[0002] Currently, medical endoscope systems may include a light source unit and a camera unit. The light source unit is connected to the viewing mirror via a beam guide. The light source unit transmits the emitted illumination light to the viewing mirror through the beam guide. The viewing mirror is inserted into the human body, illuminating the human tissue and reflecting the light. The camera connected to the camera unit can collect the illumination light reflected by the human tissue, thereby forming image information and transmitting it to the camera unit. The camera unit then processes the image information and transmits it to the connected monitor for display, allowing doctors to examine the internal condition of the human body.

[0003] Different types of endoscopes may be required for different application scenarios, such as arthroscopy, sinus endoscopy, percutaneous endoscopic discectomy, and ventriculoscopy. However, current light source hosts do not yet have the function of identifying the type of endoscope currently connected. Utility Model Content

[0004] The main purpose of this utility model is to provide a light source host, a viewing mirror, a camera host, and an endoscope system that can identify the type of viewing mirror, in order to solve the technical problem that the light source host in the prior art does not have the function of identifying the type of viewing mirror currently connected.

[0022] In one embodiment, the light source host further includes: a first communication module;

[0023] The external camera host is equipped with a second communication module, which is electrically connected to the host module of the camera host. The first communication module is electrically connected to the identification module and the second communication module.

[0024] The first communication module is used to transmit the lens type signal corresponding to the lens type of the target recognition lens generated by the recognition module to the second communication module, so that the second communication module transmits the lens type signal to the host module, and then the host module determines the adjustment parameters corresponding to the lens type of the target recognition lens when it receives the lens type signal. The adjustment parameters are used to adjust the hardware parameters of the camera connected to the camera host through the camera host, and to adjust the software parameters of the captured image obtained by the camera.

[0025] In addition, to achieve the above objectives, this utility model also proposes a viewing mirror, which includes: a mirror body and an identity module;

[0033] In addition, to achieve the above objectives, this utility model also proposes an endoscope system, which includes a light source host capable of identifying the type of endoscope as described above, a viewing mirror as described above, and a camera host as described above.

[0034] This utility model proposes a light source host, a viewing mirror, a camera host, and an endoscope system capable of identifying different types of endoscopes. The light source host includes: an identification module and a host body equipped with a beam guide. The host body is detachably connected to an external target identification viewing mirror via the beam guide. The beam guide and the target identification viewing mirror are provided with corresponding contact points. The target identification viewing mirror is equipped with an identification module. The identification modules of different types of endoscopes are used to output different identification signals.

[0050] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0051] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0054] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, the user should consider such a combination of technical solutions to be non-existent and not within the scope of protection claimed by this utility model.

[0055] It should be noted that, referring to Figure 1 , Figure 1 A structural block diagram of a traditional endoscopic system, such as Figure 1 As shown, a current medical endoscope system may include a light source host 1 and a camera host 4. The light source host 1 may be equipped with a light source output interface, which can be connected to the beam guide 12 insertion port on the beam guide 12. Thus, the light source host 1 can be connected to the endoscope via the beam guide 12. The light source host 1 may contain a logic control chip (i.e.,... Figure 1The system includes an STM32103 chip and a light source module. The light source module outputs illumination light. The logic control chip of the light source host 1 controls the power of the illumination light output by the light source module. The light source module then transmits the emitted illumination light to the sight mirror (i.e., the beam guide 12) via the beam guide 12. Figure 1 (The light output is from the central illumination lens, which is inserted into the human body to illuminate the human tissue and reflect the light.)

[0056] The camera host 4 can be equipped with a camera interface (i.e. Figure 1 The camera uses a MIPI interface to connect to a camera. The camera can capture the illumination reflected from human tissue, forming an image and transmitting it to the logic control chip within the camera host 4. Figure 1 The camera host 4 can also be equipped with a video output interface (i.e., FPGA chip). Figure 1 The camera host 4 has an HDMI video output interface. The logic control chip inside the camera host 4 can process the image information and transmit it to the monitor for display through the video output interface, so that doctors can see the internal condition of the human body.

[0057] Different types of endoscopes may be required for different application scenarios, such as arthroscopy, sinus endoscopy, percutaneous endoscopic discectomy, and ventriculoscopy. However, current light source hosts do not yet have the function of identifying the type of endoscope currently connected.

