Description

Technical Field

[0001] This application relates to the field of medical technology, and more specifically, to a data processing method and apparatus, storage medium and electronic device for prosthesis fixation nails. Background Technology

[0002] In the field of medical device technology, especially for joint replacement surgery, the existing technological framework faces significant challenges. In traditional hip replacement surgery, determining the placement and orientation of the acetabular cup fixation screw relies almost entirely on the surgeon's experience. Manually planning the screw placement is susceptible to individual experience and anatomical variations, leading to uncertainty in the screw's placement and orientation. In some cases, surgeons cannot accurately determine whether the screw will penetrate the thin bone wall.

[0003] There is currently no effective solution to the problem that related technologies rely on human experience to determine the implantation position and orientation of the fixation pins for the acetabular cup, resulting in low accuracy in determining the implantation position and orientation of the fixation pins. Summary of the Invention

[0004] The main objective of this application is to provide a data processing method and apparatus, storage medium and electronic device for prosthesis fixation screws, in order to solve the problem in the related art that the accuracy of determining the implantation position and direction of the fixation screws for the acetabular cup is relatively low due to reliance on human experience.

[0017] Furthermore, the judgment unit includes: a third determining module, used to determine a third distance value between the first fixation nail and the bone in the processed real three-dimensional model; an adjusting module, used to adjust the target implantation parameters if the third distance value is less than or equal to a threshold, and provide data reference for the implantation of the first fixation nail based on the adjusted target implantation parameters; and a reference module, used to provide data reference for the implantation of the first fixation nail based on the target implantation parameters if the third distance value is greater than the threshold.

[0018] Furthermore, the device further includes: a data acquisition unit, used to acquire first real implantation parameters of the first fixation screw and second real implantation parameters of the acetabular cup prosthesis when the acetabular cup prosthesis and the first fixation screw are implanted in the target object; a construction unit, used to construct a real three-dimensional model after implantation based on the first real implantation parameters and the second real implantation parameters; a calculation unit, used to calculate the deviation between the real three-dimensional model after implantation and the simulated three-dimensional model to obtain a deviation value; and an evaluation unit, used to perform a postoperative evaluation based on the real three-dimensional model after implantation and the deviation value to obtain an evaluation result.

[0019] According to another aspect of the present invention, an electronic device is also provided, comprising: a memory storing an executable program; and a processor for running the program, wherein the program executes the data processing method for the prosthesis fixation nail described above during runtime.

[0020] According to another aspect of the present invention, a computer-readable storage medium is also provided, the storage medium storing a program, wherein, when the program is running, the device where the storage medium is located executes the data processing method for the prosthesis fixation nail of any of the above-mentioned methods.

[0021] In this embodiment, the following steps are employed: Three-dimensional reconstruction is performed based on the medical imaging data of the target object and the acetabular cup prosthesis to obtain an initial three-dimensional model; based on the current pinhole of the acetabular cup prosthesis in the initial three-dimensional model, first implantation parameters of the first fixation pin are generated, wherein the first implantation parameters include at least the implantation direction and implantation length; based on the first implantation parameters, a simulated implantation operation is performed in the initial three-dimensional model to obtain a simulated three-dimensional model; a safety assessment is performed on the simulated three-dimensional model, and if the safety assessment result indicates that the safety assessment has passed, the target implantation parameters of the fixation pin of the acetabular cup prosthesis are determined based on the first implantation parameters. This solves the technical problem in related technologies where the determination of the implantation position and direction of the fixation pin of the acetabular cup relies on human experience, resulting in relatively low accuracy in determining the implantation position and direction of the fixation pin.

