Description

Technical Field

[0001] The present invention relates to the technical field of electronic endoscopes, and in particular to a self-checking and self-calibrating device of an electronic endoscope system and an electronic endoscope system. Background Art

[0002] Endoscopes have evolved from optical and electronic endoscopes to today's safer or more convenient disposable electronic endoscopes. Electronic endoscope systems generally include image processors, displays, disposable electronic endoscopes, and other supporting surgical equipment. Since disposable electronic endoscopes are sterile packaged products, they cannot be reused after the sterile packaging is opened, and they will also be contaminated due to long-term exposure to the natural environment. Therefore, in the prior art, during the installation or surgical use of electronic endoscope systems, image processors, displays, and other supporting surgical equipment are generally installed and debugged first, and finally the sterile packaging of the disposable electronic endoscope is opened, and the disposable electronic endoscope after the sterile packaging is opened is connected to the image processor for final installation, debugging, and confirmation. However, since the electronic endoscope system is relatively complex, first-time users often do not read the instruction manual carefully, resulting in various unnecessary misoperations and abnormalities. In addition, the hardware conditions of each hospital are also different. For example, different connection lines and various graphic management systems need to be connected, which increases the difficulty of system installation and adjustment, and stability is often abnormal, which may cause a waste of disposable electronic endoscopes at the least, and may delay surgery or even cause personal injury at the worst.

[0003] In order to solve the installation and debugging problems, the equipment engineers of existing manufacturers usually bring a debugging endoscope as an aid when helping with medical installation. However, this can only solve the problem of the equipment manufacturer's initial installation, and cannot solve the problem of re-debugging in the subsequent use of the hospital or other installation changes. For example, when a disposable electronic endoscope has an abnormality during use, the hospital does not have a convenient self-test and self-calibration device, so it is impossible to determine whether the disposable electronic endoscope has a problem or other equipment has a problem.

[0004] However, how to design a self-inspection and self-calibration device for installation and debugging of electronic endoscope systems has become a technical problem that needs to be solved urgently in this field. Summary of the invention

[0005] In order to solve the above technical problems, an embodiment of the present invention provides a self-inspection and self-calibration device of an electronic endoscope system, wherein the self-inspection and self-calibration device is mechanically connected to an image processor through an anti-lost device; the self-inspection and self-calibration device comprises:

[0006] shell;

[0007] A circuit board, wherein the circuit board is arranged in the housing;

[0008] A plug, arranged on the outside of the housing, electrically connected to the circuit board and used for plugging and unplugging connection with the endoscope socket on the image processor;

[0009] The image sensor module is electrically connected to the circuit board and is used to obtain image information.

[0010] Optionally, the self-test and self-calibration device further includes an illumination light source, and the illumination light source is connected to the circuit board.

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

[0012] Optionally, the self-checking 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, a hook is provided on the side wall of the image processor, a mounting column is provided on the outer shell, a closed-loop first connecting sleeve is provided at one end of the hanging rope, and the first connecting sleeve is mounted on the mounting column; a closed-loop second connecting sleeve is provided at the other end of the hanging rope, and the second connecting sleeve is hung on the hook.

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

[0016] Another embodiment of the present invention is an electronic endoscope system, comprising an image processor, a display and the self-inspection and self-calibration device described in the above embodiment, wherein the image processor is provided with an endoscope socket, the plug of the self-inspection and self-calibration device is pluggable and connected to the endoscope socket, and the image processor is used to process the image information obtained by the image sensor module and display it through the display.

[0017] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0018] Since the disposable electronic endoscope is a sterile packaged product, after the sterile package is opened, the disposable electronic endoscope cannot be reused and may also be contaminated due to long-term exposure to the natural environment. Therefore, before the operation, the present invention replaces the disposable endoscope with a self-checking and self-calibrating device installed on the image processor to debug the endoscope system. After debugging, the self-checking and self-calibrating device is unplugged, and then the disposable electronic endoscope is installed, thereby saving the disposable electronic endoscope and avoiding unnecessary waste; it also greatly saves debugging time, thereby ensuring the timeliness of the operation.

[0019] Furthermore, the self-checking and self-calibrating device provided by the present invention is not only used for the installation and debugging of disposable electronic endoscopes before surgery, but can also be used for subsequent use or re-debugging during other installation changes. For example, if any abnormality occurs during the use of a disposable electronic endoscope, there is no need to immediately replace it with a new disposable electronic endoscope. The disposable electronic endoscope can be connected to the image processor for detection by the self-checking and self-calibrating device. If an image is displayed on the display, it can be said that the disposable electronic endoscope has an abnormality and needs to be replaced in time. Therefore, when an abnormality occurs during the use of a disposable electronic endoscope, the location of the abnormality can be determined in time through the self-checking and self-calibrating device, which not only saves the number of disposable electronic endoscopes used and avoids unnecessary waste; it also greatly saves debugging time, thereby ensuring the timeliness of the operation.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. The terms "on" and "above" and any variations thereof are intended to describe positional relationships and do not represent a relationship of direct contact between the described objects.

[0046] Please refer to Figures 1 to 4The present invention provides a self-checking and self-calibrating device 4 for an electronic endoscope system, that is, the self-checking and self-calibrating device 4 is used in an electronic endoscope system. An electronic endoscope system generally includes an image processor 3, a display 1, and other supporting surgical equipment, etc. The image processor 3 and the display 1 can be two independent split structures, and the image processor 3 and the display 1 are electrically connected via a connecting line 2. The image processor and the display can also be an all-in-one machine, that is, the image processor and the display are integrated in one machine, and the present invention does not make specific restrictions on this.

