Description

Technical Field

[0001] The present invention belongs to the field of medical appliances, and more specifically, particularly relates to a counting and disinfection integrated surgical gauze counting device and a counting method. Background Art

[0002] Gauze is an essential consumable during the surgical process, used for operations such as wiping blood, cleaning the wound, and compressing to stop bleeding. After use, it needs to be collected uniformly, and the number of gauzes needs to be counted after the operation to prevent gauze from being left behind. Usually, the counting method is often carried out manually. However, under long-term high-intensity operations, the used gauzes are somewhat messy, which easily leads to counting mistakes, thus causing unnecessary panic; in order to avoid gauze being left behind, a surgical gauze counting device is needed.

[0003] A surgical gauze counting device is a device that counts the number of surgical gauzes and simplifies the counting process, which can effectively avoid the omissions and errors easily occurring in manual counting and greatly improve the counting efficiency of surgical gauzes; however, traditional counting devices usually only have a single counting function and cannot disinfect the used surgical gauzes, resulting in the easy spread of germs in subsequent transportation and storage links, which will pose a certain threat to the safety of medical staff and the environment; at the same time, traditional counting devices mostly use simple photoelectric sensors to count gauze individuals. When foreign objects enter the device together with the gauze, since the foreign objects will also block the light, the photoelectric sensors cannot effectively distinguish between gauze and foreign objects, and then generate counting signals, which not only easily leads to abnormal counting but may also pose serious safety hazards during the surgical process. Summary of the Invention

[0026] A counting method for a counting and disinfection integrated surgical gauze counting device, which is applied to the above-mentioned counting and disinfection integrated surgical gauze counting device, includes the following steps:

[0027] Obtain the initial weight data of the overall gauze before use, the individual quantity of the collected gauze, and the final weight data of the overall gauze after use;

[0028] Based on the initial and final weight data and the gauze individual count, construct a weight change evaluation model to evaluate the rationality of the weight change of the gauze from before use to after use, and assist in judging whether there are abnormalities in the collection link; combined with the weight change reference data after the gauze is contaminated with liquid, set a weight change threshold range, take the difference between the final and initial weight data as the weight change value, and compare it with the threshold range to evaluate the rationality of the gauze weight change;

[0029] If the weight change value is within the threshold range, it is determined that the counting and the gauze status are normal; if it exceeds the range, obtain the gauze image information after collection and analyze whether there are abnormal objects; combined with the image analysis results, the gauze individual count and the weight data, re-judge the accuracy of the gauze count and the reason for the weight abnormality.

[0030] According to a preferred implementation manner, constructing the weight change evaluation model includes:

[0031] Collect the weight change data of the gauze used in different types of surgeries before and after being contaminated with different liquids, clean the collected data to remove outliers and incorrect data, and establish a database;

[0032] Classify and organize the data according to the surgical type, gauze size and material factors, and use data analysis algorithms to calculate the mean and standard deviation of the weight change of the gauze under different categories.

[0033] According to a preferred implementation manner, when the weight change value exceeds the weight change threshold range, through image acquisition, identify the gauze contour in the image, preliminarily determine the quantity of the gauze through the contour quantity, and analyze the abnormal state of the gauze;

[0034] Meanwhile, identify whether there are objects in the image with significant differences from the gauze characteristics; transmit the image analysis results to the controller, and the controller makes a judgment by combining the gauze individual count and weight data. If the number of gauzes in the image does not match the gauze individual count and there are abnormal objects, it is determined that the count is incorrect and foreign objects are mixed in. If the number of gauzes matches, but there are serious damages or adhesions that affect the weight judgment, the controller adjusts the weight evaluation result according to the gauze status.

[0035] According to a preferred embodiment, based on the image analysis results, combined with the gauze individual count and weight data, re-evaluate the accuracy of the gauze individual count and the reasons for weight abnormalities. If the image analysis finds that the number of gauzes is inconsistent with the gauze individual count, take the number of gauzes analyzed by the image as the standard and correct the gauze individual count.

