For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0028] In the field of surgical medicine, computer-aided medical systems have been widely used in minimally invasive laparoscopic and orthopedic surgeries due to their precise operation and minimally invasive characteristics. Please refer to [reference needed]. Figure 1 The diagram shows a schematic of a computer-assisted medical system 10. The computer-assisted medical system 10 includes multiple devices such as a doctor's console 101, a surgical robot 102, and a vision cart 103.

[0029] The doctor's operating table 101 includes a display unit for showing the surgical instruments and environment, an operating control mechanism, and armrests. The display unit has an observation window (also called a stereoscopic display) for the doctor to observe. The movements of the operating control mechanism correspond to the movements of the surgical instruments; by controlling the operating control mechanism, the position of the surgical instruments can be adjusted. The armrests are for supporting the doctor's arms. In addition, the doctor's operating table 101 also includes other control switches that are convenient for the doctor to touch or press with their hands or feet to perform various functions and complete human-computer interaction.

[0030] The surgical robot 102 includes several robotic arms 102a, each comprising several connecting arms. Adjacent connecting arms move relative to each other with specific degrees of freedom, allowing the end effector of the robotic arm 102a to achieve multiple degrees of freedom (e.g., 7 degrees of freedom, depending on the instrument). An instrument actuator is mounted on the end effector of the robotic arm 102a. Surgical instruments or image acquisition devices are detachably mounted on the instrument actuators. Surgical instruments are instruments used to perform surgical procedures, such as electrocautery devices, clamps, and vascular occluders. Image acquisition devices are devices used to acquire images of the surgical site, such as endoscopes, optical cameras, and ultrasound probes. For ease of understanding, the following description uses an endoscope as an example of the image acquisition device; however, it is understood that the image acquisition device in this application can also be of other types.

[0031] The visual trolley 103 includes a display screen, an image processor, etc. The endoscope can acquire images (such as surgical images) and send the acquired images to the image processor, so that the image processor can perform image processing on the images acquired by the endoscope (such as decoding, noise reduction, contrast enhancement, and sharpness improvement). The image processed by the image processor can be displayed through the display screen and display unit.

[0032] During surgery, the doctor typically sits at the operating table 101, while the nurse stands beside the patient facing the vision cart 103. The doctor needs to maintain constant communication with the nurse to ensure the surgery proceeds smoothly. Therefore, the computer-assisted medical system 10 may also include an intercom system, comprising at least two intercom devices 104, respectively positioned on the operating table 101 and the vision cart 103, to enable real-time voice transmission between the doctor and nurse. During the intercom, the intercom device 104 on the operating table 101 captures the doctor's voice while performing the surgery and outputs the nurse's voice on the vision cart 103; the intercom device 104 on the vision cart 103 captures the voice of the nurse assisting in the surgery and outputs the doctor's voice on the operating table 101. Of course, in complex surgeries, multiple surgeons may be involved, and the computer-assisted medical system 10 may also have multiple operating tables 101, each equipped with multiple intercom devices, to support collaborative communication among multiple medical personnel.

[0033] However, current intercom systems face some technical challenges. When the system's status changes, the intercom devices at both ends, being relatively independent and always on, are susceptible to transmission when the status of one device changes. This transmission can cause abnormal noise on the other end. This noise can interfere with communication between medical staff and may also affect the safety and efficiency of surgeries.

[0034] Specifically, the current problems with intercom systems are mainly reflected in the following aspects:

[0035] During the system power-on process, both the doctor's console 101 and the vision cart 103 are powered on simultaneously. However, due to the different time required for the internal system to stabilize from power-on, the intercom devices at both ends also take different times to stabilize. For example, if the intercom device at the doctor's console 101 has already stabilized, while the intercom device at the vision cart 103 has not yet stabilized, once the intercom device at the vision cart 103 stabilizes, the intercom device at the vision cart 103 will suddenly experience a change in audio signal input, which will then generate abnormal noise in the doctor's console 101.

[0036] During the system power-down process, the power-off time of the intercom devices at both ends of the doctor's console 101 and the vision cart 103 cannot be guaranteed to be consistent. For example, if the intercom device at the doctor's console 101 suddenly loses power, the intercom device at the doctor's console 101 will suddenly show a change in audio signal input, which will be transmitted to the vision cart 103. However, the intercom device at the vision cart 103 is not powered off, so abnormal noise will be generated at the vision cart 103 end.

