Description

Technical Field

[0001] This invention relates to the field of medical technology, specifically to an open and compatible method and device for managing total hip joint prostheses. Background Technology

[0002] Before hip replacement surgery, it is necessary to select different manufacturers and types of hip prostheses based on the individual characteristics of different patients. There are many types of hip replacement prostheses, and many surgeons may only be familiar with one or a few of them. Therefore, the choice of prosthesis type in clinical application is largely influenced by the surgeon's clinical experience. After the prosthesis is determined, it is necessary to further estimate the prosthesis model and size. During preoperative planning, measurements are mainly taken based on X-rays and measurement templates provided by the manufacturer to estimate the prosthesis size, but it is impossible to accurately determine the prosthesis type and model. Often, poor postoperative results occur due to inappropriate selection of prosthesis type and model.

[0003] Patent CN116013477A provides a method and system for managing a prosthesis library for knee replacement surgery robots. It utilizes identifiers to record the matching relationships between femoral prostheses, tibial prostheses, and tibial plateau pads, using these as keys to create a corresponding database. By taking the model of any one or two prostheses selected by the user as input, a database lookup operation is performed to obtain the matching prosthesis model. However, this solution has the following drawbacks: when the number of prostheses is large and includes various types from different manufacturers, defining the matching relationships through identifiers requires maintaining a much larger number of matching relationships; if a prosthesis model is added or deleted, its related matching relationships also need to be processed accordingly, which is not conducive to data maintenance; and it relies too heavily on matching relationships, making it difficult to promptly handle errors in entered matching relationships, lacking data accuracy verification.

[0004] Patent CN105769393A provides a method and system for matching hip joint prostheses. This method aggregates data on different types of hip joint prostheses from various manufacturers, selects matching prostheses based on the patient's image information and individual characteristic parameters, and finally selects the best result based on the degree of matching. However, this approach has the following drawbacks: acquiring patient image information and individual characteristic parameters is complex, and selecting the prosthesis model based on these parameters is not accurate enough; if there are data errors when collecting patient image information or individual characteristic parameters, the selected prosthesis model will be incorrect, making it difficult to plan result verification and prosthesis data management.

[0005] Therefore, there is an urgent need for a prosthesis management method that can ensure the compatible assembly of prostheses from different manufacturers and the accuracy of the compatibility between different models. Summary of the Invention:

[0006] The purpose of this invention is to overcome the shortcomings of the existing technical solutions described in the background section and provide an open and compatible method and device for managing total hip joint prostheses. This invention enables compatibility with multiple brands of prostheses, which is beneficial for preoperative prosthesis planning and use. It also allows for direct visualization of the prosthesis fitting effect, significantly improving surgical efficiency.

[0007] This invention is achieved through the following technical solution: Firstly, this invention provides an open and compatible method for managing total hip arthroplasty prostheses, comprising the following steps: S101, Obtain prosthesis parameters; We obtained data on various specifications of prostheses required for hip replacement from our partner manufacturers, including models of the acetabular cup, liner, ball head, and femoral stem, as well as key parameters of the prosthesis modules. S102, 3D modeling and parameter measurement; Based on the prosthesis models and parameters provided by various manufacturers, a unified coordinate system model is constructed. According to the parameters required for preoperative prosthesis planning, measurements are taken on the prosthesis model and added to the existing prosthesis parameter list. The existing prosthesis parameters are then standardized. S103, Build the database; The database records data including: prosthesis parameter information and prosthesis model data; The implant parameter information includes the brand and model, the original implant parameters, and the necessary planning and measurement parameters; the implant model data is stored in binary format for easy parameter verification and preoperative planning. S104, Maintenance of prosthesis matching relationship; Based on the compatibility relationship between different prostheses, corresponding specification / model mapping functions and matching relationship functions are created, thereby recording the matching relationship between different prostheses into the prosthesis database in a two-level maintenance manner. The input parameter is the implant model, and the output is a list of matching implant information. The specification / model mapping function is used to standardize the input prosthesis model, so that prosthesis models from different brands have a unified naming convention. The matching function takes the normalized specifications / model and all prosthesis information as input parameters, performs prosthesis matching and comparison through specifications / model, and finally outputs the matching prosthesis information; S105, Prosthesis parameter verification; Based on the parameters of each prosthesis and the corresponding matching function, the prosthesis parameters are verified, and the prosthesis model and corresponding parameters are presented in a 3D view, along with the assembly effect.