[0022] In this approach, medical imaging data of the patient's hip joint, such as CT or MRI scans, is collected and combined with information about the acetabular cup prosthesis to create an initial three-dimensional model of the patient's hip structure and the prosthesis to be implanted. Based on the current screw holes of the acetabular cup prosthesis in the initial three-dimensional model, the first implantation parameters of the first fixation screw are calculated and generated. Simulated implantation is performed within the initial three-dimensional model, i.e., through virtual surgery, visually presenting the state after screw implantation, resulting in a simulated three-dimensional model. A safety assessment is then conducted on the simulated three-dimensional model. If the safety assessment result indicates that the safety assessment is passed, the final target implantation parameters are obtained. By combining three-dimensional reconstruction, simulated implantation, and safety assessment, the limitations of surgical decisions based solely on planar images or manual intuition are avoided, eliminating uncertainties caused by human factors. This achieves precision, safety, and personalization of implantation parameters, thereby achieving the technical effect of accurately determining the implantation position and direction of the fixation screw.

[0040] Under the aforementioned operating environment, this application provides the following: Figure 2 The data processing method for the prosthesis fixation screws shown. Figure 2 This is a flowchart of a data processing method for a prosthesis fixation screw according to Embodiment 1 of this application. The data processing method for the prosthesis fixation screw includes:

[0041] Step S201: Based on the medical imaging data of the target object and the acetabular cup prosthesis, perform three-dimensional reconstruction to obtain an initial three-dimensional model.

[0042] Optionally, medical imaging data of the target object, i.e., the patient, can be acquired. This data can be CT (computed tomography) or MRI (magnetic resonance imaging) scans of the hip joint. Medical imaging data can provide detailed anatomical information, including bone shape, density, and any possible abnormalities.

[0043] After obtaining the medical imaging data, medical image processing software was used to preprocess the collected image data. Preprocessing included image enhancement, noise removal, and segmentation of bone and soft tissue to ensure the accuracy of the 3D reconstruction. Finally, based on the preprocessed medical imaging data and the acetabular cup prosthesis, a 3D reconstruction was performed to obtain an initial 3D model containing the patient's hip joint region and the acetabular cup prosthesis to be implanted. This model not only reproduced the anatomical features of the hip joint but also accurately simulated the implantation state of the acetabular cup prosthesis.

[0044] Step S202: Based on the current screw hole of the acetabular cup prosthesis in the initial three-dimensional model, generate the first implantation parameters of the first fixation screw, wherein the first implantation parameters include at least the implantation direction and the implantation length.

[0045] Optionally, the implantation direction and length of the first fixation screw are generated based on the current screw holes of the acetabular cup prosthesis in the initial 3D model. It should be noted that the acetabular cup prosthesis has multiple screw holes, and the implantation direction of the fixation screw can be determined based on these holes. For each screw hole, the implantation direction is vertical insertion with a preset vertical offset angle (e.g., 15 degrees). When determining the implantation direction and length, it is necessary to avoid penetrating the bone and to avoid damaging surrounding blood vessels, nerves, and other soft tissues.

[0046] Step S203: Based on the first implantation parameters, perform a simulated implantation operation in the initial three-dimensional model to obtain a simulated three-dimensional model.

[0047] Optionally, the first implantation parameters calculated in step S202, namely the screw implantation direction and length, are input into the surgical planning software to ensure that these parameters accurately correspond to the positions of the acetabular cup prosthesis and screw holes in the initial three-dimensional model. Based on the first implantation parameters, a virtual screw is generated at a specified location in the three-dimensional model, visually representing its expected trajectory and position in the bone in the form of a screw model. The software's simulation function can be used to implant the virtual screw into the simulated screw hole of the acetabular cup prosthesis along the preset implantation direction and length, while dynamically displaying the screw's path in the bone, reflecting the state of the acetabular cup prosthesis after screw implantation and the changes in the surrounding bone structure, forming a simulated three-dimensional model containing all implantation information.

[0048] Step S204: Perform a safety assessment on the simulated three-dimensional model, and if the safety assessment result indicates that the safety assessment has passed, determine the target implantation parameters of the fixation screw of the acetabular cup prosthesis based on the first implantation parameters.

