Description
Technical Field
[0001] The invention relates to the technical field of operating room lighting control, in particular to a lighting control method for nursing lights in an operating room. Background Art
[0002] The lighting system in the operating room is a key factor in ensuring the safety and efficiency of surgery. Modern operating room lighting systems use shadowless lamp technology, which uses multiple light sources to illuminate from different angles to ensure that the surgical area is evenly illuminated and reduce shadows. In addition to adjusting the brightness, the shadowless lamps in modern operating rooms can also adjust the spot size and focal length to meet different surgical needs. These lamps are usually equipped with manual or remote control adjustment systems, allowing doctors to adjust the position and brightness of the lights at any time according to the needs during the operation. In order to further optimize the surgical field of view, modern operating rooms may also be equipped with intelligent control systems that automatically adjust the intensity and direction of the lights through sensors to adapt to changes in the surgical scene. The development of these technologies has greatly improved the functionality of the operating room and the safety of surgery, allowing doctors to operate under optimal visual conditions, thereby improving the success rate of surgery.
[0003] In the existing operating room lighting system, different surgeons have different habits of using shadowless lamp brightness. One operating room can be used by multiple surgeons. Before each operation, the surgeon has to adjust the brightness of the shadowless lamp according to his or her brightness habits, which is time-consuming. At the same time, the direct exposure of the shadowless lamp to the human eye will cause eye fatigue, affecting the safety of the patient and the vision of the doctor. When the shadowless lamp is adjusting the irradiation direction, if a light spot is generated on the surgical area, it will affect the operation.
[0004] This solution proposes to count the pre-adjusted brightness for a standard number of surgeries, implement a brightness record planning strategy, obtain the standard pre-adjusted brightness of the surgeon, obtain the execution area of the shadowless lamp and the rotation trajectory during movement, implement a position adjustment strategy, and adjust the position of the shadowless lamp.

[0086] Move the execution circle corresponding to the shadowless lamp on the first limited track and the second limited track.
[0087] The present invention has the following beneficial effects:
[0088] 1. The operating room nursing lighting control method uses the brightness of the shadowless lamp at the end of the operation as the preset brightness for the next operation for the second surgeon who performs concentrated operations. The brightness of the shadowless lamp at the end of the last operation of the surgeon is retained and used as the preset brightness for the next operation by default. The brightness habit of the surgeon is retained, which reduces the time for the surgeon to adjust the brightness of the shadowless lamp and saves time.
[0089] 2. The lighting control method for operating room nursing, for the second surgeon, obtains the upper and lower brightness limits of the surgical set, divides the brightness into multiple brightnesses by setting the brightness interval, and obtains multiple brightness intervals. The value in each brightness interval is the brightness of the shadowless lamp that can be recognized by the surgeon, that is, when the brightness of the shadowless lamp changes within the same brightness interval, the surgeon cannot recognize it. However, when the brightness of the shadowless lamp changes within different intervals, the surgeon cannot recognize it. The multiple pre-adjusted brightnesses in the surgical set are unified into different brightness intervals, and the multiple pre-adjusted brightnesses are classified according to the brightness intervals that can be recognized by the human eye, in preparation for the subsequent calculation of the standard pre-adjusted brightness.
[0090] 3. The lighting control method for operating room nursing uses, for the second surgeon, the midpoint value of the brightness interval is obtained as the brightness that the human eye can recognize in this brightness interval, and multiple pre-adjusted brightnesses in the brightness interval are unified as the midpoint value of the brightness interval, and the calculation is simplified to obtain the interval value. The interval value represents the frequency of the surgeon using each brightness interval. The interval value is divided by the standard number of times to obtain the interval weight. The interval weight represents the probability that the surgeon adjusts the brightness of the shadowless lamp in each brightness interval among all brightness intervals. The interval weight is multiplied by the midpoint value to obtain the branch brightness. The sum of all branch brightnesses is used as the pre-adjusted brightness after the second surgeon completes the standard number of surgeries. The pre-adjusted brightness of the standard number of surgeries is counted, and the standard pre-adjusted brightness is calculated using the weighted average method. The pre-adjusted brightness calculated through historical records fits the habits of the surgeon and is more convincing and practical.
[0091] 4. The method for controlling the lighting of operating room nursing care obtains the pre-adjusted brightness of all the second surgeons when the first surgeon performs surgery for the first time, calculates the average value, and uses it as the pre-adjusted brightness for the first surgeon during surgery. By drawing on the lighting preferences and practices of other more experienced doctors, visual problems or misoperations during surgery caused by improper lighting can be reduced. By using the average brightness setting of experienced doctors, it can help ensure that the lighting in the surgical area is appropriate, thereby helping to improve the efficiency and safety of surgery.
[0092] 5. The operating room nursing lighting control method obtains the execution trajectory outside the surgeon's field of view and pays attention to its two endpoints, which are recorded as the first intersection and the second intersection respectively. This helps to optimize the position setting of the shadowless lamp and avoid the light directly entering the doctor's eyes or causing unnecessary reflections and glare. This can reduce visual interference and enable the doctor to focus more on the operation itself.
[0093] 6. The lighting control method for operating room nursing is to make a plane perpendicular to the horizontal plane through the height of the cone where the field of view area is located to obtain the demarcation point. If the shadowless lamp illuminates the operating table at the demarcation point, the shadowless lamp will also illuminate the back of the surgeon's head while illuminating the operating table, increasing the light spot on the operating table. Therefore, the shadowless lamp needs to avoid illuminating the operating table around the demarcation point, set a standard interval, determine the first marking point and the second marking point, determine the first track and the second track, and when illuminating the first track and the second track, the shadowless lamp will not directly shine into people's eyes during the process of illuminating the operating table, and will not cause light spots on the operating table due to illuminating people, thereby increasing the light brightness of the operation and reducing the light stimulation to the surgeon.
[0094] 7. The method for controlling the lighting for nursing in the operating room comprises: obtaining a dividing edge, which is the side where the surgeon stands during the operation, making a dividing surface, obtaining the intersection of the dividing edge and the rotation trajectory, obtaining a dividing point, obtaining a first execution trajectory when there is a dividing point on the first trajectory and no dividing point on the second trajectory, and moving the execution circle corresponding to the shadowless lamp on the first execution trajectory; obtaining a first limited trajectory and a second limited trajectory when there is a dividing point on the first trajectory and a dividing point on the second trajectory, and moving the execution circle corresponding to the shadowless lamp on the first limited trajectory and the second limited trajectory; otherwise, when there is no dividing point on the first trajectory and no dividing point on the second trajectory, moving the execution circle corresponding to the shadowless lamp on the first trajectory and the second trajectory; shadows during surgery are a common problem, especially during deep surgery. By adjusting the shadowless lamp, the shadows generated by the surgical team itself or surgical instruments can be effectively reduced, ensuring uniform and continuous light in the surgical area. The use of dividing points allows the shadowless lamp to be personalized according to the type of surgery and the specific needs of the surgeon. Each surgery and each doctor may have different requirements for the intensity and angle of light, and precise control can provide the most suitable lighting conditions. By setting the dividing points on the rotation trajectory, the shadowless lamp can adjust the light source position according to the surgical process and the position of the surgeon. This flexibility keeps the surgical area in the best visual conditions, that is, the shadowless lamp should avoid irradiating the operating table from behind the patient as much as possible.