[0036] If there are abnormal objects in the image, deduct the weight of the abnormal objects from the final weight data, recalculate the weight change value, and compare it with the weight change threshold range. If the recalculated weight change value is within the threshold range, it is determined that the count and the gauze status are normal. If it still exceeds the threshold range, check whether there are faults in the collection component and the storage component.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The device forms a disinfection chamber through the bottom box and the main body housing. An ultraviolet lamp and a plasma generator are installed on the collection component in the chamber to achieve timely disinfection of the used gauze. The collection channel composed of the collection funnel, the connecting pipeline and the inclined plate, in cooperation with the photoelectric sensors on the support rod and the inclined plate, can accurately record the number of gauzes entering the collection box. The weight sensor in the placement plate can obtain the gauze weight data to assist in counting, realizing the integration of the counting and disinfection functions, effectively avoiding the spread of germs, reducing the use of additional disinfection equipment, and improving the convenience and efficiency of medical work.

[0039] 2. The semi-circular mounting plate on the rotating disk of the collection component and the collection box with multiple open surfaces not only facilitate the collection of gauze but also enable the gauze to be fully exposed to ultraviolet disinfection. The through holes on the peripheral side of the collection box, the through grooves on the mounting plate and the rotating disk, and the second through groove of the support plate cooperate to form a blanking channel, which facilitates the disinfected gauze to fall into the bottom box storage component, optimizing the gauze collection, disinfection and transfer processes and improving the overall work efficiency. In the connecting pipeline, through the air outlet component and the fan, an air wall can be formed in the connecting pipeline. There is a gap between the air wall and the connecting pipeline. When the gauze enters the connecting pipeline, due to the action of the air wall, the gauze will not come into contact with the inner wall of the connecting pipeline, thereby reducing the pollution of the connecting pipeline by the gauze and lowering the risk of germs attaching to the inner wall of the pipeline and breeding and spreading. Moreover, the air wall can also blow off some of the liquid on the surface of the gauze, avoiding liquid residue causing pipeline corrosion. At the same time, the wind force generated by the air wall can push the gauze to quickly pass through the connecting pipeline, improving the collection efficiency and making the entire gauze collection process more efficient and hygienic, effectively ensuring the cleanliness and safety of the medical environment.

[0040] 3. In terms of counting accuracy, by obtaining the weight parameter to calculate the change value and comparing it with the threshold, combined with image analysis, considering gray-scale parameters, foreign objects, etc., it avoids counting errors caused by liquid contamination, damage, etc., and ensures reliable statistics. In terms of foreign object detection, after a series of processes of image analysis and combined with template matching, foreign objects are accurately identified. After detecting foreign objects, the weight is recalculated for judgment to prevent foreign objects from being left behind and reduce the surgical risk. In the surgical process, automated and intelligent counting, quick analysis and judgment in case of abnormalities, saving time and improving efficiency, and timely reminding to check the device when the counting is abnormal. In addition, the definitions of each parameter are clarified to reduce operation errors caused by inconsistent understandings, and improve the operability and management efficiency of the system.

[0055] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the technical solutions of the present invention, but cannot be used to limit the protection scope of the present invention.

[0056] Embodiment:

[0057] As Figures 1 to 12As shown in the figure, the present invention provides a counting and disinfection integrated surgical gauze counting device, which includes a bottom box 11, a plurality of ultraviolet lamps 21 and a plasma generator 22. The bottom box 11 is connected to the main body housing 12, and the two enclose a disinfection chamber, which provides a safe and efficient environment for subsequent disinfection work. The plasma generator 22 can adopt the Shandong Xinhua PS-100GXP plasma generator. The collection component arranged in the disinfection chamber is rotatably connected to the bottom box 11, which not only facilitates the rotation of the collection component but also ensures its stability. A plurality of ultraviolet lamps 21 and the plasma generator 22 are installed on the collection component. When the collection component rotates, the ultraviolet lamps 21 and the plasma generator 22 can disinfect the gauze on the collection component in all directions, improving the disinfection effect and efficiency. One end of the connecting pipeline on the main body housing 12 is connected to the collection funnel 31, and the other end is connected to the inclined plate 32. The three together constitute a collection channel. The collection funnel 31 is designed with a larger opening shape to facilitate the gauze used during the operation to quickly enter the collection channel. A plurality of photoelectric sensors 42 are installed on the support rod 41 on one side of it and the inclined plate 32. The photoelectric sensor 42 on the support rod 41 determines the number of gauze by detecting the number of times of reaching. After the gauze is used, it needs to be placed into the collection funnel 31, and during the placement process, it needs to pass through the photoelectric sensor 42 on the support rod 41, thereby realizing the counting operation of the gauze. The photoelectric sensor 42 on the inclined plate 32 directly detects the gauze. It utilizes the advanced principles of light reflection and refraction. When the gauze passes through the inclined plate 32, the light emitted by the sensor will produce reflection and refraction phenomena on the surface of the gauze. The sensor can judge the number of gauze by analyzing these light changes, providing double guarantee for the counting of surgical gauze. The photoelectric sensor 42 can adopt the Turck RO20M-BS18-VP6X2E-H1141 photoelectric sensor. A placement box 44 is placed on the placement plate 43 on one side of the collection funnel 31. A weight sensor 45 is arranged in the placement plate 43, which can measure the weight of the gauze in the placement box 44, providing important data support for subsequent counting and status evaluation. The weight sensor 45 can adopt the METTLER TOLEDO IND560. The storage component inside the bottom box 11 moves through a plurality of slide rails 13, enabling the storage component to adjust its position conveniently for the medical staff to operate. A controller is also arranged in the device, which is not shown in the figure. Through the controller, each component can be intelligently controlled to realize the coordinated work of a series of functions such as counting, disinfection, and storage, and display various data. At the same time, a plurality of vision modules 511 are arranged in the bottom box 11. Each vision module 511 is equipped with a high-resolution camera and an advanced image processor, which can collect images of the collected gauze from different angles.The vision module 511 performs operations such as noise reduction, enhancement, and segmentation on the collected images in sequence, identifies the number of gauzes, the damage condition, and the presence of foreign objects, and feeds back the analysis results to the device main control system in real time to assist in counting and status assessment. The controller is electrically connected to the photoelectric sensor 42, the weight sensor 45, and the vision module 511, so that the controller can receive the signals transmitted by the two. The photoelectric sensor 42 monitors the pulse signal generated when the gauze passes through the collection channel, and the weight data of the gauze collected by the weight sensor 45 in real time is transmitted to the controller. The algorithm installed in the controller analyzes and processes these signals, which can not only accurately count the number of gauzes, but also judge the usage status of the gauzes based on the weight change, providing data support for the management of surgical gauzes, and the controller can adopt the Advantech ADAM-6050 controller.

[0058] As Figure 2 , Figure 3 shown, the collection component includes a support plate 501 and a rotating disk 502. The support plate 501 is stably installed above the bottom box 11, providing a support foundation for the entire collection component. The rotating disk 502 is rotatably connected to the support plate 501, effectively improving the flexibility of the collection component. The semi-circular mounting plate 503 on the rotating disk 502 can be disassembled as needed to adapt to different scenarios. The collection frame 504 on the mounting plate 503 has multiple opening surfaces, which not only facilitates the collection of gauzes, but also allows the gauzes to be fully disinfected by the ultraviolet lamp 21, ensuring the efficient progress of the collection and disinfection work of surgical gauzes in all directions. The multiple sets of detachable semi-circular mounting plates 503 provided on the rotating disk 502 have a semi-circular shape design. On the one hand, it saves space and enables the collection component to be reasonably arranged in the limited disinfection chamber; on the other hand, this shape is more convenient for the installation and fixation of the collection frame 504. Medical staff can easily replace or adjust the mounting plate 503 according to actual needs, facilitating the collection of surgical gauzes of different specifications. Multiple sets of collection frames 504 are provided above the mounting plate 503. The collection frame 504 is provided with multiple opening surfaces. One set of opening surfaces faces upward and contacts the end of the inclined plate 32, so that the used gauzes can slide from the inclined plate 32 into the collection frame 504, realizing efficient collection. Another set of opening surfaces faces the ultraviolet lamp 21, and the collection frame 504 is located within the radiation range of the ultraviolet lamp 21. Multiple sets of through holes are also opened on the periphery of the collection frame 504, so that the gauzes in the collection frame 504 can be fully disinfected by ultraviolet rays, and the presence of the through holes helps air circulation, avoiding the growth of germs due to a humid environment. The multiple sets of first through grooves opened on the mounting plate 503 and the rotating disk 502, and the second through grooves opened on the support plate 501 together form a blanking channel, which penetrates the disinfection chamber and the bottom box 11. The problem of the transfer of disinfected gauzes is solved. The disinfected gauzes can automatically fall into the storage component in the bottom box 11 through the blanking channel, realizing an integrated and coherent operation from collection, disinfection to storage, and improving work efficiency.