[0037] During the system state switching process, when the intercom system has been working for a long time, some state changes may occur, such as the audio communication line being unplugged and replugged. At this time, it may be necessary to reconfigure the intercom device. During the configuration process, the intercom device may also experience some sudden changes in input signals, resulting in abnormal noise.

[0038] To address the aforementioned problems, this application provides an improved intercom system. This system adds a controller to each intercom device. Based on state change commands from each intercom device, the controller intelligently controls the audio output device of the intercom device to turn on or off, thereby effectively eliminating abnormal noise during the intercom process, improving the audio transmission quality for communication between medical staff, and enhancing surgical efficiency and safety.

[0039] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0040] First, the basic structure of the intercom system according to the embodiments of this application will be described.

[0041] Please refer to Figure 2 The diagram shows a schematic of an intercom system. The intercom system includes two intercom devices 104, each of which includes: an audio acquisition unit 1041, an audio transceiver 1042, an audio output device 1043, and a controller 1044.

[0042] The audio acquisition unit 1041 is used to acquire audio signals, such as the voice of a doctor or nurse. It typically uses a microphone or other audio input device to capture sound, convert it into electrical signals, and send them to the audio transceiver 1042 for further processing and transmission.

[0043] The audio transceiver 1042 is used to send audio signals to other intercom devices and to receive audio signals from other intercom devices. It can be a wireless communication module or a wired communication module, enabling audio signal transmission via wired or wireless means.

[0044] The audio output device 1043 is used to output audio signals from other intercom devices. It may include various audio output devices such as speakers and headphones, which convert the received audio electrical signals into sound so that the user can hear them.

[0045] The controller 1044 is used to detect a first state change command of the intercom device and to acquire a second state change command from other intercom devices, and based on these state change commands, to control the audio output device of the intercom device to turn on or off; wherein, the first state change command indicates a state change event of the intercom device, and the second state change command indicates a state change event of other intercom devices. The controller 1044 may be a microprocessor or various control devices, intelligently detecting and controlling the working state of the intercom device to eliminate abnormal noise during the intercom process.

[0046] To enable the transmission of audio data and the exchange of status change commands between different intercom devices, the audio transceivers and controllers in different intercom devices are connected for communication. In some embodiments, the audio transceivers in different intercom devices can be connected via a dedicated audio bus, and the controllers in different intercom devices can be connected via Ethernet. This utilizes the dedicated audio bus to achieve low-latency and stable transmission of audio data. Simultaneously, transmitting audio signals and status change commands separately reduces interference between signals, ensuring signal clarity and accuracy, and improving signal transmission efficiency and reliability. In other embodiments, the audio transceivers and controllers in different intercom devices can also be connected via the same data transmission line, thereby simplifying system wiring and reducing costs.

[0047] Taking the example of communicating with the visual cart 103 from the doctor's operating table 101, Figure 2The communication process between the intercom devices is as follows: The audio acquisition unit 1041 of the doctor's operating console 101 acquires the sound signal and converts it into an audio signal. Then, the audio transceiver 1042 of the doctor's operating console 101 processes these signals and sends them to the audio transceiver 1042 of the visual cart 103. The audio transceiver 1042 of the visual cart 103 receives the signal and then transmits it to the audio output device 1043 of the visual cart 103, which finally outputs sound so that the nurse can hear the doctor's instructions.

[0048] In addition, to meet the needs of multiple medical staff for collaborative communication, such as Figure 3 As shown, in some embodiments, the intercom system may further include two or more intercom devices 104. When the number of intercom devices 104 exceeds two, different intercom devices 104 can be connected in a cascaded manner. The audio transceiver 1042 of the i-th intercom device 104 is communicatively connected to the audio transceiver 1042 of the (i+1)-th intercom device 104, and the controller 1044 of the i-th intercom device 104 is communicatively connected to the controller 1044 of the (i+1)-th intercom device 104, where i is a positive integer. This cascaded connection method allows the intercom system to be easily and flexibly expanded and adjusted, effectively improving the practicality of the intercom system and its adaptability to medical environments.

