Description

Technical Field

[0001] This application relates to the field of medical device processing technology, and more specifically, to a fiber loading device. Background Technology

[0002] Coils are a special medical device used to fill the cavity of intracranial aneurysms or the site of vascular embolization. The principle of coil embolization for treating intracranial aneurysms is: by inserting coils to close the cavity of intracranial aneurysms, the intracranial aneurysms are isolated from blood circulation or the blood flow within the aneurysm is slowed down, thereby accelerating the formation of thrombi within the aneurysm. As the coils become completely endothelialized within the aneurysm, the intracranial aneurysm is eventually completely healed.

[0003] Currently, the method for preparing embolization spring coils is to first wind platinum-tungsten alloy wire into a primary spiral, then wind and heat-treat the primary spiral to form a secondary shape spring coil; then fix the secondary shape spring coil on a specific tooling or equipment, automatically or manually wind fibers onto the secondary shape spring coil, and then cut the fibers to form a spring coil with fibers.

[0004] Existing spring coil winding fixtures for fixing secondary shaped spring coils and winding fiber fibers typically have positioning grooves on the fixture body to fix the spring coils, and several winding grooves on the fixture body to position the wound fiber fibers. However, using this type of spring coil winding fixture results in poor fixation of the wound fiber fibers on the spring coils, and the fiber fibers are prone to detaching from the spring coils. Summary of the Invention

[0005] The purpose of this application is to provide a fiber loading device that can improve the winding and fixing effect of the fiber on the spring coil and reduce the fiber detachment phenomenon.

[0006] In a first aspect, embodiments of this application provide a fiber loading device, which includes a base, a winding body is disposed on the base, and a plurality of winding grids are fixedly disposed on the winding body and arranged at intervals along a first direction. The winding grids extend along a second direction, and there is a gap between two adjacent winding grids along the first direction, wherein the second direction is perpendicular to the first direction. The winding grid is provided with a limiting channel extending in the first direction at the top away from the winding body along the second direction. Multiple limiting channels are connected in sequence to form a spring channel for accommodating the spring coil body. The fiber hairs are delivered through the gap so that the fiber hairs can be wound around the spring coil body.

[0007] In the above process, on the one hand, the fiber loading device provides a spring channel, which can effectively accommodate and limit the spring ring body, reducing its displacement during processing; on the other hand, the part of the spring ring that needs to be wrapped with fibers can be exposed in the gap between adjacent winding grids, which facilitates the all-round winding and fixing of fibers on the spring ring, improves the winding and fixing effect of fibers on the spring ring, and reduces the phenomenon of fibers detaching.

Detailed Implementation

[0011] In the description of this application, it should be noted that the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0012] Currently, the coil systems used clinically mainly consist of three parts: embolization coils, delivery system, and connection points. Embolization coils are generally composed of primary platinum-tungsten alloy wire, anti-unwinding wire, and PET fiber hairs. The preparation method of embolization coils is usually as follows: First, the platinum-tungsten alloy wire is wound onto a cylindrical mandrel to form a primary helix; then, the primary helix is ​​wound onto another mandrel, and after heat treatment, a secondary-shaped coil is formed. This coil is classified into two types based on its secondary morphology: 2D helical coils and 3D composite coils. The helical coil is formed by the primary helix wound onto a cylindrical mandrel, while the composite coil is formed by the primary helix wound onto a multi-dimensional mandrel. Next, the secondary-shaped coil is fixed to a specific fixture or equipment, and fiber hairs are automatically or manually wound onto the secondary-shaped coil and then cut to form a coil with fiber hairs. The fiber hairs in the coil increase the friction and adhesion between the coil and the aneurysm wall, making the coil more stable within the aneurysm and less prone to displacement or dislodgement, thereby effectively reducing the aneurysm recanalization rate. At the same time, fibrous tissue can also promote the formation and organization of thrombi, accelerate the healing process of aneurysms, and improve the complete embolization rate.

[0013] Existing spring coil winding fixtures for fixing secondary shaped spring coils and winding fiber fibers typically have positioning grooves on the main body of the fixture to fix the spring coil, and several winding grooves on the main body to position the wound fiber fibers. However, with this type of spring coil winding fixture, the fiber fibers are only wound and fixed to the portion of the spring coil exposed in the positioning grooves, resulting in poor fixation and a tendency for the fiber fibers to detach from the spring coil.

