[0002] In the multiplexing line connector that is docked at the proximal end of the endoscope handle, the circuit boards are all placed horizontally in the inner cavity of the shell. In order to adapt, it is usually necessary to lead out the cable from the axial tail end of the multiplexing line connector. After the multiplexing line is connected to the proximal end of the endoscope handle, the cable can be led out from the axial tail end of the handle. However, the internal structure of such a layout will cause the radial dimension of the shell to be very large, which will in turn cause the radial dimension of the entire multiplexing line structure to be very large, and the internal space of the shell will not be fully utilized, which increases the production cost.

[0003] Therefore, providing a multiplexing line with a compact internal structure and a medical device using the multiplexing line to reduce the production cost of the multiplexing line is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be described in detail below. Obviously, the embodiments described are only some of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other implementation methods obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.

[0028] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0029] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein 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".

[0030] The inventive concept of this application is described here:

[0031] In the multiplexing line connector that is docked at the proximal end of the endoscope handle, the circuit boards are placed horizontally in the inner cavity of the shell. In order to adapt, it is usually necessary to lead out the cable from the axial end of the multiplexing line connector. After the multiplexing line is connected to the proximal end of the endoscope handle, the cable can be led out from the axial end of the handle.

[0032] However, this layout, due to the horizontal placement of the circuit board, will result in a very large radial dimension of the housing, which in turn will result in a very large radial dimension of the entire multiplexing cable structure. At the same time, because the cables are led out from the axial end of the multiplexing cable connector, this will increase the axial dimension of the entire endoscope, making the endoscope very large in both the axial and radial directions, increasing production costs. In addition, the internal space of the multiplexing cable housing is not fully utilized.

[0033] In addition, the inventors found that since the cable is led out from the tail end of the multiplexing line connector axis, when using the endoscope, the user will need to rotate the endoscope for inspection according to the particularities of areas inside the human body such as the intestines. At this time, the end face of the endoscope may face the user's body, and the cable may abut against the user's body, causing the user's operating space to be compressed, thereby affecting the smoothness of the user's use.

[0034] Based on this, the inventors provide a multiplexing line and a medical device, which at least partially improve the above-mentioned problem by redesigning the layout of the internal structure of the multiplexing line.

[0035] The following is combined with Figures 1 to 7 , the multiplexing line 20 and medical device 1 provided in this application are described in detail through specific embodiments and their application scenarios.

[0036] See also Figure 1 An embodiment of the present application provides a medical device 1, which can be used to assist doctors in examining patients. It should be noted that the medical device 1 provided in the embodiment of the present application may include an endoscope, but is not limited to an endoscope, and may also be a catheter, a probe, etc.

[0037] The medical device 1 may include a body 10 and a multiplexing line 20. The body 10 may be held by a user and used to test a patient. The multiplexing line 20 may be connected to the body 10 and used for data transmission. For example, the body 10 may transmit the test results to a terminal device via the multiplexing line 20 so that the user can quickly and accurately obtain the test results. The embodiments of the present application do not limit the specific form and structure of the body 10, and may be specifically configured according to actual conditions.

[0038] See also Figure 2-Figure 4 The multiplexing line 20 may include a housing 210 , a PIN needle 220 , a circuit board 230 and a data line 240 , wherein the PIN needle 220 , the circuit board 230 and the data line 240 are all arranged inside the housing 210 .

[0039] Specifically, the housing 210 may include a first housing 213, a second housing 214, and a third housing 215. The first housing 213, the second housing 214, and the third housing 215 may be configured to be detachably connected and may be joined together to form a complete housing. An installation space 211 may be formed within the housing, and the installation space 211 may extend along the axial direction of the housing 210. That is, in this embodiment, the housing 210 may be configured to be tubular or similar in structure. The surface of the housing 210 may have an installation hole 212, which may be used to connect the data cable 240.

[0040] See also Figure 5 In a specific embodiment, the first shell 213 and the second shell 214 can be spliced together. One of the first shell 213 and the second shell 214 has a splicing post, and the other shell has a splicing hole at a position corresponding to the splicing post. The splicing post can be embedded in the splicing hole. More specifically, the splicing post can be interference-fitted with the splicing hole, which facilitates assembly and disassembly between the first shell 213 and the second shell 214, and further facilitates the inspection or replacement of components within the shells.

