Technical Field

[0001] This disclosure relates to the field of medical device technology, and more specifically, to a guidewire control device. Background Technology

[0002] In related technologies, existing guidewire pushing devices are limited by their structural form, which makes it inconvenient for operators to use them for guidewire delivery. Summary of the Invention

[0003] The purpose of this disclosure is to provide a guide wire control device that can simultaneously satisfy operations such as forward movement, pause, retraction, and rotation during guide wire delivery, and has the advantages of high applicability and convenient operation.

[0004] To achieve the above objectives, this disclosure provides a guidewire control device, comprising: A first clamping part, on which a first wire feeding roller is movably connected; and The second clamping part is movably connected to a second wire feeding roller, and the second clamping part has a channel for the guide wire to pass through. The first clamping part is configured to be movably connected to the second clamping part, so that the first wire feeding roller has a pushing position and an idle position. In the pushing position, the first wire feeding roller can clamp the guide wire located in the channel with the second wire feeding roller, so that the guide wire can be moved relative to the channel by the rotation of the first wire feeding roller and the second wire feeding roller. In the idle position, the first wire feeding roller is away from the second wire feeding roller relative to the pushing position.

[0005] In some possible implementations, the first wire feeding roller has multiple wire pushing positions relative to the second wire feeding roller, and the gap between the first wire feeding roller and the second wire feeding roller is different at each of the wire pushing positions.

[0006] In some possible implementations, one end of the first clamping part is hinged to the second clamping part, and the other end is provided with a snap-fit ​​structure. The second clamping part is provided with a snap-fit ​​engagement structure, which has multiple snap-fit ​​positions. The first wire feeding roller is switched to different wire pushing positions by snapping the snap-fit ​​structure into different snap-fit ​​positions of the snap-fit ​​engagement structure.

[0007] In some possible implementations, the snap-fit ​​structure includes a base disposed on the second clamping part, the base having a plurality of snap-fit ​​positions arranged at intervals, each snap-fit ​​position having an insertion port and a slot communicating with the insertion port, wherein at the push-wire position, the snap-fit ​​structure can be inserted into the corresponding insertion port and locked in the slot.

[0008] In some possible implementations, the base is fixedly connected to the second clamping portion; or, The second clamping part is provided with a sliding groove, the bottom end of the base is slidably inserted into the sliding groove, and an elastic reset member is provided between the base and the sliding groove. The elastic reset member is used to provide elastic force for the base to move to the position where it is engaged with the snap-fit ​​structure.

[0009] In some possible implementations, the second clamping part includes a housing, and the channel includes a first cavity, a second cavity, and a third cavity disposed within the housing and arranged sequentially in a first direction; Wherein, the first end of the outer casing has a first flared opening communicating with the first cavity, and the inner diameter of the first flared opening gradually decreases toward the side closer to the second cavity; and / or, The first cavity has a second flared opening near the end of the second cavity, which communicates with the second cavity. The inner diameter of the second flared opening gradually decreases towards the side opposite to the second cavity; and / or, The third cavity has a third flared opening at its end near the second cavity, which communicates with the second cavity. The inner diameter of the third flared opening gradually decreases toward the side facing away from the second cavity; and / or, The third cavity has a fourth flared opening on the side opposite to the second cavity. The fourth flared opening is connected to the inlet and outlet of the outer casing at the second end, and the inner diameter of the fourth flared opening gradually decreases toward the side closer to the second cavity.

[0010] In some possible implementations, the maximum inner diameter of the first flared opening is smaller than the maximum inner diameter of the second flared opening; and / or, The maximum inner diameter of the third flared opening is equal to the maximum inner diameter of the fourth flared opening; and / or, The maximum inner diameter of the third flared opening is not less than the maximum inner diameter of the second flared opening.

[0011] In some possible implementations, the second clamping part includes a housing, and the channel includes a first cavity, a second cavity, and a third cavity disposed within the housing and arranged sequentially in a first direction; The second wire feeding roller is located in the second cavity. In the second direction perpendicular to the first direction, both the first cavity and the third cavity have a bottom point, and the second wire feeding roller has a top point. The bottom point and the top point are arranged parallel to each other in the first direction.

