Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a guide wire dipping mechanism, a guide wire coating and curing device, and a guide wire coating and curing method. Background Art

[0002] Guidewire is a commonly used interventional device in the medical field. It reaches the target site by inserting into the lumen of the human body. The surface of the guidewire is evenly coated with a special coating layer, so that the guidewire can blend into the human body environment.

[0003] Before leaving the factory, the guide wire is dipped and cured in the coating and curing device to form a finished guide wire.

[0004] In the existing guide wire dipping device, the immersion tube is filled with a special coating liquid and is L-shaped or straight. The immersion tube is located directly below the guide wire, and a wire feeding mechanism is installed on the side of the guide wire. During immersion, the wire feeding mechanism clamps the guide wire near the opening of the immersion tube and feeds the guide wire into the immersion tube in sections: the wire feeding mechanism first clamps the guide wire and moves it to the opening of the immersion tube, then releases the guide wire away from the opening of the immersion tube, continues to clamp the guide wire and moves it to the opening of the immersion tube... Repeatedly perform the clamping-relaxing action, so as to feed the guide wire into the immersion tube in sections. After the guide wire is completely immersed in the liquid, the guide wire is taken out, and the coating layer of the guide wire is dried and solidified.

[0005] The existing guide wire dipping method and guide wire dipping device have the following disadvantages:

[0006] (1) If a straight immersion tube is used, when the guide wire is long, for example, 1500 mm, the immersion tube also needs to be at least 1500 mm, which makes the overall height of the equipment large and the space utilization rate low;

[0007] (2) If an L-shaped immersion tube is used, the guide wire will pass through the bend of the L-shaped immersion tube during immersion, thereby increasing the immersion resistance of the guide wire; and the immersion tube is laid flat under the guide wire, resulting in a larger device footprint;

[0008] (3) The wire feeding mechanism is complex and the equipment cost is high. In addition, the wire feeding mechanism repeatedly moves up and down to feed the wire in sections during the wire feeding process, which reduces the wire feeding efficiency and also reduces the coating efficiency of the guide wire.

[0009] For the curing process after the guide wire is dipped, the existing equipment mainly provides two curing methods:

[0010] In the first method, the light source and the guide wire are fixed, and the light source area can cover the entire guide wire.

[0011] Disadvantages of this method:

[0012] (1) The overall cost is high. The required LED light source area is large, and the price of LED light source increases with the area. In addition, the increase in the area of ​​the LED light source makes heat dissipation difficult, and the cost of water cooling increases;

[0013] (2) Low production efficiency. The coating time for each batch of guide wires is the sum of the time for loading, dipping, curing and unloading, and there is no overlap between the time of each process;

[0014] (3) The number of guide wires cured in a single batch is greatly limited by the width of the light source. Due to the high cost of the light source, it is impossible to improve production efficiency by greatly increasing the number of guide wires produced in a single batch. In addition, the increase in the number of guide wires will also lead to an increase in the size of the equipment and difficulties in loading and unloading.

[0015] (4) The utilization rate of the light source is low. The light source is turned off or on standby during unloading, loading, and dipping. The time interval between two light source curing is long.

[0016] In the second method, the light source moves, the guide wire is fixed, and the light source scans and illuminates the guide wire.

[0017] Although this method reduces the size of the light source, it has the following disadvantages:

[0018] (1) The curing time of the edge and the middle area is different, and the coating quality in different areas is different;

[0019] (2) During the irradiation process, the scattering of ultraviolet light affects the coating of the guide wires on both sides;

[0020] (3) There are light instability factors when the LED light source moves.

[0021] Therefore, how to provide a guide wire dipping mechanism, a guide wire coating and curing device and a guide wire coating and curing method that can improve equipment space utilization and improve guide wire dipping and guide wire curing efficiency is a technical problem that needs to be solved in the field.

It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, and are not intended to exhaust all possible modes of the present invention, nor to limit the scope of the present invention.

[0092] Refer to the following Figure 1-6 , introduces the specific structure of the guide wire dipping mechanism and the guide wire coating and curing device according to the present invention and the guide wire coating and curing method.

[0093] First refer to Figure 1-3 , the main structure of the guide wire dipping mechanism according to the present invention is introduced.

