Description

Technical Field

[0001] This application relates to the technical field of medical materials, and particularly to a method and system for monitoring liquid shunt suction based on the surgical process. Background Art

[0002] Currently, the suction bottles used in surgery, that is, the suction bottles in the negative pressure suction device, are mainly used to collect the liquids generated during the surgical process, such as blood, secretions, exudates, etc. These suction bottles are usually connected to a suction device and used in conjunction with it. Through the negative pressure effect of the suction device, the liquids in the surgical field are sucked out and stored in the suction bottle. Suction bottles are almost essential in the operating room and are used in various types of surgeries, including general surgery, obstetrics and gynecology, orthopedics, etc. They are also widely used in clinical departments such as the emergency room, intensive care unit, delivery room, etc. for clearing respiratory secretions or vomitus and collecting blood during rescue and treatment.

[0003] The existing method for monitoring liquid shunt suction based on the surgical process refers to connecting the suction tube to the suction device, placing the suction tube at an appropriate position in the surgical field according to the surgical needs, adjusting the negative pressure and suction intensity of the suction device according to the amount of liquid in the surgical field, and regularly checking the liquid volume in the suction bottle. When the liquid in the suction bottle reaches a certain height, the suction bottle is replaced in a timely manner. However, the existing method for monitoring liquid shunt suction based on the surgical process does not consider timely suction of the liquid in the surgical field, resulting in an unclear surgical field, affecting the surgical operation of the surgeon-in-charge. The accumulated fluid may compress the surrounding tissues or nerves, and the surgical safety of the patient during liquid shunt suction in the surgical process is relatively low, and there is room for improvement. Summary of the Invention

[0004] In order to improve the surgical safety of the patient during liquid shunt suction in the surgical process, this application provides a method and system for monitoring liquid shunt suction based on the surgical process.

[0005] A method for monitoring liquid shunt suction based on the surgical process provided by this application adopts the following technical solutions:

[0006] In a first aspect, a method for monitoring liquid shunt suction based on the surgical process includes the following steps:

[0007] Step S1, select and install a suction tube and a suction head according to the basic information of the patient to be measured and the surgical-related information, and verify the sealing performance;

[0008] Step S2, perform the surgery after receiving the result of the completion of preoperative preparation. Create a digital twin of the tissue structure based on the body tissue structure of the patient to be measured in the surgical field, and then obtain the regional division result by dividing the surgical field area of the patient to be measured;

[0009] Step S3: Based on the surgical-related information and the regional division results, simulate the liquid flow situation during the surgery to obtain the predicted liquid flow path information, and then determine whether barrier intervention is required. If so, perform barrier intervention;

[0010] Step S4: Real-time identify the liquid type during the surgery to obtain the real-time liquid generation type information. Based on the real-time liquid generation type information and the digital twin of the tissue structure, plan the suction path to obtain the liquid suction path information, and determine the suction residence time of the suction head at each position in the liquid suction path information to obtain the path node suction duration information;

[0011] Step S5: Determine the suction negative pressure and suction frequency according to the basic information of the patient to be tested and the surgical-related information. Based on the liquid suction path information, the path node suction duration information, the suction negative pressure, and the suction frequency, perform shunt suction. Adjust the suction negative pressure in real time according to the impurities and liquid viscosity in the suction liquid, and adjust the suction frequency in real time according to the liquid generation situation;

[0012] Step S6: Real-time detect the blood suction volume of the patient to be tested, and determine whether an alarm is required based on the blood suction volume. If so, output the surgical bleeding alarm result.

[0013] Preferably, obtain the basic information of the patient to be tested and the surgical-related information. The surgical-related information includes surgical type information, surgical scale information, and surgical wound site information. Determine the liquid type during the surgery according to the surgical type information to obtain the predicted liquid generation type information, and then determine the suction tube type information and the suction head type information.

[0014] Preferably, according to the surgical type information and the surgical wound site information of the patient to be tested, preset the liquid generation volume during the surgery to obtain the predicted liquid generation volume. Based on the liquid generation volume, determine the suction tube size and the suction head size.

