[0053] To make the objectives, technical solutions and advantages of the application clearer and more explicit, the application is further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application and do not limit the application.

[0054] The surgical instrument closed-loop monitoring method based on state transition described in the preferred embodiment of the application, as shown in Figure 1 The surgical instrument closed-loop monitoring method based on state transition includes the following steps:

[0055] Step S10, receiving the scheduling information sent by the preoperative scheduling system, generating an instrument list according to the scheduling information, extracting a plurality of target surgical instruments according to the instrument list, and updating the to-be-allocated state label of all the target surgical instruments to obtain the to-be-used state label corresponding to each target surgical instrument.

[0056] In the management of operating rooms in modern hospitals, the scheduling and management of instruments are very complex, and the state tracking of instruments is not accurate. There is no unified management platform that can accurately record the use state, cleaning condition, sterilization frequency and life cycle of each instrument, which makes it difficult to track and manage the quality and safety of instruments. Therefore, the application first records the state label of each target surgical instrument, and through the state label, the use state of each target surgical instrument can be easily known, and it can be judged whether the target surgical instrument is sterilized, whether it can be used, and whether its life cycle is limited, which significantly improves the management efficiency of the target surgical instrument.

[0057] Among them, each surgical instrument has its own current state label, and the selection standard of the surgical instrument is also based on the current state label, so that the whole cycle management of the surgical instrument can be realized through the state label, and the doctor can be helped to prepare suitable surgical instruments, avoiding the inconvenience caused by the need to replace the surgical instrument temporarily before the operation.

[0058] As Figure 2As shown, first, the scheduling information is received through the accessed preoperative scheduling system (for example, the accessed HIS, Hospital Information System), so as to arrange appropriate surgical instruments in advance for the operation; after determining the required surgical instruments according to the scheduling information, the standard template of the required instruments is inquired, and the state and availability of the current surgical instruments are checked (for example, whether the current surgical instruments have been sterilized); when it is judged that the work is completed and an executable result is obtained, a scheduling task list (including operation information, instrument list and target operating room) can be generated, and then an instruction is issued to the transfer trolley to perform preoperative preparation, thereby reducing the manual operation process and avoiding the errors caused by manual preparation.

[0059] Specifically, a connection with a preoperative scheduling system is established, and scheduling information sent by the preoperative scheduling system is received, and operation habit information of a corresponding doctor is extracted according to the scheduling information; an instrument list is generated according to the scheduling information and the operation habit information; all initial surgical instruments with an initial state tag are screened out according to the instrument list; a plurality of target surgical instruments are screened out from all the initial surgical instruments according to the operation habit information, and a to-be-allocated state tag of all the target surgical instruments is updated to a to-be-used state tag, and a first time stamp of the to-be-used state tag update of each target surgical instrument is recorded.

[0060] Wherein, the surgical instruments are placed in a fixed area before or after the operation, and this fixed area is a "state recognition point". In this sensing area, the sensor of each process node can perform state recognition, and the purpose of recognition of each process node is also different. For example, a pressure sensor or a weight sensor can be installed in the sensing area of the instrument tray on the operating table side, which is used to determine whether the surgical instrument has been used during the operation; an RFID (Radio Frequency Identification) or NFC (Near Field Communication) reading module and a weight sensor can be installed in the sensing area of the instrument recycling frame, which is used to realize unified delivery after the operation to identify the surgical instrument "used and to be cleaned"; a temperature, humidity and pressure sensor can be installed in the sensing area at the entrance of the cleaning tank in the sterilization room, which is used to determine whether the surgical instrument has entered the cleaning process; a secondary reading tag and a matching historical state chain can be installed in the sensing area of the preoperative preparation area (or the packaging area after cleaning of the surgical instrument), which is used to determine whether the surgical instrument has been sterilized and distributed.

