Description

Technical Field

[0001] The present application relates to the technical field of locking distal radius fractures, and more specifically, to an emergency locking device and method for distal radius fractures. Background Art

[0002] Distal radius fracture refers to a fracture of the radius near the wrist. It is a common orthopedic emergency, especially in the elderly. Emergency locking is a common method for stabilizing and fixing distal radius fractures. Emergency locking (such as external fixators and locking plates) is an important method for early stabilization and fixation of distal radius fractures to help maintain the stability of the distal radius fracture site, promote healing, and reduce the occurrence of complications.

[0003] Emergency locking of distal radius fractures needs to ensure that the locking operation point can effectively fix the distal radius fracture site. During the emergency locking process of distal radius fractures, it is necessary to monitor the placement of the distal radius fracture site and the fixation device to prevent displacement. Accurate positioning of the locking operation point not only affects the healing of the distal radius fracture, but also has a direct impact on the functional recovery of the patient. However, in the prior art, when emergency locking is performed on complex distal radius fractures, the alignment of the locking operation point is difficult due to the shape and angle of the distal radius fracture site, resulting in inaccurate locking position alignment or incorrect alignment angle during the emergency locking operation, that is, there is an alignment error of the locking operation point during the emergency locking operation, resulting in the final locking operation point not meeting the optimal position, thereby affecting the locking effect of the distal radius fracture site, resulting in an increase in the risk of complications after emergency locking and non-union of the distal radius fracture. Therefore, how to perform locking compensation for the alignment process of the locking operation point of the distal radius fracture, thereby reducing the alignment error during the emergency locking process has become a difficult problem faced by the industry.

The emergency locking device for distal radius fractures performs locking coordination information for locking alignment; selects a to-be-locked area as the selected locking area, extracts the fluctuation amount of the posture alignment of each locking paired point in the selected locking area from the locking coordination information, and then determines the locking deviation when the selected locking area is locked according to the fluctuation amount of all posture alignments, and continues to determine the locking deviation when the remaining to-be-locked areas are locked; based on each locking deviation, adjusts the corresponding locking operation point in each to-be-locked area, and the emergency locking device for distal radius fracture performs emergency locking on the distal radius fracture according to the adjusted locking operation point.

[0016] It can be seen that in the present application, the locking deviation of each area to be locked is determined according to the fluctuation amount of all posture alignments when locking, and then the corresponding locking operation point in each area to be locked is adjusted based on each locking deviation, so that the emergency locking device for distal radius fracture performs emergency locking on the distal radius fracture according to the adjusted locking operation point; firstly, the degree of alignment of the locking operation point in the locking pairing point to the simulated locking point is determined by the distance between the locking operation point in the locking pairing point and the simulated locking point (that is, the locking alignment cost of the locking pairing point), so as to understand the alignment error in the posture transformation process during emergency locking, so as to accelerate the precise positioning process during the emergency locking of the distal radius fracture; secondly, the collaborative posture information of the emergency locking device for distal radius fracture determined by all locking alignment costs determines the degree of deviation (that is, posture deviation) of each locking pairing point in each area to be locked when performing posture alignment, so as to understand the emergency locking of the distal radius fracture. The operation error in the locking surgery is then determined according to each posture deviation, and the fluctuation amount of the posture alignment of each locking pairing point in each area to be locked is determined, so that the fluctuation degree of the locking pairing point in the posture deviation can be understood; further, the degree of deviation that needs to be adjusted when the locking operation point position in the area to be locked is performed (i.e., the locking deviation) is determined through the fluctuation amount of all posture alignments, so that the alignment error in the posture transformation of the locking operation point at the distal radius fracture can be compensated during emergency locking; finally, the corresponding locking operation point in each area to be locked is adjusted based on each locking deviation to ensure that the emergency locking device of the distal radius fracture performs emergency locking according to the locking position after compensation of each locking operation point, thereby completing the compensation control of the locking operation point at the distal radius fracture and reducing the alignment error during the emergency locking process; in summary, the scheme can perform locking compensation on the alignment process of the locking operation point of the distal radius fracture, thereby reducing the alignment error during the emergency locking process.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The embodiment of the present application provides an emergency locking device and method for distal radius fracture, the core of which is to simulate the locking of the distal radius fracture to obtain a simulated locking point set at the distal radius fracture; divide the simulated locking point set based on the neighborhood relationship between each simulated locking point in the simulated locking point set to obtain multiple areas to be locked at the distal radius fracture; collect the locking operation point set of the locking operation end during the locking process of the distal radius fracture, align and pair the locking operation point set with the simulated locking point set to obtain multiple locking pairing points, and then determine the locking alignment cost of each locking pairing point in the alignment process, and determine the emergency locking of the distal radius fracture through all the locking alignment costs.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1 , which is an exemplary flow chart of an emergency locking method for distal radius fracture according to some embodiments of the present application. The emergency locking method 100 for distal radius fracture mainly includes the following steps: In step 101, a locking simulation is performed on the distal radius fracture to obtain a set of simulated locking points at the distal radius fracture.

