Technical Field

[0001] This invention belongs to the field of medical device management technology, specifically relating to a method and system for calculating the lifespan of root canal files used in root canal treatment equipment. Background Technology

[0002] If a root canal file breaks during use, it can potentially cause injury to the patient or dentist. Therefore, assessing the fatigue condition of root canal files and calculating their remaining lifespan to ensure timely replacement is crucial for root canal treatment. Currently, the remaining lifespan of root canal files is primarily assessed based on their usage time.

[0003] However, in practice, it has been found that the intensity of use of root canal files during actual root canal treatment is dynamic. Different intensities of use within the same time period will cause different instrument fatigue to the root canal files. Therefore, the method of assessing the remaining lifespan of root canal files based on the usage time of the files is prone to misjudgment, and the accuracy of the assessment of the remaining lifespan of root canal files is low.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, or product may include a series of steps or units, or may not be limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or processes.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] If a root canal file breaks during use, it can potentially cause injury to the patient or dentist. Therefore, assessing the fatigue condition of root canal files and calculating their remaining lifespan to ensure timely replacement is crucial for root canal treatment. Currently, the remaining lifespan of root canal files is primarily assessed based on their usage time.

[0029] However, in practice, it has been found that the intensity of use of root canal files during actual root canal treatment is dynamic. Different intensities of use within the same time period will cause different instrument fatigue to the root canal files. Therefore, the method of assessing the remaining lifespan of root canal files based on the usage time of the files is prone to misjudgment, and the accuracy of the assessment of the remaining lifespan of root canal files is low.

[0030] Therefore, improving the accuracy of assessing the remaining lifespan of root canal files is a pressing technical problem that needs to be solved.

[0031] To address the aforementioned technical problems, this invention discloses a method and system for calculating the remaining lifespan of root canal files used in root canal treatment equipment, aiming to improve the accuracy of assessing the remaining lifespan of root canal files. These are described in detail below.

[0032] Example 1 Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for calculating the lifespan of a root canal file used in root canal treatment equipment, as disclosed in an embodiment of the present invention. Figure 1 The method shown can be applied to root canal file life calculation systems, which can improve the accuracy of assessing the remaining lifespan of root canal files. Furthermore, this system can be integrated into the control system of root canal treatment equipment. Root canal treatment equipment includes mechanical reamers, such as… Figure 1 As shown, the method for calculating the lifespan of a root canal file used in root canal treatment equipment disclosed in this embodiment of the invention includes, but is not limited to, the following operations: 101. Obtain the real-time torque data collected by the reamer motor during the current root canal treatment; the real-time torque data is the rotational torque data of the target root canal file connected to the reamer motor; 102. Based on the real-time torque data, calculate the cumulative damage to obtain the current cumulative damage data of the target root canal file during the current root canal treatment process; 103. Calculate the remaining life of the target root canal file based on the current cumulative damage data to obtain the target remaining life.

[0033] It should be noted that the root canal treatment device in this embodiment of the invention also includes an intelligent management terminal. The intelligent management terminal communicates with the mechanical reamer motor via wired or wireless means. The intelligent management terminal can receive data collected by the mechanical reamer motor and process the data to calculate the remaining lifespan of the root canal file.

[0034] In this embodiment of the invention, real-time torque data collected by the reamer motor during the current root canal treatment is acquired; then, damage accumulation calculation is performed based on the real-time torque data to obtain the current cumulative damage data of the target root canal file during the current root canal treatment; finally, the remaining lifespan of the target root canal file is calculated based on the current cumulative damage data to obtain the target remaining lifespan. By acquiring the real-time torque of the root canal file to quantify the usage intensity of the root canal file, and calculating the instrument damage of the root canal file based on the real-time torque, the remaining lifespan of the root canal file can be assessed. Compared with simply accumulating "usage time" to assess the lifespan of the root canal file, the assessment of the remaining lifespan of the root canal file has higher accuracy and reliability.

