Description

Technical Field

[0001] This utility model relates to the field of electronic endoscope technology, and in particular to a self-testing and self-calibrating device for an electronic endoscope system and an electronic endoscope system. Background Technology

[0002] Endoscopes have evolved from the initial optical and electronic endoscopes to the safer and more convenient disposable electronic endoscopes of today. An electronic endoscope system typically includes an image processor, a monitor, a disposable electronic endoscope, and other supporting surgical equipment. Because disposable electronic endoscopes are sterile packaged products, once the sterile packaging is opened, the endoscope cannot be reused and can become contaminated due to prolonged exposure to the environment. Therefore, in current technology, during the installation or surgical use of an electronic endoscope system, the image processor, monitor, and other supporting surgical equipment are generally installed and tested first. Only then is the sterile packaging of the disposable electronic endoscope opened, and the endoscope connected to the image processor for final installation, testing, and confirmation. However, due to the relative complexity of electronic endoscope systems, first-time users often fail to carefully read the user manual, leading to various unnecessary misoperations and abnormalities. In addition, the hardware conditions of different hospitals vary, such as different connection lines and the need to connect to various image and text management systems, which increases the difficulty of system installation and adjustment and often causes instability. This can result in the waste of disposable electronic endoscopes, or even delay surgery and cause personal injury.

[0003] To address installation and debugging issues, equipment engineers from manufacturers typically bring a calibration endoscope as an aid when assisting with medical installations. However, this only solves the initial installation problems and does not address the recalibration issues that hospitals may encounter during subsequent use or other installation changes. For example, if a disposable electronic endoscope malfunctions during use, and the hospital lacks readily available self-testing and calibration devices, it cannot determine whether the problem originates with the disposable endoscope or another piece of equipment.

[0004] However, how to design a self-testing and self-calibrating device for the installation and commissioning of electronic endoscope systems has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] To address the aforementioned technical problems, one embodiment of this utility model provides a self-testing and self-calibrating device for an electronic endoscope system. The self-testing and self-calibrating device is mechanically connected to an image processor via an anti-loss device. The self-testing and self-calibrating device includes:

[0006] shell;

[0007] A circuit board, wherein the circuit board is disposed within the housing;

[0008] A plug, located on the outside of the housing, is electrically connected to the circuit board and is used for plugging and unplugging into an endoscope socket on the image processor;

[0009] An image sensing module is electrically connected to the circuit board and is used to acquire image information.

[0010] Optionally, the self-testing and self-calibrating device further includes a lighting source, which is connected to the circuit board.

[0011] Optionally, the image sensing module includes an image sensor.

[0012] Optionally, the self-testing and self-calibrating device further includes an indicator light, which is electrically connected to the circuit board.

[0013] Optionally, the anti-loss device includes a lanyard, one end of which is connected to the housing and the other end of which is connected to the image processor.

[0014] Optionally, the image processor has a hook on its side wall, the housing has a mounting post, one end of the hanging rope has a closed-loop first connecting sleeve, which is fitted onto the mounting post; the other end of the hanging rope has a closed-loop second connecting sleeve, which is hung on the hook.

[0015] Optionally, the anti-loss device includes a threaded fastener, and the housing is fastened to the image processor by the threaded fastener.

[0016] Another embodiment of this utility model provides an electronic endoscope system, including an image processor, a display, and the self-testing and self-calibrating device described in the above embodiment. The image processor is provided with an endoscope socket, and the plug of the self-testing and self-calibrating device is pluggably connected to the endoscope socket. The image processor is used to process the image information received by the image sensing module and display it through the display.

[0017] Compared with the prior art, the technical solution of this utility model embodiment has the following beneficial effects:

[0018] Since disposable electronic endoscopes are sterile packaged products, once the sterile packaging is opened, the disposable electronic endoscopes cannot be reused and will become contaminated due to prolonged exposure to the natural environment. Therefore, before surgery, this invention uses a self-testing and self-calibrating device to replace the disposable endoscope and install it on the image processor for debugging the endoscope system. After debugging, the self-testing and self-calibrating device is removed, and then the disposable electronic endoscope is installed. This saves disposable electronic endoscopes and avoids unnecessary waste; it also greatly saves debugging time, thus ensuring the timeliness of the surgery.

[0019] Furthermore, the self-testing and self-calibrating device provided by this utility model is not only used for the installation and debugging of disposable electronic endoscopes before surgery, but also for subsequent use or re-calibration during other installation changes. For example, if any abnormality occurs during the use of a disposable electronic endoscope, it is not necessary to immediately replace it with a new disposable electronic endoscope. The self-testing and self-calibrating device can be used to connect the disposable electronic endoscope to the image processor for testing. If an image is displayed on the monitor, it indicates that the disposable electronic endoscope is abnormal and needs to be replaced in time. Therefore, when a disposable electronic endoscope malfunctions during use, the self-testing and self-calibrating device can promptly determine the location of the abnormality, which not only saves the number of disposable electronic endoscopes used and avoids unnecessary waste, but also greatly saves debugging time, thereby ensuring the timeliness of the surgery.

[0046] Please refer to Figures 1 to 4This invention provides a self-testing and self-calibrating device 4 for an electronic endoscope system. The electronic endoscope system generally includes an image processor 3, a display 1, and other supporting surgical equipment. The image processor 3 and the display 1 can be two independent separate structures, electrically connected via a connecting cable 2. Alternatively, the image processor and display can be integrated into a single machine; this invention does not impose specific limitations on this.

