[0062] In order to make the purpose, technical solution and beneficial effects of this application clearer, the technical solution in the embodiment of this application will be clearly and completely described below in conjunction with the drawings in the embodiment of this application. Obviously, the described embodiment is only a part of the embodiment of this application, not all the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] The present application embodiment provides a hysteroscopic surgery early warning method, see Figure 1 As shown, the overview process of the hysteroscopic surgery early warning method provided in the embodiment of the present application is as follows:

[0064] Step 101: Acquire real-time electrocoagulation and electroresection data, real-time negative or insufficient amount of uterine distention fluid, and current operation type; wherein, the real-time electrocoagulation and electroresection data are the real-time electrocoagulation pedal pressure of the hysteroscopic electrocoagulation control pedal and the real-time electroresection pedal pressure of the hysteroscopic electroresection control pedal; the real-time negative or insufficient amount of uterine distention fluid is determined by the real-time infusion weight and the real-time outflow weight of the uterine distention fluid.

[0065] In actual applications, the types of surgeries include: hysteroscopic electroresection, intrauterine adhesion separation, myomectomy, hysteroscopic tubal insufflation, hysteroscopic endometriosis treatment, hysteroscopic embryo retrieval, and hysteroscopic foreign body removal. The current type of surgery is at least one of the types of surgeries. A first pressure sensor is provided at the bottom of the hysteroscopic electrocoagulation control pedal, and the pressure collected in real time by the first pressure sensor is used as the real-time electrocoagulation pedal pressure. A second pressure sensor is provided at the bottom of the hysteroscopic electroresection control pedal, and the pressure collected in real time by the second pressure sensor is used as the real-time electroresection pedal pressure. Since the hysteroscope can only work in electrocoagulation or electroresection mode, at the same time, at least one of the real-time electrocoagulation pedal pressure and the real-time electroresection pedal pressure is zero. A first weight sensor is provided on the distension fluid injection device, and a second weight sensor is provided on the distension fluid collection device. The weight collected in real time by the first weight sensor is the real-time injection weight of the distension fluid, and the weight collected in real time by the second weight sensor is the real-time outflow weight of the distension fluid. The real-time negative or negative weight of the distension fluid is determined by subtracting the real-time outflow weight from the real-time injection weight at the same time, and the real-time negative or negative amount of the distension fluid is determined according to the real-time negative or negative weight and density of the distension fluid.

[0066] Step 102: input the real-time electrocoagulation and electroresection data and the real-time negative underflow into the negative underflow prediction model to obtain the predicted negative underflow outputted by the negative underflow prediction model.

[0067] In practical applications, the negative underflow prediction model can be an observation model based on a machine learning method, and specifically, a neural network model can be used. The negative underflow prediction model can output the predicted negative underflow at the first time in the future based on the input real-time electrocoagulation and electroresection data and the real-time negative underflow of the uterine distention fluid. The first time is after the future time and separated from the future time by a preset time interval.

[0068] Step 103: Based on the preset mapping relationship between the surgery type, the first warning level and the first warning threshold range, obtain the first warning level corresponding to the current surgery type and the first warning threshold range corresponding to the first warning level.

[0069] Step 104: taking the first type of warning level corresponding to the threshold range to which the predicted under-volume belongs as the predicted warning level, and executing the warning operation corresponding to the level of the predicted warning level.

[0070] In actual applications, each type of surgery corresponds to a first-class warning level and a first-class warning threshold range; each first-class warning level is set with a corresponding first-class warning threshold range. The first-class warning level is the level of warning for predicted negative underflow, which can be divided into multiple levels. The first-class warning threshold range is the warning threshold range for predicted negative underflow, which can include multiple non-overlapping negative underflow ranges. Each level in the first-class warning level corresponds to a negative underflow range. As the level of the first-class warning level increases, the corresponding negative underflow range segment increases, and the predicted risk of excessive absorption of uterine distension fluid gradually increases; each level of the first-class warning level corresponds to different warning operations. Specifically, the first-class warning level can include the first-class level 1 warning, the first-class level 2 warning, and the first-class level 3 warning. The warning operation corresponding to the first-level warning of the first category is to display the predicted warning level and the predicted negative amount, light up the corresponding indicator light or make the indicator light display the corresponding color; the warning operation corresponding to the first-level warning of the first category is to display the predicted warning level and the predicted negative amount, light up the corresponding indicator light, make a sound alarm, and issue a voice prompt corresponding to the risk of excessive absorption of uterine distention fluid, so that the doctor can adjust the surgical operation in time; the warning operation corresponding to the first-level warning of the third category is to display the predicted warning level and the predicted negative amount, light up the corresponding indicator light, make frequent sound alarms, and issue a voice prompt corresponding to the high risk of excessive absorption of uterine distention fluid, so that the doctor can adjust the surgical operation in time. In the case of a large number of first-level warning levels, multiple level thresholds can also be set, and the first-level warning levels within each level threshold range match the same warning operation, and the first-level warning levels within different level threshold ranges match different warning operations.