[0061] Furthermore, based on the instrument list, all surgical instruments are screened out, wherein the surgical instruments represent all surgical instruments whose types are indicated in the instrument list; a connection is established with a position identification system to obtain positioning information sent by the position identification system, and all the surgical instruments are extracted based on the positioning information; the status tags of all the surgical instruments are identified, and all the initial surgical instruments whose status tags are initial status tags are screened out.

[0062] Among them, this process is the process of screening the surgical instruments needed for the current operation. After determining which surgical instruments are selected for the operation, these surgical instruments need to be located. Each surgical instrument (including instrument kits, instrument boxes, single instruments, etc.) is equipped with an RFID / NFC tag and combined with physical position sensors (such as UWB (Ultra-Wide Band) positioning technology, BLE (Bluetooth Low Energy)) for location tracking. If the surgical instrument does not follow the normal path (for example, it is left in the corner of the operating room after the operation), the system determines its current location through the RFID positioning, tag heartbeat package or the last recorded location of the surgical instrument. If the instrument has not passed any status node for a long time, it means that the process of the surgical instrument is abnormal and its status tag needs to be further set to an abnormal state. The scheduling platform will issue an "instrument left behind warning" to guide medical staff to manually return it to the recycling box or disinfection area and then re-identify it.

[0063] For example, when the operation is over, the nurse puts the used instruments into the instrument recycling box with RFID identification function, and then pushes the recycling box to the "post-operative logistics temporary storage area". The system automatically reads the instrument label and records the recycling time. The system marks the batch of instruments as "to be cleaned" and automatically pushes the "cleaning task" to the cleaning area personnel. If an instrument is not put into the recycling box (such as left in the operating room), the system will compare the instrument task list with the recycling record and prompt a "lost instrument warning".

[0064] like Figure 3 As shown in the figure, a closed-loop management system for surgical instrument status is displayed, which includes a three-layer horizontal structure: the upper layer is the instrument life cycle process, which includes "instrument preparation" → "surgical use" → "postoperative recycling" → "cleaning and disinfection" → "re-warehousing and distribution"; the middle layer is the perception-decision-feedback module, and each life cycle stage corresponds to a subsystem, such as "positioning module", "status identification module" and "abnormal warning module"; the bottom layer is the API connection between platforms with the HIS system, SPD system or logistics system.

[0065] Wherein, the state of each surgical instrument can be determined by the state sensor at each link, for example, in the instrument packaging link, the weight sensor set in the preoperative preparation area can be used for determination; and after the state tag of the instrument is recognized, the time point of each identification and the node of the identification link are recorded, so that the use state of the surgical instrument can be monitored throughout the process, and the surgical instrument can be managed. When the use of the surgical instrument at this link is completed, the state tag of the surgical instrument is further updated, for example, when the surgical instrument is in the state of the to-be-distributed state tag, after the packaging is completed, the weight sensor set in the preoperative preparation area identifies and records the identification event (including time and the node of the identification link), and then updates the state tag of the surgical instrument to the to-be-used state tag; through real-time sensing of the spatial position and life cycle state of the surgical instrument, the system forms the closed-loop tracking ability of "state-position-task", and the management efficiency of the surgical instrument is significantly improved.

[0066] Step S20, when all the target surgical instruments are packaged according to all the to-be-used state tags, and are transferred to the operating room by the transfer car, updating all the to-be-used state tags to obtain the corresponding in-use state tags.

[0067] Wherein, the process of packaging the target surgical instrument is the automatic scheduling process of the system: the system automatically generates the instrument flow path and operation task according to the task and state change, and the task list not only generates the instrument list, but also specifies which warehouse to dispatch the surgical instrument, arranges which automatic transfer car (or through manual picking) to dispatch the surgical instrument, the time and place of dispatch, and determines the identity of the doctor receiving the target surgical instrument after the dispatch arrives, so that the target surgical instrument is not sent to the wrong operating room, thereby avoiding medical affairs or reducing the efficiency of the operation.