[0012] In some possible implementations, the first wire feeding roller includes a first roller and a first friction layer disposed on the outer peripheral wall of the first roller, and the second wire feeding roller includes a second roller and a second friction layer disposed on the outer peripheral wall of the second roller; Wherein, the maximum outer diameter of the first roller is greater than the maximum outer diameter of the second roller; and / or, The maximum thickness of the first friction layer is greater than the maximum thickness of the second friction layer.

[0013] In some possible implementations, the guidewire control device further includes a handle sleeved on the second clamping portion, the handle having a fourth cavity extending through the handle in a first direction and communicating with the channel, the first clamping portion being located outside the handle; In the wire-pushing position, the second clamping part is configured to be able to rotate relative to the handle by an external force, so as to drive the guide wire to rotate around its own central axis by the first wire-feeding roller and the second wire-feeding roller clamped on the guide wire.

[0014] Through the above-described technical solution, namely the guidewire control device provided in this disclosure, the first clamping part is configured to be movably connected to the second clamping part, so that the first wire feeding roller provided on the first clamping part can have a pushing position and an idle position. With this arrangement, for example, when the first wire feeding roller is in the pushing position, it can clamp the guidewire located in the channel together with the second wire feeding roller. This allows the guidewire to move relative to the channel by rotating the first and second wire feeding rollers, achieving operations such as advancing, pausing, and retracting the guidewire. Furthermore, the operator can also rotate the guidewire by operably rotating the first and second clamping parts. Thus, this guidewire control device can be used for, for example, guidewire interventional operations within blood vessels and has high applicability. Additionally, when, for example, the first wire feeding roller is in the idle position, it can be moved away from the second wire feeding roller, facilitating the insertion and replacement of the guidewire through the channel of the second clamping part. Therefore, through the above technical solution, the wire guide control device provided in this disclosure can simultaneously meet operations such as forward movement, pause, retraction, and rotation during the wire guide transport process, and has the advantages of high applicability and convenient operation.

Detailed Implementation

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer contours relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements.

[0020] According to the guidewire control device provided in this disclosure, refer to Figures 1 to 4As shown, the guide wire control device includes a first clamping part 1 and a second clamping part 3. A first wire feeding roller 2 is movably connected to the first clamping part 1. A second wire feeding roller 4 is movably connected to the second clamping part 3, and the second clamping part 3 has a channel 310 for the guide wire 5 to pass through. The first clamping part 1 is configured to be movably connected to the second clamping part 3, so that the first wire feeding roller 2 has a pushing position and an idle position. In the pushing position, the first wire feeding roller 2 can clamp the guide wire 5 located in the channel 310 with the second wire feeding roller 4, so that the guide wire 5 can be moved relative to the channel 310 by the rotation of the first wire feeding roller 2 and the second wire feeding roller 4. In the idle position, the first wire feeding roller 2 is away from the second wire feeding roller 4 compared to the pushing position.

[0021] Through the above-described technical solution, namely the guidewire control device provided in this disclosure, the first clamping part 1 is configured to be movably connected to the second clamping part 3, so that the first wire feeding roller 2 provided on the first clamping part 1 can have a pushing position and an idle position. With this arrangement, for example, when the first wire feeding roller 2 is in the pushing position, it can be clamped together with the second wire feeding roller 4 in the guidewire 5 located in the channel 310, so that the guidewire 5 can be moved relative to the channel 310 by the rotation of the first wire feeding roller 2 and the second wire feeding roller 4, thereby achieving operations such as advancing, pausing and retracting of the guidewire 5. Furthermore, the operator can also achieve the rotation operation of the guidewire 5 by operably rotating the first clamping part 1 and the second clamping part 3. In this way, guidewire intervention operations such as intravascular intervention can be achieved with the help of this guidewire control device, and it has high applicability.

[0022] Furthermore, when, for example, the first wire feeding roller 2 is in an idle position, it can be moved away from the second wire feeding roller 4 to facilitate the threading of the guide wire 5 through the channel 310 of the second clamping part 3, thereby enabling the installation and replacement of the guide wire 5. Therefore, through the above technical solution, the guide wire control device provided by this disclosure can simultaneously satisfy operations such as forward movement, pause, retraction, and rotation during the guide wire conveying process, and has the advantages of high applicability and convenient operation.

