[0002] Medical device management refers to the comprehensive management process of various medical devices used in hospitals, operating rooms, and supply centers throughout their lifecycle, including planning, configuration, deployment, use, maintenance, traceability, and disposal. Its core goal is to ensure the safety, usability, and compliance of devices in clinical use, and to prevent medical risks caused by incorrect device use, unclear status, or unclear responsibility.

[0003] However, existing surgical instrument management systems generally lack a unique identification mechanism based on instrument attributes, making it impossible to accurately trace instruments throughout their entire lifecycle. This results in isolated status information and a broken chain of responsibility during key steps such as instrument configuration, transfer, handover, and inventory. This leads to frequent inventory errors, unclear handovers, and mismatched permissions in the management process, increasing medical safety risks and operational costs. Therefore, the industry faces the challenge of achieving multi-dimensional perception and correlation of global status information for surgical instruments within the full-process management scenario to improve the traceability accuracy of surgical instrument management.

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] The embodiment of the present application provides a refined management method and system for surgical instruments, the core of which is to generate a traceability identification code based on the configuration attributes of the surgical instrument; to associate the traceability identification code with the instrument status data of the surgical instrument in different scenarios in real time to obtain operation association information; to obtain the dynamic flow path of the surgical instrument from the instrument supply terminal, to determine the handover constraint label of the surgical instrument during the handover process based on the dynamic flow path and the operation association information, and then to determine the comparison interaction sequence of the surgical instrument in the inventory link based on the handover constraint label; to obtain the management evaluation log of the instrument inventory operator, to determine the allocation verification cycle of the surgical instrument between the supply center and the operating room based on the management evaluation log, and then to synchronously verify the disposal authority level of the surgical instrument based on the allocation verification cycle to generate a collaborative traceability indicator for the surgical instrument in the verification link; and to perform targeted closed-loop management of the surgical instrument based on the comparison interaction sequence and the collaborative traceability indicator.

[0022] Example 1: In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods. Figure 1 As shown in FIG. 1 , this figure is an exemplary flow chart of a refined management method for surgical instruments according to this embodiment of the present application, and the management method includes the following steps: In step S1, a traceability identification code is generated based on the configuration attributes of the surgical instrument; the traceability identification code is associated with the instrument status data of the surgical instrument in different scenarios in real time to obtain operation association information.

[0023] In specific implementation, the generation of traceability identification codes based on the configuration attributes of surgical instruments can be achieved in the following manner: first, establish an instrument configuration attribute model with fields including instrument number, name, category, material, size, applicable department, functional use, cleaning and sterilization requirements, etc., to ensure that the attributes are complete and distinctive. Then, the attribute fields are structured and combined through the encoding engine, and a globally unique traceability identification code is generated using the snowflake algorithm or UUID algorithm to ensure that there will be no duplication even under high concurrency conditions. Next, the system converts the traceability identification code into a graphic code through the QR code generation module, and combines it with the RFID writing module to generate an electronic tag to achieve a one-to-one correspondence between digital information and physical instruments. Finally, the identification code is attached to the body of the surgical instrument by means of laser etching, thermal printing or chip embedding.

[0024] It should be noted that, in this application, the configuration attributes of surgical instruments refer to a set of static information on the structural characteristics, functional uses and management ownership of surgical instruments, including instrument number, name, type, material, size specifications, applicable departments, frequency of use, cleaning and sterilization requirements, etc.; the traceability identification code refers to a coding identification used to uniquely identify surgical instruments and realize full-process tracking.

[0025] In this embodiment, the traceability identification code is associated with the instrument status data of the surgical instrument in different scenarios in real time to obtain the operation association information. The following steps can be used: Determine the scene type label through the real-time operation scene of the surgical instrument; Collect instrument status data of surgical instruments in different scenarios; The scene type tag is bound to the device status data to obtain operation association information.

