[0096] The embodiment of the present application provides an assembly device 10, which is used to assemble a clamp assembly 30 and a conveying device 40. The assembly device 10 can accurately align the conveying device 40 and the clamp assembly 30, thereby improving assembly efficiency.

[0097] Please also refer to Figure 1 、 Figure 2 and Figure 3In the assembly device 10 provided in the first embodiment of the present application, the shell assembly 100 includes a first shell 110 and a second shell 120, and the first shell 110 and the second shell 120 are detachably connected by means of a buckle and a slot that cooperate with each other. In this embodiment, the shell assembly 100 is set as two parts that are detachably connected, which can facilitate the opening of the shell assembly 100, and then facilitate the placement of the clip assembly 30 in the receiving groove 130 inside the shell assembly 100 and fix it. It can be understood that the first shell 110 and the second shell 120 of the shell assembly 100 can also be connected by bolts, plug-in, etc. In addition, in some other embodiments, the shell assembly 100 can also be set as an integrated structure, that is, the shell assembly 100 is integrally formed, and an opening is opened on it that is connected to the internal receiving groove 130, and the clip assembly 30 can be placed in the receiving groove 130 through the opening.

[0098] See also Figure 2 The receiving groove 130 and the assembly groove 140 are formed inside the housing assembly 100. The receiving groove 130 is used to accommodate the clip assembly 30, and the assembly groove 140 is used to insert the conveying device 40 into the receiving groove 130. Specifically, the receiving groove 130 and the assembly groove 140 extend in the same direction, which is denoted as the first direction X. The arrow marked X in the drawings indicates the first direction X, which can correspond to the length direction of the housing assembly 100. The receiving groove 130 and the assembly groove 140 are arranged sequentially along the first direction X.

[0099] The shell assembly 100 is provided with an opening, which is provided on a side of the assembly groove 140 away from the receiving groove 130. Figure 3 The delivery device 40 can be inserted into the assembly groove 140 from the opening, and inserted into the receiving groove 130 along the assembly groove 140 so as to be connected with the clip assembly 30.

[0100] The side wall of the assembly groove 140 near the opening is set as a guide surface 141. From the opening to the inside, the size of the guide surface 141 decreases and is roughly conical. The guide surface 141 can guide the conveying device 40 so that it can be accurately inserted into the assembly device 10.

[0101] The positioning assembly 200 is connected to the housing assembly 100 and includes a first positioning portion 210 and a second positioning portion 220 that are oppositely disposed. The first positioning portion 210 and the second positioning portion 220 are disposed between the receiving groove 130 and the assembly groove 140. Figure 3 The first positioning portion 210 and the second positioning portion 220 are used to cooperate with the matching portion 410 of the conveying device 40 when the conveying device 40 is inserted into the accommodating groove 130 to position the conveying device 40 so that the conveying device 40 can be accurately aligned with the clamp assembly 30 to facilitate efficient assembly.

[0102] For more details, please refer again to Figure 2 The first shell 110 of the shell assembly 100 includes a first bearing portion 150 and a second bearing portion 160. The first bearing portion 150 and the second bearing portion 160 are protruding structures provided on the inner wall of the first shell 110. The first bearing portion 150 and the second bearing portion 160 are arranged in sequence along the first direction X and are spaced apart from each other. The accommodating groove 130 is a groove structure formed on the first bearing portion 150, and the assembly groove 140 is a groove structure formed on the second bearing portion 160. The first positioning portion 210 and the second positioning portion 220 are located between the first bearing portion 150 and the second bearing portion 160 and are arranged relative to each other in the second direction Y. The first direction X and the second direction Y are perpendicular to each other. The arrow marked Y in the drawings indicates the second direction Y. In this embodiment, the second direction Y can correspond to the width direction of the shell assembly 100. It will be understood that the "relative" in the relative arrangement of the first positioning portion 210 and the second positioning portion 220 means that the first positioning portion 210 and the second positioning portion 220 face each other in space.

[0103] like Figure 3 As shown, the clamp assembly 30 can be placed in the receiving groove 130, and its clamp seat 31 is arranged toward the side where the assembly groove 140 is located, so as to facilitate the connection of the conveying device 40. Figure 2 A limiting protrusion 190 is further provided in the receiving groove 130. The limiting protrusion 190 is used to limit the position of the clip assembly 30 so that the clip assembly 30 can be stably placed in the receiving groove 130. When the clip assembly 30 is placed in the receiving groove 130, the limiting protrusion 190 abuts against the side of the clip seat 31 away from the second supporting portion 160 to limit the position of the clip assembly 30.