[0049] exist Figure 3 In the intercom system shown, the intercom process between adjacent intercom devices is as follows: Figure 2 The communication between non-adjacent intercom devices is consistent with the description in the text, and can be achieved through data forwarding by an intermediate intercom device. For example, in an intercom system consisting of intercom devices 1, 2, and 3, communication between intercom device 3 and intercom device 1 requires data forwarding through intercom device 2. That is, the audio signal collected by the audio acquisition unit of intercom device 3 is first sent to the audio transceiver of intercom device 2 through the audio transceiver of intercom device 3, and then forwarded to the audio transceiver of intercom device 1 through the audio transceiver of intercom device 2 for processing, and vice versa. This process ensures clear and continuous communication even in an environment with multiple intercom devices.

[0050] Next, the specific control process of the controller 1044 in each intercom device 104 will be explained.

[0051] In order to effectively eliminate abnormal noise in the intercom system under various working conditions, the controller 1044 needs to be able to detect and acquire the state change instructions of this intercom device and other intercom devices in different state change events, such as power-on, power-off or state switching events, and provide a precise processing mechanism for different state change instructions to ensure the transmission quality of audio data.

[0052] In handling power-on events, when the controller 1044 detects a first state change command indicating a power-on event for the intercom device, it can first control the audio output device of the intercom device to turn off based on the current first state change command. This is because, in the initial stage of power-on, other intercom devices in the intercom system may not all be powered on yet, and may send unstable audio signals to this intercom device. If the audio output device is on at this time, it will output abnormal noise generated by these unstable audio signals. By turning off the audio output device in advance, the output of abnormal noise can be effectively avoided. Subsequently, the controller 1044 can perform a power-on operation on the intercom device according to the current first state change command and wait for it to complete the power-on. Then, after the controller 1044 has completed the power-on of the intercom device according to the current first state change command, and has received a second state change command from other intercom devices indicating that the power-on of other intercom devices has been completed, the controller 1044 can then control the audio output device of the intercom device to turn on. At this time, since all intercom devices in the intercom system have been powered on and the audio signal transmission is stable, there will be no abnormal noise caused by signal sudden changes.

[0053] In handling power-down events, when the controller 1044 detects a first state change command indicating a power-down event for the intercom device, it can also control the audio output device of the intercom device to shut down based on the current first state change command to prevent noise interference from other intercom devices that have not yet been fully powered down. Afterwards, the controller 1044 can then perform a complete power-down process on the intercom device based on the current first state change command.

[0054] The handling of state switching events is slightly different. The controller 1044 needs to distinguish whether the state switching command comes from this intercom device or other intercom devices, because this is related to whether a state switching operation needs to be performed on this intercom device.

[0055] When controller 1044 detects a first state change command indicating a state switching event for this intercom device, it can also control the audio output device of this intercom device to turn off based on the current first state change command, to avoid abnormal noise interference caused by other intercom devices not yet having fully completed their state switching. Then, controller 1044 performs a state switching operation on this intercom device according to the current first state change command and waits for it to complete the state switching. Finally, after controller 1044 completes the state switching of this intercom device according to the current first state change command and receives a second state change command from other intercom devices indicating that their state switching events are complete, controller 1044 can then control the audio output device of this intercom device to turn on. At this time, since all intercom devices in the intercom system have completed their state switching, the signal transmission is stable, and therefore no abnormal noise caused by signal abrupt changes will occur.

[0056] When the controller 1044 receives a second state change command indicating a state switching event for another intercom device, it can control the audio output device of this intercom device to turn off based on the current second state change command. This is because other intercom devices have not yet completed their state switching and will send unstable audio signals to this intercom device, resulting in abnormal noise. By pre-disabling the audio output device, abnormal noise can be effectively avoided. Conversely, when the controller 1044 receives a second state command indicating a state switching completion event for another intercom device, it can control the audio output device of this intercom device to turn on based on the current second state change command. At this time, other intercom devices have completed their state switching, signal transmission is stable, and noise caused by signal abrupt changes will not occur.

