[0028] The human abdominal region contains many organs, and the related diseases of these organs have received much attention. In order to improve the success rate of surgeries on the organs in the abdominal region, some current medical software can interact with doctors to achieve surgical planning for organ resection. During the surgical planning process, the situations of different patients are different, and the information that doctors need to know is also different. It is necessary to provide doctors with as rich surgical planning results as possible. Currently, doctors can only estimate surgical parameters based on surgical experience, but this method lacks accuracy and is extremely likely to cause some medical risks.

[0029] In view of this, the present application proposes an abdominal surgical planning system and an electronic device; among them, the abdominal surgical planning system includes: a data input module for obtaining a three-dimensional model of a target organ of a patient; a display module for displaying the three-dimensional model; a processing module for calculating parameters of the target organ according to a default calculation formula; the parameters of the target organ are used for risk assessment of surgical planning operations, and / or for determining surgical prompt information for performing a cutting operation on the target organ of the patient; in the case where the default calculation formula does not meet the conditions, the data input module obtains a configuration operation of the calculation formula by the user to obtain a target calculation formula; the processing module calculates the parameters of the target organ according to the target calculation formula; it is possible to configure the parameter calculation formula of the organ for special patients, which helps to improve the accuracy of patient parameter calculation, and then better guide the abdominal surgery and reduce medical risks.

[0030] In order to illustrate the technical solution of the present application, it will be described below through specific embodiments.

[0031] Please refer to Figure 1 , Figure 1 which shows a schematic structural diagram of an abdominal surgical planning system 100 provided by an embodiment of the present application. The above-mentioned abdominal surgical planning system 100 may be a software system implemented by a computer program running on an electronic device, or a hardware system composed of physical components, or a software and hardware system formed by a combination of a computer application program and physical components. The present application does not make any restrictions on this. The above-mentioned electronic device may be a computer, a smart phone, a medical device dedicated to surgical planning, or other intelligent devices. The present application does not make any restrictions on this.

[0032] Specifically, the above-mentioned abdominal surgical planning system may include: a data input module 101, a display module 102, and a processing module 103.

[0033] The data input module 101 can be used to obtain a three-dimensional model of a target organ of a patient.

[0034] Among them, the target organ may refer to an organ in the human abdominal region, including but not limited to the liver, intestine, pancreas, and spleen.

[0035] In an embodiment of the present application, the data input module 101 can perform three-dimensional reconstruction based on the patient's Computed Tomography (CT) data, Magnetic Resonance (MR) data, or other medical data. These medical data can be Digital Imaging and Communications in Medicine (DICOM) data in the standard format of Data Conservation Format (dcm). Among them, the three-dimensional reconstruction can include sequence loading and automatic tissue segmentation. Sequence loading refers to loading the above-mentioned medical data into software, and the software transforms the loaded medical data into continuous and operable two-dimensional images according to specific rules. Automatic tissue segmentation means that the software extracts specific tissue data in the two-dimensional image, marks the data in the two-dimensional image, and at the same time performs three-dimensional modeling on the specific tissue data, generates a three-dimensional mesh, and performs visual output, so that the user can intuitively and accurately view the three-dimensional model. The three-dimensional model of the target organ can be used to simulate the cutting surgery of the target organ and perform surgical planning operations. In other embodiments, the data input module 101 can also read the three-dimensional model of the target organ stored in the memory or transmitted by an external device. The present application does not limit the manner in which the data input module 101 obtains the three-dimensional model.

[0036] The display module 102 can be used to display the three-dimensional model.

[0037] In an embodiment of the present application, the display module 102 can display the three-dimensional model of the target organ for the doctor to perform surgical planning operations. Among them, the display module 102 can refer to the display of the abdominal surgical planning system 100.

[0038] The processing module 103 can be used to calculate the parameters of the target organ according to the default calculation formula.

[0039] In an embodiment of the present application, the abdominal surgical planning system can be preset with a default calculation formula, which can be used to calculate the parameters of the target organ. Specifically, the processing module 103 can obtain the patient information of the patient, input the patient information into the default calculation formula, and obtain the parameters of the target organ. Among them, the patient information can include but is not limited to the patient's height, weight, and age.