[0059] As Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 shown, the storage component is mainly composed of a storage frame 505 and a storage board 506. The storage frame 505 can move forward and backward, left and right through multiple groups of sliding rails 13, ensuring that the storage frame 505 can move smoothly and can adjust the storage position according to actual needs at any time. The weight sensor 45 is installed on the storage frame 505, and the bearing plate is placed on the weight sensor 45, which can monitor the weight change of the storage board 506 and the gauze placed on it in real time, providing data support for counting. Multiple groups of electromagnets 507 are arranged on the bearing plate. When the storage board 506 is placed on the bearing plate, the electromagnets 507 are energized to generate magnetic force, tightly adsorbing the storage board 506 and fixing it on the bearing plate, effectively preventing the storage board 506 from shifting or shaking during the movement process and ensuring the stability of storage. Multiple groups of storage boxes 508 are arranged on the storage board 506, and the openings are designed in a horn shape and face upward. This unique shape facilitates the putting in and taking out of gauze, improving the operation convenience. The blanking pipe 509 is arranged at the bottom of the support plate 501, and a group of storage boxes 508 corresponds to it directly below. This enables the disinfected gauze to directly fall into the corresponding storage box 508 through the blanking pipe 509, realizing seamless connection and improving the efficiency of gauze storage. Multiple groups of electric covers 510 in the collection frame 504 form a covering structure as the bottom plate. The electric covers 510 can be automatically opened and closed according to control instructions. When the collection frame 504 is full of gauze, the electric covers 510 close, sending the gauze into the disinfection chamber for disinfection. After disinfection is completed, they open again, enabling the gauze to fall into the storage box 508 through the blanking pipe 509. The whole process has a high degree of automation and reduces the complexity of manual operation.

[0060] The vision module 511 is installed at the bottom of the support plate 501. The identification plate 512 on the storage board 506 is strip-shaped and coated with multiple colors. Each color corresponds to a group of storage boxes 508, and the colors are gradually changed; meanwhile. When the vision module 511 can also identify the identification plate 512, the camera quickly captures images. Through the algorithm analyzing the color characteristics, it can quickly determine the position and status of the storage box 508. For example, if the color corresponding to a certain group of storage boxes 508 changes color or fades, the vision module 511 can detect it in time and prompt for maintenance. At the same time, through the vision module 511, image recognition of the gauze in the storage box 508 can be carried out. Its algorithm can judge whether the gauze is neatly placed and whether there are abnormal states such as damage and stains according to the contour, color and other characteristics of the gauze. If an abnormality is found, it can immediately feedback to the controller, facilitating medical staff to handle it in time and improving the accuracy and efficiency of surgical gauze management.

[0061] The first limiting plates 513 on both sides of the storage plate 506 and the second limiting plate 514 at one end form a placement area with the storage box 508. The transparent cover plate 515 can be clamped in the placement area, and the digital labels on the cover plate 515 correspond to the storage boxes 508 one by one, which is convenient for medical staff to intuitively understand the information of each storage box 508, realizes visual management, and improves the accuracy and efficiency of gauze management.