[0035] In an optional embodiment, cumulative damage calculation is performed based on real-time torque data to obtain the current cumulative damage data of the target root canal file during the current root canal treatment process, including: The real-time torque data is divided into time series to obtain a set of time segments. The set of time segments includes multiple target time segments. Each target time segment has a corresponding target torque value. The target torque value is used to characterize the rotational torque of the target root canal file in the target time segment corresponding to the target torque value. For each target time segment in the time segment set, the instrument damage of the target root canal file in the target time segment is calculated based on the target torque value corresponding to the target time segment, and the segment damage value corresponding to the target time segment is obtained. The damage values ​​of all target time segments are summed to obtain the current cumulative damage data of the target root canal file during the current root canal treatment process.

[0036] It should be noted that for a specific type of root canal file, the time it can withstand a constant torque before fatigue fracture is limited, and this "limited duration" has a highly non-linear negative correlation with the torque value. Within the same time frame, the instrument damage suffered by a root canal file under high torque conditions is significantly greater than that under low torque conditions.

[0037] Through extensive destructive testing, the average limiting time L_i of a certain type of root canal file under different constant torques T_i can be obtained. For example, some experimental data for a certain type of root canal file are as follows: At a torque of 0.3 N·cm, the average limit duration is 360 seconds; At a torque of 0.6 N·cm, the average limit duration is 200 seconds; At a torque of 1.0 N·cm, the average limit duration is 150 seconds; ... After obtaining the experimental data, the torque T is plotted on the x-axis and the extreme duration L is plotted on the y-axis. The data points (T_i, L_i) are then fitted with a curve to obtain the "torque-extreme duration" characteristic curve of this type of file. Its mathematical expression can be written as: L=F(T), where F(T) is a nonlinear decay function determined by the experimental data. It can usually be expressed as a power function or an exponential function, such as L=A*T^(-B), where A and B are material constants determined by fitting.

[0038] In this optional embodiment, the damage effect of varying torque is mapped onto the aforementioned characteristic curve for calculation. The real-time torque data is divided, with the torque of the root canal file considered constant within extremely short time segments, thereby calculating the damage suffered by the root canal file during this period. The damage suffered by the root canal file in all time segments is then summed to obtain the total damage suffered by the root canal file during this treatment.

[0039] The method for calculating the remaining lifespan of root canal files in this invention reflects the nonlinear core principle that "damage caused by high torque is much faster than that caused by low torque," realizing a shift from "timekeeping" to "damage measurement." Compared with simply accumulating "usage time" to evaluate the lifespan of root canal files, the accuracy and reliability of evaluating the remaining lifespan of root canal files are significantly improved.

[0040] In another optional embodiment, for each target time segment in the time segment set, the instrument damage of the target root canal file within the target time segment is calculated based on the target torque value corresponding to the target time segment, to obtain the segment damage value corresponding to the target time segment, including: For each target time segment in the time segment set, the target torque value corresponding to the target time segment is matched with the target torque value according to the pre-stored torque-duration database to obtain the target limit duration corresponding to the target torque value. The ratio of the duration of the target time segment to the target limit duration is calculated to obtain the segment damage value corresponding to the target time segment. The target limit duration is the average limit working time of other root canal files of the same model as the target root canal file at the target torque value.

[0041] In this optional embodiment, the torque-duration database stores data on the maximum operating time of different types of root canal files under multiple constant torques. For the nth target time segment, the average maximum operating time of the target root canal file at the target torque value T_n can be obtained by querying the torque-duration database as L_current=F(T_n). The segment corresponding to this target time segment is D_n=Δt_n / L_current, where Δt_n represents the duration of the nth target time segment.

[0042] In yet another optional embodiment, the remaining life of the target root canal file is calculated based on the current cumulative damage data to obtain the target remaining life, including: Retrieve pre-stored historical cumulative damage data; historical cumulative damage data is the cumulative damage data of the target root canal file during historical root canal treatments; Calculate the sum of the current cumulative damage data and the historical cumulative damage data to obtain the target cumulative damage value; Calculate the difference between the target cumulative damage value and the target cumulative damage value, and convert it to a percentage to obtain the target remaining lifespan.