[0049] Optionally, a safety assessment may be performed on the simulated 3D model, including but not limited to: comparing the screw implantation depth with the safe thickness of the bone wall to ensure that the screw does not penetrate the bone wall and avoid damage to blood vessels and nerves; checking the distance between the screw implantation path and important anatomical structures (such as blood vessels, nerves, muscles, etc.) to ensure a safe distance to avoid complications; and assessing the stability of the acetabular cup prosthesis after screw implantation, taking into account the patient's specific bone condition and anatomical structure, to ensure that the implanted prosthesis can provide long-term stable support.

[0050] It should be noted that the safety assessment results can be displayed intuitively on the software interface. If the assessment result indicates safety, i.e., the safety assessment is passed, the target implantation parameters are determined based on the first implantation parameters. If safety issues exist, specific risk points will be indicated, and parameter adjustment schemes can be recommended, such as changing the implantation direction, shortening the implantation length, or reselecting the screw hole position to mitigate risks.

[0051] Automated safety assessments enable the development of safe and personalized screw implantation protocols based on each patient's unique anatomy and biomechanical conditions.

[0052] Optionally, in the data processing method for the prosthesis fixation nail provided in the embodiments of this application, the safety assessment of the simulated three-dimensional model includes: determining a first distance value between the first fixation nail and the bone in the simulated three-dimensional model; if the first distance value is greater than a preset threshold, calculating the mechanical stability of the acetabular cup prosthesis in the simulated three-dimensional model to obtain the calculation result; and obtaining the safety assessment result based on the calculation result.

[0053] In an optional embodiment, safety assessment based on a simulated 3D model includes: determining a first distance value between the distal end of the first fixation screw and the bone through precise calculation within the simulated 3D model. This distance value is directly related to the safety of screw implantation, ensuring that the screw does not penetrate the bone wall and cause damage to surrounding nerves, blood vessels, or soft tissues. The first distance value is compared to a preset safety threshold. The preset threshold can be a value set based on clinical experience and safety standards (e.g., 1 mm), representing the minimum safe distance that should be maintained between the screw and the bone. If the first distance value is greater than the preset threshold, it indicates that the screw implantation procedure is safe in terms of penetration risk, and its mechanical stability can be further evaluated.

[0054] Once the safe distance of the first fixation screw is verified, the mechanical stability of the acetabular cup prosthesis after screw implantation will be further calculated. This includes indicators such as the contact area between the screw and bone, the screw fixation torque, and the overall stability index of the prosthesis, to assess the stability of the implantation plan. If the screw implantation poses no risk of penetration and ensures stable fixation of the acetabular cup prosthesis, the safety assessment result will be deemed satisfactory. Otherwise, the screw implantation parameters, such as orientation and length, need to be adjusted until all safety and stability criteria are met.

[0055] By calculating the first distance value, it is ensured that screw implantation will not cause excessive pressure or damage to the bone and surrounding tissues, thus achieving refined management and control of safety risks. The mechanical stability calculation can evaluate the support effect of screw implantation on the acetabular cup prosthesis, ensuring that the screw can provide sufficient fixation force without causing bone damage or other biomechanical problems due to over-tightening, thereby optimizing the biomechanical performance of the surgery and improving the long-term stability and durability of the prosthesis.

[0056] Optionally, in the data processing method for prosthesis fixation nails provided in the embodiments of this application, the method further includes: if the first distance value is less than or equal to a preset threshold, adjusting the first implantation parameter to obtain the second implantation parameter; if the second distance value corresponding to the second implantation parameter is less than or equal to the preset threshold, regenerating the implantation parameter of the first fixation nail based on the next nail hole of the acetabular cup prosthesis in the initial three-dimensional model, so as to ensure that the distance value corresponding to the current implantation parameter of the first fixation nail is greater than the preset threshold.