[0094] Guide wire dipping mechanism

[0095] A guide wire clamp 1 is provided on the upper part of the frame of the guide wire dipping mechanism, and the guide wire clamp 1 has a plurality of guide wire clamping stations 101, each of which can be used to clamp a guide wire G. During the guide wire dipping operation, one end of the guide wire G is clamped by the guide wire clamping station 101, and the other end of the guide wire G hangs down naturally.

[0096] The first reversing roller group 501 and the second reversing roller group 502 are arranged at the lower part of the frame of the guide wire dipping mechanism. A group of immersion tubes 2 successively bypass the first reversing roller group 501 and the second reversing roller group 502. The number of immersion tubes 2 is the same as the number of guide wire clamping stations 101. The immersion tubes 2 are flexible hoses. The inside of the immersion tubes 2 is used to hold the coating liquid for dipping the guide wire G. The first end 201 of the immersion tube 2 extends upward after bypassing the first reversing roller group 501; the second end 202 of the immersion tube 2 extends upward after bypassing the second reversing roller group 502. In the horizontal direction, the side of the first reversing roller group 501 facing the guide wire clamping member 1 is defined as the "working area" of the guide wire dipping mechanism, and the side of the second reversing roller group 502 away from the guide wire clamping member 1 is defined as the "preparation area" of the guide wire dipping mechanism. The immersion tube 2 can reciprocate under the guidance of the first reversing roller group 501 and the second reversing roller group 502. During the reciprocating movement, the immersion tube 2 forms a "first immersion tube movement path" extending in the vertical direction in the working area, a "second immersion tube movement path" extending in the vertical direction in the preparation area, and a "third immersion tube movement path" extending horizontally between the first reversing roller group 501 and the second reversing roller group 502. The first immersion tube movement path, the second immersion tube movement path, and the third immersion tube movement path form a U shape, that is, the immersion tube 2 moves as a whole in a U-shaped path. When the first end 201 of the immersion tube moves upward along the first immersion tube movement path, the second end 202 of the immersion tube moves downward along the second immersion tube movement path; when the first end 201 of the immersion tube moves downward along the first immersion tube movement path, the second end 202 of the immersion tube moves upward along the second immersion tube movement path. It should be understood that in other possible embodiments, the number of reversing rollers may not be limited to two / groups; for example, only one / group of reversing rollers may be provided to enable the immersion tube 2 to move along a U-shaped path (consisting of a vertical "immersion tube first movement path" and a vertical "immersion tube second movement path") that does not have a horizontal immersion tube third movement path; or, only one / group of reversing rollers may be provided to enable the immersion tube 2 to move along a roughly L-shaped path (consisting of a vertical "immersion tube first movement path" and a horizontal "immersion tube third movement path") that does not have a vertical immersion tube second movement path; or, three / groups or more of reversing rollers may be provided to be distributed on the movement path of the immersion tube 2 to provide better guidance for the immersion tube 2.

[0097] The first end 201 of the immersion tube is open and connected to the outside air, and the second end 202 of the immersion tube has a closed structure. Under the action of atmospheric pressure, the first end 201 of the immersion tube moves to any position on the first movement path of the immersion tube, and the coating liquid inside the immersion tube 2 will not overflow. Preferably, a sealing cover that can be selectively opened and closed is provided on the second end 202 of the immersion tube. When the sealing cover is opened, the first end 201 of the immersion tube and the second end 202 of the immersion tube are both connected to the outside air, which is convenient for replenishing the coating liquid to the immersion tube 2; it should be understood that the sealing cover can also be set at any position in the length direction of the immersion tube, not limited to the second end 202 of the immersion tube. Preferably, the second ends 202 of the immersion tubes of multiple immersion tubes 2 are interconnected to facilitate replenishing the coating liquid to multiple immersion tubes 2 at the same time.

[0098] To facilitate the synchronous movement of multiple immersion tubes 2, the first ends 201 of the immersion tubes 2 are fixed to the work area assembly 3, and the second ends 202 of the immersion tubes 2 are fixed to the preparation area assembly 4. Optionally, the work area assembly 3 and the preparation area assembly 4 are plate-like structures, and the panel of the work area assembly 3 is provided with through holes of the same number as the immersion tubes 2 to form multiple work area assembly openings 301, and each work area assembly opening 301 is connected to the first end 201 of the immersion tube 2. Each work area assembly opening 301 / immersion tube first end 201 is aligned with a guide wire clamping station 101 in the vertical direction, so that when the work area assembly 3 moves upward, a guide wire G clamped on each guide wire clamping station 101 can extend into an immersion tube 2. Preferably, the preparation area assembly 4 is provided with a connecting port connected to the second end 202 of the immersion tube, and a sealing cover is arranged on the connecting port.

