Description

Technical Field

[0001] This utility model belongs to the field of endoscope technology, specifically relating to an assembly structure for a pipe connector, an endoscope handle, and an endoscope. Background Technology

[0002] Endoscopes, as medical devices, are increasingly widely used in the medical field. An endoscope generally consists of a handle and an insertion section. One end of the insertion section is fixed to the handle, and the other end is equipped with a camera module. The insertion section is inserted into the human body, and the camera module captures images of internal structures and lesions.

[0003] The insertion section has an instrument channel through which surgical instruments can be used for surgery, and also for the introduction or extraction of fluids. The handle contains a tube that communicates with the instrument channel, and this tube is connected to devices such as tee connectors or suction valves. In existing technology, the tube and tee connectors / suction valves are usually fixed with adhesive. However, because the tube inside the handle is typically bent, it is constantly subjected to internal forces. The adhesive joints between the tube and the tee connectors / suction valves are prone to detachment due to these internal forces, affecting the use of the endoscope. Utility Model Content

[0004] The purpose of this application is to provide an assembly structure for a pipe connector, an endoscope handle, and an endoscope to solve the aforementioned technical problems existing in the prior art.

[0005] This application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide an assembly structure for a pipe connector used in an endoscope. The assembly structure includes a pipe connector for mounting to a handle housing. The pipe connector includes at least one connecting portion and at least one external interface. The connecting portion is used to adhesively fix to the handle housing, and the external interface is used to connect a tube. The external interface is disposed adjacent to at least one connecting portion so that the adhesive connecting the external interface and the tube can be bonded to the connecting portion.

[0007] Secondly, embodiments of this application provide an endoscope handle, including the assembly structure of the tube connector provided in the first aspect embodiment.

[0008] Thirdly, embodiments of this application provide an endoscope, including the endoscope handle provided in the second aspect embodiment.

[0009] The technical solution provided in this application can achieve the following beneficial effects:

[0010] In this application, the pipe fitting includes a connecting part and an external interface. The connecting part is used to glue and fix the pipe fitting to the handle housing, thus fixing the relative position of the pipe fitting and the handle housing. The external interface is used to connect the pipe fitting. By setting the external interface adjacent to at least one connecting part, the distance between the external interface and the connecting part is shortened. When using adhesive to bond the pipe fitting and the external interface, due to the fluidity of the adhesive, the adhesive can overflow to the connecting part, thereby bonding the connecting part, the pipe fitting, and the external interface together, improving the connection stability of the pipe fitting and the external interface, preventing the pipe fitting from falling off from the external interface, and ensuring the normal use of the endoscope.

[0024] The following description provides many different embodiments or examples for implementing various features of the present invention. The elements and arrangements described in the specific examples below are only for concise expression of the present invention and are merely examples, not intended to limit the present invention.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] This application provides an assembly structure for a pipe connector, which is used in an endoscope. (Refer to...) Figures 1 to 10 As shown, the assembly structure includes a pipe connector 100, which is a connector that communicates with the fitting 300, such as a tee connector, a suction valve, or other device. The pipe connector 100 is used to install into the handle housing 200 and communicates with the fitting 300 inside the handle housing 200.

[0027] The pipe connector 100 includes at least one connecting portion 110 and at least one external interface 120. The connecting portion 110 is used for adhesive fixation to the handle housing 200, securing the pipe connector 100 to the handle housing 200 and stabilizing the position of the handle housing 200. The external interface 120 is used for connecting a pipe fitting 300, which communicates with the pipe connector 100. The external interface 120 is disposed adjacent to at least one connecting portion 110 so that the adhesive connecting the external interface 120 and the pipe fitting 300 can adhere to the connecting portion 110. (See reference...) Figure 2 , Figure 4 , Figure 6 as well as Figure 8 As shown.

[0028] The external interface 120 and the connecting part 110 are arranged adjacent to each other, and the distance between the external interface 120 and the connecting part 110 is small. When the adhesive is dripped towards the connection position of the external interface 120 and the fitting 300, the adhesive has a certain fluidity and can overflow to the connecting part 110, thereby bonding the connecting part 110, the fitting 300 and the external interface 120 together, improving the connection stability of the fitting 300 and the external interface 120, preventing the fitting 300 from falling off the external interface 120, and ensuring the normal use of the endoscope.