[0057] In an optional embodiment, if the first distance value does not meet the safety standard, the first implantation parameters are adjusted to generate second implantation parameters. Adjustment methods include, but are not limited to, changing the screw implantation angle, shortening the screw length, or replanning another screw hole on the same acetabular cup prosthesis.

[0058] Then, based on the second implantation parameters, a new distance value between the screw and the bone is calculated, i.e., the second distance value. If the adjusted second distance value is still less than or equal to a preset threshold, it indicates that there is still a safety risk in the current screw hole location or screw parameters. If the shortest screw still cannot avoid penetration, the screw hole is automatically marked as high-risk, and the process jumps to the next screw hole location in the initial 3D model, regenerates the implantation parameters of the first fixation screw, and begins a new round of evaluation loops until a screw implantation scheme that meets the safety standards is found.

[0059] By adjusting parameters individually based on each patient's specific bone condition and anatomical structure, the most suitable screw implantation plan can be found for each patient, improving the accuracy of determining implantation parameters.

[0060] Optionally, in the data processing method for the fixation screw of the prosthesis provided in the embodiments of this application, the method further includes: if the safety assessment result indicates that the safety assessment is not passed, then generating a third implantation parameter for the second fixation screw based on the next screw hole of the acetabular cup prosthesis in the initial three-dimensional model; performing simulated implantation in the initial three-dimensional model based on the first implantation parameter and the third implantation parameter to obtain an updated simulated three-dimensional model; performing a safety assessment based on the updated simulated three-dimensional model, and if the safety assessment result indicates that the safety assessment is passed, determining the target implantation parameter for the fixation screw of the acetabular cup prosthesis based on the first implantation parameter and the third implantation parameter.

[0061] In an optional embodiment, if stability issues arise when the first implantation parameters (including orientation and length) of the first fixation screw are assessed for safety in the initial simulated 3D model, then a third implantation parameter for the second fixation screw is generated based on the next screw hole position of the acetabular cup prosthesis in the initial 3D model. The first implantation parameters of the first fixation screw are combined with the third implantation parameters of the second fixation screw to simulate composite implantation in the initial 3D model, generating an updated simulated 3D model that includes the implantation states of both screws.

[0062] The updated simulated 3D model undergoes a safety assessment, including determining whether the safe distance between the screws and bone meets a preset threshold, and evaluating the mechanical stability of the acetabular cup prosthesis. Once the safety assessment is deemed successful—meaning all screw implantation is safe and the acetabular cup prosthesis stability meets the standards—the target implantation parameters for the fixation screws of the acetabular cup prosthesis are determined based on the first and third implantation parameters. These parameters will guide the actual surgical procedure, ensuring the long-term stability of the acetabular cup prosthesis.

[0063] By fully assessing and adjusting screw implantation parameters during the preoperative planning phase, the long-term stability of the acetabular cup prosthesis can be ensured.

[0064] Optionally, in the data processing method for the fixation screw of the prosthesis provided in the embodiments of this application, after determining the target implantation parameters of the fixation screw of the acetabular cup prosthesis, the method further includes: obtaining a real three-dimensional model when the acetabular cup prosthesis is implanted in the target object; processing the first implantation parameters through the screw guide to determine the screw three-dimensional model of the first fixation screw; adding the screw three-dimensional model to the real three-dimensional model to obtain the processed real three-dimensional model; and determining whether to adjust the target implantation parameters based on the processed real three-dimensional model.

[0065] In an optional embodiment, after the acetabular cup prosthesis is successfully implanted in the target object, an intraoperative imaging technique such as CT, MRI or advanced ultrasound is used to obtain a true three-dimensional model of the patient's hip region. It should be noted that the true three-dimensional model includes detailed information such as the actual position of the acetabular cup prosthesis after surgery and the immediate state of the patient's bone.

