, real-time status, and doctor's detection, retrieves the real-time angle value and location of the protective device, determines the protective reference angle value, calculates the initial angle deviation value, and combines the doctor's detection information with the doctor's identity information and individual actions to determine the required angle value for the action. Finally, the system combines and outputs the determined angle adjustment value to the protective device preset on the treatment bed to adjust the angle. This allows the angle adjustment of the protective device to be both reasonable for patient protection and doctor operation. Furthermore, by quantifying the angle deviation and action requirements, the angle adjustment value can adapt to the doctor's operation, reducing the probability of the protective device encroaching on the surgical operation space, thereby improving the convenience and efficiency of the surgical operation during spinal surgery.

[0008] Optionally, methods for determining the protection reference angle value include: Based on the body's characteristics, retrieve the body's baseline parameters, scoliosis parameters, and body orientation; Determine the actual width of the body by combining body baseline parameters and body orientation; The body spacing value is calculated by combining the actual body width value with the preset bed reference width value; The influence value of scoliosis is determined by combining spinal scoliosis parameters, real-time location points, and body orientation. Calculate the product between the body spacing value and the lateral bending effect value, and use it as the spacing adjustment value; The required angle value for protection is determined based on the spacing adjustment value, and this required angle value is used as the reference angle value for protection.

[0009] By adopting the above technical solution, the body's baseline parameters, scoliosis parameters, and body orientation are retrieved based on the patient's physical characteristics. Through multi-step quantitative calculations, the body spacing value and scoliosis influence value are obtained. The spacing adjustment value is then obtained by multiplying the two values, and the protection baseline angle value is determined. This achieves a precise match between the protection baseline angle value and the patient's individual physical condition. At the same time, by quantifying the difference between the body width and the bed spacing, as well as the impact of scoliosis on protection, a precise baseline that fits the patient's actual protection needs is provided for subsequent angle adjustments.

[0010] Optional methods for determining the actual body width include: Height and width parameters are retrieved based on body baseline parameters; Determine the reference value for body width by combining height and body width parameters; Determine the influence value of orientation based on the body's orientation; Calculate the product between the orientation influence value and the body width reference value and use it as the actual body width value.

[0011] By adopting the above technical solution, the body width reference value is determined by retrieving the height and width parameters from the body baseline parameters. Then, the actual body width value is calculated by combining the influence value of the body's orientation. This takes into account the correlation between the patient's height and body width, and also incorporates the influence of the body's orientation, so that the body width reference value is more in line with the patient's body proportion characteristics and accurately reflects the actual body width state of the patient lying on the treatment bed. This provides more realistic basic data for the subsequent calculation of body distance values.

[0012] Optional methods for determining body width reference values ​​include: Retrieve the body width location point and its corresponding body width value based on the body width parameter; Calculate the distance between adjacent body width locations and use it as the adjacent body width distance value; Determine the relative adjustment value for body width by combining adjacent body width distance values ​​and height values; Determine the baseline value of body width based on the body width value; Calculate the sum between the relative adjustment value of body width and the baseline value of body width, and use it as the reference value for body width.

[0013] By adopting the above technical solution, the body width location point and corresponding body width value are retrieved through the body width parameter, the distance value between adjacent body widths is calculated, and the relative adjustment value of body width is determined by combining the height value. Then, the body width reference value is obtained by combining the body width benchmark value. The body width reference value can accurately reflect the body width difference of different parts of the patient's body and the body width ratio corresponding to the height, providing a more accurate reference for calculating the actual body width value.

[0014] Optional methods for determining the lateral bending influence value include: The location and degree of scoliosis are retrieved based on scoliosis parameters. Calculate the distance between the real-time location point and the lateral bending location point and use it as the lateral bending distance value; Determine the reference direction of the lateral bend based on the lateral bend location point; Analyze the reference direction of lateral bending and the orientation of the body to determine the lateral bending deviation angle; The lateral bending adjustment value is determined by combining the lateral bending deviation angle value and the lateral bending distance value. Calculate the product between the lateral bending degree value and the lateral bending adjustment value, and use it as the lateral bending influence value.

[0015] By adopting the above technical solution, the location and degree of scoliosis are retrieved through scoliosis parameters. The scoliosis distance value is calculated and the scoliosis deviation angle value is analyzed. The scoliosis adjustment value is gradually obtained and combined with the scoliosis degree value to determine the scoliosis impact value. This allows the scoliosis impact value to accurately reflect the actual impact of scoliosis on the patient's protection needs. This makes the calculation of subsequent distance adjustment values ​​more in line with the special protection needs of scoliosis patients and improves the adaptability of the protection benchmark angle value to patients with spinal diseases.

[0016] Optionally, methods for determining the predicted actions include: Determine patient identification information based on physical characteristics; Retrieve surgery type based on patient identity information; Determine the baseline surgical procedures based on the type of surgery; Determine the degree of motion matching by combining individual doctor movements with surgical baseline movements; Selecting actions for surgery based on action matching degree; Based on the selected surgical actions, the predicted surgical actions are determined and used as the predicted operational actions.

[0017] By adopting the above technical solution, the patient's identity information is determined by the patient's physical characteristics and the type of surgery is retrieved. The baseline surgical action is determined by combining the surgical type. Then, the selected surgical action is selected by the matching degree between the doctor's individual action and the baseline surgical action, and the predicted operation action is determined. This achieves accurate judgment of the doctor's subsequent operation prediction action, making the operation prediction action more in line with the actual operation scenario, and providing an accurate basis for determining the angle value of subsequent action requirements that fits the doctor's operation.