[0058] To solve the above-mentioned technical problems, this embodiment provides a light source host 1 that can identify lens types. Since this embodiment can provide an identity module 21 on the target identification lens 2, the identity module 21 of the target identification lens 2 of different lens types can output different identity signals. An identification module 13 is provided in the light source host 1, and a corresponding contact point is provided on the beam guide 12 of the light source host 1 and the target identification lens 2. Then, when the target identification lens 2 is assembled with the beam guide 12, the identity module 21 of the target identification lens 2 can transmit the identity signal to the identification module 13 of the light source host 1 through the contact point. The identification module 13 can determine the lens type of the target identification lens 2 according to the identity signal, so that the light source host 1 can know the lens type of the currently connected lens.

[0059] For ease of understanding, the following is combined with Figures 2 to 10 The light source host 1 that can identify lens types provided in the embodiments of this application will be described in detail.

[0060] Reference Figure 2 as well as Figure 3 , Figure 2 This is a schematic diagram of the first embodiment of the light source host 1 capable of identifying lens types proposed in this utility model. Figure 3 This is a schematic diagram of the contact points in the first embodiment of the light source host 1 for identifying lens types according to this utility model. Figure 2 and Figure 3 As shown, in this embodiment, the light source host 1 includes: an identification module 13 (not shown in the figure) and a host body 11 with a beam guide 12;

[0061] The main body 11 is detachably connected to the external target recognition mirror 2 via the beam guide 12. The beam guide 12 and the target recognition mirror 2 are provided with corresponding contact points. The target recognition mirror 2 is provided with an identity module 21. The identity module 21 of the target recognition mirror 2 of different mirror types is used to output different identity signals. The contact points are used to connect the recognition module 13 and the identity module 21 when the beam guide 12 and the target recognition mirror 2 are assembled.

[0062] Understandably, in this embodiment, the beam guide 12 can be detachably connected to the target recognition sight 2, specifically, it can be detachably connected to the main body of the target recognition sight 2. The main body of the sight 2 can refer to all components of the target recognition sight 2 except for the subsequent identity module 21 and the sight contact point 32. The detachable connection methods include, but are not limited to, threaded connections and bayonet connections; this embodiment uses a threaded connection for illustration. That is, as... Figure 3 As shown, one end of the beam guide 12 can be connected to the light source host 1 to receive the light generated by the light source host 1. The other end of the beam guide 12 can be provided with an external thread, and an internal thread is provided at the corresponding position on the mirror body of the target recognition mirror 2. Through the cooperation of the internal and external threads, the end of the beam guide 12 away from the light source host 1 can be detachably connected to the mirror body of the target recognition mirror 2, so as to replace the mirror required in different scenarios.

[0063] It is also understood that the beam guide 12 can transmit light to the target recognition mirror 2, so that the user can insert the target recognition mirror 2 into the human body to provide light.

[0064] It should be emphasized that, in order for the target recognition sight 2 to demonstrate its own sight type, refer to Figure 4 , Figure 4 This is a structural block diagram of the target recognition viewing mirror 2 and the light source host 1 in the first embodiment of the light source host 1 that can identify different types of mirrors, as proposed in this utility model. Figure 4 As shown, in this embodiment, an identity module 21 may be provided on the target recognition mirror 2. That is, the target recognition mirror 2 includes not only the mirror body but also the identity module 21. The identity module 21 can be used to output an identity signal. The identity signals output by the identity module 21 of different types of target recognition mirrors 2 may be different. For example, the voltage value or current value of the output identity signal may be different. This embodiment does not limit this.

[0065] It should also be emphasized that, in order for the light source host 1 to be able to identify the type of the currently connected target recognition lens 2, it must continue as follows: Figure 3 as well as Figure 4 As shown, in this embodiment, when the beam guide 12 and the target recognition lens 2 are assembled, the contact point is provided at the contact point between the beam guide 12 and the target recognition lens 2. The contact point can be in the form of a metal sheet, or other conductive forms; this embodiment does not limit this. Furthermore, the position of the contact point can be any position where the beam guide 12 and the target recognition lens 2 contact during assembly, such as on internal or external threads, or other positions; this embodiment does not limit this.

[0066] Furthermore, this contact point allows the identification module 13 and the identity module 21 to be connected during the assembly of the beam guide 12 and the target identification lens 2. In actual use, when the user assembles the target identification lens 2 onto the beam guide 12 of the light source host 1, the identity module 21 on the target identification lens 2 can be connected to the identification module 13 on the light source host 1 through the contact point, and the identity module 21 can then transmit the corresponding identity signal to the identification module 13 through this contact point.