[0104] The conveying device 40 passes through the gap between the first positioning portion 210 and the second positioning portion 220 via the assembly slot 140 and is inserted into the receiving slot 130. In this case, the first positioning portion 210 and the second positioning portion 220 can cooperate with the matching portion 410 provided on the transition cap of the conveying device 40, thereby positioning the conveying device 40, allowing the conveying device 40 to be quickly aligned with the clamp assembly 30, thereby improving the assembly efficiency of the two.

[0105] In the first embodiment, the matching portion 410 can be an annular groove provided on the transition cap of the conveying device 40, and the first positioning portion 210 and the second positioning portion 220 can be embedded in the annular groove to cooperate with the conveying device 40 to position the conveying device 40. Alternatively, in other embodiments, the matching portion 410 can be a protrusion (protruding outward) provided on the transition cap, and the first positioning portion 210 and the second positioning portion 220 are configured as a groove structure that can cooperate with the protrusion, that is, the surfaces of the first positioning portion 210 and the second positioning portion 220 that contact the matching portion 410 are configured as grooves, and the matching is achieved by embedding the protrusion into the groove; alternatively, the matching portion 410 can be a positioning hole provided on the transition cap, and the first positioning portion 210 and the second positioning portion 220 are configured to be embedded in the positioning hole to achieve matching; alternatively, the matching portion 410 can be a notch formed on the surface of the transition cap, and the first positioning portion 210 and the second positioning portion 220 are configured to be able to snap into the notch to achieve matching.

[0106] Please also refer to Figures 2 to 5 In the first embodiment, the positioning assembly 200 further includes a first elastic portion 230 and a second elastic portion 240. The first positioning portion 210 is connected to the shell assembly 100 via the first elastic portion 230, and the second positioning portion 220 is connected to the shell assembly 100 via the second elastic portion 240. The first elastic portion 230 and the second elastic portion 240 are configured to be elastically deformable. When the positioning assembly 200 is subjected to pressure, the first elastic portion 230 and the second elastic portion 240 are elastically deformed to enable the first positioning portion 210 and the second positioning portion 220 to move.

[0107] During the process of inserting the conveying device 40 into the receiving groove 130 through the assembly groove 140, the transition cap of the conveying device 40 contacts and presses the first positioning portion 210 and the second positioning portion 220. The positioning assembly 200 receives the squeezing force from the conveying device 40 and transmits it to the first elastic portion 230 and the second elastic portion 240, causing both to elastically deform in the second direction Y. This in turn drives the first positioning portion 210 and the second positioning portion 220 away from each other in the second direction Y, allowing the conveying device 40 to smoothly pass through the first positioning portion 210 and the second positioning portion 220 and be inserted into the receiving groove 130. As the conveying device 40 continues to move, the first positioning portion 210 and the second positioning portion 220 cooperate with the mating portion 410 to position the conveying device 40 so that the conveying device 40 can be assembled with the clamp assembly 30.

[0108] See also Figure 4In the first embodiment, the first elastic portion 230 and the second elastic portion 240 are respectively disposed on both sides of the first bearing portion 150 in the second direction Y. In the second direction Y, both the first elastic portion 230 and the second elastic portion 240 have movable gaps 270 on either side, allowing the first elastic portion 230 and the second elastic portion 240 to deform toward the movable gaps 270 on either side. The transition cap of the conveying device 40 contacts and presses the first positioning portion 210 and the second positioning portion 220, causing the first elastic portion 230 and the second elastic portion 240 to elastically deform toward the movable gaps 270 on either side, thereby driving the first positioning portion 210 and the second positioning portion 220 away from each other in the second direction Y.

[0109] When the first positioning portion 210 and the second positioning portion 220 cooperate with the matching portion 410, due to the elastic recovery ability of the first elastic portion 230 and the second elastic portion 240, the first positioning portion 210 and the second positioning portion 220 can squeeze the matching portion 410, thereby improving the stability of the cooperation between the first positioning portion 210 and the second positioning portion 220 and the matching portion 410.

