Anorectal manometry can examine the function and coordination of the internal and external sphincters, pelvic floor, and rectum, quantifying and assessing rectal and anal self-control and defecation function, and evaluating whether there are abnormalities in the physiological function of the rectum and anus.

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0056] Symptoms of anorectal dysfunction are characterized by fecal incontinence, constipation, and defecation disorders, affecting the quality of life of 1% to 5% of the population. Anorectal manometry can examine the function and coordination of the internal and external sphincters, pelvic floor, and rectum, quantifying and assessing rectal and anal self-control and defecation function, and evaluating whether there are abnormalities in the physiological function of the rectum and anus. Classic anorectal manometry uses 4-8 channels; the limited number of channels makes it difficult to detect minor lesions and local dynamic changes.

[0057] The application of high-resolution anorectal manometry technology has made up for the above-mentioned shortcomings and expanded its application, becoming an effective and powerful tool for anorectal surgeons. Locating the anatomical location of the anorectum helps to further calculate clinical parameters of anorectal manometry, and helps anorectal manometry analysts to quickly and effectively assess the physiological function of the rectum and anus.

[0058] Therefore, this application provides a corresponding anatomical location positioning scheme for anorectal manometry.

[0059] See Figure 1 As shown in the figure, this application discloses a method for anatomical location positioning of anorectal manometry, including:

[0060] Step S11: Determine the average pressure of each channel in the anorectal pressure cloud map within a preset time period.

[0061] Anorectal manometry involves inserting a water-irrigated or solid-state manometry catheter into the rectum and anus to measure rectal and anal pressure in real time, thereby obtaining an anorectal pressure contour map, for example. Figure 2 The diagram shows a specific anorectal manometry catheter. A balloon is positioned around the distal end of the catheter, and pressure sensors are located at positions P1 and P3. Pressure sensor P1 is used to acquire rectal pressure, and pressure sensor P3 is used to acquire anal pressure. The anorectal manometry catheter is inserted into the rectum and anus, and an anorectal pressure contour map is acquired in a resting state. For example… Figure 3 The diagram shows a specific anorectal pressure cloud map and Figure 4 The diagram shows another specific anorectal pressure cloud map. The colors represent pressure data values ​​and correspond to the color bars on the left. The horizontal axis represents time data, and the vertical axis represents anatomical location, i.e., the location of the anorectal manometry catheter. In the diagram, P4-P24 represent the pressure catheter serial numbers.

[0062] After obtaining the anorectal pressure cloud map, calculate the average pressure P_avgi (i=1,...,n1, where n1 is the number of channels) of each channel within a preset time period. The preset time period is, for example, from 21:00 to 21:10, or from 14:25 to 14:35. The appropriate preset time period can be selected according to the specific scenario.

[0063] Step S12: Locate the first peak channel and the second peak channel with the largest average pressure in each of the channels within the rectum and anus, respectively, and determine the pressure measurement anatomical positions corresponding to the first peak channel and the second peak channel as the rectal peak position and the anal peak position, respectively.

[0064] In this embodiment, the step of finding the first peak channel and the second peak channel with the largest average pressure in each of the channels within the rectum and anus includes: determining each first channel within the rectum and each second channel within the anus in each of the channels of the anorectal pressure cloud map according to the position of each pressure sensor in the anorectal manometry catheter; finding the first peak channel with the largest average pressure in each of the first channels, and finding the second peak channel with the largest average pressure in each of the second channels.

[0065] The rectal peak position is located at the position of the sensor (channel) with the highest average pressure in the balloon, and the anal peak position is located at the position of the sensor (channel) with the highest average pressure below the balloon. Therefore, based on the positions of each pressure sensor in the anorectal manometry catheter, each first channel in the rectal range and each second channel in the anal range are determined in each channel of the anorectal pressure cloud map. Then, the first peak channel with the highest average pressure is found in each first channel, and the second peak channel with the highest average pressure is found in each second channel. In this way, the anatomy of the pressure measurement corresponding to the first peak channel is the rectal peak position, and the anatomy of the pressure measurement corresponding to the second peak channel is the anal peak position.

[0066] Step S13: Interpolate the pressure values ​​of each channel to obtain interpolated pressure values.

[0067] In this embodiment, the step of interpolating the pressure values ​​of each of the channels to obtain interpolated pressure values ​​includes: determining the target accuracy corresponding to the anorectal pressure cloud map; obtaining estimated pressure values ​​based on the target accuracy and using the pressure values ​​of each of the channels; and inserting each estimated pressure value between two adjacent pressure values ​​to obtain interpolated pressure values.

[0068] Determine the required target accuracy, and interpolate the sensor pressure according to the target accuracy. That is, based on the target accuracy, obtain each estimated pressure value using the pressure value of each channel, and then insert each estimated pressure value between the corresponding two adjacent pressure values ​​to obtain each interpolated pressure value.