[0040] Among them, the parameters of the target organ can be used for risk assessment of surgical planning operations and / or for determining surgical prompt information for performing a cutting operation on the target organ of the patient. In some embodiments of the present application, the target organ is the liver, and the parameters of the target organ may include, but are not limited to, the body surface area (BSA) of the liver, the standardized liver volume, and the ratio of the remaining liver weight.

[0041] In some embodiments of the present application, the parameters of the target organ can be displayed through the display module 102. The risk assessment result and / or surgical prompt information of the surgical planning operation obtained based on the parameters of the target organ can also be displayed through the display module 102, so that the abdominal surgical planning system can intuitively display the information related to the surgical planning operation of the target organ cutting operation to better guide the abdominal surgery.

[0042] In an embodiment of the present application, when the default calculation formula does not meet the conditions, the data input module 101 can obtain the user's configuration operation on the calculation formula to obtain the target calculation formula. The processing module 103 can calculate the parameters of the target organ according to the target calculation formula.

[0043] In an embodiment of the present application, for some special patients, the default calculation formula does not meet the conditions. Not meeting the conditions means that the default calculation formula is not applicable to the patient, that is, after inputting the patient information of the patient into the default calculation formula, the error between the parameters of the target organ obtained and the actual situation of the patient exceeds the acceptable range. Specifically, the processing module 103 can determine whether the default calculation formula meets the conditions based on the patient information of the patient, or it can be directly confirmed that the default calculation formula does not meet the conditions when the data input module 101 receives the configuration operation.

[0044] If the default calculation formula meets the conditions, it means that the calculation result obtained by the processing module 103 according to the default calculation formula is reliable. At this time, the parameters of the target organ obtained according to the default calculation formula can be directly used. If the default calculation formula does not meet the conditions, it means that the calculation result obtained by the processing module 103 according to the default calculation formula is unreliable. At this time, the data input module 101 can obtain the target calculation formula according to the user's configuration operation on the calculation formula, and the processing module 103 can calculate the parameters of the target organ according to the target calculation formula to obtain the parameters of the target organ to replace the calculation result of the default calculation formula.

[0045] In an embodiment of the present application, while displaying a three-dimensional model of a patient's target organ, parameter calculation of the target organ is performed according to a default calculation formula, and when the default calculation formula does not meet the conditions, a target calculation formula is obtained according to the user's configuration operation on the calculation formula, so as to perform parameter calculation on the target organ according to the target calculation formula. It is possible to configure a parameter calculation formula for special patients, which helps to improve the accuracy of patient parameter calculation. The calculated parameters are used for risk assessment of surgical planning operations and / or for determining surgical prompt information for performing a cutting operation on the target organ of the patient, which can better guide abdominal surgery and reduce medical risks.

[0046] In an embodiment of the present application, for the parameters of each target organ, the abdominal surgery planning system 100 may store one or more pre-designed calculation formulas and preset a default calculation formula in the stored pre-designed calculation formulas.

[0047] In some embodiments of the present application, when the target organ is the liver, the parameters of the target organ may include one or more of the liver body surface area, standardized liver volume, and residual liver weight ratio. Please refer to Figures 2 to 4 , Figures 2 to 4 which shows software interfaces respectively for configuring the liver body surface area, standardized liver volume, and residual liver weight ratio displayed by the display module 102.

[0048] Figure 2 In, the pre-designed calculation formula and the default calculation formula for the liver body surface area are both: (height*weight / 3600)^(1 / 2), where height represents height and weight represents weight.

[0049] Figure 3 In, the pre-designed calculation formula for the standardized liver volume includes: 706.2*(height*weight / 3600)^(1 / 2)+2.4 and -794.42+(1267.25*BSA), where 706.2*(height*weight / 3600)^(1 / 2)+2.4 is the default calculation formula, and BSA represents the liver body surface area.

[0050] Figure 4 In, the pre-designed calculation formula for the residual liver weight ratio includes: RLV / weight and (RLV*0.95) / (weight*10), where RLV / weight is the default calculation formula, and RLV represents the residual liver volume.

[0051] It can be understood that Figures 2 to 4The various pre-designed calculation formulas are only examples. In actual applications, the formula content of the pre-designed calculation formulas, the number of pre-designed calculation formulas, and the default calculation formula selected in the pre-designed calculation formulas can all be adjusted according to actual needs. And, Figures 2 to 4 To illustrate the case where the target organ is the liver, the implementation methods for organs in other abdominal regions are similar to those of the liver, and this application will not elaborate on them.

