Description

Technical Field

[0001] This invention belongs to the field of oral medicine technology, and in particular relates to a method and system for monitoring the wear and tear of medical files. Background Technology

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

[0003] Endodontic therapy is a common surgical procedure for treating pulp necrosis, pulp infection, periapical infection, and related lesions. During the treatment, the dentist uses specialized medical files to remove infected dentin and pulp tissue through rotation or manual manipulation, achieving the goals of cleaning, disinfecting, and filling the root canal. In recent years, rotary medical systems combined with medical files, due to their flexibility and shape memory properties, have been widely used in endodontic therapy.

[0004] However, existing technologies still have significant shortcomings in the management, monitoring, and condition assessment of medical filaments, mainly in the following aspects:

[0005] (1) Clinical assessment of the wear status of medical files relies entirely on the doctor's experience, the number of times the medical file is used, or the doctor's visual inspection. It is impossible to quantify the microscopic fatigue damage of the medical file, let alone accurately determine whether the medical file is in a critical state of fracture. If the medical file breaks in the root canal during use, it will cause persistent root canal system infection, and may even lead to the need for tooth extraction.

[0006] (2) During root canal treatment, the operating parameters of medical files (such as applied torque, rotation speed, and cumulative working time) are the key basis for assessing their wear condition. However, these operating parameters are enclosed in the main control chip and lack an external output interface. Doctors cannot know the specific parameter data and can only rely on subjective experience to judge the condition of the medical files. Therefore, overuse or premature replacement may occur.

[0007] (3) Medical files come in a variety of models and are frequently used repeatedly and interchangeably. Existing technology lacks a unique identifier and information association mechanism for each medical file, making it impossible to accurately distinguish between medical files from different manufacturers, models, and production batches. It is even more difficult to trace the complete usage history of a single medical file (such as the number of times it was used and the operating conditions for each use). This makes it difficult for doctors to accurately determine the cumulative usage intensity and wear of a specific medical file, increasing the possibility of treatment risks caused by the use of excessively worn medical files. Summary of the Invention

[0008] To overcome the shortcomings of the prior art, the present invention provides a method and system for monitoring the wear status of medical files, which can monitor the working status of medical files in real time during root canal treatment, providing a basis for judging the next use of medical files.

[0009] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0010] The first aspect of this invention provides a method for monitoring the wear and tear of a medical file.

[0011] A method for monitoring the wear and tear of a medical file, comprising:

[0012] A composite code containing basic information about the medical file is embedded in the non-working segment at the base of the medical file;

[0013] The composite code is identified based on the data reading method built into the data reading unit, and the medical file that is successfully identified by the composite code is decoded and verified.

[0014] If the decoding verification is valid, the operating parameters of the medical file during operation will be acquired and parsed in real time and uploaded to the server; if the decoding verification is invalid, an alarm will be triggered by a buzzer.

[0015] The computing unit within the server evaluates the real-time wear status of the medical file based on the obtained operating parameters through fatigue damage accumulation calculation, and generates visualized medical file wear monitoring results.

[0016] Furthermore, the composite code includes a manufacturer code, model code, production batch, and unique serial number corresponding to the medical file.

[0017] Furthermore, the composite code is identified based on the data reading method built into the data reading unit, including: first, inserting the medical file to be identified for laser alignment detection; if the alignment is successful, information is collected and preprocessing is performed, and the preprocessed information is used as the basis for decoding verification; if the alignment fails, an alarm is triggered by a buzzer.

[0018] Furthermore, the operation parameters of the medical file during operation are acquired and analyzed in real time, including: reverse analysis of the communication protocol of the root canal motor main control chip based on a high-speed digital isolator, and direct interception and analysis of the operation parameters of the medical file during operation; wherein, the high-speed digital isolator is connected in parallel to the communication bus of the root canal motor main control chip.

