DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0040] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0041] In the embodiments of this application, "proximal end" and "distal end" refer to the relative distances of the endoscope and its accessories from the user in the usage environment. Among them, the end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "distal end".

[0042] Currently, an endoscope system is usually used in cooperation with a host. The host is not only equipped with a display screen and a power supply device for powering the endoscope and displaying the images it captures, but also integrates functions such as a processor, which can process and analyze the captured images, thereby helping doctors to more accurately judge the condition and provide diagnostic guidance, improving the accuracy of diagnosis. However, in most cases, the main function of the endoscope is only to display the images in the body cavity to assist the operation of other instruments. In this case, the host only needs to provide power supply and image display functions. However, due to the complex internal structure and high manufacturing cost of the host, the procurement and use costs of the overall system are also relatively expensive.

[0043] To address this problem, this application provides an adapter cable, an endoscope assembly, and an endoscope system. This system separates the power supply function and the image transmission function of the endoscope, reducing the dependence on the host. In simple inspection or operation scenarios, the endoscope can directly transmit the captured images to a display device without relying on a complex and expensive host system. By simplifying the system structure, this application effectively reduces the manufacturing and use costs of the endoscope system, especially in cases where no additional image processing is required, greatly reducing the complexity and cost burden of the equipment.

[0044] The following is combined with the attached Figures 1 to 5, a transfer cable, an endoscope assembly, and an endoscope system provided by an embodiment of the present application are described in detail through specific embodiments and their application scenarios.

[0045] The first aspect of this embodiment details a transfer cable.

[0046] An embodiment of the present application provides a transfer cable that is applied to an endoscope 10 and is specifically connected to the handle portion of the endoscope 10. This transfer cable not only provides electrical energy for the endoscope 10 but also transmits the images collected by the endoscope 10 to an external device. It should be noted that the transfer cable can be integrally connected to the endoscope 10 or connected in a detachable manner. In a disposable endoscope 10, if the transfer cable is integrally connected to the endoscope 10, it will be discarded together with the endoscope 10 after use; if it is connected in a detachable manner, the transfer cable can be separated from the endoscope 10 after use, the endoscope 10 is discarded, and the transfer cable can be reused. Through the detachable method, the user can separate the transfer cable from the endoscope 10 after operating the endoscope 10, thereby realizing the reuse of this cable. To a certain extent, this detachable design helps to save costs, especially in the scenario of a non-disposable endoscope 10, which is more convenient for equipment maintenance and independent handling of the transfer cable. In addition, the detachable connection also allows for more flexibility when the transfer cable is damaged or needs to be replaced, extending the service life of the equipment.

[0047] It should be noted that the terms "integral connection" and "detachable connection" do not refer to absolute connection forms but rather two main assembly methods. In actual applications, these two connection forms may be fine-tuned or optimized according to different operation requirements to adapt to the specific medical environment.

[0048] Referring to Figure 1 、 Figure 2 , the transfer cable includes a first main line 100. The distal end of the first main line 100 is adapted to be connected to the endoscope 10, and the proximal end of the first main line 100 is divided into a first wire bundle 200 and a second wire bundle 300. Among them, the first wire bundle 200 is adapted to be connected to a power supply device 30 to provide electrical energy for the endoscope 10, and the second wire bundle 300 is adapted to be connected to a display device 20 to display the images collected by the endoscope 10. Compared with the traditional endoscope 10 system, in this embodiment, by separating the power supply and image transmission functions, the dependence on a complex and expensive host is eliminated.

[0049] Due to the structural design of this transfer cable, the image signal of the endoscope 10 can be directly transmitted to the display device 20 without relying on the host for processing. In this way, in some scenarios that only require a display function, the overall complexity and cost of the endoscope 10 system are significantly reduced.

[0050] Among them, the proximal end of the first main line 100 is divided into a first wire bundle 200 and a second wire bundle 300, which means that the first main line 100 bifurcates near its proximal end to form two independent wire bundles. It can be understood that the proximal ends of the first main line 100, the first wire bundle 200, and the second wire bundle 300 refer to the end far from the endoscope 10, and the distal ends of the first main line 100, the first wire bundle 200, and the second wire bundle 300 refer to the end close to the endoscope 10.

[0051] It can be understood that the display device 20 can be a display, a monitor, or other devices suitable for displaying images, and the power supply device 30 can be a power adapter, a mobile power supply, or other devices for supplying electrical energy to the endoscope 10. The flexibility of this design enables users to select different display and power supply devices 30 according to specific usage scenarios, thereby further improving the applicability and economy of the system.

[0052] According to an optional embodiment, the distal end of the first main line 100 is used for detachably connecting to the endoscope 10. The purpose of this design is to retain and reuse the first main line 100 when the disposable endoscope 10 is discarded. In this way, resource waste can be reduced, the usage efficiency of components can be improved, and it helps to reduce the overall usage cost of the system.