[0022] It should be noted that the locking simulation in this application refers to a series of preparatory work before the locking surgery for the distal radius fracture in an emergency situation. These preparatory work includes the evaluation of the distal radius fracture, the planning and configuration of the locking device, and preoperative preparation and positioning. The purpose of simulated locking is to ensure that the locking operation can be performed quickly and accurately in an emergency situation, thereby maximizing the success rate of the surgery and the recovery effect of the distal radius fracture.

[0023] In specific implementation, the locking simulation of the distal radius fracture is performed to obtain the simulated locking point set of the distal radius fracture. The following methods can be used to achieve this: first, the distal radius fracture of the patient can be scanned by a 3D laser scanner before emergency locking to obtain point cloud data of the distal radius fracture before emergency locking. Secondly, a 3D modeling software (such as MeshLab, CloudCompare, etc.) is used to generate a 3D model image of the distal radius fracture site based on the obtained point cloud data. Then, the relevant doctors or relevant experts can use the above-mentioned point cloud data to simulate the locking point set of the distal radius fracture. The point cloud data determines the simulated locking points at the distal radius fracture, that is, according to the type, location and expected locking device type of the fracture, the key points on the fracture site are identified, and the key points include the stable area of ​​the fracture, the location with good bone, and the location points of other locations suitable for fixation (such as screws or locking plates) (i.e., the expected locking points), and all the simulated locking points are marked in the generated three-dimensional model image. Finally, all the obtained simulated locking points are combined into a set of simulated locking points at the distal radius fracture. In other embodiments, other methods may also be used to achieve this, which is not specifically limited here.

[0024] It should be noted that the simulated locking point set in the present application represents the set of all simulated locking points at the distal radius fracture, wherein the simulated locking point is a point with spatial coordinates, and the simulated locking point in the simulated locking point set represents the point of the desired locking position at the distal radius fracture. In addition, by determining the simulated locking point set, the positioning accuracy during emergency locking of the distal radius fracture can be ensured, which helps to perform accurate locking planning and operation to reduce surgical errors.

[0025] In step 102, the simulated locking point set is divided based on the neighborhood relationship between each simulated locking point in the simulated locking point set to obtain a plurality of to-be-locked areas at the distal radius fracture.

[0026] In some embodiments, the simulated locking point set is divided based on the neighborhood relationship between each simulated locking point in the simulated locking point set to obtain multiple to-be-locked areas at the distal radius fracture, which can be achieved by the following steps: Determine a neighborhood point of each simulated locking point in the simulated locking point set, wherein the neighborhood point reflects a neighborhood relationship between each simulated locking point in the simulated locking point set; For each simulated locking point, all simulated locking points with the same neighborhood point in the simulated locking point set are divided into the same area to be locked, thereby obtaining multiple areas to be locked at the distal radius fracture.

