Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a method and device for generating an electronic prescription for a Taylor space stent. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The Taylor space stent is an external fixator commonly used in fields such as limb deformity correction and fracture treatment. It usually includes a proximal ring, a distal ring, an extension rod, a steel needle and a steel needle fixing seat. The proximal ring and the distal ring are both metal rings with round holes; one end of the retractable extension rod is hinged to the proximal ring through a universal joint, and the other end is hinged to the distal ring through a universal joint.

[0004] Taylor space stents include standard Taylor space stents, which are fixed in relative position, and non-standard Taylor space stents for special situations. Standard Taylor space stents are characterized by circular proximal and distal rings of equal size, and typically have six extension rods, all of which are in use. Non-standard Taylor space stents are primarily used to address special circumstances. For example, when the deformity of the affected limb is severe and difficult to fit using a standard Taylor space stent, one of the proximal or distal rings may be replaced with an elliptical shape. Alternatively, the number of extension rods may be reduced or increased, such as from six to five or seven, to accommodate complex deformities. For standard Taylor stents, existing prescription generation methods use X-ray images to obtain input information such as patient deformity parameters, stent parameters, and installation parameters. Computer software then generates a plan to guide Taylor space stent adjustment, including information such as the length of the extension rods required for daily adjustment. However, existing patient deformity parameters require a combination of imaging or clinical measurements. Based on the deformity parameters, the frame's dimensional parameters, and the original installation parameters, the required adjustment for each extension rod is deduced to restore the stent to the target position. This process requires combining multiple input data for calculation. If any of the input data, such as deformity parameters or installation parameters, is inaccurate, the accuracy of the prescription will be affected, and thus the treatment effect. Moreover, this method is obviously only applicable to standard Taylor space stents. For special cases with non-standard Taylor space stents, it is impossible to accurately and effectively prescribe. Summary of the Invention

[0005] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a method and device for generating an electronic prescription for a Taylor space stent, which can achieve accurate calculation of the target adjustment amount of each extension rod in the Taylor space stent without relying on the parameters of the stent and the deformity parameters of the fracture, thereby ensuring the treatment effect. Moreover, the method is applicable to both standard Taylor space stents and non-standard Taylor space stents under special circumstances.

[0017] The proximal fixed ring model of the aligned standard model is bound to the proximal broken bone model, and the distal fixed ring model is bound to the distal broken bone model to obtain the proximal combined model and the distal combined model respectively. After performing virtual reset, the length of each connecting rod in the reset state of the standard model is obtained, that is, the target length.

[0018] In some embodiments, after obtaining the standard model, the connection points between each extension rod and the proximal fixing ring model and the distal fixing ring model in the standard model are also identified, and the original length and target length of the extension rod are calculated based on the corresponding connection point positions of each extension rod before and after the virtual reset is performed.

[0019] In some embodiments, the proximal combined model and the distal combined model are matched using the following method:

Through virtual resetting, the target adjustment amount of each extension rod in the Taylor space bracket is calculated intuitively and efficiently, thereby improving the calculation accuracy and ensuring the treatment effect. In addition, since it is not necessary to obtain the parameters of the bracket when calculating the length of each extension rod, the above method is not only applicable to standard Taylor structures, but also to non-standard Taylor or Taylor-like structures, and there are no standardized requirements for installation. Even if the long axis of the bone is not at the center of the fixed ring or is not perpendicular to the plane of the fixed ring, the target adjustment amount of each extension rod can be accurately calculated.

The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute improper limitations on the present invention.

[0039] Figure 1 This is a flow chart of a method for generating an electronic prescription for a Taylor space stent according to an embodiment of the present invention;

[0040] Figure 2 This is a framework diagram of an electronic prescription generation device for a Taylor space stent in an embodiment of the present invention. DETAILED DESCRIPTION

[0041] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although certain embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Instead, these embodiments are provided to provide a more thorough and complete understanding of the present application. It should be understood that the drawings and embodiments of the present application are for illustrative purposes only and are not intended to limit the scope of protection of the present application.

[0042] In the description of the embodiments of the present application, the term “including” and similar terms should be understood as open inclusion, that is, “including but not limited to.” The term “based on” should be understood as “at least partially based on.”

