Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical device technology, and in particular relates to a method and apparatus for generating electronic prescriptions for a Taylor space stent. Background Technology
[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.
[0003] The Taylor space frame is an external fixation device commonly used in limb deformity correction and fracture treatment. It typically includes a proximal ring, a distal ring, an extension rod, steel pins, and a steel pin fixation seat. Both the proximal and distal rings are metal rings with round holes. One end of the telescopic extension rod is hinged to the proximal ring via a universal joint, and the other end is hinged to the distal ring via a universal joint.
[0004] Taylor space stents include standard Taylor space stents with fixed relative positions and non-standard Taylor space stents for special cases. Standard Taylor space stents are characterized by circular and equal-sized proximal and distal rings, and typically have six extension rods, all of which are in use. Non-standard Taylor space stents are mainly used for special cases, such as when the limb deformity is severe and a standard Taylor space stent is difficult to fit. In such cases, one of the proximal or distal rings may be replaced with an elliptical one. Alternatively, the number of extension rods may be reduced or increased, for example, changing from a 6-axis to a 5-axis or 7-axis stent to address complex deformities. For standard Taylor stents, existing prescription generation methods involve obtaining input information such as patient deformity parameters, stent parameters, and installation parameters from X-ray images. Computer software is then used to generate a plan to guide Taylor space stent adjustments, such as the daily adjustment length of the extension rods. However, current methods require combining patient deformity parameters with imaging or clinical measurements. Based on these deformity parameters, as well as the frame's dimensions and the initial installation parameters, the required adjustment amount for each extension rod when repositioned to the target position is calculated. This process requires calculations based on a combination of various input data. If any one of these input data points, such as malformation or installation parameters, is inaccurate, it will affect the accuracy of the prescription and consequently the treatment outcome. Furthermore, this method is clearly only applicable to standard Taylor space stents; it cannot produce accurate and effective prescriptions for non-standard Taylor space stents in special circumstances. Summary of the Invention
[0005] To overcome the shortcomings of the prior art, the present invention provides an electronic prescription generation method and device for a Taylor space stent, which can accurately calculate the target adjustment amount of each extension rod in the Taylor space stent without relying on the stent parameters or fracture deformity parameters, thus ensuring the treatment effect. Moreover, it is applicable to both standard Taylor space stents and non-standard Taylor space stents under special circumstances.
[0006] To achieve the above objectives, a first aspect of the present invention provides a method for generating an electronic prescription for a Taylor space stent, comprising the following steps:

[0015] In some embodiments, after obtaining the Taylor space scaffold model, a standard model identical to the Taylor space scaffold is obtained from the standard model library;
[0016] Using the proximal and distal fixing rings of the Taylor space scaffold as a reference, the standard model is registered to the Taylor space scaffold model to obtain the length of each connecting rod in the current state of the standard model, i.e., the original length.
[0017] The proximal fixation ring model of the registered standard model is bound to the proximal fracture model, and the distal fixation ring model is bound to the distal fracture 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 in the standard model and the proximal and distal fixed ring models are identified, and the original length and target length of the extension rod are calculated based on the connection point positions of each extension rod before and after the virtual reset is performed.
[0019] In some embodiments, the following method is used to match the proximal combination model and the distal combination model:
[0020] Virtual reduction is achieved by registering the fracture surfaces of the distal and proximal fracture models; or, by acquiring image data of the patient's unaffected limb, performing modeling and segmentation based on the unaffected limb image data to obtain the unaffected bone model, and then performing a mirror operation to obtain a mirror model of the unaffected limb; virtual reduction is achieved by registering the proximal combined model and the distal combined model with the mirror model of the unaffected limb.
[0021] In some embodiments, generating an electronic prescription based on the original length and target length of each extension rod includes:
[0022] Calculate the target adjustment amount for each extension rod based on its original length and target length.
[0023] 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;
[0024] The target adjustment amount for each extension rod is decomposed according to the number of days to obtain the daily adjustment amount for each extension rod;
[0025] An electronic prescription is generated based on the daily adjustment amount for each extension bar; the electronic prescription includes:
[0026] Daily adjustment amount for each extension bar; or,
[0027] The daily adjustment amount and follow-up examination time for each extension bar during a treatment phase; or,
[0028] Number of adjustments per day, duration of each adjustment, and amount of each adjustment.