[0052] This application provides different determination methods for whether the default calculation formula meets the conditions.

[0053] In some embodiments of this application, the abdominal surgery planning system 100 may further include: The processing module 103 obtains the case information of the patient. Among them, the case information records the patient's historical diseases and the surgeries that have been performed. If the historical disease is a disease of a preset type, or the surgery that has been performed includes the resection of the target organ, it is confirmed that the default calculation formula does not match the patient.

[0054] Among them, the disease of the preset type is a disease that causes a volume change of the target organ. When the target organ is the liver, the diseases of the preset type include but are not limited to fatty liver, cirrhosis, and metabolic diseases.

[0055] The default calculation formula is generally applicable to patients with normal target organ morphology. Since diseases of the preset type cause changes in the liver volume, for example, fatty liver and cirrhosis will cause the liver to become significantly larger, and the target organ morphology of patients who have undergone the resection of the target organ is specific. At this time, it can be confirmed that the default calculation formula does not meet the conditions, so that the user can configure the target calculation formula applicable to this patient.

[0056] In some other embodiments of this application, the abdominal surgery planning system 100 may further include: The processing module 103 obtains the parameter theoretical range of the patient. After inputting the patient information into the default calculation formula, if the parameter of the target organ obtained exceeds the parameter theoretical range, it is confirmed that the default calculation formula does not meet the conditions.

[0057] In other embodiments, the abdominal surgery planning system 100 may also confirm that the default calculation formula does not meet the conditions when the data input module 101 receives a configuration operation.

[0058] When the default calculation formula does not meet the conditions, the display module 102 may output a prompt message to prompt the user to configure the calculation formula.

[0059] This application does not limit the configuration process of the calculation formula.

[0060] In some embodiments of the present application, the data input module 101 obtains the user's configuration operation on the calculation formula, and obtaining the target calculation formula may include: according to the selection operation among multiple pre-designed calculation formulas, using the selected pre-designed calculation formula as the target calculation formula.

[0061] For example, in Figure 3 , the pre-designed calculation formulas include: RLV / weight and (RLV*0.95) / (weight*10), and RLV / weight is the default calculation formula. At this time, the user can click the control 31 "Set as Default" to trigger the selection operation, set (RLV*0.95) / (weight*10) as the default, so as to use the selected pre-designed calculation formula (RLV*0.95) / (weight*10) as the target calculation formula.

[0062] In some other embodiments of the present application, the data input module 101 obtains the user's configuration operation on the calculation formula, and obtaining the target calculation formula may include: according to the user's input operation, using the input calculation formula as the target calculation formula.

[0063] For example, in Figure 3 , the user can click the control 32 "+" to control the display module 102 to pop up an input box. In response to the input operation triggered by the user in the input box, use the calculation formula input by the user as the target calculation formula.

[0064] For the input calculation formula, in order to avoid formula errors, in some embodiments of the present application, the data input module 101 using the input calculation formula as the target calculation formula according to the user's input operation may include: according to the input operation, obtaining the input calculation formula, performing a verification operation on the input calculation formula, and after the verification operation passes, using the input calculation formula as the target calculation formula.

[0065] Among them, the verification operation may include a formula legality verification operation and / or a formula result reliability verification operation. The formula legality verification operation is used to verify whether the characters in the input calculation formula are legal. The formula result reliability verification operation is used to verify whether the input calculation formula can output a valid result.

[0066] Specifically, the calculation formula input by the user generally consists of four parts: numbers, operation symbols, keywords, and sequence symbols (parentheses, square brackets, etc.). For example, in the input calculation formula (height*weight / 3500)^(1 / 2), "height" and "weight" represent keywords, "3500", "1", and "2" are numbers, "*", " / ", and "^" are operation symbols, and "(", ")" are sequence symbols.

[0067] In some embodiments of the present application, the electronic device may replace the keywords in the target calculation formula with specific values. For example, both height and weight in (height * weight / 3500) ^ (1 / 2) are replaced with 1 to obtain the formula to be tested. At this time, the formula to be tested only contains numbers, arithmetic symbols, and sequence symbols. Then, a formula legality verification operation can be performed to verify whether the characters in the input calculation formula are legal.

