Description

Technical Field

[0001] This invention relates to the field of interventional medicine, and more specifically to an adhesive filament system. Background Technology

[0002] Endovascular techniques are an emerging medical approach that utilizes a sheath to reach the lesion site (such as the coronary artery, carotid artery, celiac trunk, renal artery, etc.) along the lumen of a blood vessel, and then performs minimally invasive surgical treatment by implanting a stent, medication, or other implantable devices. The sheath serves as a tool to establish a channel from outside the body during endovascular surgery. Due to the variable and complex location of the openings of peripheral blood vessels of various levels, such as the iliac artery, femoral artery, common carotid artery, brachiocephalic trunk, and coronary arteries, to the aorta in actual clinical use, accurate localization presents certain challenges.

[0003] To address the aforementioned issues, adjustable bending sheaths have emerged on the market. These sheaths contain a traction wire, which is pulled to bend the distal end of the sheath, achieving the desired position and angle. The process of installing the traction wire into the sheath involves using a liner to attach the wire, then placing the sheath over the liner and heat-sealing the wire to the sheath. Finally, the liner is removed from the sheath. However, attaching the traction wire to the liner typically requires a ruler to ensure the wire is flush against the ruler before manually attaching it. This method often results in the wire not being perfectly straight, causing it to twist during bending and affecting both its bending function and aesthetics. Furthermore, manual attachment is inefficient and inefficient in terms of time and labor costs. Summary of the Invention

[0004] To overcome the problems existing in the prior art, the present invention provides a filament-adhesive system.

[0005] The present invention provides a wire-adhesive system for accurately adhering the traction wire of an adjustable bending sheath to a liner. The wire-adhesive system includes a wire-adhesive device and a liner. The traction wire is disposed on the liner. The wire-adhesive device includes a wire-adhesive platform and a clamping device. The wire-adhesive platform is provided with a receiving groove, in which the liner is housed. Part of the traction wire is housed in the clamping device, which is movable relative to the traction wire and the wire-adhesive platform along the axial direction of the liner.

[0006] In some embodiments of the present invention, the two adjacent sides of the side of the adhesive table where the receiving groove is provided are respectively provided with sliding grooves, and the clamping device includes a first sliding member and a second sliding member. The first sliding member and the second sliding member respectively cooperate with the sliding grooves provided on both sides of the adhesive table, and the first sliding member and the second sliding member can slide in the corresponding sliding grooves.

[0007] In some embodiments of the present invention, the clamping device includes a first clamping member and a second clamping member. The first clamping member cooperates with the first sliding member, and the second clamping member cooperates with the second sliding member. A gap is formed between the first clamping member and the second clamping member, and the traction wire is disposed in the gap.

[0008] In some embodiments of the present invention, the side of the first clamping member closest to the second clamping member is inclined toward the direction of the liner to form a first ramp structure, and the side of the second clamping member closest to the first clamping member is inclined toward the direction of the liner to form a second ramp structure.

[0009] In some embodiments of the present invention, a first storage groove is provided on the side of the first sliding member away from the adhesive table, and a second storage groove is provided on the side of the second sliding member away from the adhesive table. The side of the first clamping member close to the first sliding member is stored in the first storage groove, and the side of the second clamping member close to the second sliding member is stored in the second storage groove.

[0010] In some embodiments of the present invention, the clamping device further includes a mating member, which passes through the slide groove. The mating member includes a first mating portion, a second mating portion, and a limiting portion. The first mating portion and the second mating portion are respectively disposed at both ends of the mating member. The limiting portion is disposed between the first mating portion and the second mating portion. The first sliding member mates with the first mating portion, and the side of the first sliding member near the slide groove abuts against the limiting portion. The second sliding member mates with the second mating portion, and the side of the second sliding member near the slide groove abuts against the limiting portion.

[0011] In some embodiments of the present invention, the chute includes a through-groove structure that passes through two adjacent sides of the side of the adhesive table where the receiving groove is provided. The inner wall surface of the chute away from the liner protrudes in the direction of the liner to form a protrusion structure. The limiting part is recessed inward to form a groove structure. The protrusion structure cooperates with the groove structure. The cooperating part can move in the axial direction of the liner within the chute.

[0012] In some embodiments of the present invention, the side of the accommodating groove of the filament-adhesive table is inclined to the inner wall of the accommodating groove to form a third slope structure, and the inner wall surface of the accommodating groove away from the liner is provided with a traction wire accommodating groove for accommodating the traction wire.