[0027] In specific implementation, determining the neighborhood points of each simulated locking point in the simulated locking point set can be achieved in the following manner, namely: first, a neighborhood threshold can be set according to the density of the simulated locking point set (that is, the distribution density of all simulated locking points in the standard locking posture point set), and the neighborhood threshold is a distance value. The neighborhood threshold is a threshold used to determine the neighborhood points of each simulated locking point in the simulated locking point set. Secondly, a simulated locking point in the simulated locking point set is selected as the selected simulated locking point, and a distance metric standard (such as Euclidean distance, Manhattan distance, etc.) between the selected simulated locking point and the remaining simulated locking points in the simulated locking point set is calculated. , and then, all the simulated locking points in the simulated locking point set whose distance metric standard is less than the neighborhood threshold are used as neighborhood points of the selected simulated locking point. Finally, the neighborhood points of the remaining simulated locking points in the simulated locking point set are continued to be determined. In other embodiments, other methods can also be used for determination, which is not limited here. It should be noted that when the selected simulated locking point in the simulated locking point set can be divided into multiple areas to be locked, the selected simulated locking point and the simulated locking point corresponding to its minimum distance metric standard are finally divided into the same area to be locked. In other embodiments, other methods can also be used for division, which is not limited here.

[0028] It should be noted that in the present application, the distance measurement standard corresponding to the neighborhood point can be used to analyze the distance relationship between the selected simulated locking point and other simulated locking points. Therefore, the neighborhood point can reflect the neighborhood relationship between each simulated locking point in the simulated locking point set; in addition, the area to be locked represents a specific area of ​​the distal radius fracture where an emergency locking operation needs to be performed. By determining the area to be locked, stable fixation of the distal radius fracture can be ensured.

[0029] In step 103, the locking operation point set of the locking operation end during the locking process of the distal radius fracture is collected, and the locking operation point set is aligned and paired with the simulated locking point set to obtain multiple locking pairing points, and then the locking alignment cost of each locking pairing point in the alignment process is determined, and the locking coordination information of the emergency locking device for the distal radius fracture for locking alignment is determined through all the locking alignment costs.

[0030] It should be noted that the locking operation end in the present application refers to the part or tool that specifically performs the locking operation during the locking surgery of the distal radius fracture. The locking operation end is the key interface in the locking process, and is responsible for firmly fixing the locking device (such as locking nails, locking plates, locking drills, etc.) to the bone to achieve stable fixation of the distal radius fracture; in specific implementation, the locking operation point set of the locking operation end during the locking process of the distal radius fracture can be collected in the following manner, namely: a three-dimensional laser scanner can be used to scan the patient's distal radius fracture in real time during the emergency locking operation to obtain the locking operation points of the locking operation end at the distal radius fracture during the locking process, and record the current spatial coordinates of each locking operation point and the spatial coordinates of the spatial position point to which each locking operation point will eventually reach, and then all the locking operation points are combined into a locking operation point set of the locking operation end during the locking process of the distal radius fracture. In other embodiments, other methods can also be used for collection, which is not specifically limited here.

[0031] It should be noted that the locking operation point set represents the set of all locking operation points of the locking operation end at the distal radius fracture during the locking process. The locking operation points in the locking operation point set are points with spatial coordinates, and the locking operation points reflect the locking positions of the actual emergency locking operations on the distal radius fracture.

[0032] In some embodiments, reference Figure 2 As shown, this figure is an exemplary flow chart for determining locking pairing points in some embodiments of the present application. In this embodiment, the locking operation point set is aligned and paired with the simulated locking point set to obtain multiple locking pairing points, which can be achieved by the following steps: First, in step 1031, the spatial coordinates of each simulated locking point in the simulated locking point set are obtained; Next, in step 1032, the target alignment position of each locking operation point in the locking operation point set is determined; Finally, in step 1033, the locking operation point set is paired with the simulated locking point set based on all target alignment positions and all spatial coordinates to obtain a plurality of locking pairing points.

[0033] In specific implementation, determining the target alignment position of each locking operation point in the locking operation point set can be achieved in the following manner, namely: the spatial position point that each locking operation point in the locking operation point set ultimately wants to reach can be corresponded as the target alignment position of each locking operation point; based on all target alignment positions and all spatial coordinates, the locking operation point set is point-paired with the simulated locking point set to obtain multiple locking pairing points, which can be achieved in the following manner, namely: the locking operation point with the same spatial coordinates of the target alignment position of the locking operation point in the locking operation point set as the spatial coordinates of the simulated locking point in the simulated locking point set is paired with the simulated locking point as one locking pairing point, thereby obtaining multiple locking pairing points. In other embodiments, other methods can also be used for point pairing, which is not limited here; it should be noted that the locking pairing point represents a combined point formed by pairing the simulated locking point in the simulated locking point set with the locking operation point in the locking operation point set.