[0062] As Figure 2 , Figure 5 , Figure 6 , Figure 9 shown, the connecting pipeline is mainly composed of multiple groups of first connecting pipes 61 and second connecting pipes 62. The multiple groups of first connecting pipes 61 are vertically distributed and are connected end to end with each other, constructing a stable and continuous transmission channel, which not only ensures the smooth passage of gauze in the pipeline, but also enhances the structural stability of the entire connecting pipeline. One end of the lowermost first connecting pipe 61 is tightly clamped in the second connecting pipe 62, and one end of the uppermost first connecting pipe 61 is connected to the collection funnel 31, so that the gauze entering from the collection funnel 31 can smoothly enter the connecting pipeline and start the subsequent processing process. The inclined plate 32 is provided with a feeding end and a discharging end. The feeding end is located at the bottom of the connecting pipeline and is detachably connected to the second connecting pipe 62. The discharging end of the inclined plate 32 is in contact with the collection assembly, which is convenient for accurately conveying the collected gauze to the collection assembly. Multiple groups of driving blocks 63 are also arranged on the inclined plate 32. The driving blocks 63 are rotatably connected to the inclined plate 32, and the driving blocks 63 can rotate automatically by themselves. When the gauze enters the inclined plate 32, the lowermost driving block 63 rotates to block the falling of the gauze; when continuous gauze drops, the driving blocks 63 on the inclined plate 32 rotate one after another to limit the gauze until the bottom storage assembly rotates in place and the driving blocks 63 are restored, and the gauze drops into the storage assembly. A photoelectric sensor 42 is installed near the feeding end to detect the passing quantity of the gauze and provide accurate data for counting.

[0063] In the connecting pipeline, an air outlet component is arranged below a group of first connecting pipes 61. The air outlet component is clamped between multiple groups of first connecting pipes 61. Multiple groups of air outlet pipes 64 arranged thereon are located inside the first connecting pipes 61 and are respectively close to the inner walls of the first connecting pipes 61. Multiple groups of fans 65 on the main body housing 12 provide wind power support for the air outlet pipes 64. One group of fans 65 is connected to multiple groups of air outlet pipes 64 through a conduit. The air outlet openings with inclined bottoms of the air outlet pipes 64 face the inclined plate 32, forming a wind wall with a downward wind direction. A gap is formed between the wind wall and the inner walls of the first connecting pipes 61 and the second connecting pipes 62. When the gauze enters the connecting pipeline, the wind wall can prevent the gauze from contacting the inner wall of the pipeline, reducing the pollution of the pipeline by the gauze. At the same time, it can also blow off some of the liquid on the surface of the gauze, avoiding pipeline corrosion caused by liquid residue. The wind power generated by the wind wall can also push the gauze to quickly pass through the connecting pipeline, improving the collection efficiency. The wind receiving plates 66 arranged around the inner side of the second connecting pipe 62 are connected to each other on both sides of multiple groups of wind receiving plates 66, forming a wind receiving cavity. The end of the wind wall is located in the wind receiving cavity, and multiple groups of air outlet slots opened on the second connecting pipe 62 communicate the wind receiving cavity with the disinfection cavity. Such a design can not only guide the air flow of the wind wall, but also send the impurities and germs carried by the wind wall into the disinfection cavity through the air outlet slots for treatment, further ensuring the cleanliness inside the device.

[0064] A heating module arranged at one end of one group of fans 65 is sleeved on the conduit. An air guide pipe 67 arranged at one end of the collection funnel 31 is connected to another group of fans 65. The heating module can heat the air passing through the conduit, so that the wind wall has a certain temperature, which helps to dry the moisture on the surface of the gauze and prevent bacteria from breeding in a humid environment. The air guide pipe 67 blows towards the inner bottom surface of the collection funnel 31. When collecting the gauze, it can preliminarily clean and dry the gauze in the collection funnel 31 to ensure that the gauze entering the connecting pipeline is in a relatively clean state. The heating module is a general heating module.

[0065] As Figure 11 、 Figure 12 shown, a counting method of a counting and disinfection integrated surgical gauze counting device is applied to the above-mentioned counting and disinfection integrated surgical gauze counting device, including the following steps:

[0066] S1: Obtain the individual quantity parameter, initial weight parameter and final weight parameter of the gauze, and obtain the weight change value parameter by subtracting the initial weight parameter from the final weight parameter;

[0067] Specifically, the individual quantity parameter is to record the quantity of gauze individuals entering the collection box 504 through the collection channel by using the optoelectronic sensor 42. The optoelectronic sensor 42 is installed on the collection channel and can quickly detect the passing situation of the gauze. Every time a piece of gauze passes, the optoelectronic sensor 42 will generate a signal, and the counting module accumulates the signal quantity, thereby recording the quantity of gauze entering the collection box 504, so as to timely master the usage situation of gauze during the operation, avoid gauze omission or overuse, and ensure the smooth progress of the operation.