[0026] In specific implementation, first, an identification device for automatic scene recognition is deployed in each instrument operation scene (such as instrument cleaning areas, disinfection areas, operating rooms, and temporary storage points). Fixed RFID readers are installed in cleaning areas and operating rooms to read the RFID chip information on the instruments and automatically label them with labels such as "cleaning area" and "operating room." Alternatively, a QR code scanner installed at the entrance of the venue scans the instrument's QR code to enter the system and automatically associate it with the current scene. For smart venues that support positioning, a Wi-Fi / AP positioning system can be used to automatically infer the scene type tag of the current scene by reading the coordinate range of the device's location. Next, the controller on the cleaning and disinfection equipment (such as a PLC or industrial control contact) collects cleaning time, temperature, completion status, and other information. A barcode scanner is used to collect personnel scanned code information at the operation node, and the instrument usage time and operator ID are recorded in conjunction with the console system. The weighing module or sensor at the packaging workstation is then used to detect whether the packaging is complete. The collected data is aggregated by edge devices and sent to a central database in a standard format. The central database is then read to obtain the instrument status data in different scenarios. Finally, an operation record structure is constructed, with fields including: traceability identification code, scenario type label, status data, timestamp, operator number, and device number. This includes: every time a device is identified as entering a new scenario, the device status data corresponding to the scenario is immediately obtained; the scenario type label and the device status data are concatenated to generate an operation event record; the operation event record is written into the operation chain database (such as MongoDB or PostgreSQL time series table) in a JSON structure; and operation association information is then constructed using the traceability identification code as an index.

[0027] It should be noted that in this application, the real-time operation scenario represents the specific processing environment in which the surgical instrument is currently located; the scenario type label refers to the semantic label used to identify the business node in which the surgical instrument is currently located, where the business nodes include cleaning, disinfection, surgery, and recycling; the instrument status data refers to the operating status of the surgical instrument in a specific scenario; the operation association information refers to the structured process information formed by binding the scenario type label of the instrument in different operation scenarios with the corresponding status data, with the traceability identification code as the main index.

[0028] In step S2, the dynamic flow path of the surgical instrument is obtained from the instrument supply terminal, and the handover constraint label of the surgical instrument during the handover process is determined based on the dynamic flow path and the operation association information, and then the comparison interaction sequence of the surgical instrument in the inventory link is determined based on the handover constraint label.

[0029] Specifically, obtaining the dynamic flow path of surgical instruments from instrument supply terminals can be achieved through the following methods: First, identification devices, including RFID readers, QR code scanners, and IoT edge gateways, are deployed at instrument supply terminals (such as cleaning centers, sterilization areas, surgical preparation areas, operating rooms, and recycling points) to detect the traceability identification codes attached to the instruments. As the instrument passes through each node, the identification devices automatically capture the instrument ID, current location, timestamp, and current operation type, and upload this data in real time to a central management platform. By comparing the time series with the node sequence, the entire process of the instrument from the supply center to use and then to recycling can be automatically restored. To enhance accuracy, auxiliary positioning technologies such as GPS and UWB can also be introduced to ensure the real-time and accuracy of node switching. Finally, all collected data is concatenated in chronological order to generate the dynamic flow path of the instrument.

[0030] It should be noted that in this application, the instrument supply terminal refers to the management node where surgical instruments are received, distributed, cleaned, and disinfected in the supply chain; the dynamic flow path refers to the time sequence trajectory of the real-time movement and operation of surgical instruments in each link of the supply chain.

[0031] Preferably, in this embodiment, the handover constraint label of the surgical instrument during the handover process is determined according to the dynamic flow path and the operation association information, with reference to Figure 2 As shown in FIG, this figure is a schematic diagram of a process for determining a handover constraint tag in some embodiments of the present application. In this embodiment, determining a handover constraint tag can be implemented using the following steps: In step S21, the key path features of the surgical instrument during the handover process are extracted from the dynamic flow path; In step S22, the constraint logic corresponding to the state of the surgical instrument is determined according to the operation association information; In step S23, the constraint logic is converted into a tag determination condition that can be dynamically loaded; In step S24, the handover constraint label of the surgical instrument during the handover process is determined by the key path feature and the label determination condition.

[0032] In its implementation, the system first queries instrument flow records using a time series database to identify all time periods where "handover" operations occurred. The dwell time and flow intervals at handover points are analyzed, and the time difference and sequential relationship between nodes are calculated. The IDs of the personnel involved in the handover and the equipment information are extracted from the operation-related information to generate the critical path characteristics of the surgical instrument handover process. Next, a business logic rule base is defined using a rule engine (such as Drools). The rules in the logic rule base include conditional judgments on the instrument status field. Anomaly patterns are analyzed based on historical handover data, and rule weights and priorities are dynamically adjusted. The operation-related information is input into the logic rule base through an interface for real-time logical judgment, resulting in the constraint logic corresponding to the surgical instrument status. The logic rule base is then exported as a conditional expression template in JSON format. During system runtime, the conditional template is dynamically loaded and variables are populated based on the current instrument status. The conditional expression is used to evaluate the input parameters, outputting a Boolean result indicating whether the handover constraints are met. This Boolean result is then used as a dynamically loadable label judgment condition. Finally, the Boolean results of the critical path characteristics and label judgment conditions are used as input. A predefined label rule library is used to match multiple condition combinations and generate corresponding handover constraint labels, such as "compliant handover," "delayed handover," and "inadequate authority." If multiple labels meet the conditions, the final label is selected based on priority, resulting in the handover constraint labels for the surgical instrument during the handover process.