[0068] Wherein, in order to improve the instrument transportation efficiency and reduce the manual operation intensity, the system supports the linkage of the intelligent transfer car with multi-layer structure and the layered checking receiving station, realizes the non-manual accurate distribution; the transfer car adopts a multi-layer material loading structure, each layer supports free partition configuration, the table top is equipped with a variable direction bevel gear, and the instrument package can be horizontally moved on the car; at the same time, the system combines the interoperative target information carried by the embedded RFID / NFC tag in the instrument package, after the vehicle arrives at the target operating room area, the corresponding instrument package is slid into the receiving station controlled by the sorting algorithm, the receiving station is provided with an automatic identification and checking module, which can read the received instrument package information in time, and performs interoperative checking and confirmation; after the distribution is successful, the system records the completion of the task, and drives the transfer car to the next operating room to perform the next task, until the whole task is closed.

[0069] Specifically, the surgical packs on the surgical trays in the operating room or all the target surgical instruments in the surgical packs are labeled and identified to obtain an identification result, wherein the surgical packs are obtained by packing all the target surgical instruments according to all the to-be-used state labels, and the surgical packs are moved to the surgical trays in the operating room by the transfer trolley; if the identification result indicates that the state label of the target surgical instrument is the to-be-used state label, the surgeon is guided to use the target surgical instrument, and the to-be-used state label of the target surgical instrument after use is updated to a use-in-progress state label, and a second time stamp of the use-in-progress state label update of each target surgical instrument is recorded; if the identification result indicates that the state label of the target surgical instrument is not the to-be-used state label, the corresponding target surgical instrument is marked as an abnormal state.

[0070] For example, when the target surgical instrument is packed into the instrument box, RFID scanning is performed to ensure that it is the correct target surgical instrument, and then the ownership of the surgical schedule ID is recorded, and the time stamp (first time stamp) of the target surgical instrument being packed is recorded, and the to-be-allocated state label of this target surgical instrument is updated to the to-be-used state label; further, when the target surgical instrument is placed on the intraoperative tray, or moved out of the instrument box, or scanned and identified during the operation, the target surgical instrument is identified by the weight sensor, and the use of the target surgical instrument is recorded by the surgical recording system, and the time stamp (second time stamp) of the use of the target surgical instrument is recorded, and the to-be-used state label of the target surgical instrument is updated to the use-in-progress state label.

[0071] In order to improve the instrument carrying efficiency and realize automatic fixed-point distribution in the operating room, the application designs a multi-layer structure transfer trolley with variable partition and intelligent sorting function, and a surgical receiving platform with automatic checking function, which together build a closed-loop transfer mechanism of "fixed-point identification → directional delivery → receiving and checking" in the instrument transfer process.

[0072] Among them, the transfer trolley adopts a multi-layer structure, each layer is an independent bearing unit, and has a large-capacity instrument package bearing capacity, each layer of the table surface is embedded with a variable-direction micro inclined wheel mechanism (similar to the roller in the logistics sorting system), which has the ability of directional movement and partition control of the instrument package; the system realizes dynamic matching based on the instrument package label and the operating room code based on the RFID / NFC label or chip signal embedded in each instrument package and the operating room binding signal in the hospital dispatching system, accurately identifies the target of the instrument package to be delivered when the vehicle drives to the designated operating room receiving station.

[0073] For example, if there is a hip replacement surgery scheduled at 8:00 am the next day, the surgeon is Dr. D, and the system automatically generates a recommended instrument list based on the procedure template and Dr. D's preferences for using surgical instruments the night before, then automatically selects available instruments based on the current inventory and instrument status (such as which ones have just been cleaned, which ones are still in the disinfection process), automatically generates a task list (for example, "pack instruments package B, C by 7:00 am → delivered by the transfer car to the 8th operating room"), and generates a receiving end reminder that the operating room nurse should scan the code to confirm receipt of the instrument package by 7:30 am; this entire process does not require manual assignment of tasks, but the system automatically assigns work lists based on the state flow.