[0067] The identification module 13 is used to receive the identity signal output by the identity module 21 when it is connected to the identity module 21. The identity signal is used to determine the type of the target identification lens 2.

[0068] It should be understood that the aforementioned identification module 13 can be any module with identification function, such as a microcontroller unit (MCU). Since different lens types have different identification signals, this embodiment can store a preset lens type mapping table between different identification signals and their corresponding lens types within the identification module 13. For example, it could be a mapping table between identification signals with different voltage values ​​and their corresponding lens types. When the identification module 13 receives an identification signal, it can determine the lens type of the target identification lens 2 based on the voltage value of the identification signal.

[0069] It should also be understood that, such as Figure 1 As shown, due to the logic control chip (i.e., ...) inside the traditional light source host 1 Figure 1 The STM32F103 chip in the light source host 1 can have the above-mentioned recognition function. Therefore, in this embodiment, the preset mirror type mapping table between the identity signal with different voltage values ​​and the corresponding mirror type can be directly stored in the logic control chip in the light source host 1. Then, the logic control chip in the light source host 1 can determine the mirror type of the target recognition mirror 2 according to the voltage value of the identity signal, so that the light source host 1 has the ability to recognize mirror types.

[0070] Furthermore, in order to enable the identity signal of the identity module 21 to be transmitted to the identification module 13, the following steps are continued... Figure 4 As shown, in this embodiment, the contact point on the beam guide 12 is the beam guide contact point 31, and the contact point on the target recognition mirror 2 is the mirror contact point 32. The beam guide contact point 31 and the mirror contact point 32 make contact and conduction when the beam guide 12 and the target recognition mirror 2 are assembled.

[0071] The viewing mirror contact point 32 is electrically connected to the identity module 21, and the beam guide contact point 31 is electrically connected to the identification module 13. The viewing mirror contact point 32 is used to transmit the identity signal output by the identity module 21 to the identification module 13 through the beam guide contact point 31 when it makes contact with the beam guide contact point 31.

[0072] In this embodiment, the contact point on the beam guide 12 can be referred to as beam guide contact point 31, and the contact point on the target recognition sight mirror 2 can be referred to as sight mirror contact point 32. When the beam guide 12 and the target recognition sight mirror 2 are assembled, the beam guide contact point 31 can make contact with the sight mirror contact point 32 and conduct. The sight mirror contact point 32 can be electrically connected to the identity module 21, and the beam guide contact point 31 can be electrically connected to the recognition module 13. When the sight mirror contact point 32 and the beam guide contact point 31 make contact and conduct, the identity module 21 can transmit the identity signal through the sight mirror contact point 32 to the beam guide contact point 31 and then to the recognition module 13.

[0073] Furthermore, to enable the identity module 21 to generate an identity signal, as one implementation, a power supply and an identity signal generation circuit can be provided within the identity module 21. This identity signal generation circuit can convert the power supply voltage output by the power supply into an identity signal with a corresponding voltage value. For example, the power supply can be connected to a resistor with a corresponding resistance value. Moreover, for different types of target recognition lenses 2, resistors with different resistance values ​​can be set, and under the action of these resistors, the power supply voltage output by the power supply can be converted into an identity signal with a corresponding voltage value.

[0074] However, considering that setting a power supply in each target recognition mirror 2 would easily lead to resource waste and that the power supply voltage output by the power supply is difficult to keep consistent, in this embodiment, the recognition module 13 is also used to transmit the generated power supply voltage to the beam guide contact point 31 when the beam guide contact point 31 and the mirror contact point 32 are in contact and connected.

[0075] The beam guide contact point 31 is used to transmit the power supply voltage to the identity module 21 through the vision mirror contact point 32 to power it for operation.

[0076] The identity module 21 is used to output the identity signal when the device is powered on.

[0077] It should be noted that, in this embodiment, the identification module 13 can also be used to provide power supply voltage (i.e., the aforementioned power supply voltage). In actual use, when the beam guide contact point 31 and the viewing mirror contact point 32 are in contact and connected, the identification module 13 can output the power supply voltage, which is transmitted through the beam guide contact point 31 to the viewing mirror contact point 32. The viewing mirror contact point 32 then transmits the voltage to the identity module 21 of the target identification viewing mirror 2, thereby enabling the identity module 21 to power on and operate after receiving the power supply voltage, and then generate the corresponding identity signal for output. This eliminates the need to install a power supply in each target identification viewing mirror 2.