[0014] Therefore, it is necessary to design a fiber loading device to solve the above-mentioned technical problems.

[0015] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0016] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a fiber loading device, which includes a base 1. The base 1 is provided with a fiber winding component 2 extending along a first direction X. The fiber winding component 2 is used to wind the fiber onto the spring coil body. The fiber winding component 2 includes a winding body 3 and a plurality of winding grids 4 disposed on the winding body 3. Specifically, the base 1 is provided with a winding body 3 extending along the first direction X. A plurality of winding grids 4 are fixedly disposed on the winding body 3 and spaced apart along the first direction X. The winding grids 4 extend along a second direction Z. There is a gap 21 between two adjacent winding grids 4 along the first direction X. The second direction Z is perpendicular to the first direction X. A limiting channel 5 extending along the first direction X is provided at the top of the winding grid 4 away from the winding body 3 along the second direction Z. The plurality of limiting channels 5 are connected in sequence to form a spring channel 500 for accommodating the spring coil body. The gap 21 needs to extend to the circumference of the spring channel 500 to realize the circumferential winding of the fiber onto the spring coil. The fiber can be wound onto the spring coil body by shuttling through the gap 21.

[0017] In this application, the first direction X, the second direction Z, and the third direction Y refer to three mutually perpendicular directions in three-dimensional space. (Combined with...) Figure 1 From the perspective of the three-dimensional spatial coordinate system corresponding to the fiber loading device after conventional settings, the first direction X refers to the x-axis (the horizontal axis in the diagram, representing the left-right direction) in the three-dimensional spatial coordinate system, the second direction Z refers to the z-axis (the vertical axis in the diagram, representing the up-down direction) in the three-dimensional spatial coordinate system, and the third direction Y refers to the y-axis (the vertical axis in the diagram, representing the front-back direction) in the three-dimensional spatial coordinate system. Accordingly, the two orientations of "top" and "bottom" in this application are viewed along the second direction Z (the z-axis in the three-dimensional spatial coordinate system). The position relatively closer to the base 1 is the "bottom", and the position relatively farther away from the base 1 is the "top".

[0018] This fiber loading device, by setting a winding body 3 on a base 1 and multiple winding grids 4 arranged at intervals along a first direction X, connects the top of the winding grids 4 to form a spring channel 500, which can effectively accommodate and limit the spring coil body, reducing its displacement during processing. The gap 21 between adjacent winding grids 4 provides a stable path for the shuttle delivery of the fiber, ensuring that the fiber can be accurately wound on the spring coil body, achieving all-round winding and fixing of the fiber on the spring coil, improving the winding and fixing effect of the fiber on the spring coil, and reducing the phenomenon of fiber detachment. Moreover, the part of the spring coil body that needs to be wound can be exposed in the gap between adjacent winding grids, and the fiber can be directly wound onto the spring coil, avoiding friction caused by the fiber winding on the tooling body and reducing the risk of fiber damage.

[0019] In some embodiments of this application, such as Figure 4 and Figure 6 As shown, the limiting channel 5 includes a through channel 50 that penetrates the winding grid 4; Along the third direction Y, the winding grid 4 includes a movable first winding grid 41 and a fixed second winding grid 42. The first winding grid 41 and the second winding grid 42 can be interlocked to form a through channel 50, which can accommodate the spring coil body of the fiber hair to be wound. The third direction Y is perpendicular to the first direction X and the second direction Z, respectively. Multiple through channels 50 form a spring channel 500, which can circumferentially wrap the spring coil body.

[0020] It should be noted that in this embodiment, the limiting channel 5 is in the form of a through channel 50, which is used to accommodate the spring coil body, so that the through channel 50 completely encloses the spring coil body 360° circumferentially, that is, the spring coil body is completely enclosed in the through channel 50 and is not exposed. In other embodiments, the limiting channel 5 can also be designed as a groove channel, that is, the spring coil body is not completely enclosed in the groove channel, and part of the spring coil body is exposed. The opening width of the groove channel is matched with the outer diameter of the spring coil body to achieve fixation of the spring coil body.