[0074] Further, each operating room door is equipped with a corresponding receiving platform (also a multi-layer rack structure) with a read-write module and a position detection device. When the transfer car arrives at the operating room area, the system identifies the operating room through wireless signals, starts the transfer car sorting mechanism, and the instrument package is automatically moved out by the roller control unit at the corresponding level and slides into the receiving station, completing the precise delivery without human intervention. The receiving station automatically checks the identity of the instrument package through the label checking mechanism, and feeds back "delivery success" after verification. The transfer car continues to drive to the next room to perform the distribution task. If the instrument package chip does not match the target operating room, the system will prevent the distribution action and issue an abnormal prompt. At the same time, the system can automatically plan the path of multiple operating rooms based on the scheduling algorithm to maximize path efficiency and on-board loading capacity.

[0075] The multi-layer large-capacity intelligent sorting structure disclosed in the present application has a micro inclined wheel on each layer, which can accurately push the corresponding instrument package according to the scheduling task; it realizes "chip signal + operating room binding" based on dynamic matching of instrument package labels and operating room codes, which is not fixed binding. It ensures the accuracy of distribution and also ensures the flexibility of distribution; at the same time, the receiving station self-checking mechanism disclosed in the present application enables the receiving station to automatically identify and feedback, improving safety and task closure; and these whole-process dynamic executions, one-car multi-task, and automatic distribution in operating rooms, do not require manual sorting, reducing labor costs and avoiding human errors.

[0076] Further, when the state label of the surgical instrument is abnormal, for example, if a certain instrument does not enter the recycling or disinfection process after the surgery is completed, the system deduces its location through the last positioning information, marks it as "state abnormal" and gives a warning on the scheduling platform, and then guides medical personnel to perform on-site recovery and restore the normal flow chain by passing through the sensing area again; as shown in Figure 4 Each process (instrument packaging, instrument use, instrument cleaning, etc.) is controlled uniformly by the master control unit.

[0077] Among them, Figure 4The multiple modules content of state awareness and label positioning are displayed, including an RFID / NFC chip module (for identity recognition of target surgical instruments); state awareness sensors (such as pressure, humidity, and temperature, respectively installed at the entrances of surgical instruments at different process nodes); a BLE positioning communication module, a master control unit, and a power unit.

[0078] Step S30, receiving all the state information corresponding to the target surgical instruments sent by the multiple state sensors, and updating the state label corresponding to each of the target surgical instruments according to all the state information, until the state labels of all the target surgical instruments change to the to-be-assigned state label.

[0079] The surgical instruments need to be placed in a sensing area or a state recognition link node before or after surgery, for example, a pressure / weight sensor can be embedded in the "surgical table side instrument tray", and whether the surgical instrument is used during surgery is automatically recorded; an RFID / NFC reading module and a weight sensor can be arranged in the "instrument recycling frame", and after surgery, the system can identify the "used and to-be-cleaned" state of the surgical instrument; a temperature, humidity, and pressure sensing module can be matched at the "sterilization room cleaning tank entrance" to determine whether the surgical instrument enters the cleaning process; the label can be read again at the "repacking point (preoperative preparation area)" and matched with the historical state chain to determine whether the surgical instrument has been sterilized and assigned.

[0080] Specifically, the weight change of each of the target surgical instruments sent by the recycling frame sensor is received, and the in-use state label of each of the target surgical instruments is updated to the to-be-cleaned state label, and a third time stamp of the to-be-cleaned state label update of each of the target surgical instruments is recorded; the first sensing temperature of each of the target surgical instruments and the first duration of the first sensing temperature sent by the cleaning frame sensor are received, and the to-be-cleaned state label of each of the target surgical instruments is updated to the cleaned state label, and a fourth time stamp of the cleaned state label update of each of the target surgical instruments is recorded; the second sensing temperature of each of the target surgical instruments and the second duration of the second sensing temperature sent by the sterilization frame sensor are received, and the cleaned state label of each of the target surgical instruments is updated to the sterilized state label, and a fifth time stamp of the sterilized state label update of each of the target surgical instruments is recorded; all the target surgical instruments with the sterilized state label are sent to the packing workbench, and the sterilized state label of each of the target surgical instruments is updated to the to-be-assigned state label, and a sixth time stamp of the to-be-assigned state label update of each of the target surgical instruments is recorded.

