Abstract
Description
Technical Field
[0001] This application relates to the field of medical device data processing technology, and in particular to a method, apparatus, equipment and medium for temperature control of an intelligent surgical instrument table. Background Technology
[0002] Wound cleaning is a widely used treatment method that plays an important role in intraoperative wound management. During the operation, intraoperative irrigation solution can be used to clean the surgical site and reduce the risk of surgical infection.
[0003] The relevant technology involves preheating the irrigation fluid in a warming chamber to maintain a constant temperature. When the irrigation fluid is needed during surgery, it is taken out of the warming chamber and used. However, in actual surgery, the patient's body temperature may drop suddenly. In this case, the temperature of the irrigation fluid in the warming chamber may be higher than the temperature of the patient's tissue. Continuing to use the irrigation fluid at a temperature higher than the patient's tissue temperature may cause vasodilation and massive bleeding due to the high temperature. It is evident that improper temperature control of the irrigation fluid in this technology can easily increase the risk of massive bleeding in surgical patients. Summary of the Invention
[0004] To improve the rationality of irrigation fluid temperature control, this application provides a method, device, equipment, and medium for temperature control of an intelligent surgical instrument table.
[0005] In a first aspect, this application provides a method for temperature control of an intelligent surgical instrument table, employing the following technical solution: A method for temperature control of an intelligent surgical instrument table, comprising:
[0006] The system acquires the patient's surgical parameters, surgical site identification, and current surgical time, and predicts the patient's hypothermia information based on the surgical parameters. The hypothermia information includes: hypothermia temperature value and the time of hypothermia.
[0007] Obtain the current temperature value and flushing fluid information;
[0008] Based on the current temperature value, the low temperature value, and the surgical site identification, the temperature adjustment information of the irrigation fluid is determined. The temperature adjustment information includes whether the temperature needs to be adjusted and the temperature adjustment value, or whether the temperature does not need to be adjusted.
[0009] When the temperature adjustment information indicates that the temperature needs to be adjusted, the heating power of the heating device is determined based on the heating duration, the irrigation fluid information, and the temperature adjustment value. The heating duration is the time difference between the current surgical time and the time when the low temperature is located.
[0010] A temperature control signal is generated based on the heating time and the heating power to control the heating device to heat the rinsing fluid. The heating device is set on the surgical instrument table.
[0011] By employing the above technical solution, surgical parameters, surgical site identification, and the current surgical time are obtained. Based on the surgical parameters, the patient's hypothermia information is predicted to determine the patient's hypothermia value and the time of that value during surgery. The current temperature of the irrigation fluid and its heating information are then obtained. Different surgical patients have different wound conditions, resulting in different temperature requirements for the irrigation fluid. Furthermore, different hypothermia values necessitate adjustments to the irrigation fluid temperature. Therefore, the temperature adjustment value of the irrigation fluid needs to be determined based on the current temperature, hypothermia temperature, and surgical site identification to effectively improve the accuracy of the temperature adjustment value. The heating power is then determined based on the heating duration, heating information, and temperature adjustment value to achieve accurate heating of the irrigation fluid. A temperature control signal is generated based on the heating duration and heating power for heating. Compared to related technologies that place the irrigation fluid in a heating chamber, this application regulates the irrigation fluid temperature based on the surgical site identification and predicted hypothermia value, effectively improving the rationality of the irrigation fluid temperature regulation.
[0012] In a preferred embodiment, this application can be further configured such that determining the temperature adjustment information of the irrigation fluid based on the current temperature value, the low temperature value, and the surgical site identifier includes:
[0013] Based on the preset correspondence between surgical site identifiers and standard temperatures, and the surgical site identifiers, the standard temperature corresponding to the surgical site identifiers is determined;
[0014] Determine the temperature difference between the standard temperature and the low temperature value, and determine whether the temperature difference is greater than a preset temperature difference threshold.
[0015] If the temperature difference is greater than the preset temperature difference threshold, then the temperature adjustment information of the rinsing fluid is determined to be the temperature that needs to be adjusted.
[0016] When the temperature adjustment information of the flushing fluid is the required temperature, the temperature adjustment value of the flushing fluid is determined based on the standard temperature and the current temperature value.
