Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a movable connecting buckle, a sampling component, an endoscope system, and an assembly method thereof. Background Technology

[0002] In surgeries requiring sampling and testing, endoscopes are typically used in conjunction with sampling devices. Pathological fluid accumulations in areas such as the bronchi, abdominal cavity, and pelvic cavity can be collected using these devices for sample analysis. Currently, there are two methods for connecting the sampling device to the endoscope: one is to directly connect the sampling device to the endoscope's negative pressure nozzle and fix it to the side wall of the handle; the other is to have a fixing part on the handle housing for securing the sampling device, and then connect the negative pressure nozzle to the sampling device. However, both of these assembly methods present the problem of difficulty in quickly aligning and inserting the negative pressure nozzle on the endoscope with the collection port of the sampling device.

[0003] Therefore, providing an endoscope that allows for quick alignment and insertion of the negative pressure nozzle with the collection port of the sampling device is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This invention discloses a movable connecting buckle, a sampling component, an endoscope system, and its assembly method, in order to solve the technical problem in the related art that when connecting the sampling device and the endoscope, it is difficult to quickly align and insert the negative pressure nozzle on the endoscope with the collection port of the sampling device.

[0005] To solve the above problems, the present invention adopts the following technical solution: The first aspect of the present invention provides a movable connecting buckle.

[0006] The present invention provides a movable connecting buckle for connecting a sampling device and an endoscope. The movable connecting buckle includes a first connecting member and a second connecting member. One of the first connecting member and the second connecting member is connected to the sampling device, and the other is connected to the handle of the endoscope. One of the first connecting member and the second connecting member is provided with a guide portion, and the other is provided with a plug-in portion. The plug-in portion is plugged into the guide portion, and the plug-in direction is parallel to the axis of the negative pressure nozzle on the handle. When the plug-in portion is plugged into the guide portion, the negative pressure nozzle is aligned with the collection port on the sampling device.

[0007] A second aspect of the invention provides a sampling component.

[0008] The sampling assembly of the present invention includes a sampling device and a movable connecting buckle, wherein the sampling device includes a sampling bottle and a cap, the cap being closed at the opening of the sampling bottle; the movable connecting buckle is the movable connecting buckle described in any of the technical solutions of the present invention, and the first connecting member or the second connecting member of the movable connecting buckle is connected to the cap.

[0009] A third aspect of the present invention provides an endoscope system.

[0010] The endoscope system of the present invention includes a sampling device and an endoscope, wherein the sampling device and the endoscope are connected by a movable connecting buckle as described in any of the technical solutions of the present invention.

[0011] A fourth aspect of the present invention provides a method for assembling an endoscope system.

[0012] The assembly method of the endoscope system according to any one of the technical solutions of the present invention includes the following steps: Step 100-1: Connect one of the first connector and the second connector to the sampling device; Step 200-1: With the plug and guide parts in the plugged-in state, move the plug and / or the guide part to increase the distance between the first connector and the second connector; Step 300-1: Connect the other of the first connector and the second connector to the handle of the endoscope; Step 400-1: Move the plug and / or the guide to reduce the distance between the first connector and the second connector, while connecting the negative pressure nozzle to the collection port on the sampling device.

[0013] Alternatively, the assembly method of the endoscope system according to any technical solution of the present invention includes the following steps: Step 100-2: Connect one of the first connector and the second connector to the sampling device, and the other to the endoscope handle; Step 200-2: Connect the plug-in part to the guide part, move the plug-in part and / or the guide part, and reduce the distance between the first connector and the second connector, while connecting the negative pressure nozzle to the collection port on the sampling device.

