During the use of endoscope equipment, the endoscope cold light source provides key lighting for endoscopic examination and surgery, enabling the endoscope equipment to obtain clear and detailed images. In addition, the endoscope cold light source usually needs to emit light beams of different bands to meet the different observation needs of users.

[0070] In the actual operation stage of endoscopic equipment inspection or surgery, dynamic video is basically used to assist medical personnel in operation. After the medical personnel operate the endoscope equipment into the human body, the medical personnel select the required lighting mode on the endoscope cold light source, so that the endoscope cold light source emits a corresponding light beam to illuminate the human tissue, and the image of the human body is collected and displayed through the camera on the endoscope equipment.

[0071] Figure 1 A structural schematic diagram of an endoscope device in an embodiment of the present application is exemplarily shown, wherein the endoscope device includes a cold light source, a camera assembly and a display.

[0075] Cold light sources can be used to provide illumination for endoscopes during endoscopic examinations and surgeries; their key components usually include: a cold light source host, a light guide, a communication port, and a cold light source light output interface.

[0076] It should be understood that Figure 1 The schematic diagram of the structure of the endoscope device shown is only an example, and the endoscope device may have more Figure 1 The more or less components shown in the figure can be combined with two or more components, or can have different component configurations. The various components shown in the figure can be implemented in hardware, software, or a combination of hardware and software including one or more signal processing and / or application specific integrated circuits.

[0077] Many different implementations or examples are provided above to implement different structures of the present application. In order to simplify the content of the embodiments of the present application, only the components and settings of specific examples are described above. Of course, they are only examples, and the purpose is not to limit the present application.

[0078] At least two types of light source components in the embodiment of the present application may be a wide-band type light source component and a narrow-band type light source component. A wide band generally has a larger wavelength range, for example, a wavelength range greater than 100 nanometers belongs to a wide band, for example, a wide band may be a band of 400nm-700nm. A narrow band generally has a smaller wavelength range, for example, a wavelength range less than 50 nanometers belongs to a narrow band, for example, a narrow band may be 500nm.

[0079] Exemplarily, in the embodiments of the present application, the wide-band type light source component may be an LED component, and the narrow-band type light source component may be a laser component.

[0080] based on Figure 1 The schematic diagram of the structure of the endoscope device shown in the figure, the schematic diagram of the structure of an endoscope cold light source in the embodiment of the present application Figure 1 .like Figure 2 As shown, the cold light source host 200 may include a control unit 201 , an LED component 202 , a laser component 203 , a first light combining component 204 , a first light combining component 205 , a second light combining component 206 , a filter module 207 , a display 208 and a light output port 209 .

[0081] Among them, the first light combining component 204 is a light combining component corresponding to the LED component 202 , and the first light combining component 205 is a light combining component corresponding to the laser component 203 .

[0082] In an embodiment of the present application, the display is used to display controls corresponding to multiple lighting modes in a display interface, and different lighting modes are set according to the tissue type and lesion type of the detection site.

[0083] A control unit is used to respond to a user's operation of selecting a target lighting mode based on a control trigger, determine at least one target light source component that matches the target lighting mode from at least two types of light source components, and at least one target light source in each target light source component; and control at least one target light source to emit light.

[0084] The first light combining component is used to combine the light emitted by the corresponding multiple target light sources into a first light beam.

[0085] At least one second light combining component is used to combine first light beams emitted by different types of target light source components into a second light beam.

[0086] The filter module is used to filter the first light beam or the second light beam to obtain a target light beam for irradiating the detection part.

[0087] Exemplarily, the multiple illumination modes in the embodiments of the present application may include shallow mucosa illumination mode A, shallow mucosa illumination mode B, deep mucosa illumination mode and fluorescence mode, etc., and the present application does not impose any limitation on this.

[0088] like Figure 3 FIG. 1 is a schematic diagram of a display interface of a cold light source host according to an embodiment of the present application. The display interface includes controls corresponding to multiple illumination modes, and the user selects a target illumination mode from the multiple controls in the display interface, and the control unit in the cold light source host determines the target illumination mode.

[0089] In implementation, the cold light source host displays multiple lighting modes on the display interface. For example, Figure 3 In the figure, the illumination modes displayed include superficial mucosal illumination mode A, superficial mucosal illumination mode B and fluorescence mode.

[0090] In the embodiment of the present application, different illumination modes are pre-set according to the detection type and the location of the lesion at the detection site.

