[0039] Please see Figure 1This utility model provides a surgical exoscope system, including a camera 11, an image processor (not shown in the figure), at least two sets of lighting modules (not shown in the figure), a trolley body 12, a display module 13, and a lighting control unit (not shown in the figure); wherein, the camera 11 is connected to the trolley body 12 via a camera support arm 14; the image processor is installed inside the trolley body 12, and the display module 13 is installed on the outer surface of the trolley body 12, and the image processor is connected to the camera 11 and the display module 13 respectively; each lighting module includes a light source driving circuit and a light source assembly;

[0040] The lighting control unit is used to detect the operating status information of the target lighting module that is currently in operation within the lighting module; the operating status includes voltage data, current data, and forward voltage drop data; the target lighting module is used to illuminate the lesion area;

[0041] The lighting control unit is also used to generate warning information corresponding to the target lighting module when an abnormality is detected in the target lighting module.

[0042] Camera 11 is used to acquire digital signals of the lesion area of ​​the surgical subject and transmit the digital signals of the lesion area to the image processor;

[0043] An image processor is used to process digital signals from the lesion area and transmit the processing results to the display module 13.

[0044] Display module 13 is used to display the processing results.

[0045] Specifically, the surgical exoscopy system described in this application is generally a standalone device. This device can be used to provide illumination during surgery, and to photograph, display, and record the surgical process or lesion area as needed. For surgeries with small lesions and high precision requirements, such as neurosurgery, the surgical exoscopy system described in this application can provide good illumination and magnified display of deep brain tissue, which is a fundamental prerequisite for completing neurosurgical microsurgery. Currently, microsurgery mainly uses two types of products: surgical microscopes and exoscopy systems. This application seeks protection for a surgical exoscopy system.

[0046] The surgical external endoscope system of this application includes a camera 11, an image processor, and a display module 13. The camera 11 is connected to the trolley body 12 via a camera support arm 14. The image processor is installed inside the trolley body 12, and the display module 13 is installed on the outer surface of the trolley body 12. The image processor is connected to both the camera 11 and the display module 13. After the camera 11 acquires digital signals from the lesion area, it transmits the signals to the image processor via a cable in the camera support arm 14 for image processing. After image processing is completed, the video is output to the display module 13 via a port. The display module 13 displays the video, providing clear and magnified three-dimensional and fluorescent images.

[0047] The surgical endoscope system of this application also includes multiple lighting control units. In some preferred embodiments, there may be three lighting control units, each with a different spectrum. Each lighting control unit includes a light source driving circuit and a light source component, with a one-to-one correspondence between the light source driving circuit and the light source component. The light source driving circuit is connected to the light source component, which is preferably an LED device. The light source driving circuit drives the light source component for illumination. This application also includes lighting control units, each connected to a light source driving circuit. In some preferred embodiments, the lighting control units may be controller CPUs (Central Processing Units). The lighting modules are all located inside the trolley body. In some preferred embodiments, the lighting modules are connected to the light-emitting modules in the camera via optical fibers. After the lighting modules output light, it is transmitted to the light-emitting modules in the camera via the optical fibers to illuminate the lesion. In other embodiments, the light-emitting modules can be located on the trolley body as needed, and the location of the light-emitting modules can be determined according to actual requirements.

[0048] Furthermore, some embodiments also include an optical path fusion module, which is connected to each light source component. The optical path fusion module is used to converge the light generated by multiple light source components when multiple light source components are working simultaneously, forming a single light source, and outputting it through an optical fiber output interface.

[0049] The aforementioned lighting control unit is used to detect the working status information of the target lighting module that is currently working in the lighting module. The lighting control unit can collect data from the light source driving circuit of the target lighting module through the ADC (Analog to Digital Converter) port of the CPU, and calculate the working status information of the target lighting module based on the collected data. This application uses existing detection methods to detect the operating status information of the target lighting module, and relevant technicians can choose the required detection method according to actual needs. For example, it can detect whether there is a large change in the forward voltage drop of the light source component. When the forward voltage drop increases abnormally, this is an important signal that the LED light source component is about to fail. Specifically, an increase in the forward voltage drop is generally due to poor electrical connection inside the light source component or cracking between the chip and its negative electrode metallization layer. Therefore, when an abnormal increase in the forward voltage drop is detected, it can be determined that the currently working target lighting module is about to fail, and an early warning can be issued. Alternatively, it can detect the driving current value and driving voltage value of the light source driving circuit. If the driving current and / or driving voltage output of the light source driving circuit is abnormal, it will also cause the lighting module to fail. Therefore, when an abnormal driving current value and / or driving voltage value is detected, it can also be determined that the currently working target lighting module is about to fail, and an early warning can be issued. This application detects the operating status information of the lighting module through the sampling port of the lighting control unit, thereby enabling timely detection of abnormal states before the light is turned off. In summary, this embodiment can collect and detect the working status information of the target lighting module. When an abnormality is detected in the target lighting module, a warning message corresponding to the target lighting module is generated in a timely manner. Relevant technicians can take action based on the warning message, such as activating backup lighting or switching to another lighting module.