[0047] The image processor 3 is equipped with an endoscope socket 301, which is used to connect a disposable electronic endoscope. The self-testing and self-calibrating device 4 provided by this utility model is used to replace the disposable endoscope and is installed on the endoscope socket 301 before surgery to debug the endoscope system. After debugging, the self-testing and self-calibrating device 4 is unplugged and then the disposable electronic endoscope is installed.

[0048] Since disposable electronic endoscopes are sterile packaged products, once the sterile packaging is opened, the disposable electronic endoscopes cannot be reused and will become contaminated due to prolonged exposure to the natural environment. Therefore, before surgery, this invention uses a self-testing and self-calibrating device 4 instead of a disposable endoscope, installed on the image processor 3 to debug the endoscope system. After debugging, the self-testing and self-calibrating device 4 is removed, and then the disposable electronic endoscope is installed. This saves disposable electronic endoscopes and avoids unnecessary waste; it also greatly saves debugging time, thus ensuring the timeliness of the surgery.

[0049] Specifically, the self-testing and self-calibrating device 4 includes a housing 401, a circuit board 403, a plug 402, and an image sensing module 404. The circuit board 403 is disposed inside the housing 401. The plug 402 is disposed on the outside of the housing 401 and is electrically connected to the circuit board 403 for plugging and unplugging into the endoscope socket 301 on the image processor 3. This invention does not limit the specific structure of the endoscope socket 301 on the image processor 3; therefore, the plug 402 can be designed according to the actual structure of the endoscope socket 301, and this invention does not impose specific limitations in this regard.

[0050] As one embodiment, to facilitate the installation of structural components inside the housing 401, the housing 401 includes a front housing 40101 and a rear housing 40102, which are assembled together to form a receiving space for the circuit board 403. The plug 402 is disposed on the outside of the front housing 40101.

[0051] The image sensing module 404 is electrically connected to the circuit board 403 and is used to acquire image information. Since the image sensing module 404 represents a relatively mature technology in the optoelectronic field, this invention does not limit the specific structure of the image sensor module.

[0052] As one embodiment, the image sensing module 404 includes an image sensor mounted on the circuit board 403 for acquiring image information of the exterior of the housing 401. Furthermore, the image sensing module 404 also includes an imaging optical system, with the image sensor located at the imaging plane of the imaging optical system. The imaging optical system includes an objective lens facing outwards from the housing 401. Therefore, the image sensing module 404 acquires image information from the observation position, transmits it to the image processor 3 for processing to obtain a video image signal, and displays it on the display 1.

[0053] Furthermore, the self-testing and self-calibrating device 4 also includes an illumination device 405, which is used to illuminate the exterior of the housing 401.

[0054] When the self-test and self-calibration device 4 is connected to the image processor 3, the indicator light 406 can be used to check whether the self-test and self-calibration device 4 is working properly. Specifically, the self-test and self-calibration device 4 also includes an indicator light 406, which is electrically connected to the circuit board 403.

[0055] Working principle of self-testing and self-calibration device 4:

[0056] Insert the plug 402 of the self-testing and self-calibrating device 4 into the endoscope socket 301 of the image processor 3. When the indicator light 406 of the self-testing and self-calibrating device 4 lights up, and the image information acquired by the image sensing module 404 is processed by the image processor 3 and displayed on the monitor 1, it indicates that the electronic endoscope system is normal. If no image is displayed on the monitor 1, it indicates that the electronic endoscope system is abnormal and needs to be adjusted until an image is displayed on the monitor 1. Then unplug the self-testing and self-calibrating device 4 from the image processor 3, and then plug the disposable electronic endoscope into the image processor 3.

[0057] The self-testing and self-calibrating device 4 provided by this utility model is not only used for the installation and debugging of disposable electronic endoscopes before surgery, but also for subsequent use or re-calibration during other installation changes. For example, if any abnormality occurs during the use of the disposable electronic endoscope, it is not necessary to immediately replace it with a new disposable electronic endoscope. The self-testing and self-calibrating device 4 can be used to connect the disposable electronic endoscope to the image processor 3 for testing. If an image is displayed on the monitor 1, it indicates that the disposable electronic endoscope is abnormal and needs to be replaced in time. Therefore, when an abnormality occurs during the use of the disposable electronic endoscope, the self-testing and self-calibrating device 4 can promptly determine the location of the abnormality, which not only saves the number of disposable electronic endoscopes used and avoids unnecessary waste, but also greatly saves debugging time, thereby ensuring the timeliness of the surgery.

[0058] After the self-testing and self-calibrating device 4 completes its test and is removed from the image processor 3, to prevent its loss, this invention uses an anti-loss device to mechanically connect the self-testing and self-calibrating device 4 to the image processor 3. This invention does not limit the specific structure of the anti-loss device, as long as it allows the self-testing and self-calibrating device 4 to be mounted on the image processor 3 and prevents its loss.

[0059] Please refer to Figures 1 to 3 As one embodiment, the anti-loss device includes a lanyard 5, one end of which is connected to the outer casing 401, and the other end is connected to the image processor 3. In a specific embodiment, the outer casing is provided with a mounting post 407, one end of which is fixed to the front casing 40101, and the other end is fixed to the rear casing 40102 by insertion. One end of the lanyard 5 is provided with a closed-loop first connecting sleeve 501, which is sleeved on the mounting post 407. A hook 302 is provided on the side wall of the image processor, and the other end of the lanyard 5 is provided with a closed-loop second connecting sleeve 502, which is hung on the hook 302.

[0060] In a second embodiment, the anti-loss device includes a threaded fastener, and the housing 401 is fastened to the image processor 3 by the threaded fastener.

[0061] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
