[0003] However, traditional endoscope systems mostly rely on wired connections. Due to the existence of connection cables, such connection methods are large in volume, complex in operation, and inconvenient for disinfection. They not only limit the doctor's operating freedom but may also cause problems such as operating room fires and medical infections. To a certain extent, they limit the operation flexibility and may cause inconvenience to patients. Content of the Utility Model

[0028] In order to make the objectives, technical solutions and advantages of the present utility model more clear, the following will further describe the present utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Please refer toFigures 1 - 3 This is a wireless and wired switching system for an endoscope disclosed in a utility model, which is used to realize data transmission between the endoscope and an external device, enabling wired or wireless data transmission between the endoscope main body 2 and the external device to improve the flexibility of use of the entire endoscope. Among them, the external device can be a device with a display module such as a mobile phone or a tablet.

[0030] The system mainly includes a camera module 1, an endoscope main body 2, a wired interface 3, a wireless transmitter 5, and a control unit.

[0031] The camera module 1 integrates at least one photosensitive chip, which is used to capture images and convert them into digital signals.

[0032] The endoscope main body 2 cooperates with the photosensitive chip to compress and convert the digital signal into an encoded signal suitable for transmission.

[0033] The wired interface 3 is used to physically connect the endoscope main body 2 and the external device through a signal line 4 for wired data transmission. In this embodiment, the wired interface 3 is preferably but not limited to a USB interface, and the signal line 4 is a USB-OTG connection line. One end of the USB-OTG connection line is a USB connector connected to the USB interface, and the other end is a TYPE-C interface connected to the external device, ensuring high-speed lossless data transmission between the endoscope main body 2 and the external device.

[0034] The wireless transmitter 5 is used to wirelessly transmit the image data captured by the endoscope main body 2 to the external device. In this embodiment, the wireless transmitter 5 can adopt the Wi-Fi standard of IEEE 802.11ac or 802.11ax, providing high-speed data transmission capabilities and better signal coverage, and can further improve the stability of signal transmission between the endoscope main body and the external device.

[0035] The control unit is used to control the switching of the endoscope main body 2 between the wired interface 3 and the wireless transmitter 5. Specifically, as Figure 2 shown, the control unit includes: a single-chip microcomputer, a mode switching module, a signal automatic switching module, and a decoding module. Among them, the wired interface 3 and the wireless transmitter 5 are respectively connected to the signal automatic switching module.

[0036] The endoscope main body 2 transmits the signal converted by the camera module 1 to the single-chip microcomputer for processing into an output image signal. The mode switching module is used to detect the connection status of the wired interface 3 and the signal line 4 and transmit the detection signal to the single-chip microcomputer. The single-chip microcomputer transmits the detection signal to the signal automatic switching module, and the signal automatic switching module identifies the detection signal and judges whether the wired interface 3 is connected to the signal line 4.

[0037] If the signal automatic switching module determines that the signal line 4 is connected to the wired interface 3, the signal automatic switching module will transmit the image signal to the wired interface 3. In this process, the camera module 1 will first transmit the encoded signal to the decoding module, and the decoding module will convert the picture signal of the endoscope body 2 into a video signal, so that the external device can directly obtain the display image through the connection of the wired interface 3 and the signal line 4.

[0038] If the signal automatic switching module determines that the signal line 4 is not connected to the wired interface 3, the signal automatic switching module will respond to the connection state between the wired interface 3 and the signal line 4 and automatically trigger the wireless transmission mode, and activate the wireless transmitter 5. Then, the signal automatic switching module will directly transmit the image signal to the wireless transmitter 5, so that the external device can directly wirelessly connect to the wireless transmitter 5 to obtain the display image.

[0039] The above control unit mainly realizes mode switching by running control software, such as Figure 3 As shown, the control software includes a camera signal acquisition program, a signal processing main program, and a signal switching program. Specifically, the camera signal acquisition program is integrated in the camera module 1, the signal processing main program is integrated in the single-chip microcomputer, and the signal switching program is integrated in the signal automatic switching module. Before each use, the control software will be initialized. After the software initialization, the camera signal acquisition program will convert the image captured by the endoscope body 2 into a video signal. The video signal is processed by the signal processing main program, and then the signal switching program will automatically switch the transmission mode between the wired interface 3 or the wireless transmitter 5 according to the detection signal of the mode switching module, so that the external device can display the image. When wired transmission is adopted, the signal switching program directly outputs the picture signal processed by the signal processing main program to the external device through the physical connection of the wired interface 3 and the signal line 4. When switching to wireless transmission, an output program is integrated in the wireless transmitter 5. The signal switching program directly transmits the picture signal processed by the signal processing main program to the output program, and then the output program wirelessly connects to the external device.

[0040] In summary, when the wired interface 3 is connected to the signal line 4 and the signal line 4 is connected to an external device, the endoscope main body 2 and the external device can be directly connected for image transmission, enabling the external device to immediately view the image. When wireless connection is required, unplug the signal line 4 to separate it from the wired interface 3, which can automatically wake up the wireless transmitter 5. At this time, starting the wireless connection module of the external device can perform WIFI image transmission. The switching operation is simple, the switching response speed is fast and stable, improving the flexibility and convenience of endoscope operation, replacing the prior art that only relies on wired transmission, and allowing free selection of the transmission working mode according to actual application requirements, greatly reducing medical accidents. More preferably, in order to accelerate the rapid switching between the two working modes during the use of the endoscope, the external device can first be connected to the host WIFI, which can ensure that when the wireless transmitter 5 is woken up for wireless transmission, it can be connected to the external device instantly. Among them, unplugging and plugging the signal line 4 for mode switching does not affect the use, so as to quickly handle emergencies encountered during use, such as when the signal line 4 is damaged and needs to be immediately switched to the wireless transmission working mode, or when the environmental signal is weak and needs to be immediately switched to the wired transmission working mode, avoiding interruption of the operation and further improving the flexibility of endoscope use.

[0041] In addition, to improve the practicality of the entire endoscope, the control software can also include a button subroutine and a power detection program. Among them, the button subroutine is connected to the signal switching program, and the button subroutine can be used for the photographing function or LED control. The user can trigger the endoscope to take a photo by pressing a physical button on the endoscope main body 2 or clicking a photo button on the operation interface of the connected external device to capture the currently observed image. Or the endoscope is usually equipped with an LED lamp for providing illumination to the observation area. The on / off state of the LED lamp or the brightness can be controlled through the button subroutine to adapt to different observation conditions.

[0042] Furthermore, to solve the problems of security and stability during data transmission, the single-chip microcomputer also integrates program functions such as an error detection and correction mechanism, an adaptive transmission rate adjustment program, and a multi-layer authentication protocol:

[0043] For example: The error detection and correction mechanism is used to ensure that the signal data received in the single-chip microcomputer is consistent with the signal data during transmission, guaranteeing the stability of signal transmission.

[0044] The adaptive transmission rate adjustment program is used to dynamically adjust the data transmission rate according to network conditions to achieve efficient data transmission.

[0045] The multi-layer authentication protocol is used to restrict the access of external devices, ensuring that only authorized devices can access the system, avoiding disrupting the operation site and preventing any unauthorized access or data leakage.

[0046] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
