Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a control method and system for an endoscopic surgical display device, and a display device thereof. Background Technology

[0002] In fields such as medical, industrial inspection, and security monitoring, the display stability, real-time performance, and anti-interference capabilities of a monitor directly affect the quality and safety of operations. The requirements for monitors are particularly stringent in medical settings. According to the IEC 60601-1-2 standard, medical monitors must possess good electromagnetic compatibility (EMC) to cope with the strong electromagnetic interference generated by equipment such as electrosurgical units, ultrasound machines, and MRI machines in environments such as operating rooms and intensive care units, preventing image distortion, flickering, or blackouts from affecting diagnosis and treatment and endangering patient safety.

[0003] As specialized equipment, endoscopic surgical display devices have extremely high real-time requirements, with image latency needing to be controlled within milliseconds. Otherwise, it can easily lead to desynchronization between operation and imaging, increasing surgical risks. Therefore, high-speed interfaces, low-latency chips, hardware acceleration technology, and high-response panels are typically employed to reduce motion blur.

[0004] Its core technical defect is the display abnormality caused by electromagnetic interference, which mainly includes two types: First, the high-frequency pulse (300kHz–5MHz) generated when the electrosurgical unit is working is coupled through power supply or spatial radiation, causing snow or black screen; Second, electrostatic discharge (ESD) enters through the shell or interface, which may cause chip breakdown, hardware damage or signal interruption, causing screen freezing, discoloration or black screen. Summary of the Invention

[0005] The purpose of this invention is to provide a control method and system for an endoscopic surgical display device, as well as a display device, which effectively eliminates the black screen phenomenon caused by momentary abnormalities and shortens the waiting time for the screen to recover.

[0006] To achieve the above objectives, the present invention is implemented using the following technical solution: In a first aspect, the present invention provides a method for controlling an endoscopic surgical display device, comprising: Acquire the video source signal and determine if any video source signal abnormality has occurred; In response to an anomaly in the video source signal, the anomaly re-judgment operation is repeatedly performed on the video source signal and the number of anomaly re-judgments C is counted. If the abnormal re-judgment result of the video source signal is still abnormal, and the number of abnormal re-judgments C is greater than the preset threshold N, then a restart signal is sent to reacquire the video source signal. If the abnormal re-judgment result of the video source signal is normal and the number of abnormal re-judgments C is not greater than the preset threshold N, then the video source signal is output and the number of abnormal re-judgments C is cleared to zero.

[0007] Through the above technical solutions, the system can promptly identify and quickly respond to abnormal conditions of the video source signal, ensuring that the video source signal is transmitted as stably as possible. The re-judgment mechanism and clearly defined threshold settings enable the system to effectively avoid false alarms of video source anomalies due to short-term fluctuations, improving the overall accuracy and reliability of the system. It can handle abnormal conditions of different types of video source signals and has strong adaptability.

[0008] Optionally, determining whether a video source signal abnormality has occurred includes: acquiring at least one characteristic parameter of the video source signal; if the characteristic parameter falls within a preset normal parameter range, then the video source signal is determined to be normal; otherwise, the video source signal is determined to be abnormal.

[0009] By setting up a feature parameter comparison design, this method can quickly determine the normality of the video source signal and effectively solve various abnormal situations that may occur during the transmission of the video source signal, thereby ensuring the reliability and stability of the system.

[0010] Optionally, the feature parameters include at least one of pixel clock, synchronization polarity, total pixels, and edge parameters.

[0011] By comprehensively optimizing pixel clock, synchronization polarity, total pixel count, and edge parameters, technical challenges in achieving high-resolution and smooth display were resolved. At high resolution, increasing the total pixel count and optimizing edge parameters enhanced image detail and reduced image interference, thereby improving the integrity and stability of the display effect. Simultaneously, a stable and high-speed pixel clock and precise synchronization polarity ensured smooth image display and a flicker-free experience. Therefore, maintaining display smoothness and image detail at high resolution effectively prevented image quality degradation and improved the continuity of the screen visual experience.

[0012] Optionally, in response to an anomaly in the video source signal, an anomaly prompt message is generated and output.