[0043] In this optional embodiment, the target cumulative damage value is: D_total = D_past + Σ(Δt_i / F(T_i)), where T_i is the target torque value corresponding to the i-th target time segment, and D_past is the historical cumulative damage data. It is understood that if the target root canal file has not been used before, the historical cumulative damage data is zero.

[0044] In another optional embodiment, to further improve the comprehensiveness and clinical applicability of the assessment of the remaining lifespan of root canal files, the embodiments of the present invention may also include the synchronous acquisition and fusion analysis of rotational speed data during the use of root canal files. Specifically, the mechanical reamer motor of the root canal treatment device can not only acquire real-time torque data of the target root canal file, but also synchronously acquire its real-time rotational speed data. Before calculating the cumulative damage based on the real-time torque data, the following operations are also included: Acquire real-time rotation speed data collected by the reamer motor during the current root canal treatment process; the real-time rotation speed data is the rotational speed data of the target root canal file connected to the reamer motor at the corresponding time point; Based on real-time torque and speed data, cumulative composite stress damage is calculated to obtain the current cumulative composite damage data of the target root canal file during the current root canal treatment process.

[0045] In this alternative implementation, the fatigue damage experienced by root canal files during actual operation is not determined solely by torque. Variations in rotational speed affect the stress cycle frequency, frictional heating effect, and fretting wear mechanisms within the material. Higher rotational speeds may lead to faster fatigue accumulation at the same torque, especially when the file encounters local resistance within the root canal or experiences slight bending; the coupling effect of centrifugal force and alternating stress exacerbates the damage process. Therefore, introducing a rotational speed parameter allows for a more precise characterization of the dynamic working state of the root canal file.

[0046] In another optional embodiment, after calculating the remaining life of the target root canal file based on the current cumulative damage data, the root canal file life calculation method for root canal treatment equipment disclosed in this embodiment of the invention further includes: The remaining lifespan of the target is compared with a preset lifespan threshold to obtain the lifespan comparison result; If the target remaining lifespan is less than the preset lifespan threshold, an alarm will be issued to the healthcare personnel using the root canal treatment equipment indicating that the root canal file is running out of lifespan.

[0047] In this optional embodiment, if the remaining lifespan of the root canal file is insufficient, an alarm is issued to medical staff. The intelligent management terminal of this embodiment is equipped with a multi-color LED light module, which can issue warnings to medical staff via the LED light module, or provide prompts through the human-computer interaction interface of the intelligent management terminal.

[0048] In another optional embodiment, to provide more intuitive and efficient clinical decision-making support for the calculated remaining lifespan information of the root canal file, the present invention may further include multi-dimensional remaining lifespan visualization and decision support functions. Specifically, after obtaining the target remaining lifespan, the remaining lifespan information of the target root canal file is dynamically displayed graphically on the human-computer interaction interface of the intelligent management terminal of the root canal treatment device. Display methods include, but are not limited to: Progress bar format: A colored progress bar that goes from full (representing brand new) to empty (representing depleted). The current fill percentage corresponds to the target remaining lifespan percentage. The color can gradient from green (high remaining lifespan) to yellow (medium) and then to red (low remaining lifespan).

[0049] Numerical display and color coding: Directly display the number "Remaining lifespan: XX%" and match it with the corresponding background color or font color according to the value range.

[0050] Historical wear curve: Plot the cumulative damage growth curve of this root canal file during each treatment, and mark the current treatment position so that doctors can intuitively understand its usage history.

[0051] Estimated remaining uses: Based on the average damage rate of the current treatment process (cumulative damage / treatment time), combined with the target remaining lifespan percentage, this estimate is made of the approximate number of treatments or the estimated total working time that the root canal file can safely complete under similar operating intensity, and is displayed as a prompt message.

[0052] In addition, a knowledge base on the lifespan of root canal files can be established and maintained. This knowledge base links different root canal file models, different treatment stages (such as coronal preparation, mid-section preparation, and apical preparation), different tooth positions (anterior teeth, premolars, and molars), and typical torque / speed patterns, along with corresponding empirical lifespan reference values.