[0014] The technical solution adopted in this invention can achieve the following beneficial effects: In a first aspect, the movable connecting buckle of the present invention includes a first connecting member and a second connecting member. One of the first connecting member and the second connecting member is provided with a guide portion, and the other is provided with a plug-in portion. The plug-in portion and the guide portion are plugged into each other. The plug-in direction of the plug-in portion is parallel to the axis of the negative pressure nozzle on the handle. Thus, when connecting the sampling device and the endoscope, the plug-in portion and the guide portion are plugged into each other, and the negative pressure nozzle is guided to move towards the collection port on the sampling device. After the plug-in portion and the guide portion are plugged into place, the negative pressure nozzle communicates with the collection port on the sampling device. This assembly structure, while realizing the connection between the sampling device and the endoscope, guides the insertion of the negative pressure nozzle through the cooperation of the plug-in portion and the guide portion, so that the negative pressure nozzle can be quickly aligned with the collection port of the sampling device and inserted into place, improving the accuracy and smoothness of the sampling device assembly.

[0015] Secondly, the movable connecting buckle of the present invention provides two assembly methods when connecting the sampling device and the endoscope, which can meet different assembly requirements. Both assembly methods of the present invention can guide the insertion of the negative pressure nozzle through the cooperation of the insertion part and the guide part, allowing the negative pressure nozzle to be quickly aligned with the collection port of the sampling device and inserted into place, thus improving the accuracy and smoothness of the sampling device assembly.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] In the various embodiments of this application, "near end" and "far end" refer to the distance of each component from the user in the usage environment. The end closer to the user is designated as the "near end", and the end farther from the user is designated as the "far end".

[0022] In related technologies, there are two ways to connect the sampling device to the endoscope: one is to fix the sampling device to the side wall of the handle by directly connecting it to the negative pressure nozzle of the endoscope; the other is to set a fixing part on the handle housing for fixing the sampling device, and then connect the negative pressure nozzle to the sampling device. In both of these methods, when connecting the sampling device to the endoscope, the negative pressure nozzle is connected to the sampling device in a blind insertion state, which makes it inconvenient to quickly align and insert the negative pressure nozzle with the collection port of the sampling device.

[0023] This application provides a movable connecting buckle, which includes two connectors. The two connectors are respectively connected to a sampling device and an endoscope. Each connector is provided with a plug-in part and a guide part. The plug-in part and the guide part are plugged into each other. The plug-in direction of the plug-in part is parallel to the axis of the negative pressure nozzle on the handle. Thus, when connecting the sampling device and the endoscope, the insertion action of the negative pressure nozzle can be guided by the cooperation of the plug-in part and the guide part, so that the negative pressure nozzle can be quickly aligned with the collection port of the sampling device and inserted into place.

[0024] The following is in conjunction with the appendix Figures 1 to 17 The present application provides a detailed description of the active connecting buckle, sampling component, endoscope system and assembly method provided by the present application through specific embodiments and application scenarios.

[0025] The first aspect of this embodiment describes the active connecting buckle 100 in detail.

[0026] The movable connecting buckle 100 in this embodiment is used to connect the sampling device 200 and the endoscope 300, so that the liquid aspirated by the endoscope 300 can enter the sampling device 200 for collection, such as... Figure 1 As shown. The sampling device 200 can be used to collect samples such as sputum. Figure 17As shown, the sampling device 200 includes a sampling bottle 210 and a cap 220. The sampling bottle 210 has an opening, and the cap 220 is fitted over the opening of the sampling bottle 210. The cap 220, also called a valve body, has a collection port 221, an exhaust port, and other structures. When using the sampling device 200, rotating the cap 220 allows the sampling bottle 210 to be connected to or disconnected from the suction channel of the endoscope 300. The structure of the cap 220 can be the same as in the prior art and will not be described in detail here. Figure 1 As shown, the endoscope 300 includes a handle 310 and an insertion portion 320, with the insertion portion 320 located at the distal end of the handle 310. The structure of the endoscope 300 can be the same as that of the prior art, and will not be described in detail here.