[0015] Install the suction tube and the suction head on the negative pressure suction source. The negative pressure suction source, the suction tube, the suction head, and the suction bottle form a negative pressure shunt suction device. After installation, verify the sealing performance of the negative pressure shunt suction device. If the sealing performance is good, output the preoperative preparation completion result. If the sealing performance is poor, adjust the negative pressure shunt suction device until the sealing performance is good, and output the preoperative preparation completion result.

[0016] Preferably, when the result of preoperative preparation is received, the operation is performed. The operation field shooting information is obtained by shooting the operation process of the patient to be measured. The organizational structure height information is obtained through analysis based on the operation field shooting information. A digital twin of the organizational structure is created. The wound area is selected based on the digital twin of the organizational structure and the operation wound site information. The area with a lower structural composition in the operation field is judged to obtain the low-position area of the operation field. The weak part of the tissue in the operation field shooting information is marked as the weak area.

[0017] Preferably, it is judged whether there is self-generated liquid. If there is, the result of self-interference is output, and the information of the self-produced liquid part is marked. If not, the result of no self-interference is output.

[0018] When the patient to be measured generates different types of liquid, the operation wound site information and the self-produced liquid part information of the patient to be measured are marked as the liquid generation source. Based on the low-position area of the operation field and the liquid generation source, the first predicted liquid flow path information is obtained by simulating the liquid flow situation during the operation. It is judged whether the blood type and other liquid types are fused. If they are not fused, the result of negative barrier intervention is output. If they are fused, the result of positive barrier intervention is output. When the result of positive barrier intervention is received, the barrier intervention is performed.

[0019] Preferably, the real-time liquid generation type information is obtained by detecting the liquid type during the operation in real time. After the barrier intervention, the second predicted liquid flow path information is obtained by simulating the liquid flow situation in the patient to be measured based on the low-position area of the operation field, the liquid generation source, and the barrier intervention position information. The second predicted liquid flow path information is adjusted and updated in real time based on the real-time liquid generation type information.

[0020] Based on the second predicted liquid flow path information, the suction path of the suction head is planned to obtain the liquid suction path information. According to the area division result and the organizational structure height information, the suction stay duration of the suction head at each position in the liquid suction path information is judged to obtain the path node suction duration information.

[0021] Preferably, the suction negative pressure is determined according to the basic information of the patient to be measured, the suction frequency is determined according to the operation-related information. Shunt suction is performed based on the liquid suction path information, the path node suction duration information, the suction negative pressure, and the suction frequency. The suction negative pressure is adjusted in real time according to the liquid viscosity and impurities. The liquid generation situation during the operation is detected to obtain the liquid generation parameter information. The preset suction frequency is adjusted in real time based on the liquid generation parameter information.

[0022] Preferably, a blood loss threshold is determined according to the basic information of the patient to be measured, the liquid level height of the aspirated blood during the operation is detected to obtain blood aspiration height information, the blood aspiration volume is calculated based on the blood aspiration height information, and it is determined whether an alarm is needed based on the blood aspiration volume. If so, the surgical bleeding alarm result is output.

[0030] A patient bleeding monitoring module, configured to real-time detect the blood aspiration volume of the patient to be measured, judge whether an alarm is needed based on the blood aspiration volume, and if so, output the surgical bleeding alarm result.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. Select the suction tube and suction head for liquid shunt suction during this operation of the patient to be tested based on the basic information of the patient to be tested and the operation-related information. Install and set up the suction tube and suction head, and verify the device seal.

[0033] 2. When receiving the result of completed preoperative preparation, perform the surgical operation. Create a digital twin of the tissue structure based on the body tissue structure of the patient to be tested in the surgical field to assist subsequent liquid shunt suction monitoring based on the surgical process.

According to the operation-related information of the patient to be tested and the regional division result, use the digital twin of the tissue structure to simulate the liquid flow situation during the operation of the patient to be tested to obtain the predicted liquid flow path information. Judge whether barrier intervention is required according to the predicted liquid flow path information. If so, perform barrier intervention to prevent the blood in the liquid generated during the operation from mixing with other liquids, facilitating the accuracy of liquid shunt suction differentiation, and further improving the surgical safety of liquid shunt suction for the patient to be tested during the operation;

[0034] 3.