[0066] Using a screw guide, a positioning tool used to guide screw implantation, the first implantation parameters (including screw orientation and length) are acquired and processed to generate a virtual 3D model that accurately reflects the screw's position and shape (i.e., the aforementioned screw 3D model). This generated screw 3D model is then added to the real 3D model to obtain the processed real 3D model, which is a complete model containing the actual state of the implanted acetabular cup prosthesis and screw. This integration process provides intuitive visual feedback, allowing clear observation of the screw's actual position and effect within the patient's body.

[0067] Based on the processed realistic 3D model, the actual effect of screw implantation is evaluated, including the safe distance between the screw and the bone, and the stability of screw implantation. If the evaluation results indicate that the target implantation parameters need to be adjusted, the parameters are adjusted to ensure the safety of screw implantation and the stability of the acetabular cup prosthesis.

[0068] For example, the spatial position and orientation of the screw implantation guide are tracked by an optical navigation system, and a virtual screw model (generated according to the preoperative planned length) is dynamically displayed at the end of the guide in the software interface. The bone thickness along the proposed screw implantation path is calculated. If a potential penetration risk is detected, the penetration area is marked in the 3D model and the penetration distance is quantified (e.g., "Expected penetration: 2.3mm"). Combined with a preset safety threshold (e.g., retain 1mm of bone), the 3D relationship between the screw and the patient's bone is overlaid and displayed, with color coding (e.g., green for safety / red for danger) providing intuitive feedback on the safety of the current drilling path. Based on the safety assessment results, the system intelligently recommends adjustment schemes: length adjustment: automatically shortening the screw to the maximum safe length (e.g., from 30mm → 25mm); path optimization: providing optional adjacent screw holes or fine-tuning angle suggestions (within ±5°); after confirming the adjustment, the software immediately updates the virtual screw model, forming a closed-loop feedback.

[0069] Evaluations based on real 3D models can more accurately identify potential safety risks, such as screw penetration into bone or impact on nerves and blood vessels, thus improving the safety of screw implantation and the stability of the acetabular cup prosthesis.

[0070] Optionally, in the data processing method for prosthesis fixation nails provided in the embodiments of this application, determining whether to adjust the target implantation parameters based on the processed real three-dimensional model includes: determining a third distance value between the first fixation nail and the bone in the processed real three-dimensional model; if the third distance value is less than or equal to a threshold, adjusting the target implantation parameters and providing data reference for the implantation of the first fixation nail based on the adjusted target implantation parameters; if the third distance value is greater than the threshold, providing data reference for the implantation of the first fixation nail based on the target implantation parameters.

[0071] In an optional embodiment, a precise third distance value between the first fixation screw and the bone is calculated in the processed realistic 3D model. This distance value is an important indicator for assessing the safety of screw implantation, reflecting the actual safe distance between the screw and the patient's bone. The third distance value is compared with a preset threshold. If the third distance value is less than or equal to the threshold, it indicates a safety risk in screw implantation, potentially touching or penetrating the bone, requiring adjustment of the target implantation parameters (including the screw's orientation and length). The adjustment process includes, but is not limited to, fine-tuning the screw orientation, shortening the screw length, or changing the implantation point location.

[0072] After parameter adjustment, precise data reference is provided for the implantation of the first fixation nail based on the adjusted target implantation parameters. If the third distance value is greater than the threshold, it indicates that the current implantation scheme is safe enough, and data reference is provided directly for the implantation of the first fixation nail based on the target implantation parameters without additional adjustment.

[0073] By calculating the third distance between the first fixation screw and the bone, potential screw implantation risks can be quickly identified, ensuring the accuracy and effectiveness of the adjustment plan, avoiding subjective judgments based on predictions or experience, and achieving data-driven decision optimization.

[0074] Optionally, in the data processing method for the prosthesis fixation screw provided in the embodiments of this application, the method further includes: when the acetabular cup prosthesis and the first fixation screw are implanted in the target object, collecting the first real implantation parameters of the first fixation screw and the second real implantation parameters of the acetabular cup prosthesis; constructing a real three-dimensional model after implantation based on the first real implantation parameters and the second real implantation parameters; calculating the deviation between the real three-dimensional model after implantation and the simulated three-dimensional model to obtain the deviation value; and performing postoperative evaluation based on the real three-dimensional model after implantation and the deviation value to obtain the evaluation result.