[0050] In summary, the external viewing system in this application includes a lighting system with enhanced safety. The lighting control unit collects and detects the working status information of the lighting module, thereby enabling timely handling before the lighting module malfunctions and the lighting goes out, thus avoiding the safety hazards caused by the sudden extinguishing of the light source during surgery.

[0051] It should be noted that the image processor, lighting module, and lighting control unit in this application are all located inside the trolley body. Those skilled in the art will understand that the specific installation and setting methods are common knowledge in the field and will not be elaborated on here. Relevant technicians can install the above modules according to actual needs.

[0052] In some embodiments, the lighting module further includes a forward voltage drop sampling circuit and a current sampling circuit; each lighting module is provided with a forward voltage drop sampling circuit and a current sampling circuit;

[0053] The forward voltage drop sampling circuit includes a voltage drop acquisition point, a voltage divider circuit, and a filtering unit. The output terminal of the light source driving circuit is connected to the input terminal of the voltage divider circuit. The voltage divider circuit is equipped with a voltage drop acquisition point, and the filtering unit is connected in parallel with the voltage divider circuit. The forward voltage drop sampling circuit is used to acquire the voltage data of the target lighting module and send the voltage data to the lighting control unit.

[0054] The current sampling circuit includes a current acquisition point and a current sensor; the current acquisition point and the current sensor are located at the output end of the light source component; the current sampling circuit is used to acquire the current data of the target lighting module and send the current data to the lighting control unit.

[0055] The lighting control unit is also used to calculate the forward voltage drop data based on the voltage data.

[0056] Specifically, Figure 2 This is a circuit diagram of a forward voltage drop sampling module and a current sampling module in one embodiment. In this application, each lighting module is provided with a forward voltage drop sampling circuit and a current sampling circuit. In the diagram, LED represents the aforementioned light source component, R1 and R2 are the aforementioned voltage divider circuits, which are used for voltage division and ADC sampling. In some preferred embodiments, R1 and R2 use high-precision resistors; C1 is a filter unit used to filter out interference; the driver circuit input is the input of the light source driver circuit corresponding to the light source component; ADC1 is the aforementioned voltage drop sampling point, and ADC1 is connected to the lighting module control unit to sample LED voltage data and send the sampled voltage data to the aforementioned lighting control unit.

[0057] In the figure, R3 is the aforementioned current sensor, and ADC2 is the current acquisition point. ADC2 is connected to the ADC port of the aforementioned lighting control unit to sample the LED current data and send the LED current data to the lighting control unit.

[0058] Finally, based on the collected LED voltage and current data, the lighting control unit can calculate the aforementioned forward voltage drop data.

[0059] The forward voltage drop of an LED is V f1 ′=V ADC1 / (R2 / (R1+R2))

[0060] The current value of an LED is I f1 ′=V ADC2 / R3

[0061] As will be understood by those skilled in the art, the above calculations of forward voltage drop and current value are common knowledge in the field.

[0062] In summary, the voltage, current, and forward voltage drop data of the lighting components in each lighting module can be obtained using the calculation method described above. Therefore, based on the voltage, current, and forward voltage drop data—that is, the aforementioned operating status information—it is possible to detect whether the operating target lighting module is experiencing any abnormalities.

[0063] In some embodiments, the control unit is connected to the voltage drop acquisition point and the current acquisition point respectively through preset sampling interfaces:

[0064] The control unit is also used to collect the working status information of the target lighting module through the sampling interface based on a preset sampling interval.

[0065] Specifically, the working status information of the target lighting module can be sampled through the sampling interface according to the preset sampling interval. The sampling interval can be set by relevant technicians according to actual needs, such as 10s.

[0066] In some of these embodiments, the lighting modules have different spectra.