[0038] The following further elaborates on this application in conjunction with the accompanying drawings.

[0039] The embodiment of this application discloses a liquid shunt suction monitoring method based on the surgical process.

[0040] A liquid shunt suction monitoring method based on the surgical process includes:

[0041] Referring to Figure 1 , step S1, select a suction tube and a suction head according to the basic information of the patient to be tested and the surgical relevant information, install the suction tube and the suction head, and verify the device sealing performance after installation. If the sealing performance is good, output the result of completed preoperative preparation. Step S1 specifically includes:

[0042] Obtain the basic information of the patient to be tested and the surgical relevant information, where the surgical relevant information includes surgical type information, surgical scale information, and surgical wound site information.

[0043] Judge the type of liquid generated by the patient to be tested during the surgical process according to the surgical type information of the patient to be tested to obtain the predicted liquid generation type information, and determine the suction tube type information and the suction head type information according to the predicted liquid generation type information.

[0044] If the predicted liquid generation type information includes blood type and other liquid types, the suction tube type information is multiple suction tubes, and each suction tube corresponds to a different type of liquid. If the predicted liquid generation type information only includes blood type or only includes other liquid types, the suction tube type information is a single type of suction tube. If the predicted liquid generation type information includes blood type and other liquid types, the suction head type information is multiple suction heads, and each suction head corresponds to a different type of liquid. If the predicted liquid generation type information only includes blood type or only includes other liquid types, the suction head type information is a single type of suction head. Among them, the suction tube and the suction head for sucking the same type of liquid correspond to each other one by one.

[0045] Mark the classifications of different types of suction tubes based on the suction tube type information, and mark the classifications of different types of suction heads based on the suction head type information. For example, if a suction tube used for sucking blood is marked red, then the corresponding suction tube for sucking blood is marked red; if a suction tube used for sucking other types of liquids is marked blue, then the corresponding suction tube for sucking other types of liquids is marked blue.

[0046] Step S1 further includes:

[0047] According to the surgical type information and surgical wound site information of the patient to be tested, preset the liquid generation amount during the operation of the patient to be tested to obtain the predicted liquid generation amount, and determine the suction tube size and suction head size based on the liquid generation amount. Among them, the larger the predicted liquid generation amount, the larger the suction tube size and the larger the suction head size.

[0048] Based on the suction tube size, suction head size, suction tube type information, and suction head type information, select the suction tube and suction head for sucking the liquid generated by the patient to be tested during the operation to obtain the selected result of the suction assembly.

[0049] Based on the selected result of the suction assembly, install the suction tube and suction head on the negative pressure suction source respectively. The negative pressure suction source, suction tube, suction head, and suction bottle are combined to form a negative pressure shunt suction device.

[0050] Among them, the suction bottle corresponds to the suction tube and the suction head. If the predicted liquid generation type information includes the blood type and other liquid types, multiple suction bottles are correspondingly set to collect different types of liquids generated by the patient to be tested during the operation. If the predicted liquid generation type information only includes the blood type or only includes other liquid types, and the suction tube type information is a single type of suction tube, then a single type of suction bottle is correspondingly set to collect a single type of liquid generated by the patient to be tested during the operation.

[0051] After the installation is completed, verify the sealing performance of the negative pressure shunt suction device. If the sealing performance is good, output the result of the preoperative preparation completion. If the sealing performance is poor, adjust the negative pressure shunt suction device until the sealing performance is good, and output the result of the preoperative preparation completion.

[0052] Refer to Figure 1 , Step S2, when receiving the result of the preoperative preparation completion, perform the surgical operation, create a digital twin of the tissue structure based on the body tissue structure of the patient to be tested in the surgical field, and obtain the regional division result by dividing the surgical field of the patient to be tested according to the digital twin of the tissue structure. Step S2 specifically includes:

[0053] When receiving the result of the preoperative preparation completion, perform the surgical operation, and take pictures of the surgical process of the patient to be tested based on the surgical field camera to obtain the surgical field shooting information.