[0053] During treatment, the system analyzes the currently acquired torque / speed patterns in real time and matches them with a knowledge base. When the system identifies that the current operation may be in a high-damage-consumption phase (e.g., torque remains high and fluctuates wildly, matching a typical pattern of preparation for apical stenosis), it can provide contextual prompts on the interface. For example: "Currently in a high-torque preparation phase, instrument lifespan is being consumed at an accelerated rate. It is recommended to intermittently exit the examination and flush, or assess whether a smaller file is needed." When the target remaining lifespan is lower than the first preset threshold (e.g., 20%), in addition to issuing an alarm, the system can automatically pop up a device replacement suggestion on the interface and display the recommended next file number that matches the model of root canal file (based on the standard treatment sequence), or prompt the doctor to check the spare files in the device packaging.

[0054] This extended implementation transforms backend-calculated lifespan data into intuitive visual information and context-aware decision support at the front end, achieving a leap from "data computation" to "clinical insight." It reduces the cognitive burden on physicians to understand and apply complex lifespan models, enabling them to perceive instrument status in real time during treatment, proactively adjust operating strategies, and prepare for instrument replacements in advance. This shifts the risk control point for root canal file breakage forward, optimizing the safety and smoothness of the treatment process.

[0055] In yet another optional embodiment, the root canal treatment device further includes an image acquisition device; Before acquiring the real-time torque data collected by the reamer motor during the current root canal treatment, the root canal file life calculation method for root canal treatment equipment disclosed in this embodiment of the invention further includes: Acquire the instrument identification image of the target root canal file; the instrument identification image is obtained by the image acquisition device capturing the instrument identification of the target root canal file. The target root canal file is identified by its instrument identification image to obtain its identification information. Based on the identity information of the root canal file, the parameters are matched in the preset root canal file parameter database to obtain the standard working parameters corresponding to the target root canal file; the root canal file parameter database includes either a local parameter database or a cloud parameter database; The standard operating parameters are sent to the mechanical reamer motor so that the mechanical reamer motor can drive the target root canal file to work according to the standard operating parameters.

[0056] The image acquisition device is located in the intelligent management terminal. The instrument identification of the root canal file can be specifically represented by graphic labels such as QR codes or barcodes. After medical staff place the root canal file in the camera area of ​​the image acquisition device, the device is triggered to capture an image.

[0057] In this optional embodiment, medical staff only need to perform a scanning action, and the root canal treatment equipment can complete the automatic parameter configuration process, so that the mechanical expansion motor reaches the optimal ready state within a few seconds, thereby realizing the non-intrusive configuration of equipment parameters.

[0058] In another optional embodiment, after calculating the remaining life of the target root canal file based on the current cumulative damage data, the root canal file life calculation method for root canal treatment equipment disclosed in this embodiment of the invention further includes: The treatment process data is encrypted and encapsulated to obtain an encrypted data packet; the treatment process data includes the root canal file identification information, real-time torque data, current cumulative damage data, and target remaining lifespan; The encrypted data packet is uploaded to a pre-set cloud-based treatment database for storage.

[0059] In this optional embodiment, after a single treatment session, the intelligent management terminal encrypts and encapsulates the local treatment process data and uploads it to a cloud database. The database provides associated queries based on root canal file identifiers or patient identities, and can reproduce the complete process of any root canal file use, including its mechanical properties and corresponding state changes, forming a "playback" digital twin archive of instruments. This provides an immutable and objective data chain for accident analysis, operational standardization assessment, instrument process improvement, and physician training.

[0060] Furthermore, in addition to root canal file identification information, real-time torque data, current cumulative damage data, and target remaining lifespan, treatment process data may also include system event logs and alarm prompts related to the treatment process.

[0061] In another optional embodiment, based on a large amount of health record data of the same type of root canal file, the system backend can periodically perform group performance analysis, such as: 1. Calculating the average lifespan (in terms of cumulative damage value or number of treatments) and its distribution of the root canal file of this type in actual clinical practice, and comparing it with laboratory data provided by the manufacturer; 2. Analyzing the differences in the average lifespan of the same type of file used by different doctors or different clinics, and identifying factors that may be related to operating habits; 3. Correlating treatment outcome data (such as root canal filling quality assessment, which needs to be integrated with other systems) to explore the potential correlation between instrument usage status (such as the initial remaining lifespan of this treatment, the damage intensity of this treatment) and treatment prognosis (this analysis must be conducted in accordance with ethical and data safety regulations).