[0013] In some embodiments of the present invention, the wire-adhesive device further includes an adapter, the adapter including an adapter part and a fixing member, the fixing member being fixed to the end of the wire-adhesive table, the fixing member having an adapter groove on the side near the liner, the adapter part being disposed in the adapter groove, the adapter part being movable within the adapter groove, the adapter part having an adapter hole on the side near the liner, one end of the liner being housed in the adapter hole.

[0014] In some embodiments of the present invention, the adapter further includes a first locking member and a second locking member. The first locking member is disposed on the side of the fixing member away from the adapter and passes through the fixing member to cooperate with the adapter. The second locking member is disposed on the side of the wire-adhesive table away from the fixing member and passes through the wire-adhesive table to cooperate with the fixing member.

[0015] Compared with existing technologies, the wire bonding system of the present invention has the following advantages: the wire bonding system ensures that the traction wire is bonded straight to the liner. This prevents the traction wire from being improperly positioned within the sheath, avoiding a twisted state during bending and affecting the bending function and aesthetics of the sheath. Furthermore, by bonding the traction wire to the liner in this manner, there is no need to visually inspect the straightness of the traction wire; the clamping device ensures the straightness of the traction wire, thereby improving product yield, increasing wire bonding efficiency, and reducing time and labor costs.

Detailed Implementation

[0027] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0028] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0029] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0030] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0031] To more clearly describe the structure of this application, the terms "proximal" and "distal" are used herein as conventional terms in the field of interventional medicine. Specifically, "distal" refers to the end furthest from the operator during the surgical procedure, "proximal" refers to the end closest to the operator during the surgical procedure, "axial" refers to its length direction, and "radial" refers to the direction perpendicular to the "axial".

[0032] Please see Figures 1-3 This invention provides a wire bonding system 100 for bonding the traction wire of an adjustable bendable sheath to a liner rod in a straight and accurate manner. The liner rod is used for shaping the sheath and for placing the traction wire inside the sheath. For example, the material for making the sheath is heat-melted onto the liner rod, and then the liner rod is pulled out of the sheath. At this time, the traction wire on the liner rod will remain inside the sheath, and after the liner rod is pulled out of the sheath, the sheath is shaped into a hollow tubular structure. The wire bonding system 100 includes a wire bonding device 1 and a liner rod 2, on which the traction wire 200 can be placed to facilitate subsequent bonding work. The wire-adhesive device 1 includes a wire-adhesive platform 11 and a clamping device 12. The wire-adhesive platform 11 is provided with a receiving groove 111, in which the liner 2 is housed. Part of the traction wire 200 is housed in the clamping device 12. The clamping device 12 can move relative to the traction wire 200 and the wire-adhesive platform 11 along the axial direction of the liner 2. Specifically, in a specific embodiment of the present invention, the wire-adhesive platform 11 has a cuboid structure, and the receiving groove 111 has a long, narrow groove structure, so that the receiving groove 111 can accommodate the entire liner 2. In the initial state, the clamping device 12 can be slid to the end of the liner 2. When it is necessary to adhere the traction wire 200 to the liner 2, one end of the traction wire 200 can be placed in the clamping device 12, and the remaining part of the traction wire 200 is naturally placed on the liner 2. The clamping device 12 ensures that the traction wire 200 placed within it is straight, thus aligning the portion of the traction wire 200 within the clamping device 12 with the bushing 2. At this point, glue can be applied to the traction wire 200 within the clamping device 12 to bond it to the bushing 2, completing the bonding of the end of the traction wire 200 to the end of the bushing 2. Subsequently, the clamping device 12 can be slid to retract the remaining portion of the traction wire 200 within it, and glue can be applied again to the traction wire 200 within the clamping device 12, and so on, until the entire traction wire 200 is bonded to the bushing 2.

[0033] It is understood that the clamping device 12 functions to straighten the traction wire 200, ensuring that the traction wire 200 is straight within the clamping device 12. Simultaneously, the clamping device 12 moves along the axial direction of the liner 2; that is, after the clamping device 12 passes over the entire traction wire 200, the entire traction wire 200 will be parallel to the liner 2, thus ensuring that the traction wire 200 can be straightened and bonded to the liner 2. This prevents the traction wire 200 from being improperly straightened within the sheath, avoiding a twisted state during bending, which would affect the bending function and aesthetics of the sheath. Furthermore, by bonding the traction wire 200 to the liner 2 in this manner, there is no need to visually inspect whether the traction wire 200 is straight; the clamping device 12 guarantees the straightness of the traction wire 200, thereby improving product yield, increasing wire bonding efficiency, and reducing time and labor costs.