[0017] By adopting the above technical solution, different surgical sites have different temperature requirements. Therefore, the standard temperature corresponding to the surgical site is determined according to the correspondence between the surgical site marking and the standard temperature. Targeted determination of the standard temperature effectively improves the accuracy of temperature adjustment information. When the patient's body temperature does not change significantly, the surgical site does not require temperature control. Otherwise, temperature control is required, thus necessitating the determination of the temperature difference and the comparison with the preset temperature difference threshold. When temperature adjustment is required, the temperature adjustment value of the irrigation fluid is determined based on the standard temperature and the current temperature value to adjust the irrigation fluid to the standard temperature. Adjusting the irrigation fluid to the standard temperature effectively reduces the increased risk of massive bleeding due to excessively high irrigation fluid temperature.
[0018] In a preferred embodiment, this application may be further configured such that obtaining the current temperature value of the rinsing fluid includes: obtaining an infrared image of the rinsing fluid, and determining the radiation intensity information of the rinsing fluid based on the infrared image;
[0019] The infrared emissivity of the rinsing fluid is obtained, and the current temperature value of the rinsing fluid is determined based on the radiation intensity information and the infrared emissivity.
[0020] By adopting the above technical solution, an infrared image of the flushing fluid is obtained, and the radiation intensity information of the flushing fluid is determined; then, the infrared emissivity of the flushing fluid is obtained, and the current temperature value of the flushing fluid is determined based on the radiation intensity information and the infrared emissivity. Compared with the related technology that determines the temperature of the flushing fluid by means of a temperature measuring device, this application can realize the real-time determination of the current temperature value of the flushing fluid by means of an infrared image. Moreover, the temperature measuring device can only detect the temperature of a part of the flushing fluid and cannot realize the accurate determination of the temperature of the entire flushing fluid area. This application effectively improves the accuracy of the flushing fluid temperature determination by means of an infrared image.
[0021] In a preferred embodiment, this application can be further configured such that predicting the patient's hypothermia information based on the surgical parameters includes:
[0022] The surgical parameters are normalized to obtain normalized surgical parameters;
[0023] The normalized surgical parameters are input into a preset hypothermia prediction model to obtain the patient's hypothermia information.
[0024] By adopting the above technical solution, different surgical parameters have different numerical units, so it is necessary to normalize the surgical parameters to effectively improve the calculation efficiency. The low temperature prediction model has the characteristic of high accuracy. Therefore, inputting the normalized surgical parameters into the preset low temperature prediction model to obtain the patient's low temperature information can improve the accuracy of the predicted low temperature information while improving the calculation efficiency.
[0025] In a preferred embodiment, this application may be further configured such that, after inputting the normalized surgical parameters into a preset hypothermia prediction model to obtain the patient's hypothermia information, the method further includes:
[0026] From a preset surgical site identifier information database, low-temperature information fitting curves corresponding to the surgical site identifiers are selected. The preset surgical site identifier information database includes: multiple surgical site identifiers and their respective low-temperature information fitting curves.
[0027] The target low temperature value is matched with the low temperature information fitting curve corresponding to the surgical site identification to determine the verification low temperature time corresponding to the target low temperature value, which is predicted by the low temperature prediction model; the target low temperature time is verified based on the verification low temperature time, which is predicted by the low temperature prediction model.
[0028] By adopting the above technical solution, a low-temperature information fitting curve corresponding to the surgical site identification is selected from the preset surgical site identification information database to obtain a more accurate low-temperature information fitting curve; then, the target low-temperature value is matched with the low-temperature information fitting curve to obtain the time of verification of the low temperature. By using the time of verification of the low temperature, the accuracy of the low-temperature information determination is effectively improved.
[0029] In a preferred embodiment, this application can be further configured such that the rinsing fluid information includes: specific heat capacity of the rinsing fluid, volume of the rinsing fluid, and container information of the container holding the rinsing fluid; when the temperature adjustment information indicates that temperature adjustment is required, determining the heating power of the heating device based on the heating duration, the rinsing fluid information, and the temperature adjustment value includes:
[0030] When the temperature adjustment information indicates that the temperature needs to be adjusted, the liquid identification information of the rinsing fluid is obtained, and the mass of the rinsing fluid is determined based on the liquid identification information and the volume of the rinsing fluid.