[0062] This optional embodiment extends the lifespan calculation from a single treatment to the entire service life of the device, providing a refined management tool for individual devices. More importantly, by aggregating massive amounts of real-world device usage data, it creates significant reference value for device manufacturers to improve product design, for medical institutions to optimize consumable procurement and inventory management, and for clinical training to provide evidence-based best practice cases.

[0063] Example 2 Please see Figure 2 , Figure 2 This is a schematic diagram of a root canal file life calculation system for root canal treatment equipment disclosed in an embodiment of the present invention. Figure 2 The system shown can be used to perform the method described in Embodiment 1. This system improves the accuracy of assessing the remaining lifespan of root canal files. Furthermore, the system can be integrated into the control system of a root canal treatment device. The root canal treatment device includes a mechanical reamer motor, such as... Figure 2 As shown, the root canal file life calculation system for root canal treatment equipment disclosed in this embodiment of the invention includes, but is not limited to: The torque data acquisition module 201 is used to acquire real-time torque data collected by the mechanical reamer motor during the current root canal treatment process; the real-time torque data is the rotational torque data of the target root canal file connected to the mechanical reamer motor. The cumulative damage calculation module 202 is used to perform cumulative damage calculation based on real-time torque data to obtain the current cumulative damage data of the target root canal file during the current root canal treatment process; The remaining life calculation module 203 is used to calculate the remaining life of the target root canal file based on the current cumulative damage data, and obtain the target remaining life.

[0064] It should be noted that the root canal treatment device in this embodiment of the invention also includes an intelligent management terminal. The intelligent management terminal communicates with the mechanical reamer motor via wired or wireless means. The intelligent management terminal can receive data collected by the mechanical reamer motor and process the data to calculate the remaining lifespan of the root canal file.

[0065] In this embodiment of the invention, real-time torque data collected by the reamer motor during the current root canal treatment is acquired; then, damage accumulation calculation is performed based on the real-time torque data to obtain the current cumulative damage data of the target root canal file during the current root canal treatment; finally, the remaining lifespan of the target root canal file is calculated based on the current cumulative damage data to obtain the target remaining lifespan. By acquiring the real-time torque of the root canal file to quantify the usage intensity of the root canal file, and calculating the instrument damage of the root canal file based on the real-time torque, the remaining lifespan of the root canal file can be assessed. Compared with simply accumulating "usage time" to assess the lifespan of the root canal file, the assessment of the remaining lifespan of the root canal file has higher accuracy and reliability.

[0066] In an optional embodiment, the cumulative damage calculation module 202 performs cumulative damage calculation based on real-time torque data to obtain the current cumulative damage data of the target root canal file during the current root canal treatment process. The specific methods include: The real-time torque data is divided into time series to obtain a set of time segments. The set of time segments includes multiple target time segments. Each target time segment has a corresponding target torque value. The target torque value is used to characterize the rotational torque of the target root canal file in the target time segment corresponding to the target torque value. For each target time segment in the time segment set, the instrument damage of the target root canal file in the target time segment is calculated based on the target torque value corresponding to the target time segment, and the segment damage value corresponding to the target time segment is obtained. The damage values ​​of all target time segments are summed to obtain the current cumulative damage data of the target root canal file during the current root canal treatment process.

[0067] It should be noted that for a specific type of root canal file, the time it can withstand a constant torque before fatigue fracture is limited, and this "limited duration" has a highly non-linear negative correlation with the torque value. Within the same time frame, the instrument damage suffered by a root canal file under high torque conditions is significantly greater than that under low torque conditions.