[0043] One or more embodiments of the present invention provide a method for generating an electronic prescription for a Taylor space stent, such as Figure 1 As shown, the following steps are included:

[0044] Step 1: Obtain imaging data of the affected limb with a Taylor space brace;

[0045] Step 2: Modeling and segmenting the affected limb image data to obtain a distal fracture model, a proximal fracture model, and a Taylor space stent model;

[0046] Step 3: Obtain the length of each extension rod of the Taylor space bracket model in the current state, that is, the original length;

[0047] Step 4: Bind the proximal fixation ring model to the proximal fractured bone model, and bind the distal fixation ring model to the distal fractured bone model to obtain the proximal combined model and the distal combined model respectively;

[0048] Step 5: Positionally adjust the proximal combined model and the distal combined model to achieve virtual resetting between the proximal fractured bone model and the distal fractured bone model, and obtain the lengths of the extension rods of the Taylor space stent model in the resetting state, i.e., the target lengths;

[0049] Step 6: Generate an electronic prescription based on the original length and target length of each extension rod.

[0050] The above method can directly obtain the target length of each extension rod through virtual resetting, and then calculate the target adjustment amount, avoiding the process of obtaining deformity parameters through imaging or measurement, and combining the stent parameters for calculation to deduce the target adjustment amount of the extension rod. It also avoids the disadvantage of affecting the treatment effect due to inaccurate input parameters, and improves the reliability of electronic prescriptions.

[0051] In addition, since the parameters of the bracket do not need to be obtained when calculating the length of each extension rod, the above method can be used not only for standard Taylor frames but also for non-standard Taylor structures. Moreover, there are no standardized requirements for installation. Even if the long axis of the bone is not at the center of the fixed ring or is not perpendicular to the plane of the fixed ring, the target adjustment amount of each extension rod can be accurately calculated.

[0052] In step 1, the image data is a CT scan image, which can be obtained by a CT scanner. After obtaining the image data of the affected limb with the Taylor space stent, artifact processing is also performed. Specifically, filtering, such as a median filter, a Gaussian filter, etc., and / or threshold segmentation can be used to distinguish metal signals from tissue signals, and metal signals exceeding a threshold are processed.

[0053] In step 2, the modeling can be performed using digital medical modeling software or directly by segmentation modeling on a CT machine.

[0054] In step 3 and step 5, as a specific implementation method for obtaining the length of the extension rod, in step 3, the connection points of each extension rod with the proximal fixed ring model and the distal fixed ring model in the Taylor space stent model are identified, and the original length of the extension rod is calculated based on the position of the connection point corresponding to each extension rod. In step 5, after performing the virtual reset, the target length of the extension rod is also calculated based on the position of the connection point corresponding to each extension rod. It can be understood that the above-mentioned original length and target length can be measured manually in the software, or they can be automatically calculated by a computer program based on the position of each connection point.

[0055] By using the above method, it is only necessary to obtain the connection points of each extension rod with the proximal ring and the distal ring to accurately calculate the length of the extension rod, without the need to locate the position of each extension rod.

[0056] Since metal artifacts will be present when imaging the Taylor space stent, in order to avoid the influence of metal artifacts on the model, ensure the calculation accuracy of the extension rod length, and also to facilitate the calculation, as another specific implementation method, a standard model library is pre-established, and the standard model library includes standard models of Taylor space stents of different manufacturers and models. In step 3, a standard model identical to the Taylor space stent is obtained; with the proximal and distal fixing rings of the Taylor space stent as a reference, the standard model is aligned to the Taylor space stent model so that the proximal and distal fixing rings of the two overlap, and the length of each connecting rod in the current state of the standard model, that is, the original length, is obtained. In step 4, the proximal fixing ring model of the aligned standard model is bound to the proximal broken bone model, and the distal fixing ring model is bound to the distal broken bone model to obtain a proximal combined model and a distal combined model respectively; in step 5, after performing virtual reset, the length of each connecting rod in the reset state of the standard model, that is, the target length, is obtained.

[0057] Using the standard model as a bridge, we first matched it to the external fixator model in its original state before reduction to obtain the original length of each extension rod of the Taylor space external fixator before reduction; then we bound the standard model to the broken bone model, performed virtual reduction, and obtained the target length of each extension rod after reduction in the virtual reduction state, thus solving the problem of inaccurate calculation caused by metal artifacts.