[0068] The initial weight parameter is the total weight of the surgical gauze in the placement box 44 and is the starting point of the entire counting method. The initial weight parameter is obtained through the weight sensor 45 to provide a benchmark for subsequent weight change analysis.

[0069] The final weight parameter is the total weight of the used gauze in the storage box 508 in the storage component. The data uses the weight sensor 45 again to obtain the final weight parameter and conducts a comparative analysis with the initial weight parameter before the operation.

[0070] Obtain the weight change value parameter. Specifically, perform a subtraction operation on the initial weight parameter and the final weight parameter:

[0071] W = F - I

[0072] Where W represents the weight change value parameter, F is the final weight parameter, and I is the initial weight parameter. Through the weight change value, it can intuitively reflect the situation of the gauze absorbing substances such as liquid during the operation, and further help medical staff understand information such as the amount of bleeding and the amount of exudate during the operation, and assist in judging the progress of the operation and the physical condition of the patient.

[0073] S2: Set the weight change threshold and perform a comparison operation based on the weight change threshold and the weight change value parameter;

[0074] Compare the weight change value parameter with the set weight change threshold range to determine whether the gauze counting and status are normal. The weight change threshold is specifically set by combining the weight change reference data after the gauze is contaminated with liquid under different surgical types and adopting an algorithm framework that combines integrated learning and deep learning;

[0075] First, collect the weight change data of the gauze used in a large number of different types of surgeries before and after being contaminated with different liquids, and establish a comprehensive and detailed database. These data cover various surgical scenarios, gauze materials, and liquid types, providing a rich information basis for subsequent analysis.

[0076] In the data processing stage, use the DBSCAN algorithm for preliminary clustering. This algorithm divides data points into core points, boundary points, and noise points based on the density distribution of the data points. Its core formula is as follows:

[0077] Neighborhood Definition: Given a dataset D, let ρ ∈ D, ε be the neighborhood radius, and the ε-neighborhood N ε (p) of point ρ is defined as:

[0078] N ε (p) = {q ∈ D | G(p, q) ≤ ε}.

[0079] Among them, G(p, q) is the distance metric function. In this paper, the Euclidean distance is adopted:

[0080]

[0081] Core Point Judgment: If |N ε (p)| ≥ MinPts, then point p is a core point, where MinPts is the minimum number of points threshold.

[0082] Density Direct Reach and Density Reachability: q ∈ N ε (p) and p is a core point, then q is density directly reachable from p; if there exists a point sequence p1, p2,...., p n , where p1 = p, p n = q, and p i+1 is density directly reachable from p i , then q is density reachable from p.

[0083] Through these definitions, the DBSCAN algorithm can automatically identify different data clusters, effectively avoiding the subjectivity of manual classification and laying a foundation for more accurate subsequent analysis. However, to further improve the accuracy and adaptability of classification, we introduce the Variational Autoencoder (VAE) algorithm based on deep learning. VAE can capture complex non-linear relationships in the data by learning the latent space representation of the data. It can map high-dimensional weight change data to a low-dimensional space, automatically extracting the key features of the data while retaining the distribution information of the data during this process. This enables not only more accurate classification of data for different surgical types, gauze sizes, and materials, but also discovery of hidden patterns and regularities in the data.

[0084] For the classified data, statistical analysis methods are used to calculate the mean and standard deviation of the gauze weight changes under different categories; at the same time, to more reasonably set the threshold range, an adaptive threshold adjustment algorithm is introduced. This algorithm is based on the principle of reinforcement learning, continuously trying different threshold settings and optimizing the threshold according to the feedback information to make it more in line with the actual situation. For example, in practical applications, the algorithm will dynamically adjust the threshold according to factors such as the urgency of the surgical type and the hospital's infection control standards. For surgeries with a higher infection risk, the threshold range is appropriately narrowed to more strictly monitor the gauze weight changes; for emergency surgeries, the threshold range is appropriately widened on the premise of ensuring safety to ensure the smooth progress of the surgery.