[0067] Specifically, to adapt to different application scenarios, this application can use light source components with different spectra. In some preferred embodiments, three LED light source components can be set, with their spectra being 405nm narrowband light band, white light 400nm-700nm (visible light) band, and 785nm narrowband light band, respectively. In practical applications, the light source component with the required spectrum can be selected according to actual needs.

[0068] In some embodiments, the surgical exoscope system further includes electrical devices, a control panel, and a main control center, wherein the control panel is mounted on the trolley body, and the electrical devices are mounted inside the trolley body;

[0069] The electrical components are connected to the camera, image processor, lighting module, display module, and control console, respectively, and are used to provide electrical power.

[0071] Specifically, Figure 3This is a schematic diagram of a surgical exoscopic system in one embodiment. It includes an electrical device (not shown), a control panel 31, and a main control center. The electrical device is installed inside the trolley body 12 and provides power to various parts of the trolley body 12. The control panel 31 is mounted on the upper surface of the trolley body 12 and can use a touchscreen to receive user input commands, such as recording, light source adjustment, white balance, display mode, taking photos, recording videos, camera arm 14 control, focusing, zooming, image adjustment, dual-mirror combination, user management, patient management, and file management. The main control center can be located inside the control panel 31 or inside the trolley body 12; the specific integration method can be determined by relevant technical personnel according to actual needs. The main control center is connected to the control panel 31 and receives commands received by the control panel 31, controlling the corresponding components based on those commands.

[0072] In some embodiments, the camera includes an optical imaging lens, a digital signal acquisition module, and a light output module, wherein each illumination module is connected to the light output module.

The aforementioned digital signal acquisition module preferably uses a CMOS sensor. In summary, the optical imaging lens is used to perform 3D imaging of the lesion area, and the digital signal acquisition module converts the image signal to obtain the digital signal of the lesion area, which is then transmitted to the image processor. The aforementioned light output module provides the light source output by the illumination module. The illumination module within the trolley body is connected to the light output module via a light guide fiber, and the light source output by the light output module is used to illuminate the lesion area.

[0075] Specifically, the light-emitting module also includes an optical cable, an illumination zoom module, and a reflector. The connection methods between the various modules described above are common knowledge in the art. In summary, through the optical cable, illumination zoom module, and reflector in this embodiment, the size of the light spot, the angle of illumination, etc., can be flexibly adjusted to meet the illumination needs during surgery.

[0076] In some embodiments, the lighting system includes at least two sets of light source driving circuits, each set of light source driving circuits corresponding to a light source component, and all light source components are connected to the light output module through an optical fiber output interface; wherein, the light output module is located inside the camera, and the light source driving circuit, the light source component and the optical fiber output interface are located inside the trolley body, and the optical fiber output interface and the light output module are connected through a light guide fiber.

The diagram uses three LED light source driving circuits and corresponding three LED light source components as an example. The three light source components are fused through a lighting light path fusion module, thereby merging the lighting light output paths and combining them into a single light output port. This allows for the use of a single light guiding medium for light guidance, which is then connected to the light output module via an optical fiber output interface and a light guiding fiber. Furthermore, in addition to the components mentioned above, the lighting system provided in this application also includes conventional components such as an early warning module, a ROM (Read-Only Memory), a clock, and an RTC (Real-Time Clock).

Each lighting module includes a light source driving circuit and a light source component. This application detects the operating status of the target lighting module and generates corresponding warning information when an abnormality is detected. The method for detecting the target lighting module's status includes: firstly, measuring parameters such as current values ​​and forward voltage at different levels when the lighting module is working normally, and then generating a mapping table. In practical applications, the lighting module typically has 1024 levels, meaning 1024 different light source intensities.

[0086] Assuming a normal lighting module operates at a certain setting Pn, its current value is Ifn and its forward voltage is Vfn. When actually operating at setting Pn, the current and voltage values ​​are collected, resulting in a current value Ifn' and a corresponding forward voltage drop of Vfn'. If Vfn' > Vfn*a (where a is a voltage redundancy coefficient, determined based on the performance of different LEDs), then an over-limit value is detected, and an LED malfunction warning is issued. Similarly, if Ifn' > Ifn*b or Ifn' < Ifn*b (where b is a current redundancy coefficient, determined based on the performance of different LEDs), then an over-limit value is detected, and a driver circuit malfunction warning is issued.

[0087] By using the above methods, abnormalities in the lighting module can be detected in a timely manner, and the abnormal state can be dealt with promptly while the lighting is still on, thus ensuring that doctors do not lose the surgical field without preparation and cause safety accidents.