[0054] Detect the undulating height of the organizational structure of the patient to be measured in the intraoperative field-of-view shooting information to obtain the organizational structure height information.

[0055] Create a digital twin of the organizational structure of the patient to be measured based on the intraoperative field-of-view shooting information and the organizational structure height information.

[0056] Based on the digital twin of the organizational structure of the patient to be measured and the information of the surgical wound site, select the wound site of the patient to be measured in the intraoperative field-of-view shooting image and mark it as the wound area.

[0057] Based on the digital twin of the organizational structure, determine the area with a lower structural composition in the intraoperative field of view of the patient to be measured to obtain the low intraoperative field area.

[0058] Mark the weak part of the tissue of the patient to be measured in the intraoperative field-of-view shooting information as the weak area.

[0059] For example: The circular area that spreads from the wound area to the surrounding is the weak area. The spread size of the circular area depends on the wound size and wound depth of the wound area. The larger the wound size, the larger the spread of the circular area, and the deeper the wound depth, the larger the spread of the circular area. The area where blood vessels converge and are prone to skin breakage is marked as the weak area.

[0060] Mark the part of the intraoperative field-of-view shooting information except the wound area, the low intraoperative field area, and the weak area as the lightly related area. The wound area, the low intraoperative field area, the weak area, and the lightly related area are combined to form the area division result.

[0061] Refer to Figure 1 , step S3, based on the surgical-related information and the area division result, simulate the liquid flow situation generated during the surgery in the digital twin of the organizational structure to obtain the predicted liquid flow path information, and judge whether barrier intervention is required based on the predicted liquid flow path. If so, perform the barrier intervention operation. Step S3 specifically includes:

[0062] Judge whether there is liquid generated by the patient to be measured in the intraoperative field-of-view shooting information of the patient to be measured. If so, output the result of self-interference and mark the part where the patient generates liquid to obtain the self-generated liquid part information. If not, output the result of no self-interference.

[0063] For example: During a dental surgery, the salivary glands in the human oral cavity secrete saliva, which interferes with the suction accuracy of the liquid in the oral cavity of the patient to be measured.

[0064] When different types of liquids are generated during the operation of the patient to be tested, the surgical wound site information and the self-generated liquid site information of the patient to be tested are marked as the liquid generation sources of the patient to be tested. Based on the lower position area of the surgical field and the liquid generation sources, the liquid flow situation generated by the patient to be tested during the operation is simulated on the digital twin of the tissue structure to obtain the first predicted liquid flow path information. Based on the first predicted liquid flow path information, it is judged whether the blood type and other liquid types are fused. If they are not fused, a negative result of barrier intervention is output. If the blood type and other liquid types are fused, a positive result of barrier intervention is output.

[0065] After receiving the positive result of barrier intervention, according to the surgical wound site information, the self-generated liquid site information and the lower position area of the surgical field of the patient to be tested, the position for blocking the blood type and other liquid types during the operation of the patient to be tested is judged to obtain the barrier intervention position information, and the barrier is carried out on the tissue structure of the patient to be tested based on the barrier intervention position information.

[0066] Specifically, the barrier intervention position information needs to satisfy that after the barrier intervention, the blood type and other liquid types flow based on different liquid flow paths.

[0067] Refer to Figure 1 , step S4, the liquid types generated during the operation are identified in real time to obtain the real-time liquid generation type information. According to the real-time liquid generation type information and the digital twin of the tissue structure, the suction path is planned to obtain the liquid suction path information. The residence time of the suction head at each position in the liquid suction path information is judged to obtain the path node suction duration information. Step S4 specifically includes:

[0068] Based on the optical sensor, the liquid types generated by the patient to be tested during the operation are detected in real time to obtain the real-time liquid generation type information, and the real-time liquid generation type information includes the blood type and / or other liquid types.