[0029] A second aspect of the present invention provides an electronic prescription generation apparatus for a Taylor space stent, comprising:
[0030] The image data acquisition module is configured to acquire image data of the affected limb with a Taylor space scaffold;
[0031] The three-dimensional model acquisition module is configured to perform modeling and segmentation based on the image data of the affected limb to obtain a distal fracture model, a proximal fracture model, and a Taylor space scaffold model.

[0036] A fourth aspect of the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method.
[0037] One or more of the above technical solutions do not rely on the parameters of the scaffold or the deformity parameters of the fracture. Through virtual reduction, they can intuitively and efficiently calculate the target adjustment amount of each extension rod in the Taylor space scaffold, improving calculation accuracy and ensuring treatment effectiveness. Furthermore, since calculating the length of each extension rod does not require obtaining the scaffold parameters, the above methods are applicable not only to standard Taylor structures but also to non-standard Taylor or Taylor-like structures. There are no standardized requirements for installation; even if the long axis of the bone is not at the center of the fixation ring or is not perpendicular to the plane of the fixation ring, the target adjustment amount of each extension rod can still be accurately calculated.

[0040] Figure 2 This is a frame diagram of the electronic prescription generation device for the Taylor space stent in an embodiment of the present invention. Detailed Implementation
[0041] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While some embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this application. It should be understood that the drawings and embodiments of this application are for illustrative purposes only and are not intended to limit the scope of protection of this application.
[0042] In the description of the embodiments of this application, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "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, it includes the following steps:
[0044] Step 1: Acquire imaging data of the affected limb with Taylor space brace;
[0045] Step 2: Based on the image data of the affected limb, perform modeling and segmentation to obtain the distal fracture model, the proximal fracture model, and the Taylor space scaffold model;
[0046] Step 3: Obtain the lengths of each extension rod of the Taylor space support model in its current state, i.e., the original lengths;
[0047] Step 4: Bind the proximal fixation ring model to the proximal fracture model, and bind the distal fixation ring model to the distal fracture model to obtain the proximal combined model and the distal combined model, respectively;
[0048] Step 5: Adjust the positions of the proximal combined model and the distal combined model to achieve virtual repositioning between the proximal fracture model and the distal fracture model, and obtain the lengths of each extension rod of the Taylor space scaffold model in the repositioned state, i.e., the target length;
[0049] Step 6: Generate an electronic prescription based on the original and target lengths of each extension rod.
[0050] The above method can directly obtain the target length of each extension rod through virtual reset, and then calculate the target adjustment amount. This avoids the process of obtaining abnormal parameters through imaging or measurement methods, and calculating the target adjustment amount of the extension rod in combination with stent parameters. It also avoids the drawback of affecting the treatment effect due to the inaccuracy of a certain input parameter, and improves the reliability of electronic prescriptions.
[0051] Furthermore, since the parameters of the support frame are not required 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 skeleton is not at the center of the fixing ring or is not perpendicular to the plane of the fixing ring, the target adjustment amount of each extension rod can be accurately calculated.
[0052] In step 1, the image data is obtained from CT scan images using a CT scanning device. After acquiring the image data of the affected limb with the Taylor space scaffold, artifact processing is also performed. Specifically, filtering, such as median filters, Gaussian filters, and / or threshold segmentation, can be used to distinguish between metal signals and tissue signals, and metal signals exceeding the threshold are processed.
[0053] In step 2, the modeling can be done using digital medical modeling software or by directly segmenting and modeling on a CT scanner.
[0054] In steps 3 and 5, regarding the method for obtaining the length of the extension rod, as a specific implementation, in step 3, the connection points between each extension rod and the proximal and distal fixing ring models in the Taylor space support model are identified, and the original length of the extension rod is calculated based on the position of each connection point. In step 5, after performing a virtual reset, the target length of the extension rod is also calculated based on the position of each connection point. It is understood that the original and target lengths can be measured manually in the software or automatically calculated by a computer program based on the position of each connection point.
[0055] Using the above method, it is only necessary to obtain the connection points between each extension rod and the proximal and distal rings to accurately calculate the length of the extension rod, without needing to locate the position of each extension rod.
[0056] Because metal artifacts exist during imaging of the Taylor space scaffold, to avoid their influence on the model and ensure the accuracy of the extension rod length calculation, and also for ease of calculation, as an alternative implementation method, a standard model library is pre-established. This library includes standard models of Taylor space scaffolds from different manufacturers and models. In step 3, a standard model identical to the Taylor space scaffold is obtained. Using the proximal and distal fixation rings of the Taylor space scaffold as a reference, the standard model is registered to the Taylor space scaffold model, ensuring that the proximal and distal fixation rings of both coincide. The length of each connecting rod in the current state of the standard model is obtained, i.e., the original length. In step 4, the proximal fixation ring model of the registered standard model is bound to the proximal fracture model, and the distal fixation ring model is bound to the distal fracture model, resulting in the proximal combined model and the 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 is obtained, i.e., the target length.