[0018] Optional methods for selecting surgical actions include: The corresponding surgical baseline action is retrieved based on the action matching degree and used as the current matching action; Determine the current baseline matching degree based on the current matching action; Calculate the difference between the action matching degree and the current baseline matching degree and use it as the matching deviation value; Determine the deviation reference value based on the matching deviation value; The deviation reference values ​​are sorted from smallest to largest, and the current matching action corresponding to the first-ranked deviation reference value is selected as the surgical action.

[0019] By adopting the above technical solution, the current matched action is retrieved through the action matching degree and the matching deviation value is calculated. Then, the deviation reference value is determined based on the matching deviation value. The current matched action with the smallest deviation reference value is selected as the surgical action. This ensures the highest degree of fit between the surgical action and the doctor's individual action and the surgical baseline action, providing a more accurate action basis for determining the operation prediction action.

[0020] Optional methods for determining the deviation reference value include: Curve analysis is performed based on the matching deviation value to obtain the matching deviation curve; Determine the curve curvature value and overall length value based on the matching deviation curve; Retrieve curvature coverage based on curve curvature value; Determine the curvature length value based on the curvature coverage range; Calculate the ratio between the curvature length value and the overall length value and use it as the length ratio value; A comprehensive reference value is determined by combining the curve curvature value, length ratio value, and matching deviation value, and this comprehensive reference value is used as the deviation reference value.

[0021] By adopting the above technical solution, a matching deviation curve is obtained by performing curve analysis on the matching deviation value. Then, parameters such as curve curvature value and overall length value are extracted to calculate the length ratio value. Finally, the deviation reference value is determined by combining multiple parameters, so that the deviation reference value can more comprehensively and accurately reflect the degree of matching deviation between the doctor's single action and the surgical baseline action.

[0022] Optional methods for determining the motion requirement angle value include: Determine the range of action requirements based on the estimated actions; Determine the impact value of the doctor's operation based on the doctor's identity information; Types of tools used for collecting protective equipment; Determine the tool's impact value based on the type of tool; The sum of the influence values ​​of the calculation tools and the influence values ​​of the doctor's actions is used as the action influence value; Determine the actual impact range by combining the action's impact value with the required range of the action; The position adjustment angle value is determined based on the actual impact range and real-time location, and the position adjustment angle value is used as the motion requirement angle value.

[0023] By adopting the above technical solution, the range of action requirements is determined by predicting the operation, the impact value of the doctor's operation is determined by combining the doctor's identity information, and the impact value of the tool type of the protective device is determined by incorporating the tool type. After multiple calculations, the actual impact range is obtained, and the action requirement angle value is determined by combining the real-time position point. This ensures that the action requirement angle value not only conforms to the doctor's operating habits and surgical action requirements, but also adapts to the tool placement and usage requirements of the protective device. At the same time, adjustments are made in conjunction with the real-time position point of the protective device to match the action requirement angle value with the actual position of the protective device, thereby improving the adaptability and practicality of angle adjustment for the doctor's surgical operation.

[0024] Secondly, the present invention provides an auxiliary system for spinal surgery, which adopts the following technical solution: An assistive system for spinal surgery, comprising: The data acquisition module is used to collect information on physical characteristics, real-time status, doctor's examination information, and the types of tools used. A memory storing a program for implementing an auxiliary method for spinal surgery as described in any of the first aspects; The processor loads and executes programs stored in memory.

[0025] In summary, the present invention has at least one of the following beneficial technical effects: 1. By collecting information on body characteristics, real-time status, and doctor's detection, and retrieving the real-time angle value and real-time position of the protective device to determine the protective reference angle value, the initial angle deviation value is calculated. At the same time, the doctor's identity information and individual actions are retrieved in combination with the doctor's detection information to determine the angle value required for the action. Finally, the determined angle adjustment value is output to the protective device preset on the treatment bed to adjust the angle. This allows the angle adjustment of the protective device to be both reasonable for patient protection and doctor operation. Furthermore, by quantifying the angle deviation and action requirements, the angle adjustment value can adapt to the doctor's operation, reducing the probability of the protective device encroaching on the surgical operation space, thereby improving the convenience and efficiency of the surgical operation during spinal surgery. 2. By retrieving body baseline parameters, scoliosis parameters, and body orientation based on physical characteristics, and through multi-step quantitative calculations, the body spacing value and scoliosis impact value are obtained. Then, the spacing adjustment value is obtained by multiplying the two and determining the protection baseline angle value. This achieves a precise match between the protection baseline angle value and the individual patient's physical condition. At the same time, by quantifying the difference between the body width and the bed spacing and the impact of scoliosis on protection, a precise baseline that fits the actual protection needs of the patient is provided for subsequent angle adjustments. 3. By estimating the required movement, the range of movement needs is determined. Combined with the doctor's identity information, the impact value of the doctor's operation is determined. At the same time, the impact value of the tool type of the protective device is determined. Through multiple calculations, the actual impact range is obtained, and the required angle value of the movement is determined by combining it with the real-time position point. This ensures that the required angle value of the movement not only conforms to the doctor's operating habits and surgical movement needs, but also adapts to the tool placement and usage needs of the protective device. In addition, adjustments are made based on the real-time position point of the protective device to match the required angle value of the movement with the actual position of the protective device, thereby improving the adaptability and practicality of the angle adjustment for the doctor's surgical operation.

Next, based on the doctor's monitoring information, the method retrieves the doctor's identity and individual movements. Combined with the surgical type, it determines the predicted operational movements through movement matching. Integrating factors such as the doctor's operation and tool types, it determines the required angle value for the movement. Finally, it calculates and outputs the angle adjustment value of the protective device, which is then preset on the treatment bed to adjust the angle, allowing the protective device to adapt to the doctor's operation. This reduces the probability of the protective device obstructing the surgical operation space, thereby improving the convenience and efficiency of spinal surgery.
