[0050] As described in the background, most endoscope systems often use high-power light source assemblies to cooperate with cameras for illumination, however, long-term use increases the surface temperature of the light source assembly, reduces the service life of the light source assembly, and even burns the light source assembly.

[0051] Based on the above problems, the utility model provides a light source adjustment scheme to protect the light source assembly in the endoscope system.

[0052] The endoscope scheme will be described in detail below.

[0053] Please refer to Figure 1A , Figure 1A A structure diagram of an endoscope system in this embodiment is shown. The endoscope system 10 in this embodiment includes a light source assembly 101 and a light source control device 100. The light source control device can be used to adjust the working state of the light source assembly. Please refer to Figure 1B , Figure 1B An implementation of the endoscope system in this embodiment can also include an insertion section 6, an operating handle 5, an image processor 3 for endoscope, and a display 1. The light source assembly 101 can be placed in the tip portion of the insertion section 6; the light source control device 100 can be placed in the operating handle 5 or the image processor 3.

One end (the tip portion) of the insertion section 6 can be inserted into the inside of a living body.

[0055] In this embodiment, the image processor 3 can be a one-piece portable processor, and can also include a cold light source. The present application does not limit the number and form of the image processor.

[0056] It should be noted that the above Figure 1B is only an implementation example of the endoscope system and does not constitute a limitation on the endoscope system. The endoscope system can include more or fewer components than those shown in the figure, or combine certain components, or different components.

[0057] Specifically, on the basis of Figure 1A , please refer to Figure 2 , Figure 2 A structure diagram of a light source control device in this embodiment is shown. The light source control device 100 includes a control module 102, a storage module 103, and a temperature monitoring module 104. The control module 102 is connected to the light source assembly 101, the storage module 103, and the temperature monitoring module 104. In this embodiment, the temperature monitoring module 104 can be arranged on the surface or near the light source assembly 101.

[0058] The temperature monitoring module is used to monitor the real-time temperature of the light source assembly or to monitor the temperature of the light source assembly at regular intervals. The control module can be used to send the monitored temperature to the storage module. When the monitored temperature exceeds a first preset threshold or a command to turn off the light source assembly is received, the control module sends a first control signal to the light source assembly to cut off the power supply of the light source assembly. Of course, in some examples, the first control signal for cutting off the power supply of the light source assembly can also be triggered by the operator by operating the control key for turning off the light source assembly or the control key for turning off the endoscope system.

[0059] The storage module is configured to record the brightness information of the light source assembly, and send the brightness information before power failure to the control module after the light source assembly is powered on, so that the light source assembly uses the brightness information before power failure.

[0060] In this embodiment, the storage module is configured to record the working brightness information of the light source assembly in real time, so that the working brightness information before power failure of the light source assembly can be directly called after the light source assembly is powered on, and the use convenience of the light source control device is improved.

[0061] Therefore, the embodiment provides a light source control device based on the control module, the storage module and the temperature monitoring module, which can monitor the temperature of the LED lamp in real time or at a fixed time, and adjust the working state of the LED lamp when the temperature exceeds a first preset threshold, thereby overcoming the technical problem of excessively high temperature of the LED in the endoscope system, and protecting the light source assembly in the endoscope system.

[0062] Please refer to Figure 3 , Figure 3 FIG. 1 shows a structural schematic diagram of the light source assembly in this embodiment. The light source assembly 101 in this embodiment includes an LED lamp 201 and a driving module 202. The driving module 202 is connected with the LED lamp 201 and the control module 102. The temperature monitoring module 104 is arranged in the environment of the LED lamp 201.

[0063] The driving module includes a plurality of working states. Each working state corresponds to a different output current of the driving module, so as to adjust the brightness information of the LED lamp by changing the input current of the LED lamp.

[0064] For any working state, the control module sends a second control signal to the driving module. The driving module adjusts the input current of the LED lamp to a corresponding value according to the second control signal, so as to adjust the brightness information of the LED lamp.

[0065] It should be noted that the LED lamp in this embodiment is used for illuminating the endoscope, and can be adjusted by the control module to provide different degrees of brightness information for the endoscope. When the endoscope includes a camera, the LED lamp can be arranged on any side of the camera. When the monitored temperature exceeds the first preset threshold, the control module sends a first control signal to the light source assembly to cut off the power supply of the light source assembly. At this time, the endoscope can be illuminated only by the light emitted by the camera itself.