[0110] Please also refer to Figure 4 、 Figure 5 and Figure 6 In the first embodiment, the positioning assembly 200 and the first shell 110 are an integrated structure, that is, the first positioning portion 210, the second positioning portion 220, the first elastic portion 230, the second elastic portion 240 and the first shell 110 are an integral whole, which can be integrally formed by injection molding, 3D printing, or other processing methods. For an integrated structure, it can effectively improve structural stability and reduce processing difficulty. In addition, for an integrated structure, the movable gap 270 on both sides of the first elastic portion 230 and the second elastic portion 240 can reduce the rigidity of the structure at this position, improve the elastic deformation ability of the first elastic portion 230 and the second elastic portion 240, and facilitate the insertion of the conveying device 40.

[0111] Please refer again Figure 6 In the first embodiment, a groove structure is provided on the inner wall of the second housing 120 facing the first housing 110, which is opposite to the receiving groove 130 and the assembly groove 140. This groove structure can cooperate with the receiving groove 130 and the assembly groove 140 to more stably place the clip assembly 30 in the housing assembly 100 and more stably guide the conveying device 40.

[0112] Please also refer to Figure 7 and Figure 8In the first embodiment, the first positioning portion 210 and / or the second positioning portion 220 have a first chamfered surface 250 on the side close to the assembly groove 140. When the conveying device 40 moves toward the receiving groove 130 via the assembly groove 140, the first chamfered surface 250 can contact the conveying device 40. By providing the first chamfered surface 250 on the side of the first positioning portion 210 and / or the second positioning portion 220 facing the assembly groove 140, on the one hand, the first chamfered surface 250 can be used to guide the conveying device 40, so that the conveying device 40 can be inserted into the receiving groove 130 more accurately; on the other hand, the conveying device 40 squeezes the first chamfered surface 250, which makes it easier to move the first positioning portion 210 and the second positioning portion 220 away from each other, so that the conveying device 40 can be inserted into the receiving groove 130 more smoothly. The operator can directly insert the delivery device 40 into the receiving groove 130 and connect it to the clamp assembly 30, thereby improving the accuracy and efficiency of assembling the delivery device 40 and the clamp assembly 30 and facilitating the operation of medical personnel. Optionally, the first positioning portion 210 and the second positioning portion 220 both have a first chamfered surface 250.

[0113] Please refer again Figure 8 The first positioning portion 210 and / or the second positioning portion 220 have a second chamfered surface 260 on the side near the receiving groove 130. When the conveying device 40 moves from the receiving groove 130 toward the assembly groove 140, the second chamfered surface 260 can contact the conveying device 40. By providing the second chamfered surface 260 on the side of the first positioning portion 210 and / or the second positioning portion 220 facing the receiving groove 130, after the conveying device 40 and the clamp assembly 30 are connected, the connected conveying device 40 and the clamp assembly 30 can be directly removed from the assembly device 10, reducing the resistance of the first positioning portion 210 and the second positioning portion 220. Optionally, both the first positioning portion 210 and the second positioning portion 220 have the second chamfered surface 260.

[0114] Among them, setting the first chamfered surface 250 and the second chamfered surface 260 can facilitate the insertion or extraction of the conveying device 40 into or out of the assembly device 10. According to actual clinical needs, after setting the first chamfered surface 250 and the second chamfered surface 260, the force required for the insertion or extraction of the conveying device 40 may not exceed 50N.

[0115] Please also refer to Figure 9 、 Figure 10 and Figure 11, the structure of the second embodiment of the present application is similar to that of the first embodiment. In the second embodiment, the shell assembly 100 is also provided with two parts, a first shell 110 and a second shell 120, which are detachably connected by means of buckles and slots that cooperate with each other. A first bearing portion 150 and a second bearing portion 160 arranged along the first direction X and spaced apart from each other are provided on the inner wall of the first shell 110, a receiving groove 130 is formed on the first bearing portion 150, and an assembly groove 140 is formed on the second bearing portion 160. The first positioning portion 210 and the second positioning portion 220 are provided between the first bearing portion 150 and the second bearing portion 160, and are arranged relative to each other along the second direction Y.

[0116] See also Figure 12 and Figure 13 In the second embodiment, the first elastic portion 230 and the second elastic portion 240 are disposed in slightly different positions than in the first embodiment. They are disposed on both sides of the second supporting portion 160 in the second direction Y. The first elastic portion 230 and the second elastic portion 240 are respectively connected to the sidewalls of the first housing 110 , and a movable gap 270 is defined between the first supporting portion 150 and the second supporting portion 160 .