[0013] By generating and outputting abnormal prompts, and immediately performing a re-evaluation of the video source signal when or before outputting the prompts, problems can be quickly located and corresponding measures can be taken. This solves the problem of system instability caused by abnormal video source signals and reduces the risk of false alarms and user misjudgments.

[0014] Optionally, the abnormal prompt information may be output in at least one of the following ways: lighting up an indicator light, triggering a buzzer, playing a voice message, or displaying text.

[0015] By incorporating technical features such as indicator lights, buzzers, voice and text displays, the system ensures that users can quickly and clearly detect any abnormalities from visual, auditory, and informational perspectives.

[0016] In a second aspect, the present invention also provides a control system for an endoscopic surgical display device, comprising: The signal acquisition module is used to acquire the video source signal; An anomaly detection module is used to determine whether an anomaly has occurred in the video source signal; The re-judgment and statistics module is used to repeatedly perform an anomaly re-judgment operation on the video source signal and count the number of anomaly re-judgments C in response to an anomaly in the video source signal. The control execution module is configured to, in response to the video source signal being in an abnormal state, send a restart signal to reacquire the video source signal if the abnormal re-judgment result is still abnormal and the number of abnormal re-judgments C is greater than a preset threshold N; or in response to the video source signal being in an abnormal state, output the video source signal and clear the number of abnormal re-judgments C to zero if the abnormal re-judgment result is normal and the number of abnormal re-judgments C is not greater than the preset threshold N.

[0017] By setting up signal monitoring modules, anomaly detection modules, re-judgment and statistics modules, and control execution modules, the control system of the endoscopic surgery display equipment can effectively reduce the impact of system failures caused by external signal anomalies, ensure the continuity and integrity of image quality, increase system stability, and enhance the user's visual recognition of the endoscopic surgery process.

[0018] Optionally, the control system further includes a reset circuit, configured to perform a reset operation on the signal acquisition module in response to receiving the restart signal, and trigger the signal acquisition module to reinitialize and output the video source signal.

[0019] Through simple and effective reset and initialization steps, the signal acquisition module can be quickly restored to normal operation, thereby improving the overall system performance, enhancing the stability of system control and the system's recovery capability, and ensuring the normal transmission of video source signals.

[0020] Thirdly, the present invention also provides an endoscopic surgical display device, comprising: The display panel; and the endoscopic surgical display device control system as described in any one of the preceding statements; The signal output terminal of the endoscopic surgery display device control system is connected to the signal input terminal of the display panel, and is used to provide video source signals to the display panel.

[0021] Because the display device is equipped with the aforementioned endoscopic surgery display device control system, it can provide a clear, stable and accurate image display for endoscopic surgery by working together with the modules within the system. This helps doctors observe the surgical site more accurately, improves the precision and safety of surgical operations, and optimizes the overall surgical outcome.

[0022] Compared with the prior art, the beneficial effects achieved by the endoscopic surgery display device control method and system and the display device of the present invention are as follows: 1. This invention can promptly identify and quickly respond to abnormal conditions of video source signals, ensuring that the video source signals are transmitted as stably as possible; the reasonable re-judgment mechanism and clear threshold setting enable the system to effectively avoid false alarms of video source abnormalities due to short-term fluctuations, improve the overall accuracy and reliability of the system, avoid display interruptions caused by single false detections, and the number of re-judgments N can be flexibly configured to adapt to the interference intensity of different surgical scenarios. 2. After detecting signal interference, this invention immediately triggers a buzzer and indicator light alarm to prompt doctors to operate with caution, rather than masking abnormal signals and causing misoperation. Attached Figure Description

[0023] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] Figure 1 This is a circuit diagram of an endoscopic surgery display device control method and system, and a display device, provided in some embodiments of the present invention. Figure 2 This is a flowchart of a method and system for controlling an endoscopic surgical display device, and a method for displaying the device, provided in some embodiments of the present invention. Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Example

[0026] like Figure 1-2 As shown, this embodiment provides a method for controlling an endoscopic surgical display device, including: Acquire video source signals and determine if any video source signal abnormalities have occurred; quickly identify abnormal signals through real-time monitoring of video source signals.