[0021] In this embodiment, the winding grid 4 is designed as a split type, with the two parts interlocking to form a through channel 50, and can move relative to each other to open the through channel 50 for placing the spring coil. In other embodiments, the winding grid 4 can also be designed as a single piece, with limiting channels 5 provided on the top of at least a portion of the winding grids 4.

[0022] In the embodiments of this application, such as Figure 4 and Figure 5As shown, by dividing the winding grid 4 into a movable first winding grid 41 and a fixed second winding grid 42, the two can be fitted together to form a through channel 50. The spring channel 500, composed of multiple through channels 50, can circumferentially wrap around the spring coil body, greatly improving the fixing stability and enhancing the stability during winding and cutting of fiber fibers. At the same time, the first winding grid 41 is movable, allowing the spring channel 500 to be easily opened and closed, facilitating the handling of the spring coil body and simplifying the processing procedure.

[0023] Please combine Figure 5 and Figure 6 As shown, in some embodiments of this application, the winding body 3 includes a first winding body 31 and a second winding body 32 arranged side by side along a third direction Y. A plurality of first winding grids 41 are fixedly disposed on the first winding body 31 and arranged at intervals along a first direction X. A plurality of second winding grids 42 are fixedly disposed on the second winding body 32 and arranged at intervals along the first direction X. The first winding body 31 can move relative to the second winding body 32 along a second direction Z to drive all the first winding grids 41 to move relative to the second winding grids 42 along the second direction Z.

[0024] It should be noted that, in this embodiment, the first winding body 31 and the second winding body 32 can be columnar or plate-like structures extending along the first direction X. Multiple first winding grids 41 fixed to the first winding body 31 can move simultaneously with the first winding body 31. The first winding body 31 and the second winding body 32 are arranged side-by-side along the third direction Y. Correspondingly, the first winding grids 41 and the second winding grids 42 correspond one-to-one and are also arranged side-by-side along the third direction Y. In other embodiments, the first winding body 31 and the second winding body 32 can also be stacked along the second direction Z (vertical direction). Correspondingly, the first winding grids 41 and the second winding grids 42 correspond one-to-one and are stacked. They can also interlock to form a through channel 50.

[0025] In this embodiment, the winding body 3 is designed as a first winding body 31 and a second winding body 32 arranged side by side along the third direction Y. The first winding grid 41 and the second winding grid 42 are fixed to each other respectively. By driving the first winding body 31 to move as a whole, all the first winding grids 41 can be driven to move synchronously relative to the second winding grid 42, ensuring that the opening and closing actions of all through channels 50 are consistent and avoiding spring coil positioning deviations caused by asynchronous movement of individual grids. This synchronous driving method is simple to operate, significantly improves processing efficiency, and ensures uniform fixing force at each part of the spring coil, which is beneficial to the uniformity of fiber winding and further optimizes the product processing effect.

[0026] Please combine Figure 5 and Figure 6As shown, in some embodiments of this application, the first winding grid 41 includes a bottom grid 411 extending along the second direction Z and a top grid 412 extending along the third direction Y from the top of the bottom grid 411 away from the first winding body 31 in the second direction Z; the top surface of the second winding grid 42 is provided with a first groove 421 extending along the first direction X, and the bottom surface of the top grid 412 abuts against the top surface of the corresponding second winding grid 42, so that the bottom surface of the top grid 412 surrounds the first groove 421 to form a through channel 50. Optionally, the cross-sectional shape of the first groove 421 includes an arc shape, which can match and accommodate the spring coil body structure. In other alternative embodiments, the bottom surface of the top grille 412 is provided with a second groove, which is arc-shaped. The through channel 50 formed by the first groove 421 and the second groove is a circular channel, so that the spring coil body is tightly wrapped, while avoiding damage or compression to the spring coil body.

