Description

Technical Field

[0001] The present invention belongs to the technical field of medical instruments, and in particular relates to an intelligent surgical instrument table system. Background Art

[0002] In modern surgery, the preparation, inventory, and management of surgical instruments are crucial to ensuring smooth operations. Traditionally, surgical instrument management relies primarily on manual inventory and identification by instrument nurses. This method is not only time-consuming and labor-intensive, but also prone to human negligence, leading to instruments being missed or left inside the patient, increasing medical risks.

[0003] In recent years, technological advancements have led to the development of several intelligent surgical assistance systems. For example, some systems use barcodes or single RFID tags to identify instruments. However, these methods cannot provide real-time two-dimensional positioning of instruments on the operating table and lack the ability to locate instruments in three dimensions after they leave the table, limiting surgical efficiency and safety.

[0004] Therefore, there is an urgent need for an intelligent surgical instrument table system that can achieve accurate automatic identification, real-time positioning and intelligent inventory of instruments. Summary of the Invention

[0005] Based on this, in order to solve the above technical problems, an intelligent surgical instrument table system is provided.

[0006] The technical solution adopted in the present invention is as follows:

[0007] An intelligent surgical instrument table system, characterized by comprising:

[0008] a first unit, wherein the first unit is bound to the surgical instrument in a one-to-one correspondence, and the first unit stores instrument information of the surgical instrument;

[0009] A surgical instrument table, wherein a plurality of second units arranged in a horizontal array are embedded on the table surface of the surgical instrument table, and the second units are used to obtain instrument information through wireless communication with the first unit on the surgical instrument;

[0010] The control module is used to:

[0011] During the surgical preparation phase, the plurality of second units are used to obtain the instrument information of each surgical instrument on the surgical instrument table and generate a first surgical instrument list;

[0012] During the operation, the two-dimensional position of each surgical instrument on the surgical instrument table is monitored in real time based on the multiple second units, and the corresponding instrument information and two-dimensional position are synchronized to the display device in real time;

[0013] At the end of the operation, the plurality of second units are used to obtain the instrument information of each surgical instrument on the surgical instrument table, generate a second surgical instrument list, and compare the second surgical instrument list with the first surgical instrument list. If the comparison is inconsistent, an alarm is issued;

[0014] The display device is used to display the distribution of each surgical instrument to the wearer based on the instrument information and two-dimensional position synchronized in real time by the control module. When the surgical instrument leaves the surgical instrument table, the three-dimensional position of the surgical instrument is obtained in real time through the visual tracking module, and its distribution is updated in real time based on the three-dimensional position.

[0015] The present invention binds the first unit one-to-one to the surgical instrument, and the first unit stores the instrument information of the surgical instrument. A plurality of second units arranged in a horizontal array are embedded on the table of the surgical instrument table. The second unit can communicate wirelessly with the first unit. Based on this, the instrument information can be obtained through the second unit, the corresponding surgical instrument can be accurately and automatically identified, and the surgical instrument can be two-dimensionally positioned. At the same time, the surgical instrument can be dynamically tracked in three dimensions in combination with the visual tracking module, realizing the real-time positioning of the surgical instrument for the first time.

[0021] The following will illustrate the implementation of the present invention in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the present invention. The following corresponding embodiments are only for the purpose of clearly illustrating the invention content of the patent of this invention and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made based on the description of this embodiment. Any obvious changes or modifications that belong to the technical concept and invention content of the present invention are also within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides an intelligent surgical instrument table system, including a first unit 11, a surgical instrument table 12, a wireless communication module 13, an external command input device 14, a position indication device 15, a control module 16 and an augmented reality (AR) device 17.

[0023] The first unit 11 uses RFID chips, and there are multiple of them, which are bound one-to-one with (such as scalpels, hemostatic forceps, etc.) and are implanted in the corresponding surgical instruments. The first unit 11 stores the instrument information of the surgical instruments, and the instrument information includes unique identification information (such as ID), name and specification information, etc.

[0024] like Figure 2 As shown, the surface of the surgical instrument table 12 is embedded with multiple second units 12a arranged in a horizontal array. The second units 12a use NFC chips to form an NFC chip array in a grid shape. The NFC chip can obtain instrument information through near-field communication with the first unit 11 on the surgical instrument.