[0117] Please also refer to Figure 13 and Figure 14 In the second embodiment, the first positioning portion 210 and the second positioning portion 220 have a first chamfered surface 250 on one side near the assembly groove 140. This allows the operator to directly insert the delivery device 40 into the receiving groove 130 and connect it to the clamp assembly 30, thereby improving the accuracy and efficiency of assembling the delivery device 40 and the clamp assembly 30 and facilitating the operation of medical personnel.

[0118] Please also refer to Figures 15 to 19 , different from the first embodiment, in the second embodiment, the second shell 120 includes a pressing portion 121, which can apply pressure to the positioning assembly 200 through the pressing portion 121, so that the first positioning portion 210 and the second positioning portion 220 are separated from each other. In this embodiment, the second shell 120 and the positioning assembly 200 are arranged relative to each other in the third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The arrow marked Z in the accompanying drawings indicates the third direction Z, and the third direction Z can correspond to the thickness direction of the shell assembly 100. The pressing portion 121 of the second shell 120 can be pressed to move toward the positioning assembly 200, contact the positioning assembly 200, and apply pressure to the positioning assembly 200, so that the first positioning portion 210 and the second positioning portion 220 can be separated from each other in the second direction Y, and then the two are detached from the mating portion 410. In this way, the connected conveying device 40 and the clamp assembly 30 can be smoothly pulled out from the assembly device 10, facilitating the assembly operation.

[0119] For more details, please refer again to Figure 9 The second shell 120 is provided with a first slot 1210 and a second slot 1211. The first slot 1210 and the second slot 1211 change the structural rigidity between the two, so that a movable pressing portion 121 is formed between the two, and the pressing portion 121 can be elastically deformed when pressed. The second shell 120 also has an avoidance portion 122, which is arranged on the inner side of the pressing portion 121, and the second slot 1211 is provided between the two. The avoidance portion 122 is arranged relative to the first bearing portion 150 in the third direction Z, and a groove structure is provided on the side facing the first bearing portion 150. The groove structure is opposite to the accommodating groove 130 and cooperates with each other, so that the clip assembly 30 is placed more firmly. By providing the avoidance portion 122 and providing the second slot 1211 to separate the connection between the avoidance portion 122 and the pressing portion 121, when the pressing portion 121 is pressed and displaced, it can avoid the clip assembly 30 and avoid squeezing the clip assembly 30.

[0120] Please also refer to Figure 17 、 Figure 18 and Figure 19 The pressing portion 121 is provided with a first boss 123 and a second boss 124 that protrude toward the positioning assembly 200. When the pressing portion 121 moves toward the positioning assembly 200, the first boss 123 and the second boss 124 can move toward between the first positioning portion 210 and the second positioning portion 220, and the first boss 123 can press the first positioning portion 210, and the second boss 124 can press the second positioning portion 220, so that the first positioning portion 210 and the second positioning portion 220 can separate from each other in the second direction Y.

[0121] The first boss 123 has a first contact surface 1231 for contacting and pressing the first positioning portion 210; the second boss 124 has a second contact surface 1241 for contacting and pressing the second positioning portion 220. Figure 19 As shown, the first contact surface 1231 and the second contact surface 1241 are both inclined surfaces; Figure 20 As shown, both the first contact surface 1231 and the second contact surface 1241 are arcuate surfaces. By configuring the contact surface between the first boss 123 and the first positioning portion 210, and the contact surface between the second boss 124 and the second positioning portion 220 to be inclined or arcuate surfaces, as the pressing depth increases, the first contact surface 1231 presses the first positioning portion 210, and the second contact surface 1241 presses the second positioning portion 220 more, allowing the first positioning portion 210 and the second positioning portion 220 to move away from each other.

[0122] Please refer again Figure 14At least a portion of the first positioning portion 210 protrudes relative to the first elastic portion 230 toward the pressing portion 121, and at least a portion of the second positioning portion 220 protrudes relative to the second elastic portion 240 toward the pressing portion 121. This allows the pressing portion 121 to apply a compressive force to the first positioning portion 210 and the second positioning portion 220.

[0123] Please also refer to Figure 21 、 Figure 22 and Figure 23 In the third embodiment of the present application, the first elastic portion 230 and the first positioning portion 210 are disposed on the first shell 110 , and the second elastic portion 240 and the second positioning portion 220 are disposed on the second shell 120 .