[0068] The formula legality verification operation may include at least one of the following:

[0069] 1. Detect whether there are abnormal symbols in the input calculation formula, such as whether there are other symbols in the input calculation formula except numbers, arithmetic symbols, and sequence symbols;

[0070] 2. Detect whether there are arithmetic symbols in abnormal positions in the input calculation formula. For example, in the input calculation formula, the arithmetic symbol is at the beginning or end;

[0071] 3. Detect whether there are abnormalities in the adjacent symbols of each symbol in the input calculation formula. For example, there are multiple consecutive arithmetic symbols in the input calculation formula;

[0072] 4. Detect whether there are abnormalities in the sequence symbols in the input calculation formula. For example, a number appears in front of the left parenthesis, a number appears behind the right parenthesis, or the parenthesis sequence is incorrect;

[0073] 5. Detect whether there are abnormalities in the scientific operators in the input calculation formula. For example, a number appears in front of the scientific operator.

[0074] If there are abnormal symbols, arithmetic symbols in abnormal positions, abnormal adjacent symbols, abnormal sequence symbols, or abnormal scientific operators in the input calculation formula, the formula legality verification fails. At this time, the display module 102 can output a prompt message to prompt the user to re-configure the calculation formula.

[0075] If there are no abnormal symbols, arithmetic symbols in abnormal positions, abnormal adjacent symbols, abnormal sequence symbols, and no abnormal scientific operators in the input calculation formula, the formula legality verification passes.

[0076] In some embodiments of the present application, the formula result reliability verification operation may include: inputting the sample parameters of the sample patient into the input calculation formula to obtain the parameter to be verified of the target organ of the sample patient. Comparing the parameter to be verified with the standard parameter of the target organ of the sample patient to obtain the verification result.

[0077] Taking the input calculation formula (height * weight / 3500) ^ (1 / 2) as an example, the electronic device can input the sample parameters (such as: height: 160 cm, weight: 50 kg) into the input calculation formula to obtain the parameter to be verified of the target organ of the sample patient (i.e., the calculation result). The verification result will be obtained by comparing the parameter to be verified with the standard parameter of the target organ of the sample patient. If there is no parameter to be verified, that is, a normal result cannot be output, the parameter to be verified is out of the normal range, for example, the parameter to be verified is negative, or the error between the parameter to be verified and the standard parameter exceeds the first error range, then the reliability verification of the formula result fails. Otherwise, it can be confirmed that the reliability verification of the formula result is successful.

[0078] For the case where the error between the parameter to be verified and the standard parameter exceeds the first error range, considering the particularity of the patient himself, a prompt message can be output to prompt the user that there is a certain error in the result. In response to receiving the user's confirmation information about the error, it can be confirmed that the reliability verification of the formula result is successful.

[0079] After the verification passes, the processing module 103 can calculate the parameters of the target organ of the patient according to the target calculation formula.

[0080] In some embodiments of the present application, the processing module 103 can obtain the patient information and calculate the parameters of the target organ of the patient according to the patient information.

[0081] Among them, the patient information includes the data of the keywords in the target calculation formula, such as height and weight. The patient information can be input by the user, obtained through the label (tag) carried by the foregoing medical image, or obtained from the three-dimensional model of the foregoing target organ, and the present application does not make any restrictions on this.

[0082] In order to further improve the accuracy of parameter calculation, the processing module 103 can verify the patient information. If the patient information is incorrect, a prompt message can be output to prompt the user to re-confirm the input patient information.

[0083] Please refer to Figure 5 , Figure 5The specific process of calculating the liver parameters of a patient is shown. When the default calculation formula does not meet the conditions, in response to receiving an input operation triggered by the user, the electronic device can use the formula input by the user as the target calculation formula and perform formula legality verification operations and formula result reliability verification operations. If the formula legality verification fails or the formula result reliability verification fails, a prompt message is output to prompt the user that the formula is incorrect. If both the formula legality verification and the formula result reliability verification pass, the formula is stored, and parameter calculation is performed on the target organ based on the patient information. When the calculation fails, a prompt message is output to prompt the user that the calculation fails. When the calculation is successful, the parameters of the target organ can be obtained.