[0057] Using the standard model as a bridge, the original lengths of each extension rod of the Taylor space external fixator before reduction are obtained by first matching it to the external fixator model in its original state before reduction; then, the standard model is bound to the fracture model, and virtual reduction is performed. In the virtual reduction state, the target lengths of each extension rod after reduction are obtained, which solves the problem of inaccurate calculation caused by metal artifacts.
[0058] Specifically, after obtaining the standard model, the connection points between each extension rod in the standard model and the proximal and distal fixing ring models are identified. Based on the connection point positions of each extension rod before and after the virtual reset, the original length and target length of the extension rod are calculated. Alternatively, a standard model parameter table can be pre-stored. This table includes identification information for each standard model (e.g., the corresponding support manufacturer and model) and the initial length of each extension rod in the standard model. In step 3, when the standard model is registered to the Taylor space support model, the matching transformation parameters of the standard model are obtained. Based on these matching transformation parameters and the initial lengths of each extension rod in the standard model, the length of each extension rod in its current state, i.e., the original length, is obtained. In step 4, when performing the virtual reset, the reset transformation parameters of the standard model are obtained. Based on these reset transformation parameters, the length of each extension rod after reset, i.e., the target length, is calculated.
[0059] In step 5, for general fractures, the position adjustment can be automatically achieved based on the cross-sections of the distal and proximal fractures. The fracture cross-sections of the distal and proximal fracture models are registered to achieve virtual reduction. Alternatively, it can be achieved manually by using 3D modeling software to manually drag, rotate, and perform other operations on the distal bone replica model to splice the cross-sections of the distal and proximal fracture models.
[0060] As another implementation method, image data of the patient's unaffected limb is acquired, and three-dimensional reconstruction is performed based on the image data to obtain a bone model of the unaffected side. Virtual repositioning is achieved by registering the proximal and distal combined models with the mirror image model of the unaffected limb. Those skilled in the art will understand that if the fracture surface of the proximal or distal bone is fragmented, it is difficult to perform virtual repositioning based on fracture surface splicing. In this case, the implementation method of acquiring image data of the unaffected limb is preferred.
[0061] For limb orthotics, a physician needs to determine the target position for adjustment to achieve virtual repositioning. Step 6, which generates an electronic prescription based on the original and target lengths of each extension rod, specifically includes:
[0062] (1) Calculate the target adjustment amount of each extension rod based on its original length and target length;
[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) Decompose 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 in multiple planes can be achieved.
[0067] In clinical applications, after installing the Taylor space support and issuing an electronic prescription, the user typically adjusts the extension rods daily according to the prescription. However, the target adjustment amounts for each extension rod can vary significantly. Some extension rods may have very small target adjustment amounts; for example, if a total adjustment of 3mm is required, this might be broken down over 100 days, requiring only 0.03mm adjustment per day. For the user, the smaller the adjustment amount, the more difficult it is to control the accuracy. Furthermore, there is a possibility of forgetting to adjust on a particular day, leading to an inability to strictly follow the prescription requirements. The longer the time, the greater the accumulated error. Therefore, in step (4), the required number of days is divided into stages to obtain a staged adjustment target, generating a staged electronic prescription. This staged electronic prescription includes the daily adjustment amount for each extension rod and the follow-up examination time within the corresponding time period of that stage. When the patient goes to the hospital for a follow-up examination according to the scheduled time, the doctor can determine whether the adjustment is being performed according to the prescription based on the length of each extension rod, facilitating timely intervention.
[0068] To avoid issues such as forgetting or inaccurate manual adjustments, the Taylor space support is electrically powered and 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, the electrically powered Taylor space support can adopt the form disclosed in patent document CN206381227U. After generating an electronic prescription, it is sent to the user terminal. Once the user terminal establishes a connection with the electrically powered Taylor space support, adjustments are made based on the daily adjustment amount in the electronic prescription.
[0069] Based on this, in order to reduce the patient's pain during daily adjustments, the electronic prescription also includes the number of daily adjustments (e.g., 3 times), the time of each adjustment, and the amount of each adjustment, so that the electric Taylor space support adjusts according to the set time, dividing the daily adjustment amount into multiple executions, which can significantly reduce the patient's pain and achieve imperceptible adjustment.