[0008] Furthermore, the prosthesis matching described in S104 includes two usage methods: When matching implants from different brands, the input is the specific implant model, and the output is whether they are a match. When matching a single implant, the input is a single implant model, and the output is a list of matching implants, including implants from the same brand and implants from other brands.

[0009] Secondly, the present invention also provides an open and compatible total hip joint prosthesis management device, the device comprising: The data acquisition module is used to acquire prosthesis parameters; We obtained data on various specifications of prostheses required for hip replacement from our partner manufacturers, including models of the acetabular cup, liner, ball head, and femoral stem, as well as key parameters of the prosthesis modules. The modeling module is used for 3D modeling and parameter measurement; Based on the prosthesis models and parameters provided by various manufacturers, a unified coordinate system model is constructed. According to the parameters required for preoperative prosthesis planning, measurements are taken on the prosthesis model and added to the existing prosthesis parameter list. The existing prosthesis parameters are then standardized. The database module is used to build databases; The database records data including: prosthesis parameter information and prosthesis model data; The implant parameter information includes the brand and model, the original implant parameters, and the necessary planning and measurement parameters; the implant model data is stored in binary format for easy parameter verification and preoperative planning. The prosthesis matching module is used to maintain prosthesis matching relationships; Based on the compatibility relationship between different prostheses, corresponding specification / model mapping functions and matching relationship functions are created, thereby recording the matching relationship between different prostheses into the prosthesis database in a two-level maintenance manner. The input parameter is the implant model, and the output is a list of matching implant information. The specification / model mapping function is used to standardize the input prosthesis model, so that prosthesis models from different brands have a unified naming convention. The matching function takes the normalized specifications / model and all prosthesis information as input parameters, performs prosthesis matching and comparison through specifications / model, and finally outputs the matching prosthesis information; The verification module is used for verifying prosthesis parameters; Based on the parameters of each prosthesis and the corresponding matching function, the prosthesis parameters are verified, and the prosthesis model and corresponding parameters are presented in a 3D view, along with the assembly effect.

Detailed Implementation

[0013] The features and exemplary embodiments of various aspects of this disclosure will now be described in detail. To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description of this disclosure. It should be understood that the specific embodiments described herein are intended only to explain this disclosure and not to limit it. For those skilled in the art, this disclosure can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this disclosure by illustrating examples.

[0014] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0015] To better understand the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, this invention provides an open and compatible method for managing total hip arthroplasty prostheses, comprising the following steps: S101, Obtain prosthesis parameters; We obtained data on various specifications of prostheses required for hip replacement from our partner manufacturers, including models of the acetabular cup, liner, ball head, and femoral stem, as well as key parameters of the prosthesis modules.

[0017] S102, 3D modeling and parameter measurement; like Figure 2 As shown, a unified coordinate system model is constructed based on the prosthesis models and parameters provided by various manufacturers. Measurements are then taken on the prosthesis model according to the parameters required for preoperative prosthesis planning, and these measurements are added to the existing prosthesis parameter list. The existing prosthesis parameters are then standardized.

[0018] S103, Build the database; The database records data including: prosthesis parameter information and prosthesis model data. The prosthesis parameter information includes brand and model, original prosthesis parameters, and necessary planning and measurement parameters; the prosthesis model data is stored in binary format for easy parameter verification and preoperative planning.