[0081] For a surgical instrument, six status tags are updated during the surgical process again, and each time the status tag is updated, the corresponding timestamp is recorded, and the first status tag and the last updated status tag are both "to be allocated status tag", at this time the management closed loop of the surgical instrument is realized.

[0082] For example, for the target surgical instrument that has been used, the medical staff puts it, or the surgical instrument that is used in the operation but does not enter the disinfection process, into the recycling frame, triggers the weight change, and the weight sensor and the RFID reader identify the surgical instrument in the recycling frame, record the time when this process is completed (the third timestamp), and change the status tag of these surgical instruments to the cleaning status tag; further, the surgical instrument to be cleaned is put into the cleaning area, the temperature of the cleaning area can be set by the medical staff, when the surgical instrument passes through the cleaning port, it will be read by the RFID reader, at the same time, the temperature sensor or the humidity sensor of the cleaning area can judge whether the current cleaning environment meets the standard, then the status tag of the cleaned surgical instrument is updated to the cleaned status tag, and at the same time, the cleaning completion timestamp (the fourth timestamp) is recorded; after the surgical instrument is cleaned, it is sent to the disinfection area, and the high-temperature steam area is sensed, at the same time, the disinfection time is recorded, and then according to the environmental temperature and time of disinfection, it is judged whether the disinfection process meets the standard, then the status tag of the cleaned surgical instrument is updated to the disinfected status tag, and at the same time, the disinfection completion timestamp (the fifth timestamp) is recorded; finally, the disinfected surgical instrument is packaged again on the workbench, and is scanned and registered, and is read by the RFID or NFC reader, then the status tag of the surgical instrument is updated to the to-be-allocated tag, and at the same time, the timestamp (the sixth timestamp) of the completion of this process is recorded.

[0083] Among them, as shown in the figure, Figure 5 The perception layer is used to upload the status tag of the surgical instrument (including in use, to be cleaned, in disinfection, etc.), the middle is the monitoring system, including the status panel (for), the instrument list and the tag map, which is used to monitor the whole process of the surgical instrument; the right side is the module of feedback behavior, for example, when the abnormal alarm prompt "X number of surgical instruments are not recycled" appears, the automatic prompt of task adjustment will be prompted. Taking "instrument status" as the core driving to schedule, according to the real-time status and position information of each instrument, combining the hospital operation scheduling plan and physical scheduling resources, the whole process task list from preoperative preparation to postoperative recovery is automatically generated, according to the change of instrument status (such as "disinfection completed"→"to be packaged"), the system automatically triggers the subsequent task, through ensuring the cleaning and safe state of the instrument, reduces the medical accidents caused by uncleaned or unqualified state of the instrument, such as packaging, transportation and distribution instructions, realizes the intelligent closed loop of scheduling path and execution behavior.

[0084] If the instrument does not follow the normal path, i.e., does not follow the "to be used-used-in cleaning-washed-disinfected-to be distributed" process, the system determines its current location through its RFID positioning / label heartbeat packet / last recorded position and issues an "instrument left warning" to guide medical staff to manually return it to the recycling frame or disinfection area and then re-identify it.

[0085] Further, it is judged whether the weight change meets a preset weight range, and if not, the corresponding target surgical instrument is marked as an abnormal state; it is judged whether the first perceived temperature and the first duration both exceed a first preset standard, and if not, the corresponding target surgical instrument is marked as an abnormal state; it is judged whether the second perceived temperature and the second duration both exceed a second preset standard, and if not, the corresponding target surgical instrument is marked as an abnormal state; it is judged whether a time gap between the first timestamp, the second timestamp, the third timestamp, the fourth timestamp, the fifth timestamp and the sixth timestamp exceeds a preset time, and if so, the corresponding target surgical instrument is marked as an abnormal state; all historical second timestamps, all historical third timestamps, all historical fourth timestamps and all historical fifth timestamps of each target surgical instrument are obtained, and the number of uses of each target surgical instrument is obtained according to the number of all historical second timestamps, all historical third timestamps, all historical fourth timestamps and all historical fifth timestamps; if the number of uses of the target surgical instrument exceeds a preset number, the target surgical instrument is marked as a scrap instrument.