[0085] Taking a small debridement operation as an example, such as superficial wound debridement or small area burn debridement, through the comprehensive analysis of the above algorithm, the weight change threshold range is set to ±20% of the initial weight. This is because the blood loss in small debridement operations is relatively small, and the amount of liquid contaminated by the gauze is relatively stable. A smaller threshold range can effectively detect abnormal situations. For large-scale surgical operations, such as coronary artery bypass grafting or liver transplantation, considering factors such as large blood loss and long operation time, the weight change threshold range is set to ±50% of the initial weight.

[0086] S31: If the weight change value parameter is less than or equal to the weight change threshold, it is determined to be normal;

[0087] When obtaining the result that the weight change value parameter is less than or equal to the weight change threshold, it is determined that the gauze count is normal, and S4 is executed for further operations.

[0088] S32: If the weight change value parameter is greater than the weight change threshold, it is determined that the individual quantity parameter of the gauze is abnormal, and image analysis operations are performed;

[0089] Specifically: When obtaining the result that the weight change value parameter is greater than the weight change threshold, it is determined that the counting parameter of the gauze is abnormal. In order to further judge the gauze, image analysis operations are performed on the collected gauze;

[0090] The image information of the gauze is obtained through the vision module 511, and the obtained gauze image is subjected to Gaussian blur and grayscale processing to obtain a preprocessed image; among them, through grayscale processing, the gauze grayscale parameter;

[0091] If the gauze grayscale parameters are arranged in a uniform distribution, it is determined that the gauze is normal. For example, the grayscale parameters are [1, 2, 3, 4, 5], the parameters increase uniformly, and the difference between adjacent parameters is stable, without large increases or decreases. This indicates that the gauze has stable characteristics in the image, and there are no obvious foreign object interferences or abnormal situations. At this time, it shows that the gauze state meets the expectations, and it can be determined that the count and the gauze state are normal, and subsequent corresponding steps such as normal count statistics can be continued, and step S4 is executed.

[0092] If the gauze grayscale parameters are arranged in a stepped pattern, it is determined that there may be foreign objects. For example, the grayscale parameters are [1, 2, 3, 8, 9]. Starting from the fourth item "8", the difference from the previous item "3" significantly exceeds the normal fluctuation range between adjacent parameters, showing a stepped mutation. It is possible that foreign objects have mixed in, changing the original stable grayscale distribution of the gauze. By calculating the difference between adjacent parameters at the location where the stepped change occurs, the degree of abnormal grayscale change can be quantified, thereby obtaining the grayscale difference value parameter, which provides key data support for subsequent foreign object detection.

[0093] Based on the threshold segmentation algorithm, according to the gray-scale difference value parameter, the suspected target area is extracted; specifically, after obtaining the gray-scale difference value parameter, it is used as an important basis to apply the threshold segmentation algorithm. The core of this algorithm lies in setting a reasonable gray-scale threshold, which is related to the gray-scale difference value parameter.

[0094] For example, taking the gauze image used in an abdominal surgery as an example, after obtaining the gray-scale difference value parameters of this gauze image, we deeply analyze the distribution characteristics and variation laws of these parameters. It is found that the gray-scale difference value is relatively stable in most areas, but in the lower right corner of the image, the gray-scale difference value fluctuates greatly. By statistically analyzing data such as the mean and standard deviation of the gray-scale difference value in this area, and at the same time combining the clustering algorithm in machine learning to classify the gray-scale difference value of the entire image. After multiple iterations and optimizations, a threshold suitable for the current image characteristics is dynamically determined.

[0095] When the gray-scale value of a certain area in the image reaches or exceeds the set threshold compared with the gray-scale difference value of the surrounding area, this area is marked as a suspected target area. In this example, in the area with large fluctuations in the gray-scale difference value in the lower right corner of the image, the difference between its gray-scale value and the surrounding area exceeds the set threshold, so this area is marked as a suspected target area, providing a key area to be analyzed for subsequent foreign object identification and judgment.