[0033] It should be noted that in this application, the critical path feature represents the feature set of key nodes, time intervals, and operation sequences in the handover process of surgical instruments; the constraint logic represents the rule conditions of surgical instruments in the handover operation; the label judgment condition represents the dynamic condition script that can be executed by surgical instruments in the handover link; the handover constraint label represents the label information that manages the operation restrictions and compliance requirements of surgical instruments in the handover link.

[0034] In this embodiment, determining the comparison interaction sequence of surgical instruments in the inventory phase according to the handover constraint tags can be achieved by using the following steps: parsing the ownership characteristic information of the surgical instrument in the inventory process according to the digital signature data in the handover constraint tag; Determine the counting rule chain for surgical instruments in the counting process; The comparison interaction sequence of surgical instruments in the inventory link is determined through the ownership feature information and the inventory rule chain.

[0035] In its implementation, digital signature verification technology is first used to decrypt and verify the digital signature in the handover constraint tag using a public key infrastructure (PKI) to ensure the tag's legitimacy. The encoded ownership information, i.e., the ownership characteristics of the surgical instrument during the inventory phase, such as the instrument's ownership unit, current responsible individual, authority level, and specific restrictions, is extracted from the digital signature. This parsing process is implemented using a dedicated decryption module and data parsing service, ensuring information security and integrity. Then, based on this ownership information, a pre-set inventory rule library is invoked. This pre-set inventory rule library contains standard inventory processes and corresponding rule chains for various scenarios. The rule chain logically defines the inventory steps, including identity verification, instrument status confirmation, quantity verification, and anomaly annotation. This results in the inventory rule chain for the surgical instrument during the inventory phase. Finally, the ownership information and the inventory rule chain are combined to automatically match and generate a specific inventory operation sequence that matches the instrument's characteristics. This specific inventory operation sequence serves as the comparison interaction sequence for the surgical instrument during the inventory phase. This comparison interaction sequence is displayed on the inventory personnel's terminal as a process script or operation instruction.

[0036] It should be noted that in this application, digital signature data represents encrypted information used to verify the authenticity and integrity of the handover constraint label; ownership characteristic information refers to the core attributes of the surgical instrument's ownership, responsible subject and operating authority in the inventory link; the inventory rule chain refers to the inventory operation rules and processes arranged in a logical order; the comparison interaction sequence refers to the specific operation steps and interaction sequence in the inventory link.

[0037] In step S3, the management evaluation log of the instrument inventory operator is obtained, and the distribution verification cycle of surgical instruments between the supply center and the operating room is determined based on the management evaluation log. The disposal authority level of the surgical instruments is then synchronously verified by the distribution verification cycle to generate collaborative traceability indicators for surgical instruments in the verification link.

[0038] In specific implementation, obtaining the management evaluation log of the equipment inventory operator can be achieved in the following way: by integrating an identity authentication module into the mobile terminal or workstation used by the inventory operator to ensure that each inventory operation is performed by a legitimate user, and to record the operation behavior data in real time, including operation time, type and quantity of inventory equipment, exception handling records, etc. Subsequently, the system automatically uploads this operation data to the centralized log management server, and combines the management evaluation model to analyze the compliance, efficiency, accuracy and other indicators of the operation to form a management evaluation log. This management evaluation log not only contains basic operation data, but also integrates scoring results, risk warnings and historical performance comparison information.

[0039] It should be noted that, in this application, the management evaluation log refers to a structured data set that records the operator's work performance and compliance assessment results.