[0057] Furthermore, to ensure that each intercom device 104 in the system can respond promptly to state changes of other intercom devices and adjust its own audio output accordingly, the controller 1044 of each intercom device 104 can also be used to send a third state change instruction to other intercom devices according to at least a portion of a first state change instruction and / or a second state change instruction. This third state change instruction is used to indicate a state change event of the intercom device itself and / or at least a portion of the state change events of other intercom devices.

[0058] When the intercom system includes only two intercom devices 104, the two devices only need to respond to each other's state changes. In this case, for any intercom device 104, its controller 1044 only needs to send a third state change command to the other intercom device 104 according to the first state change command to indicate the state change event of this intercom device.

[0059] For example, when the controller 1044 detects a first state change command indicating a power-on event for the intercom device, and after powering on the intercom device according to the first state change command, it sends a third state change command indicating a power-on completion event for the intercom device to another intercom device, in order to notify the other party that the intercom device has been powered on.

[0060] Alternatively, when the controller 1044 detects a first state change instruction indicating a state switching event for this intercom device, before switching the state of this intercom device according to the first state change instruction, it sends a third state change instruction indicating a state switching event for this intercom device to another intercom device to notify the other party that this intercom device needs to switch its state.

[0061] Alternatively, when the controller 1044 completes the state switch of this intercom device according to the first state change instruction, it sends a third state change instruction to another intercom device indicating that the state switch of this intercom device has been completed, so as to notify the other party that this intercom device has completed the state switch.

[0062] When the intercom system includes two or more intercom devices 104, each intercom device 104 must respond not only to the state changes of intercom devices 104 directly connected to it, but also to the state changes of intercom devices 104 not directly connected to it in the system. In this case, for any intercom device 104, its controller 1044 needs to combine a first state change command and at least a portion of second state change commands to send a third state change command to other intercom devices 104 to indicate the state change event of this intercom device and the state change events of at least a portion of other intercom devices in the system.

[0063] Specifically, in this case, the second state change instruction is a summary of the state change instructions of all other intercom devices in the intercom system besides this intercom device. For example, if this intercom device is the i-th intercom device in the intercom system, where i is an integer greater than or equal to 1 and less than or equal to N, and N is the number of intercom devices in the intercom system; the second state change instruction includes a second state change instruction sent from the (i-1)-th intercom device to this intercom device, used to indicate the state change events of the 1st to the (i-1)-th intercom devices, and a second state change instruction sent from the (i+1)-th intercom device to this intercom device, used to indicate the state change events of the (i+1)-th to the Nth intercom devices.

[0064] At least a portion of the second state change instruction includes a second state change instruction sent from the (i-1)th intercom device to this intercom device and used to indicate state change events of the 1st to (i-1)th intercom devices, or a second state change instruction sent from the (i+1)th intercom device to this intercom device and used to indicate state change events of the (i+1)th to Nth intercom devices.

[0065] Taking an intercom system containing five cascaded intercom devices as an example, the second state change instruction acquired by the third intercom device includes a second state change instruction sent by the second intercom device to indicate the change events of the first to second intercom devices, and a second state change instruction sent by the fourth device to indicate the change events of the fourth to fifth devices.

[0066] In order for the fourth intercom device to be aware of the status changes of the first three intercom devices, the controller of the third intercom device can send a third status change instruction to the fourth intercom device according to the first status change instruction indicating the status change event of the third intercom device and the second status change instruction indicating the status change event of the first and second intercom devices, so as to indicate the status change events of the third intercom device and the first and second intercom devices.

[0067] Alternatively, in order for the second intercom device to be aware of the status changes of the latter three intercom devices, the controller of the third intercom device can send a third status change instruction to the second intercom device based on a first status change instruction indicating a status change event of the current intercom device and a second status change instruction indicating a status change event of the fourth to fifth intercom devices, so as to indicate the status change events of the current intercom device and the fourth to fifth intercom devices.

[0068] Similarly, for each specific state event, for example, when the controller 1044 detects a first state change command indicating a power-on event for the intercom device, and after powering on the intercom device according to the first state change command, it sends a third state change command to other intercom devices indicating a power-on completion event for at least some of the intercom devices, in order to notify the other party that at least some of the intercom devices have been powered on.