[0071] In a possible implementation, after obtaining the electrocoagulation and electroresection data, the uterine distention fluid data, and the current operation type, the method further includes:

[0072] Firstly, based on the historical under-volume and the real-time under-volume, the real-time change value of the under-volume is determined;

[0073] Then, it is determined whether the real-time change value is greater than a preset change threshold; if so, an operation risk prompt is issued when the real-time electrocoagulation pedal pressure or the real-time electroresection pedal pressure is not zero.

[0074] In actual applications, the real-time change value of the negative underflow is the real-time negative underflow minus the historical negative underflow, and the real-time change value of the negative underflow is greater than the preset change threshold, which corresponds to a rapid increase in the negative underflow. The real-time electrocoagulation foot pressure or the real-time electroresection foot pressure is not zero, which means that the electrocoagulation and electroresection operation is currently being performed under hysteroscopy. When it is determined that the real-time change value of the negative underflow is greater than the preset change threshold and the real-time electrocoagulation foot pressure or the real-time electroresection foot pressure is not zero, it is determined that the electrocoagulation and electroresection operation causes a rapid increase in the negative underflow, and an operation risk prompt is performed, wherein the operation risk prompt corresponds to the situation where the electrocoagulation and electroresection operation causes a rapid increase in the negative underflow, and the operation risk prompt is at least one of a voice prompt that indicates that there is a risk of a rapid increase in the negative underflow with the current operation, the corresponding indicator light is lit, and the corresponding icon or text is displayed on the display. When it is determined that the real-time change value of the negative underflow is greater than the preset change threshold and the real-time electrocoagulation foot pressure and the real-time electroresection foot pressure are both zero, it is determined that other operations cause a rapid increase in the negative underflow, and other risk prompts are performed. Among them, other risk warnings correspond to situations where other operations cause a rapid increase in negative balance. Other risk warnings are at least one of the following means: voice prompts related to other factors that cause a rapid increase in negative balance, lighting of corresponding indicator lights, and display of corresponding icons or texts on the display.

[0075] In one possible implementation, see Figure 2 As shown in the figure, after obtaining the electrocoagulation and electroresection data, uterine distention fluid data and the current operation type, it also includes:

[0076] Step 201: Obtain the patient's case data and uterine distention fluid type; wherein the case data includes the patient's age, the patient's current condition, and the patient's underlying condition.

[0077] In actual application, the types of uterine distension fluid include electrolyte solutions and non-electrolyte solutions. The patient's current condition is the condition corresponding to the type of surgery. The patient's current condition includes: endometrial polyps, submucosal myomas and endometrial hyperplasia corresponding to hysteroscopic transurethral resection, intrauterine adhesions corresponding to intrauterine adhesion separation, intrauterine myomas corresponding to myomectomy, fallopian tube obstruction corresponding to hysteroscopic tubal insufflation, endometriosis corresponding to hysteroscopic endometriosis treatment, early miscarriage, incomplete miscarriage and missed miscarriage corresponding to hysteroscopic embryo retrieval; intrauterine foreign bodies, IUD incarceration, IUD breakage and IUD displacement corresponding to hysteroscopic foreign body retrieval. The patient's underlying condition refers to the condition that the patient has suffered for a long time.

[0078] Step 202: Input the patient's age, the patient's current condition, and the type of uterine distention fluid into the first threshold evaluation model to obtain the second warning level and the threshold range corresponding to the second warning level.

[0079] In actual applications, each second-class warning level is set with a corresponding second-class warning threshold range. The second-class warning level is the warning level for real-time negative under-volume, which can be divided into multiple levels. The second-class warning threshold range is the warning threshold range for real-time negative under-volume, which can include multiple non-overlapping negative under-volume ranges. Each level in the second-class warning level corresponds to a negative under-volume range. As the level of the second-class warning level increases, the actual risk of excessive absorption of uterine distention fluid increases.