[0040] Preferably, in this embodiment, the distribution verification cycle of surgical instruments between the supply center and the operating room is determined according to the management evaluation log, with reference to Figure 3 As shown in FIG, this figure is a flow chart of determining the allocation verification period in some embodiments of the present application. In this embodiment, determining the allocation verification period can be implemented by the following steps: In step S31, the hierarchical distribution index of surgical instruments between the supply center and the operating room is extracted from the management evaluation log; In step S32, the event allocation density of the surgical instrument in different allocation states is determined according to the hierarchical allocation index; In step S33, the allocation verification rules for distributing surgical instruments between the supply center and the operating room are obtained; In step S34, the allocation verification period of the surgical instruments between the supply center and the operating room is determined according to the event allocation density and the allocation verification rule.

[0041] In its implementation, the log management module first screens and analyzes stored management evaluation logs. Using data preprocessing techniques, such as cleaning invalid data and normalizing evaluation scores, key risk characteristics are extracted, including personnel compliance rate, abnormal event frequency, operational error rate, and instrument type. A hierarchical analysis approach is then used to categorize surgical instruments and their associated responsible personnel into high, medium, and low risk levels, generating a tiered allocation indicator. Next, the system collects real-time statistics on the number of allocation events between the supply center and the operating room from the supply chain operation logs, and calculates the event allocation density based on a time window. Time series analysis techniques are used to monitor the dynamic changes in allocation frequency, identifying high-frequency operation periods and abnormal fluctuations. The system then integrates a built-in allocation verification rule library based on industry standards and management requirements. The rules in this library detail the verification frequency, verification methods, and exception handling procedures for different risk levels and operational states. The rule management module dynamically maintains and updates the verification rules, incorporating the latest policies and historical feedback. These updated results serve as the allocation verification rules for surgical instruments between the supply center and the operating room. Finally, the event allocation density and allocation verification rules can be input through the rule engine to automatically calculate a reasonable allocation verification cycle. If the event density is high and the risk level is high, the system automatically shortens the verification cycle and increases the frequency of supervision; if the density is low and the risk is low, the cycle is appropriately extended to save resources.

[0042] It should be noted that in this application, the hierarchical allocation index refers to the allocation risk index divided for different surgical instrument categories or responsibility levels; the event allocation density refers to the frequency of allocation operations of surgical instruments between the supply center and the operating room per unit time; the allocation verification rule refers to the verification requirements and frequency standards to be performed under different allocation states; the allocation verification cycle refers to the time interval for verification and confirmation of surgical instruments between the supply center and the operating room.

[0043] In this embodiment, the allocation verification cycle is used to synchronously verify the disposal authority level of the surgical instrument, and the generation of the collaborative traceability index of the surgical instrument in the verification process can be achieved by the following steps: Obtain the authority level for handling surgical instruments; Determining a collaborative event flow of the surgical instrument during a disposal operation according to the disposal authority hierarchy; The allocation verification cycle is mapped to the collaborative event flow to obtain collaborative traceability indicators of surgical instruments in the verification link.

[0044] In its implementation, the database interface first calls the permission query API to retrieve the current handling permission information corresponding to the surgical instrument based on its unique identifier. This information includes the operator's identity, permission level, department affiliation, and executable operation types. The current handling permission information corresponding to the surgical instrument is stratified using a permission model to obtain the handling permission hierarchy. This permission model utilizes role-based access control (RBAC) combined with fine-grained operation authorization policies to ensure clear and dynamic permission hierarchy. Then, within the business process, the handling permission hierarchy is read and an operation sequence diagram is automatically generated based on the permission level and scope of responsibility. A process engine such as Camunda can be used to construct an event flow graph. Each event node represents an operation task and is bound to an execution role and conditional trigger. The collaborative event flow is dynamically generated through a process node definition, node condition setting, node execution monitoring, and event flow status tracking. Finally, the allocation verification period is injected as a time trigger condition into each key node in the collaborative event flow, requiring that an operation event must complete within the allocation verification period. The time trigger is managed using the Quartz timer engine. If a task is not completed within the period, it is automatically marked as deferred, triggering the permission re-verification logic. This process will recheck whether the current operator has the current node operation authority and compare whether the authority matches the status. The verification results are recorded in the traceability log. During each allocation verification cycle, the execution log of the collaborative event flow is collected in real time, including task trigger time, execution role, completion status, and permission verification results as input data. The event processing engine is used to perform multi-dimensional aggregation analysis on dimensions such as task completion rate, timeliness, permission consistency, and role coverage. Abnormal behaviors are labeled and classified, and quantifiable collaborative traceability indicators are generated based on the analysis results. I will not go into details here.