[0027] The movable connecting buckle 100 in this embodiment includes a first connecting member 110 and a second connecting member 120. One of the first connecting member 110 and the second connecting member 120 is connected to the sampling device 200, and the other is connected to the handle 310 of the endoscope 300. Figure 1 As shown. One of the first connector 110 and the second connector 120 is provided with a guide portion 111, and the other is provided with a plug portion 121, which is plugged into the guide portion 111. In subsequent embodiments, for clarity, the example given is that the first connector 110 is connected to the sampling device 200, and the second connector 120 is connected to the handle 310 of the endoscope 300, with the first connector 110 having the guide portion 111 and the second connector 120 having the plug portion 121. Figures 1-3 As shown.

[0028] like Figures 1-4 , Figures 8-10 As shown, the first connector 110 has a first fixing part 113, which is sleeved on the cover 220. The first fixing part 113 has a guide part 111, and the guide part 111 and the first fixing part 113 are integrally formed. The first fixing part 113 also has a negative pressure port 114, which is connected to an external negative pressure device. When the sampling bottle 210 is connected to the suction channel of the endoscope 300, the negative pressure device is activated, and the fluid inside the body can be aspirated into the sampling bottle 210 for collection.

[0029] like Figures 1-4 , Figure 12 and Figure 13 As shown, the second connector 120 has a second fixing part 122, which is snapped into and fixed to the handle 310. The second fixing part 122 is a snap-fit ​​structure adapted to the shape of the proximal end of the handle 310, and the handle 310 can be snapped into the cavity of the second fixing part 122. The second fixing part 122 is provided with a plug-in part 121, and the plug-in part 121 and the second fixing part 122 are an integral structure.

[0030] Preferably, the insertion direction of the insertion part 121 is parallel to the axis of the negative pressure nozzle 311 on the handle 310. In this embodiment, the insertion direction refers to the direction in which the insertion part 121 is inserted into the guide part 111, that is... Figure 3 The direction indicated by the middle arrow. The axis of the negative pressure nozzle 311 mentioned in this embodiment refers to the axis of the portion of the negative pressure nozzle 311 used for connecting with the sampling device 200, or the axis of the portion of the negative pressure nozzle 311 inserted into the movable connecting buckle 100. When the insertion part 121 and the guide part 111 are inserted, the negative pressure nozzle 311 is aligned with the collection port 221 on the sampling device 200.

[0031] See also Figure 3 and Figure 4 Along the insertion direction of the insertion portion 121 and the guide portion 111, the guide portion 111 and the insertion portion 121 have a certain length. For example, the length of the guide portion 111 and the insertion portion 121 is greater than or equal to 5 cm. This allows the negative pressure nozzle 311 to be guided to move towards the collection port 221 on the sampling device 200 when the insertion portion 121 moves along the insertion direction.

[0032] In this embodiment, the movable connecting buckle 100, when connecting the sampling device 200 and the endoscope 300, simultaneously engages the insertion part 121 with the guide part 111, guiding the negative pressure nozzle 311 towards the collection port 221 on the sampling device 200. Once the insertion part 121 and the guide part 111 are fully engaged, the negative pressure nozzle 311 communicates with the collection port 221 on the sampling device 200. This assembly structure, while connecting the sampling device 200 and the endoscope 300, guides the insertion of the negative pressure nozzle 311 through the engagement of the insertion part 121 and the guide part 111, allowing the negative pressure nozzle 311 to be quickly aligned and inserted into place with the collection port 221 of the sampling device 200, thus improving the accuracy and smoothness of the assembly of the sampling device 200.

[0033] like Figures 8-10 As shown, the guide portion 111 has a guide groove structure, and a protruding rib 1113 is provided inside the guide groove. The insertion portion 121 has a claw-type structure. Figure 12 and Figure 13 As shown, the insertion part 121 includes a first claw body 1213 and a second claw body 1214, which are separated from each other at least at their ends. After the insertion part 121 is inserted into the guide part 111, the first claw body 1213 and the second claw body 1214 are respectively located on the upper and lower sides of the protruding rib 1113, causing the insertion part 121 to move along the protruding rib 1113, thereby realizing the insertion engagement between the insertion part 121 and the guide part 111. Figure 5As shown. In addition, when the insertion part 121 and the guide part 111 are inserted and engaged, the first claw body 1213 and the second claw body 1214 apply a clamping force to the guide part 111, thereby preventing the insertion part 121 from detaching from the guide part 111.

