Description

Technical Field

[0001] The present invention relates to the technical field of surgical instrument inventory recovery, and in particular to a surgical instrument identification device, recovery method and system. Background Art

[0002] Surgical instruments are the largest mobile fixed assets in hospitals, with a wide variety and huge quantity. Usually, a single large medical center in Europe and the United States has 20,000-40,000 surgical instruments, and a single tertiary hospital in China has more than 100,000-300,000 surgical instruments. Fixed asset inventory verification and daily status monitoring are not supported by technical means, fixed asset accounts do not match the actual assets, and the scrapping supervision process is not compliant. These problems are relatively common and need to be solved urgently. The national legislation on medical device UDI supervision clearly states that the traceability of surgical instrument UDI circulation within the hospital is an integral part of the full life cycle chain of medical device supervision.

[0003] On the one hand, according to the "Operating Room Nursing Practice Guidelines", the inventory of reusable surgical instruments used in surgery must follow the principle of two people counting four times: the hand-washing nurse and the circulating nurse count before the start of the operation, before closing the body cavity, after closing the body cavity, and after suturing the skin. With the widespread application of minimally invasive technology, surgery is moving towards a shorter time, less bleeding, and faster recovery. Taking gastrectomy as an example, the traditional surgical plan takes at least 30 minutes, while the continuous suture technology can reduce the abdominal closure time to within 10 minutes. The time reduction is a huge challenge for our repeated counting of reusable instruments. How to quickly and accurately count reusable surgical instruments to prevent surgical instruments from being left in the patient's body, avoid secondary harm to the patient, and improve the efficiency of the operating room, is urgently waiting for us to provide a solution.

[0004] Due to the large variety and complex structure of reusable surgical instruments, it is impossible to install RFID chips on all of them. Only some surgical instruments can be installed. Some instruments are placed in the same basket and RFID chips are arranged on the basket. How to solve the problem of rapid and accurate identification of instruments with and without RFID chips at the same time requires the integration of RFID automatic identification technology, automatic weighing technology and intelligent control system to achieve intelligent management.

[0005] On the other hand, surgical instruments often need to be counted repeatedly during surgery, which brings tedious work to hospital staff. When the number of instruments is too large, the risk of incorrect counting by manual counting will be more prominent. The daily trajectory of surgical instruments is complex: from the operating room to the supply room, dispersed-centralized-dispersed, and a large number of external instruments are intersected, with a wide range of contact: the contact range of hospital staff is surgeons-instrument nurses-disinfection supply-internal transportation, and it is often difficult to control the quality of disinfection supply. Surgical instruments coexist in multiple states, and a large number of broken and rusted surgical instruments have accumulated over the years. Rust contamination easily occurs, causing instrument corrosion, incision infection, and explosive inflammatory reactions; high sterilization cost / low instrument utility: a large number of functionally failed instruments cannot be maintained and replaced, and are repeatedly configured in the surgical instrument package to meet surgical needs, resulting in a huge number of instruments in the instrument package and high sterilization costs.

[0006] In order to solve the above difficulties, it is urgent to achieve accurate traceability of each surgical instrument to meet the needs of in-hospital management. Summary of the invention

[0055] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0056] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0057] Example 1

[0058] like Figure 1 The figure shows a schematic diagram of the structure of a surgical instrument identification device, which is mainly used for counting and recovering surgical instruments. The surgical instrument identification device includes a bracket, a work surface arranged on the bracket, and a control module. The work surface includes a sensing identification area and a weight identification area, and a shielding edge is arranged at the edge of the work surface. In the sensing identification area and the weight identification area, a sensing identification module and a weight identification module that are communicatively connected to the control module are correspondingly arranged. As an option, the device can also be provided with a roller mechanism for moving and positioning the bracket to facilitate the movement and braking of the device.

[0059] The induction recognition module is used to recognize the electronic tag of the surgical instrument to be recycled to obtain the instrument information of the surgical instrument to be recycled. The induction recognition module may not be limited to an RFID recognition module.

[0060] The weight identification module is used to obtain the weight information of the surgical instrument to be recovered, and to obtain the instrument information of the surgical instrument to be recovered based on the weight information.

[0061] The control module is used to compare the instrument information with the recycling list, or send it to a management platform (located on a computer terminal or mobile terminal, etc.) that is connected to it, and then compare it with the recycling list in the platform to complete the inventory and recycling of the surgical instruments to be recycled. Optionally, the control module compares the weight information of the surgical instruments to be recycled with the pre-stored weight information. If the comparison is consistent, the inventory and recycling of the surgical instruments to be recycled is completed.