[0053] According to an optional embodiment, the distal end of the first main line 100 is integrally connected to the endoscope 10. This design helps to improve the overall stability of the system in specific usage scenarios and avoid problems such as poor contact or signal interruption caused by frequent disassembly or connection. In addition, in the usage scenario of the disposable endoscope 10, the endoscope 10 is integrally connected to the first main line 100, which is convenient for the operator to uniformly process the device after use and simplifies the operation process.

[0054] According to an optional embodiment, the distal end of the first main line 100 is used for wireless signal connection to the endoscope 10. The purpose of this design is to provide greater flexibility and convenience, especially in some surgical or examination environments, to avoid the entanglement or limitation that may be brought by wired connection. Wireless signal connection can achieve signal transmission between the endoscope 10 and the first main line 100 while maintaining the mobility of the device and the freedom of operation. In this way, when the user performs relevant operations, the position of the endoscope 10 can be adjusted more flexibly, enhancing the usage experience. It can be understood that if the distal end of the first main line 100 is connected to the endoscope 10 by wireless signal, a power supply can be integrated inside the endoscope 10. This design enables the endoscope 10 to still operate normally without an external power supply cable, thereby supplying electrical energy to the endoscope 10.

[0055] According to an optional embodiment, refer to Figure 1 、 Figure 2, the length of the first wire harness 200 is greater than that of the second wire harness 300. It can be understood that the main purpose of the first wire harness 200 is to transmit electrical energy, while the second wire harness 300 is used to transmit the image information collected by the endoscope 10. Therefore, setting the length of the second wire harness 300 to be less than that of the first wire harness 200 can shorten the distance required for the endoscope 10 to transmit image information, thereby reducing signal loss and interference, and further improving the image display effect. This design optimizes the transmission efficiency of electrical energy and image information, ensuring a clearer and more stable image output during use.

[0056] It should be noted that by getting rid of the dependence on the host, the display device 20 can be closer to the operator. This layout not only shortens the length of the second wire harness 300, which helps to obtain a better image display effect, but also improves the operation flexibility. Since the display device 20 is closer to the operator, the operator can timely adjust the position and angle of the endoscope 10, thereby improving the surgical quality and efficiency. This design optimizes the overall operation experience of the endoscope 10 system, making the medical process smoother and more efficient.

[0057] According to an optional embodiment, referring to Figure 1 , Figure 2 , a first connector 110 is provided at the distal end of the first main line 100. The first connector 110 is used for detachable connection with the endoscope 10, and the first connector 110 is a connector with a TYPE-C interface. The purpose of this design is to provide a flexible connection method, enabling the endoscope 10 to be conveniently connected or disconnected from the first main line 100. At the same time, using a connector with a TYPE-C interface has good versatility and compatibility, and can support efficient data transmission and power supply, further improving the applicability and user experience of the endoscope 10 system.

[0058] According to an optional embodiment, a second connector 210 is connected to the proximal end of the first wire harness 200. The second connector 210 is used for detachable connection with the power supply device 30, and the second connector 210 is a connector with a DC interface. This design provides a convenient power supply connection method, enabling the power supply device 30 to be quickly connected or disconnected, facilitating the user to use the endoscope 10 in different environments. The connector with a DC interface has a stable power transmission ability, and can provide reliable electrical energy support for the endoscope 10, thereby ensuring the normal operation of the endoscope 10 during operation and improving the overall efficiency and use convenience of the system.

[0059] According to an optional embodiment, a third connector 310 is connected to the proximal end of the second wire harness 300. The third connector 310 is used for detachably connecting to the display device 20, and the third connector 310 is a connector of an HDMI interface. The HDMI interface can efficiently transmit high-definition image signals, ensuring that the images collected by the endoscope 10 can be transmitted to the display device 20 without loss, thereby providing clear and accurate image support for doctors. This design facilitates the quick connection of the endoscope 10 to different types of display devices 20 and allows for replacement or upgrade when needed, enhancing the flexibility and compatibility of the system.

[0060] According to an optional embodiment, a second connector 210 is connected to the proximal end of the first wire harness 200. The second connector 210 is used for detachably connecting to the power supply device 30 (refer to Figure 5 ), and a voltage stabilizing module is provided inside the second connector 210. Through the voltage stabilizing module, the electric energy transmitted from the power supply device 30 to the endoscope 10 can be stabilized to a certain extent, avoiding adverse effects on the normal operation of the endoscope 10 due to voltage fluctuations. The voltage stabilizing module generates heat during operation. By arranging the voltage stabilizing module in the second connector 210, the heat can be effectively dissipated, avoiding the risk of overheating caused by excessive heat concentration when the voltage stabilizing module is concentrated in the power supply device 30. In addition, arranging the voltage stabilizing module close to the endoscope 10 can perform timely stable regulation of the electric energy during transmission, thereby improving the stability and reliability of the power supply, helping to ensure the normal operation of the endoscope 10, and further optimizing the overall performance of the system.

[0061] According to an optional embodiment, a capacitor element is provided inside the second connector 210. By integrating the capacitor element in the second connector 210, it can play a role in smoothing current fluctuations during the transmission of electric energy, further improving the power supply stability and reducing the impact of voltage fluctuations on the normal operation of the endoscope 10. This structural design is beneficial to improving the reliability of the entire system.