[0091] In the embodiment of the present application, the detection type includes a first light receiving type and a second light receiving type, and the luminous object corresponding to the first light receiving type is different from the luminous object corresponding to the second light receiving type. The luminous object corresponding to the received light under the first light receiving type is the cold light source of the endoscope, and the luminous object corresponding to the received light under the second light receiving type is the detection part.

[0092] That is, after the cold light source of the endoscope emits a light beam, it is used to receive light reflected by the detection site under the first light receiving type, and is used to receive light emitted by the detection site under the second light receiving type.

[0093] During implementation, the detection part is irradiated by the light beam emitted by the cold light source of the endoscope, and emits light after being stimulated by the light beam.

[0094] It should be noted that the light emitted from the detection site includes the light emitted by the tissue in the detection site, or the light emitted by the dye in the detection site.

[0095] In the embodiment of the present application, the lesion location of the detection site includes the superficial mucosa of the detection site, the deep mucosa of the detection site, blood vessels, tumors and other locations.

[0096] For example, the superficial mucosal illumination mode A is used for observing the superficial mucosa of the human body; the superficial mucosal illumination mode B is used for autofluorescence illumination and observation of the superficial mucosa of the human body; the fluorescence illumination mode is used for fluorescence imaging and for ICG, i.e., indocyanine green, color development.

[0097] Among them, the fluorescent illumination mode can be used for blood vessels.

[0098] In the embodiment of the present application, the cold light source host emits different light beams in different illumination modes. For example, the cold light source host uses white light for illumination in white light mode; uses 405nm laser and white light for alternating sequential illumination in shallow mucosal illumination mode A; uses 405nm laser and white light for illumination in shallow mucosal illumination mode B, and uses 540nm narrowband filter in combination; uses 785nm laser and white light for sequential illumination in fluorescence mode.

[0099] like Figure 4 As shown, the structure of an endoscope cold light source in the embodiment of the present application is schematically shown in FIG. Figure 2 .in, Figure 4 The intermediate cold light source host includes a light source module 401 , a power module 402 and a control drive module 403 .

[0100] It should be noted that the control unit in this application is Figure 4 The control driving module 403 in.

[0101] Among them, in the cold light source system, the light source module 401 is the main working module, generating various spectral outputs; the power module 402 provides energy for the light source system; the control drive module 403 provides logic control for the light source system and provides drive for each light source and motor, etc.

[0102] The light source module 401 in the present application includes at least two types of light source components, a first light combining component corresponding to each light source component, at least one second light combining component, and a filter module. Each type of light source component includes multiple light sources.

[0103] It should be noted that each light source is used to emit light of a fixed wavelength, and the present application does not limit the number of light sources used and the wavelength parameters of the emitted light beams.

[0104] In the embodiment of the present application, at least two types of light source components include an LED component and a laser component; the first light combining component corresponding to the LED component is a first fusion filter, and the first light combining component corresponding to the laser component is an all-in-one optical fiber bundle; the second light combining component is a second fusion filter.

[0105] It should be noted that, in the embodiment of the present application, the first fusion filter and the second fusion filter may be the same or different.

[0106] In implementation, the control unit determines at least one target light source assembly from at least two types of light source assemblies and at least one target light source in each target light source assembly based on the mapping relationship between the type of light source assembly and the light source and the illumination mode.

[0107] against Figure 4 The light source module 401 in the embodiment of the present application is a schematic diagram of a light source module structure. Figure 1 ,like Figure 5 As shown. Take the LED components including visible light source, red light source and UV light source as an example, Figure 5 The components include: 1. visible light LED module (visible light source in this solution); 2. red light LED module (red light source in this solution); 3. UV (Ultraviolet) light LED module (UV light source in this solution); 4. coupled laser module; 5.

[0108] 4. The coupled laser module includes: 4.1 coupled laser (laser component in this solution), 4.2 all-in-one optical fiber bundle, and 4.3 coupled output optical module.

[0109] 14. The active heat dissipation module (the first heat dissipation module in this solution) includes: 14.1 a heat dissipation fan; 14.2 a heat sink; 14.3 a heat pipe; 15. a fixing plate.

[0110] 16. The passive heat dissipation module (the second heat dissipation module in this solution) includes: 16.1 heat dissipation fins; 16.2 heat conduction plate, etc.

[0111] Among them, 5. X-type fusion filter 1 is the first light combining component corresponding to the LED component in this solution. 9. Fusion filter 2 is the second light combining component in this solution.

[0112] It should be noted that the 4.1 coupled laser in the embodiment of the present application includes multiple laser light sources, and different laser light sources are used to emit light of different wavelength bands.