[0058] Specifically, after obtaining the standard model, the connection points of each extension rod in the standard model with the proximal fixed ring model and the distal fixed ring model are also identified, and the original length and target length of the extension rod are calculated based on the corresponding connection point positions of each extension rod before and after the virtual reset. As another calculation method, a standard model parameter table can also be pre-stored, and the standard model parameter table includes identification information of each standard model (such as the corresponding bracket manufacturer and model), as well as the initial length of each extension rod in the standard model. When the standard model is aligned to the Taylor space bracket model in step 3, the matching transformation parameters of the standard model are obtained. Based on the matching transformation parameters and the initial length of each extension rod in the standard model, the length of each extension rod in the current state, that is, the original length, is obtained. In step 4, when performing the virtual reset, the reset transformation parameters of the standard model are obtained, and the length of each extension rod after reset, that is, the target length, is calculated based on the reset transformation parameters.

[0059] In step 5, for general fractures, the position adjustment can be automatically achieved based on the cross-sections of the distal fracture and the proximal fracture, and the fracture cross-sections of the distal fracture model and the proximal fracture model are aligned to achieve virtual reduction; it can also be achieved manually by using three-dimensional modeling software to perform manual dragging, rotation and other operations on the distal bone copy model to splice the cross-sections of the distal fracture model and the proximal fracture model.

[0060] As another implementation, imaging data of the patient's unaffected limb is obtained, and three-dimensional reconstruction is performed based on the imaging data to obtain a bone model of the unaffected limb. Virtual reduction is achieved by aligning the proximal and distal combined models with the mirror image model of the unaffected limb. Those skilled in the art will appreciate that if the cross-sections of the proximal or distal bones are comminuted, virtual reduction based on cross-section splicing is difficult. In this case, obtaining imaging data of the unaffected limb is preferred.

[0061] For limb correction, the doctor needs to determine the target position for adjustment to achieve virtual resetting. In step 6, based on the original length and target length of each extension rod, the electronic prescription is generated, which specifically includes:

[0062] (1) Calculating the target adjustment amount of each extension rod based on the original length and target length of each extension rod;

[0063] (2) Obtain the maximum target adjustment amount, and calculate the number of days required to reach the maximum target adjustment amount based on the set daily adjustment amount (usually within 1 mm);

[0064] (3) decomposing the target adjustment amount of each extension rod according to the number of days to obtain the daily adjustment amount of each extension rod;

[0065] (4) Generate an electronic prescription based on the daily adjustment amount of each extension rod.

[0066] Based on the above electronic prescription, simultaneous correction of multiple planes can be achieved.

[0067] In clinical application, after the Taylor space stent is installed for the user and an electronic prescription is issued, the user usually adjusts it daily according to the electronic prescription. However, the target adjustment amount of each extension rod sometimes varies greatly. The target adjustment amount of some extension rods is very small. For example, a total of 3mm needs to be adjusted. If it is broken down into 100 days, only 0.03mm needs to be adjusted every day. For the user, the smaller the adjustment amount, the more difficult it is to control the accuracy. Moreover, it may happen that the user forgets to adjust it one day, resulting in failure to strictly follow the prescription requirements. The longer the time, the greater the cumulative error. Based on this, in step (4), the stages are divided according to the required number of days to obtain the staged adjustment target and generate a staged electronic prescription. The staged electronic prescription includes the daily adjustment amount and review time of each extension rod within the time corresponding to the stage. When the patient goes to the hospital for a review according to the review time, the doctor can determine whether the adjustment is carried out according to the prescription based on the length of each extension rod, so as to facilitate timely intervention.

[0068] In order to avoid problems such as forgetfulness and inaccurate manual adjustment, the Taylor space support is electric and also includes a drive motor and a control module. The control module can establish a connection with the user terminal via a wireless network. As a specific implementation form, the electric Taylor space support can adopt the form disclosed in patent document CN206381227U. After the electronic prescription is generated, it is sent to the user terminal. After the user terminal establishes a connection with the electric Taylor space support, it makes adjustments based on the daily adjustment amount in the electronic prescription.

[0069] On this basis, in order to reduce the patient's pain during daily adjustment, the electronic prescription also includes the number of daily adjustments (for example, 3 times), the time of each adjustment and the amount of each adjustment, so that the electric Taylor space bracket is adjusted according to the set time, and the daily adjustment amount is divided into multiple executions, which can significantly reduce the patient's pain and achieve non-sensory adjustment.