[0034] Not limited to this, the plug-in portion 121 in this embodiment may not be a claw-type structure. For example, the plug-in portion 121 is a plug-in block structure, and the guide portion 111 is a guide groove structure. When the plug-in block is inserted into the guide groove, the plug-in block can also move along the guide groove, thereby still achieving the plug-in engagement between the plug-in portion 121 and the guide portion 111.

[0035] In some embodiments, the guide portion 111 is provided with a first limiting surface 1111, and the insertion portion 121 is provided with a second limiting surface 1211, such as... Figure 9 and Figure 12 As shown. After the insertion part 121 and the guide part 111 are inserted and engaged, when the insertion part 121 moves in the opposite direction to the insertion direction, the first limiting surface 1111 can abut against the second limiting surface 1211. Figure 4 A schematic diagram showing the contact between the first limiting surface 1111 and the second limiting surface 1211 is shown. The direction opposite to the insertion direction mentioned in this embodiment refers to the direction in which the insertion part 121 withdraws from the guide part 111, that is... Figure 3 The direction from left to right in the middle.

[0036] In this embodiment, the movable connecting buckle 100, after being assembled into the sampling device 200, prevents the insertion part 121 from detaching from the guide part 111 by the contact between the first limiting surface 1111 and the second limiting surface 1211. Thus, when adjusting the distance between the second connecting member 120 and the sampling device 200, it also avoids the problem of the second connecting member 120 detaching from the sampling device 200, which would cause assembly inconvenience.

[0037] In some embodiments, the insertion portion 121 is disposed on the first connector 110 or the second connector 120 connected to the handle 310, and along the insertion direction of the insertion portion 121, the first distance between the second limiting surface 1211 and the handle 310 is greater than or equal to the second distance between the end face of the negative pressure nozzle 311 and the handle 310. For example... Figure 14 As shown, the insertion part 121 is provided on the second connector 120. Along Figure 14 In the vertical direction shown, the second limiting surface 1211 is flush with the end face of the negative pressure nozzle 311. Or along... Figure 14 In the lateral direction shown, the second limiting surface 1211 is further away from the handle 310 than the end face of the negative pressure nozzle 311.

[0038] In this embodiment, the first distance between the movable connecting buckle 100, the second limiting surface 1211, and the handle 310 is greater than or equal to the second distance between the end face of the negative pressure nozzle 311 and the handle 310. Thus, when the insertion part 121 moves in the direction opposite to the insertion direction, the first connecting member 110 and the second connecting member 120 can provide sufficient clearance space for the endoscope 300, so that the endoscope 300 can be connected to the second fixing part 122.

[0039] In some embodiments, in the first connector 110 and the second connector 120, the one providing the guide portion 111 is further provided with a third limiting surface 1112, and the one providing the insertion portion 121 is further provided with a fourth limiting surface 1212, such as... Figure 8 and Figure 13 As shown. When the insertion part 121 and the guide part 111 are inserted and engaged, the third limiting surface 1112 and the fourth limiting surface 1212 abut against each other. Figures 1-3 , Figure 5 A schematic diagram showing the contact between the third limiting surface 1112 and the fourth limiting surface 1212 is shown. Figure 8 and Figure 13 As shown, the first connector 110 has a third limiting surface 1112 formed on the side near the endoscope 300, and the second connector 120 has a fourth limiting surface 1212 formed on the side of the insertion portion 121 near the second fixing portion 122. (Continue to see...) Figure 8 and Figure 13 The third limiting surface 1112 can be one surface, two surfaces, or three surfaces; correspondingly, the number of the fourth limiting surfaces 1212 matches the number of the third limiting surfaces 1112.