[0031] The heating power of the heating device is determined based on the specific heat capacity of the rinsing fluid, the mass of the rinsing fluid, the container information, the heating time, and the temperature adjustment value.
[0032] By adopting the above technical solution, when the temperature adjustment information indicates that the temperature needs to be adjusted, the liquid identification information of the irrigation fluid is obtained. Different types of irrigation fluids are used in surgery, and different types of irrigation fluids have different densities. Therefore, it is necessary to obtain the irrigation fluid identification information in order to accurately determine the quality of the irrigation fluid based on the irrigation fluid identification information. Then, the heating power of the heating device is determined based on the specific heat capacity of the irrigation fluid, the quality of the irrigation fluid, the container information, the heating time, and the temperature adjustment value, so as to effectively improve the accuracy of the heating power determination.
[0033] In a preferred embodiment, this application can be further configured such that obtaining the surgical site identifier of the patient includes: acquiring surgical images based on a preset image acquisition interval, and determining the patient's first location information based on the surgical images;
[0034] Obtain the facial features of the surgeon corresponding to the patient, and determine the second location information of the surgeon in the surgical image based on the surgical image and the facial features;
[0035] Based on the first location information and the second location information, the patient's surgical site is identified.
[0036] By adopting the above technical solution, when multiple body parts of a patient need to be operated on during an operation, and the surgical site is obstructed due to the large number of medical staff, it is necessary to acquire surgical images according to a preset image acquisition interval to determine the patient's surgical site at the current moment. Then, the patient's first location information is determined, and the surgeon's second location information is determined based on the surgeon's appearance and the surgical images. The surgical site identifier is determined based on the first and second location information, so as to determine the surgical site identifier in real time through the surgeon's position, which effectively improves the accuracy of surgical site identifier determination.
[0037] Secondly, this application provides a temperature control device for an intelligent surgical instrument table, employing the following technical solution: A temperature control device for an intelligent surgical instrument table, comprising:
[0038] The prediction module is used to acquire the patient's surgical parameters, surgical site identification, and current surgical time, and based on the surgical parameters, predict the patient's hypothermia information, which includes: hypothermia temperature value and the time of hypothermia.
[0039] The acquisition module is used to acquire the current temperature value and information of the flushing fluid.
[0040] The temperature adjustment information determination module is used to determine the temperature adjustment information of the irrigation fluid based on the current temperature value, the low temperature value, and the surgical site identifier. The temperature adjustment information includes whether the temperature needs to be adjusted or not. When the temperature adjustment information indicates that the temperature needs to be adjusted, the heating power determination module is triggered.
[0041] The heating power determination module is used to determine the heating power of the heating device based on the heating duration, the irrigation fluid information, and the temperature adjustment value, wherein the heating duration is the time difference between the current surgical time and the time when the low temperature is located;
[0042] A heating module is used to generate a temperature control signal based on the heating duration and the heating power to control the heating device to heat the rinsing fluid. The heating device is mounted on the surgical instrument table.
[0043] Thirdly, this application provides an electronic device that adopts the following technical solution:

[0047] Fourthly, this application provides a computer-readable storage medium, which adopts the following technical solution:
[0048] A computer-readable storage medium having a computer program stored thereon, which, when executed in a computer, causes the computer to perform a temperature control method for an intelligent surgical instrument table as described in any of the first aspects.
[0049] In summary, this application includes the following beneficial technical effects:
[0050] This invention acquires surgical parameters, surgical site identification, and the current surgical time. Based on the surgical parameters, it predicts the patient's hypothermia information to determine the patient's hypothermia value and the time of that value during surgery. It also acquires the current temperature of the irrigation fluid and its heating information. Different surgical patients have different wound conditions, resulting in different temperature requirements for the irrigation fluid. Furthermore, different hypothermia values necessitate adjustments to the irrigation fluid temperature. Therefore, the temperature adjustment value of the irrigation fluid needs to be determined based on the current temperature, hypothermia temperature, and surgical site identification to effectively improve the accuracy of the temperature adjustment value. The heating power is then determined based on the heating duration, heating information, and temperature adjustment value to achieve accurate heating of the irrigation fluid. A temperature control signal is generated based on the heating duration and heating power for heating. Compared to related technologies that place the irrigation fluid in a heating chamber, this application regulates the irrigation fluid temperature based on the surgical site identification and predicted hypothermia value, effectively improving the rationality of the irrigation fluid temperature regulation.