[0099] An immersion tube guide is provided between the upper panel 1001 and the lower panel 1002 of the frame of the guide wire dipping mechanism, and the immersion tube guide includes a lead screw 601, a lead screw nut 602 and a lead screw driver. The lead screw driver can be any driving device for driving the lead screw to rotate in the prior art, such as a motor. The working area assembly 3 is connected to the lead screw nut 602, so that it can follow the lead screw nut 602 and reciprocate up and down along the lead screw 601 under the drive of the lead screw driver. In order to facilitate the smooth movement of the second end 202 of the immersion tube fixed to the preparation area assembly 4 and the first end 201 of the immersion tube fixed to the working area assembly 3, preferably, the immersion tube guide also includes: a pulley 603 and a cable (not shown in the figure). Preferably, there are two groups of pulleys 603, which are respectively arranged on the frames above the working area assembly 3 and the preparation area assembly 4. After the cable passes around the two groups of pulleys 603, the two ends of the cable are respectively connected to the working area assembly 3 and the preparation area assembly 4. When the working area assembly 3 moves as an active moving part relative to the preparation area assembly 4, the tensioned cable plays an auxiliary traction role on the preparation area assembly 4, and this traction effect is particularly effective when the working area assembly 3 moves downward. In order to constrain the movement path of the preparation area assembly 4, preferably, the immersion tube guide also includes a guide rod 604, and the guide rod 604 is vertically arranged between the upper panel 1001 of the rack and the lower panel 1002 of the rack, and the preparation area assembly 4 is provided with a guide hole or a guide groove that cooperates with the guide rod 604. In order to accurately control the start and stop of the up and down movement of the working area assembly 3, an upper photoelectric switch and a lower photoelectric switch are respectively arranged on the rack. The upper and lower photoelectric switches are respectively located at the upper and lower ends of the movement path of the working area assembly 3, and serve as the upper limit and lower limit of the movement of the working area assembly 3. When the working area assembly 3 moves to the vicinity of the upper photoelectric switch / lower photoelectric switch, the upper photoelectric switch / lower photoelectric switch is actuated, and the working area assembly 3 stops rising / falling.

[0100] Preferably, each guide wire clamping station 101 can rotate around its vertical central axis, and the rotation of the guide wire clamping station 101 is achieved by a conventional driving device capable of driving components to rotate in the prior art, such as a motor. During the process of the guide wire G extending into the coating liquid of the immersion tube 2 for the immersion process, the guide wire clamping station 101 rotates, driving the guide wire G to rotate around its own axis, thereby reducing the resistance of the guide wire G to enter the coating liquid. Preferably, when there are multiple guide wire clamping stations 101, a main drive motor is set to provide a rotational driving force, and under the drive of the main drive motor, the multiple guide wire clamping stations 101 transmit the rotational driving force to each other (for example, through gear transmission) and rotate synchronously.

[0101] The following reference Figure 4-6 , introduces the main structure of the guide wire coating and curing device composed of the guide wire dipping mechanism according to the present invention.

[0102] Guidewire coating and curing device

[0103] The coating and curing operation of the guide wire includes dipping and curing; wherein the dipping process requires a guide wire dipping mechanism, and the curing process requires a guide wire curing light source. In order to improve the efficiency of the guide wire coating operation, the guide wire coating and curing device of the present invention includes at least two guide wire dipping mechanisms and at least one guide wire curing light source. Preferably, the two guide wire dipping mechanisms share one guide wire curing light source, thereby forming two workstations, one workstation performs the dipping process while the other workstation performs the curing process, thereby improving the utilization rate of the equipment.