[0113] like Figure 6 As shown, a flow chart of a control unit controlling a light source module in an embodiment of the present application, the specific steps are as follows:

[0114] Step S601: In response to a user's operation of selecting a target lighting mode based on a control trigger, a control unit determines at least one target light source component matching the target lighting mode and at least one target light source in each target light source component from at least two types of light source components.

[0115] Step S602: The control unit controls at least one target light source to emit light.

[0116] Under the control of the control unit, the embodiment of the present application can control at least one light source in the LED component to emit light, and / or control at least one light source in the laser component to emit light.

[0117] In the embodiment of the present application, if multiple light sources in the LED assembly emit light, the multiple light beams are combined through the X-type fusion filter, and the X-type fusion filter reflects or projects the first light beam after the light combination, converges through 6. Converging lens 1, and then transmits through 9. fusion filter 2 to enter 12. output light module. If one light source in the LED assembly emits light, the first light beam is reflected or projected through the X-type fusion filter, converges through 6. Converging lens 1, and then transmits through 9. fusion filter 2 to enter 12. output light module.

[0118] Taking controlling at least one light source in an LED assembly to emit light as an example, based on Figure 5 , a light combination diagram of the present application embodiment Figure 1 ,like Figure 7 As shown. Taking the control of each light source in the LED assembly to emit light as an example, the light is synthesized into a first light beam through 5.X type fusion filter, the first light beam is converged through 6. convergence lens, the first light beam is projected through 9. fusion filter through the filter module, and then output from the light output port in the output light module. The filter module filters the first light beam corresponding to the LED assembly.

[0119] It should be noted that 5. The X-type fusion filter can be arranged at the intersection of the light propagation paths corresponding to each light source in the LED assembly; 6. The converging lens is arranged on the light propagation path of the first light beam; 9. The fusion filter can be arranged at the light output port in the output light module, with an angle of a first angle between the light output port and the light output port, and is arranged on the propagation path of the first light beam, with an angle of a second angle between the light propagation path of the first light beam.

[0120] For example, the first angle and the second angle may both be 45°.

[0121] Optionally, the first light beam converged by the converging lens 1 at 6 can also be reflected by the fusion filter 2 at 9 to enter the optical power detector at 10.

[0122] In the embodiment of the present application, if multiple light sources in the laser assembly emit light, the multiple light beams are combined through the all-in-one optical fiber bundle, the first light beam is reflected by the 7. reflector, and then converged by the 8. converging lens 2, and the converged first light beam is reflected by the 9. fusion filter 2 into the 12. output optical module. If one light source in the laser assembly emits light, the first light beam output by the all-in-one optical fiber bundle is reflected by the 7. reflector, and then converged by the 8. converging lens 2, and the converged first light beam is reflected by the 9. fusion filter 2 into the 12. output optical module.

[0123] Taking controlling at least one light source in a laser assembly to emit light as an example, based on Figure 5 , a light combination diagram of the present application embodiment Figure 2 ,like Figure 8 As shown. Taking the control of each light source in the laser assembly to emit light as an example, the light is combined into a first light beam through 4.2 all-in-one optical fiber bundles, the first light beam is reflected by 7. reflector, and then converged by 8. convergence lens, the first light beam is reflected by 9. fusion filter, passes through the filter module, and is output from the light output port in the output light module. The first light beam corresponding to the laser assembly is filtered by the filter module.

[0124] It should be noted that the 7. reflector in the embodiment of the present application is used to adjust the light propagation path of the first light beam corresponding to the laser assembly. For example, after adjustment, the light propagation path of the first light beam corresponding to the laser assembly includes 9. a fusion filter. 8. a converging lens is disposed on the light propagation path of the first light beam corresponding to the laser assembly.

[0125] Optionally, the converged first light beam can also be transmitted through 9. fusion filter 2 and enter 10. optical power detector.

[0126] Taking controlling at least one light source in a laser assembly to emit light and controlling at least one light source in an LED assembly as an example, based on Figure 5, a light combination diagram of the present application embodiment Figure 3 ,like Fig. 9 As shown. 9. The fusion filter merges the first light beam corresponding to the LED component and the first light beam corresponding to the laser component into a second light beam, and the second light beam passes through the filter module and is output from the light output port in the output light module. The filter module filters the second light beams corresponding to the two types of components.

[0127] In the embodiment of the present application, no matter each light source emits light individually or after light is combined, it will enter 10. The optical power detector forms feedback. If the optical power is too small, the control unit will control the light emitter to increase the light output, otherwise, the light output will be reduced.