[0078] Furthermore, to facilitate the transmission of the aforementioned power supply voltage to the identity module 21, the following continues... Figure 4 As shown, in this embodiment, the beam guide contact point 31 includes a first beam guide contact point 311 and a second beam guide contact point 312, and the sight mirror contact point 32 includes a first sight mirror contact point 321 and a second sight mirror contact point 322.

[0079] In this embodiment, at least two contact points can be provided on the beam guide 12, denoted as the first beam guide contact point 311 and the second beam guide contact point 312, both of which can be metal sheets and can be set in a contactable position; at the same time, at least two contact points can be provided on the target recognition mirror 2, denoted as the first mirror contact point 321 and the second mirror contact point 322, both of which can also be metal sheets and can be set in a contactable position.

[0080] The first beam guide contact point 311 is electrically connected to the identification module 13. When the beam guide 12 is assembled with the target identification sight 2, the first beam guide contact point 311 makes contact with the first sight sight contact point 321 and conducts electricity. The first sight sight contact point 321 is electrically connected to the identity module 21. When the first beam guide contact point 311 makes contact with the first sight sight contact point 321 and conducts electricity, the first beam guide contact point 311 transmits the power supply voltage generated by the identification module 13 to the identity module 21 through the first sight sight contact point 321 to power it for operation.

[0081] The second viewing mirror contact point 322 is electrically connected to the identity module 21. When the beam guide 12 and the target recognition viewing mirror 2 are assembled, the second viewing mirror contact point 322 makes contact with the second beam guide contact point 312 and conducts through it. The second beam guide contact point 312 is electrically connected to the recognition module 13. When the second viewing mirror contact point 322 makes contact with the second beam guide contact point 312 and conducts through it, the identity signal output by the identity module 21 is transmitted to the recognition module 13.

[0082] Understandably, such as Figure 4As shown, in this embodiment, when setting the positions of the first beam guide contact point 311 and the first viewing mirror contact point 321, they can be set at positions where the beam guide 12 and the target recognition viewing mirror 2 can contact each other during assembly. That is, when the beam guide 12 and the target recognition viewing mirror 2 are assembled, the first beam guide contact point 311 and the first viewing mirror contact point 321 are in contact and connected. Similarly, when setting the positions of the second beam guide contact point 312 and the second viewing mirror contact point 322, they can be set at positions where the beam guide 12 and the target recognition viewing mirror 2 can contact each other during assembly. That is, when the beam guide 12 and the target recognition viewing mirror 2 are assembled, the second beam guide contact point 312 and the second viewing mirror contact point 322 are in contact and connected. The specific positions can be set according to the actual situation, and this embodiment does not impose any restrictions on them.

[0083] Furthermore, the first beam guide contact point 311 can be electrically connected to the identification module 13, and the first viewing mirror contact point 321 can be electrically connected to the identity module 21. When the first beam guide contact point 311 and the first viewing mirror contact point 321 are in contact and connected, the identification module 13 can transmit the generated power supply voltage through the first beam guide contact point 311 to the first viewing mirror contact point 321, and then the first viewing mirror contact point 321 can transmit it to the identity module 21 to power on, so that the identity module 21 generates an identity signal.

[0084] Similarly, the second beam guide contact point 312 can be electrically connected to the identification module 13, and the second viewing mirror contact point 322 can be electrically connected to the identity module 21. When the second beam guide contact point 312 and the second viewing mirror contact point 322 are in contact and connected, the identity module 21 can transmit the identity signal through the second viewing mirror contact point 322 to the second beam guide contact point 312, and then from the second beam guide contact point 312 to the identification module 13, so that the identification module 13 can determine the type of the target identification viewing mirror 2 according to the identity signal.

[0085] In this embodiment, an identity module 21 can be provided on the target recognition lens 2. The identity module 21 of the target recognition lens 2 of different lens types can output different identity signals. An identification module 13 is provided in the light source host 1, and a corresponding contact point is provided on the light guide beam 12 of the light source host 1 and the target recognition lens 2. Then, when the target recognition lens 2 and the light guide beam 12 are assembled, the identity module 21 of the target recognition lens 2 can transmit the identity signal to the identification module 13 of the light source host 1 through the contact point. The identification module 13 can determine the lens type of the target recognition lens 2 according to the identity signal, so that the light source host 1 can know the lens type of the currently connected lens.