[0062] In this embodiment, the surgical instrument identification device is equipped with both a sensing identification area and a weight identification area. By using sensing identification and weight identification in conjunction with each other, both instruments with and without electronic tags can be quickly and accurately identified at the same time.

[0063] For example, Figure 1The weight identification area of ​​the work surface shown can be set to occupy 1 / 4 of the work surface. In this embodiment, the sensing identification area is larger than the weight identification area, so that the sensing identification area can simultaneously identify the electronic tags of multiple surgical instruments to be recycled. The weight identification area is mainly used to identify surgical instruments to be recycled that do not have electronic tags. Generally, such instruments are relatively small. Multiple instruments are stored in a storage frame or storage box for weighing, so the area can be reduced.

[0064] certainly, Figure 1 This is only an optional embodiment provided by the present invention. The present invention does not specifically limit the size, shape, etc. of the area division corresponding to the sensing identification area and the weight identification area.

[0065] As an option, the device may also be provided with a switch module for user input instructions, including but not limited to a foot switch for manually starting the device, and the foot switch is arranged at the lower half of the bracket or near the wheel, and a weighing switch for manually starting the weight identification module. User input instructions include but are not limited to power-on instructions, power-off instructions, calibration instructions, peeling instructions, weighing instructions, induction identification instructions, etc. In other words, the control module calibrates the weight identification module to a preset weight according to the calibration instructions input by the user, and performs a peeling operation on the weight identification module according to the peeling instructions input by the user.

[0066] Moreover, the surgical instrument identification device also includes a voice broadcast module electrically connected to the control module, which is used to convert the instrument information into voice information according to the broadcast instruction issued by the control module to broadcast the instrument information such as the real-time weight. In other words, after each weighing, the instrument table automatically broadcasts the current weight. Optionally, the voice broadcast function can also be set to be manually turned off (such as setting a key switch) or automatically turned off (such as setting a specific trigger condition, and automatically turning off when the corresponding trigger condition is reached, etc.).

[0067] Exemplarily, the weighing instruction includes a zeroing instruction. Place the surgical instrument identification device on a flat and hard place, press the TARE button, and then the LED display will be fully displayed and zero will be grasped. After zeroing is completed, 0g will be displayed. Then, the items are placed on the sensing identification area and weight identification area of ​​the work surface in turn. After stabilization, the weight value of the items is broadcast by voice, and the instrument information such as item ID and weight information is transmitted to the management platform or control module. By comparing with the recycling list and other related processing, it is determined whether the surgical instruments to be recycled are recycled. The device is equipped with an overweight alarm function. When the weight exceeds the preset weight, such as 10kg, "Err" can be displayed through LED, LCD, OLED and other display methods, and the weight identification module or the entire device will be automatically turned off after a preset time (such as 5s). As an option, the TARE button can be set to be used for multiple purposes, including but not limited to pressing the TARE button to turn on the machine in the off state; pressing this button to reset the machine in the on state; pressing the TARE button for more than 2 seconds in the on state to turn off the machine, etc.

[0068] About calibration: After pressing the TARE button to turn on the device, press and hold the TARE and OK buttons at the same time to enter the calibration function, or after setting the corresponding parameters through the applet, directly enter the calibration mode after connecting to the device. Then, press the OK button to display 5000, put a 5Kg weight to perform a 5Kg calibration; after the weight stabilizes, it automatically jumps to display 10000, put a 10Kg weight to perform a 10Kg calibration, and when the weight stabilizes, the 10Kg calibration is completed, and the display automatically jumps to pass to complete the calibration.

[0069] About tare: Place the item on the device, press and hold the TARE button for more than 2 seconds to enter the tare function, or set the corresponding parameters through the mini program, connect to the device and enter the tare mode. The surgical instrument identification device will save the tare weight or upload it to the management platform.

[0070] Optionally, the surgical instrument identification device may also have a built-in Bluetooth module that is connected to the smart terminal, which can transmit the instrument information and other relevant information to the smart phone applet in real time and display it for the user to view or operate. The surgical instrument identification device may also have a built-in WiFi module to enable it to have networking capabilities, and can transmit the instrument information and other relevant information to the management platform in real time and / or receive commands issued by the management platform, etc. That is to say, this device can easily and quickly identify the identity of items through RFID electronic tags, weigh them in real time, and transmit the item ID and weight-related data to the management platform through the built-in RFID identification module and weight identification module. At the same time, the management platform can also monitor the degree of wear and tear and / or the service life of the corresponding surgical instrument based on the weight information received from the surgical instrument identification device.