[0069] Alternatively, when the controller 1044 detects a first state change instruction indicating a state switching event for the intercom device, before switching the state of the intercom device according to the first state change instruction, it sends a third state change instruction indicating a state switching event for at least some of the intercom devices, to other intercom devices, so as to notify the other party that at least some of the intercom devices need to switch the state.

[0070] Alternatively, when the controller 1044 completes the state switch of the intercom device according to the first state change instruction, it sends a third state change instruction to other intercom devices, indicating that at least some of the intercom devices among the intercom devices have completed the state switch event, so as to notify the other party that at least some of the intercom devices among the intercom devices have completed the state switch.

[0071] In order to obtain a greater output volume and ensure that the audio signal retains sufficient strength and clarity after transmission, in some embodiments, the audio output device 1043 may include a power amplifier 10431 and an audio output unit 10432.

[0072] The power amplifier 10431 can amplify audio signals from other intercom devices to ensure that these signals have sufficient strength before reaching the audio output unit 10432, thereby ensuring the clarity and audibility of the audio signal output.

[0073] The audio signal, amplified by power amplifier 10431, is sent to audio output unit 10432, which converts it into a sound signal and outputs it. Depending on the application, audio output unit 10432 can use different types of audio devices, such as speakers or headphones. Speakers are suitable for public places or large spaces, broadcasting sound to the surrounding environment; while headphones are suitable for situations requiring private listening, directly transmitting audio signals to the user.

[0074] To further improve the transmission quality of audio signals, in some embodiments, the intercom device 104 may also include a codec 1045.

[0075] The codec 1045 converts the analog audio signal acquired by the audio acquisition unit 1041 into a digital audio signal and sends it to the audio transceiver 1042 for transmission. Digital signals have stronger anti-interference capabilities than analog signals and can maintain higher signal quality during long-distance transmission. Therefore, the conversion by the codec 1045 effectively reduces signal loss and improves signal transmission efficiency. When receiving audio signals from other intercom devices, the codec 1045 performs the reverse conversion process, converting the digital audio signal back into an analog audio signal and sending it to the power amplifier 10431. This allows the power amplifier 10431 and the audio output unit 10432 to process and output the signal, ensuring that the received audio signal maintains its original sound quality and clarity in the final output.

[0076] During operation, the codec 1045 can also be configured by the controller 1044 to adapt to specific transmission requirements and environmental conditions. For example, the controller 1044 can adjust the sampling rate and quantization bit depth of the codec 1045 according to the characteristics of the audio signal to achieve optimal audio quality; or, the controller 1044 can adjust the encoding and decoding algorithm according to network conditions and transmission distance to optimize transmission efficiency and reduce latency, etc.

[0077] In order to further optimize the processing performance of audio signals, in some embodiments, the intercom device 104 may also include a digital signal processor 1046.

[0078] The digital signal processor 1046 can perform further signal processing on the digital audio signal converted by the codec 1045, such as noise suppression, echo cancellation, and automatic gain control, to optimize sound quality and improve signal transmission efficiency. The processed signal is sent to the audio transceiver 1042 for transmission to other intercom devices. When the audio transceiver 1042 receives audio signals from other intercom devices, the digital signal processor 1046 can also perform the same signal processing on these audio signals before sending the processed signal to the codec 1045, and finally output by the power amplifier 10431 and the audio output unit 10432.

[0079] During operation, the digital signal processor 1046 can also be configured by the controller 1044 to adapt to different processing performance requirements of the audio signal. For example, the controller 1044 can set the performance parameters of the digital signal processor 1046 to enhance the clarity of the audio signal or reduce the level of background noise, thereby providing a better audio experience.

[0080] Based on the aforementioned embodiments, the controller 1044 controls the audio output device 1043 specifically by controlling the power amplifier 10431. Since the power amplifier 10431 is primarily responsible for amplifying the audio signal to a level sufficient to drive the audio output device 10432, without its amplification, the audio signal would not reach sufficient strength, thus preventing effective output. Therefore, by controlling the power amplifier 10431 to turn it on and off, the controller 1044 effectively controls the overall operating state of the audio output device 1043.