[0080] In specific implementation, the first threshold evaluation model can output the corresponding second-class warning level and the threshold range corresponding to the second-class warning level according to the input patient age, patient current condition and uterine distention fluid type. The first threshold evaluation model can be a neural network model or a linear regression model. The first threshold evaluation model is trained in the following way.

[0081] First, a training set is obtained; wherein the training set includes multiple data groups, each data group includes the patient's age and the patient's current condition, and the age and / or condition in each data group are different.

[0082] Then, each data group in the training set is input into the first threshold evaluation model respectively to obtain the prediction result corresponding to each data group; wherein the prediction result includes the second type of warning level and the threshold range corresponding to the second type of warning level.

[0083] Finally, based on the prediction results and target results corresponding to each data group, the model parameters of the first threshold evaluation model are updated; wherein the target result is the second warning level corresponding to the data group in the training set and the threshold range corresponding to the second warning level.

[0084] Step 203: Determine a target threshold range corresponding to the second warning level based on the patient's basic symptoms and the threshold range corresponding to the second warning level.

[0085] In actual applications, since patients have different tolerances when they suffer from different underlying diseases, it can be determined whether to adjust the threshold range corresponding to the second warning level, and the adjustment range of the threshold range corresponding to the second warning level can be determined according to whether the patient's underlying disease belongs to the preset type of disease. Among them, the preset type of disease includes comorbidities such as cardiovascular disease and renal failure, and different preset types of diseases can correspond to different preset adjustment ranges.

[0086] Specifically, based on the patient's basic symptoms and the threshold range corresponding to the second warning level, the target threshold range corresponding to the second warning level is determined, which may be in the following ways but not limited to:

[0087] First, determine whether the patient's underlying disease belongs to the preset type of disease;

[0088] Then, if the patient's underlying condition belongs to the preset type of condition, the threshold range corresponding to each second-class warning level will be lowered, and the lowered threshold range will be used as the target threshold range corresponding to each second-class warning level; if the patient's underlying condition does not belong to the preset type of condition, the threshold range corresponding to each second-class warning level output by the first threshold assessment model will be used as the target threshold range corresponding to each second-class warning level.

[0089] Step 204: Based on the second warning level and the target threshold range corresponding to the second warning level, determine the second warning level corresponding to the real-time under-volume, and use the second warning level corresponding to the real-time under-volume as the second target warning level.

[0090] Step 205: Based on the correspondence between the second type of warning level and the warning operation, execute the warning operation corresponding to the second type of target warning level.

[0091] In actual applications, the second warning level is the warning level of real-time negative underflow, and the second warning level can include the second level one warning, the second level two warning, and the second level three warning. Each warning level corresponds to a warning operation. The warning operation corresponding to the second level one warning is to display the warning level and the real-time negative underflow, light up the corresponding indicator light or make the indicator light display the corresponding color; the warning operation corresponding to the second level one warning is to display the warning level and the real-time negative underflow, light up the corresponding indicator light or make the indicator light display the corresponding color, and issue a voice prompt corresponding to the current abnormal absorption of uterine distension fluid; the warning operation corresponding to the second level three warning is to display the warning level and the real-time negative underflow, light up the corresponding indicator light or make the indicator light display the corresponding color, issue a voice prompt corresponding to the current excessive absorption of uterine distension fluid, and control the uterine distension fluid injection device to stop injecting uterine distension fluid. As the second warning level increases, the intensity and frequency of the alarm sound will increase.

[0092] In one possible embodiment, since systemic absorption of fluid increases significantly when intrauterine pressure exceeds mean arterial pressure, to reduce the risk of excessive absorption of distending fluid, see Figure 3 As shown in the figure, after obtaining the electrocoagulation and electroresection data, uterine distention fluid data and the current operation type, it also includes:

[0093] Step 301: Obtain the patient's current intrauterine pressure and mean arterial pressure.

[0094] Step 302: Determine the difference between the intrauterine pressure and the mean arterial pressure as the pressure difference, and determine the ratio of the pressure difference to the mean arterial pressure as the pressure increase ratio.

[0095] Step 303: Based on the preset third warning level and the threshold range corresponding to the third warning level, determine the third warning level corresponding to the boost ratio, and use the third warning level corresponding to the boost ratio as the third target warning level.

[0096] Step 304: Based on the correspondence between the third type of warning level and the warning operation, execute the warning operation corresponding to the third type of target warning level.