[0019] The definition of the prosthesis model name is directly related to the subsequent prosthesis assembly. Therefore, when naming it, you need to refer to the prosthesis manual provided by the manufacturer and the naming format of other prostheses that are compatible with the prosthesis. This ensures the correspondence between the prosthesis model and the actual prosthesis and facilitates the differentiation during subsequent prosthesis fitting. The naming examples are shown in the table below. Since there is no correspondence between the femoral stem and the ball head, the naming can be based on the manufacturer's manual.

[0020] .

[0021] S104, Maintenance of prosthesis matching relationship; To ensure proper fitting of prostheses in various parts and compatibility between prostheses from different brands, this invention provides a prosthesis matching module, such as... Figure 3 As shown, this module includes: specification / model mapping function and matching relationship function. The input parameter is the implant model (which can be implants from different brands or implants from different parts of the body), and the output is a list of matching implant information.

[0022] The specification / model mapping function is used to standardize the input prosthesis model, so that prosthesis models from different brands have a unified naming convention. The matching relationship function takes the standardized specification / model and all prosthesis information as input parameters, performs prosthesis matching and comparison through specification / model, and finally outputs the matching prosthesis information.

[0023] Furthermore, prosthesis matching includes two usage methods: like Figure 4 As shown, when matching implants from different brands, the input is the specific implant model, and the output is whether they match. like Figure 5 As shown, when matching a single implant, the input is a single implant model, and the output is a list of matching implants, including implants from the same brand and implants from other brands.

[0024] S105, Prosthesis parameter verification; To ensure the correctness of prosthesis parameters and matching relationships, it is necessary to verify the currently entered prosthesis parameters and matching relationships. Therefore, a prosthesis parameter verification module is provided. This module verifies the prosthesis parameters based on each prosthesis parameter and the corresponding matching relationship function, and displays the prosthesis model and corresponding instantiated parameters (such as: marker points, bone cutting surfaces, etc.) by generating a 3D image. Figure 7 This is a display of prosthesis parameters and an assembly effect diagram.

[0025] like Figure 6 As shown, the prosthesis parameter verification can also be associated with the prosthesis matching module, which can display other prosthesis models and parameters that match the current prosthesis, making it easier for users to check the assembly effect and accuracy.

[0026] In addition, during preoperative planning, users can select the corresponding prosthesis model from the manufacturer and view the current 3D model and position of the prosthesis in real time. They can adjust the size and placement based on the display effect of the 3D skeleton and prosthesis model.

[0027] Secondly, the present invention also provides an open and compatible total hip joint prosthesis management device, the device comprising: The data acquisition module is used to acquire prosthesis parameters; We obtained data on various specifications of prostheses required for hip replacement from our partner manufacturers, including models of the acetabular cup, liner, ball head, and femoral stem, as well as key parameters of the prosthesis modules.

According to the parameters required for preoperative prosthesis planning, measurements are taken on the prosthesis model and added to the existing prosthesis parameter list. The existing prosthesis parameters are then standardized. The database module is used to build databases; The database records data including: prosthesis parameter information and prosthesis model data; The implant parameter information includes the brand and model, the original implant parameters, and the necessary planning and measurement parameters; the implant model data is stored in binary format for easy parameter verification and preoperative planning. The prosthesis matching module is used to maintain prosthesis matching relationships; Based on the compatibility relationship between different prostheses, corresponding specification / model mapping functions and matching relationship functions are created, thereby recording the matching relationship between different prostheses into the prosthesis database in a two-level maintenance manner. The input parameter is the implant model, and the output is a list of matching implant information. The specification / model mapping function is used to standardize the input prosthesis model, so that prosthesis models from different brands have a unified naming convention. The matching function takes the normalized specifications / model and all prosthesis information as input parameters, performs prosthesis matching and comparison through specifications / model, and finally outputs the matching prosthesis information; The verification module is used for verifying prosthesis parameters; Based on the parameters of each prosthesis and the corresponding matching function, the prosthesis parameters are verified, and the prosthesis model and corresponding parameters are presented in a 3D view, along with the assembly effect.