[0086] If the instrument does not follow the normal path, i.e., does not follow the "to be used-used-in cleaning-washed-disinfected-to be distributed" process, the system determines its current location through its RFID positioning / label heartbeat packet / last recorded position and issues an "instrument left warning" to guide medical staff to manually return it to the recycling frame or disinfection area and then re-identify it.

[0087] Further, for a surgical instrument used for too many times, the number of all second timestamps can be used to count the historical number of uses, so as to judge whether the surgical instrument has reached the edge of being scrapped; in addition to judging whether the surgical instrument needs to be eliminated according to the number of uses, the first second timestamp of the surgical instrument can also be used for judgment, and if a certain time is exceeded, the surgical instrument is eliminated, so as to avoid using unqualified surgical instruments in surgery, and further improve the safety of surgery.

[0088] Wherein, after the operation, the used instruments will be put into the recycling container with RFID or NFC reading function, the system automatically records the instrument recycling time and source operation room, updates the status to "cleaning", and generates the subsequent "cleaning task" to push to the cleaning area. If the instruments are not recycled on time, the system will compare the task list and recycling record, mark the abnormal state and warn on the platform.

[0089] Further, by monitoring the status tag of the surgical instruments throughout the process, and automatically generating instrument flow path and operation task according to the task and state change, the whole cycle of surgical instruments is monitored, the information island problem of surgical instrument management is solved, the information between the operating room and the supply room, the disinfection room is not smooth, which leads to low utilization rate of instruments and serious waste. And the whole process does not need manual allocation of tasks, but the system automatically distributes the work list according to the state flow, which significantly reduces the error and high labor burden caused by manual operation.

[0090] Further, if the target surgical instrument is in an abnormal state, the positioning information of the target surgical instrument sent by the position recognition system is received; the warning label is constructed according to the positioning information, and the medical staff is prompted to detect the target surgical instrument through the warning label.

[0091] As shown in Figure 6 By updating the status tag of the surgical instruments, the use state, cleaning condition, disinfection times and life cycle of each instrument can be accurately recorded, and the quality and safety of the instruments can be easily guaranteed. When the instrument is insufficient, the corresponding warning information can also be generated to prompt the medical staff to purchase in time, realizing intelligent feedback and intelligent management of surgical instrument management.

[0092] Further, the real-time state, position and use of the surgical instruments can be comprehensively viewed through the platform, the system automatically identifies the abnormal state and gives a warning, and intelligently optimizes the future instrument scheduling according to the actual use of the instruments, such as: instruments not recycled, instruments not disinfected, incomplete surgical instrument configuration, etc.

[0093] Further, based on big data analysis technology, the system can analyze the use frequency, life, maintenance needs, etc. of the instruments, and provide suggestions for equipment procurement, instrument maintenance cycle, inventory management, etc. Using machine learning algorithm, the system can optimize the allocation strategy of surgical instruments, reduce resource waste and improve the efficiency of instrument use.

[0094] The application accurately monitors the real-time position and real-time state of the target surgical instrument, combines surgical scheduling and dispatch resources, automatically adjusts the configuration and circulation of the instrument according to the surgical demand, generates a full-process task list, automatically records the use state and feedback information of each instrument, performs data analysis and prediction, realizes the closed loop of the dispatch path and the execution behavior, realizes the automation and precision of the instrument dispatch and use, breaks the information silos among the supply room, the operating room and the sterilization room, realizes the intelligent management of the whole process, reduces the errors of manual intervention, improves the resource utilization rate, reduces the waste of surgical instruments, and ensures the hygiene and safety of surgical instruments.