[0025] The NFC chip array adopts a modular design, and the number and layout of chips can be adjusted according to the size of the surgical instrument table.

[0026] Each NFC chip covers an area of ​​5cm×5cm, and the communication distance of the RFID chip is 0-5cm.

[0027] Based on the first unit 11 and the second unit 12a, the two-dimensional position of each surgical instrument on the surgical instrument table 12 can be monitored: the short-range characteristics of the NFC chip give it a natural spatial resolution capability. When a surgical instrument is close to an NFC chip, only the chip can read the instrument information. The physical position of the NFC chip on the surgical instrument table 12 can be used to map the two-dimensional position of the surgical instrument (the position on the surgical instrument table 12). If multiple adjacent NFC chips read the instrument information in the same NFC chip at the same time, the two-dimensional position of the surgical instrument can be determined by signal strength (RSS I) or phase difference algorithm (such as triangulation positioning).

[0028] It is understandable that the first unit 11 and the second unit 12a are not limited to using RFID chips and NFC chips, and the two can use other devices and communicate in a wireless manner.

[0029] The wireless communication module 13 is used to realize communication between the augmented reality device 17 and the control module 16. In this embodiment, a short-range wireless communication module, such as a UWB (Ultra Wi deband) module, is used to establish a low-latency connection with the augmented reality device 17, with a transmission rate of up to 10Mbps, and real-time update of data.

[0030] The external command input device 14 is used for the user to input external commands to specify a target surgical instrument, and sends the external commands to the control module 16. In this embodiment, the external command input device 14 is a voice input device.

[0031] The position indicating device 15 is used to indicate the position of the target surgical instrument on the surgical instrument table 12 to the user.

[0032] In this embodiment, the position indicating device 15 adopts a laser pen auxiliary positioning device, which includes a manipulator and a laser pen. The manipulator is set on the surgical instrument table 12, and the laser pen is fixed to the manipulator. Under the drive of the servo motor, the manipulator adjusts the position of the laser pen so that the laser spot (diameter is about 3 mm) generated by it can stay at the location of different surgical instruments on the surgical instrument table 12.

[0033] The control module 16 uses an embedded processor (such as an ARM Cortex-A series) and integrates a speech recognition algorithm and a machine learning model (such as a natural language processing (NLP) model). The control module 16 is used to:

[0034] 1. During the surgical preparation stage, the instrument information of each surgical instrument on the surgical instrument table 12 is obtained through the NFC chip array, and a first surgical instrument list is generated, thereby achieving accurate identification of the surgical instruments.

[0035] 2. During the operation, the NFC chip array is used to monitor the two-dimensional position of each surgical instrument on the surgical instrument table 12 in real time, and the corresponding instrument information and two-dimensional position are synchronized to the augmented reality device 17 in real time through the wireless communication module 13. The target surgical instrument can be determined according to external instructions, and the two-dimensional position of the target surgical instrument can be determined. The position indication device can be controlled to indicate the position according to the two-dimensional position of the target surgical instrument.

[0036] 3. At the end of the surgery, the NFC chip array acquires the instrument information of each surgical instrument on the surgical instrument table 12, generates a second surgical instrument list, and compares the second surgical instrument list with the first surgical instrument list. If the comparison is inconsistent, an alarm is issued. The alarm can be issued through sound, light, or a prompt box in the augmented reality interface. For example, the control module 16 sends an alarm signal to the augmented reality device 17 via the wireless communication module 13, causing the augmented reality device 17 to display a red prompt box in the augmented reality interface and triggering a buzzer on the surgical instrument table 12 to sound an alarm.

[0037] The augmented reality device 17 serves as a display device, and is used to display the distribution of each surgical instrument to the wearer in an augmented reality interface based on the instrument information and two-dimensional position synchronized in real time by the control module 16. When the surgical instrument leaves the surgical instrument table 12, the three-dimensional position of the surgical instrument is obtained in real time through the visual tracking module 18, and its distribution is updated in real time based on the three-dimensional position.

[0038] Among them, the visual tracking module 18 can adopt visual tracking algorithms such as target detection algorithms based on deep learning and SLAM algorithms.

[0039] In this embodiment, the augmented reality device 17 is integrated with a visual tracking module 18, which includes a high-resolution camera and a depth sensor, and can achieve target tracking and spatial positioning in a surgical environment with an accuracy of ±5mm, such as an Apple Vision Pro device.