[0047] An endoscope socket 301 is provided on the image processor 3, and the endoscope socket 301 is used to connect a disposable electronic endoscope. The self-inspection and self-calibration device 4 provided by the present invention is used to replace the disposable endoscope and be installed on the endoscope socket 301 before surgery to debug the endoscope system. After debugging, the self-inspection and self-calibration device 4 is unplugged, and then the disposable electronic endoscope is installed.

[0048] Since the disposable electronic endoscope is a sterile packaged product, after the sterile package is opened, the disposable electronic endoscope cannot be reused and may also be contaminated due to long-term exposure to the natural environment. Therefore, before the operation, the present invention replaces the disposable endoscope with a self-inspection and self-calibration device 4 installed on the image processor 3 to debug the endoscope system. After debugging, the self-inspection and self-calibration device 4 is unplugged, and then the disposable electronic endoscope is installed, thereby saving the disposable electronic endoscope and avoiding unnecessary waste; it also greatly saves debugging time, thereby ensuring the timeliness of the operation.

[0049] Specifically, the self-checking and self-calibrating device 4 includes a housing 401, a circuit board 403, a plug 402, and an image sensor module 404, wherein the circuit board 403 is disposed in the housing 401. The plug 402 is disposed outside the housing 401, and is electrically connected to the circuit board 403, and is used for plugging and unplugging with the endoscope socket 301 on the image processor 3. The present invention does not limit the specific structure of the endoscope socket 301 on the image processor 3, and therefore, the plug 402 can be set according to the actual structure of the endoscope socket 301, and the present invention does not specifically limit this.

[0050] As an embodiment, in order to facilitate the installation of the internal structural parts of the housing 401, the housing 401 includes a front housing 40101 and a rear housing 40102, which are assembled and connected to form an accommodating space for accommodating the circuit board 403. The plug 402 is arranged on the outside of the front housing 40101.

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

[0052] As an embodiment, the image sensing module 404 includes an image sensor, which is arranged on the circuit board 403 and is used to obtain image information outside the housing 401. Further, the image sensing module 404 also includes an imaging optical system, and the image sensor is located at the imaging surface of the imaging optical system. The imaging optical system includes an objective lens, which faces the outside of the housing 401. Therefore, the image sensing module 404 obtains image information at the observation position, transmits it to the image processor 3 for processing to obtain a video image signal, and displays it through the display 1.

[0053] Furthermore, the self-checking and self-calibrating device 4 also includes a lighting device 405 , and the lighting device 405 is used to illuminate the outside of the housing 401 .

[0054] When the self-checking and self-calibrating device 4 is connected to the image processor 3, in order to check whether the self-checking and self-calibrating device 4 works normally, it can be observed through the indicator light 406. Specifically, the self-checking and self-calibrating device 4 also includes an indicator light 406, and the indicator light 406 is electrically connected to the circuit board 403.

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

[0056] Insert the plug 402 of the self-checking and self-calibrating device 4 into the endoscope socket 301 of the image processor 3. When the indicator light 406 of the self-checking and self-calibrating device 4 is on and the image information acquired by the image sensor module 404 is processed by the image processor 3 and displayed on the display 1, it indicates that the electronic endoscope system is normal. If the display 1 does not display an image, it indicates that the electronic endoscope system is abnormal and needs to be debugged until the image is displayed on the display 1. Then unplug the self-checking and self-calibrating device 4 from the image processor 3 and plug the disposable electronic endoscope into the image processor 3.

[0057] The self-checking and self-calibrating device 4 provided by the present invention is not only used for the installation and debugging of the disposable electronic endoscope before the operation, but also can be used for subsequent use or re-debugging in other installation changes. For example, if any abnormality occurs in the disposable electronic endoscope during use, it is not necessary to immediately replace it with a new disposable electronic endoscope. The disposable electronic endoscope can be connected to the image processor 3 for detection by the self-checking and self-calibrating device 4. If an image is displayed on the display 1, it can be said that the disposable electronic endoscope has an abnormality and needs to be replaced in time. Therefore, when an abnormality occurs in the disposable electronic endoscope during use, the location of the abnormality can be determined in time through the self-checking and self-calibrating device 4, which not only saves the number of disposable electronic endoscopes used and avoids unnecessary waste; it also greatly saves debugging time, thereby ensuring the timeliness of the operation.

[0058] After the self-checking and self-calibrating device 4 is detected and unplugged from the image processor 3, in order to prevent the self-checking and self-calibrating device 4 from being lost, the present invention mechanically connects the self-checking and self-calibrating device 4 to the image processor 3 through an anti-lost device. The present invention does not limit the specific structure of the anti-lost device, as long as the self-checking and self-calibrating device 4 can be set on the image processor 3 to prevent it from being lost.

[0059] Please refer to Figures 1 to 3 As an embodiment, the anti-lost device includes a hanging rope 5, one end of which is connected to the housing 401, and the other end is connected to the image processor 3. In a specific embodiment, a mounting column 407 is provided on the housing, one end of which is fixed to the front housing 40101, and the other end is fixed to the rear housing 40102 by plugging. A closed-loop first connecting sleeve 501 is provided at one end of the hanging rope 5, and the first connecting sleeve 501 is sleeved on the mounting column 407. A hook 302 is provided on the side wall of the image processor, and a closed-loop second connecting sleeve 502 is provided at the other end of the hanging rope 5, and the second connecting sleeve 502 of the hanging rope 5 is hung on the hook 302.

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

[0061] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