[0041] In one embodiment, the splicing column can be set in the second shell 214 and extend in an axial direction perpendicular to the installation space 211. The first shell 213 can have a first notch 213a, and the second shell 214 can have a second notch 214a. When the first shell 213 and the second shell 214 are spliced together, the first notch 213a can be combined with the second notch 214a to form a mounting hole 212.

[0042] See also Figure 6 In this embodiment, at least a portion of the data cable 240 is embedded in the mounting hole 212 and extends deep into the mounting space 211. This improves the stability of the connection between the data cable 240 and the housing 210. Specifically, the data cable 240 can be simultaneously inserted into the first notch 213a and the second notch 214a. During the assembly of the data cable 240 to the housing 210, the data cable 240 can first be inserted into one of the first notch 213a and the second notch 214a. Then, during the splicing process of the first housing 213 and the second housing 214, the data cable 240 can be inserted into the other of the first notch 213a and the second notch 214a to complete the assembly of the data cable 240 to the housing. In this embodiment, because the data cable 240 is simultaneously inserted into the first notch 213a and the second notch 214a, the stability of the connection between the data cable 240 and the housing 210 can be further improved.

[0043] Furthermore, in this embodiment, the axis direction of the mounting hole 212 may have an angle with the extension direction of the mounting space 211. That is, compared to the prior art solution in which the axis direction of the mounting hole 212 is the same as the extension direction of the mounting space 211, the embodiment of the present application sets the mounting hole 212 on the side of the housing 210, and then sets the connecting line on the side. Even if the end face of the housing 210 is facing the user's body during use, the multiplexing line 20 will not press against the user's body. The structure of the multiplexing line 20 provided in the embodiment of the present application is conducive to improving the smoothness of the user's use.

[0044] It should be noted that the embodiments of the present application do not limit the specific degree of the aforementioned angle. For example, in one embodiment, the aforementioned angle can be an obtuse angle, preferably between 120° and 150°. This allows the data cable 240 to extend obliquely outward from the housing 210, which helps increase the free space for the user's hand holding the medical device 1 and reduces the possibility of the data cable 240 blocking the user's hand. For example, in another embodiment, the aforementioned angle can also be a right angle, that is, the hole axis direction of the mounting hole 212 can be perpendicular to the extension direction of the mounting space 211. This can help reduce the wiring length between the circuit board 230 and the data cable 240 (the connecting cable is not shown in the figure).

[0045] Also, please review Figure 3 In one embodiment, the housing 210 may include a constricted portion 217 and a connecting portion 218. The cross-sectional dimensions of the constricted portion 217 are smaller than those of the connecting portion 218, and the mounting hole 212 may be provided in the constricted portion 217. Specifically, the third housing 215 is located in the connecting portion 218, and the end of the first housing 213 proximal to the third housing 215 and the end of the second housing 214 proximal to the third housing 215 are also located in the connecting portion 218. The end of the first housing 213 distal to the third housing 215 and the end of the second housing 214 distal to the third housing 215 are also located in the constricted portion 217. It will be appreciated that since the constricted portion 217 does not contain any functional components and is solely used to accommodate wiring, the cross-sectional dimensions of the accommodation portion may be smaller than those of the connecting portion 218. This further reduces the size of the entire housing 210, increases the utilization of the installation space 211, and thereby helps reduce the production cost of the entire multiplexing cable 20.

[0046] The third shell 215 can be a ring-shaped structure. One end of the third shell 215 is spliced with the first shell 213 and the second shell 214, and the other end has a connection port 216. The connection port 216 can be used for the PIN needle 220 set in the installation space 211 to connect to the terminal device.

[0047] See also Figure 7 The PIN needle 220 can be set in the installation space 211. In this embodiment, the PIN needle 220 can include an insulating seat 221, a lead connector 222 and a needle head, wherein the insulating seat 221 can be set in the installation space 211 and connected to the third shell 215.

[0048] The insulating seat 221 can serve as a base for installing the PIN needle 220. The embodiment of the present application does not limit the specific structure of the insulating seat 221. For example, in one embodiment, the insulating seat 221 can be arranged in the installation space 211 and used to close the installation space 211. This can prevent external impurities from entering the installation space 211, which is conducive to ensuring that the circuit board 230 remains stable during operation and is not affected by the outside world.