[0066] In this embodiment, the control module can send a second control signal to the driving module to adjust the output current of the driving module, and further adjust the brightness information of the LED lamp. At this time, the storage module can also record the output current of the driving module or the corresponding LED lamp current gear, so that when the light source assembly is powered on, the output current value or the LED lamp current gear recorded above can be called to adjust the brightness information of the LED lamp to the last used state.

[0067] In this embodiment, the structure or arrangement of the LED lamp is not limited, and can be composed of different numbers of LEDs as long as it can illuminate the endoscope.

The second end (negative end) of the second light emitting diode LED2 is connected to the feedback end (FB end) of the driving module and the first end of the first resistor R22. The second end of the first resistor R22 is grounded.

[0068] It should be noted that the embodiment does not limit the way the control module adjusts the output current of the driving module. In one possible implementation, the control module can output a PWM signal with different duty cycles, such as a square wave signal, to the driving module, and further adjust the driving module to output different current signals or voltage signals, and further change the brightness information of the LED lamp.

[0069] For reference Figure 5 , Figure 5A circuit schematic of the driving module in the embodiment is shown; the driving module 202 comprises a driving chip U2, a first transistor Q2, a second transistor Q3 and a second peripheral circuit, wherein the second peripheral circuit comprises a fourth resistor R3; wherein the control end (B pole-base) of the first transistor Q2 is connected with the control module 102, so as to receive the first control signal sent by the control module when the monitored temperature exceeds the first preset threshold, and then cut off the power supply of the light source assembly; the control end of the first transistor Q2 is also connected with the first end (E pole-emitter) of the first transistor Q2 through the fourth resistor R3 and grounded; the second end (C pole-collector) of the first transistor Q2 is connected with the control end (G pole-gate) of the second transistor Q3, and the first end (S pole-source) of the second transistor Q3 is connected with a 3.3V power supply; the second end (D pole-drain) of the second transistor Q3 is connected with the input end of the driving chip U2; wherein the control module 102 is also connected with the enable end of the driving chip U2, so as to send different PWM signals to the enable end of the driving chip U2 to adjust the output current of the driving module.

[0070] Please continue to refer to Figure 5 In order to ensure the stability of the light source assembly, the second peripheral circuit in the embodiment further comprises a fifth resistor R4, a sixth resistor R5 and a filtering assembly 2021, the first end of the fifth resistor R4 is connected with the control module 102, the second end of the fifth resistor R4 is connected with the control end of the first transistor Q2, the first end of the sixth resistor R5 is connected with a 3.3V power supply, and the second end of the sixth resistor R5 is connected with the first end (S pole-source) of the second transistor Q3; the second end (D pole-drain) of the second transistor Q3 is connected with the input end of the driving chip U2 through the filtering assembly 2021.

[0072] In another possible implementation manner, a plurality of control buttons can also be provided, and each control button is connected with an output port of the control module to correspond to the control state of different LED lamps, for example, three control buttons can be included, and the three control buttons are connected with different output ports of the control module, for example, LED lamp on-off control, LED lamp brightness increase control and LED lamp brightness decrease control can be realized respectively.

[0073] In the embodiment, the temperature monitoring module needs to monitor the temperature of the LED lamp, and can be arranged on or near the surface of the LED lamp. In order to ensure the integration of the light source control device, the space for arranging the temperature monitoring module is limited. In a possible implementation, the temperature monitoring module can be a thermistor, which can be arranged on the surface of the LED lamp, for example, the heat sink of the LED lamp, by a simple method such as adhesive, thereby reducing the volume and wiring of the light source control device. In a possible implementation, the temperature monitoring module can use a temperature sensor NTC, which is packaged with a thermistor with a length of 0.5 mm, a width of 0.25 mm, and a resistance of 10KΩ. In the embodiment, when the surface temperature of the light source assembly is too high, the analog voltage of the temperature sensor NTC will change, so that the control module can obtain the temperature.

[0074] In order to realize the monitoring and timeliness of the light source control device, that is, when the monitored temperature exceeds the first preset threshold, the user or the monitoring platform can be fed back in time to warn that the temperature of the current light source assembly is too high. In a possible implementation, please refer to Figure 6 , Figure 6 Another structural schematic diagram of the light source control device in the embodiment is shown, and the light source control device 100 further includes an alarm module 105 connected with the control module 102.