[0086] Reference Figure 5 , Figure 5 The circuit diagram of the identity module 21 and the identification module 13 in the second embodiment of the light source host 1 that can identify the type of mirror proposed in this utility model is shown.

[0087] like Figure 5 As shown, in order to generate different identity signals for target recognition lenses 2 of different lens types, in this embodiment, the identity module 21 includes: a first resistor R1 and a fixed resistor Rg;

[0088] The first end of the first resistor R1 is electrically connected to the first sight mirror contact point 321, the second end of the first resistor R1 is electrically connected to the second sight mirror contact point 322 and the first end of the fixed resistor Rg, and the second end of the fixed resistor Rg is grounded.

[0089] It should be noted that the resistance value of the first resistor R1 can be different for different types of target recognition lenses 2. The specific resistance value can be set according to the actual situation, and this embodiment does not impose any restrictions on this. At the same time, the resistance value of the fixed resistor Rg can be the same for different types of target recognition lenses 2. Thus, the first resistor R1 and the fixed resistor Rg can form a voltage divider circuit. The corresponding lens type can be determined by measuring the voltage value at the second lens contact point 322. Specifically, if the voltage at the first lens contact point 321 is denoted as V1, then the voltage value V2 at the second lens contact point 322 can be V2 = (Rg) / (R1+Rg)*V1.

[0090] In actual use, when the first viewing mirror contact point 321 receives the power supply voltage, the first resistor R1 and the fixed resistor Rg can be energized, and then the second viewing mirror contact point 322 can collect the identity signal corresponding to the voltage value and transmit it to the second beam guide contact point 312.

[0091] Furthermore, considering that the aforementioned identity signal is an analog signal, in order to convert it into a digital signal that the microprocessor can recognize, the process continues as follows: Figure 5 As shown, in this embodiment, the identification module 13 includes: a conversion unit 131, a processing unit 132, and an identification unit 133;

[0092] The conversion unit 131 is electrically connected to the contact point and the processing unit 132, and is used to perform analog-to-digital conversion on the received identity signal and transmit the converted identity signal to the processing unit 132.

[0093] The processing unit 132 is electrically connected to the identification unit 133 and is used to determine the voltage value of the converted identity signal and transmit the generated voltage signal to the identification unit 133.

[0094] The identification unit 133 is used to determine the type of sight glass corresponding to the voltage signal.

[0095] Understandably, such as Figure 5As shown, in this embodiment, the conversion unit 131 can be a unit with analog-to-digital conversion function, and in this embodiment, the conversion unit 131 can be electrically connected to the first beam guide contact point 311 and the second beam guide contact point 312 respectively. The generated power supply voltage can then be transmitted to the first viewing mirror contact point 321 through the first beam guide contact point 311, so that the identity module 21 outputs an identity signal, receives the identity signal through the second beam guide contact point 312, performs analog-to-digital conversion on the identity signal, and transmits the converted identity signal to the processing unit 132.

[0096] After receiving the converted identity signal, the processing unit 132 can determine the voltage value corresponding to the converted identity signal and transmit it to the identification unit 133 in the form of the voltage signal. After receiving the voltage signal, the identification unit 133 can query the preset lens type mapping table to determine the lens type corresponding to the voltage value of the voltage signal, which is used as the lens type corresponding to the target identification lens 2.

[0097] Furthermore, such as Figure 5 As shown, in this embodiment, the conversion unit 131 includes: an analog-to-digital converter U1;

[0098] The signal input terminal of analog-to-digital converter U1 (i.e. Figure 5 The middle IN0~IN7) is connected to the second beam guide contact point 312, and the power supply terminal of the analog-to-digital converter U1 (i.e. Figure 5 The first pin of the analog-to-digital converter U1 is connected to the power supply (i.e., Figure 5 (+5V), the first beam guide contact point 311, and the first reference power supply terminal of the analog-to-digital converter U1 (i.e., + ...). Figure 5 The second pin of the analog-to-digital converter U1 is connected to the ground terminal of the analog-to-digital converter U1 (i.e., ...). Figure 5 Pin 11 of the analog-to-digital converter U1) and the second reference power supply terminal of the analog-to-digital converter U1 (i.e. Figure 5 The twelfth pin of the analog-to-digital converter U1 is connected, and the ground terminal of the analog-to-digital converter U1 is also grounded. The signal output terminal of the analog-to-digital converter U1 (i.e., Figure 5 Pins 17 to 24 of the analog-to-digital converter U1 are connected to the processing unit 132.