[0081] To enable more flexible control of the power amplifier 10431, in some embodiments, the digital signal processor 1046 may include several input / output ports, and the controller 1044 controls the power amplifier 10431 of the intercom device to turn on or off by configuring the input / output ports.

[0082] Specifically, in the control process, for example, during power-on, after the controller 1044 detects the power-on command of the intercom device, it can first control the power amplifier 10431 to shut down by configuring the input / output ports of the digital signal processor 1046, ensuring that the audio output device 10432 does not output sound. This process can be achieved by setting the control pin of the power amplifier 10431 to a high-impedance state, which allows the power amplifier 10431 to remain shut down by externally provided pull-up or pull-down resistors. Subsequently, the controller 1044 configures the codec 1045, the digital signal processor 1046, and the audio transceiver 1042 according to the actual power-on requirements, i.e., performs the actual power-on operation. After power-on is completed, the controller 1044 informs other intercom devices via network communication that the intercom device has been powered on. At this time, the controller 1044 again controls the power amplifier 10431 to turn on by configuring the input / output ports of the digital signal processor 1046, i.e., opening the intercom voice channel and allowing the audio signal to be output normally, thereby effectively avoiding abnormal noise during the power-on process of the intercom system.

[0083] During the power-down process, after the controller 1044 detects the power-down command of the intercom device, it can first control the power amplifier 10431 to turn off by configuring the input and output ports of the digital signal processor 1046, ensuring that the audio output device 10432 will not output sound, and then cut off the power supply of the intercom device, thereby effectively avoiding abnormal noise during the power-down process of the intercom system.

[0084] During the state switching process, taking the state switching of this intercom device as an example, after the controller 1044 detects the state switching command of this intercom device, it can notify other intercom devices via network communication that this intercom device needs to switch states. At this time, the controller 1044 can first control the power amplifier 10431 to turn off by configuring the input / output ports of the digital signal processor 1046, ensuring that the audio output device 10432 will not output sound. Subsequently, the controller 1044 reconfigures the codec 1045, digital signal processor 1046, audio transceiver 1042, or the master / slave device of the intercom according to actual needs, that is, performs the state switching operation. After the state switching is completed, the controller 1044 notifies other intercom devices via network communication that this intercom device has completed the state switching. At this time, the controller 1044 again controls the power amplifier 10431 to turn on by configuring the input / output ports of the digital signal processor 1046, that is, opens the intercom voice channel, allowing the audio signal to be output normally, thereby effectively avoiding abnormal noise during the state switching process of the intercom system.

[0085] Please refer to the above embodiments. Figure 4The diagram illustrates the structure of yet another intercom system. This intercom system includes two intercom devices 104, each comprising: an audio acquisition unit 1041, an audio transceiver 1042, a power amplifier 10431, an audio output unit 10432, a controller 1044, a codec 1045, and a digital signal processor 1046. The audio transceivers 1042 in different intercom devices are connected via a dedicated audio bus, and the controllers 1044 in different intercom devices are connected via Ethernet.

[0086] Taking the use of the vision cart 103 to communicate with the doctor's operating table 101 as an example, Figure 4 The communication process between the two intercom devices is as follows:

[0087] The audio acquisition unit 1041 of the vision cart 103 acquires sound signals and converts them into audio signals, which are then transmitted to the codec 1045 of the vision cart 103. The codec 1045 converts the audio signals into digital audio signals and sends them to the digital signal processor 1046 of the vision cart 103. The digital signal processor 1046 processes the digital audio signals and sends them to the audio transceiver 1042 of the vision cart 103. The audio transceiver 1042 encodes the acquired audio signals and transmits the encoded signals via a dedicated audio bus. The audio signal is sent to the audio transceiver 1042 of the doctor's operating console 101. The audio transceiver 1042 of the doctor's operating console 101 decodes the received audio signal and sends it to the digital signal processor 1046 of the doctor's operating console 101 for signal processing. Then it is sent to the codec 1045 of the doctor's operating console 101 to be converted into an analog audio signal and sent to the power amplifier 10431 of the doctor's operating console 101 for amplification. Finally, the amplified audio signal is output through the audio output unit 10432 so that the user of the doctor's operating console can clearly hear the voice of the user of the vision cart.
