Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, and more specifically, to an image adapter cover, an endoscope, and an endoscope system. Background Technology

[0002] Endoscopes are generally available in two types: portable and non-portable. Portable endoscopes use a smaller display screen mounted on the handle, making them more flexible to use, but they also have drawbacks such as short battery life, weak image processing capabilities, and a small screen. Non-portable endoscopes, on the other hand, connect to a larger display screen via a cable plug. They do not have to worry about battery life and have advantages such as strong image processing capabilities, a large screen, and convenient observation, but they are less convenient to carry.

[0003] To combine the features of portable and non-portable endoscopes, the inventors discovered that an electrical interface could be added to the operating section of a portable endoscope for connecting a larger external display screen. However, this method has a drawback: without an electrical signal at the interface, the external display screen cannot properly display the images captured by the endoscope's image acquisition unit.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0044] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] As described in the background section, in order to combine the features of portable and non-portable endoscopes, the inventors discovered that an electrical interface could be added to the operating section of a portable endoscope. This electrical interface could be a wired cable for connecting a larger external display screen. However, this approach suffers from a problem where, without an electrical signal at the interface, the external display screen cannot properly display the images captured by the endoscope's image acquisition unit.

[0046] Based on this, please refer to Figures 1-8 This utility model provides an image adapter cover 100, an endoscope 1100, and an endoscope system 1000, which can effectively improve the aforementioned technical problems. Specifically, it enables the external display of the endoscope 1100 to normally display the images captured by the image acquisition unit 301. The image adapter cover 100, endoscope 1100, and endoscope system 1000 will be described in detail below.

[0047] Please refer to Figures 1-2 , Figure 1 This is a schematic diagram of the first connection method of the endoscope system 1000 provided in this embodiment. Figure 2 This is a schematic diagram illustrating a second connection method for the endoscope system 1000 provided in this embodiment. (In conjunction with...) Figure 1 and Figure 2 The endoscope system 1000 includes an endoscope 1100, a first display 1200 and a second display 1300. Both the first display 1200 and the second display 1300 are electrically connected to the endoscope 1100 to display images captured by the endoscope 1100 during the operation.

[0048] It should be noted that, as Figure 2As shown, the first display 1200 can be understood as a smaller display, which is directly mounted on the operating part 200 of the endoscope 1100 during use, making it convenient to carry and flexible to operate. Figure 1 As shown, the second display 1300 can be understood as a larger display. In some examples, the second display 1300 may include a control terminal 1301 and a display terminal 1302 connected together. In use, the control terminal 1301 is electrically connected to the operating part 200 of the endoscope 1100, that is, the corresponding electrical signals are transmitted to the display terminal 1302 through the control terminal 1301. The cooperation between the control terminal 1301 and the display terminal 1302 can make the image processing capability of the endoscope system 1000 strong and the screen large, which is convenient for observation. It is understood that the second display 1300 may also include only the display terminal 1302. This application does not limit the specific form of the second display 1300.

[0049] Please continue to combine Figure 1 and Figure 2 Specifically, the endoscope 1100 includes an image adapter cover 100, an operating section 200, and a tip section 300. The operating section 200 is provided with a first electrical interface 201 and a second electrical interface 202. The tip section 300 is connected to the operating section 200 and is provided with an image acquisition unit 301, which is electrically connected to the first electrical interface 201. When using the image adapter cover 100, the image adapter cover 100 is disposed on the operating section 200 and is used to transmit the electrical signal from the first electrical interface 201 to the second electrical interface 202.

[0050] To facilitate the installation of the operating unit 200 with the image adapter cover 100 or the display, the operating unit 200 is also provided with a top cover 203, where both the first electrical interface 201 and the second electrical interface 202 are located; the first display 1200 is used for electrical connection with the first electrical interface 201, and the second display 1300 is used for electrical connection with the second electrical interface 202. It should be noted that, as... Figure 1 As shown, when the second display 1300 needs to display an image, the control terminal 1301 of the second display 1300 is electrically connected to the second electrical interface 202, the image adapter cover 100 is connected to the top cover 203, and then the electrical signal from the first electrical interface 201 is transmitted to the second electrical interface 202, thereby realizing the transmission of the electrical signal from the image acquisition unit 301 to the second display 1300. Figure 2As shown, when the first display 1200 is needed to display an image, the image adapter cover 100 is first removed from the top cover 203, and then the first display 1200 is connected to the top cover 203, making the first electrical interface 201 electrically connected to the first display 1200, thereby directly transmitting electrical signals to the first display 1200. Through the above setup, the features of both portable and non-portable endoscopes 1100 can be combined, and the operation is convenient, adaptable to various application scenarios, and improving surgical efficiency.

[0051] Additionally, it should be noted that the tip 300 is also provided with an illumination unit 302. In some examples, the operating part 200 also includes a processing unit 303. The illumination unit 302 can provide illumination, facilitating observation during surgical procedures. Both the illumination unit 302 and the image processing unit 303 are electrically connected to the processing unit 303, which is electrically connected to the first electrical interface 201. Of course, it will be readily apparent to those skilled in the art that the endoscope 1100 may also include an insertion tube and a curved section, etc., which will not be elaborated upon in this embodiment.

[0052] Further, please refer to Figures 3-5 , Figure 3 This is a schematic diagram of the image adapter cover 100 provided in this embodiment. Figure 4 This is an exploded view of the image adapter cover 100 provided in this embodiment. Figure 5 This is a cross-sectional view of the image adapter cover 100 provided in this embodiment. (In conjunction with...) Figures 3-5 The image adapter cover 100 includes an adapter cover housing 10, an electrical plug 20, and an adapter 30. The electrical plug 20 is disposed inside the adapter cover housing 10 and has a first electrical terminal 21 and a second electrical terminal 22. The first electrical terminal 21 is used to electrically connect to the first electrical interface 201 of the endoscope 1100, and the second electrical terminal 22 is used to electrically connect to the second electrical interface 202 of the endoscope 1100. The adapter 30 is disposed inside the adapter cover housing 10 and is electrically connected to both the first electrical terminal 21 and the second electrical terminal 22.