[0027] In response to the video source signal being abnormal, the abnormality re-judgment operation is repeatedly performed on the video source signal and the number of abnormality re-judgments C is counted. When the signal is abnormal, the re-judgment operation repeatedly checks the video source signal to ensure that the signal quality has been restored before outputting it, thus avoiding false restarts caused by a single detection result error.

[0028] If the anomaly reassessment result of the video source signal is still abnormal, and the number of anomaly reassessments C is greater than a preset threshold N, a restart signal is sent to reacquire the video source signal. By setting a threshold judgment mechanism between the number of reassessments C and the preset threshold N, the system possesses automatic detection and recovery functions, thus intelligently monitoring the video source signal status. Specifically, when an abnormal state is detected in the video source signal, the system will determine whether C is greater than N based on the comparison result between the number of reassessments C and the preset threshold N. If the condition is met, i.e., if an anomaly is still detected after multiple reassessments, the system will send a restart signal to achieve automatic recovery of the video source signal.

[0029] If the anomaly re-judgment result of the video source signal is normal, and the number of anomaly re-judgments C is not greater than a preset threshold N, then the video source signal is output and the number of anomaly re-judgments C is cleared to zero. If the video source signal returns to normal at this time, the system clears the number of re-judgments C to zero for subsequent use; this solves the problem of unnecessary frequent restarts caused by temporary anomalies that may occur during video transmission. By preset an appropriate threshold N, the system can maintain continuous output of the video source signal while ensuring stability, avoiding resource waste and increased operation frequency caused by frequent increases in the number of re-judgments C due to small fluctuations. This not only ensures reliable transmission of the video source signal but also improves the overall efficiency of the system and the user experience, thereby ensuring that the video system can operate more stably and efficiently.

[0030] In summary, the endoscopic surgery display device control method provided in this embodiment, by setting up video source signal anomaly detection, can quickly and accurately determine whether the video source signal is abnormal. Therefore, it can effectively perform a timely re-judgment operation when an abnormal signal occurs. Based on the comparison result of the number of re-judgments with a preset threshold, if the threshold is exceeded, a restart signal will be sent, thereby ensuring that the video source signal operates in a safe and controllable state. When the threshold condition is not met, the video source signal will be output immediately once the signal recovers. This reduces the possibility of the video source signal being in an abnormal state for a long time, thereby improving the stability and continuity of the video source signal.

[0031] In some embodiments, determining whether a video source signal anomaly has occurred includes: acquiring at least one characteristic parameter of the video source signal; if the characteristic parameter falls within a preset normal parameter range, then the video source signal is determined to be normal; otherwise, the video source signal is determined to be abnormal. It is understood that during video source signal transmission, the characteristic parameters of a normal signal typically fluctuate within a certain range. By analyzing these characteristic parameters, it can be determined whether the signal is normal. By comparing the characteristic parameters, it can be determined whether the video source signal is within the normal range. If the characteristic parameters conform to the preset normal parameter range, it indicates that the signal transmission is normal; otherwise, it indicates that the signal may have a problem. This comparison method can quickly and accurately identify abnormal video source signals, thereby enabling timely processing or repair.

[0032] In some embodiments, the characteristic parameters include at least one of pixel clock, synchronization polarity, total pixels, and edge parameters. It is understood that by setting at least one of pixel clock, synchronization polarity, total pixels, and edge parameters, problems such as unstable image transmission, poor synchronization, insufficient resolution, and edge mosaic in current display technologies can be solved, thereby improving the stability of image quality and the visual experience. These key technical features, through precise control of image transmission rate, synchronization time, image resolution, and edge processing, effectively solve the aforementioned image quality problems and improve the overall performance of the display device.

[0033] In some embodiments, in response to an anomaly in the video source signal, an anomaly prompt message is generated and output. It can be understood that when an anomaly occurs in the video source signal, the system can determine the root cause of the problem by checking various characteristic parameters and promptly generate an anomaly prompt message. Through this prompt message, operators can quickly locate the problem and take appropriate action. Furthermore, the system can also perform a re-evaluation of the video source signal after or simultaneously with the generation of the prompt message to further verify the signal's correctness. These measures significantly improve the stability and reliability of the video display system.