[0023] In some possible implementations, refer to Figures 1 to 4 As shown, the first wire feeding roller 2 can have multiple wire pushing positions relative to the second wire feeding roller 4. The gap between the first wire feeding roller 2 and the second wire feeding roller 4 is different at each wire pushing position. With this arrangement, it is possible to install and clamp guide wires 5 of different specifications and sizes by means of a wire guiding control device, which is beneficial to improving the applicability of the wire guiding control device.

[0024] It should be noted that the gap between the first wire feeding roller 2 and the second wire feeding roller 4 at each wire pushing position can be understood as follows: when, for example, the operator can operably rotate the first wire feeding roller 2 to different wire pushing positions, the space between the outer peripheral wall of the first wire feeding roller 2 and the outer peripheral wall of the second wire feeding roller 4 for accommodating the guide wire 5 of the corresponding specification size is formed as described above. Furthermore, as the operator can operably change the position of the first wire feeding roller 2 relative to the second wire feeding roller 4, the size of the space formed between the outer peripheral walls of the first wire feeding roller 2 and the second wire feeding roller 4 can be adaptively adjusted. That is, the size of the gap between the first wire feeding roller 2 and the second wire feeding roller 4 can be adaptively adjusted, thereby enabling the installation and clamping of guide wires 5 of different specifications and sizes.

[0025] Considering that, in order to facilitate operators in arbitrarily switching, for example, the first wire feeding roller 2 between the wire feeding position and the idle position, as well as arbitrarily switching between multiple wire feeding positions, in some possible embodiments, refer to Figures 1 to 4 As shown, one end of the first clamping part 1 can be hinged to the second clamping part 3, and the other end is provided with a snap-fit ​​structure 6. The second clamping part 3 is provided with a snap-fit ​​engagement structure 7. In this way, by hinged one end of the first clamping part 1 to the second clamping part 3, the operator can operate to drive the first clamping part 1 to rotate relative to the second clamping part 3, thereby achieving, for example, arbitrary switching of the first wire feeding roller 2 between the wire pushing position and the idle position, as well as arbitrary switching between multiple wire pushing positions, making the operation more convenient.

[0026] Furthermore, by providing a snap-fit ​​structure 6 at the other end of the first clamping part 1 and adaptively providing a snap-fit ​​engagement structure 7 on the second clamping part 3, the first clamping part 1 can be unclamped onto the second clamping part 3 through a snap-fit ​​connection, thereby achieving the purpose of stably holding the first clamping part 1 at the corresponding wire push position. This method offers high reliability and a simple overall structure, facilitating the installation and replacement of the guidewire 5. In other words, due to the aforementioned snap-fit ​​connection method, the operator can easily complete the opening and closing of the first clamping part 1 with one hand, effectively improving the smoothness, stability, and efficiency of the operation during, for example, guidewire interventional procedures within blood vessels.

[0027] In addition, refer to Figures 1 to 4 As shown, the snap-fit ​​structure 7 can have multiple snap-fit ​​positions. By snapping the snap-fit ​​structure 6 into different snap-fit ​​positions of the snap-fit ​​structure 7, the first wire feeding roller 2 can be switched to different wire pushing positions. This arrangement makes it easy for operators to switch the first wire feeding roller 2 between multiple wire pushing positions, and enables the installation and clamping of guide wires 5 of different specifications and sizes with the help of the wire guide control device, which is beneficial to improving the applicability of the wire guide control device.

[0028] The snap-fit ​​structure 6 and the snap-fit ​​engagement structure 7 can be adaptively designed according to actual application requirements. Their purpose is to stably hold the first clamping part 1 in the corresponding wire-pushing position. For example, in some possible implementations, refer to... Figures 1 to 4 As shown, the snap-fit ​​structure 7 may include a base 710 disposed on the second clamping part 3. The base 710 is provided with a plurality of snap-fit ​​positions arranged at intervals. Each snap-fit ​​position is provided with an insertion port 711 and a slot 712 communicating with the insertion port 711. In the push-wire position, the snap-fit ​​structure 6 can be inserted into the corresponding insertion port 711 and locked in the slot 712. In this way, by locking the snap-fit ​​structure 6 in the slot 712 at the corresponding snap-fit ​​position, the first clamping part 1 can be unlockably snapped into the second clamping part 3. The overall structure is simple and the operator can easily complete the opening and unlocking operation of the first clamping part 1 with one hand.