[0084] In an embodiment of the present application, the parameters of the above target organ can be used to guide the surgical planning operation of the resection surgery of the target organ.

[0085] Specifically, in some embodiments of the present application, the above target organ can be the liver, and the parameters of the target organ are liver parameters. The liver parameters can be used to guide liver cutting. The data input module 101 can interact with the user to receive the user's liver editing operation, and implement liver segmentation, free segmentation, and / or watershed segmentation to plan the remaining liver and the resected liver.

[0086] Specifically, liver cutting can include hepatic segment segmentation, free segmentation, and watershed segmentation. Hepatic segment segmentation is used to divide the liver into eight intestinal segments according to the vascular directions of the arteries, portal veins, and hepatic veins inside the liver. Hepatic segment segmentation can help surgeons plan the surgical path during liver resection. Free segmentation is used to plan the surgical path for cutting the diseased part on the three-dimensional model according to the position of the diseased part inside the liver, and can be used to adjust the cutting surface according to the adjustment data triggered by the user, so as to retain healthy tissue to the greatest extent and completely resect the lesion. Watershed segmentation is used to calculate the area through which blood flows according to the blood vessels and mark the liver within the area through which blood flows to help the user plan the optimal surgical path, maximize the retention of healthy liver tissue, and ensure complete resection of the diseased part. The surgical planning operation is used to plan the cutting path on the three-dimensional liver model.

[0087] In some embodiments of the present application, the target organ is the liver, and the parameter of the target organ is the ratio of the remaining liver weight. The abdominal surgical planning system 100 may further include: the processing module 103 determines the risk assessment information of the surgical planning operation according to the comparison result between the ratio of the remaining liver weight and a preset ratio threshold.

[0088] Among them, the proportion threshold can be set according to the actual situation. In some embodiments of the present application, the proportion threshold can be 40%. When the ratio of the remaining liver weight to the total body weight is greater than or equal to the proportion threshold, it indicates that the remaining liver can survive and regenerate normally, and the surgical planning operation is reliable. At this time, risk assessment information with a lower risk can be determined for display by the display module 102. When the ratio of the remaining liver weight to the total body weight is less than the proportion threshold, it indicates that the remaining liver is difficult to survive and regenerate normally, and the surgical planning operation is unreliable. At this time, risk assessment information with a higher risk can be determined for display by the display module 102.

[0089] In some other embodiments of the present application, the target organ is the liver, and the parameter of the target organ is the liver body surface area. The abdominal surgical planning system 100 may further include: the processing module 103 determines prompt information on the drug dosage when cutting the patient's liver, determines prompt information on the liquid input volume when cutting the patient's liver, and / or determines prompt information on the patient's health status according to the liver body surface area.

[0090] Specifically, the drug dosage can be calculated based on the liver body surface area. For situations where it is necessary to input liquid to the user, the liquid input volume can also be calculated based on the liver body surface area. Moreover, the liver body surface area itself can indicate the overall health status of the patient to guide whether the patient is suitable for liver cutting.

[0091] In some other embodiments of the present application, the target organ is the liver, and the parameter of the target organ is the standardized liver volume. The abdominal surgical planning system 100 may further include: the processing module 103 determines prompt information on the cutting amount when cutting the patient's liver, determines prompt information on the patient's liver status, and / or determines the efficacy prediction information for cutting the patient's liver according to the standardized liver volume.

[0092] Specifically, the standardized liver volume can help doctors judge how much tissue can be safely removed during liver cutting. Moreover, the standardized liver volume is a sign of certain diseases, such as cirrhosis, fatty liver, hepatitis, etc., so it can be used to determine prompt information on the patient's liver status. During the treatment process, monitoring the standardized liver volume can help doctors predict the treatment effect of liver cutting.

[0093] In some other embodiments of the present application, the target organ is the liver, and the parameter of the target organ is the standardized liver volume. The abdominal surgical planning system 100 may further include: the processing module 103 corrects the absolute liver volume information of the patient according to the standardized liver volume.

[0094] Due to differences in height, weight, etc. among different individuals, the absolute liver volume may not be accurate enough, while the standardized liver volume can take these differences into account. When the standardized liver volume is used to correct the absolute liver volume information, the absolute liver volume information can be made more accurate.