[0019] Furthermore, the real-time wear status of the medical file is evaluated through fatigue damage accumulation calculation, and a visualized medical file wear monitoring result is generated, including: first, calculating the real-time wear rate and stress value induced by the internal components of the medical file based on the obtained operating parameters; then, determining the current wear degree and energy consumption of the medical file based on the obtained real-time wear rate, and determining the cumulative fatigue damage of the medical file based on the obtained stress value; simultaneously, predicting the service life of the medical file based on the obtained real-time wear rate; finally, visualizing all calculation results and storing them in the unique identification code corresponding to the medical file.

[0020] A second aspect of the present invention provides a medical file wear status monitoring system.

[0021] A medical file wear status monitoring system includes: a medical file, a root canal motor, and a server; wherein the root canal motor controls the working status of the medical file through an internal main control chip.

[0022] Furthermore, a data reading unit is integrated on the inner wall of the slot of the root canal motor, which is used to identify the composite code based on the built-in data reading method, and to decode and verify the medical file that has successfully identified the composite code.

[0023] Furthermore, a high-speed digital isolator is installed on the control board where the main control chip is located inside the root canal motor. The high-speed digital isolator and the main control chip are connected via a communication bus. The high-speed digital isolator is used to acquire and parse the operating parameters of the medical file in real time and upload them to the server.

[0024] Furthermore, the server integrates an in-server computing unit, which is used to evaluate the real-time wear status of the medical file through fatigue damage accumulation calculation based on the obtained operating parameters, and generate visualized medical file wear monitoring results.

[0025] Furthermore, a buzzer is installed on the outer wall of the root canal motor, and the working state of the buzzer is controlled by the data reading unit.

[0026] The above one or more technical solutions have the following beneficial effects:

[0027] (1) After acquiring and parsing the operating parameters of the medical file during operation, the present invention uploads them to the server. The computing unit in the server calculates and quantifies the real-time wear status of the medical file based on the obtained operating parameters through fatigue damage accumulation calculation, and generates a visualized medical file wear monitoring result, thereby providing doctors with a more scientific and objective basis for judging the suitability of the medical file.

[0028] (2) This invention connects a high-speed digital isolator in parallel on the communication bus of the root canal motor main control chip. By reverse-engineering the communication protocol, it intercepts and parses the operating parameters, realizing the real-time acquisition and uploading of key operating parameters such as torque, speed, and cumulative working time. Doctors can judge the usage status of the medical file based on these objective parameters, effectively avoiding overuse or premature replacement due to subjective experience misjudgment.

[0029] (3) This invention embeds a composite code containing the manufacturer's code, model code, production batch number, and unique serial number into the non-working section of the root of the medical file, and uses the data reading unit in the root canal motor slot to identify and verify the code, thereby achieving a unique identifier and information binding for each medical file. At the same time, combined with the server's records of operating parameters and usage history, the number of times a single medical file has been used, operating conditions, and other information can be fully traced, effectively distinguishing the attributes of different medical files, thereby reducing the treatment risks caused by misuse, mixing, or overuse.

[0030] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0035] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations of the present invention.

[0036] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0037] Example 1

[0038] This embodiment discloses a method for monitoring the wear and tear of medical files.

[0039] like Figure 1 As shown, a method for monitoring the wear and tear of a medical file includes:

[0040] Step S1: Embed a composite code containing basic information about the medical file into the non-working segment at the base of the medical file;

[0041] Step S2: Identify the composite code based on the data reading mode built into the data reading unit, and decode and verify the medical file that has been successfully identified by the composite code;

[0042] Step S3: If the decoding verification is valid, the operating parameters of the medical file during operation will be acquired and parsed in real time and uploaded to the server; if the decoding verification is invalid, an alarm will be triggered by a buzzer.

[0043] Step S4: The computing unit inside the server evaluates the real-time wear status of the medical file by fatigue damage accumulation calculation based on the obtained operating parameters, and generates a visualized medical file wear monitoring result.

[0044] Based on the above process, this invention can monitor the working status of medical files in real time during root canal treatment, providing a basis for determining the next steps in using the medical files. To facilitate understanding of the technical solution of this invention, the specific implementation methods of this invention will be further explained and described below.

[0045] In step S1, a composite code containing basic information about the medical file is embedded in the non-working segment at the base of the medical file.