[0069] After the barrier intervention, based on the lower position area of the surgical field, the liquid generation sources and the barrier intervention position information, the liquid flow situation in the body of the patient to be tested is simulated on the digital twin of the tissue structure to obtain the second predicted liquid flow path information, and the second predicted liquid flow path information is adjusted and updated in real time based on the real-time liquid generation type information.

[0070] Based on the second predicted liquid flow path information, the suction path of the suction head in the negative pressure shunt suction device is planned to obtain the liquid suction path information.

[0071] Specifically, the liquid suction path information is the reverse path of the second predicted liquid flow path information.

[0072] Based on the regional division result and the organizational structure height information, determine the suction residence time of the suction head at each position in the liquid suction path information to obtain the path node suction time information.

[0073] Specifically, if the wound area is passed through in the liquid suction path, determine the suction residence time of the suction head passing through the wound area according to the wound size, wound depth, and wound liquid production amount of the wound area. Among them, the suction residence time of the wound area is positively correlated with the wound liquid production amount, negatively correlated with the wound size, and negatively correlated with the wound depth.

[0074] Refer to Figure 1 , step S5, determine the suction negative pressure and suction frequency according to the basic information of the patient to be measured and the surgical relevant information. Based on the liquid suction path information, path node suction time information, suction negative pressure, and suction frequency, perform shunt suction on the liquid generated during the operation. During the operation, adjust the suction negative pressure in real time according to the impurities and liquid viscosity in the suction liquid, and adjust the suction frequency in real time according to the liquid generation situation during the operation. Step S5 specifically includes:

[0075] Determine the suction negative pressure according to the basic information of the patient to be measured. The basic information of the patient to be measured includes the patient's age information, patient's physical condition information, and patient's medical history information. Determine the suction frequency according to the surgical relevant information of the patient to be measured.

[0076] An example is given for illustration: preset the suction negative pressure based on the patient's age information, patient's physical condition information, and patient's medical history information. Among them, the greater the patient's age information, the smaller the suction negative pressure; the worse the patient's physical condition information, the smaller the suction negative pressure; the more severe the historical illness of the patient to be measured in the patient's medical history information, the smaller the suction negative pressure. Preset the suction frequency of the patient to be measured according to the predicted liquid generation amount of the patient to be measured. Among them, the greater the predicted liquid generation amount of the patient to be measured, the higher the suction frequency of the patient to be measured.

[0077] Perform shunt suction on the liquid generated during the operation based on the liquid suction path information, path node suction time information, suction negative pressure, and suction frequency. During the operation, make a primary adjustment to the suction negative pressure according to the liquid viscosity.

[0078] In specific applications, match the liquid viscosity with the liquid viscosity threshold suitable for the suction head. If the liquid viscosity is greater than the liquid viscosity threshold, increase the suction negative pressure.

[0079] Make a secondary adjustment to the suction negative pressure according to the impurities in the suction liquid.

[0080] In specific applications, when the suction head attracts impurities, it is determined whether to increase the suction negative pressure according to the size of the impurities. When the size of the impurities is greater than the preset impurity size threshold, the suction negative pressure is increased, and the difference between the impurity size and the preset impurity size threshold is calculated. Among them, the degree of increase in the suction negative pressure is positively correlated with the difference in impurity size.

[0081] During the operation, the liquid generation situation is detected in real time to obtain liquid generation parameter information, where the liquid generation parameter information includes the liquid generation volume and the liquid generation speed. Based on the liquid generation volume and the liquid generation speed, the suction frequency during the operation of the preset patient to be measured is adjusted in real time.

[0082] Refer to Figure 1 , step S6, during the operation, the blood suction volume of the patient to be measured is detected in real time. Based on the basic information of the patient to be measured, the bleeding volume threshold is preset, and the blood suction volume is compared with the bleeding volume threshold to determine whether to give an alarm. If necessary, the surgical bleeding alarm result is output. Step S6 specifically includes:

[0083] Determine the bleeding volume threshold of the patient to be measured according to the basic information of the patient to be measured.