[0124] Specifically, the first housing 110 is connected to the first elastic portion 230. The first housing 110 includes a first supporting portion 150 and a second supporting portion 160. The first supporting portion 150 and the second supporting portion 160 are arranged in a first direction X and spaced apart from each other. The first positioning portion 210 is disposed between the first supporting portion 150 and the second supporting portion 160. The first elastic portion 230 penetrates the first supporting portion 150 in the first direction X and is connected to the first positioning portion 210.

[0125] The second housing 120 is connected to the second elastic portion 240. The second housing 120 includes a third supporting portion 170 and a fourth supporting portion 180. The third supporting portion 170 and the fourth supporting portion 180 are arranged in a parallel relationship in the first direction X and are spaced apart from each other. The second positioning portion 220 is disposed between the third supporting portion 170 and the fourth supporting portion 180. The second elastic portion 240 passes through the third supporting portion 170 in the first direction X and is connected to the second positioning portion 220.

[0126] Please also refer to Figures 24 to 26 In the third embodiment, the first supporting portion 150 and the third supporting portion 170 are arranged opposite to each other and enclose the receiving groove 130. The clip assembly 30 is placed in the receiving groove 130 between the first supporting portion 150 and the third supporting portion 170, and is clamped by the first supporting portion 150 and the third supporting portion 170. Figure 23 The second supporting portion 160 and the fourth supporting portion 180 are arranged opposite to each other and enclose the assembly groove 140. The conveying device 40 can be inserted from the assembly groove 140 between the second supporting portion 160 and the fourth supporting portion 180 into the receiving groove 130 to connect with the clamp assembly 30.

[0127] like Figure 26 As shown, when the conveying device 40 is inserted into the receiving groove 130 through the assembly groove 140, the conveying device 40 passes through the gap between the first positioning portion 210 and the second positioning portion 220. The first positioning portion 210 and the second positioning portion 220 can cooperate with the matching portion 410 to position the conveying device 40.

[0128] Please also refer to Figure 27 、 Figure 28 and Figure 29 In the third embodiment, the first elastic portion 230 is provided with a first supporting structure 231. When pressed, the first elastic portion 230 can rotate around the first supporting structure 231 to drive the first positioning portion 210 to move. The second elastic portion 240 is provided with a second supporting structure 241. When pressed, the second elastic portion 240 can rotate around the second supporting structure 241 to drive the second positioning portion 220 to move.

[0129] Specifically, the end of the first elastic portion 230 away from the first positioning portion 210 is connected to the first housing 110, and the end of the second elastic portion 240 away from the second positioning portion 220 is connected to the second housing 120. The first support structure 231 is a protrusion provided by the first elastic portion 230 toward the second elastic portion 240, and the second support structure 241 is a protrusion provided by the second elastic portion 240 toward the first elastic portion 230. The first support structure 231 and the second support structure 241 are arranged opposite each other in the third direction Z. When the first elastic portion 230 and the second elastic portion 240 are pressed, the first support structure 231 and the second support structure 241 contact each other. As a result, the first support structure 231 and the second support structure 241 support each other, forming a fulcrum. The first elastic portion 230 and the second elastic portion 240 can each rotate about the fulcrum, thereby respectively driving the first positioning portion 210 and the second positioning portion 220 to move, causing them to separate from each other in the third direction Z, thereby disengaging them from the mating portion 410. In this way, the connected conveying device 40 and the clamp assembly 30 can be smoothly pulled out from the assembling device 10 .

[0130] like Figure 28 As shown, in the third embodiment, the first elastic portion 230 includes a first pressing plate 232 and a first connecting rod 233. The first pressing plate 232 is configured as a structure that can be pressed by a finger. It is located on the side of the first bearing portion 150 away from the first positioning portion 210, and its end away from the first bearing portion 150 is connected to the first housing 110. In the first direction X, the first pressing plate 232, the first connecting rod 233, and the first positioning portion 210 are arranged in sequence, and the first connecting rod 233 connects the first pressing plate 232 and the first positioning portion 210. Specifically, the first connecting rod 233 passes through the first bearing portion 150 in the first direction X to connect the first pressing plate 232 and the first positioning portion 210 located on both sides of the first bearing portion 150.

[0131] It can be understood that in this embodiment, the first bearing part 150 includes two parts spaced apart from each other in the second direction Y, and groove structures are respectively provided on these two parts, and the respective groove structures and the groove structure of the third bearing part 170 together form an accommodating groove 130, and the first connecting rod 233 is arranged between the two parts and passes through the first bearing part 150 in the first direction X.