[0027] In this embodiment, the first winding grid 41 includes a bottom grid 411 and a top grid 412 connected together. The bottom grid 411 extends along the second direction Z, and the top grid 412 extends from the top of the bottom grid 411 along the third direction Y toward the second winding grid 42. The bottom grid 411 and the second winding grid 42 have the same structure, and the top grid 412 covers and is disposed above the bottom grid 411 and the second winding grid 42, thus forming a through channel 50. In this embodiment, the fiber winding component 2 is designed as a split structure arranged side-by-side along the third direction Y. The top of the first winding grid 41 covers the top of the second winding grid 42, and the first winding grid 41 can move relative to the second winding grid 42 along the second direction Z. This design has a compact overall structure and a small footprint; it also facilitates the placement of the spring coil body and provides good fixation; the structure only has a closed gap below the limiting channel 5, and the upper part of the limiting channel 5 is unobstructed, facilitating the winding action of the fiber fibers. In other embodiments, the first winding grid 41 and the second winding grid 42 may also be arranged side by side along the third direction Y, and the top grid 412 is eliminated. The through channel 50 is formed by the adjacent surfaces of the first winding grid 41 and the second winding grid 42 being fitted together. Accordingly, the first winding grid 41 (first winding body 31) can be moved relative to the second winding grid 42 (second winding body 32) along the third direction Y to open the through channel 50.

[0028] In this embodiment, the top surface of the second winding grid 42 is provided with a first groove 421 extending along the first direction X, and the top grid 412 surrounds the first groove 421 to form a through channel. In other embodiments, a second groove extending along the first direction X can also be provided on the bottom surface of the top grid 412, and the second groove and the first groove 421 are joined together to form a through channel; or a second groove extending along the first direction X can be provided only on the bottom surface of the top grid 412, and the second winding grid 42 surrounds the second groove to form a through channel.

[0029] In this embodiment, the through channel 50 is formed by the bottom grille 411, the top grille 412, and the first groove 421 of the second winding grille 42, or by adding a second groove to form the enclosure. This allows the channel size to be adjusted according to the specifications of the spring coil, improving the adaptability of the device. The top surfaces of the top grille 412 and the second winding grille 42 abut against each other, ensuring the sealing and wrapping properties of the through channel 50 and effectively limiting the slight displacement of the spring coil. This structural design ensures that the through channel 50 fits tightly against the spring coil body, guaranteeing both stability and protection for the spring coil during winding, reducing the risk of compression deformation. It also facilitates manufacturing and reduces production costs.

[0030] Please combine Figure 4 and Figure 7 As shown, in some embodiments of this application, the first side of the first winding grid 41 adjacent to the top surface of the top grid 412 is provided with a fiber winding column 7 arranged along the third direction Y; the top surface of the top grid 412 is provided with a fiber orientation groove 6 extending along the fourth direction, the fiber orientation groove 6 includes a starting end 61 near the fiber winding column 7 and a terminating end 62 away from the fiber winding column 7, the starting end 61 is located at the middle position of the top grid 412 extending along the first direction X; optionally, the included angle θ between the fourth direction and the third direction Y satisfies: 0≤θ≤25°.

[0031] In the embodiments of this application, such as Figure 1 and Figure 5 As shown, fiber winding posts 7 are provided on the first side of the first winding grid 41, providing positioning fulcrums for the winding of the fiber fibers and ensuring stable tension during winding. The fiber orientation groove 6 of the top grid 412 can guide the fiber fibers to wind along a preset fourth direction, making the fiber fibers evenly distributed and avoiding messy winding. The angle θ between the fourth direction and the third direction Y is set between 0-25°, so that the fiber fibers wind along the fiber orientation groove 6 and in the direction of the inclined coil of the spring coil body, avoiding friction and compression between the fiber fibers and the spring coil, which would cause damage to the fiber fibers and deformation of the spring coil.

[0032] In some embodiments of this application, such as Figure 7As shown, the top surface of the top grid 412 is provided with a fiber hair cutting groove 8 extending along the first direction X. The fiber hair cutting groove 8 is located on the side of the fiber hair orientation groove 6 near the fiber hair winding column 7. Optionally, the fiber hair cutting groove 8 abuts against the starting end 61.

[0033] In this embodiment, the fiber tuft cutting groove 8 provided on the top surface of the top grid 412 provides precise guidance for cutting the wound fibers, ensuring consistent cutting length and a smooth cut, thus improving product consistency and aesthetics. The fiber tuft cutting groove 8 abuts against the starting end 61 of the fiber tuft orientation groove 6, ensuring that the cutting position precisely corresponds to the winding start position. Since the starting end 61 of the fiber tuft orientation groove 6 is located at the middle position of the top grid 412 extending along the first direction X, the fiber tuft cutting groove 8 abuts against the starting end 61, ensuring that the length of the cut fibers is equal after cutting along the fiber tuft cutting groove 8. This structure simplifies the cutting operation, reduces cutting difficulty, improves processing efficiency, and simultaneously ensures the structural integrity and performance of the product.

[0034] In some embodiments of this application, such as Figure 4 As shown, along the first direction X, the gap 21 includes a winding gap 211 located between two adjacent limiting channels 5, and a shuttle gap 212 close to the winding body 3. The width of the winding gap 211 along the first direction X is smaller than the width of the shuttle gap 212 along the first direction X. Optionally, there is a guide gap 213 with a gradually decreasing width between the shuttle gap 212 and the winding gap 211.

[0035] In this embodiment, the gap 21 is divided into a winding gap 211 and a shuttle gap 212, with the width of the winding gap 211 being smaller than that of the shuttle gap 212. This ensures smooth delivery of the fiber fibers within the shuttle gap 212 while allowing for tight winding of the fiber fibers at the winding gap 211, thus improving the fixing effect. The guide gap 213 enables a smooth transition of the fiber fibers from the shuttle gap 212 to the winding gap 211, allowing the fiber fibers shuttling through the shuttle gap 212 to be smoothly positioned along the guide wire onto the spring coil body corresponding to the winding gap 211, preventing the fiber fibers from getting stuck or damaged at the gap transition.

[0036] In some embodiments of this application, along the first direction X, a plurality of winding gaps 211 include a first winding gap near the proximal end of the spring coil body and a second winding gap away from the proximal end of the spring coil body. The width d1 of the first winding gap along the first direction X and the width d2 of the second winding gap along the first direction X satisfy: d1≤d2.

[0037] In other optional embodiments of this application, the winding gap 211 among the plurality of gaps 21 is divided into a first winding gap and a second winding gap with different widths along the first direction X. The fiber density can be adjusted according to the winding requirements of different parts of the spring coil, so that the overall performance of the spring coil is better and further meets the customized needs of clinical use. For example, the width of the first winding gap near the proximal end of the spring coil body corresponds to 1 coil line, and the width of the second winding gap away from the proximal end of the spring coil body corresponds to 2-3 coil lines.

[0038] Please see Figure 1 , Figure 3 and Figure 5 In some embodiments of this application, the first winding body 31 is driven by a lifting mechanism 9. The lifting mechanism 9 includes a rotating handle 91 and a cam mechanism 92 connected to the rotating handle 91. The cam mechanism 92 abuts against the bottom of the first winding body 31 facing the base 1. By rotating the rotating handle 91, the cam mechanism 92 is driven to rotate, thereby driving the first winding body 31 to reciprocate along the second direction Z. Optionally, the cam mechanism 92 includes a mandrel, a constant diameter section and a variable diameter section with the mandrel as the rotation axis. It should be noted that the radius is equal in the constant diameter section, and the radius gradually increases in the variable diameter section. The minimum radius in the variable diameter section connects to the constant diameter section. When the cam mechanism 92 rotates, the distance between the surface of the cam mechanism 92 and the mandrel gradually increases from the constant diameter section to the variable diameter section, thereby adjusting the height of the contact cam mechanism 92. When the rotating handle 91 rotates the cam mechanism 92 so that the equal diameter part abuts against the first winding body 31, the first winding grid 41 and the second winding grid 42 fit together to form a through channel 50; when the rotating handle 91 rotates the cam mechanism 92 so that the variable diameter part abuts against the first winding body 31, the first winding grid 41 moves along the second direction Z toward the side away from the base 1, thereby exposing the through channel 50.

[0039] In this embodiment, the lifting mechanism 9 drives the movement of the first winding grid 41 to open the limiting channel 5. The lifting mechanism 9 is driven in a semi-automatic manner. The first winding body 31 is equipped with the lifting mechanism 9, which includes a rotating handle 91 and a cam mechanism 92 connected to the rotating handle 91. By rotating the rotating handle 91, the cam mechanism 92 is rotated, thereby raising or lowering the first winding grid 41 along the second direction Z. In other embodiments, manual or fully automatic driving methods can also be used.

[0040] In this embodiment, the lifting mechanism 9, composed of a rotary handle 91 and a cam mechanism 92, drives the first winding body 31 to move. Operation is simple and quick; simply rotating the rotary handle 91 is sufficient to raise and lower the first winding grid 41, reducing operational difficulty. The equal-diameter and variable-diameter sections of the cam mechanism 92 precisely control the travel of the first winding body 31. When the equal-diameter section abuts, the first winding grid 41 and the second winding grid 42 precisely engage to form a through channel 50, ensuring a secure connection. When the variable-diameter section abuts, the through channel 50 is stably exposed, facilitating the removal and placement of the spring coil. This lifting mechanism 9 is structurally stable and precisely controlled, improving the ease of operation and manufacturing reliability of the device, and reducing the impact of human error.

[0041] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the base 1 is provided with a first support structure 11 and a second support structure 12 spaced at a preset distance along a first direction X. A first clamp is provided on the first support structure 11, and a second clamp is provided on the second support structure 12. The first clamp and the second clamp detachably fix the two ends of the spring coil body. In this embodiment, the first support structure 11 and the second support structure 12 are spaced at a preset distance, and the first clamp and the second clamp include a fixing clamp 13, which can fix the two ends of the spring coil body.

[0042] In this embodiment, by providing a first support structure 11, a second support structure 12, and corresponding clamps on the base 1, both ends of the spring coil body can be detachably fixed. This, in conjunction with the spring channel 500, achieves omnidirectional positioning of the spring coil, effectively limiting its axial displacement. The fixed-end design ensures the stability of the spring coil's posture during processing, guaranteeing uniform fiber winding and preventing uneven fiber winding density caused by axial displacement. The detachable design of the clamps facilitates the installation and removal of the spring coil ends and is adaptable to spring coils with different end structures, improving the device's versatility.

[0043] In some embodiments of this application, at least one of the first support structure 11 and the second support structure 12 can be moved along the first direction X to adjust the distance between the first clamp and the second clamp; optionally, the first support structure 11 and / or the second support structure 12 includes a fixed support structure 121 fixed on the base 1 and a movable support structure 122 located on the fixed support structure 121. The fixed support structure 121 is provided with a rotating knob 123, and the movable support structure 122 can be moved back and forth relative to the fixed support structure 121 along the first direction X by rotating the rotating knob 123.

[0044] In this embodiment, the second support structure 12 is movable along the first direction X. The second support structure 12 includes a fixed support structure 121 fixed on the base 1 and a movable support structure 122 located on the fixed support structure 121. The fixed support structure 121 is provided with a rotation knob 123. By rotating the rotation knob 123, the movable support structure 122 can be moved in the first direction X.

[0045] In this embodiment, the first support structure 11 and the second support structure 12 are designed to move along the first direction X. By rotating the knob 123 to adjust the clamp spacing, it can adapt to the processing requirements of spring coils of different lengths, thus improving the versatility of the device. Before loading the fiber fibers, the pitch of the spring coil body can be increased by adjusting the spacing, making it easier for the fiber fibers to embed into the gap between the coil wires. After loading, the spacing is adjusted back to restore the pitch of the spring coil body, ensuring that the fiber fibers are firmly fixed and effectively reducing the risk of falling off.

[0046] The fiber loading device in this embodiment loads fibers as follows: The first winding body 31 is driven by the lifting mechanism 9. The first winding grid 41 is raised and moved to expose the limiting channel 5. The spring ring body of the fiber hair to be wound is placed in the limiting channel 5 along the first direction X. Then the first winding grid 41 is lowered and moved. The spring ring body of the fiber hair to be wound is wrapped in all directions by the top grid 412, the bottom grid 411 and the second winding grid 42, which greatly improves the stability and fixation of the spring ring body. The two ends of the spring coil body are fixed on the fixing clamps 13 of the first support structure 11 and the second support structure 12 to achieve all-round fixation of the spring coil body. When winding the fiber, the fiber is delivered through the shuttle gap 212 and wound at the position where the spring coil body is located at the winding gap 211, so that the fiber can be wound 360°. After winding is completed, the blade moves along the fiber cutting groove 8 to cut the fiber, and then drives the first winding grid 41 to move upward, loosening the fixing of the fixing clamp 13, and obtaining the spring coil loaded with fiber.

[0047] In summary, the fiber loading device of this application embodiment can improve the winding and fixing effect of the fiber on the spring coil and reduce the fiber detachment phenomenon.