[0049] The lead connector 222 can be set on the insulating seat 221 and extend into the installation space 211. That is, in this embodiment, the lead connector 222 has an extension direction and can be electrically connected to the circuit board 230 (the connecting cable is not shown in the figure).

[0050] The needle can be set on the insulating seat 221 and extend toward the connection port 216. One end of the needle can be electrically connected to the lead connector 222, and the other end can be used to connect to the terminal device. The embodiment of the present application does not limit the extension length of the needle. For example, in one embodiment, the needle can extend out of the connection port 216, which makes it easier for the user to see the needle intuitively and connect the needle to the terminal device. For example, in another embodiment, the needle may not extend out of the connection port 216. In this embodiment, the third shell 215 can also be used to protect the needle to prevent the needle from being exposed and causing damage to the needle. The specific setting can be based on actual conditions and is not limited here.

[0051] In this embodiment, a plurality of lead joints 222 can be provided, and the plurality of lead joints 222 can be evenly arranged on the end surface of the insulating seat 221, and the circuit board 230 can be arranged between the plurality of lead joints 222. That is to say, in this embodiment, the lead joints 222 can be used to fix the circuit board 230, which not only facilitates the operation of installing the circuit board 230 on the insulating seat 221, but also improves the structural stability of the circuit board 230 when it is connected to the insulating seat 221. When the multiplexing line 20 accidentally falls, since the circuit board 230 is located between the lead joints 222, the lead joints 222 can also play a certain limiting effect on the circuit board 230, thereby reducing the risk of damage or displacement of the circuit board 230.

[0052] Specifically, circuit board 230 can be disposed within mounting space 211, with the width of circuit board 230 being greater than its thickness. The length of circuit board 230 is aligned with the direction in which PIN pins 220 extend, specifically, the length of circuit board 230 is aligned with the direction in which lead connectors 222 extend. This means that, unlike conventional methods of placing circuit board 230 horizontally within mounting space 211, in this embodiment, circuit board 230 is placed vertically within mounting space 211, thereby reducing the radial dimension of housing 210.

[0053] It should be noted that the embodiment of the present application does not limit the specific connection position of the circuit board 230 and the insulating seat 221, and can be specifically set according to the actual structure of the circuit board 230. For example, in one embodiment, the circuit board 230 can be configured to have electrical contacts only on one side. In this case, the circuit board 230 can be set in the edge area of the insulation, so that the lead connector 222 extending from the insulating seat 221 can be electrically connected to the electrical contacts on the circuit board 230. For another example, in another embodiment, the circuit board 230 can be configured to have electrical contacts on both sides. In this case, the circuit board 230 can be set on the central axis of the end face of the insulating seat 221. In this way, the lead connectors 222 located on both sides of the circuit board 230 can be conveniently electrically connected to the electrical contacts on the circuit board 230. At the same time, in this embodiment, since there are traces for electrical connection on both sides of the circuit board 230, the utilization efficiency of the installation space 211 can be improved.

[0054] In summary, the multiplexing line 20 provided in the embodiment of the present application, by setting the circuit board 230 in the installation space 211 of the shell 210, and setting the length direction of the circuit board 230 to be the same as the extension direction of the PIN needle 220, can fully utilize the installation space 211 in the axial direction of the shell 210, and at the same time can reduce the size of the radial direction of the shell 210, thereby making full use of the installation space 211, making the structure of the PIN needle 220, circuit board 230 and other components arranged in the installation space 211 more compact, and thus can also reduce the length of the wiring when the PIN needle 220, circuit board 230 and other components are electrically connected. The multiplexing line 20 provided in the embodiment of the present application is conducive to reducing the size of the entire shell 210, thereby reducing the production cost of the multiplexing line 20, and solving the problem of the large shell size of the multiplexing line in the prior art, the inability to fully utilize the internal space and the high production cost. Applying the above-mentioned multiplexing line 20 to the medical device 1 can also reduce the size of the entire medical device 1 and reduce the production cost of the medical device 1.

[0055] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0056] Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of the present application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in reverse order depending on the functions involved.
