[0071] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, but not all of the embodiments. Generally, the components of the embodiments of the present application described in the drawings herein can be arranged and designed in various different configurations.

[0072] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is claimed, but rather merely represents selected embodiments of the present application. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without creative effort are intended to fall within the scope of protection of this application. The following embodiments and features therein may be combined with each other unless there is a conflict.

[0073] In the description of this application, it is necessary to explain:

[0074] Relational terms such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation and do not necessarily require or imply any actual relationship or order between these entities or operations;

[0075] “Connection” should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0076] See Figure 2 The embodiment of the present application provides an endoscope host circuit system, which includes an isolation module and a system control and processing circuit. The isolation module includes a first group of ports and a second group of ports that are isolated from each other:

[0077] The first group of ports includes an isolated front light source port 1 and an isolated front camera port 2;

[0078] The second group of ports includes an isolated rear light source port 3 and an isolated rear camera port 4.

[0079] The isolated front light source port 1 is coupled with the isolated rear light source port 3, and the isolated front camera port 2 is coupled with the isolated rear camera port 4. The connection relationship between each port is as follows:

[0080] The isolated front light source port 1 and the isolated front camera port 2 are connected to the system control and processing circuit, the isolated rear light source port 3 is connected to the light source circuit, and the isolated rear camera port 4 is connected to the camera circuit.

[0081] like Figure 3 The light source circuit, isolation module, image processor circuit, and other system control and processing circuits are integrated into the endoscope mainframe chassis 105. The isolation module electrically isolates the light source and camera from the system control and processing circuits, meeting safety requirements and relevant standards. An optical fiber receptacle 106 can be provided on the front of the endoscope mainframe chassis 105, on which a touch screen 107 with touch control functionality can be installed.

[0082] The isolation module can use an isolation chip, such as the ADUM4166 isolation chip with a voltage resistance of up to 5.7kV, to prevent the current from the high-voltage circuit from flowing directly into the low-voltage circuit, protect personnel safety, meet the safety standards of endoscopes, and prevent damage to the system control and processing circuits, ensuring stable operation and safe use of the system with higher reliability.

[0083] The isolation module can include multiple isolation chips, and different isolation chips are used to isolate different signals. For example, the first isolation chip is used to isolate the light source electronic switch control signal, the second isolation chip is used to isolate the USB video signal of the camera, and the third isolation chip is used to isolate the serial port signal of the camera.

[0084] Regarding the control method of the light source, the system control and processing circuit can control the electronic switch through the isolated light source port 3, and the electronic switch controls the switching of the light source. Figure 4 The endoscope host circuit system may include a light source and an electronic switch, and the electronic switch is connected to the light source.

[0085] The isolated front light source port 1 may include an isolated front light source switch port 11, and the isolated rear light source port 3 may include an isolated rear light source switch port 31. The isolated front light source switch port 11 and the isolated rear light source switch port 31 are coupled. The isolated front light source switch port 11 is connected to the system control and processing circuit, and the isolated rear light source switch port 31 is connected to the control end of the electronic switch.

[0086] When the light source needs to be turned on or off, the system control and processing circuit can send a corresponding signal to the pre-isolated light source switch port 11. This signal is then transmitted through the isolation module to the post-isolated light source switch port 31, thereby controlling the electronic switch. The electronic switch can be a transistor with a switching function, such as a MOS transistor. The gate of the MOS transistor is connected to the post-isolated light source switch port 31, and the source and drain of the MOS transistor form a circuit with the power supply and light source.

[0087] like Figure 3 , the light source module should be turned on only after the optical fiber socket 106 of the endoscope is inserted into the optical fiber. In order to allow the system control and processing circuit to detect whether the optical fiber of the endoscope is inserted, Figure 5 It can be designed that the isolation front light source port 1 may include an isolation front light source signal port 12, and the isolation rear light source port 3 may include an isolation rear light source signal port 32, and the isolation front light source signal port 12 and the isolation rear light source signal port 32 are coupled. The isolation front light source signal port 12 is connected to the system control and processing circuit, and the isolation rear light source signal port 32 is connected to the fiber optic socket 106 of the endoscope.

[0088] The post-isolation light source signal port 32 transmits an endoscope fiber access signal when the endoscope fiber is connected to the fiber optic receptacle 106. The system control and processing circuit can receive the endoscope fiber access signal from the pre-isolation light source signal port 12 and then turn on the light source to allow light from the light source to enter the optical fiber.

[0089] like Figure 6 The isolated rear camera port 4 may include an isolated rear video signal port 41 and a camera power port 42. Camera power port 42 is used to provide power to the camera circuit. The isolated front camera port 2 may include an isolated front video signal port 21. The isolated rear video signal port 41 is coupled to the isolated front video signal port 21. The isolated front video signal port 21 is used to communicate with the camera circuit. The isolated front video signal port 21 is connected to the system control and processing circuit.

[0090] like Figure 7 The endoscope host circuit system may also include a non-isolated module; the non-isolated module is connected to the system control and processing circuit without electrical isolation.

[0091] like Figure 8 The non-isolated module may include a display, and the system control and processing circuit is connected to the display to convert the information carried by the video signal into an image for display.

[0092] like Figure 9The non-isolated module may also include a fan driver module and a light source temperature detection module. The system control and processing circuits are connected to the light source temperature detection module and the fan driver module, respectively. The fan driver module transmits a PWM signal to control the fan speed, thereby cooling the endoscope's light source. The light source temperature detection module can be implemented using the principle of a thermistor.

[0093] like Figure 9 The non-isolated module may also include a microphone, which is connected to the system control and processing circuit to realize the recording function. During diagnosis and treatment, the doctor can record the speech by recording the speech.

[0094] like Figure 9 The non-isolated module may also include a speaker, which is connected to the system control and processing circuit. The speaker can emit a prompt sound, such as a prompt sound when the optical fiber is successfully connected, and can also realize functions such as playing recordings.

[0095] like Figure 9 The non-isolated module may also include a touch screen connected to the system control and processing circuit. The user can control the light source through the touch screen.

[0096] Since the size of the display may be small for the sake of system portability, an interface board module can be set up, such as Figure 10 The interface board module connects to the system control and processing circuits and is used to connect to an external display. For example, the interface board module includes an SDI interface and a DVI interface, through which an external display can be connected. The interface board module can also be equipped with a USB interface and an RJ45 network port, which can be used to connect peripherals such as a mouse, keyboard, foot pedal, and printer.

[0097] Based on the above embodiments, an embodiment of the present application further provides an endoscope system, wherein the endoscope may include a display and may also include an interface board module; the system control and processing circuit is connected to an external display via the interface board module.

[0098] In general, the present application proposes an endoscope host circuit system and an endoscope system, in which the isolation module electrically isolates the light source and camera from the system control and processing circuits, which can meet safety requirements and relevant standards and enhance the reliability of the system.

[0099] The above-described device and system embodiments are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the present embodiment. Those skilled in the art may understand and implement the present invention without inventive effort.

[0100] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