[0099] It should be understood that the analog-to-digital converter U1 mentioned above can be any device with analog-to-digital conversion function. For example, in this embodiment, the analog-to-digital converter U1 with model number ADC0809 is used. Of course, other models can also be used, and this embodiment does not limit this.

[0100] In actual use, the power supply (i.e. +5V) of the conversion unit 131 can output the power supply voltage and transmit it to the first sight mirror contact point 321 through the first beam guide contact point 311. The second beam guide contact point 312 can receive the identity signal and transmit it to the analog-to-digital converter U1 for analog-to-digital conversion. Then, the converted identity signal can be output through the signal output terminal of the analog-to-digital converter U1.

[0101] Furthermore, such as Figure 5 As shown, in this embodiment, the processing unit 132 includes: a processing chip U2;

[0102] The signal input terminal of the processing chip U2 (i.e. Figure 5 Pins 2 through 9 of the processing chip U2 are all connected to the signal output of the analog-to-digital converter U1. Specifically, pin 2 of the processing chip U2 is connected to pin 17 of the analog-to-digital converter U1, pin 3 of the processing chip U2 is connected to pin 18 of the analog-to-digital converter U1, pin 4 of the processing chip U2 is connected to pin 19 of the analog-to-digital converter U1, pin 5 of the processing chip U2 is connected to pin 20 of the analog-to-digital converter U1, pin 6 of the processing chip U2 is connected to pin 21 of the analog-to-digital converter U1, pin 7 of the processing chip U2 is connected to pin 22 of the analog-to-digital converter U1, pin 8 of the processing chip U2 is connected to pin 23 of the analog-to-digital converter U1, and pin 9 of the processing chip U2 is connected to pin 24 of the analog-to-digital converter U1. Simultaneously, the signal output of the processing chip U2 is connected to the identification unit 133.

[0103] It should be noted that the aforementioned processing chip U2 can be any chip capable of recognizing voltage values. For example, in this embodiment, a microprocessor of model 8051 is used. Of course, other models can also be used, and this embodiment does not impose any restrictions on this.

[0104] In actual use, the processing chip U2 can receive the converted identity signal through the signal receiving end, determine the voltage value of the converted identity signal, and transmit the generated voltage signal to the identification unit 133 through the signal output end of the processing chip U2.

[0105] It needs to be emphasized that, such as Figure 5 As shown, in this embodiment, the processing unit 132 further includes: a dual D flip-flop (i.e., Figure 5 The system includes a frequency divider (divided by 2), a first NOR gate, a second NOR gate, a first NOT gate, and a decoder;

[0106] The address latch terminal of processing chip U2 (i.e., the first pin of processing chip U2) is connected to one end of the dual D flip-flop, and the other end of the dual D flip-flop is connected to the clock terminal of analog-to-digital converter U1 (i.e., the thirteenth pin of analog-to-digital converter U1). The first address input terminal of analog-to-digital converter U1 (i.e., the clock input terminal of processing chip U2) is connected to the clock input terminal of analog-to-digital converter U1. Figure 5 The fourteenth pin of the analog-to-digital converter U1 is connected to the seventeenth pin of the analog-to-digital converter U1, and the second address input terminal of the analog-to-digital converter U1 (i.e., Figure 5 The fifteenth pin of the analog-to-digital converter U1 is connected to the eighteenth pin of the analog-to-digital converter U1, and the third address input terminal of the analog-to-digital converter U1 (i.e., Figure 5 The sixteenth pin of the analog-to-digital converter U1 is connected to the nineteenth pin of the analog-to-digital converter U1, and the interrupt terminal of the processing chip U2 (i.e., Figure 5 The tenth pin of the analog-to-digital converter U1 is connected to the input of the first NOT gate, and the output of the first NOT gate is connected to the conversion terminal of the analog-to-digital converter U1 (i.e., the terminal of the first NOT gate). Figure 5 The 25th pin of the analog-to-digital converter U1 is connected to the write pin of the processing chip U2 (i.e., Figure 5 The eleventh pin of the processing chip U2 is connected to the first input of the first NOR gate, and the output of the first NOR gate is connected to the start pin of the analog-to-digital converter U1 (i.e., Figure 5 Pin 26 of the analog-to-digital converter U1 and the address latch of the analog-to-digital converter U1 (i.e., Figure 5 The 27th pin of the analog-to-digital converter U1 is connected to the read pin of the processing chip U2 (i.e., Figure 5 The twelve pins of the processing chip U2 are connected to the second input of the second NOR gate, and the output of the second NOR gate is connected to the output enable pin of the analog-to-digital converter U1 (i.e., Figure 4 The 28th pin of the analog-to-digital converter U1 is connected to the first control terminal of the processing chip U2 (i.e., Figure 5 The thirteenth pin of the processing chip U2 is connected to the first input of the decoder. The output of the decoder is connected to the second input of the first NOR gate and the first input of the second NOR gate. The second control pin of the processing chip U2 (i.e., Figure 5 The fourteenth pin of the processing chip U2 is connected to the second input of the decoder, and the third control pin of the processing chip U2 (i.e., Figure 5 The fifteenth pin of the processing chip U2 is connected to the third input of the decoder.