[0071] like Figure 2As shown, in some embodiments, the surgical instrument identification device further includes a power module 40 for supplying power to the control module 10, the induction identification module 20, and the weight identification module 30. Alternatively, the power module 40 may be a rechargeable lithium polymer battery. Specifically, the device is equipped with a built-in rechargeable lithium polymer battery with a TYPE C charging interface, which can be charged through an external power adapter.

[0072] Based on the above embodiments, the surgical instrument identification device is also provided with a power saving mode, that is, if the device does not detect relevant operations within a preset time (such as 1 minute or 2 minutes), it will automatically shut down. The device is also provided with a firmware upgrade module, which can be connected locally or remotely for firmware upgrade. In this embodiment, the device can achieve accurate traceability of each surgical instrument, thereby accurately managing each surgical instrument and ensuring surgical needs.

[0073] In some embodiments of the surgical instrument identification device, the surgical instrument identification device of this embodiment is also configured with at least one storage frame with an electronic tag, and the storage basket is used to store surgical instruments to be recycled that cannot read the electronic tag (do not have an electronic tag). The weight identification module is used to weigh the storage basket to obtain the weight information of the surgical instruments to be recycled in the frame and transmit it to the control module, and the induction identification module is used to identify the electronic tag of the storage basket and transmit it to the control module. The control module compares the instrument information of the surgical instruments to be recycled obtained based on the electronic tag of the storage basket and the weight information of the surgical instruments to be recycled in the frame with the recycling list, or sends it to the terminal management platform connected to the communication, and compares it with the recycling list in the platform, so as to complete the inventory and recycling of the surgical instruments to be recycled.

[0074] This embodiment uses inductive identification and weight identification in combination, so that both devices with and without electronic tags can be quickly and accurately identified at the same time.

[0075] Alternatively, the storage basket is provided with a plurality of neatly arranged grids of the same or different sizes, and each grid can be used to store at least one or one type of surgical instrument to be recycled whose electronic tag cannot be read.

[0076] In this embodiment, the device can be used to count and recover each surgical instrument, thereby accurately tracing and managing each surgical instrument to ensure surgical needs.

[0077] Example 2

[0078] like Figure 3 As shown, the surgical instrument inventory recovery method of this embodiment includes the following steps:

[0079] S10: Determine whether the electronic tag of the surgical instrument to be recycled can be read. If yes, execute step S11; if no, execute step S12.

[0080] It should be noted that the electronic tag is preferably an RFID identification tag. Some surgical instruments have built-in RFID identification chips. By placing them on the sensing and identification area of ​​the surgical instrument identification device in the above embodiment, the electronic tag of the surgical instrument to be recycled can be obtained. Of course, they can be read one by one or in batches, that is, the surgical instruments to be recycled in the same batch are placed on the sensing and identification area for batch reading. Then, the surgical instruments to be recycled whose electronic tags cannot be read are screened and stored in the storage basket.

[0081] S11. Compare the electronic tag with the recycling list, and when the electronic tag is in the recycling list, it is determined that the recycling of the surgical instrument to be recycled is completed.

[0082] It should be noted that the recycling list refers to the recycling list of surgical instruments to be recycled that is cached in the control module, or the recycling list obtained by the surgical instrument identification device from the management platform, or the recycling list in the management platform. Each batch of surgical instruments to be recycled corresponds to a recycling list, and a batch can refer to all surgical instruments used in the same operation as a batch, etc. The recycling list contains the instrument information of all surgical instruments in the batch, including but not limited to the weight information of each instrument, the total weight information of all instruments, the quantity information of the same instruments, which instruments have no electronic tags, which instruments have electronic tags, and the electronic tag information of instruments with electronic tags.

[0083] S12. Obtain the current weight information of the surgical instrument to be recycled, and determine whether the error between the current weight information and the standard weight information in the recycling list is less than a preset threshold.

[0084] If so, it is determined that the recovery of the surgical instrument to be recovered is completed.

[0085] If not, an alarm will be issued.

[0086] It should be noted that the alarm reminder methods include but are not limited to voice alarm reminder, indicator light alarm reminder, alarm reminder using text or icons on a display screen, etc.