[0029] The connecting part 110 is fixed to the handle shell 200, and its position is highly stable. The adhesive at the pipe 300 and the outer interface 120 is bonded to the connecting part 110, which can establish an indirect connection between the outer interface 120, the pipe 300 and the handle shell 200, thereby improving the connection stability between the pipe 300 and the outer interface 120.

[0030] Compared with the prior art, even if the fitting 300 is subjected to the same internal force, the adhesive between the two is also bonded to the connection part 110, which can bond the outer interface 120, the fitting 300 and the connection part 110 into an integral structure. The adhesive strength and stability between the fitting 300 and the outer interface 120 are higher, and the fitting 300 is not easy to detach from the outer interface 120.

[0031] In some embodiments, the fitting 300 may be sleeved on the outside of the external interface 120, as shown in the reference. Figure 9 and Figure 10 As shown, this design facilitates the bonding of the fitting 300 and the outer interface 120. Simultaneously, the overflow point of the adhesive at the contact point between the fitting 300 and the outer interface 120 is closer to the main body of the connector 100, allowing the adhesive to more easily overflow along the main body of the connector 100 to the connecting portion 110. The main body of the connector 100 refers to the portion of the connector 100 other than the outer interface 120 and the connecting portion 110. In other embodiments, the fitting 300 may be inserted into the interior of the outer interface 120.

[0032] The pipe connector 100 is fixedly connected to the handle housing 200. The pipe connector 100 can be entirely located inside the handle housing 200, or it can be partially located inside the handle housing 200 and partially located outside the handle housing 200. For example, the pipe connector 100 is a three-way valve, with part of the three-way valve located outside the handle housing 200.

[0033] In some preferred embodiments, the external interface 120 is disposed adjacent to and between the two connecting portions 110, as can be seen from... Figures 1 to 6As shown, both sides of the fitting 300 and the external interface 120 are bonded and fixed to the connecting part 110, which increases the connection area and the number of connection regions between the fitting 300, the external interface 120 and the connecting part 110, thereby improving the connection stability of the fitting 300 and the external interface 120.

[0034] A reinforcing rib 130 can also be fixedly connected between the external interface 120 and the connecting part 110. The reinforcing rib 130 is also part of the pipe fitting 100, as can be seen from [reference needed]. Figures 1 to 6 As shown. On one hand, the reinforcing rib 130 acts as a bridge between the outer interface 120 and the connecting part 110, making it easier for adhesive overflowing from the connection point between the fitting 300 and the outer interface 120 to flow to the connecting part 110, thus improving the adhesive bonding effect of the fitting 300. On the other hand, both the outer interface 120 and the connecting part 110 are protruding parts relative to the main structure of the pipe fitting 100. Fixing the two together can improve the positional stability of the outer interface 120 and the connecting part 110.

[0035] In some embodiments of this application, the assembly structure of the pipe connector 100 further includes a handle housing 200. The handle housing 200 includes a housing body 210 and a connecting arm 220. The pipe connector 100 is installed on the housing body 210. One end of the connecting arm 220 is connected to the inner wall of the housing body 210, and the other end is bonded and fixed to the connecting portion 110. The presence of the connecting arm 220 improves the connection flexibility between the handle housing 200 and the connecting portion 110. The connecting arm 220 can be set according to the actual position of the pipe connector 100 and the handle housing 200 after the pipe connector 100 is installed on the handle housing 200, thereby stably fixing the pipe connector 100 to the handle housing 200.

[0036] In some preferred embodiments, the connecting arm 220 is positioned closer to the external interface 120 than the connecting portion 110. Both the connecting portion 110 and the connecting arm 220 are positioned close to the external interface 120, but the connecting arm 220 is positioned closer to the external interface 120. (See reference...) Figures 5 to 8 As shown in the figure, the gap between the connecting part 110 and the external interface 120 has been enlarged to more clearly show the positional relationship between the connecting part 110, the connecting arm 220 and the external interface 120.

[0037] The adhesive connecting the outer interface 120 and the fitting 300 can bond not only to the connecting part 110 but also to the connecting arm 220, thereby bonding the outer interface 120, fitting 300, connecting part 110, and connecting arm 220 into a whole. These four components support each other, further improving the bonding and fixing effect between the fitting 300 and the outer interface 120. Furthermore, the connecting arm 220 is part of the handle shell 200. The bonding and fixing of the fitting 300 and the outer interface 120 to the handle shell 200 indirectly fixes the fitting 300 to the handle shell 200, enhancing the fixing effect of the fitting 300.