[0096] Obtain the preset foreign object feature template, and match it with the suspected target area based on the preset foreign object feature template to judge whether there is a foreign object; specifically: the preset foreign object feature template is constructed by collecting a large number of image samples of common foreign objects in surgery (such as surgical instrument fragments, cotton ball residues, thread ends), and using advanced image processing and machine learning technologies to extract their features. These templates cover multi-dimensional feature information such as the color, texture, and shape of the foreign objects.

[0097] After obtaining the suspected target area, use a feature matching algorithm (such as feature point-based matching algorithms SIFT, SURF, etc.) to carefully compare the preset foreign object feature template with the suspected target area. During the matching process, the algorithm will calculate the similarity score between the template features and the suspected target area features. By continuously adjusting the matching parameters, the accuracy and robustness of the matching are improved, so as to judge whether there is a foreign object in this area.

[0098] If the matching degree reaches the preset threshold, it is determined that there is a foreign object, and the weight change value is recalculated. Specifically, the preset threshold is a value determined through repeated calibration based on a large amount of experimental data and simulation tests, and is used to measure the similarity between the suspected target area and the preset foreign object feature template. For example, in an experiment simulating a common surgical scenario, the features of different types of foreign object samples are extracted, and a large number of gauze images containing foreign objects are generated. The suspected target areas in these images are matched with the foreign object feature template. After multiple tests, when the similarity score given by the matching algorithm reaches 80% or more, the foreign object can be accurately identified through subsequent verification. Therefore, 80% is set as the preset threshold.

[0099] When the matching degree reaches the preset threshold, the suspected target area is highly similar to the preset foreign object feature template, and it can be determined that there is a foreign object in this area. The presence of the foreign object will affect the actual weight of the gauze, so it is necessary to recalculate the weight change value.

[0100] The specific operation of recalculating the weight change value is as follows: If the matching degree reaches the preset threshold and it is determined that there is a foreign object, the weight of the foreign object is deducted from the final weight parameter to obtain the recalculated weight change value.

[0101] W R = F - I - A

[0102] Where W R represents the recalculated weight change value parameter, F is the final weight parameter, I is the initial weight parameter, and A is the weight of the abnormal object.

[0103] Based on the comparison operation between the recalculated weight change value and the weight change threshold, re-judge whether the counting is normal. If the recalculated weight change value is less than or equal to the weight change threshold, it indicates that after deducting the weight of the foreign object, the actual weight change of the gauze is within a reasonable range. This shows that after excluding the influence of the foreign object, the usage situation of the gauze meets the expectations and there is no abnormality in the counting process. At this time, it is determined that the counting is normal, and step S4 can be executed according to the established process.

[0104] If the recalculated weight change value is greater than the weight change threshold, even after deducting the weight of the foreign object, the weight change of the gauze still exceeds the reasonable range, and there may be an abnormal situation. The reasons for this may be various. For example, the sensor of the counting device fails, resulting in inaccurate weight data acquisition; or there are omissions or duplicate counting problems during the gauze collection process; it is also possible that other components of the device are damaged or malfunction.

[0105] S4: Obtain the normal counting parameter of the gauze based on the comparison operation and the individual quantity parameter.

[0106] Specifically: The individual quantity parameter refers to the total quantity recorded when the gauze passes through the optoelectronic sensor 42, which is the basic data for counting. After determining that the counting is normal, the individual quantity parameter will be strictly reviewed. During the review process, the integrity and accuracy of the data will be checked to exclude possible mis-counting situations. For example, check whether the working state of the optoelectronic sensor 42 is normal and whether there is signal interference resulting in repeated counting or missed counting.

[0107] Based on the results of the above comparison operations and the reviewed individual quantity parameter, through calculation and data integration, the normal gauze counting parameter is finally obtained; the normal gauze counting parameter is the individual quantity parameter after determining that the counting is normal through this series of comparison operations. It not only accurately reflects the actual quantity of gauze used during the operation but also provides a reliable basis for subsequent medical records, statistical analysis, and quality control, etc., which helps to improve the quality and safety of medical services.

[0108] The above shows and describes the basic principles, main features, and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