[0034] It should be noted that the alignment pairing in the present application refers to the process of pairing the locking operation point set with the simulated locking point set through the target alignment position of each locking operation point in the locking operation point set and the spatial coordinates of each simulated locking point to obtain multiple locking pairing points. The alignment pairing can ensure the accuracy of the locking position, thereby reducing the risk of failure of emergency locking surgery for distal radius fractures.

[0035] In some embodiments, the locking alignment cost of each locking pairing point in the alignment process is determined, that is: first, a locking pairing point is selected as the selected locking pairing point, and the Euclidean distance between the simulated locking point and the locking operation point in the selected locking pairing point can be calculated through the numpy library in Python, and then the Euclidean distance is used as the alignment distance of the selected locking pairing point, and the alignment distance represents the distance between the locking operation point and the simulated locking point in the locking pairing point; secondly, the existing alignment transformation model (such as rigid transformation, affine transformation, etc.) is used according to the spatial coordinates of the locking operation point in the selected locking pairing point and the spatial coordinates of the simulated locking point and the selected The alignment distance is used to determine the transformation coefficient of the locking operation point in the selected locking pairing point to be aligned to the simulated locking point (the transformation coefficient includes: rotation angle, translation vector, scaling factor, etc.), and then, by using machine learning and deep learning technology, the alignment error when the locking operation point in the selected locking pairing point is aligned to the simulated locking point for posture alignment is estimated based on the transformation coefficient, and then the estimated result is used as the locking alignment cost of the selected locking pairing point in the alignment process, and finally, the locking alignment cost of the remaining locking pairing points in the alignment process is continued to be determined. In other embodiments, other methods can also be used for determination, which is not limited here.

[0036] It should be noted that the locking alignment cost in the present application reflects the degree of alignment of the locking operation point in the locking pairing point to the simulated locking point. The larger the locking alignment cost, the worse the degree of alignment of the locking operation point in the locking pairing point to the simulated locking point. The smaller the locking alignment cost, the better the degree of alignment of the locking operation point in the locking pairing point to the simulated locking point. In addition, by determining the locking alignment cost, the alignment error in the posture transformation process during emergency locking can be understood, so as to accelerate the precise positioning process during the emergency locking process of distal radius fractures and make the emergency locking process more efficient. It will not be repeated here.

[0037] In some embodiments, the following steps may be used to determine the locking coordination information of the emergency locking device for locking alignment of the distal radius fracture through all locking alignment costs: Obtaining the locking operation point set and the simulated locking point set at the distal radius fracture; Determine a mapping transformation matrix between the locking operation point set and the simulated locking point set based on all locking alignment costs; Determining the collaborative posture relationship between the locking operation point set and the simulated locking point set through the mapping transformation matrix; The collaborative posture relationship is used as locking collaborative information for locking and aligning an emergency locking device for distal radius fracture.

[0038] In specific implementation, determining the mapping transformation matrix between the locking operation point set and the simulated locking point set by all the locking alignment costs can be implemented in the following manner, namely: the rigid or affine transformation matrix between each locking operation point in the locking operation point set and each simulated locking point in the simulated locking point set can be determined based on all locking paired points between the locking operation point set and the simulated locking point set and the locking alignment cost of each locking paired point by a least squares fitting algorithm, and then the obtained matrix is ​​used as the mapping transformation matrix between the locking operation point set and the simulated locking point set. In other embodiments, other methods can also be used for determination, which is not limited here.

[0039] It should be noted that the mapping transformation matrix represents the rotation and displacement information of the posture transformation of each locking operation point in the locking operation point set to the corresponding each simulated locking point in the simulated locking point set. Determining the mapping transformation matrix can understand the position information of transforming the locking operation point set to the simulated locking point set so that the actual locking point is aligned with the ideal locking point. By obtaining the mapping transformation matrix, the precise alignment of the locking operation point set and the simulated locking point set can be achieved, which will not be repeated here.