[0029] in, Figures 1 to 4 As exemplarily shown, along the height direction of the base 710 (see, for example) Figure 2 The slots 712 (perpendicular to the second direction of the first direction) can be arranged in multiple intervals, and each slot 712 has a spring buckle 713 protruding from the plane of the opening of the slot 712 at its outer end away from the base 710. The gap between each spring buckle 713 and the outer wall of the adjacent slot 712 forms the aforementioned insertion port 711. The snap-fit ​​structure 6 includes a snap buckle 610 provided on the first clamping part 1. Thus, at the corresponding push wire position, the snap buckle 610 can be snapped into the corresponding slot 712 through the insertion port 711 and engage with the spring buckle 713, thereby achieving the purpose of unlockably snapping the first clamping part 1 into the second clamping part 3. This method is highly reliable and easy to operate.

[0030] It should be noted that those skilled in the art can adapt the specific structure of the buckle 610 and the spring buckle 713 according to the actual application requirements. This disclosure does not make specific limitations in this regard. The purpose is to achieve the snap-fit ​​cooperation between the buckle 610 and the spring buckle 713 so that the first clamping part 1 can be unlockably snapped into the second clamping part 3.

[0031] Additionally, in some possible implementations, refer to Figures 1 to 4As shown, a sliding groove 320 can be provided on the second clamping part 3. The bottom end of the base 710 is slidably inserted into the sliding groove 320, and an elastic reset member 8 is provided between the base 710 and the sliding groove 320. The elastic reset member 8 is used to provide elastic force for the base 710 to move to the position where it is engaged with the snap-fit ​​structure 6. With this arrangement, when the operator, for example, operably moves the base 710 to slide in the sliding groove 320 and compresses the elastic reset member 8, it can achieve, for example, snap the buckle 610 into the corresponding slot 712 and engage with the spring buckle 713, or, for example, snap the buckle 610 located in the slot 712 and engaged with the spring buckle 713 to the outside of the slot 712, thereby achieving the purpose of snap-fit ​​fixing or opening and unlocking operation of the first clamping part 1. After the operator removes the external force, the base 710 can also automatically reset under the elastic force of the elastic reset member 8, making the operation convenient.

[0032] It should be noted that in some embodiments not shown, the base 710 may be, for example, arranged in an inverted "T" shape. In this way, by sliding the bottom end of the inverted "T" shaped base 710 into the slide groove 320, the risk of the base 710 detaching from the slide groove 320 can be reduced when, for example, an operator can maneuver the base 710 to slide within the slide groove 320, making operation easier and more reliable. This disclosure is not limited thereto.

[0033] In addition, by way of example, the above-mentioned elastic reset member 8 may include, but is not limited to, springs, sheet metal or elastic blocks provided between the base 710 and the slide groove 320, which are elastic bodies that have the elastic force to move the base 710 to the position of engaging with the engaging structure 6. This disclosure does not specifically limit such variations, and those skilled in the art can design them adaptively according to actual application needs.

[0034] It is understood that the specific embodiment in which the bottom end of the base 710 is slidably inserted into the groove 320 is exemplary. In other alternative embodiments not shown, the base 710 may also be fixed to the second clamping part 3. For example, the base 710 may be constructed as a plastic base and fixed to the second clamping part 3 by fasteners such as welding or bolts. In this way, when the operator operably pries the base 710, the deformation of the plastic base can achieve, for example, inserting the buckle 610 into the corresponding slot 712 and engaging with the spring buckle 713, or withdrawing the buckle 610, for example, located in the slot 712 and engaging with the spring buckle 713, out of the slot 712, thereby achieving the purpose of engaging and fixing or opening and unlocking the first clamping part 1. After the operator removes the external force, the base 710 can also return to its initial state.

[0035] In some possible implementations, refer to Figures 1 to 4As shown, the second clamping part 3 may include a housing 330, and the channel 310 includes a first cavity 311, a second cavity 312 and a third cavity 313 arranged sequentially in the housing 330 and connected in the first direction. The first end of the housing 330 has a first flared opening 314 connected to the first cavity 311. The inner diameter of the first flared opening 314 gradually decreases towards the side closer to the second cavity 312. Thus, the arrangement of the first flared opening 314 facilitates the smooth introduction of the guide wire 5 from the first flared opening 314 into the channel 310 of the second clamping part 3 in the first direction, thereby reducing the difficulty of feeding the guide wire 5 into the guide wire control device.