[0046] Using micron-level laser etching technology, a 20-digit composite code (containing letters, numbers, and a check digit, and compatible with the ISO / IEC 18004 standard) is embedded 2mm (non-working section) at the base of the nickel-titanium medical file. Specifically, the embedded composite code includes: manufacturer code (3 digits), model code (4 digits), production batch (6 digits), and unique serial number (7 digits).

[0047] In step S2, the composite code is identified based on the data reading mode built into the data reading unit, and the medical file that has been successfully identified by the composite code is decoded and verified.

[0048] Identification is performed using a data reading unit installed on the inner wall of the root canal motor slot. Specifically, the data reading unit uses a built-in optical data reading method to identify the composite code and decodes and verifies the medical file that has successfully identified the composite code.

[0049] like Figure 2As shown, in actual implementation, firstly, a medical file to be identified is inserted for laser alignment detection (the specific insertion path of the medical file is at a 90° angle to the data reading unit on the inner wall of the root canal motor slot). If alignment is successful, information is collected and preprocessing is performed, using the preprocessed information as the basis for decoding verification. If alignment fails, an alarm is triggered by a buzzer. The medical file is connected to the motor and cannot be manually separated; after connection, the motor latches into the slot at the tail of the medical file and cannot be manually separated, indicating successful alignment. Preprocessing can be achieved through focusing and identifying a unique code. It should be noted that preprocessing is not a key technical point of this invention and can be implemented using existing technology; therefore, this embodiment does not impose specific limitations on it.

[0050] As an optional embodiment, an integrated CMOS image sensor (model OV2740, resolution 1600×1200) is used as the data reading unit for optical data reading, to read composite codes. Simultaneously, to ensure reading clarity, a ring-shaped LED supplementary light array (630nm red light wavelength, adjustable illumination) is added around the integrated CMOS image sensor to improve reading clarity, facilitating the identification of information related to the medical file currently being used by the root canal motor.

[0051] In step S3, if the decoding verification is valid, the operating parameters of the medical file during operation are acquired and parsed in real time and uploaded to the server; if the decoding verification is invalid, an alarm is triggered by a buzzer.

[0052] A high-speed digital isolator, model ADI ADuM3160, is connected in parallel to the communication bus (SPI or CAN bus) of the root canal motor main control chip. The high-speed digital isolator directly intercepts and parses the raw data stream output by its internal sensor (integrated CMOS image sensor) by reverse-analyzing the communication protocol of the root canal motor main control chip. This data is used to read information such as the torque, speed and working time set by the physician on the medical file by the root canal motor.

[0053] In step S4, the computing unit within the server evaluates the real-time wear status of the medical file based on the obtained operating parameters through fatigue damage accumulation calculation, and generates visualized medical file wear monitoring results. This can be achieved through the following methods:

[0054] 1) Calculate the real-time wear rate of the medical file and the stress value induced inside the medical file based on the obtained operating parameters.

[0055] The initial wear rate W of a medical file depends primarily on the applied axial force F and the cumulative operating time t, and can be characterized by an empirical formula, namely:

[0056] ;

[0057] Where k is a material constant, and n and m are empirical parameters. This formula quantifies the direct impact of the surgeon's intensity and duration of operation on the material removal rate, and forms the basis for subsequent calculations of wear depth and energy.

[0058] In addition, a linear elastic model can be used to evaluate the deformation behavior of medical files under stress, namely:

[0059] ;

[0060] Where σ represents stress, ε represents strain, and E represents the elastic modulus. This relationship is used to calculate the stress level (σ_i) induced inside the medical file by the operating load, and is also a key input for fatigue damage analysis.

[0061] 2) Determine the current wear level and energy consumption of the medical file based on the obtained real-time wear rate, and determine the cumulative fatigue damage of the medical file based on the obtained stress value.