[0087] In some embodiments of the surgical instrument inventory recycling method, the standard weight information includes the standard total weight information of the surgical instruments whose electronic tags cannot be read in the recycling list, referring to Figure 4 , step S12 comprises:

[0088] S121. Weigh all surgical instruments to be recycled whose electronic tags cannot be read, and compare them with the standard total weight information in the recycling list to determine whether the error is less than a preset threshold.

[0089] The preset threshold is the weight value corresponding to the smallest surgical instrument among all surgical instruments without electronic tags in the recycling list. Of course, it can also be the maximum value in the set value range.

[0090] In some embodiments of the surgical instrument inventory recovery method, reference Figure 5 The standard weight information includes the standard sub-weight information of each surgical instrument whose electronic tag cannot be read in the recycling list. Step S12 includes:

[0091] S122. Weigh each surgical instrument to be recycled whose electronic tag cannot be read, and compare it with the standard sub-weight information in the recycling list to determine whether the error is less than a preset threshold.

[0092] Specifically, refer to Figure 6 In the step of determining whether the surgical instrument to be recovered is recovered in step S12, the following step is also included:

[0093] S123. When there are multiple surgical instruments to be recovered that have the same current weight information, the number of surgical instruments to be recovered that have the same current weight information is counted.

[0094] S124: Determine whether the number of surgical instruments to be recovered that have the same current weight information is greater than or equal to the number of surgical instruments that have the current weight information in the recovery list.

[0095] If so, it is determined that the recovery of the surgical instrument to be recovered is completed.

[0096] If not, an alarm will be issued.

[0097] In this embodiment, accurate traceability of each surgical instrument can be achieved, thereby accurately managing each surgical instrument and ensuring surgical needs.

[0098] Example 3

[0099] like Figure 7 As shown, the surgical instrument inventory recovery method of this embodiment includes the following steps:

[0100] S21, weigh the surgical instruments to be recycled and compare them with the standard weight information in the recycling list to determine whether the error is less than a preset threshold. If so, it is determined that the recycling of the surgical instruments to be recycled is completed. If not, execute step S22.

[0101] S22: Determine whether the electronic tag of the surgical instrument to be recycled can be read.

[0102] If yes, it is determined that the recovery of the surgical instrument to be recovered is completed.

[0103] If not, an alarm will be issued.

[0104] In the surgical instrument inventory recovery method of some embodiments, the standard weight information includes the standard total weight information of all surgical instruments in the recovery list, and step S21 includes:

[0105] All surgical instruments to be recycled in the same batch are weighed and compared with the standard total weight information to determine whether the error is less than the preset threshold.

[0106] Based on the above embodiments, Figure 8 As shown, the standard weight information includes the standard sub-weight information of each surgical instrument whose electronic tag cannot be read in the recycling list.

[0107] If not, in step S22, the step of giving an alarm reminder also includes:

[0108] When the electronic tag of the surgical instrument to be recycled cannot be read, each surgical instrument to be recycled whose electronic tag cannot be read will be weighed and compared with the standard sub-weight information in the recycling list to determine whether the error is less than the second preset threshold.

[0109] If so, it is determined that the recovery of the surgical instrument to be recovered is completed.

[0110] If not, an alarm will be issued.

[0111] Alternatively, the preset threshold in this embodiment may be the weight value corresponding to the surgical instrument with the smallest weight among all surgical instruments in the recycling list, or may be the maximum value in the set value range. Similarly, the second preset threshold is for a single surgical instrument to be recycled, so a deviation threshold or deviation value range may be set for the weight of each surgical instrument to be recycled in the recycling list. If it is a range, the second preset threshold is the maximum value of the deviation value range.

[0112] In this embodiment, accurate traceability of each surgical instrument can be achieved, thereby accurately managing each surgical instrument and ensuring surgical needs.

[0113] Example 4

[0114] refer to Fig. 9The surgical instrument management system of this embodiment includes a management platform and also includes the above-mentioned surgical instrument identification device. The management platform is communicatively connected to the surgical instrument identification device. The surgical instrument identification device transmits the obtained weight information of the surgical instrument to be recycled, the RFID electronic identity tag and other instrument information to the management platform, and the management platform compares the obtained instrument information with the instrument information in the recycling list pre-stored in the platform to complete the recycling inventory. As an option, the management platform can also serve as a host computer to issue relevant commands to the surgical instrument identification device. The management platform can also monitor the degree of loss and / or its service life of the corresponding surgical instrument based on the weight information received from the surgical instrument identification device.

[0115] In this embodiment, accurate traceability of each surgical instrument can be achieved, thereby accurately managing each surgical instrument and ensuring surgical needs.