[0114] The execution of the brightness record planning strategy includes:
[0115] The surgeon whose number of completed operations is not equal to 0 is recorded as the second surgeon;
[0116] For each second surgeon:
[0117] For any surgery in the set:
[0118] Obtain the brightness of the shadowless lamp at the end of the operation as the preset brightness for the next operation;
[0119] For the second surgeon, for surgeries that are concentrated in a group, the brightness of the shadowless lamp at the end of the surgery will be used as the pre-adjusted brightness for the next surgery. The brightness of the shadowless lamp at the end of the last surgery of the surgeon will be retained and used as the pre-adjusted brightness for the next surgery by default. The brightness habits of the surgeon will be retained, reducing the time the surgeon spends adjusting the brightness of the shadowless lamp and saving time.
[0120] Get the minimum pre-adjusted brightness in the surgical set, recorded as the lower limit brightness;
[0121] Obtain the maximum pre-adjusted brightness in the surgical set, recorded as the upper limit brightness;
[0122] Setting a brightness interval, wherein the brightness interval is a value at which the human eye can recognize changes in light intensity;
[0123] When (upper limit brightness - lower limit brightness) / brightness interval is an integer:

[0127] Calculate the lower limit brightness + brightness interval * 1 = first brightness;
[0128] Calculate the lower limit brightness + brightness interval * 2 = second brightness;
[0129] Until
[0130] Calculate the lower limit brightness + brightness interval * m = mth brightness, mth brightness ≥ upper limit brightness;
[0131] The interval formed by the lower limit brightness and the first brightness is recorded as the first brightness interval, the interval formed by the first brightness and the second brightness is recorded as the second brightness interval, and the interval formed by the m-1th brightness and the mth brightness is recorded as the mth brightness interval.
[0132] For the second surgeon, the upper and lower brightness limits of the surgical set are obtained, and multiple brightnesses are divided by setting the brightness interval to obtain multiple brightness intervals. The value in each brightness interval is the brightness of the shadowless lamp that can be recognized by the surgeon. That is, when the brightness of the shadowless lamp changes within the same brightness interval, the surgeon cannot recognize it. However, when the brightness of the shadowless lamp changes in different intervals, the surgeon cannot recognize it. The multiple pre-adjusted brightnesses in the surgical set are unified into different brightness intervals, and the multiple pre-adjusted brightnesses are classified according to the brightness intervals that can be recognized by the human eye, in preparation for the subsequent calculation of the standard pre-adjusted brightness.
[0133] The execution of the brightness record planning strategy includes:
[0134] The number of preset brightnesses in the brightness interval is recorded as the interval value;
[0135] Get the interval value of each brightness interval;
[0136] For a brightness range:

[0138] Get the midpoint value of the brightness range;
[0139] Calculate the interval weight * midpoint value, and record the result as branch brightness;
[0140] Obtain the branch brightness of all brightness intervals, calculate the sum of all branch brightness, and record the result as the standard pre-adjusted brightness;
[0141] Then, after the second surgeon completes the standard number of operations, the pre-adjusted brightness of the shadowless lamp used by the second surgeon will be the standard pre-adjusted brightness.
[0142] For the second surgeon, the midpoint value of the brightness interval is obtained as the brightness that the human eye can recognize in this brightness interval. Multiple pre-adjusted brightnesses in the brightness interval are unified as the midpoint value of the brightness interval to simplify the calculation and obtain the interval value. The interval value represents the frequency of the surgeon using each brightness interval. The interval value is divided by the standard number of times to obtain the interval weight. The interval weight represents the probability that the surgeon adjusts the brightness of the shadowless lamp in each brightness interval among all brightness intervals. The interval weight is multiplied by the midpoint value to obtain the branch brightness. The sum of all branch brightnesses is used as the pre-adjusted brightness after the second surgeon completes the standard number of surgeries. The pre-adjusted brightness of the standard number of surgeries is counted, and the standard pre-adjusted brightness is calculated using the weighted average method. The pre-adjusted brightness calculated based on historical records fits the surgeon's habits and is more convincing and practical.
[0143] The execution of the brightness estimation strategy includes:
[0144] The surgeon whose number of completed operations is 0 is recorded as the first surgeon;
[0145] Obtaining the preset brightness of all second surgeons, which are recorded as the first preset brightness, the second preset brightness, and so on to the nth preset brightness;
[0146] Execute the following formula:
[0147] Calculate (first preset brightness + second preset brightness up to nth preset brightness) / n = the preset brightness of the first surgeon during the first operation.
[0148] When the first surgeon performs surgery for the first time, the pre-adjusted brightness of all the second surgeons is obtained and the average is calculated as the pre-adjusted brightness for the first surgeon's surgery. The lighting preferences and practices of other more experienced doctors are learned to reduce visual problems or misoperations during surgery caused by improper lighting. By using the average brightness setting of experienced doctors, it can help ensure that the lighting in the surgical area is appropriate, thereby helping to improve the efficiency and safety of surgery.
[0149] The execution position adjustment strategy includes:
[0150] The center of the bottom surface of the execution area is recorded as the execution center;
[0151] The rotation trajectory is the motion trajectory of the center of the circle when the shadowless lamp rotates, and the shape of the rotation trajectory is a circle;
[0152] When the surgeon performs the surgery:
[0153] Obtain the rotation trajectory outside the surgeon's field of view and record it as the execution trajectory;
[0154] The two endpoints of the execution trajectory are recorded as the first intersection point and the second intersection point respectively.
[0155] Obtaining the execution trajectory outside the surgeon's field of view and paying attention to its two endpoints, recorded as the first intersection point and the second intersection point, helps optimize the position setting of the shadowless lamp and prevent the light from directly shining into the surgeon's eyes or causing unnecessary reflections and glare. This can reduce visual interference and allow the surgeon to focus more on the surgery itself.
[0156] The execution position adjustment strategy includes:

If the shadowless lamp illuminates the operating table at the dividing point, the shadowless lamp will also illuminate the back of the surgeon's head while illuminating the operating table, increasing the light spot on the operating table. Therefore, the shadowless lamp needs to avoid illuminating the operating table around the dividing point, set a standard interval, determine the first marking point and the second marking point, determine the first track and the second track, and when irradiating the first track and the second track, the shadowless lamp will not directly shine into people's eyes during the irradiation of the operating table and will not cause light spots on the operating table due to irradiating people, thereby increasing the light brightness of the operation and reducing the light stimulation to the surgeon.

[0181] On the first trajectory, recording the trajectory between the first intersection point and the first division point as a first limited trajectory;
[0182] Record the division point on the second trajectory as the second division point;
[0183] Recording the trajectory between the second intersection point and the second dividing point on the second trajectory as a second limited trajectory;

By adjusting the shadowless lamp, the shadows generated by the surgical team itself or surgical instruments can be effectively reduced, ensuring uniform and continuous light in the surgical area. The use of dividing points allows the shadowless lamp to be personalized according to the type of surgery and the specific needs of the surgeon. Each surgery and each doctor may have different requirements for the intensity and angle of light, and precise control can provide the most suitable lighting conditions. By setting the dividing points on the rotation trajectory, the shadowless lamp can adjust the light source position according to the surgical process and the position of the surgeon. This flexibility keeps the surgical area in the best visual conditions. That is, the shadowless lamp should avoid irradiating the operating table from behind the patient as much as possible.
[0187] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