[0068] Through extensive destructive testing, the average limiting time L_i of a certain type of root canal file under different constant torques T_i can be obtained. For example, some experimental data for a certain type of root canal file are as follows: At a torque of 0.3 N·cm, the average limit duration is 360 seconds; At a torque of 0.6 N·cm, the average limit duration is 200 seconds; At a torque of 1.0 N·cm, the average limit duration is 150 seconds; ... After obtaining the experimental data, the torque T is plotted on the x-axis and the extreme duration L is plotted on the y-axis. The data points (T_i, L_i) are then fitted with a curve to obtain the "torque-extreme duration" characteristic curve of this type of file. Its mathematical expression can be written as: L=F(T), where F(T) is a nonlinear decay function determined by the experimental data. It can usually be expressed as a power function or an exponential function, such as L=A*T^(-B), where A and B are material constants determined by fitting.

[0069] In this optional embodiment, the damage effect of varying torque is mapped onto the aforementioned characteristic curve for calculation. The real-time torque data is divided, with the torque of the root canal file considered constant within extremely short time segments, thereby calculating the damage suffered by the root canal file during this period. The damage suffered by the root canal file in all time segments is then summed to obtain the total damage suffered by the root canal file during this treatment.

[0070] The method for calculating the remaining lifespan of root canal files in this invention reflects the nonlinear core principle that "damage caused by high torque is much faster than that caused by low torque," realizing a shift from "timekeeping" to "damage measurement." Compared with simply accumulating "usage time" to evaluate the lifespan of root canal files, the accuracy and reliability of evaluating the remaining lifespan of root canal files are significantly improved.

[0071] In another optional embodiment, for each target time segment in the time segment set, the cumulative damage calculation module 202 calculates the instrument damage of the target root canal file within the target time segment based on the target torque value corresponding to the target time segment. The specific method for obtaining the segment damage value corresponding to the target time segment includes: For each target time segment in the time segment set, the target torque value corresponding to the target time segment is matched with the target torque value according to the pre-stored torque-duration database to obtain the target limit duration corresponding to the target torque value. The ratio of the duration of the target time segment to the target limit duration is calculated to obtain the segment damage value corresponding to the target time segment. The target limit duration is the average limit working time of other root canal files of the same model as the target root canal file at the target torque value.

[0072] In this optional embodiment, the torque-duration database stores data on the maximum operating time of different types of root canal files under multiple constant torques. For the nth target time segment, the average maximum operating time of the target root canal file at the target torque value T_n can be obtained by querying the torque-duration database as L_current=F(T_n). The segment corresponding to this target time segment is D_n=Δt_n / L_current, where Δt_n represents the duration of the nth target time segment.

[0073] In one optional embodiment, the remaining lifespan calculation module 203 calculates the remaining lifespan of the target root canal file based on the current cumulative damage data. The specific methods for obtaining the target remaining lifespan include: Retrieve pre-stored historical cumulative damage data; historical cumulative damage data is the cumulative damage data of the target root canal file during historical root canal treatments; Calculate the sum of the current cumulative damage data and the historical cumulative damage data to obtain the target cumulative damage value; Calculate the difference between the target cumulative damage value and the target cumulative damage value, and convert it to a percentage to obtain the target remaining lifespan.

[0074] In this optional embodiment, the target cumulative damage value is: D_total = D_past + Σ(Δt_i / F(T_i)), where T_i is the target torque value corresponding to the i-th target time segment, and D_past is the historical cumulative damage data. It is understood that if the target root canal file has not been used before, the historical cumulative damage data is zero.

[0075] In another optional embodiment, to further improve the comprehensiveness and clinical applicability of the assessment of the remaining lifespan of root canal files, the embodiments of the present invention may also include the synchronous acquisition and fusion analysis of rotational speed data during the use of root canal files. Specifically, the mechanical reamer motor of the root canal treatment device can not only acquire real-time torque data of the target root canal file, but also synchronously acquire its real-time rotational speed data. Before calculating the cumulative damage based on the real-time torque data, the following operations are also included: Acquire real-time rotation speed data collected by the reamer motor during the current root canal treatment process; the real-time rotation speed data is the rotational speed data of the target root canal file connected to the reamer motor at the corresponding time point; Based on real-time torque and speed data, cumulative composite stress damage is calculated to obtain the current cumulative composite damage data of the target root canal file during the current root canal treatment process.

[0076] In this alternative implementation, the fatigue damage experienced by root canal files during actual operation is not determined solely by torque. Variations in rotational speed affect the stress cycle frequency, frictional heating effect, and fretting wear mechanisms within the material. Higher rotational speeds may lead to faster fatigue accumulation at the same torque, especially when the file encounters local resistance within the root canal or experiences slight bending; the coupling effect of centrifugal force and alternating stress exacerbates the damage process. Therefore, introducing a rotational speed parameter allows for a more precise characterization of the dynamic working state of the root canal file.

[0077] In yet another alternative embodiment, please refer to Figure 3 , Figure 3 This is a schematic diagram of another root canal file life calculation system for root canal treatment equipment disclosed in an embodiment of the present invention. Figure 3 As shown in the embodiment of the present invention, a root canal file life calculation system for root canal treatment equipment further includes: The remaining lifespan comparison module 204 is used to calculate the remaining lifespan of the target root canal file based on the current cumulative damage data in the remaining lifespan calculation module 203, and after obtaining the target remaining lifespan, compare the target remaining lifespan with a preset lifespan threshold to obtain a lifespan comparison result. The remaining life alarm module 205 is used to issue an alarm prompt to the medical staff using the root canal treatment equipment that the root canal file is not alive if the target remaining life is less than the preset life threshold.

[0078] In this optional embodiment, if the remaining lifespan of the root canal file is insufficient, an alarm is issued to medical staff. The intelligent management terminal of this embodiment is equipped with a multi-color LED light module, which can issue warnings to medical staff via the LED light module, or provide prompts through the human-computer interaction interface of the intelligent management terminal.

[0079] In another optional embodiment, to provide more intuitive and efficient clinical decision-making support for the calculated remaining lifespan information of the root canal file, the present invention may further include multi-dimensional remaining lifespan visualization and decision support functions. Specifically, after obtaining the target remaining lifespan, the remaining lifespan information of the target root canal file is dynamically displayed graphically on the human-computer interaction interface of the intelligent management terminal of the root canal treatment device. Display methods include, but are not limited to: Progress bar format: A colored progress bar that goes from full (representing brand new) to empty (representing depleted). The current fill percentage corresponds to the target remaining lifespan percentage. The color can gradient from green (high remaining lifespan) to yellow (medium) and then to red (low remaining lifespan).

[0080] Numerical display and color coding: Directly display the number "Remaining lifespan: XX%" and match it with the corresponding background color or font color according to the value range.

[0081] Historical wear curve: Plot the cumulative damage growth curve of this root canal file during each treatment, and mark the current treatment position so that doctors can intuitively understand its usage history.

[0082] Estimated remaining uses: Based on the average damage rate of the current treatment process (cumulative damage / treatment time), combined with the target remaining lifespan percentage, this estimate is made of the approximate number of treatments or the estimated total working time that the root canal file can safely complete under similar operating intensity, and is displayed as a prompt message.

[0083] In addition, a knowledge base on the lifespan of root canal files can be established and maintained. This knowledge base links different root canal file models, different treatment stages (such as coronal preparation, mid-section preparation, and apical preparation), different tooth positions (anterior teeth, premolars, and molars), and typical torque / speed patterns, along with corresponding empirical lifespan reference values.

[0084] During treatment, the system analyzes the currently acquired torque / speed patterns in real time and matches them with a knowledge base. When the system identifies that the current operation may be in a high-damage-consumption phase (e.g., torque remains high and fluctuates wildly, matching a typical pattern of preparation for apical stenosis), it can provide contextual prompts on the interface. For example: "Currently in a high-torque preparation phase, instrument lifespan is being consumed at an accelerated rate. It is recommended to intermittently exit the examination and flush, or assess whether a smaller file is needed." When the target remaining lifespan is lower than the first preset threshold (e.g., 20%), in addition to issuing an alarm, the system can automatically pop up a device replacement suggestion on the interface and display the recommended next file number that matches the model of root canal file (based on the standard treatment sequence), or prompt the doctor to check the spare files in the device packaging.