[0069] Furthermore, when interpolating the pressure values ​​of the channels, different interpolation methods can be used for the first and second channels. First, a first target accuracy corresponding to the rectal range in the anorectal pressure cloud map is determined. Based on this first target accuracy, and using the pressure values ​​of each of the first channels, first estimated pressure values ​​are obtained. Each first estimated pressure value is then inserted between two adjacent pressure values ​​to obtain the first interpolated pressure value In_Pij (i=1,2,...,n2, where n2 is the number of channels within the balloon after interpolation, and j is the corresponding time). Second, a second target accuracy corresponding to the anal range in the anorectal pressure cloud map is determined. Based on this second target accuracy, and using the pressure values ​​of each of the second channels, second estimated pressure values ​​are obtained. Each second estimated pressure value is then inserted between two adjacent pressure values ​​to obtain the second interpolated pressure value Out_Pij (i=1,2,...,n3, where n3 is the number of channels under the balloon after interpolation, and j is the corresponding time).

[0070] Step S14: Determine the rectal characteristic value within the rectal range and the anal characteristic value within the anal range based on the interpolated pressure value and the average pressure value; wherein, the characteristic value includes the interpolated average pressure value, peak ratio, minimum pressure ratio and pressure difference.

[0071] In this embodiment, determining the rectal characteristic values ​​within the rectal range based on the interpolated pressure values ​​and the average pressure values ​​includes: calculating the average rectal interpolated pressure value for each first channel, and determining the ratio between the average rectal interpolated pressure value and the average pressure value of the first peak channel as the rectal peak ratio; finding the first trough channel with the smallest average pressure value from each first channel, and determining the ratio between the average rectal interpolated pressure value and the average pressure value of the first trough channel as the rectal minimum pressure ratio, and determining the difference between the average rectal interpolated pressure value and the average pressure value of the first trough channel as the rectal pressure differential; obtaining rectal characteristic values ​​including the average rectal interpolated pressure value, the rectal peak ratio, the rectal minimum pressure ratio, and the rectal pressure differential. The specific process for determining the rectal characteristic values ​​within the rectal range is as follows:

[0072] 1.1) Calculate the average pressure of each interpolation channel, that is, calculate the average rectal interpolation pressure of each first channel, In_P_avgi (i=1,2,...,n2,n2 is the number of channels in the balloon after interpolation);

[0073] 1.2) Calculate the ratio of the average pressure of each interpolated channel to the average pressure of the peak channel. That is, the ratio between the average pressure after rectal interpolation and the average pressure of the first peak channel is determined as the rectal peak ratio In_p_ratio1i (i=1,2,....,n2,n2 is the number of channels in the balloon after interpolation);

[0074] 1.3) Calculate the ratio of the average pressure of each interpolation channel to the average pressure of the lowest pressure channel. That is, find the first valley channel with the smallest average pressure from each first channel, and determine the ratio between the average pressure of the rectal interpolation channel and the average pressure of the first valley channel as the rectal lowest pressure ratio In_P_ratio2i (i=1,2,....,n2,n2 is the number of channels in the balloon after interpolation);

[0075] 1.4) Calculate the difference between the average pressure of each interpolation channel and the average pressure of the lowest pressure channel. That is, the difference between the average pressure after rectal interpolation and the average pressure of the first valley channel is determined as the rectal pressure difference In_P_diffi (i=1,2,....,n2,n2 is the number of channels in the balloon after interpolation);

[0076] In this way, rectal characteristic values ​​are obtained, including the mean rectal pressure after rectal interpolation, the peak rectal pressure ratio, the lowest rectal pressure ratio, and the rectal pressure difference.

[0077] In this embodiment, determining the anal characteristic value within the anal range based on the interpolated pressure value and the average pressure value includes: calculating the average anal interpolated pressure value of the interpolated pressure value for each of the second channels; determining the ratio between the average anal interpolated pressure value and the average pressure value of the second peak channel as the anal peak ratio; searching upwards from the second peak channel for the first anal valley channel with the smallest average pressure value in each of the second channels, and determining the ratio and difference between the average anal interpolated pressure value and the average pressure value of the first anal valley channel as the first anal minimum pressure ratio and the first anal pressure difference, respectively; searching downwards from the second peak channel for the second anal valley channel with the smallest average pressure value in each of the second channels, and determining the ratio and difference between the average anal interpolated pressure value and the average pressure value of the second anal valley channel as the second anal minimum pressure ratio and the second anal pressure difference, respectively; and obtaining anal characteristic values ​​including the average anal interpolated pressure value, the anal peak ratio, the first anal minimum pressure ratio, the first anal pressure difference, the second anal minimum pressure ratio, and the second anal pressure difference. The process of determining the anal feature values ​​within the anal region is as follows:

[0078] 2.1) Calculate the average pressure of each interpolation channel, that is, calculate the average anal interpolation pressure of each second channel Out_P_avgi (i=1,2,...,n3,n3 is the number of channels below the balloon after interpolation);

[0079] 2.2) Calculate the ratio of the average pressure of each interpolated channel to the average pressure of the peak channel. That is, the ratio between the average pressure of the anal interpolation channel and the average pressure of the second peak channel is determined as the anal peak ratio Out_p_ratio1i (i=1,2,....,n3,n3 is the number of channels below the balloon after interpolation);

[0080] 2.3) Calculate the ratio of the average pressure of each interpolation channel to the average pressure of the lowest pressure channel above the peak channel. That is, in each second channel, starting from the second peak channel, find the first anal valley channel with the smallest average pressure. The ratio between the average pressure of the anal interpolation channel and the average pressure of the first anal valley channel is determined as the first anal minimum pressure ratio Out_p_ratio2i (i=1,2,....,n3,n3 is the number of channels below the balloon after interpolation).

[0081] 2.4) Calculate the difference between the average pressure of each interpolation channel and the average pressure of the lowest pressure channel above the peak channel. That is, the difference between the average pressure after anal interpolation and the average pressure of the first anal valley channel is determined as the first anal pressure difference Out_p_diff1i (i=1,2,....,n3,n3 is the number of channels below the balloon after interpolation).

[0082] 2.5) Calculate the ratio of the average pressure of each interpolation channel to the average pressure of the lowest pressure channel below the peak channel. That is, in each second channel, starting from the second peak channel, find the second anal valley channel with the smallest average pressure. The ratio between the average pressure of the anal interpolation channel and the average pressure of the second anal valley channel is determined as the second anal minimum pressure ratio Out_p_ratio3i (i=1,2,....,n3,n3 is the number of channels below the balloon after interpolation).

[0083] 2.6) Calculate the difference between the average pressure of each interpolated channel and the average pressure of the lowest pressure channel below the peak channel. That is, the difference between the average pressure after anal interpolation and the average pressure of the second anal valley channel is determined as the second anal pressure difference Out_p_diff2i (i=1,2,....,n3,n3 is the number of channels below the balloon after interpolation).

[0084] In this way, anal characteristic values ​​are obtained, including the anal interpolated mean pressure, anal peak ratio, first anal minimum pressure ratio, first anal pressure difference, second anal minimum pressure ratio, and second anal pressure difference.

[0085] Step S15: Determine the rectal edge channel and the anal edge channel from the anorectal pressure cloud map based on the rectal feature value and the anal feature value, respectively, and determine the corresponding pressure measurement anatomical positions of the rectal edge channel and the anal edge channel as the rectal edge position and the anal edge position, respectively.

[0086] In this embodiment, determining the rectal edge channel from the anorectal pressure cloud map based on the rectal feature value includes: inputting the rectal feature value into a target upper rectal edge detection model, so that the target upper rectal edge detection model uses the rectal feature value to detect each of the first channels upwards from the first peak channel in the anorectal pressure cloud map and outputs the upper rectal edge channel; and inputting the rectal feature value into a target lower rectal edge detection model, so that the target lower rectal edge detection model uses the rectal feature value to detect each of the first channels downwards from the first peak channel in the anorectal pressure cloud map and outputs the lower rectal edge channel.

[0087] For example Figure 5The diagram illustrates a specific method for obtaining the rectal edge location. Rectal feature values ​​are input into the target upper rectal edge detection model `rectum_mode1`. `rectum_mode1` uses these feature values ​​to detect each first channel upwards from the first peak channel in the anorectal pressure cloud map and outputs the upper rectal edge channel. Similarly, rectal feature values ​​are input into the target lower rectal edge detection model `rectum_mode2`. `rectum_mode2` uses these feature values ​​to detect each first channel downwards from the first peak channel in the anorectal pressure cloud map and outputs the lower rectal edge channel. The process of obtaining the target upper rectal edge detection model `rectum_mode1` involves: firstly, collecting a first training set, which includes historical anorectal pressure cloud maps and historical rectal feature values ​​with labeled upper rectal edge channels, to construct an initial upper rectal edge detection model. This initial model is then iteratively trained using the first training set until a target upper rectal edge detection model that meets the first preset convergence condition is obtained. Furthermore, the process of obtaining the target lower rectal edge detection model is as follows: First, a second training set is collected, which includes historical anorectal pressure cloud maps and historical rectal feature values ​​that have been labeled with the lower rectal edge channels. An initial lower rectal edge detection model is constructed, and the initial lower rectal edge detection model is iteratively trained using the second training set until a target lower rectal edge detection model that meets the second preset convergence condition is obtained. In a specific embodiment, the target upper rectal edge detection model and the target lower rectal edge detection model are the same model, that is, an initial rectal edge detection model is established, a first training set and a second training set are collected, and the initial rectal edge detection model is iteratively trained using the first training set and the second training set to obtain a target rectal edge detection model that meets the third preset convergence condition. The target rectal edge detection model can be used as either the target upper rectal edge detection model or the target lower rectal edge detection model.