[0040] In this embodiment, when the movable connecting buckle 100, the insertion part 121 and the guide part 111 are inserted and engaged, the insertion length of the insertion part 121 can be controlled by the abutment of the third limiting surface 1112 and the fourth limiting surface 1212, thereby positioning the negative pressure nozzle 311 and avoiding the problem that the negative pressure nozzle 311 is not deeply inserted, which would make it difficult for the negative pressure nozzle 311 to engage with the fixing member 130.

[0041] Not limited to this, the insertion length of the insertion part 121 can also be limited by other structures.

[0042] In some embodiments, there are two guide portions 111 and two insertion portions 121, and the guide portions 111 or insertion portions 121 are located on both sides of the negative pressure nozzle 311, such as... Figure 5 and Figure 14 As shown. In this embodiment, the movable connecting buckle 100, by providing two guide parts 111 and a plug-in part 121, can further improve the reliability of the plug-in part 121 and the guide part 111 in guiding the negative pressure nozzle 311.

[0043] In some embodiments, the first connector 110 or the second connector 120 connected to the sampling device 200 is further provided with a socket 112, such as Figure 10 and Figure 11 As shown. The insertion hole 112 is connected to the collection port 221. Preferably, when the insertion part 121 and the guide part 111 are inserted, the central axis of the insertion hole 112 coincides with the central axis of the negative pressure nozzle 311. This allows the negative pressure nozzle 311 to be accurately inserted into the insertion hole 112 as the insertion part 121 moves in the insertion direction. After the insertion part 121 and the guide part 111 are properly inserted, the negative pressure nozzle 311 is inserted into the insertion hole 112. Figure 11 As shown, a sealing element 1121 is also provided at the insertion hole 112. The sealing element 1121 can seal the negative pressure nozzle 311 to the first connector 110, avoiding the potential risk of the sample overflowing from the end of the negative pressure nozzle 311.

[0044] In some embodiments, the movable connecting buckle 100 further includes a fastener 130, such as Figure 2 As shown. After the negative pressure nozzle 311 is inserted into the socket 112, the fixing member 130 engages with the first connecting member 110 and / or the second connecting member 120, and limits the negative pressure nozzle 311 by the fixing member 130. In this embodiment, the movable connecting buckle 100, through the fixing member 130, can not only fix the first connecting member 110 and the second connecting member 120 to prevent them from moving, but also limit the negative pressure nozzle 311 to prevent it from detaching from the first connecting member 110.

[0045] For example, the fixing member 130 has a first fixing block 131 and a second fixing block 132 disposed opposite to each other. One of a protrusion 1311 and a groove 3111 is provided on the opposite side of the first fixing block 131 and the second fixing block 132. The negative pressure nozzle 311 is provided with the other of a protrusion 1311 and a groove 3111. Figure 6 and Figure 7 , Figure 15 and Figure 16 As shown, a protrusion 1311 is provided on one side of the first fixing block 131 and the second fixing block 132 opposite to each other, and a groove 3111 is provided on the negative pressure nozzle 311. When the fixing member 130 is engaged with the first connecting member 110 and / or the second connecting member 120, the first fixing block 131 and the second fixing block 132 are located on both sides of the negative pressure nozzle 311, and the protrusion 1311 is engaged with the groove 3111, as shown. Figure 7 As shown. This can limit the axial movement of the negative pressure nozzle 311 and prevent it from detaching from the first connector 110.

[0046] See you again Figure 15As shown, a locking block 133 is also provided between the first fixing block 131 and the second fixing block 132, and an arc-shaped groove 1331 is formed on the locking block 133. When the fixing member 130 is engaged with the first connecting member 110 and / or the second connecting member 120, the locking block 133 is engaged above the negative pressure nozzle 311. This can limit the radial movement of the negative pressure nozzle 311 and further prevent the negative pressure nozzle 311 from disengaging from the first connecting member 110.