[0132] In the third embodiment, the first supporting structure 231 is provided on the first pressing plate 232 . Specifically, the first supporting structure 231 is provided at the connection between the first pressing plate 232 and the first connecting rod 233 , and protrudes toward the second elastic portion 240 .

[0133] like Figure 29 As shown, in the third embodiment, the second elastic portion 240 includes a second pressing plate 242 and a second connecting rod 243. The second pressing plate 242 is configured to be pressed by a finger. It is located on the side of the third supporting portion 170 away from the second positioning portion 220, and its end away from the third supporting portion 170 is connected to the second housing 120. In the first direction X, the second pressing plate 242, the second connecting rod 243, and the second positioning portion 220 are arranged in sequence, and the second connecting rod 243 connects the second pressing plate 242 and the second positioning portion 220. Specifically, the second connecting rod 243 penetrates the third supporting portion 170 in the first direction X to connect the second pressing plate 242 and the second positioning portion 220 located on both sides of the third supporting portion 170.

[0134] It can be understood that in this embodiment, the third bearing part 170 also includes two parts spaced apart from each other in the second direction Y, and groove structures are respectively provided on these two parts, and the respective groove structures and the groove structure of the first bearing part 150 are used to jointly form an accommodating groove 130, and the second connecting rod 243 is arranged between the two parts and passes through the third bearing part 170 in the first direction X.

[0135] In the third embodiment, the second supporting structure 241 is disposed on the second pressing plate 242 . Specifically, the second supporting structure 241 is disposed at the connection between the second pressing plate 242 and the second connecting rod 243 , and protrudes toward the first elastic portion 230 .

[0136] When the clamp assembly 30 and the conveying device 40 are assembled, the first pressing plate 232 and the second pressing plate 242 are pressed together, and the first pressing plate 232 and the second pressing plate 242 are pressed together, causing the first connecting rod 233 to rotate about the first supporting structure 231, and the second connecting rod 243 to rotate about the second supporting structure 241, thereby driving the first positioning portion 210 and the second positioning portion 220 to move away from each other, thereby disengaging the first positioning portion 210 and the second positioning portion 220 from the mating portion 410. In this way, the conveying device 40 and the clamp assembly 30 can be smoothly removed from the assembly device 10.

[0137] Please refer again Figure 23 and Figure 26 The first positioning portion 210 and the second positioning portion 220 have a first dimension L1, and the mating portion 410 has a second dimension L2; L1 < L2. Specifically, the limiting gap formed between the first positioning portion 210 and the second positioning portion 220 presents a quasi-circular channel structure, whose minimum inner diameter is defined as the first dimension L1. The mating portion 410 is correspondingly configured to be roughly cylindrical, and the measured outer diameter in the same direction is the second dimension L2. When the mating portion 410 is inserted into the limiting gap along the first direction X, due to the dimension setting of L2 > L1, the outer surface of the mating portion 410 will produce interference with the contact surfaces of the first positioning portion 210 and the second positioning portion 220. At this time, the first positioning portion 210 and the second positioning portion 220 expand outward through elastic deformation, and the rebound force generated by the expansion forms a radial clamping force. This clamping force acts together with the friction force in the insertion direction to achieve reliable locking of the conveying device 40.

[0138] Please also refer to Figures 30 to 35 The structure of the fourth embodiment of the present application is substantially the same as that of the third embodiment, except that, in the fourth embodiment, the first elastic portion 230 is connected to the first housing 110 via the first supporting structure 231, and the second elastic portion 240 is connected to the second housing 120 via the second supporting structure 241. In other words, in the fourth embodiment, the first supporting structure 231 and the second supporting structure 241 are no longer configured as mutually cooperating protruding structures. Instead, the connection between the first elastic portion 230 and the first housing 110 is used as the first supporting structure 231, and the connection between the second elastic portion 240 and the second housing 120 is used as the second supporting structure 241. By using the connection as a fulcrum, when the first elastic portion 230 and the second elastic portion 240 are pressed, they can respectively rotate around the fulcrum formed by the connection, that is, rotate around the first supporting structure 231 and the second supporting structure 241, respectively, to drive the first positioning portion 210 to move.