[0040] Of course, in addition to the augmented reality device 17, a display screen can also be used as a display device, and the display device can be connected to the control module 16 by wire. In this embodiment, the wireless communication module 13 can be omitted.

[0041] The system of the embodiment of the present application can be applied to various surgical scenarios, such as joint replacement surgery, heart surgery, neurosurgery, etc. Taking joint replacement surgery as an example, the working principle of the system of the embodiment of the present application is as follows:

[0042] During the surgical preparation stage, the instrument nurse places 10 surgical instruments (such as retractors, oscillating saws, trial prostheses, etc.) implanted with RFID chips 11 on the surgical instrument table 12. The control module 16 reads the instrument information from the RFID chip 11 through the NFC chip array, completes the registration of the instrument and generates the first surgical instrument list.

[0043] During the operation, the control module 16 monitors the two-dimensional position of each surgical instrument on the surgical instrument table 12 in real time, and synchronizes the corresponding instrument information and two-dimensional position to the augmented reality device 17 in real time through the wireless communication module 13. The instrument nurse wearing the augmented reality device 17 can intuitively view the instrument distribution through the augmented reality interface (for example, in the augmented reality interface, a virtual label 3 is associated with each instrument 2. The virtual label 3 is generated based on the instrument information, and the shape of the virtual label 3 can be consistent with the shape of the instrument, see Figure 3 ), when the doctor requests a "bone knife", the instrument nurse takes the target surgical instrument from the surgical instrument table 12 according to the instrument distribution in the augmented reality interface and hands it to the doctor. When the instrument is picked up and leaves the table, the augmented reality device 17 takes over the positioning task, uses the visual tracking module for visual tracking, and updates the three-dimensional position of the instrument in real time and synchronizes it in the augmented reality interface, thereby realizing real-time positioning of the surgical instrument.

[0044] When the NFC chip array fails to read the instrument information of a surgical instrument, the control module 16 performs auxiliary identification through the camera of the visual tracking module 18 and records the abnormal situation for subsequent inspection.

[0045] For users who are not wearing the augmented reality device 17, external instructions are input through the external instruction input device 14 by voice input (such as "pass me the hemostat") to specify the target surgical instrument. The control module 16 parses the external instructions, determines the two-dimensional position of the target surgical instrument, and controls the position indication device 15 to indicate the position according to the two-dimensional position of the target surgical instrument, thereby providing an effective auxiliary positioning means and improving application flexibility.

[0046] In actual applications, different users may call the same surgical instrument differently (such as "hemostatic forceps" or "mosquito forceps"). The machine learning model learns the personalized names of surgical instruments by different users through machine learning algorithms, and can adapt to the personalized naming habits of different users for surgical instruments, thereby improving the recognition accuracy of target surgical instruments.

[0047] After the operation, the control module 16 automatically compares the instrument list and assists the instrument nurse to complete the inventory to prevent the omission of instruments, thus realizing the intelligent inventory of surgical instruments.

[0048] As can be seen from the above, an embodiment of the present application provides an intelligent surgical instrument table system, which binds a first unit one-to-one to a surgical instrument, stores the instrument information of the surgical instrument, and embeds a plurality of second units arranged in a horizontal array on the table top of the surgical instrument table. The second unit can communicate wirelessly with the first unit. Based on this, the instrument information can be obtained through the second unit, the corresponding surgical instrument can be accurately and automatically identified, and the surgical instrument can be two-dimensionally positioned. At the same time, the surgical instrument can be dynamically tracked in three dimensions in combination with the visual tracking module, realizing real-time positioning of the surgical instrument for the first time. In addition, a list of surgical instruments is generated before and after the operation and automatically compared, realizing intelligent inventory of surgical instruments for the first time.

[0049] In summary, the embodiment system of the present application realizes the accurate automatic identification, real-time positioning and intelligent inventory of surgical instruments for the first time through the collaborative work of RFID, NFC, visual tracking and AR technologies, thereby improving the efficiency and safety of the surgical process and solving the technical problem that the existing surgical assistance system can only identify surgical instruments but cannot dynamically locate and intelligently count surgical instruments.

[0050] Obviously, those skilled in the art may make various changes and modifications to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include these modifications and variations.