[0036] Additionally, in some possible implementations, refer to Figures 1 to 4 As shown, the end of the first cavity 311 near the second cavity 312 may have a second flared opening 315 communicating with the second cavity 312. The inner diameter of the second flared opening 315 gradually decreases toward the side away from the second cavity 312. This arrangement facilitates the smooth introduction of the guide wire 5 from the second flared opening 315 into the second cavity 312 and the third cavity 313 in, for example, a first direction. Since the inner diameter of the second flared opening 315 gradually decreases toward the side away from the second cavity 312, when the guide wire 5 is introduced into the channel 310 from, for example, the inlet / outlet 331 (described in detail below) at the second end of the housing 330, it also facilitates the smooth introduction of the guide wire 5 into the first cavity 311 via the second cavity 312, thereby improving the pushing effect of the guide wire 5 and reducing the operational difficulty of feeding the guide wire 5 into the guide wire control device.

[0037] The maximum inner diameter of the first flared opening 314 can be smaller than the maximum inner diameter of the second flared opening 315. This arrangement facilitates the smooth introduction of the guide wire 5 into the third cavity 313 along, for example, the first direction, or into the first cavity 311 along, for example, the first direction, thereby reducing the difficulty of feeding the guide wire 5 into the guide wire control device.

[0038] Additionally, in some possible implementations, refer to Figures 1 to 4 As shown, the end of the third cavity 313 near the second cavity 312 may have a third flared opening 316 communicating with the second cavity 312. The inner diameter of the third flared opening 316 gradually decreases toward the side away from the second cavity 312. This arrangement facilitates the smooth introduction of the guide wire 5 into the third cavity 313 from the third flared opening 316 along, for example, a first direction. In the case where, for example, the guide wire 5 is introduced into the channel 310 from the inlet / outlet 331 (described in detail below) at the second end of the housing 330, it also facilitates the smooth introduction of the guide wire 5 into the second cavity 312 and the first cavity 311 via the third cavity 313, thereby improving the pushing effect of the guide wire 5 and reducing the operational difficulty of feeding the guide wire 5 into the guide wire control device.

[0039] The maximum inner diameter of the third flared opening 316 can be no less than the maximum inner diameter of the second flared opening 315. This arrangement ensures that the guide wire 5 is smoothly introduced into the third cavity 313 along, for example, the first direction, or smoothly introduced into the first cavity 311 along, for example, the first direction, reducing the difficulty of feeding the guide wire 5 into the guide wire control device.

[0040] Additionally, in some possible implementations, refer to Figures 1 to 4 As shown, the third cavity 313 may have a fourth flared opening 317 on the side opposite to the second cavity 312. The fourth flared opening 317 is connected to the inlet and outlet 331 at the second end of the housing 330, and the inner diameter of the fourth flared opening 317 gradually decreases towards the side closer to the second cavity 312. With this arrangement, when the guide wire 5 is introduced into the channel 310 from the inlet and outlet 331 at the second end of the housing 330, it is easier to smoothly introduce the guide wire 5 into the third cavity 313, reducing the difficulty of feeding the guide wire 5 into the guide wire control device.

[0041] The maximum inner diameter of the third flared port 316 can be equal to the maximum inner diameter of the fourth flared port 317. This arrangement ensures that the guide wire 5 is smoothly introduced into the third cavity 313 along, for example, the first direction, reducing the difficulty of feeding the guide wire 5 into the guide wire control device.

[0042] It should be noted that this disclosure does not specifically limit the specific structural dimensions of the aforementioned channels 310 (e.g., the first cavity 311, the second cavity 312, and the third cavity 313). Those skilled in the art can adapt the design according to actual application requirements. For example, the specific structural dimensions of the channels 310 (e.g., the first cavity 311, the second cavity 312, and the third cavity 313) can be adapted to guidewires 5 of different sizes to ensure that guidewires 5 of different sizes can be inserted into the channels 310 of the second clamping part 3, so as to achieve operations such as advancing, pausing, retracting, and rotating guidewires 5 of different sizes by means of a guidewire control device, to meet, for example, guidewire intervention operations in blood vessels or guidewire retrieval operations in blood vessels.