[0040] In specific implementation, the collaborative posture relationship between the locking operation point set and the simulated locking point set can be determined by the mapping transformation matrix in the following manner, namely: first, the mapping transformation matrix can be used to solve the required rotation matrix and translation vector corresponding to the spatial position of each locking operation point in the locking operation point set when it is transformed to the corresponding simulated locking point in the simulated locking point set; secondly, the rotation matrix and translation vector corresponding to the transformation of each locking operation point are adjusted by an optimization algorithm (such as gradient descent, Newton's method or genetic algorithm) to obtain all optimized transformation parameters, and the transformation parameters include the optimized rotation matrix and the optimized translation vector; finally, all the optimized transformation parameters are used as the collaborative posture relationship between the locking operation point set and the simulated locking point set, and then the collaborative posture relationship is used as the locking collaborative information for locking and alignment of the emergency locking device for distal radius fractures; other methods may also be used for determination in other embodiments, which are not limited here.

[0041] It should be noted that the locking coordination information in the present application represents a set of transformation parameters when the spatial position of each locking operation point in the emergency locking device for distal radius fracture is transformed to the spatial position of the corresponding simulated locking point (the transformation parameters include: rotation matrix and translation vector). In addition, by determining the locking coordination information for locking alignment of the emergency locking device for distal radius fracture, the locking alignment cost between the locking operation point set and the simulated locking point set can be reduced, thereby optimizing the effect and accuracy of the emergency locking process.

[0042] In step 104, a to-be-locked area is selected as the selected locking area, and the fluctuation amount of the posture alignment of each locking paired point in the selected locking area is extracted from the locking coordination information, and then the locking deviation degree of the selected locking area when locking is determined according to the fluctuation amount of all posture alignments, and the locking deviation degree of the remaining to-be-locked areas when locking is further determined.

[0043] In some embodiments, extracting the fluctuation amount of the posture alignment of each locking pairing point in the selected locking area from the locking coordination information can be achieved by the following steps: Performing posture alignment association on the selected locking area based on the locking coordination information to obtain the posture deviation of each locking pairing point in the selected locking area; The fluctuation amount of the posture alignment of each locking pairing point in the selected locking area is determined by each posture deviation.

[0044] Wherein, in some embodiments, reference Figure 3 As shown, this figure is an exemplary flow chart for determining posture deviation in some embodiments of the present application. In this embodiment, posture alignment association is performed on the selected locking area based on the locking cooperation information, and the posture deviation of each locking pairing point in the selected locking area can be obtained by the following steps: First, in step 1041, each locking operation point in the locking operation point set is obtained; Next, in step 1042, the alignment position of each locking operation point in the locking operation point set after posture transformation is determined according to the locking coordination information; Finally, in step 1043, each alignment position is associated with the selected locking area to obtain the posture deviation of each locking pairing point in the selected locking area.

[0045] In specific implementation, the alignment position in the present application represents the coordinate position of each locking operation point in the locking operation point set after the posture transformation. The alignment position of each locking operation point in the locking operation point set after the posture transformation determined by the locking cooperation information can be implemented in the following manner, namely: the alignment position of each locking operation point in the locking operation point set after the posture transformation can be determined by the rotation matrix and translation vector corresponding to each locking operation point in the locking cooperation information and the spatial coordinates of each locking operation point. Each alignment position corresponds to the coordinates of each locking operation point after the posture transformation. The process of determining the alignment position is, for example: for each locking operation point, multiply the spatial coordinates of the locking operation point by the rotation matrix corresponding to the locking operation point, and then add the translation vector corresponding to the locking operation point. The final spatial coordinates are the alignment positions of the locking operation points. Other methods may also be used to determine the alignment position in other embodiments, which are not limited here.

[0046] In specific implementation, each alignment position is associated with the selected locking area to obtain the posture deviation of each locking pairing point in the selected locking area, which can be achieved in the following manner, namely: first, a locking pairing point in the selected locking area is selected, and then the alignment position of the locking operation point in the locking pairing point and the spatial coordinates of the simulated locking point in the locking pairing point are obtained. Then, the alignment position of the locking operation point and the spatial coordinates of the simulated locking point are aligned. That is, the Euclidean distance between the spatial coordinates corresponding to the alignment position of the locking operation point and the spatial coordinates of the simulated locking point is used as the posture deviation of the locking pairing point. The posture alignment process is the posture association process. Finally, the posture deviations of the remaining locking pairing points in the selected locking area are continued to be determined. Other methods can also be used for determination in other embodiments, which are not limited here.