[0104] Reference Figure 4 , define the L direction in the figure as the length direction of the guide wire coating and curing device, the W direction in the figure as the width direction of the guide wire coating and curing device, and the H direction in the figure as the height direction of the guide wire coating and curing device (the above definitions are only for the convenience of description, and there is no restriction on the dimensional relationship between the device in the length direction, width direction and height direction). A guide wire curing light source 7 is arranged in the middle area in the length direction of the guide wire coating and curing device. Preferably, the guide wire curing light source 7 is an LED light source. A first guide wire dipping mechanism M1 and a second guide wire dipping mechanism M2 are respectively arranged on both sides of the guide wire curing light source 7 in the length direction. Preferably, the first guide wire dipping mechanism M1 and the second guide wire dipping mechanism M2 have the same structure (hereinafter, when one of the first guide wire dipping mechanism M1 or the second guide wire dipping mechanism M2 is not emphasized, it is also referred to as "guide wire dipping mechanism"). The first guide wire clamp 11 from the first guide wire dipping mechanism M1 and the second guide wire clamp 12 from the second guide wire dipping mechanism M2 can reciprocate in the length direction relative to the guide wire curing light source 7. The length dimension of the guide wire curing light source 7 is roughly equal to or slightly larger than the length dimension of the guide wire clamp of the guide wire dipping mechanism. The height dimension of the guide wire curing light source 7 is roughly equal to or slightly larger than the length of the guide wire. Therefore, the guide wire curing light source 7 can cure a group of guide wires from the first guide wire clamp 11 or the second guide wire clamp 12 each time. Figure 4 In the mid-length direction, the area where the first guide wire dipping mechanism M1 is located is defined as the "first dipping station", the area where the second guide wire dipping mechanism M2 is located is defined as the "second dipping station", and the area where the curing light source 7 is located is defined as the "curing station".

[0105] The following combination Figure 6 , an implementation manner in which the first guide wire clamp 11 and the second guide wire clamp 12 reciprocate relative to the guide wire curing light source 7 in the length direction is introduced.

[0106] The light source irradiation direction of the curing light source 7 is defined as the "front" side of the device, and the direction opposite to the front side is defined as the "rear" side of the device. On the device frame in front of the curing light source 7, a guide wire clamp translation rail 801 is provided, and the guide wire clamp translation rail 801 extends from the first dipping station across the curing station to the second dipping station. The first guide wire clamp 11 and the second guide wire clamp 12 can both reciprocate along the guide wire clamp translation rail 801; the first guide wire clamp 11 reciprocates along the guide wire clamp translation rail 801 between the first dipping station and the curing station under the drive of the first translation motor 802, and the second guide wire clamp 12 reciprocates along the guide wire clamp translation rail 801 between the second dipping station and the curing station under the drive of the second translation motor 803. Preferably, the output ends of the first translation motor 802 / the second translation motor 803 are respectively provided with a gear 8021 and a gear 8031, and the gear 8021 and the gear 8031 ​​can move along a rack rail 804 fixed to the device frame. It should be understood that the first translation motor 802 and the second translation motor 803 can also be replaced by other driving devices for driving linear motion in the prior art, such as a cylinder, a hydraulic cylinder, etc.

[0107] Reference Figure 4 Preferably, a first shielding member 901 is provided between the first dipping station and the curing station, and a second shielding member 902 is provided between the second dipping station and the curing station, and the first shielding member 901 and the second shielding member 902 have a roughly plate-shaped appearance. The first shielding member 901 and the second shielding member 902 can be selectively opened and closed respectively. When the first shielding member 901 / the second shielding member 902 are opened, the first guide wire clamping member 11 / the second guide wire clamping member 12 can reciprocate between the first dipping station / the second dipping station and the curing station; when the first shielding member 901 and the second shielding member 902 are closed, the light emitted by the guide wire curing light source 7 can be blocked at the guide wire curing station, so as to improve the utilization rate of the light source in the curing process.

[0108] The following combination Figure 6, an implementation method of selectively opening and closing the first shielding member 901 and the second shielding member 902 is introduced. A first shielding member translation rail 903 extending horizontally along the width direction of the device is provided between the first dipping station and the curing station; a second shielding member translation rail 904 extending horizontally along the width direction of the device is provided between the second dipping station and the curing station. The track length of the first shielding member translation rail 903 / the second shielding member translation rail 904 (the dimension of the track in the width direction of the device) is greater than the dimension of the first shielding member 901 / the second shielding member 902 in the width direction of the device. The first shielding member 901 and the second shielding member 902 reciprocate along the first shielding member translation rail 903 and the second shielding member translation rail 904 respectively under the drive of the first shielding member translation motor 905 and the second shielding member translation motor 906. When the first shielding member 901 / the second shielding member 902 moves to the front end of the first shielding member translation rail 903 / the second shielding member translation rail 904, the first shielding member 901 / the second shielding member 902 is in a "closed" state; when the first shielding member 901 / the second shielding member 902 moves to the rear end of the first shielding member translation rail 903 / the second shielding member translation rail 904, the first shielding member 901 / the second shielding member 902 is in an "opened" state. Preferably, the output ends of the first shielding member translation motor 905 / the second shielding member translation motor 906 are provided with a gear 9051 and a gear 9061, respectively, and the gear 9051 and the gear 9061 can move along a rack rail 9052 and a rack rail 9062 fixed to the device frame, respectively. It should be understood that the first shielding member translation motor 905 / the second shielding member translation motor 906 may also be replaced by other driving devices for driving linear motion in the prior art, such as a pneumatic cylinder, a hydraulic cylinder, and the like.

