Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a method for adjusting the illumination optics of an operating microscope. Background Art

[0002] In certain surgical procedures, such as during the suturing of fine blood vessels and nerves, since the objects to be sutured or other operations are relatively small, it is necessary to use an operating microscope for treatment, and the illumination brightness of the operating microscope has a great impact on the operation accuracy of the surgical operator.

[0003] Specifically, in the patent application for invention CN202211464042.1, "A Large Magnification Ratio Illumination System for an Operating Microscope", by adopting an off-axis illumination system, the design is simple, and the center position of the illumination surface is constant, always coinciding with the center position of the surgical field observed by the operating microscope. However, the prior art has not considered how to achieve adaptive adjustment of the optical brightness of the operating microscope, thus unable to improve the efficiency and accuracy of surgical treatment.

[0004] In view of the above technical problems, the present invention provides a method for adjusting the illumination optics of an operating microscope and an operating microscope. Summary of the Invention

[0005] To achieve the object of the present invention, the present invention adopts the following technical solutions:

[0006] According to one aspect of the present invention, a method for adjusting the illumination optics of an operating microscope is provided.

[0007] A method for adjusting the illumination optics of an operating microscope specifically includes:

[0008] S1 Determine the brightness safety adjustment range of the operating microscope using the surgical type, obtain the operation data of the surgical type at different brightnesses, and determine the recommended brightness using the operation data and the service life of the illumination device at different brightnesses;

[0009] S2 Control the illumination of the operating microscope with the recommended brightness, determine the operation error data of the surgical operator based on the displayed image of the operating microscope, and determine the adaptation coefficient of the recommended brightness in combination with the operation time of the surgical operator in different operation processes. When the adaptation coefficient does not meet the requirements, proceed to the next step;

[0010] S3 Using the brightness safety adjustment range as a constraint condition, obtain the deviation between the recommended brightness and the upper endpoint of the brightness safety adjustment range, and determine the target adjustment brightness of the illumination device based on the deviation situation, the adaptation coefficient of the recommended brightness, and the current surgical operation time;

[0011] S4 When the operation error data of the surgical operator at the target adjusted brightness meets the requirements, stop adjusting the brightness of the lighting device.

[0012] A further technical solution lies in that the brightness safety adjustment range of the surgical microscope is determined according to the body part of the operation object corresponding to the surgical type, and specifically, the brightness safety adjustment range of the surgical microscope is determined through a pre-set brightness adjustment range.

[0013] A further technical solution lies in that the operation data includes the operation duration and the number of operation errors of different processes under different surgical operation times.

[0014] A further technical solution lies in that the service life of the lighting device at different brightnesses is determined according to the model of the lighting device.

[0015] A further technical solution lies in that the method for determining the recommended brightness is as follows:

[0016] Determine the number of operation errors under different surgical operation times at a specific brightness according to the operation data, and determine the number of error surgical operations based on the number of operation errors, and determine the operation reliability at the specific brightness according to the number of error surgical operations;

[0017] Determine the life influence value at the specific brightness by using the service life of the lighting device at the specific brightness;

[0018] Determine the comprehensive service reliability at the specific brightness based on the ratio of the operation reliability to the life influence value, and determine whether the specific brightness is the recommended brightness through the comprehensive service reliability.

[0019] A further technical solution lies in that determining whether the specific brightness is the recommended brightness through the comprehensive service reliability specifically includes:

[0020] Take the specific brightness with the maximum comprehensive service reliability as the recommended brightness.

[0021] A further technical solution lies in that judging whether the operation error data of the surgical operator meets the requirements specifically includes:

[0022] Take the operation error data of the surgical operator at the target adjusted brightness as the real-time operation error data, and determine the real-time operation error number of the surgical operator by using the real-time operation error data;

[0023] Determine whether the operation error data of the surgical operator meets the requirements by using the real-time error operation number.

[0024] On the other hand, the present application provides a surgical microscope, which adopts the above-mentioned method for adjusting the illumination optics of a surgical microscope, specifically including:

[0025] A brightness recommendation processing module, an adaptation coefficient evaluation module, a brightness adjustment module, and a stop adjustment judgment module;

[0026] Among them, the brightness recommendation processing module is responsible for determining the safe adjustment range of the brightness of the surgical microscope by using the surgical type, obtaining the operation data of the surgical type at different brightnesses, and determining the recommended brightness by using the operation data and the service life of the lighting device at different brightnesses;

[0027] The adaptation coefficient evaluation module is responsible for controlling the illumination of the surgical microscope with the recommended brightness, determining the operation error data of the surgical operator according to the displayed image of the surgical microscope, and determining the adaptation coefficient of the recommended brightness in combination with the operation time of the surgical operator in different operation processes;

[0028] The brightness adjustment module is responsible for taking the safe adjustment range of the brightness as a constraint condition, obtaining the deviation between the recommended brightness and the upper endpoint of the safe adjustment range of the brightness, and determining the target adjustment brightness of the lighting device based on the deviation, the adaptation coefficient of the recommended brightness, and the current surgical operation time;

[0029] The stop adjustment judgment module is responsible for stopping the brightness adjustment of the lighting device when the operation error data of the surgical operator at the target adjustment brightness meets the requirements.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. In the present invention, the recommended brightness is determined by using the operation data and the service life of the lighting device at different brightnesses, which not only considers the determination of the operation reliability at different brightnesses from two angles of the operation error data and the operation duration at different brightnesses, but also considers the influence of different brightnesses on the service life of the lighting device, thereby realizing the evaluation of the recommended brightness from multiple angles and ensuring the safety of surgical operations and the service life of the lighting device.