[0034] Further, please refer to Figures 2-4 The clamping device 12 includes a first clamping member 121 and a second clamping member 122. The first clamping member 121 and the second clamping member 122 are spaced apart, thus a gap 123 exists between them. This gap 123 is used to accommodate the traction wire 200, allowing the clamping device 12 to straighten the traction wire 200. In a specific embodiment of the invention, the size of the gap 123 is similar to the size of the traction wire 200, meaning there is a small gap between the traction wire 200 and both the first and second clamping members 121 and 122. This gap ensures that the clamping device 12 can move relative to the traction wire 200. The traction wire 200 cannot be bent or deformed within the narrow gap 123, thus keeping the traction wire 200 within the gap 123 in a straight state. Furthermore, the gap 123 of the clamping device 12 has an elongated structure, and the gap 123 is located directly above the liner 2. The gap 123 is parallel to the liner 2, so the traction wire 200 clamped in the gap 123 will be parallel to the liner 2.

[0035] Furthermore, please refer to Figure 1 , Figure 3 and Figure 4The bonding table 11 has sliding grooves 112 on two adjacent sides of the side with the receiving groove 111. The clamping device 12 includes a first sliding member 124 and a second sliding member 125, which respectively cooperate with the sliding grooves 112 on both sides of the bonding table 11. The first sliding member 124 and the second sliding member 125 can slide within the sliding grooves 112. The first clamping member 121 cooperates with the first sliding member 124, and the second clamping member 122 cooperates with the second sliding member 125. In a specific embodiment of the present invention, the first clamping member 121 and the second clamping member 122 have an "L"-shaped structure. One side of the first clamping member 121 is parallel to the side of the bonding table 11 with the sliding groove 112, and the other side is parallel to the side of the bonding table 11 with the receiving groove 111. One side of the second clamping member 122 is parallel to the side of the wire-adhesive table 11 where the sliding groove 112 is provided, and the other side is parallel to the side of the wire-adhesive table 11 where the receiving groove 111 is provided. The first clamping member 121 and the second clamping member 122 can be fixed to the first sliding member 124 and the second sliding member 125 respectively by nuts. The movement of the first sliding member 124 will drive the first clamping member 121 to move, and the movement of the second sliding member 125 will drive the second clamping member 122 to move. Moreover, the first sliding member 124 and the second sliding member 125 move synchronously, so the first clamping member 121 and the second clamping member 122 move synchronously.

[0036] In other specific embodiments of the present invention, the first clamping member 121 may be interchanged with the second clamping member 122, and the first sliding member 124 may also be interchanged with the second sliding member 125.

[0037] Please see Figures 3-5To ensure synchronous movement of the first clamping member 121 and the second clamping member 122, in a specific embodiment of the present invention, the sliding groove 112 is a through-groove structure, that is, the sliding groove 112 is a through-groove structure that passes through two adjacent sides of the side of the wire-adhesive table 11 where the receiving groove 111 is provided, i.e., the sliding groove 112 passes through the two sides of the wire-adhesive table 11 where the sliding groove 112 is provided. The clamping device 12 also includes a mating member 126, which passes through the sliding groove 112. The mating member 126 includes a first mating part 1261, a second mating part 1262, and a limiting part 1263. The first mating part 1261 and the second mating part 1262 are respectively provided at both ends of the mating member 126, and the limiting part 1263 is provided between the first mating part 1261 and the second mating part 1262. The first sliding member 124 engages with the first mating part 1261, and the side of the first sliding member 124 near the slide groove 112 abuts against the limiting part 1263. The second sliding member 125 engages with the second mating part 1262, and the side of the second sliding member 125 near the slide groove 112 abuts against the limiting part 1263. Specifically, both the first mating part 1261 and the second mating part 1262 are threaded structures. The first sliding member 124 is threadedly connected to the first mating part 1261, and the second sliding member 125 is threadedly connected to the second mating part 1262. The first sliding member 124 and the second sliding member 125 are connected through the mating part 126. Therefore, when the first sliding member 124 moves, it will drive the mating part 126 and the second sliding member 125 to move together, thereby causing the first clamping member 121 and the second clamping member 122 to move together, thus realizing the overall coordinated movement of the clamping device 12.

[0038] In other specific embodiments of the present invention, the positions of the first mating part 1261 and the second mating part 1262 can be interchanged.