[0088] In this embodiment, determining the anal edge channel from the anorectal pressure cloud map based on the anal feature value includes: inputting the anal feature value into a target anal upper edge detection model, so that the target anal upper edge detection model uses the anal feature value to detect each of the second channels upwards from the second peak channel in the anorectal pressure cloud map and outputs the anal upper edge channel; and inputting the anal feature value into a target anal lower edge detection model, so that the target anal lower edge detection model uses the anal feature value to detect each of the second channels downwards from the second peak channel in the anorectal pressure cloud map and outputs the anal lower edge channel.

[0089] For example Figure 6The diagram illustrates a specific method for obtaining the anal edge location. Anal feature values ​​are input into the target anal upper edge detection model `anal_mode1`, which uses these features to detect each second channel upwards from the second peak channel in the anorectal pressure cloud map and outputs the anal upper edge channel. Similarly, anal feature values ​​are input into the target anal lower edge detection model `anal_mode2`, which uses these features to detect each second channel downwards from the second peak channel in the anorectal pressure cloud map and outputs the anal lower edge channel. The specific process for obtaining the target anal upper edge detection model `anal_mode1` is as follows: First, a third training set is collected, which includes historical anorectal pressure cloud maps with annotated anal upper edge channels and historical anal feature values. An initial anal upper edge detection model is constructed using this third training set. The initial model is then iteratively trained using the third training set until a target anal upper edge detection model that meets the fourth preset convergence condition is obtained. Furthermore, the process of obtaining the target anal lower edge detection model is as follows: First, a fourth training set is collected, which includes historical anorectal pressure cloud maps and historical anal feature values ​​that have been labeled with the anal lower edge channel. An initial anal lower edge detection model is constructed, and the initial anal lower edge detection model is iteratively trained using the fourth training set until a target anal lower edge detection model that meets the fifth preset convergence condition is obtained. In a specific embodiment, the target anal upper edge detection model and the target anal lower edge detection model are the same model, that is, an initial anal edge detection model is established, a third training set and a fourth training set are collected, and the initial anal edge detection model is iteratively trained using the third training set and the fourth training set to obtain a target anal edge detection model that meets the sixth preset convergence condition. The target anal edge detection model can be used as the target anal upper edge detection model or as the target anal lower edge detection model.

[0090] The beneficial effects of this application are as follows: This application determines the average pressure of each channel in the anorectal pressure cloud map within a preset time period; it finds the first peak channel and the second peak channel with the largest average pressure in each channel within the rectum and anus, respectively, and determines the pressure measurement anatomical positions corresponding to the first peak channel and the second peak channel as the rectal peak position and the anal peak position, respectively; it interpolates the pressure values ​​of each channel to obtain interpolated pressure values; it determines the rectal characteristic value within the rectum and the anal characteristic value within the anus based on the interpolated pressure value and the average pressure value; wherein, the characteristic values ​​include the interpolated average pressure value, peak ratio, minimum pressure ratio, and pressure difference; it determines the rectal edge channel and the anal edge channel from the anorectal pressure cloud map according to the rectal characteristic value and the anal characteristic value, respectively, and determines the pressure measurement anatomical positions corresponding to the rectal edge channel and the anal edge channel as the rectal edge position and the anal edge position, respectively. Therefore, this application, by determining the average pressure of each channel in the anorectal pressure cloud map within a preset time period, can preliminarily understand the pressure distribution of each channel within that time period. It identifies the first and second peak channels with the highest average pressure within the rectum and anus, respectively, and determines the corresponding anatomy locations as the rectal and anal peak locations. This accurately captures the areas with the highest pressure, thus precisely locating the peak locations of the rectum and anus. Interpolation of the pressure values ​​of each channel allows for a more refined pressure distribution, leading to the calculation of more accurate interpolated average pressure, peak ratio, minimum pressure ratio, and pressure difference. These characteristics contribute to a more comprehensive understanding of the anorectal pressure distribution. Based on the rectal and anal characteristic values, the rectal and anal edge channels are determined from the anorectal pressure cloud map. The corresponding anatomy locations for these edge channels are the rectal and anal edge locations. Since characteristic value analysis provides detailed pressure distribution information, this characteristic-based edge channel determination method enables precise location of the anorectal anatomy locations.