[0047] See also Figure 8 and Figure 9 , Figure 15 and Figure 16 As shown, the fixing member 130 is also provided with a fixing post 134, and the first connecting member 110 is provided with a fixing hole 115. When the fixing member 130 covers the first connecting member 110 and the second connecting member 120, the fixing post 134 and the fixing hole 115 are inserted and engaged; at the same time, the fixing member 130 generates a compressive force on the first connecting member 110 and the second connecting member 120. Thus, the first connecting member 110 and the second connecting member 120 can be fixed by the fixing member 130, while limiting the negative pressure nozzle 311.

[0048] The second aspect of this embodiment provides a detailed description of the sampling component.

[0049] The sampling component in this embodiment includes a sampling device 200, such as... Figure 2 As shown. The sampling device 200 includes a sampling bottle 210 and a cap 220, with the cap 220 covering the opening of the sampling bottle 210. Specifically, the structure of the sampling device 200 can be the same as that of the prior art, and will not be described in detail here.

[0050] The sampling component in this embodiment also includes a movable connecting buckle 100, such as... Figure 2 As shown. The movable connecting buckle 100 is a movable connecting buckle according to any of the technical solutions in the first aspect of this embodiment. The first connecting member 110 or the second connecting member 120 of the movable connecting buckle 100 is connected to the cover 220. The other of the first connecting member 110 and the second connecting member 120 is used to connect to the handle 310 of the endoscope 300.

[0051] The sampling component of this embodiment has a movable connecting buckle 100 according to any of the technical solutions in the first aspect of this embodiment. While realizing the connection between the sampling device 200 and the endoscope 300, the insertion action of the negative pressure nozzle 311 can be guided by the cooperation of the insertion part 121 and the guide part 111 of the movable connecting buckle 100, so that the negative pressure nozzle 311 can be quickly aligned with the collection port 221 of the sampling device 200 and inserted into place, thereby improving the accuracy and smoothness of the assembly of the sampling device 200.

[0052] The third aspect of this embodiment provides a detailed description of the endoscope system.

[0053] The endoscopic system of this embodiment includes a sampling device 200 and an endoscope 300, such as Figure 1 As shown. The sampling device 200 and endoscope 300 can have the same structure as those in the prior art, and will not be described in detail here.

[0054] The endoscope system of this embodiment also includes a movable connecting buckle 100, such as... Figure 1 As shown. The movable connecting buckle 100 is a movable connecting buckle of any of the technical solutions in the first aspect of this embodiment. The movable connecting buckle 100 is used to connect the sampling device 200 and the endoscope 300. For example, the first connecting member 110 of the movable connecting buckle 100 is connected to the sampling device 200, and the second connecting member 120 is connected to the handle 310 of the endoscope 300.

[0055] The endoscope system of this embodiment has a movable connecting buckle 100 according to any of the technical solutions in the first aspect of this embodiment. While realizing the connection between the sampling device 200 and the endoscope 300, the insertion action of the negative pressure nozzle 311 can be guided by the cooperation of the insertion part 121 and the guide part 111 of the movable connecting buckle 100, so that the negative pressure nozzle 311 can be quickly aligned with the collection port 221 of the sampling device 200 and inserted into place, thereby improving the accuracy and smoothness of the assembly of the sampling device 200.

[0056] The fourth aspect of this embodiment describes in detail the assembly method of the endoscope system.

[0057] The assembly method of the endoscope system of any of the aforementioned technical solutions includes the following steps: Step 100-1: Connect one of the first connector 110 and the second connector 120 to the sampling device 200. For example, the first connector 110 is connected to the sampling device 200.

[0058] Step 200-1: With the insertion part 121 and the guide part 111 in the inserted state, move the insertion part 121 and / or the guide part 111 to increase the distance between the first connector 110 and the second connector 120. For example, after the first connector 110 and the second connector 120 are inserted and engaged, the first connector 110 is then connected to the sampling device 200. For example, the first connector 110 can also be connected to the sampling device 200 first, and then the first connector 110 and the second connector 120 are inserted and engaged.