[0139] like Figure 34 As shown, both sides of the second connecting rod 243 are connected to the second housing 120 (specifically, to the two parts of the third bearing portion 170), and the connection point is the second support structure 241. Correspondingly, both sides of the first connecting rod 233 are connected to the first housing 110 (specifically, to the two parts of the first bearing portion 150), and the connection point is the first support structure 231.

[0140] The present application also provides a hemostatic clip kit, which includes a clip assembly 30, a delivery device 40, and an assembly device 10 as described in any of the above embodiments. The assembly device 10 is used to assemble the clip assembly 30 and the delivery device 40. The hemostatic clip kit can have all the technical features and effects of the above-described assembly device 10, which will not be repeated here.

[0141] The clamp assembly 30 , the conveying device 40 and the assembling device 10 can be stored and transported independently, or the clamp assembly 30 can be placed in the receiving groove 130 of the assembling device 10 .

[0142] The present application also provides an assembly method for the assembly device 10 of any of the above embodiments. Figure 1 Combined with Figure 11 、 Figure 12 、 Figure 36 and Figure 37 The assembly method includes: inserting the conveying device 40 into the assembly groove 140 through the opening of the shell component 100, and inserting it into the receiving groove 130 through the assembly groove 140, so that the positioning component 200 of the assembly device 10 cooperates with the matching part 410 of the conveying device 40, positioning the conveying device 40, and the clamp component 30 is accommodated in the receiving groove 130 in a closed state; operating the handle mechanism of the conveying device 40 to insert the cable component 42 of the conveying device 40 into the clamp seat 31 of the clamp component 30 and connect it with the clamp 32; by pulling the conveying device 40 out of the assembly device 10, the clamp component 30 is taken out together to complete the assembly.

[0143] Specifically, the sheath assembly 41 and cable assembly 42 of the delivery device 40 are inserted into the assembly slot 140 through the opening of the shell assembly 100, and then inserted into the receiving slot 130 through the assembly slot 140. The first positioning portion 210 and the second positioning portion 220 of the assembly device 10 are engaged with the mating portion 410 of the sheath assembly 41, thereby securing the distal transition cap of the sheath assembly 41. The handle mechanism of the delivery device 40 is manipulated to control the cable body 421 of the cable assembly 42 to move distally together with the transmission head 422, and the transmission head 422 is inserted into the clamp seat 31 to connect with the clamp 32. The closed state refers to the state in which the clip elements 322 of the clamp assembly 30 are clamped together.

[0144] like Figure 37 As shown, in some embodiments, the interior space of the clamp seat 31 includes a first section 311 and a second section 312 arranged sequentially along its axial direction. The first section 311 is located on the side of the second section 312 away from the clip element 322, and the radial dimension of the first section 311 is greater than the radial dimension of the second section 312. Here, "radial dimension" refers to the dimension of the internal profile of the structure in a direction perpendicular to the central axis of the clamp assembly 30; this radial dimension is independent of the cross-sectional shape of the clamp assembly 30 (e.g., circular, polygonal, or irregular), and is based solely on the central axis. For example, if the interior space is cylindrical, the radial dimension is the diameter; if the interior space is polygonal, the radial dimension is twice the perpendicular distance from the central axis to any sidewall.

[0145] When the clip assembly 30 is Figure 36 and Figure 37 The closed state shown is accommodated in the receiving groove 130, and the retaining portion 3212 in the retaining unit 3211 of the clamp 32 pull buckle 321 is located in the first section 311, so that the two sides of the retaining portion 3212 are not constrained by the clamp seat 31. During the insertion of the transmission head 422 into the pull buckle 321, the retaining portions 3212 are squeezed and can move away from each other, and the retaining units 3211 undergo elastic deformation, so that the cone head of the transmission head 422 can be stuck between the retaining units 3211 to achieve connection with the pull buckle 321. In addition, the cone head of the transmission head 422 is configured as a conical structure. When the transmission head 422 is inserted into the pull buckle 321, the conical surface of the cone head first contacts the pull buckle 321, which can play a guiding role. Therefore, the force required to insert the pull buckle 321 is very small, and it is relatively easy to insert into the pull buckle 321. When the transmission head 422 is pulled out from the pull buckle 321, there is no tapered surface to guide, so the pulling force is relatively large, which can ensure that the clip element 322 enters a locked state when clamping tissue.

[0146] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0147] The above is a detailed introduction to the assembly device 10 and the hemostatic clip kit provided in the embodiments of the present application, and specific examples are used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the technical solutions and core ideas of the present application; ordinary technicians in this field should understand that: they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