[0084] For example: Based on the patient's age information, the patient's physical condition information, and the patient's medical history information, the bleeding volume threshold of the patient to be measured is preset. Among them, the larger the patient's age information, the smaller the bleeding volume threshold; the worse the patient's physical condition information, the smaller the bleeding volume threshold; and the more serious the historical illness of the patient to be measured in the patient's medical history information, the smaller the bleeding volume threshold.

[0085] Based on the optical sensor, the liquid level height of the attracted blood during the operation of the patient to be measured is detected to obtain blood attraction height information. Based on the blood attraction height information, the blood suction volume is calculated, and the blood suction volume is compared with the bleeding volume threshold to determine whether to give an alarm. If necessary, the surgical bleeding alarm result is output.

[0086] Based on the wireless transmission module, the surgical bleeding alarm result is transmitted to the display screen for display.

[0087] The embodiment of the present application also discloses a liquid shunt suction monitoring system based on the operation process.

[0088] Refer to Figure 2 , a liquid shunt suction monitoring system based on the operation process, including:

[0089] A preoperative preparation module, configured to select a suction tube and a suction head according to the basic information of the patient to be measured and the operation-related information, install the suction tube and the suction head, and verify the device sealing performance after the installation is completed. If the sealing performance is good, the preoperative preparation completion result is output.

[0090] The region division module is configured to perform surgical operations after receiving the result of preoperative preparation completion, create a digital twin of the organizational structure based on the body organizational structure of the patient to be measured in the surgical field, and divide the surgical field of the patient to be measured according to the digital twin of the organizational structure to obtain a region division result.

[0091] The barrier intervention judgment module is configured to, based on the surgical-related information and the region division result, simulate the liquid flow situation generated during the surgical process in the digital twin of the organizational structure to obtain predicted liquid flow path information, and judge whether barrier intervention is required based on the predicted liquid flow path. If so, perform barrier intervention operations.

[0092] The suction parameter judgment module is configured to identify the type of liquid generated during the surgical process in real time to obtain real-time liquid generation type information, plan the suction path according to the real-time liquid generation type information and the digital twin of the organizational structure to obtain liquid suction path information, and judge the residence time of the suction head at each position in the liquid suction path information to obtain path node suction duration information.

[0093] The shunt suction operation module is configured to determine the suction negative pressure and suction frequency according to the basic information of the patient to be measured and the surgical-related information, perform shunt suction on the liquid generated during the surgical process based on the liquid suction path information, path node suction duration information, suction negative pressure, and suction frequency, adjust the suction negative pressure in real time according to the impurities and liquid viscosity in the suction liquid during the surgical process, and adjust the suction frequency in real time according to the liquid generation situation during the surgical process.

[0094] The patient bleeding monitoring module is configured to, during the surgical process, detect the blood suction volume of the patient to be measured in real time, preset the bleeding volume threshold based on the basic information of the patient to be measured, compare the blood suction volume with the bleeding volume threshold to judge whether an alarm is required, and if so, output a surgical bleeding alarm result.

[0095] The implementation principle of a liquid diversion and suction monitoring system based on the surgical process in an embodiment of this application is as follows: According to the basic information of the patient to be measured and the surgical-related information, select the suction tube and suction head for liquid diversion and suction in this operation of the patient to be measured. Install and set the suction tube and suction head, and verify the device's sealing performance. If the device has good sealing performance, output the result of preoperative preparation completion, indicating that the liquid diversion and suction will not reduce the accuracy of liquid diversion and suction due to sealing, thereby improving the accuracy of liquid diversion and suction monitoring based on the surgical process. When the result of preoperative preparation completion is received, perform surgical operations. Create an organizational structure digital twin based on the body tissue structure of the patient to be measured in the surgical field to assist subsequent liquid diversion and suction monitoring based on the surgical process. Divide the surgical field based on the organizational structure digital twin to obtain the regional division result. According to the surgical-related information of the patient to be measured and the regional division result, use the organizational structure digital twin to simulate the liquid flow situation during the surgical process of the patient to be measured to obtain predicted liquid flow path information.