[0075] In an optional embodiment, postoperatively, the actual implantation parameters of the first fixation screw are acquired, including its actual position, angle, and depth, as well as the second actual implantation parameters of the acetabular cup prosthesis, such as its actual position, orientation, and stability. Using the acquired first and second actual implantation parameters, a realistic three-dimensional model of the implanted device is constructed. This model includes the bone structure of the patient's hip region, the implantation status of the acetabular cup prosthesis, and the actual implantation position of the screw.

[0076] The actual 3D model after implantation is compared with the preoperative planned simulated 3D model, and the deviation values ​​between the two are calculated, including deviations in screw implantation position, angle, and depth. The deviation calculation is based on coordinate system matching and precise measurement of 3D spatial distances, providing quantitative indicators for postoperative evaluation. Based on the actual 3D model after implantation and the calculated deviation values, postoperative evaluation can be performed, yielding evaluation results. Evaluation results include, but are not limited to, the safety of screw implantation, the stability of the acetabular cup prosthesis, the overall biomechanical effect, and whether further correction or treatment is needed.

[0077] By collecting and analyzing implantation parameters, the accuracy of prosthesis implantation can be accurately assessed and deviations identified, which helps to make more precise operation plans in the future and improves the accuracy of subsequent screw implantation parameters.

[0078] In an alternative embodiment, the following can be employed: Figure 3 The diagram illustrates the method for determining the fixation screws for the acetabular prosthesis, specifically including: Preoperative planning and prosthesis position planning: Based on 3D reconstruction using the patient's CT data, the optimal implantation position and angle of the acetabular prosthesis are determined. Intelligent screw planning: Target screw holes are selected on the prosthesis model, and the system automatically generates recommended screw directions and lengths, simulating the implantation effect in real time. The relative position of the screw and bone is displayed through a visual interface, intelligently assessing the risk of penetration. If a risk exists, the system prompts adjustments to the screw length or direction. Dynamic optimization and adjustment: If even the shortest screw cannot prevent penetration, the system automatically marks the screw hole as high-risk and recommends the following solutions: replace with other screw holes; fine-tune the prosthesis position or angle, and reassess screw safety. Comprehensive stability assessment: The system calculates the mechanical stability of the prosthesis in real time. If the current screw configuration does not meet stability requirements, the system continues to optimize the screw hole selection and screw parameters until both the prosthesis position and screw configuration meet the dual standards of safety and stability.

[0079] Tool Calibration: A positioning tool with a marker ball is fixed to the instrument to be calibrated (implantation punch guide, verification pin tool, prosthesis implantation tool). The spatial pose of the tool is captured optically, establishing a coordinate mapping relationship between the instrument and the navigation system. Pruning Punch Guide Calibration: The guide tip is aligned with the calibration target. The system automatically calculates the offset between its geometric center and the optical marker; the matching degree between the guide axis and the virtual planned path is verified. Recalibration is triggered when the error exceeds a threshold (e.g., 0.5mm). Verification Pin Tool Calibration: The length and diameter parameters of the tool are calibrated by contacting known coordinate points with a physical probe, ensuring postoperative verification accuracy. Prosthesis Implantation Tool Calibration: The mechanical interface between the tool's clamping end and the prosthesis is matched, and the implantation angle and depth compensation parameters are calibrated. Calibration Data Storage: Calibration parameters are encrypted and stored in the navigation system, supporting real-time intraoperative retrieval and abnormal status alerts.

[0080] Acetate preparation: Register and grind the acetabulum according to the hip replacement surgery navigation or robotic system surgical procedure; Prosthesis implantation: Implant the prosthesis and drill holes for screw implantation according to the hip replacement surgery navigation or robotic system surgical procedure.