[0055] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 This application will be described in further detail.
[0056] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of this application.
[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0058] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.
[0059] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.
[0060] This application provides a method for temperature control of an intelligent surgical instrument table, executed by an electronic device, which is a server. The server can be a standalone physical server, a server cluster consisting of multiple physical servers, or a distributed system, but is not limited to these. The server can be directly or indirectly connected via wired or wireless communication. This application does not impose any limitations on this method. Figure 2 As shown, the method includes steps S101, S102, S103, S104, and S105, wherein:
[0061] Step S101: Obtain the patient's surgical parameters, surgical site identification, and current surgical time, and predict the patient's hypothermia information based on the surgical parameters. The hypothermia information includes: hypothermia temperature value and the time of hypothermia.
[0062] Specifically, the surgical parameters include the patient's body mass index (BMI), operating room ambient temperature, and anesthesia time. These parameters are pre-input by technicians. The patient's BMI is closely related to their physical condition, which in turn is correlated with hypothermia at the surgical site. Due to heat transfer, the operating room ambient temperature also affects the temperature of the surgical site. During surgery, the longer the anesthesia time, the higher the probability of hypothermia at the surgical site. Therefore, in this embodiment, BMI, operating room temperature, and anesthesia time are selected as the surgical parameters to predict hypothermia information, effectively improving the accuracy of hypothermia determination. The surgical site identifier is the name of the surgical site or a corresponding number. This identifier can be acquired by an image acquisition device and identified by an electronic device. The image acquisition device can be installed anywhere within the operating room. The current surgical time is determined by the electronic device based on an electronic clock. The following embodiment illustrates how to predict patient hypothermia information based on surgical parameters. Understandably, when the temperature of the surgical site is too low during surgery, it indicates that the patient is facing a certain life-threatening situation. At this time, using irrigation fluid to transfer heat to the surgical site can effectively improve the safety of the patient's surgery. By predicting the patient's low temperature information in advance, the irrigation fluid can be heated in time to provide the patient with irrigation fluid at a suitable temperature.
[0063] Step S102: Obtain the current temperature value and flushing fluid information of the flushing fluid.
[0064] Specifically, the current temperature of the irrigation fluid can be determined by acquiring its infrared image using an image acquisition device and analyzing the infrared image using an electronic device. The irrigation fluid information includes: the specific heat capacity of the irrigation fluid, the volume of the irrigation fluid, and the container information, including: the container area and the container's heat transfer coefficient. It is understood that, based on practical considerations, the container for carrying the irrigation fluid in this embodiment is a transparent container. The specific heat capacity of the irrigation fluid is determined based on the irrigation fluid and pre-input into the electronic device; different irrigation fluids have different specific heat capacities. The volume of the irrigation fluid before use can be pre-input into the electronic device by the technician. The volume of irrigation fluid used during the surgery can be detected by sensors in the instrument table, transmitted to the electronic device, and analyzed by the electronic device. The heat transfer coefficient and surface area of the container carrying the irrigation fluid are both pre-input into the electronic device by the technician.
[0065] Step S103: Based on the current temperature value, the low temperature value, and the surgical site identification, determine the temperature adjustment information of the irrigation fluid. The temperature adjustment information includes whether the temperature needs to be adjusted or not.
[0066] Specifically, when the temperature of the patient's surgical site changes only slightly during surgery and the patient is not in life-threatening danger, the temperature change can be ignored, and the corresponding temperature adjustment information is "no adjustment required." However, when the temperature of the patient's surgical site changes significantly during surgery, the patient may be in life-threatening danger. In this case, irrigation fluid can be used to adjust the temperature, meaning the temperature adjustment information is "temperature adjustment required." Furthermore, during the use of irrigation fluid, because the mucous membranes of human internal tissues are thin, using irrigation fluid with a high temperature may cause massive bleeding at the surgical site. Therefore, it is necessary to determine a temperature adjustment value to allow for temperature adjustment while avoiding excessive bleeding caused by overheating, effectively improving the rationality of temperature control. When the temperature adjustment information indicates "temperature adjustment required," step S104 is executed; when the temperature adjustment information indicates "temperature adjustment not required," the electronic device continues to predict the patient's low temperature.