[0097] In actual applications, the current intrauterine pressure is detected and sent by the distending fluid supply device, and the average pulsatile pressure is collected and sent by the external blood pressure monitoring device. The third category warning level includes the third category level 1 warning, the third category level 2 warning, and the third category level 3 warning. Correspondingly, the threshold range of the third category level 1 warning is 0~20%, the threshold range of the third category level 2 warning is 20~30%, and the threshold range of the third category level 3 warning is greater than 30%. Each warning level corresponds to an indicator light of a certain color. As the third category warning level increases, the intensity and frequency of the alarm sound will increase.

[0098] In a possible implementation, the hysteroscopic surgery early warning method further includes:

[0099] First, after the operation, all the electrocoagulation and electroresection data and uterine distention fluid data during the operation should be saved;

[0100] Then, based on all the electrocoagulation and electroresection data and uterine distention fluid data, an electrocoagulation and electroresection data-uterine distention fluid data image is drawn and saved;

[0101] Next, based on all the electrocoagulation and electroresection data, the behavioral data during the operation are determined, wherein the behavioral data includes the single duration, total number and total duration of the electroresection and electrocoagulation behaviors;

[0102] Finally, an association relationship between the current operation type, uterine distension fluid data, and behavior data is established, and the association relationship and the current operation type, uterine distension fluid data, and behavior data are saved.

[0103] In practical applications, all the electrocoagulation and electroresection data and uterine distention fluid data during the operation can be used to train the negative underflow prediction model. Based on the electrocoagulation and electroresection data and the negative underflow of uterine distention fluid during the entire operation, the electrocoagulation and electroresection data at the same time are used as the horizontal coordinate, and the real-time negative underflow of uterine distention fluid is used as the vertical coordinate to draw the electrocoagulation and electroresection data-uterine distention fluid negative underflow image, wherein the image includes multiple segment data curves, and the data curve can be a curve between the electrocoagulation foot pressure and the negative underflow or a curve between the electroresection foot pressure and the negative underflow. During the patient's operation of this type, the changing relationship between the electrocoagulation and electroresection data-uterine distention fluid data image intuitively shows the impact of electrocoagulation and electroresection behavior on negative underflow. The storage medium stores multiple groups of associations and the current operation type, uterine distention fluid data, and behavior data. For the data of the same current operation type, the uterine distention fluid data that meets the preset requirements can be screened out, and the corresponding behavior data can be obtained, the rules of the behavior data can be summarized, and the electrocoagulation and electroresection recommendations for the current operation type can be given.

[0104] In a possible implementation, the hysteroscopic surgery early warning method further comprises:

[0105] When the operation duration exceeds the preset duration, the warning for the operation will be stopped.

[0106] In a possible implementation, before obtaining real-time electrocoagulation and electroresection data, real-time negative and insufficient volume of uterine distention fluid, and the current operation type, it is necessary to train a negative and insufficient volume prediction model. The specific training method may be, but is not limited to, the following methods:

[0107] First, a training set is obtained; wherein the training set includes multiple groups of monitoring data, wherein each group of monitoring data includes electrocoagulation and electroresection data and negative or insufficient amount of uterine fluid at the same time;

[0108] Then, each set of monitoring data in the training set is input into the negative quantity shortage prediction model to obtain the negative quantity shortage prediction result corresponding to each set of monitoring data; wherein the negative quantity shortage prediction result includes the predicted negative quantity shortage at the first time after the collection time of the monitoring data;

[0109] Next, based on the negative quantity shortage prediction results and negative quantity shortage labeling results corresponding to each set of monitoring data, the loss function value is determined; wherein the negative quantity shortage labeling result is the actual negative quantity shortage at the first time after the monitoring data is collected;

[0110] Finally, based on the loss function value, the model parameters of the negative under-quantity prediction model are updated.

[0111] In the specific implementation, each group of monitoring data in the training set includes the electrocoagulation and electroresection data and the negative underflow of uterine fluid at the same time; the monitoring data in the training set can be obtained from all the electrocoagulation and electroresection data and uterine distention fluid data stored during the operation. The loss function can be one of the mean square error function, the root mean square error function, and the mean absolute error function. The loss function value output by the loss function can evaluate the difference between the negative underflow prediction result output by the negative underflow prediction model and the negative underflow description result. The smaller the loss function value, the higher the prediction accuracy of the negative underflow prediction model. Based on the loss function value, it is judged whether the loss function value is less than the preset threshold; wherein the preset threshold can be set according to actual needs. If the loss function value is not less than the preset threshold, the model parameters of the negative underflow prediction model are updated and retrained until the loss function value is less than the preset threshold to obtain the final negative underflow prediction model.