[0109] It should be understood that the selective opening and closing of the first shielding member 901 and the second shielding member 902 can also be achieved by other means. For example, the first shielding member 901 / the second shielding member 902 can have a flexible structure (for example, foldable or rollable). This flexible structure enables the first shielding member 901 / the second shielding member 902 to be unfolded in the width direction of the device to block the light emitted by the guide wire curing light source 7 at the guide wire curing station. At this time, the first shielding member 901 / the second shielding member 902 is in a "closed" state; this flexible structure also enables the first shielding member 901 / the second shielding member 902 to be retracted in the width direction of the device like a pull-type curtain. At this time, the first shielding member 901 / the second shielding member 902 is in an "open" state.

[0110] Dual-station guide wire coating and curing method

[0111] The working process of the guide wire coating and curing device with two working stations (double-station guide wire coating and curing device) of the present invention is introduced below.

[0112] (i) In the preparation stage for coating, the first guide wire clamp 11 and the second guide wire clamp 12 are respectively located at the first dipping station and the second dipping station, and the following operations are performed:

[0113] Adding liquid: Start the screw drive to make the working area collection part 3 and the preparation area collection part 4 of the guide wire dipping mechanism basically at the same height, open the sealing cover, add the coating liquid to the dipping tube 2, and then close the sealing cover. Make the working area collection part 3 drop to the bottom of the guide wire dipping mechanism to facilitate the subsequent steps of guide wire loading.

[0114] Guide wire loading: fix one end of the first group of guide wires to be coated (hereinafter also referred to as the first-station guide wires) to the guide wire clamp of the first guide wire dipping mechanism M1, and let the other end hang naturally; fix one end of the second group of guide wires to be coated (hereinafter also referred to as the second-station guide wires) to the guide wire clamp of the second guide wire dipping mechanism M2, and let the other end hang naturally.

[0115] (II) In the initial operation stage of the double-station coating and curing operation, the following operations are performed:

[0116] First station guide wire dipping:

[0117] The working area summary component 3 of the first guide wire dipping mechanism rises to the upper limit position, and the first station guide wire is immersed in the coating liquid in the immersion tube 2 for a certain period of time; the working area summary component 3 of the first guide wire dipping mechanism descends to the lower limit position, so that the first station guide wire leaves the immersion tube 2.

[0118] (III) During the cycle operation phase of the double-station coating and curing operation, the following operations are performed:

[0119] S1, the first station is for wire curing, and the second station is for wire dipping:

[0120] The first shielding member 901 is opened, the first guide wire clamping member 11 moves along the guide wire clamping member translation rail 801 to the curing station, the first shielding member 901 and the second shielding member 902 are closed, the curing light source 7 is turned on, the guide wire at the first station is cured, and the curing light source 7 is turned off after the curing operation is completed;

[0121] At any time during the curing process of the guide wire at the first station,

[0122] The working area summary component 3 of the second guide wire dipping mechanism rises to the upper limit position, so that the second station guide wire is immersed in the coating liquid in the immersion tube 2 for a certain period of time; the working area summary component 3 of the second guide wire dipping mechanism descends to the lower limit position, so that the second station guide wire leaves the immersion tube 2.

[0123] S2, unloading of wire guide at the first station, loading of wire guide at the new first station:

[0124] The first shielding member 901 is opened, and the first guide wire clamping member 11 moves along the guide wire clamping member translation rail 801 to the first dipping station. The first shielding member 901 is closed, and the coated first station guide wire is removed, and one end of the new first station guide wire to be coated is fixed to the first guide wire clamping member 11.