[0047] It should be noted that the posture alignment association in the present application refers to the process of determining the alignment position of each locking operation point in the locking operation point set after the posture transformation based on the locking coordination information, and then aligning the coordinate position (i.e., the alignment position) of each locking operation point in the locking operation point set after the posture transformation with the spatial coordinates of the corresponding simulated locking point, thereby obtaining the posture deviation of each locking paired point in the area to be locked. In addition, by determining the posture deviation of each locking paired point in the area to be locked through the posture alignment association, the alignment error in the emergency locking process can be understood, so as to formulate an effective locking compensation strategy, thereby improving the accuracy of the emergency locking operation.

[0048] It should be noted that the posture deviation in the present application reflects the degree of deviation when aligning the posture of each locking pairing point in the locking area. The larger the posture deviation, the greater the degree of deviation when aligning the posture of each locking pairing point in the locking area. Conversely, the smaller the posture deviation, the smaller the degree of deviation when aligning the posture of each locking pairing point in the locking area. It will not be repeated here.

[0049] In some embodiments, determining the fluctuation amount of the posture alignment of each locking pairing point in the selected locking area from each posture deviation can be achieved by using the following steps: To determine the postural alignment threshold for emergency locking of distal radius fractures; The fluctuation amount of the posture alignment of each locking paired point in the selected locking area is determined according to the posture alignment threshold and each posture deviation.

[0050] In specific implementation, the posture alignment threshold is a threshold used to judge the degree of posture deviation of the to-be-locked area at the distal radius fracture during the posture transformation process during emergency locking. The posture alignment threshold can effectively judge the alignment accuracy of the locking operation point in the to-be-locked area to the simulated locking point; the determination of the posture alignment threshold during emergency locking of the distal radius fracture can be achieved in the following manner, namely: first, determine the allowable alignment error value of each to-be-locked area at the distal radius fracture, namely: for each to-be-locked area, obtain the posture deviation of each locking pairing point in the to-be-locked area, calculate the average and standard deviation of all posture deviations in the to-be-locked area, and then compare the mean with the standard The sum of k times of the difference is used as the allowable value of alignment error when the area to be locked is subjected to posture alignment, thereby obtaining the allowable value of alignment error of each area to be locked at the distal radius fracture. The allowable value of alignment error represents the value of the allowable alignment error range when the area to be locked is subjected to posture alignment, wherein k is a constant, and the value of k is usually between 1.5 and 2. The value of k depends on the application requirements and the allowable error range. In this embodiment, k is taken as 1.5. Finally, the average value of the allowable values ​​of alignment errors of all areas to be locked is used as the posture alignment threshold for emergency locking of the distal radius fracture. Other methods may also be used for determination in other embodiments, which are not limited here.

[0051] In specific implementation, the fluctuation amount of the posture alignment of each locking pairing point in the selected locking area can be determined according to the posture alignment threshold and each posture deviation in the following manner, namely: a locking pairing point is selected from the selected locking area as the selected locking pairing point, and the posture deviation of the simulated locking point and the locking operation point in the selected locking pairing point during posture alignment is obtained, and then the absolute value of the difference between the posture deviation and the posture alignment threshold is used as the fluctuation amount of the posture alignment of the selected locking pairing point, and the fluctuation amount of the posture alignment of the remaining locking pairing points in the selected locking area is continued to be determined. In other embodiments, other methods can also be used for determination, which is not limited here.

[0052] It should be noted that the fluctuation amount in the present application reflects the degree of fluctuation of the locking pairing point in the posture deviation. The larger the fluctuation amount, the greater the degree of fluctuation of the locking pairing point in the posture deviation. Conversely, the smaller the fluctuation amount, the smaller the degree of fluctuation of the locking pairing point in the posture deviation. In addition, the fluctuation amount quantifies the stability of the posture alignment of the locking operation point in the emergency locking of the distal radius fracture. By determining the fluctuation amount, the degree of operational error in the emergency locking operation can be understood, thereby improving the stability and effect of the emergency locking of the distal radius fracture. It will not be repeated here.

[0053] In some embodiments, determining the locking deviation of the selected locking area for locking according to the fluctuation amount of all posture alignments can be implemented by the following steps: Determine the compensation adjustment factor when performing locking compensation in the selected locking area; Obtain the fluctuation amount corresponding to all locking pairing points in the selected locking area; The locking deviation when locking the selected locking area is determined by the fluctuation amount of all posture alignments and the compensation adjustment factor.