[0128] against Figure 5 The structure of the light source module shown is shown in FIG. Figure 1 Schematic diagram of a light source module of a second viewing angle in an embodiment of the present application Figure 2 ,like Fig.10 shown.

[0129] In an embodiment of the present application, the endoscope cold light source may further include a temperature sensor, which is in contact with the coupling laser in the laser assembly and is used to obtain the temperature of the coupling laser.

[0130] The control unit is further used to control at least one cooling fan to dissipate heat when it is determined based on the temperature of the coupling laser that the cooling condition is met.

[0131] Optionally, in the embodiment of the present application, the first heat dissipation module further includes a heat pipe and a heat sink, one end of the heat pipe is connected to the light source assembly, and the other end is connected to the heat sink. The fan surface of the heat dissipation fan faces the heat sink. The heat generated by the light source assembly is transferred to the heat sink through the heat pipe, and when the heat dissipation fan is running, air is blown or drawn toward the heat sink to achieve active heat dissipation.

[0132] In the embodiment of the present application, the LED assembly includes a first light source and a second light source, and the maximum temperature threshold corresponding to the first light source is lower than the maximum temperature threshold corresponding to the second light source.

[0133] That is to say, the first light source is a light source with a relatively high temperature requirement, and the second light source is a light source with a relatively low temperature requirement.

[0134] In the embodiment of the present application, one end of the heat pipe in the first heat dissipation module can be connected to the first light source, and the other end can be connected to the heat sink.

[0135] It should be noted that the embodiment of the present application utilizes heat pipes to concentrate the active heat dissipation modules (first heat dissipation modules) as much as possible, thereby optimizing the layout and reducing the overall volume.

[0136] Optionally, the second heat dissipation module in the embodiment of the present application includes a heat conducting plate and heat dissipation fins, one end of the heat conducting plate contacts at least one light source in the LED assembly, and the other end contacts the heat dissipation fins. The second heat dissipation module is used to conduct heat generated by at least one light source through the heat conducting plate and the heat dissipation fins.

[0137] In the embodiment of the present application, one end of the heat conducting plate in the second heat dissipation group can be connected to the second light source, and the other end can be connected to the heat dissipation fins.

[0138] The heat of the second light source is conducted to the heat dissipation fins through the heat conduction plate, and the heat is taken away according to the airflow in the machine.

[0139] It should be noted that Figure 5 and Fig.10 The heat dissipation layout shown is only an example, and the present application does not limit the specific layout position.

[0140] Optionally, in an embodiment of the present application, the filter module includes multiple filters, and the wavelength bands of the light beams obtained after filtering with different filters are different.

[0141] The control unit is also used to: determine the target filter in the filter module and the target position of the target filter; when it is determined that the target filter needs to be moved based on the target position and current position of the target filter, control the target filter to move to the target position.

[0142] The filter module is used to filter the first light beam or the second light beam through a target filter located at a target position.

[0143] It should be noted that if the filter is not needed, the output light module outputs the first light beam or the second light beam.

[0144] In the embodiment of the present application, when the target filter needs to be moved, the control module is used to send the target position of the target filter to the stepper motor in the cold light source of the endoscope; the stepper motor is used to move the target filter to the target position along the linear guide rail in the filter module.

[0145] Optionally, in the embodiment of the present application, the filter module further includes at least one optical coupler and a filter base, and a plurality of filters are fixed on the filter base.

[0146] Each of the at least one optical coupler is used to detect a position of the filter base.

[0147] The control module is also used to determine the current position of the target filter based on the position of the filter base sent by the optical coupler.

[0148] like Fig.11 As shown, a schematic diagram of the structure of a filter module in an embodiment of the present application is shown in FIG. Figure 1Among them, the module drive components are 13.1 stepper motor, 13.2 lead screw and linear guide module, 13.3 filter base, 13.6 filter base baffle, 13.7 optical coupler 1, 13.8 optical coupler 2, 13.9 optical coupler 3, and 13.10 optical coupler fixing seat.

[0149] Among them, multiple filters in the embodiment of the present application are fixed on a 13.3 filter base.

[0150] Optionally, the filter in the embodiment of the present application may be L-shaped, with one side fixed to the slider of the linear guide module and the other side fixed to the filter. The filter may be fixed to the filter base by bonding or crimping.

[0151] The filter module includes a plurality of filters, and the wavelength bands of the light beams obtained after filtering with different filters are different.