[0107] It is understood that in this embodiment, the model of the dual D flip-flop can be 74LS74, the model of the first NOR gate and the second NOR gate can be 74LS02, the model of the first NOT gate can be 74LS04, and the model of the decoder can be 74LS138.

[0108] It should also be emphasized that, for the logic control chip in the traditional light source host 1 (i.e. Figure 1 For the STM32103 chip, relevant code can be set to enable the logic control chip in the light source host 1 to query the preset mirror type mapping table based on the voltage value. Therefore, in this embodiment, the identification unit 133 can be... Figure 1 The logic control chip in the light source host 1 can store the above-mentioned preset lens type mapping relationship table in advance. After the voltage signal output by the processing chip U2 is transmitted to the logic control chip in the light source host 1, the logic control chip in the light source host 1 can query the preset lens type mapping relationship table according to the voltage value corresponding to the voltage signal, thereby obtaining the lens type of the target recognition lens 2.

[0109] In this embodiment, refer to Figure 6 , Figure 6 This is a structural block diagram of the endoscope system in the second embodiment of the light source host 1 that can identify different types of endoscopes, as proposed in this utility model embodiment. Figure 6 As shown, in this embodiment, the aforementioned identification modules 13 can all be housed within the main body 11 of the light source host 1, and the conversion unit 131 can output the power supply voltage (i.e., Figure 6 The power supply voltage is transmitted to the sight mirror through the first beam guide contact point 311 on the beam guide 12, and the sight mirror outputs an identity signal (i.e., Figure 6 The identity signal is transmitted to the conversion unit 131 through the beam guide 12. The conversion unit 131 performs analog-to-digital conversion, and the processing unit 132 determines the corresponding voltage value (i.e., Figure 6 (Voltage value identification), and transmits the generated voltage signal to the identification unit 133 (i.e., Figure 6 Using the STM32F103 chip, the identification unit 133 can determine the type of the target identification lens 2.

[0110] Reference Figure 7 , Figure 7 This is a structural block diagram of the light source host 1 in the third embodiment of the lens type identification light source host 1 proposed in this utility model.

[0111] Considering that different types of sight glasses may be required in different usage scenarios (e.g., different departments), and due to the different optical characteristics of different types of sight glasses and the differences in cameras, it is necessary to adjust the software parameters (e.g., brightness, contrast, saturation) of the camera host 4 and the hardware parameters (e.g., shutter speed) of the camera host 4 to make them compatible with the sight glasses, thereby achieving better shooting and display effects. However, currently, when users change sight glasses, they need to manually adjust the parameters of the camera host 4 and the camera, which makes the operation cumbersome and the user experience poor. Therefore, if... Figure 7 As shown, in this embodiment, the light source host 1 further includes: a first communication module 42;

[0112] The external camera host 4 is equipped with a second communication module 43, which is electrically connected to the host module 41 of the camera host 4. The first communication module 42 is electrically connected to the identification module 13 and the second communication module 43.