[0039] Further, please refer to Figures 2-5The first mating part 1261 and the second mating part 1262 have opposite thread rotation directions. The clamping device 12 also includes a rotating member 127 and a limiting member 128. The rotating member 127 is disposed on the first mating part 1261 or the second mating part 1262, and the limiting member 128 is disposed on the second mating part 1262 or the first mating part 1261. When the rotating member 127 is rotated, it drives the first mating part 1261 and the second mating part 1262 to rotate. Since the first mating part 1261 and the second mating part 1262 have opposite thread rotation directions, when the first mating part 1261 and the second mating part 1262 rotate, they will drive the first sliding member 124 and the second sliding member 125 to move closer to each other or further away from each other. It is understood that, to ensure the traction wire 200 can be securely housed within the gap 123, the rotating member 127 can be rotated to bring the first sliding member 124 and the second sliding member 125 closer together, thereby bringing the first clamping member 121 and the second clamping member 122 closer together, thus reducing the gap 123. The first clamping member 121 and the second clamping member 122 will then clamp the traction wire 200 located within the gap 123, ensuring the traction wire 200 is securely housed within the gap 123. This prevents the traction wire 200 from shaking or moving during bonding, which would prevent it from being bonded straight to the liner 2. Simultaneously, the clamped traction wire 200 will also be straighter. When the bonding is complete and the clamping device 12 needs to be moved, the rotating member 127 can be rotated to move the first sliding member 124 and the second sliding member 125 away from each other, increasing the gap 123. The first clamping member 121 and the second clamping member 122 will no longer clamp the traction wire 200, allowing the clamping device 12 to be moved. Simultaneously, the rotating member 127 and the limiting member 128 prevent the first sliding member 124 and the second sliding member 125 from slipping off the mating member 126, ensuring that the first sliding member 124 and the second sliding member 125 are always connected to the mating member 126.

[0040] Simultaneously, by setting the length of the limiting part 1263, after the first sliding member 124 and the second sliding member 125 move towards each other a certain distance, the first sliding member 124 and the second sliding member 125 will abut against the limiting part 1263, thereby restricting the first sliding member 124 and the second sliding member 125 from continuing to move towards each other. This avoids the gap 123 becoming too small due to the first sliding member 124 and the second sliding member 125 moving too far towards each other, thus preventing the clamping force of the first clamping member 121 and the second clamping member 122 on the traction wire 200 from being too large and causing damage to the traction wire. Furthermore, to prevent the mating member 126 from shifting along its axial direction, thereby causing the entire clamping device 12 to shake on the wire bonding table 11. The inner wall surface of the groove 112 away from the liner 2 protrudes in the direction of the liner 2 to form a protrusion structure 1121, and the limiting part 1263 is recessed inward to form a groove structure 1264. The protrusion structure 1121 and the groove structure 1264 cooperate to restrict the mating part 126 from shifting along its axial direction.

[0041] Please see Figure 4 and Figure 6 Because the traction wire 200 is small, it is difficult for the user to align it with the adhesive during the application of glue. Therefore, in this specific embodiment of the invention, the side of the first clamping member 121 closest to the second clamping member 122 is inclined towards the liner 2 to form a first ramp structure 1211, and the side of the second clamping member 122 closest to the first clamping member 121 is inclined towards the liner 2 to form a second ramp structure 1221. That is, the first ramp structure 1211 and the second ramp structure 1221 together form a flared structure. The first ramp structure 1211 and the second ramp structure 1221 together serve as guides. When applying glue, the user only needs to drip the glue onto the first ramp structure 1211 or the second ramp structure 1221, and the glue will flow into the gap 123 along the first ramp structure 1211 or the second ramp structure 1221, thus facilitating the application of glue. At the same time, since the sheath tube has various sizes, the liner 2 also has various sizes. On the wire bonding table 11, the side with the receiving groove 111 is inclined to the inner wall of the receiving groove 111 to form a third slope structure 113. The third slope structure 113 enables the receiving groove 111 to stably accommodate the liner rods 2 of different sizes.