[0034] In some embodiments, the abnormality alert information is output in at least one of the following ways: illuminating an indicator light, triggering a buzzer, playing a voice message, or displaying text. It is understood that when the system detects an abnormality, it will alert the operator by driving an indicator light or a buzzer. Specifically, when the system recognizes an abnormality alert, it will control hardware devices, such as indicator lights and buzzers, to emit corresponding visual and auditory signals to remind the operator to pay attention to and handle the current abnormal situation. More specifically, a human-machine voice interaction function can also be integrated, combining voice prompts with LED indicator lights and buzzer alarms, such as a 2kHz frequency, 1-second interval, and 1-second periodic red LED flashing. Simultaneously, text prompts, such as "Signal abnormal, recovering, operate with caution," are displayed in a corner of the panel without obstructing the core area of ​​the surgical field of view. This multi-level warning system, using indicator lights, buzzers, or voice modules and text, prompts the doctor to operate with caution, rather than masking the abnormal signal and causing misoperation. Example

[0035] This embodiment provides a control system for an endoscopic surgical display device, which adopts the endoscopic surgical display device control method as described in Embodiment 1. The control system for the endoscopic surgical display device includes: a signal acquisition module, used to acquire video source signals; An anomaly detection module is used to determine whether an anomaly has occurred in the video source signal. When the number of re-evaluations C is less than a preset threshold N, the anomaly detection module will assess whether the output video source signal is normal. Similarly, when the display panel receives an input video source signal, this module will also assess and determine whether the video source signal output to the display panel is normal. Through real-time monitoring and automatic judgment, the system ensures that only normal video source signals are output to the display panel, preventing abnormal signals from entering the playback process at the source. This significantly improves the stability of video playback, avoids unpleasant experiences such as stuttering, frame skipping, or unclear images, ensures smooth and clear video images during endoscopic surgery, and ultimately reduces the surgical risks that may be caused by abnormal video source signals.

[0036] The re-judgment and statistics module is used to repeatedly perform an anomaly re-judgment operation on the video source signal and count the number of anomaly re-judgments C in response to an anomaly in the video source signal. The control execution module is configured to, in response to the video source signal being in an abnormal state, send a restart signal to reacquire the video source signal if the abnormal re-judgment result is still abnormal and the number of abnormal re-judgments C is greater than a preset threshold N; or in response to the video source signal being in an abnormal state, output the video source signal and clear the number of abnormal re-judgments C to zero if the abnormal re-judgment result is normal and the number of abnormal re-judgments C is not greater than the preset threshold N.

[0037] In summary, the endoscopic surgery display device control system provided in this embodiment can intelligently detect signal anomalies, automatically perform multiple re-judgments and attempts to recover, and, if recovery fails, reacquire the video source signal by restarting the signal monitoring module. These modules work together to enable the entire control system to cope with various anomalies in signal transmission, ensuring the stable and continuous operation of the display system and thus avoiding display problems caused by signal interruption. Through the cooperation of the signal monitoring module, anomaly detection module, re-judgment statistics module, and control execution module, a series of automated management processes from detection to recovery are achieved, effectively solving the stability problems that may be encountered during video source signal transmission.

[0038] In some embodiments, the control system further includes a reset circuit, configured to perform a reset operation on the signal acquisition module in response to receiving the restart signal, and trigger the signal acquisition module to reinitialize and output the video source signal. It can be understood that when the control execution module issues a restart signal, the reset circuit outputs a reset pulse to the signal acquisition module, clearing the internal state of the signal acquisition module and reinitializing it. After initialization, the signal acquisition module resumes acquiring signals from the video source and re-outputs the video source signal to subsequent modules. The reset circuit can forcibly restore the working state of the signal acquisition module at the hardware level when software control fails, thereby improving the system's self-recovery capability against persistent anomalies. Example

[0039] This embodiment provides an endoscopic surgery display device, including: a display panel; and an endoscopic surgery display device control system as described in Embodiment 2; wherein, the signal output terminal of the endoscopic surgery display device control system is connected to the signal input terminal of the display panel, and is used to provide a video source signal to the display panel. It can be understood that by employing the above-described control system, parameter settings can be customized according to different application requirements, flexibly matching the display panel to adapt to different usage scenarios. This allows the display device to not only provide high-quality display effects but also achieve personalized settings in different usage scenarios, thereby significantly improving overall performance and user experience.