[0085] This extended implementation transforms backend-calculated lifespan data into intuitive visual information and context-aware decision support at the front end, achieving a leap from "data computation" to "clinical insight." It reduces the cognitive burden on physicians to understand and apply complex lifespan models, enabling them to perceive instrument status in real time during treatment, proactively adjust operating strategies, and prepare for instrument replacements in advance. This shifts the risk control point for root canal file breakage forward, optimizing the safety and smoothness of the treatment process.

[0086] In yet another optional embodiment, the root canal treatment device further includes an image acquisition device; Please see Figure 4 , Figure 4 This is a schematic diagram of another root canal file life calculation system for root canal treatment equipment disclosed in this embodiment of the invention. Figure 4 As shown in the embodiment of the present invention, a root canal file life calculation system for root canal treatment equipment further includes: The identification image acquisition module 206 is used to acquire the instrument identification image of the target root canal file before the torque data acquisition module 201 acquires the real-time torque data collected by the reamer motor during the current root canal treatment. The identification module 207 is used to identify the target root canal file based on the instrument identification image to obtain the root canal file identification information of the target root canal file. The working parameter matching module 208 is used to match parameters in a preset root canal file parameter database based on the root canal file's identity information to obtain the standard working parameters corresponding to the target root canal file; the root canal file parameter database includes either a local parameter database or a cloud parameter database; The working parameter sending module 209 is used to send standard working parameters to the mechanical expansion motor so that the mechanical expansion motor drives the target root canal file to work according to the standard working parameters.

[0087] The image acquisition device is located in the intelligent management terminal. The instrument identification of the root canal file can be specifically represented by graphic labels such as QR codes or barcodes. After medical staff place the root canal file in the camera area of ​​the image acquisition device, the device is triggered to capture an image.

[0088] In this optional embodiment, medical staff only need to perform a scanning action, and the root canal treatment equipment can complete the automatic parameter configuration process, so that the mechanical expansion motor reaches the optimal ready state within a few seconds, thereby realizing the non-intrusive configuration of equipment parameters.

The treatment process data includes the root canal file identification information, real-time torque data, current cumulative damage data and target remaining life. The data packet upload module 211 is used to upload encrypted data packets to a preset cloud treatment database for storage.

[0090] In this optional embodiment, after a single treatment session, the intelligent management terminal encrypts and encapsulates the local treatment process data and uploads it to a cloud database. The database provides associated queries based on root canal file identifiers or patient identities, and can reproduce the complete process of any root canal file use, including its mechanical properties and corresponding state changes, forming a "playback" digital twin archive of instruments. This provides an immutable and objective data chain for accident analysis, operational standardization assessment, instrument process improvement, and physician training.

[0091] Furthermore, in addition to root canal file identification information, real-time torque data, current cumulative damage data, and target remaining lifespan, treatment process data may also include system event logs and alarm prompts related to the treatment process.

[0092] In another optional embodiment, based on a large amount of health record data of the same type of root canal file, the system backend can periodically perform group performance analysis, such as: 1. Calculating the average lifespan (in terms of cumulative damage value or number of treatments) and its distribution of the root canal file of this type in actual clinical practice, and comparing it with laboratory data provided by the manufacturer; 2. Analyzing the differences in the average lifespan of the same type of file used by different doctors or different clinics, and identifying factors that may be related to operating habits; 3. Correlating treatment outcome data (such as root canal filling quality assessment, which needs to be integrated with other systems) to explore the potential correlation between instrument usage status (such as the initial remaining lifespan of this treatment, the damage intensity of this treatment) and treatment prognosis (this analysis must be conducted in accordance with ethical and data safety regulations).

[0093] This optional embodiment extends the lifespan calculation from a single treatment to the entire service life of the device, providing a refined management tool for individual devices. More importantly, by aggregating massive amounts of real-world device usage data, it creates significant reference value for device manufacturers to improve product design, for medical institutions to optimize consumable procurement and inventory management, and for clinical training to provide evidence-based best practice cases.