[0081] The optical navigation system tracks the spatial position and orientation of the drilling guide in real time, dynamically displaying a virtual screw model (generated according to the preoperative planned length) at the end of the guide in the software interface. The three-dimensional relationship between the screw and the patient's bone is overlaid, and color coding (e.g., green for safety / red for danger) provides intuitive feedback on the safety of the current drilling path. Intelligent safety assessment: Based on real-time bone recognition algorithms from intraoperative CT or ultrasound, the bone thickness along the planned screw implantation path is calculated. If a potential penetration risk is detected, the penetration area is automatically marked and the penetration distance is quantified (e.g., "Expected penetration: 2.3mm"). Combined with a preset safety threshold (e.g., retaining 1mm of bone), a real-time warning is triggered. Dynamic parameter optimization: Based on the safety assessment results, intelligent adjustment plans are recommended: Length adjustment: Automatically shortens the screw to the maximum safe length (e.g., from 30mm → 25mm); Path optimization: Provides optional adjacent screw holes or fine-tuning angle suggestions (within ±5°). After confirmation of the adjustment, the software immediately updates the virtual screw model, forming a closed-loop feedback.

[0082] Prosthesis verification uses a probe to verify the implantation position; screw verification involves precise positioning verification: a specialized verification tool with optical markers is used to measure the actual position of the implanted screws with high precision (accuracy up to ±0.2mm); the deviation vector (including angular offset and displacement distance) between the 3D model of the actual screw position and the preoperative planned position is displayed in real time on the navigation system interface. Postoperative results show the actual implantation position and actual implantation length of the screws, determining whether the prosthesis is stable and safe postoperatively.

[0083] In an alternative embodiment, the following can be employed: Figure 4 The diagram illustrates the method for determining the fixation screw for the acetabular cup, specifically including: Preoperative planning and 3D reconstruction from CT data: Receiving CT scan data of the patient's hip and generating a 3D model of the hip bone. Prosthesis position / angle planning: Based on the 3D model, planning the optimal implantation position and angle of the acetabular cup prosthesis. Selecting target screw holes: After determining the prosthesis position and angle, selecting predetermined screw holes on the prosthesis model as the target locations for screw implantation. When selecting screw holes, factors such as bone thickness, screw fixation effectiveness, and prosthesis stability need to be considered. Generating screw direction / length suggestions: Once a screw hole is selected, a recommended screw direction and length will be automatically generated based on the current implantation position and angle. Visualized simulation of implantation: The screw implantation process is simulated in real time through a 3D interface, intuitively displaying the relative position and contact state between the screw and the bone, and showing the effect after screw implantation, including whether it penetrates the bone and its relationship with surrounding structures.

[0084] Bone Penetration Detection: The system determines whether the screw might penetrate the bone. If the result is yes, the system will indicate a high risk and parameter adjustments are needed. If the result is no, the screw implantation is relatively safe, and the next evaluation step can proceed. Screw Parameter Adjustment: When the system determines that screw implantation carries a risk of bone penetration, the surgeon can adjust the screw length, direction, or choose a different screw hole to mitigate the risk. The system will update the simulation results in real time to ensure the adjusted plan is safe and feasible. Prosthesis Stability Assessment: After adjusting the screw direction and length, the system will assess whether the stability of the acetabular cup prosthesis meets the pre-set surgical standards. If stability is met, the final plan can be saved; if not, the screw hole needs to be changed or the prosthesis position and angle need to be fine-tuned again. Screw Hole Change / Prosthesis Fine-tuning: When screw adjustments cannot meet the prosthesis stability requirements, a different screw hole position is used, or the prosthesis position and angle are fine-tuned, and the screw direction and length are replanned. Saving the Final Plan: When the screw implantation direction and length, as well as the prosthesis position and angle, are determined to be safe and stable, the final preoperative planning plan is obtained. The saved protocol will be used to guide the implementation of the surgery, ensuring the safety and accuracy of the procedure.