[0125] S3, the second station guide wire is cured, the first station guide wire is dipped:

[0126] The second shielding member 902 is opened, the second guide wire clamping member 12 moves along the guide wire clamping member translation rail 801 to the curing station, the second shielding member 902 is closed, the curing light source 7 is turned on, the second station guide wire is cured, and the curing light source 7 is turned off after the curing operation is completed;

[0127] At any time during the second station guide wire curing process,

[0128] The working area summary component 3 of the first guide wire dipping mechanism rises to the upper limit position, so that the first station guide wire is immersed in the coating liquid in the immersion tube 2 for a certain period of time; the working area summary component 3 of the first guide wire dipping mechanism descends to the lower limit position, so that the first station guide wire leaves the immersion tube 2.

[0129] S4, unloading of wire guide at the second station and loading of wire guide at the new second station.

[0130] The second shielding member 902 is opened, and the second guide wire clamping member 12 moves along the guide wire clamping member translation rail 801 to the second dipping station. The second shielding member 902 is closed, and the coated second station guide wire is removed, and one end of the new second station guide wire to be coated is fixed to the first guide wire clamping member 11.

[0131] Repeat steps S1 to S4 until all guide wires are coated.

[0132] It should be understood that the start of step S2 does not have to wait for the second station guide wire dip coating in step S1 to be completely completed. For example, at a certain moment when the first station guide wire is cured and the second station guide wire is still in the dip coating operation, step S2 can be started to unload the first station guide wire and load the new first station guide wire. Similarly, the start of step S4 does not have to wait for the first station guide wire dip coating in step S3 to be completely completed. In the double-station guide wire coating and curing operation, it is only necessary to ensure that at least in part of the coating and curing process, the first / second station guide wire is performing the dip coating operation while the second / first station guide wire is performing the curing operation, so as to achieve the technical effect of improving the light source utilization rate of the guide wire curing light source of the present invention. Preferably, by controlling the sum of the guide wire loading and dipping time of the first guide wire dip coating mechanism and the sum of the guide wire curing and unloading time of the second guide wire dip coating mechanism, so that the two are basically the same, the operating efficiency of the double-station guide wire coating and curing device according to the present invention can be doubled compared with the traditional single-station guide wire coating and curing device.

[0133] The above embodiments of the present invention can achieve one or more of the following advantages:

[0134] (1) According to the guide wire dipping mechanism of the present invention, the guide wire does not move in the vertical direction during the dipping process, and the guide wire is introduced into the liquid by the dipping tube in a U-shaped movement path, so that the height of the device is reduced and the space utilization rate is high;

[0135] (2) The guide wire is always in a vertical state during the dipping process, and the immersion tube is always in a vertical state in the working area. The guide wire will not encounter any bends when entering the liquid, and the resistance to entering the liquid is small;

[0136] (3) When the immersion tube rises, the guide wire rotates at a low speed, further reducing the resistance of the guide wire entering the liquid;

[0137] (4) The immersion tube has one end open and the other end closed, and atmospheric pressure is used to prevent the coating liquid from overflowing at any position of the immersion tube along the movement path, even if the heights of the two ends are inconsistent;

[0138] (5) The closed ends of the immersion tube group consisting of multiple immersion tubes are connected to facilitate liquid addition;

[0139] (6) In the double-station guide wire coating and curing device, the light source is fixed and the guide wire moves, making the structure of the device simple;

[0140] (7) The double-stations alternately perform dipping and curing of the guide wire, effectively improving the utilization rate of the light source and improving production efficiency; and on the basis of ensuring the curing quality, the light source area is reduced, thereby reducing costs;

[0141] (8) When the guide wire moves from the first dipping station / the second dipping station to the curing station, it will swing slightly due to inertia. This swing allows the guide wire to receive light more evenly during the curing process, so that even when the light source is sparse, all parts of the guide wire can be effectively irradiated.

[0142] It should be understood that the above embodiments are only exemplary and are not intended to limit the present invention. Those skilled in the art may make various modifications and changes to the above embodiments under the guidance of the present invention without departing from the scope of the present invention.

[0143] In addition, it is necessary to explain:

[0144] The guidewire described in the present invention is not limited to being used as a guidewire for medical equipment, but may also be other strip-shaped or tubular objects with a slender structure that require coating, such as a guide wire, a catheter, and the like.