[0042] Further, please refer to Figure 1 and Figure 7The wire-adhesive device 1 further includes an adapter 13, which includes an adapter 131 and a fixing member 132. The fixing member 132 is fixed to the end of the wire-adhesive table 11. An adapter groove 1321 is provided on the side of the fixing member 132 near the liner 2, and the adapter 131 is disposed within the adapter groove 1321, allowing it to move within the groove. An adapter hole 1311 is provided on the side of the adapter 131 near the liner 2, and one end of the liner 2 is housed within the adapter hole 1311. It can be understood that the adapter 131 is used to fix the liner 2. When the end of the liner 2 is housed within the adapter hole 1311, the liner 2 is fixed to the adapter 131, ensuring the liner 2 is securely placed on the wire-adhesive table 11. In a specific embodiment of the present invention, the adapter 131 is provided with a plurality of adapter holes 1311, each with a different size, to connect with the liner rods 2 of different sizes. Each adapter hole 1311 is on a straight line, and this straight line is parallel to the adapter groove 1321. The vertical height H of each adapter hole 1311 on the adapter 131 is different. After the liner rod 2 of one specification is glued with wire, if a liner rod 2 of a different specification needs to be replaced, the adapter 131 can be slid so that the adapter hole 131 on the adapter 131 corresponding to the specification of the liner rod 2 is aligned with the replaced liner rod 2 on the same straight line. Then, the end of the liner rod 2 is connected to the adapter hole 1311, thereby fixing the replaced liner rod 2 on the adapter 131. By setting the adapter 131 and the fixing member 132, the liner 2 can be fixed relative to the wire bonding table 11, thereby keeping the liner 2 stable during the wire bonding process. The adapter hole 1311 allows the adapter 131 to be adapted to various sizes of the liner 2, thereby improving the applicability of the wire bonding device 1.

[0043] Furthermore, please refer to Figures 7-9 On the end of the liner 2 that mates with the adapter hole 1311, the shape of the end of the liner 2 can be adapted to the number of traction wires 200 that need to be bonded to the liner 2, and the shape of the adapter hole 1311 corresponds to the shape of the end of the liner 2. For example, if four traction wires 200 need to be bonded to the liner 2 to achieve four-way bending of the sheath, the end of the liner 2 can be set as a rectangular structure, such as... Figure 9As shown, the adapter hole 1311 is correspondingly rectangular in shape. After one of the traction wires 200 is bonded to the bushing 2, the end of the bushing 2 is pulled out from the adapter hole 1311, then the bushing 2 is rotated 90 degrees, and then the end of the bushing 2 is engaged with the adapter hole 1311. At this point, the bushing 2 has completed a 90-degree rotation and is fixed to the adapter 131. Then, the second traction wire 200 can be bonded, and so on, until the last traction wire 200 is bonded to the bushing 2. This method allows multiple traction wires 200 to be accurately bonded to the bushing 2 at the required angle, improving the accuracy and convenience of the bonding. Simultaneously, a traction wire receiving groove 1111 is adaptively provided within the receiving groove 111, which is used to receive the traction wires 200 located within it. After attaching one of the traction wires 200 to the liner 2, the liner 2 needs to be rotated by a certain angle. After rotation, the traction wire 200 attached to the liner 2 will enter the receiving groove 111. Therefore, a traction wire receiving groove 1111 is provided in the receiving groove 111 to receive the traction wire 200 and avoid interference between the traction wire 200 and the receiving groove 111. The number and position of the traction wire receiving grooves 1111 in the receiving groove 111 can be adaptively set according to the number of traction wires 200 attached to the liner 2 as needed.

[0044] Please see Figure 7 and Figure 10 The adapter 13 further includes a first locking member 133 and a second locking member 134. In a specific embodiment of the present invention, both the first locking member 133 and the second locking member 134 are screws. The first locking member 133 is disposed on the side of the fixing member 132 away from the adapter 131. The first locking member 133 passes through the fixing member 132 and is threadedly engaged with the adapter 131, thereby fixing the adapter 131 to the fixing member 132. The second locking member 134 is disposed on the side of the wire-adhesive table 11 away from the fixing member 132. The second locking member 134 passes through the wire-adhesive table 11 and is threadedly engaged with the fixing member 132, thereby fixing the fixing member 132 to the wire-adhesive table 11. It is understood that when the adapter 131 needs to slide relative to the fixing member 132, the first locking member 133 can be rotated to loosen the first locking member 133 from the adapter 131. At this time, the adapter 131 can move relative to the fixing member 132. After moving to the target position, the first locking member 133 can be rotated again to lock the adapter 131 onto the fixing member 132.

[0045] Compared with existing technologies, the wire bonding system of the present invention has the following advantages: the wire bonding system ensures that the traction wire is bonded straight to the liner. This prevents the traction wire from being improperly positioned within the sheath, avoiding a twisted state during bending and affecting the bending function and aesthetics of the sheath. Furthermore, by bonding the traction wire to the liner in this manner, there is no need to visually inspect the straightness of the traction wire; the clamping device ensures the straightness of the traction wire, thereby improving product yield, increasing wire bonding efficiency, and reducing time and labor costs.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included within the protection scope of the present invention.