[0062] It should be understood that in order to directly display the images collected by the endoscope 10 on the display device 20, an image processing device may be connected to at least one of the first main line 100, the first wire harness 200, and the endoscope 10. Through the image processing device, the information collected by the endoscope 10 can be processed, so that the signal collected by the endoscope 10 can be converted into a signal that can be recognized and displayed by the display device 20. Exemplarily, the image processing device includes a housing and a circuit board located inside the box. The circuit board is provided with an image processing unit. The image processing unit can receive the image signals captured by the endoscope 10, and then process the image signals and output signals that can be recognized and displayed by the display to directly display the images collected by the endoscope 10 on the display.

[0063] The second aspect of this embodiment will be described in detail for an endoscope assembly.

[0064] An embodiment of the present application provides an endoscope assembly. Referring to Figure 2 , Figure 4 , it includes an endoscope 10 and a patch cord in the above embodiment. Among them, the distal end of the first main line 100 is connected to the endoscope 10. Through this connection method, the dependence on the host can be eliminated, enabling the endoscope 10 to work independently of the host, thereby reducing system complexity, enhancing flexibility, and reducing the overall usage cost. In addition, this connection method also makes the operation of the endoscope 10 more convenient, which is beneficial to improving the efficiency and accuracy of medical operations.

[0065] According to an optional embodiment, the distal end of the first main line 100 is detachably connected to the endoscope 10. Through this design, when the use of the endoscope 10 is completed, the first main line 100 can be separated from the endoscope 10, facilitating the replacement or discard of the endoscope 10, while the first main line 100 can be reused, which helps to reduce the usage cost.

[0066] According to an optional embodiment, the distal end of the first main line 100 is integrally connected to the endoscope 10. This design can reduce the risk of loosening or damage at the connection part, ensure the stability of signal transmission and power supply between the endoscope 10 and the patch cord, and at the same time simplify the overall structure and improve the service life of the device.

[0067] According to an optional embodiment, the distal end of the first main line 100 is wirelessly connected to the endoscope 10. This design eliminates the limitation of physical connection and increases the flexibility of operation. In this case, the endoscope 10 can be built-in with a power supply so that it can still supply power to the endoscope 10 in the wireless connection state, further enhancing the convenience and operation freedom of the device.

[0068] According to an optional embodiment, referring to Figure 3 , Figure 4 , the endoscope 10 is provided with a fourth connector 11, and the distal end of the first main line 100 is detachably connected to the fourth connector 11. Through this design, a flexible connection between the endoscope 10 and the first main line 100 can be achieved. After the use of the endoscope 10 is completed, the first main line 100 can be separated from the fourth connector 11, thereby facilitating the replacement or maintenance of the endoscope 10 and enhancing the usage convenience of the device.

[0069] According to an optional embodiment, referring to Figure 4, the fourth connector 11 is integrally provided on the handle of the endoscope 10. This structural design helps to improve the stability of the connection and reduce the loosening or damage of the connection part caused by frequent operation. At the same time, the integrated design of the fourth connector 11 and the handle of the endoscope 10 simplifies the device structure and facilitates cleaning and operation.

[0070] In addition, the fourth connector 11 is connected to the endoscope 10 through the second main wire 12. This design improves the stability during connection. When the doctor operates the endoscope 10, the cable connected to the endoscope 10 will sag due to gravity, causing a large force on the connection between the cable and the endoscope 10. Especially during the movement or adjustment of the endoscope 10, it is easy to swing, thus affecting the stability of the operation.

[0071] If the fourth connector 11 is integrally provided on the handle of the endoscope 10, after the first main wire 100 is detachably connected to the fourth connector 11, during the actual operation process, the first main wire 100 and the fourth connector 11 may shake or loosen due to actions, thereby affecting the stability of the connection and resulting in unstable data transmission.

[0072] Refer to Figure 3 , by spacing the connection between the fourth connector 11 and the handle of the endoscope 10 through the second main wire 12, these problems can be effectively alleviated. Since the second main wire 12 and the handle of the endoscope 10 are integrally connected, the force between the endoscope 10 and the second main wire 12 will not cause shaking, enhancing the stability of the endoscope 10 and the reliability of the operation. Especially when the endoscope 10 is used for a long time, it can better ensure the firmness of the connection and the durability of the device.

[0073] The third aspect of this embodiment details an endoscope system.

[0074] An embodiment of the present application provides an endoscope system. Refer to Figure 5 , including a display device 20 and the endoscope assembly of the above technical solution. The display device 20 is connected to the second wire harness 300 to display the images collected by the endoscope 10. Through this design, the image information collected by the endoscope 10 is directly transmitted to the display device 20, enabling the doctor to view the situation inside the body cavity in real time, getting rid of the dependence on the host, thereby reducing the complexity and cost of the system and improving the flexibility and efficiency of the operation.

[0075] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