[0067] Step S104: When the temperature adjustment information indicates that the temperature needs to be adjusted, the heating power of the heating device is determined based on the heating duration, the rinsing fluid information, and the temperature adjustment value. The heating duration is the time difference between the current surgical time and the time when the low temperature is located.
[0068] Specifically, such as Figure 2 As shown, Figure 2 This is a schematic diagram of a smart surgical instrument table provided in an embodiment of this application. The surgical instrument table and the patient operating table (SA2) are adjacent. A heating device is installed on the surgical instrument table for heating the irrigation fluid. Figure 2 SA1 is the area where the heating device is located. The container holding the rinsing fluid and the rinsing fluid can be placed above this area for heating. The heating device can be wirelessly connected to electronic equipment, allowing the electronic equipment to control the heating device to heat the rinsing fluid.
[0069] Step S105: Generate a temperature control signal based on the heating time and heating power to control the heating device to heat the rinsing fluid. The heating device is set on the surgical instrument table.
[0070] Specifically, after determining the heating time and heating power, the electronic device can generate corresponding temperature control information and send it to the heating device wirelessly. After receiving the temperature control signal, the heating device performs heating based on the temperature control signal.
[0071] In this embodiment, surgical parameters, surgical site identification, and current surgical time are acquired. Based on the surgical parameters, the patient's hypothermia information is predicted to determine the patient's hypothermia value and the time of the hypothermia value during surgery. The current temperature of the irrigation fluid and its heating information are then acquired. Different surgical patients have different wound conditions, resulting in different temperature requirements for the irrigation fluid. Furthermore, different hypothermia values require different irrigation fluid temperatures for adjustment. Therefore, the temperature adjustment value of the irrigation fluid needs to be determined based on the current temperature, hypothermia temperature, and surgical site identification to effectively improve the accuracy of the temperature adjustment value. The heating power is then determined based on the heating duration, heating information, and temperature adjustment value to achieve accurate heating of the irrigation fluid. A temperature control signal is generated based on the heating duration and heating power for heating. Compared to related technologies that place the irrigation fluid in a heating chamber, this application regulates the irrigation fluid temperature based on the surgical site identification and predicted hypothermia value, effectively improving the rationality of the irrigation fluid temperature regulation.
[0072] One possible implementation of this application embodiment includes step S103, which determines the temperature adjustment information of the irrigation fluid based on the current temperature value, the low temperature value, and the surgical site identifier, including:
[0073] Based on the preset correspondence between surgical site markings and standard temperatures, and the surgical site markings, the standard temperature corresponding to the surgical site markings is determined.
[0074] Determine the temperature difference between the standard temperature and the low temperature value, and determine whether the temperature difference is greater than the preset temperature difference threshold.
[0075] If the temperature difference is greater than the preset temperature difference threshold, the temperature adjustment information of the flushing fluid is determined to be that the temperature needs to be adjusted.
[0076] When the flushing fluid temperature adjustment information indicates that temperature adjustment is required, the flushing fluid temperature adjustment value is determined based on the standard temperature and the current temperature value.
[0077] Specifically, it is understood that different internal human tissues have different temperature tolerances, and therefore the standard temperatures corresponding to different surgical sites are also different. For example, when the surgical site is the heart, the standard temperature for the heart should be 32°C; when the surgical site is the brain, the standard temperature corresponding to the brain can be 37°C. The preset correspondence between surgical site identifiers and standard temperatures can be set by technicians based on their work experience and stored in electronic devices. This application embodiment does not limit the specific content of the above correspondence, thereby obtaining the standard temperature corresponding to the surgical site identifier.
[0078] If the temperature difference exceeds the preset temperature difference threshold, it indicates that the patient's life is in danger and temperature adjustment using irrigation fluid is necessary. Therefore, it is necessary to determine the temperature difference, which can be calculated using the formula: Temperature Adjustment Value = Standard Temperature - Current Temperature. When the temperature difference is not greater than the preset temperature difference threshold, it indicates that the patient's body temperature has not changed significantly, meaning the patient is not in danger and temperature changes can be ignored.