[0038] In some embodiments, the sidewall of the connecting arm 220 is fixedly connected to the connecting portion 110, and the end of the connecting arm 220 extends toward the outer interface 120. In other embodiments, the connecting portion 110 is provided with a through hole for the connecting arm 220 to pass through. The connecting arm 220 is inserted into the through hole of the connecting portion 110, and the adhesive between the outer interface 120 and the fitting 300 can bond to the connecting arm 220 and the inner wall of the through hole, improving the connection effect between the connecting arm 220 and the connecting portion 110, further improving the connection stability between the outer interface 120, the fitting 300, the connecting portion 110, and the connecting arm 220, and optimizing the adhesive strength.

[0039] Furthermore, since the connecting arm 220 and the connecting part 110 are both located adjacent to the external interface 120, and the connecting arm 220 also passes through the through hole on the connecting part 110, when the pipe fitting 100 is assembled to the handle housing 200, glue is dripped between the pipe fitting 300 and the external interface 120 to fix it. The glue can overflow to the connection position of the connecting arm 220 and the connecting part 110, thereby simplifying the assembly process of the pipe fitting 100.

[0040] In some preferred embodiments, the connecting portion 110 and the external interface 120 are arranged along the extending direction of the connecting arm 220, and the end of the connecting arm 220 is disposed relative to the connecting portion 110 and close to the external interface 120, the external interface 120 being located in the extending direction of the connecting arm 220. (See reference) Figure 9 and Figure 10 As shown, the connecting part 110 and the outer interface 120 are on the same straight line, with the end of the connecting wall closer to the outer interface 120. The connecting arm 220 is located directly below the outer interface 120. The connecting arm 220 can support the outer interface 120 in its extension direction. When the outer interface 120 is connected to the pipe fitting 300, it can simultaneously support the pipe fitting 300, playing a certain limiting role, thereby further improving the fixing effect between the pipe fitting 300 and the outer interface 120.

[0041] In some embodiments of this application, in addition to being fixedly connected to the housing body 210 via the connecting arm 220, the connecting portion 110 itself can also be directly connected to the housing body 210. (See reference...) Figure 9 and Figure 10 As shown, the connecting portion 110 presses against the inner wall of the shell body 210, and there is a connection area between the connecting portion 110 and the shell body 210. Furthermore, the portion of the connecting portion 110 that presses against the inner wall of the shell body 210 and the portion of the connecting portion 110 that is fixedly connected to the connecting arm 220 are both adjacent to the outer interface 120. With these three locations adjacent to each other, the adhesive between the fitting 300 and the outer interface 120 can be bonded to these three locations, thereby bonding them together and further improving the stability of the fixation between the fitting 300 and the outer interface 120.

[0042] A pipe fitting 100 may include multiple external interfaces 120, and the external interfaces 120 and the connecting portions 110 may be configured in any of the embodiments provided in this application. Different connecting portions 110 may be provided adjacent to different external interfaces 120, as described in this application. Figure 4 As shown, the pipe connector 100 has two external interfaces 120, one of which is located between two connecting portions 110. These connecting portions 110 are closer to the external interface 120 relative to their connected connecting arms 220. One external interface 120 corresponds to one connecting portion 110, which is further away from the external interface 120 relative to its connected connecting arm 220. In practical implementation, the specific positional structure between the connecting portion 110 and the external interface 120 can be determined based on the specific shape of the handle housing 200 and the arrangement of other internal components.

[0043] This application embodiment also provides an endoscope handle, including the assembly structure of the tube connector 100 provided in any of the above embodiments, and other necessary components such as the tube fitting 300 are also provided in the handle housing 200.

[0044] This application provides an endoscope, for reference... Figure 11 As shown, the endoscope includes the endoscope handle provided in the above embodiment. The endoscope also includes an insertion part 400, which is fixedly connected to the handle and communicates with the tube 300 inside the handle.

[0045] The endoscopes involved in the embodiments of this application may be bronchoscopes, pyeloscopes, esophagoscopes, gastroscopes, colonoscopes, otoscopes, rhinoscopes, oral endoscopes, laryngoscopes, colposcopes, laparoscopes, arthroscopes, etc. The embodiments of this application do not specifically limit the types of endoscopes.

[0046] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0047] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