[0085] In one optional embodiment, a set of embodiments of the present invention is as follows: Preoperative planning: First, the prosthesis position is planned. Based on the prosthesis placement, screw holes are selected on the prosthesis for screw placement, and the software displays the screw positions. The first screw is planned; based on the screw position displayed in the software, a 30mm screw is determined to penetrate the bone, and the screw length is adjusted to 20mm. The second screw is planned; the shortest screw will still penetrate the bone, so this screw hole is abandoned, and the screw hole is replaced with a 5mm screw with the first screw rotated. At this point, the prosthesis is unstable, so a third screw is placed, and the screw length is adjusted to 30mm, ensuring proper prosthesis placement and screw placement. Tool calibration: The screw guide and verification screw tool are calibrated according to the optical positioning device and positioning tools, and the prosthesis implantation tool is calibrated. Acetabular preparation: The acetabulum is registered and ground according to the hip replacement surgery navigation or robotic system surgical procedure. Prosthesis implantation: The hip replacement surgery is performed according to the procedure... The surgical procedure, guided by a navigation or robotic system, involves implanting the prosthesis; drilling and screw placement, with the implantation guide displayed and tracked. The first screw is shown at the end of the guide, and the software indicates it has not penetrated the bone, confirming its safe position. Drilling and implanting the screw proceeds. Switching to the second screw, the software again indicates it has not penetrated the bone, confirming its safe position. Drilling and implanting the second screw proceeds. Switching to the third screw, the software indicates it has penetrated 5mm of bone, and the length is set to 25mm. The third screw is confirmed to be safe in its current position, and drilling and implanting the third screw proceeds. Prosthesis verification is performed using a probe to verify the implantation position. Screw verification is also performed using a screw verification tool to verify that all three screws are safely in place. Postoperative results show the actual implantation position and length of the screws, indicating postoperative prosthesis stability and safety.

[0086] The data processing method for the fixation screw of the acetabular cup provided in this application embodiment obtains an initial three-dimensional model by performing three-dimensional reconstruction based on the medical imaging data of the target object and the acetabular cup prosthesis; generates first implantation parameters for the first fixation screw based on the current screw hole of the acetabular cup prosthesis in the initial three-dimensional model, wherein the first implantation parameters include at least the implantation direction and the implantation length; performs a simulated implantation operation in the initial three-dimensional model based on the first implantation parameters to obtain a simulated three-dimensional model; performs a safety assessment on the simulated three-dimensional model, and determines the target implantation parameters of the fixation screw of the acetabular cup prosthesis based on the first implantation parameters if the safety assessment result indicates that the safety assessment is passed. This solves the technical problem in related technologies that rely on human experience to determine the implantation position and direction of the fixation screw of the acetabular cup, resulting in relatively low accuracy in determining the implantation position and direction of the fixation screw.

[0087] In this approach, medical imaging data of the patient's hip joint, such as CT or MRI scans, is collected and combined with information about the acetabular cup prosthesis to create an initial three-dimensional model of the patient's hip structure and the prosthesis to be implanted. Based on the current screw holes of the acetabular cup prosthesis in the initial three-dimensional model, the first implantation parameters of the first fixation screw are calculated and generated. Simulated implantation is performed within the initial three-dimensional model, i.e., through virtual surgery, visually presenting the state after screw implantation, resulting in a simulated three-dimensional model. A safety assessment is then conducted on the simulated three-dimensional model. If the safety assessment result indicates that the safety assessment is passed, the final target implantation parameters are obtained. By combining three-dimensional reconstruction, simulated implantation, and safety assessment, the limitations of surgical decisions based solely on planar images or manual intuition are avoided, eliminating uncertainties caused by human factors. This achieves precision, safety, and personalization of implantation parameters, thereby achieving the technical effect of accurately determining the implantation position and direction of the fixation screw.