[0079] In this embodiment, different surgical sites have different temperature requirements. Therefore, the standard temperature corresponding to the surgical site is determined according to the correspondence between the surgical site identification and the standard temperature. By determining the standard temperature in a targeted manner, the accuracy of temperature adjustment information is effectively improved. When the patient's body temperature does not change significantly, the patient's surgical site does not need temperature control. Otherwise, temperature control is required. Therefore, it is necessary to determine the temperature difference and judge the temperature difference and the preset temperature difference threshold. When the temperature needs to be adjusted, the temperature adjustment value of the irrigation fluid is determined according to the standard temperature and the current temperature value so as to adjust the irrigation fluid to the standard temperature. By adjusting the irrigation fluid to the standard temperature, the risk of increased massive bleeding due to excessively high irrigation fluid temperature can be effectively reduced.
[0080] In one possible implementation of this application embodiment, step S102, obtaining the current temperature value of the rinsing fluid, includes: obtaining an infrared image of the rinsing fluid, and determining the radiation intensity information of the rinsing fluid based on the infrared image;
[0081] The infrared emissivity of the flushing fluid is obtained, and the current temperature of the flushing fluid is determined based on the radiation intensity information and the infrared emissivity.
[0082] Specifically, infrared images can be acquired by an image acquisition device; the number of pixels in the infrared image and the radiation intensity value of each pixel are obtained; the average radiation intensity of the infrared image is determined based on the number of pixels and the radiation intensity value of each pixel; the infrared emissivity is pre-input into the electronic device by a technician; and the current temperature value can be obtained according to the temperature calculation formula. Where T is the current temperature of the flushing fluid, and σ is the Stefan-Boltzmann constant, σ = 1.380649 * 10 -23 J / K,
[0083] In this embodiment, an infrared image of the flushing fluid is acquired, and the radiation intensity information of the flushing fluid is determined. Then, the infrared emissivity of the flushing fluid is acquired, and the current temperature value of the flushing fluid is determined based on the radiation intensity information and the infrared emissivity. Compared with the related technology that determines the temperature of the flushing fluid by means of a temperature measuring device, this application can determine the current temperature value of the flushing fluid in real time by means of an infrared image. Moreover, the temperature measuring device can only detect the temperature of a part of the flushing fluid and cannot accurately determine the temperature of the entire flushing fluid area. This application effectively improves the accuracy of the flushing fluid temperature determination by means of an infrared image.
[0084] One possible implementation of this application embodiment includes step S101, which predicts the patient's hypothermia information based on surgical parameters, including:
[0085] The surgical parameters are normalized to obtain the normalized surgical parameters;
[0086] The normalized surgical parameters are input into a preset hypothermia prediction model to obtain the patient's hypothermia information.
[0087] Specifically, normalization can be performed using max-min normalization, standard deviation normalization, or decimal scaling normalization. This application does not limit the specific normalization method or process; users can set them themselves. It is understood that different surgical parameters have different units, thus requiring normalization for subsequent calculations.
[0088] Specifically, inputting surgical parameters into a cryogenic prediction model yields multiple cryogenic temperature values and their corresponding times of occurrence. The cryogenic prediction model can be trained based on multiple sample surgical parameters and a neural network model. The specific training process for the cryogenic prediction model may include: selecting target information, corresponding cryogenic temperature values, and times of occurrence for multiple surgical patients who have experienced cryogenic problems from a hospital surgical patient database; the target information includes surgical site identification and surgical parameters corresponding to the aforementioned surgical patients; inputting the target information into an untrained cryogenic prediction model to obtain multiple sample cryogenic information; calculating the loss value between the sample cryogenic information and the actual cryogenic information corresponding to the sample surgical parameters using a preset loss function; and training the untrained cryogenic prediction model based on the aforementioned loss value and a preset loss threshold until the loss value reaches the preset loss threshold; and using the untrained cryogenic prediction model that reaches the preset loss threshold as the preset cryogenic prediction training model. Absolute value loss function, squared loss function, or logarithmic loss function can be used. The preset loss threshold is set by technicians based on their work experience and input into the electronic device. This application embodiment does not limit the specific loss function and the preset loss function threshold; users can set them themselves. Understandably, determining the exact time of hypothermia can serve a preventative purpose, allowing for the use of an appropriate temperature irrigation solution to regulate the temperature before hypothermia occurs at the surgical site, thus ensuring the patient's safety.
