Specifically, the gynecological clinical voyeurism device of the present application includes blades, and also includes a module for realizing position control, namely: a pressure monitoring unit 100, a blade angle adjustment unit 200 and a position adjustment unit 300, which are respectively described as follows: The pressure monitoring unit 100 in the present application is mainly used to monitor the pressure of the blades on the target speculum during the process of being placed in the patient's examination area.

[0020] In a specific implementation, the pressure monitoring unit 100 monitors the pressure of the patient's examination part on the blade of the target speculum through a pressure sensor, wherein the pressure sensor can be a piezoresistive pressure sensor or a vibrating wire pressure sensor, and records the pressure of the patient's examination part on the blade of the target speculum at a frequency of once per second; for example, referring to Figure 2 As described above, this figure is a schematic diagram of the structure of monitoring the pressure on the blade shown in this embodiment, wherein the monitoring process is: after the blade on the target speculum is inserted into the patient's examination part, the pressure on the surface of the blade is monitored by a pressure sensor, and the monitored pressure is transmitted to the controller of the target speculum. In other embodiments, other monitoring methods can also be used, which will not be repeated here.

In this figure, the blades are driven to perform corresponding actions by the rotation of the bearing, that is: when the bearing rotates to the right, the upper blade and the lower blade are spread out to both sides, and when the bearing rotates to the left, the upper blade and the lower blade are closed to the middle. In the target speculum, the spreading angle of the upper blade and the lower blade is controlled by controlling the number of rotations of the bearing.

[0022] In addition, the blade angle adjustment unit 200 in the present application is mainly used to adjust the expansion amplitude of the blades of the target speculum when examining a patient based on the fluctuation characteristics of all pressures obtained through monitoring, and to determine the driving force range of the blades on the target speculum during the adjustment process. The angle of the target speculum is adjusted through the driving force range and the initial angle of the target speculum to obtain the confidence angle of the target speculum during the patient examination process.

[0023] In some embodiments, in order to adjust the expansion amplitude of the blades of the target speculum when examining a patient according to the fluctuation characteristics of all pressures obtained by monitoring, and determine the driving force range of the blades on the target speculum during the adjustment process, the blade angle adjustment unit 200 in the present application is also used to determine the fluctuation characteristics of all pressures obtained by monitoring; monitor the expansion amplitude of the blades of the target speculum when examining a patient; adjust the expansion amplitude according to the fluctuation characteristics to obtain multiple driving pressures; and determine the driving force range of the blades on the target speculum during the adjustment process according to all the driving pressures.

[0024] In specific implementation, determining the fluctuation characteristics of all pressures obtained by monitoring can be achieved in the following manner, namely: arranging all pressures obtained by monitoring in chronological order of recording time, using the arranged sequence as a pressure sequence, selecting a group of adjacent pressures in the pressure sequence as selected adjacent pressures, subtracting the first pressure from the second pressure obtained in the selected adjacent pressures, using the subtracted value as the pressure difference of the selected adjacent pressures, and continuing to determine the pressure difference of the remaining adjacent pressures, wherein the pressure difference represents a parameter value of the degree of difference between adjacent pressures on the blade when examining a patient, and using all pressure differences as the fluctuation characteristics of all pressures obtained by monitoring, wherein the fluctuation characteristics represent the characteristics of the degree of pressure fluctuation of the blade when examining a patient; in other embodiments, other methods may also be used for determination, which are not limited here.

[0025] In specific implementation, monitoring the expansion amplitude of the blades of the target speculum when examining a patient can be achieved in the following manner, namely: monitoring the expansion amplitude of the blades of the target speculum when examining a patient through an existing amplitude monitoring device (such as a ruler, Callascope), wherein the expansion amplitude represents the expansion amplitude of the blades on the target speculum, and is used to analyze the visible range of the patient's examination area; adjusting the expansion amplitude according to the fluctuation characteristics, and obtaining multiple driving pressures can be achieved in the following manner, namely: extracting all positive pressure differences from the fluctuation characteristics, performing a natural exponential operation on the expansion amplitude, multiplying the inverse of the value obtained by the natural exponential operation by each extracted pressure difference, and using each multiplied value as a driving pressure to obtain multiple driving pressures, wherein the driving pressure represents the pressure that needs to be increased by the blades on the target speculum during the driving expansion process, and is used to analyze the expansion status of the blades on the target speculum; in other embodiments, other methods can also be used for determination, which are not limited here.

[0026] In specific implementation, the driving force range of the blades on the target speculum during the adjustment process can be determined based on all driving pressures in the following manner, namely: calculate and monitor the average pressure of all pressures, add the average pressure to the minimum driving pressure, and use the added value as the lower limit of the driving force range; add the average pressure to the maximum driving pressure, and use the added value as the upper limit of the driving force range; the interval formed by the upper limit and the lower limit is used as the driving force range of the blades on the target speculum during the adjustment process. In other embodiments, other methods can be used to determine, which are not limited here.

[0027] It should be noted that the driving force range in the present application indicates the range of force required for the blades of the target speculum to drive and expand the patient's examination part, and is used to adjust the pressure of the blades on the target speculum when it is placed into the patient's examination part, thereby increasing the driving accuracy of the target speculum when examining the patient.

The upper limit value of the driving force range is determined by subtracting the upper limit value in the driving force range from the lower limit value in the driving force range, performing a logarithmic operation with a base of 2 on the subtracted value, subtracting the value obtained by the logarithmic operation from the initial angle, and using the subtracted value as the lower limit value of the angle fluctuation range, and using the range composed of the upper limit value of the angle fluctuation range and the lower limit value of the angle fluctuation range as the angle fluctuation range of the target speculum, wherein the angle fluctuation range represents the range of angle change of the target speculum caused by changes in pressure on the blade, and is used to adjust and analyze the angle of the target speculum; in other embodiments, other methods can also be used for determination, which are not limited here.

[0030] In addition, in a specific implementation, the angle of the target speculum is adjusted according to the angle fluctuation range, and the adjusted angle is used as the confidence angle of the target speculum during the patient examination process. This can be achieved in the following manner, namely: subtract the lower limit value from the upper limit value of the angle fluctuation range, and use the subtracted value as the first value, add the first value to the initial angle, divide the first value by the added value, subtract the added value from 1, multiply the subtracted value by the first value, and use the multiplied value as the adjusted angle. The adjusted angle is used as the confidence angle of the target speculum during the patient examination process. In other embodiments, other methods may be used for determination, which are not limited here.

[0031] It should be noted that the confidence angle in this application is a parameter value that reflects the confidence level of the angle of the target speculum after the pressure on the blade changes, and is used to predict the angle of the target speculum, thereby making the angle of the target speculum reach a comfortable angle.