[0045] It should be noted that in this application, the disposal authority level refers to the operating scope of operators at different levels over surgical instruments in each processing link; the collaborative event flow refers to the process status of multi-party interaction in the verification and disposal links of surgical instruments; the collaborative traceability indicator refers to the quantitative identification of the traceability collaborative effect of surgical instruments in the verification link.

[0046] In step S4, directional closed-loop management is performed on the surgical instrument according to the comparison interaction sequence and the collaborative traceability index.

[0047] In this embodiment, the directional closed-loop management of surgical instruments based on the comparison interaction sequence and the collaborative traceability indicator can be achieved by the following steps: Determining a conflict detection mark of the surgical instrument in the management link according to the comparison interaction sequence; Determine a directional closed-loop strategy for surgical instruments in the management process based on the collaborative traceability indicators; Constructing a dynamic event response chain in the surgical instrument management process based on the conflict detection mark and the directional closed-loop strategy; A directional management topology for the entire life cycle of surgical instruments is generated through the dynamic event response chain.

[0048] In specific implementation, the execution time, operator ID, and verification results of each inventory action in the interaction sequence are analyzed and compared. A rule engine is then used to detect the following conflict scenarios: inventory results inconsistent with device configurations; duplicate registration of the same device by multiple roles; missing or timed inventory records. When any rule is triggered, a conflict detection flag is assigned to the device and written to the exception log database. The conflict detection flag format includes the conflict type, discovery node, resolution status, and recommended resolver. Next, closed-loop response rules are configured using collaborative traceability metrics such as operational compliance rate, task delay rate, and authority deviation rate. These closed-loop response rules include: if the timeout rate is high, the device's priority in the handover process is increased and a mandatory review is mandatory; if the authority deviation rate is high, joint verification by multiple roles is required; and if there is a disagreement about the responsible party, the process is transferred to the manual intervention pool. Rules in the policy engine are stored as rule-action pairs. After matching conflict flags, a response action instruction set is automatically generated and injected into the management process as a targeted closed-loop policy. Then, a dynamic event response chain can be dynamically generated through a process modeling component (such as a BPMN engine), creating response nodes based on a directed closed-loop strategy. These response nodes include "information locking," "authority collection," "device isolation," and "cross-verification." The dynamic event response chain is stored in a directed graph structure, with each node setting the executor, trigger conditions, and completion criteria. Finally, the event nodes and their dependencies are extracted from the dynamic event response chain. Combined with information such as the flow path, authority hierarchy, and execution log bound to the device traceability identification code, a topology diagram is constructed and used as the directed management topology. The topology diagram is stored and visualized using a graph database (such as Neo4j). Nodes in the diagram represent device state transitions or operational events, and edges represent process relationships between events. Users can use the visualization platform to view the full path operational information of any device, from configuration to inventory, handover, and disposal.

[0049] It should be noted that, in this application, conflict detection mark refers to the mark used to identify operational conflicts, ownership conflicts or data anomalies discovered during the management process; directional closed-loop strategy refers to personalized management rules dynamically configured for risky devices; dynamic event response chain refers to the event processing process sequence generated after conflicts and anomalies are triggered; directional management topology refers to a visual management network diagram constructed with the device as the core node, centering on its operation flow, response chain and status changes in each link.

[0050] It can be seen that in this application, the configuration attributes, usage status, flow path and operation behavior of surgical instruments can be perceived in real time and multi-dimensional correlation analysis can be performed; among them, based on the configuration attributes of surgical instruments, traceability identification codes are generated and the instrument status data is associated in real time, so as to realize the accurate identification of the global status information of surgical instruments and structured perception of operation behaviors, thereby improving the integrity and accuracy of traceability data; by extracting dynamic flow paths and combining operation-related information to generate handover constraint labels and comparison interaction sequences, the path status of surgical instruments in the handover and inventory links can be refined, and the perceptibility and traceability of key nodes can be enhanced; by analyzing management evaluation logs to determine the allocation verification cycle and synchronously verify the authority level, the coupled perception of personnel behavior and instrument status can be realized, and the consistency and timeliness of authority changes and traceability verification under multi-source information can be improved; by comparing interaction sequences and collaborative traceability indicators to build a dynamic response chain, the dynamic perception and strategy-driven of global status information in the multi-link closed-loop management of surgical instruments can be realized, significantly improving the traceability accuracy and control capabilities in the management process.