[0113] The first communication module 42 is used to transmit the lens type signal corresponding to the lens type of the target recognition lens 2 generated by the recognition module 13 to the second communication module 43, so that the second communication module 43 transmits the lens type signal to the host module 41, and then the host module 41 determines the adjustment parameters corresponding to the lens type of the target recognition lens 2 when it receives the lens type signal. The adjustment parameters are used to adjust the hardware parameters of the camera connected to the camera host 4 through the camera host 4, and to adjust the software parameters of the captured image obtained by the camera.

[0114] It should be noted that, since there is no data exchange between the traditional light source host 1 and the camera host 4, when the user changes the viewing mirror, the parameters of the camera host 4 need to be manually adjusted, and the camera parameters need to be manually adjusted through the camera host 4. In this embodiment, the first communication module 42 can be installed in the lighting host, and the second communication module 43 can be installed in the camera host 4. The first communication module 42 and the second communication module 43 can be electrically connected via a cable. The first communication module 42 and the second communication module 43 can be any module that implements communication functions; this embodiment does not impose any restrictions on this.

[0115] In practical use, after the identification unit 133 of the identification module 13 in the light source host 1 determines the lens type of the target identification lens 2, it can generate the above-mentioned lens type signal and transmit it through the first communication module 42 to the second communication module 43 in the camera host 4. The second communication module 43 then transmits it to the host module 41 of the camera host 4. The host module 41 can be the logic control chip (i.e., Figure 6 (FPGA chip).

[0116] It should also be noted that in this embodiment, different lens types and their corresponding adjustment parameters can be pre-stored in the logic control chip within the camera host 4 in the form of a preset parameter mapping table. Then, when the logic control chip of the camera host 4 receives a lens type signal, it can query the preset parameter mapping table to obtain the corresponding adjustment parameters based on that lens type signal. These adjustment parameters can include hardware adjustment parameters and software adjustment parameters. Hardware adjustment parameters can be parameters used to adjust the hardware parameters of the camera (e.g., shutter speed), while software adjustment parameters can be parameters used to adjust the software parameters of the captured image (e.g., brightness, contrast, saturation). The specific hardware and software adjustment parameters corresponding to different lens types can be set according to actual conditions, and this embodiment does not impose any limitations on this.

[0117] After obtaining the adjustment parameters, the host module 41 can transmit the hardware adjustment parameters used to adjust the camera to the camera to adjust the camera's hardware parameters. The camera can then take pictures according to the hardware parameters and transmit them to the host module 41. The host module can then adjust the parameters of the captured image according to the software adjustment parameters in the adjustment parameters.

[0118] It is understood that in this embodiment, the host module 41 is also electrically connected to the display, so that after the host module 41 adjusts the parameters of the captured image, it can transmit it to the display for display.

[0119] like Figure 6 As shown, in this embodiment, a first communication module 42 (i.e., ...) can be set in the light source host 1. Figure 6 The RS485 communication interface is located in the light source host 1, and a second communication module 43 (i.e., ...) is set in the camera host 4. Figure 6 The RS485 communication interface in the camera host 4 can transmit the lens signal to the RS485 communication interface in the light source host 1, and then to the FPGA chip in the camera host 4. The FPGA chip then queries the preset parameter mapping table to determine the corresponding adjustment parameters, and then adjusts the parameters according to the adjustment parameters. The adjusted image is then transmitted to the display for display, thus eliminating the need for the user to manually adjust the parameters of the camera host 4 and the camera, improving the user experience.

[0120] Furthermore, referring to Figure 8 , Figure 8 The circuit diagram of the first communication module 42 in the third embodiment of the light source host 1 that can identify lens types proposed in this utility model is shown.

The second terminal of the fifth resistor R5 is connected to the inverting input of the receiver and the inverting output of the driver of the first communication chip U3, respectively.

[0123] It should be noted that the first communication chip U3 mentioned above can be a chip that supports 485 communication, such as the SP3485EN. Of course, other models can also be used, and this embodiment does not limit this.

[0124] It should also be noted that since this embodiment uses 485 communication, the first interface J1 mentioned above can be RS485.

[0125] Furthermore, referring to Figure 9 , Figure 9 The circuit diagram of the second communication module 43 in the third embodiment of the light source host 1 that can identify lens types proposed in this utility model is shown.

The second terminal of the tenth resistor R10 is connected to the inverting input of the receiver and the inverting output of the driver of the second communication chip U4, respectively.