[0032] 2. In the present invention, the target adjustment brightness of the lighting device is determined based on the deviation, the adaptation coefficient of the recommended brightness, and the current surgical operation time, which avoids the influence of too large a target adjustment brightness on the operation object due to too large an adjustment step, and at the same time, by considering the adaptation coefficient of the recommended brightness and the current surgical operation time, it also ensures the reliability of surgical operations and avoids the technical problems of too many operation error times or too long operation time caused by insufficient brightness.

[0033] Other features and advantages will be set forth in the following description, and the objectives and other advantages of the present invention are achieved and obtained by the structures particularly pointed out in the description and the drawings.

[0046] It should be noted that the operation data includes the operation duration and the number of operation errors of different processes under different numbers of surgical operations.

[0047] It can be understood that the service life of the lighting device under different brightnesses is determined according to the model of the lighting device.

[0048] Specifically, as Figure 2 shown, the method for determining the recommended brightness is:

[0051] Determine the comprehensive service reliability at the specific brightness based on the ratio of the operation reliability to the life influence value, and determine whether the specific brightness is the recommended brightness through the comprehensive service reliability.

[0052] In addition, it should be noted that determining whether the specific brightness is the recommended brightness through the comprehensive service reliability specifically includes:

[0053] Take the specific brightness with the maximum comprehensive service reliability as the recommended brightness.

[0054] Furthermore, it should be noted that the method for determining the recommended brightness is:

[0055] Determine the operation duration of different processes under different numbers of surgical operations at a specific brightness according to the operation data, and use the operation duration to determine the operation process with abnormal time consumption. Take the number of surgical operations including the operation process with abnormal time consumption as the number of operations with abnormal time consumption;

[0056] Obtain the service life of the lighting device at the specific brightness, and combine the number of operations with abnormal time consumption to determine the comprehensive service reliability at the specific brightness by using a mapping model;

[0057] Determine whether the specific brightness is the recommended brightness through the comprehensive service reliability.

[0058] Further, it should be noted that the method for determining the recommended brightness is as follows:

Determine whether the number of operation times with abnormal time consumption meets the requirements. If so, proceed to the next step; if not, determine that the specific brightness does not belong to the recommended brightness;

[0062] Determine the abnormal operation value under different surgical operation times based on the number of operation error times under different surgical operation times and the operation duration of different processes, and determine the operation reliability at the specific brightness through the abnormal operation value under different surgical operation times;

[0063] Use the service life of the lighting device at the specific brightness to determine the life influence value at the specific brightness, determine the comprehensive use reliability at the specific brightness based on the ratio of the operation reliability to the life influence value, and determine whether the specific brightness is the recommended brightness through the comprehensive use reliability.

[0064] S2 Perform lighting control of the surgical microscope at the recommended brightness, determine the operation error data of the surgical operator according to the display image of the surgical microscope, and combine the operation time of the surgical operator in different operation processes to determine the adaptation coefficient of the recommended brightness. When the adaptation coefficient does not meet the requirements, proceed to the next step;

When the adaptation coefficient is less than the preset coefficient threshold, it is determined that the adaptation coefficient of the recommended brightness does not meet the requirements.

[0069] Furthermore, when the adaptation coefficient meets the requirements, there is no need to adjust the brightness of the lighting device.

[0070] In addition, it should be noted that the method for determining the adaptation coefficient of the recommended brightness is as follows:

[0078] S24 determines the operation processing reliability of different operation processes through the process handling reliability and the outlier of the operation time of different operation processes, and judges whether there is an operation process whose operation processing reliability does not meet the requirements. If so, it proceeds to the next step. If not, it is determined that the adaptation coefficient of the recommended brightness meets the requirements;

[0079] S25 determines the adaptation coefficient of the recommended brightness according to the average value of the operation processing reliability of different operation processes.

[0080] S3 takes the brightness safety adjustment range as a constraint condition, obtains the deviation situation between the recommended brightness and the upper endpoint of the brightness safety adjustment range, and determines the target adjustment brightness of the lighting device based on the deviation situation, the adaptation coefficient of the recommended brightness, and the current surgical operation time;

[0081] Specifically, it should be noted that as Figure 4 shown, the method for determining the target adjustment brightness of the lighting device is:

[0082] Determine the adjustment step range of the lighting device according to the deviation situation;

[0086] When both the recommended adjustment step and the matching adjustment step are greater than the upper endpoint value of the adjustment step range, the upper endpoint value of the adjustment step range is used to determine the brightness adjustment step of the lighting device;

[0087] When both the recommended adjustment step and the matching adjustment step are less than the lower endpoint value of the adjustment step range, the lower endpoint value of the adjustment step range is used to determine the brightness adjustment step of the lighting device;

[0088] When either the recommended adjustment step or the matching adjustment step is within the adjustment step range, the maximum value of the recommended adjustment step and the matching adjustment step within the adjustment step range is used to determine the brightness adjustment step of the lighting device.

[0089] In addition, it should be noted that the method for determining the target adjustment brightness of the lighting device is as follows:
