[0002] High-toughness polyetheretherketone medical catheters need to be rolled up during the production process. In the related technology, the speed of the conveying catheter and the rolling catheter is uniform. During the rolling process, the tensioning device keeps the catheter tensioned to ensure the rolling effect. However, as the number of rolled layers increases, the length of each layer of catheter increases, and the position of the tensioning device is fixed, resulting in an increase in the pulling force on the catheter that has not been rolled up, which will cause the catheter to deform and affect the quality of the catheter.

[0003] Therefore, in order to solve the technical problem that the catheter is deformed and damaged due to the increased pulling force on the catheter during the winding process, it is necessary to design a new high-toughness polyetheretherketone medical catheter winding device and working method.

[0066] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0068] Research has found that the disadvantage of the prior art is that the catheter needs to be tensioned during the winding process to ensure the winding effect. However, as the number of winding layers increases, the length of each layer of the catheter increases, and the position of the tensioning device is fixed, resulting in an increase in the pulling force on the catheter that has not been wound, which will cause the catheter to deform and affect the quality of the catheter.

[0069] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0070] like Figure 1 As shown, in at least one disclosed embodiment, a high-toughness polyetheretherketone medical catheter winding device is provided, comprising: a winding device 1 and a tensioning device 2; the tensioning device 2 is arranged before the feeding end of the winding device 1, and the catheter 5 is wound up by the winding device 1 after passing through the tensioning device 2; wherein the tensioning device 2 comprises: a rotating mechanism; the rotating mechanism is rotatably arranged on a support frame 6, and the catheter 5 is wound up by the winding device 1 after passing through the rotating mechanism, and the winding position of the winding device 1 is lower than the position where the catheter 5 passes through the rotating mechanism, and the rotating mechanism rotates during the winding process, and the position where the catheter 5 passes through the rotating mechanism is lowered accordingly, so that the position where the catheter 5 passes through the rotating mechanism is gradually lowered; to achieve During the winding process, as the number of layers of the wound conduit 5 increases, the rotating mechanism rotates accordingly to reduce the tension on the conduit 5, thereby avoiding excessive pulling force on the conduit 5 due to the increase in the number of wound layers, thereby avoiding deformation and damage of the conduit 5; the rotation of the rotating mechanism will cause the top of the rotating mechanism to approach the winding device 1. As the number of wound layers of the conduit 5 increases, the length of each layer of the conduit 5 increases. When the winding speed of the conduit 5 remains unchanged from the conveying speed, the pulling force on the conduit 5 due to winding will increase. At this time, the tension on the conduit 5 is reduced by rotating the rotating mechanism, thereby reducing the impact of the increased pulling force on the conduit 5, thereby avoiding deformation and damage of the conduit 5.

[0071] like Figure 2As shown, in an optional embodiment, the rotating mechanism includes: a tensioning strip 21 and a rotating shaft 22; the rotating shaft 22 is rotatably connected to the support frame 6, and a torsion spring is connected between the rotating shaft 22 and the support frame 6; the tensioning strip 21 is connected to the rotating shaft 22, and a through hole 23 for passing the catheter 5 is opened on the tensioning strip 21; the diameter of the through hole 23 is larger than the diameter of the catheter 5; when the tensioning strip 21 is vertical, the bottom of the catheter 5 contacts the inner bottom surface of the through hole 23, and the position of the through hole 23 is higher than the winding position of the winding device 1; in the initial state, the tensioning strip 21 is in a vertical state, and the through hole 23 is close to the top of the tensioning strip 21, and the catheter 5 passes through the through hole 23. At this time, the catheter 5 is tensioned by the tensioning strip 21 and arched, and the winding position of the winding device 1 is the position where each layer of the catheter 5 starts to wind. In the initial position, The end of the catheter 5 is manually fixed on the winding roller 11, and then the winding is started. As the winding increases, the pulling force on the catheter 5 increases, and the catheter 5 will drive the tensioning strip 21 to rotate. The top of the tensioning strip 21 rotates downward, and the top of the tensioning strip 21 is close to the winding device 1, thereby reducing the tensioning force of the tensioning strip 21 on the catheter 5. By reducing the tensioning force, the deformation of the catheter 5 caused by the increase in the pulling force is avoided; the torsion spring can be used to make the rotating shaft 22 have a maximum rotation angle, that is, the tensioning strip 21 has a maximum rotation angle, for example, the angle between the final position and the initial position of the tensioning strip 21 is 45 degrees, etc. The maximum rotation angle of the rotating shaft 22 can be adjusted by replacing the torsion spring. After the tensioning strip 21 rotates to the final position, the increased pulling force on the catheter 5 can no longer drive the tensioning strip 21 to rotate.

[0072] In an optional embodiment, the tensioning strip 21 is connected to a limiting ring 24 via a connecting strip 25 on the side away from the winding position, and the inner diameter of the limiting ring 24 is adapted to the diameter of the catheter 5; the limiting ring 24 is parallel to the through hole 23, so that the catheter 5 passes through the limiting ring 24 first and then through the through hole 23; the limiting ring 24 can prevent the catheter 5 from shaking, etc.

[0073] like Figure 3 As shown, in an optional embodiment, a pair of grooves 26 are opened near the top of the through hole 23, and a cutting mechanism 3 is rotatably arranged in the groove 26; a portion of the cutting mechanism 3 extends out of the groove 26 and is located in the through hole 23; the cutting mechanism 3 can cut the surface of the catheter 5 as the winding roller 11 continues to wind after the tensioning strip 21 rotates to the maximum extent.

[0074] like Figure 4As shown, in an optional embodiment, the cutting mechanism 3 includes: a cutting block 31 and a protective sleeve 32; the cutting block 31 is rotatably arranged in the groove 26; the protective sleeve 32 is sleeved on the cutting block 31; a gear 33 is arranged on the cutting block 31; the inner bottom surface of the protective sleeve 32 is a rack, and the rack is meshed with the gear 33; the tip of the cutting block 31 extends out of the groove 26 and is located in the through hole 23; when the cutting block 31 rotates, the protective sleeve 32 is moved by the cooperation of the rack and the gear 33, and the length of the cutting block 31 exposing the protective sleeve 32 is adjusted. When the tensioning strip 21 rotates to the maximum angle, the tip of the cutting block 31 extends out of the protective sleeve 32 and contacts the catheter 5 and cuts the catheter 5; Figure 7 As shown, when the tensioning strip 21 is in the initial vertical state, the catheter 5 contacts the inner bottom surface of the through hole 23, and there is space between the catheter 5 and the inner top surface of the through hole 23. At this time, the cutting block 31 is in an inclined state due to its own weight and the weight of the protective cover 32. The protective cover 32 completely wraps the cutting block 31, that is, the tip of the cutting block 31 is also wrapped by the protective cover 32. The bottom edge of the protective cover 32 located at the outer end of the groove 26 contacts the upper half of the surface of the catheter 5. The contact of the two cutting mechanisms 3 on the surface of the catheter 5 can slightly open the surface of the catheter 5, which is convenient for identifying defects after taking an image. At this time, the tip of the cutting block 31 is wrapped to prevent the cutting block 31 from cutting the catheter 5. The edge of the bottom of one end of the protective cover 32 extending out of the groove 26 can be an arc shape to prevent scratches from being formed on the surface of the catheter 5 when the catheter 5 is rolled up. As the number of layers of the catheter 5 rolled up increases, the tensioning strip 21 begins to rotate (the direction of rotation is as shown in FIG. 2 ). Figure 7 As shown in F in the figure, at this time, the conduit 5 in the through hole 23 starts to move upward, that is, the conduit 5 gradually approaches the top of the inner wall of the through hole 23, as shown in FIG. Figure 8 As shown, when the tensioning strip 21 rotates to the maximum angle, the conduit 5 contacts the top edge of the through hole 23 close to the winding device 1. When the conduit 5 moves upward, it drives the cutting block 31 to rotate. When the cutting block 31 rotates, the gear 33 cooperates with the rack, so that the protective cover 32 moves to the inside of the groove 26, so that the tip of the cutting block 31 is exposed from the protective cover 32. When the tensioning strip 21 rotates to the maximum angle, the tip of the cutting block 31 contacts the outer wall of the conduit 5. As the winding continues to increase, the tensioning strip 21 cannot continue to rotate. At this time, the increased pulling force cooperates with the edge of the through hole 23 to deform the conduit 5 in the through hole 23 ( That is, pulling the catheter 5 will cause the catheter 5 to deform after contacting the edge of the through hole 23), and the catheter 5 changes from a circle to an ellipse. At this time, the tip of the cutting block 31 that contacts the outer wall of the catheter 5 will cut the outer wall of the catheter 5; the cutting block 31 is arranged in the upper half of the through hole 23, so that the tip of the cutting block 31 will not be separated from the catheter 5 when the catheter 5 is deformed, thereby ensuring the cutting effect of the cutting block 31; the inner top surface of the groove 26 can face the maximum position of the cutting block 31 when it rotates upward. For example, when the cutting block 31 rotates upward to the highest position, the two cutting blocks 31 are on the same straight line, and at this time they can be parallel to the top surface of the tensioning strip 21.

[0075] like Figure 5 As shown, in an optional embodiment, the winding device 1 includes: a winding roller 11 and a pair of baffles 12; the winding roller 11 is rotatably set on the support frame 6; the baffle 12 is set on the winding roller 11, and the two baffles 12 are arranged opposite to each other, and the distance between the two baffles 12 is adapted to the diameter of the catheter 5; the winding roller 11 is driven to rotate by a driving motor; the catheter 5 is wound on the winding roller 11; the driving motor can drive the winding roller 11 to rotate to roll up the catheter 5, and the baffle 12 can ensure that the catheter 5 is rolled up layer by layer to prevent the catheter 5 from deviating.

[0076] In an optional embodiment, a photographing device 4 is also provided on the support frame 6, and the photographing device 4 is electrically connected to the control module; the photographing device 4 is arranged above the tensioning strip 21; the photographing device 4 is suitable for photographing the image of the catheter 5; the control module is suitable for judging whether there are defects on the catheter 5 and judging whether the catheter 5 is cut according to the image of the catheter 5.

[0077] like Figure 6 As shown, in an optional embodiment, the shooting device 4 includes: a camera 41 and a fill light 42; the camera 41 is arranged on the support frame 6; the camera 41 is arranged above the tension strip 21; the fill light 42 is arranged on the support frame 6, the fill light 42 is arranged above the tension strip 21, and the fill light 42 is arranged obliquely; the control module is electrically connected to the camera 41 and the fill light 42, the control module is suitable for controlling the fill light 42 to light up to illuminate the shooting area of ​​the camera 41, and the control module is suitable for controlling the camera 41 to capture the image of the catheter 5; the support strip is suitable for being made of transparent material; the fill light 42 can illuminate the image of the catheter 5 through the transparent tension strip 21 The catheter 5 in the through hole 23 can be illuminated by the fill light 42, and the irradiation range of the fill light 42 can cover all areas where the tension strip 21 rotates from the initial position to the final position, ensuring real-time shooting during the winding process. The shooting range of the camera 41 can also cover all areas where the tension strip 21 rotates from the initial position to the final position. The fill light 42 can supplement the light to facilitate high-precision photography, making subsequent image recognition more accurate. The camera 41 can capture the image of the catheter 5 through the transparent tension strip 21; the camera 41 can capture the image of the upper half of the catheter 5 when it is horizontal, so as to perform image recognition on the upper half of the catheter 5 to identify defects and cuts.

[0078] In an optional embodiment, the control module is electrically connected to the drive motor in the winding device 1; the control module is suitable for controlling the drive motor to work; the control module is suitable for controlling the drive motor to stop working when it is determined that there is a defect on the catheter 5 according to the image of the catheter 5, and controlling the drive motor to stop working when it is determined that the catheter 5 is cut; when the cutting block 31 cuts the outer wall of the catheter 5, it is determined that the winding has reached the maximum number of layers, and the winding is completed, and the control module controls the drive motor to stop the rotation of the winding roller 11 (the control module can delay for a period of time before controlling the drive motor to stop the rotation of the winding roller 11, so that the cut formed by the cutting block 31 has a certain length, which is convenient for subsequent manual cutting of the catheter from the middle of the cut. ), at this time, the catheter 5 can be cut manually, and the cutting position is located at the catheter 5 corresponding to the cutting mark. At this time, the cutting mark formed by the cutting block 31 is partially located on the rolled-up catheter 5, and partially located on the unrolled catheter 5. The cut mark on the unrolled catheter 5 can facilitate the fixation of the end of the catheter 5, that is, the end of the catheter 5 can be fixed on the winding roller 11 through the cut mark, which is convenient for starting the winding of a new catheter 5. For example, there is a block on the winding roller 11 that can be stuck in the cut mark; after identifying the defect, the control module can also control the drive motor to stop the rotation of the winding roller 11. At this time, the control module can send defect identification information to the staff through the alarm module, etc., to avoid the defective catheter 5 from being wound up.

[0079] In at least one other disclosed embodiment, a working method using the above-mentioned high-toughness polyetheretherketone medical catheter winding device is also provided, including: the catheter 5 is wound up by the winding device 1 after passing through the rotating mechanism, and the rotating mechanism rotates during the winding process so that the position where the catheter 5 passes through the rotating mechanism is gradually lowered.

[0080] In summary, the high-toughness polyetheretherketone medical catheter winding device comprises: a winding device 1 and a tensioning device 2; the tensioning device 2 is arranged before the winding device 1, and the catheter 5 is wound up by the winding device 1 after passing through the tensioning device 2; wherein the tensioning device 2 comprises: a rotating mechanism; the rotating mechanism is rotatably arranged on the support frame 6, and the catheter 5 is wound up by the winding device 1 after passing through the rotating mechanism, and the winding position of the winding device 1 is lower than the position where the catheter 5 passes through the rotating mechanism, and the rotating mechanism rotates during the winding process so that the position where the catheter 5 passes through the rotating mechanism is gradually lowered; it is achieved that during the winding process, as the number of layers of the wound catheter 5 increases, the rotating mechanism rotates accordingly, and the position where the catheter 5 passes through the rotating mechanism is lowered accordingly, so as to reduce the tension on the catheter 5, avoid excessive tension on the catheter 5 due to the increase in the number of winding layers, and thereby avoid deformation and damage of the catheter 5.