[0075] When the monitored temperature exceeds the first preset threshold, the control module sends a first control signal to the light source assembly to cut off the power supply of the light source assembly, and simultaneously sends a third control signal to the alarm module to drive the alarm module to alarm.

[0076] The embodiment does not limit the implementation manner of the alarm module, and in a possible implementation, the alarm module can include a buzzer assembly and / or a light alarm assembly and / or an audible and visual alarm assembly.

[0079] Similarly to the previous embodiment, in order to realize the monitoring and timeliness of the light source control device, that is, to monitor the current temperature data in real time and feedback to the user or monitoring platform in time, so that the user can call the corresponding data and adjust the parameters of the light source control device, such as the first preset threshold. In one possible implementation, please refer to Figure 8 , Figure 8 Another structural schematic diagram of the light source control device in the embodiment is shown, the light source control device 100 further includes a display module 106, the display module 106 is connected with the control module 102, for displaying the monitored temperature, that is, the real-time temperature of the current light source assembly. In some examples, the display module 106 can be a display 1 of the display 1, and the temperature of the light source assembly is displayed on the screen of the display 1. Figure 1A

[0080] In order to reduce the volume of the corresponding light source control device, the display module can be integrally arranged on the control module.

[0081] Since the light source control device in the embodiment includes multiple modules or assemblies, different configurations of input power are required, in order to improve the integration of the light source control device, please refer to Figure 9 , Figure 9 Another structural schematic diagram of the light source control device in the embodiment is shown, the light source control device 100 further includes a power module 107, the power module 107 includes a power supply unit 301 and at least two voltage conversion units 302. The output end of the power supply unit 301 is connected with the input end of each voltage conversion unit 302, and the output end of each voltage conversion unit 302 is respectively connected with the control module 102 and the display module 106, so as to supply power to the control module 102 and the display module 106.

[0082] ​When the control module needs a supply voltage of 3.3V and the display module needs a supply voltage of 5V, at least two voltage conversion units can be included to directly convert the output voltage of the power supply unit to 3.3V and 5V. In another possible implementation, assuming that the first voltage conversion unit is used to convert the output voltage of the power supply unit to 5V and the second voltage conversion unit is used to convert the output voltage of the power supply unit to 3.3V, to ensure voltage stability and safety of the power supply module, the first voltage conversion unit can be connected in series with the second voltage conversion unit, that is, the input end of the first voltage conversion unit is connected with the output end of the power supply unit, and the output end of the first voltage conversion unit can be connected with the input end of the second voltage conversion unit and the supply end of the display module.

[0083] In this embodiment, the storage module is provided, which can be used to store real-time brightness information and obtain corresponding ambient temperature, so that the control module adjusts the first preset threshold. In a possible implementation, please refer to Figure 10 , Figure 10 Another structural schematic diagram of the light source control device in this embodiment is shown, the temperature monitoring module 104 includes a first temperature unit 401 and a second temperature unit 402, both of which are connected with the control module 102.

[0084] The first temperature unit is used to monitor the monitored temperature of the light source assembly. The second temperature unit is used to monitor the ambient temperature of the light source control device. The control module is further used to send the ambient temperature to the storage module to store the ambient temperature.

[0085] When the difference between the monitored temperature and the ambient temperature is higher than the second preset threshold, the control module sends a third control signal to the alarm module to drive the alarm module to alarm.

[0086] In this embodiment, when the difference between the monitored temperature and the ambient temperature does not satisfy the second preset threshold, that is, there is a large temperature difference between the current ambient temperature and the monitored temperature, in addition to driving the alarm module to alarm, the control module can also calibrate the output value of the first temperature unit by using the ambient temperature. For example, the monitored values corresponding to different ambient temperatures and meeting the correct temperature range can be pre-stored in the storage module. When the difference between the monitored temperature and the ambient temperature does not satisfy the second preset threshold, the control module can call the monitored value corresponding to the current ambient temperature from the storage module, and take the average value between the current ambient temperature and the corresponding monitored value as the calibrated monitored temperature.

[0087] It should be noted that this embodiment does not show the judgment method of the above-mentioned temperature calibration, as long as the above-mentioned calibration can be realized and can be integrated into the control module.