[0054] It should be noted that the compensation adjustment factor is used to adjust the degree of locking compensation control of the locking area during emergency locking. By determining the compensation adjustment factor, the instability caused by excessive or insufficient compensation can be reduced, thereby improving the stability and reliability of locking compensation during emergency locking. In specific implementation, the compensation adjustment factor for locking compensation in the selected locking area can be determined in the following way, namely: the degree of locking compensation required for the selected locking area during the locking process of the distal radius fracture can be evaluated by using regression analysis, statistical analysis or machine learning models based on the experience of relevant experts and the fluctuation amount of posture alignment in historical experiments. The result of the evaluation is used as the compensation adjustment factor for locking compensation in the selected locking area. The compensation adjustment factor is usually 1 or other values. The compensation adjustment factor can be adjusted according to the needs of the application scenario so that the compensation adjustment factor can effectively improve the alignment accuracy in the actual operation of emergency locking. In other embodiments, other methods can also be used for determination, which is not limited here.

[0055] In specific implementation, the locking deviation degree of the selected locking area when locking is determined by the fluctuation amount of all posture alignments and the compensation adjustment factor can be achieved in the following way, namely: calculating the standard deviation of the fluctuation amount of all posture alignments in the selected locking area, and then taking the product of the calculated standard deviation and the compensation adjustment factor as the locking deviation degree of the selected locking area when performing emergency locking. In other embodiments, other methods can also be used for determination, which is not limited here.

[0056] It should be noted that the locking deviation in the present application reflects the degree of deviation that needs to be adjusted when the posture alignment of the locking operation point position in the locking area is performed. The higher the locking deviation, the greater the degree of deviation that needs to be adjusted when the posture alignment of the locking operation point position in the locking area is performed. Conversely, the lower the locking deviation, the smaller the degree of deviation that needs to be adjusted when the posture alignment of the locking operation point position in the locking area is performed. Therefore, by determining the locking deviation, the alignment error in the posture transformation of the locking operation point at the distal radius fracture can be compensated during emergency locking, which will not be repeated here.

[0057] In step 105, the corresponding locking operation point in each area to be locked is adjusted based on each locking deviation, and the emergency locking device for the distal radius fracture performs emergency locking on the distal radius fracture according to the adjusted locking operation point.

[0058] In some embodiments, adjusting the corresponding locking operation point in each to-be-locked area based on each locking deviation can be achieved by using the following steps: Obtaining the actual position of the corresponding locking operation point in each area to be locked; Obtain the locking deviation of each area to be locked when locking; The actual position of each locking operation point in the corresponding to-be-locked area is compensated by each locking deviation, so as to obtain the compensated locking position of each locking operation point.

[0059] In specific implementation, the actual position of the corresponding locking operation point in each area to be locked is obtained, that is: the current spatial coordinates of each locking operation point in the locking operation point set can be used as the actual position of the corresponding locking operation point in each area to be locked; the actual position of each locking operation point in the corresponding area to be locked is compensated by each locking deviation, and the compensated locking position of each locking operation point can be obtained. It can be implemented in the following way, that is: a compensation control model for emergency locking of distal radius fracture can be established based on the actual positions of all locking operation points in historical experimental data and the corresponding locking deviations through linear regression, support vector machine, neural network and other algorithms. The compensation control model is used to compensate and adjust the position of the locking operation point during emergency locking of distal radius fracture. A model, wherein the input of the compensation control model is the actual position of each locking operation point and the locking deviation of the to-be-locked area corresponding to each locking operation point, and the output of the compensation control model is the spatial coordinates of the locked position of each locking operation point after compensation, and then the actual position of each locking operation point in the locking operation point set and the corresponding locking deviation are input into the compensation control model, so as to obtain the spatial coordinates of the locked position of each locking operation point after compensation; the spatial coordinates of the compensated locking position are input into the control interface of the emergency locking device for distal radius fracture, so as to ensure that the emergency locking device for distal radius fracture performs emergency locking according to the compensated locking positions of each locking operation point, thereby completing the compensation control of the locking operation points at the distal radius fracture.