[0059] The movable insertion part 121 and / or guide part 111 are moved, and the distance between the first connector 110 and the second connector 120 is increased to provide clearance space for the endoscope 300, so that the endoscope 300 can be easily assembled and fixed with the second connector 120.

[0060] Step 300-1: Connect the other of the first connector 110 and the second connector 120 to the handle 310 of the endoscope 300. For example, the second connector 120 is connected to the handle 310 of the endoscope 300.

[0061] Step 400-1: Move the insertion part 121 and / or the guide part 111 to reduce the distance between the first connector 110 and the second connector 120, while simultaneously connecting the negative pressure nozzle 311 to the collection port 221 on the sampling device 200. For example, by moving the insertion part 121 again along the insertion direction, the distance between the first connector 110 and the second connector 120 is reduced, which guides the insertion of the negative pressure nozzle 311, allowing it to be quickly aligned and inserted into place with the collection port 221 of the sampling device 200, thus improving the accuracy and smoothness of the assembly of the sampling device 200.

[0062] This embodiment also provides another assembly method for the endoscope system.

[0063] The assembly method of the endoscope system of any of the aforementioned technical solutions includes the following steps: Step 100-2: Connect one of the first connector 110 and the second connector 120 to the sampling device 200, and the other to the handle 310 of the endoscope 300. For example, the first connector 110 is connected to the sampling device 200, and the second connector 120 is connected to the handle 310 of the endoscope 300.

[0064] Step 200-2: Connect the plug part 121 to the guide part 111, move the plug part 121 and / or the guide part 111, and reduce the distance between the first connector 110 and the second connector 120, while connecting the negative pressure nozzle 311 to the collection port 221 on the sampling device 200.

[0065] For example, after the plug-in part 121 and the guide part 111 are plugged in and engaged, moving the plug-in part 121 and the guide part 111 simultaneously, or moving only the plug-in part 121 or the guide part 111, can reduce the distance between the first connector 110 and the second connector 120 while guiding the insertion of the negative pressure nozzle 311. This allows the negative pressure nozzle 311 to be quickly aligned with the collection port 221 of the sampling device 200 and inserted into place, improving the accuracy and smoothness of the assembly of the sampling device 200.

[0066] In this embodiment, the assembly method of the endoscope system involves pre-assembling the first connector 110 and the second connector 120 onto the sampling device 200 when connecting the endoscope 300 and the sampling device 200. Then, by increasing the distance between the first connector 110 and the second connector 120, installation space is provided for the negative pressure nozzle 311. The endoscope 300 is then fixed to the second connector 120, and finally, the insertion of the negative pressure nozzle 311 is guided by the movement of the insertion part 121. Alternatively, when connecting the endoscope 300 and the sampling device 200, the first connector 110 and the second connector 120 are connected to the handle 310 of the sampling device 200 and the endoscope 300, respectively, and then the first connector 110 and the second connector 120 are connected. Similarly, the insertion of the negative pressure nozzle 311 is guided by the movement of the insertion part 121.

[0067] As can be seen, the assembly method of the endoscope system in this embodiment, after completing the insertion of the negative pressure nozzle 311, also includes the step of installing the fixing member 130 to fix the sampling device 200 and the endoscope 300.

[0068] The assembly method of the endoscope system in this embodiment provides two assembly methods when connecting the sampling device 200 and the endoscope 300 to meet different assembly requirements. Moreover, both assembly methods can guide the insertion of the negative pressure nozzle 311 through the cooperation of the insertion part 121 and the guide part 111, so that the negative pressure nozzle 311 can be quickly aligned with the collection port 221 of the sampling device 200 and inserted into place, improving the accuracy and smoothness of the assembly of the sampling device 200.