[0062] On the one hand, medical files undergo fatigue under cyclic loading (such as rotation and lifting). By integrating the stress information from each cycle, the cumulative fatigue damage can be calculated, i.e.:

[0063] ;

[0064] Where N represents the effective stress cycle number, σ_i represents the stress in the i-th cycle (calculated from the stress-strain relationship and real-time load), σ_f represents the fatigue limit of the material, and p represents the material constant of the medical file (nickel-titanium alloy). This model integrates the load history (σ_i), material fatigue characteristics (σ_f, p), and the number of operations (N) to dynamically reflect the degree of micro-damage accumulation inside the medical file caused by cyclic stress. When the D value approaches 1, it indicates a significant increase in the risk of fatigue failure.

[0065] On the other hand, based on the real-time wear rate W, the current wear depth of critical parts of the medical file (such as the cutting edge) can be calculated:

[0066] ;

[0067] This indicator directly reflects the loss of geometric dimensions in medical files, which directly affects their cutting efficiency.

[0068] Meanwhile, the mechanical energy consumed by wear during the entire operation is obtained by integrating the wear rate, that is:

[0069] ;

[0070] This energy value can be used as an auxiliary indicator to assess the overall working strength and material durability of medical files.

[0071] Wear is the result of the combined action of multiple mechanisms (such as abrasive wear, adhesive wear, and fatigue spalling), and the total wear can be expressed as:

[0072] ;

[0073] Here, \(W_{fatigue}\) is associated with the damage \(D\) and is used to reflect the contribution of fatigue damage to macroscopic wear.

[0074] 3) Predict the service life of the medical file according to the obtained real-time wear rate.

[0075] A. Wear life prediction (\(L\)): Based on the current wear rate (\(W\)) and the initial effective thickness (\(C\)) of the medical file material, predict its remaining service life:

[0076] ;

[0077] B. Real-time wear state assessment (\(S\)): Combining the current wear depth (\(d\)) and the maximum allowable wear depth (\(D_{max}\)) of the material, calculate the normalized wear state index, that is:

[0078] ;

[0079] Among them, the value of \(S\) (\(0 < S < 1\)) indicates the wear severity of the medical file in real time, and a strong replacement signal is issued when \(S\) is close to 1.

[0080] C. Failure probability (\(P_f\)) and reliability (\(R(t)\)): Based on the failure rate (\(\lambda\)), the model can evaluate the failure probability and reliability of the medical file within time \(t\), that is:

[0081] ;

[0082] ;

[0083] Among them, \(\lambda\) is a function of the wear state \(S\) or damage \(D\), reflecting the influence of the state on the failure rate.

[0084] D. Adaptive control strategy (\(F_{control}\)): To achieve optimal operation and extend the life of the medical file, based on the evaluated wear state (for example, the error \(e\) can be set as the difference between the target wear rate and the actual wear rate, or the difference between the target state \(S_{target}\) and the actual \(S\)), design a feedback control algorithm to adjust the operation parameters (such as the applied force \(F\)):

[0085] ;

[0086] Among them, , , To control gain, this controller is designed to dynamically optimize operating parameters, minimizing wear rate and damage accumulation while ensuring therapeutic effectiveness, and maintaining the medical file in ideal working condition.

[0087] Visualize all calculation results. After obtaining the calculation results, generate visualized medical file wear monitoring results via a server and display them on a monitor. The server that can be used includes, but is not limited to, a web server, a local computer, or a personal mobile data terminal.

[0088] Example 2

[0090] A medical file wear status monitoring system includes: a medical file, a root canal motor, and a server; wherein the root canal motor controls the working status of the medical file through an internal main control chip.

[0091] Furthermore, a data reading unit is integrated on the inner wall of the slot of the root canal motor, which is used to identify the composite code based on the built-in data reading method, and to decode and verify the medical file that has successfully identified the composite code.

[0092] Furthermore, a high-speed digital isolator is installed on the control board where the main control chip is located inside the root canal motor. The high-speed digital isolator and the main control chip are connected via a communication bus. The high-speed digital isolator is used to acquire and parse the operating parameters of the medical file in real time and upload them to the server.

[0093] Furthermore, the server integrates an in-server computing unit, which is used to evaluate the real-time wear status of the medical file through fatigue damage accumulation calculation based on the obtained operating parameters, and generate visualized medical file wear monitoring results.