[0089] In this embodiment, different surgical parameters have different numerical units, so the surgical parameters need to be normalized to effectively improve computational efficiency. The low temperature prediction model has the characteristic of high accuracy, so inputting the normalized surgical parameters into the preset low temperature prediction model to obtain the patient's low temperature information can improve the accuracy of low temperature prediction while improving computational efficiency.
[0090] One possible implementation of this application embodiment, after inputting the normalized surgical parameters into a preset hypothermia prediction model to obtain the patient's hypothermia information, further includes:
[0091] From the preset surgical site identification information database, the low temperature information fitting curves corresponding to the surgical site identification are selected. The preset surgical site identification information database includes multiple surgical site identifications and their corresponding low temperature information fitting curves.
[0092] The target low temperature value is matched with the low temperature information fitting curve corresponding to the surgical site to determine the time of verification low temperature corresponding to the target low temperature value. The target low temperature value is predicted by the low temperature prediction model.
[0093] The target low temperature time is verified based on the time of the verified low temperature, which is predicted by the low temperature prediction model.
[0094] Specifically, the low-temperature information fitting curves corresponding to the multiple surgical site identifiers are obtained and drawn by technicians based on their work experience. Each low-temperature information fitting curve includes multiple low-temperature values and their corresponding low-temperature times. Each surgical site corresponds to one low-temperature information fitting curve. This application embodiment does not limit the specific drawing process of the low-temperature information fitting curves, thus obtaining the low-temperature information fitting curves corresponding to the surgical site identifiers. The target low-temperature value is then matched with the low-temperature information fitting curve to obtain the verification low-temperature time corresponding to the target low-temperature value. The verification low-temperature time is then used to verify the target low-temperature time. The verification process includes: calculating the time difference between the verification low-temperature time and the target low-temperature time, determining whether the time difference is not greater than a preset time difference threshold. If so, the target low-temperature time is determined to be accurate and can be identified as the low-temperature time in the patient's low-temperature information. If not, the target low-temperature time is determined to be inaccurate. In this case, a preset number of low-temperature information predictions are re-executed based on the surgical parameters. After completing the preset number of predictions, if the low-temperature information has not changed, the low-temperature information predicted by the low-temperature prediction model is identified as the patient's low-temperature information, and the aforementioned low-temperature information fitting curve is modified. This application does not limit the preset time difference threshold or the preset number of times, which can be set by technicians based on their work experience. In another possible implementation, the time when the target low temperature is located can be matched with the low temperature information fitting curve to determine the verification low temperature value, and the verification low temperature value can be used to verify the target low temperature value. The verification process is the same as the verification process for the time when the target low temperature is located, and will not be described again in this application.
[0095] In this embodiment, a low-temperature information fitting curve corresponding to the surgical site identification is selected from a preset surgical site identification information database to obtain a more accurate low-temperature information fitting curve; then, the target low-temperature value is matched with the low-temperature information fitting curve to obtain the time of verification of the low temperature. By using the time of verification of the low temperature, the accuracy of the low-temperature information determination is effectively improved.
[0096] One possible implementation of this application embodiment includes the following: the rinsing fluid information includes the specific heat capacity of the rinsing fluid, the volume of the rinsing fluid, and the container information of the container holding the rinsing fluid. When the temperature adjustment information indicates that temperature adjustment is required, the heating power of the heating device is determined based on the market to be heated, the rinsing fluid information, and the temperature adjustment value, including:
[0097] When the temperature adjustment information indicates that the temperature needs to be adjusted, the liquid identification information of the flushing fluid is obtained, and the flushing fluid quality is determined based on the liquid identification information and the flushing fluid volume.
[0098] The heating power of the heating device is determined based on the specific heat capacity of the rinsing fluid, the mass of the rinsing fluid, the container information, the heating time, and the temperature adjustment value.