[0152] In the embodiment of the present application, 13.7 optical coupler 1, 13.8 optical coupler 2, and 13.9 optical coupler 3 are used to detect the position of the filter base. When the filter base baffle blocks the optical coupler, the optical coupler sends a position signal to the control unit.

[0153] based on Fig.11 , a schematic diagram of the structure of a filter module of a second viewing angle in an embodiment of the present application Figure 2 ,like Fig.12 As shown, taking the case where two filters are fixed on the filter base, 13.4 translation filter 1 and 13.5 translation filter 2 are fixed on the filter base, and a represents the light hole on the output optical module (the light output port in this solution).

[0154] like Fig.13 As shown, a flow chart of adjusting the filter base in an embodiment of the present application, the specific steps are as follows:

[0155] Step S1301: The control unit determines a target position of a filter base in a filter module.

[0156] It should be noted that, in the embodiment of the present application, for each illumination mode, a filter matching the corresponding illumination mode is pre-determined, that is, a filter to be used in each illumination mode is pre-determined.

[0157] Based on the position of the filter fixed on the filter base and the position of the light output port, the position of the filter base is determined when the filter is located in the direction of the light output port, and the position of the filter base is used as the corresponding target position in the illumination mode.

[0158] After determining the target illumination mode, the control unit determines the target position of the filter base corresponding to the target illumination mode based on the mapping relationship between the illumination mode and the target position of the filter base.

[0159] Step S1302: When the control unit determines that the filter base needs to be moved based on the target position and the current position of the filter base, the control unit controls the filter base to move to the target position.

[0160] Optionally, in the embodiment of the present application, the filter module further includes at least one optical coupler and a filter base, and the multiple filters are fixed on the filter base. Each optical coupler of the at least one optical coupler is used to detect the position of the filter base. The control module determines the current position of the target filter based on the position of the filter base sent by the optical coupler.

[0161] The embodiment of the present application compares the target position and the current position of the target filter. If they are different, it is determined that the filter base needs to be moved.

[0162] Optionally, in an embodiment of the present application, the control unit sends the target position of the filter base to the stepper motor in the cold light source of the endoscope, and the stepper motor translates the filter base to the target position along the linear guide rail.

[0163] In the embodiment of the present application, when the filter base is located at the target position, the filter module performs filtering processes of different procedures on the first light beam or the second light beam.

[0164] At this time, the light output port faces a direction with or without a filter.

[0165] If there is a filter, the filter is a target filter used in the target illumination mode, and the filter module filters the first light beam or the second light beam through the target filter.

[0166] If there is no filter, the first light beam or the second light beam is output from the light output port.

[0167] The specific positioning methods of the embodiments of the present application are as follows: Method 1, optocouplers 1, 2, and 3 are all blocked, indicating that the filter base 13.3 does not block the light hole a, which is equivalent to the no filter mode; Method 2, optocouplers 2 and 3 are blocked, and optocoupler 1 is not blocked, indicating that the translation filter 2 13.5 is at the light hole a, which is equivalent to the filter 2 mode; Method 3, optocoupler 3 is blocked, and optocouplers 1 and 2 are not blocked, indicating that the translation filter 13.4 is at the light hole a, which is equivalent to the filter 1 mode. Method 4, optocouplers 1, 2, and 3 are all not blocked, indicating that the module is overshooting, and the protection is activated. The program needs to adjust the motor to reverse to the normal position.

[0168] like Fig.14 As shown, the structure of a filter module of a third viewing angle in the embodiment of the present application is schematically shown in FIG. Figure 3Among them, the 13.3 filter base is fixed on the slider, and the rotational motion of the stepper motor is converted into linear motion through the lead screw, and the slide rail and slider are used as guides to ensure the motion accuracy.

[0169] Optionally, the slider and the 13.3 filter base are fixed by screws.

[0170] like Fig.15 As shown, an overall flow chart of a control unit control in an embodiment of the present application, the specific steps are as follows:

[0171] Step S1501, the control unit responds to the user's operation of selecting a target lighting mode based on the control trigger, determines at least one target light source component matching the target lighting mode from at least two types of light source components, and at least one target light source in each target light source component; and determines the target position of the filter base in the filter module.

[0172] In step S1502, the control unit determines whether the filter base needs to be moved based on the target position and the current position of the filter base; if so, step S1503 is executed; if not, step S1504 is executed.

[0173] Step S1503: the control unit controls the filter base to move to a target position, and controls at least one target light source to emit light.

[0174] Step S1504: the control unit controls at least one target light source to emit light.