[0099] Specifically, the heating power of the heating device can be calculated using the heating power calculation formula. It is understood that when the rinsing fluid is used for the first time, the volume information of the rinsing fluid can be directly obtained from the rinsing fluid information database, and then calculated using the formula: m = ρv, where m is the mass of the rinsing fluid, ρ is the density of the rinsing fluid, and v is the volume of the rinsing fluid. The density of the rinsing fluid can be obtained from the rinsing fluid density information database based on the rinsing fluid identifier, and the mass of the rinsing fluid can be determined through calculation. The liquid identifier can be the name of the rinsing fluid. When the rinsing fluid is used again, the volume of the rinsing fluid changes. At this time, the volume of the rinsing fluid can be determined by acquiring the surface area and height of the rinsing fluid using an image acquisition device, and the mass of the rinsing fluid can be calculated using the above formula. The heating power is then calculated using the heating power calculation formula, where the heating power calculation formula is: Where c is the specific heat capacity of the rinsing fluid, m is the mass of the rinsing fluid, ΔT is the temperature adjustment value, k is the heat transfer coefficient of the container holding the rinsing fluid, and s is the surface area of the container holding the rinsing fluid. Thus, the heating power of the heating device can be obtained.
[0100] In this embodiment, when the temperature adjustment information indicates that the temperature needs to be adjusted, the liquid identification information of the irrigation fluid is obtained. Different types of irrigation fluids are used in surgery, and the densities of different types of irrigation fluids are different. Therefore, it is necessary to obtain the irrigation fluid identification information in order to accurately determine the quality of the irrigation fluid based on the irrigation fluid identification information. Then, the heating power of the heating device is determined based on the specific heat capacity of the irrigation fluid, the quality of the irrigation fluid, the container information, the heating time, and the temperature adjustment value, so as to effectively improve the accuracy of the heating power determination.
[0101] In one possible implementation of this application embodiment, step S101 obtains the surgical site identifier of the patient, including: acquiring surgical images based on a preset image acquisition interval, and determining the patient's first location information based on the surgical images;
[0102] Obtain the facial features of the surgeon corresponding to the patient, and determine the second location information of the surgeon in the surgical image based on the surgical image and facial features;
[0103] Based on the first and second location information, the patient's surgical site is identified.
[0104] Specifically, it is understood that in the same surgery, there may be situations where multiple different parts of the patient's body are operated on. Furthermore, during the surgery, the surgical site may be obstructed due to the large number of medical staff, making it impossible to directly determine the surgical site from the image. Therefore, it is necessary to acquire surgical images according to a preset image acquisition interval. The surgical images are acquired by an image acquisition device. This application embodiment does not limit the preset image acquisition interval; the user can set it themselves. The image acquisition device uploads the acquired images to an electronic device. The electronic device can build a three-dimensional model of the operating room based on the surgical images and establish a three-dimensional coordinate system with any point in the three-dimensional model as the origin. This allows for the acquisition of a set of three-dimensional coordinates corresponding to the patient, i.e., the first position information. A complete three-dimensional image of the patient can be drawn using this set of three-dimensional coordinates. The appearance characteristics of the surgeon corresponding to the patient can be obtained from the patient information database. These appearance characteristics may include the surgeon's height or body type. The surgical images are then used to identify the surgeon among all medical staff. Furthermore, the second position information of the surgeon can be determined from the aforementioned three-dimensional coordinate system. A complete three-dimensional image of the surgeon can be drawn using the set of three-dimensional coordinates corresponding to the surgeon, i.e., the second position information. Furthermore, the patient's height can be determined based on the patient's initial location information. Based on the height and its correspondence with various body parts, the location information of each body part can be determined. This location information is then matched with the second location information. When the location information of a body part overlaps with the second location information, that body part is identified as the patient's current surgical site, and the corresponding site identifier is designated as the surgical site identifier. The aforementioned height and its correspondence with various body parts can be established by technicians based on experience.
[0105] In this embodiment of the application, when multiple body parts of a patient need to be operated on during an operation, and the surgical site is obstructed due to the large number of medical staff, it is necessary to acquire surgical images according to a preset image acquisition interval to determine the patient's surgical site at the current moment; then, the patient's first location information is determined, and the surgeon's second location information is determined based on the surgeon's appearance and the surgical images; the patient's surgical site identifier is determined based on the first and second location information, so as to determine the surgical site identifier in real time through the surgeon's position, which effectively improves the accuracy of surgical site identifier determination.