[0043] Furthermore, this disclosure does not specifically limit the specific structure of the first clamping part 1 and the second clamping part 3 (outer shell 330). The purpose is to enable, for example, the formation of a first cavity 311, a second cavity 312 and a third cavity 313 arranged sequentially in a first direction within the outer shell 330. In a position such as the wire pushing position, the first wire feeding roller 2 and the second wire feeding roller 4 can be used to clamp the guide wire 5 located in the channel 310. This allows the guide wire 5 to be moved relative to the channel 310 by the rotation of the first wire feeding roller 2 and the second wire feeding roller 4, thereby achieving operations such as forward movement, pause, and retraction of the guide wire 5. The rotation of the guide wire 5 can also be achieved by operably rotating the first clamping part 1 and the second clamping part 3. Those skilled in the art can adaptably design the specific structure of the first clamping part 1 and the second clamping part 3 (outer shell 330) according to actual application requirements.

[0044] In some possible implementations, refer to Figure 1 and Figure 2 As shown, the second wire feeding roller 4 is located in the second cavity 312. In the second direction perpendicular to the first direction, the first cavity 311 and the third cavity 313 may both have a bottom point 318, and the second wire feeding roller 4 has a top point 430. The bottom point 318 and the top point 430 are arranged flush in the first direction. With this arrangement, when the guide wire 5 is smoothly passed through the channel 310 of the second clamping part 3 (for example, the first cavity 311, the second cavity 312 and the third cavity 313 are arranged in a connected manner), the risk of bending and deformation of the guide wire 5 can be reduced, which is beneficial to improving the guide wire pushing effect.

[0045] It should be noted that, for example, in the guidewire control device, for example... Figure 2 In the posture shown, the second direction can be understood as the height direction or the vertical direction. In this posture, the first roller 210 is located above the second roller 410 (that is, the first wire feeding roller 2 is located in the wire pushing position), and the first cavity 311 and the third cavity 313 can both have a bottom point 318, and the second wire feeding roller 4 has a top point 430.

[0046] In order to improve guidewire delivery efficiency, in some possible implementations, refer to Figures 1 to 4As shown, the first wire feeding roller 2 may include a first roller 210 and a first friction layer 220 disposed on the outer peripheral wall of the first roller 210. The second wire feeding roller 4 includes a second roller 410 and a second friction layer 420 disposed on the outer peripheral wall of the second roller 410. Thus, by providing the first friction layer 220 and the second friction layer 420, the first roller 210 can be tightly fitted to the guide wire 5 through the first friction layer 220, and the second roller 410 can be tightly fitted to the guide wire 5 through the second friction layer 420. This increases the contact friction, so that when the first wire feeding roller 2 is driven to rotate, for example by the thumb, the rotation of the first wire feeding roller 2 and the second wire feeding roller 4 can drive the guide wire 5 to move relative to the channel 310, which is beneficial to improving the guide wire pushing efficiency.

[0047] For example, refer to Figures 1 to 4 As shown, a first mounting groove for mounting a first roller 210 can be formed on the first clamping part 1, and the first roller 210 can be rotatably disposed in the first mounting groove via, for example, a first rotating shaft, so that the first roller 210 can be rotatably connected to the first clamping part 1. Additionally, a second mounting groove for mounting a second roller 410 can be formed in the second cavity 312 of the second clamping part 3, and the second roller 410 can be rotatably disposed in the second mounting groove via, for example, a second rotating shaft, so that the second roller 410 can be rotatably connected to the second clamping part 3. Thus, the rotation of the first wire feeding roller 2 and the second wire feeding roller 4 can drive the guidewire 5 to move relative to the channel 310, satisfying, for example, guidewire intervention operations within a blood vessel or guidewire retrieval operations within a blood vessel.

[0048] In some possible implementations, reference is made to Figures 1 to 4 As shown, the maximum outer diameter of the first roller 210 can be greater than the maximum outer diameter of the second roller 410. With this arrangement, using the first roller 210 with a larger outer diameter as the active drive wheel can ensure that the first roller 210, which is the active drive wheel, has a longer contact arc length with the guide wire 5. This not only reduces the risk of bending and deformation of the guide wire 5, but also helps to improve the guide wire pushing efficiency.

[0049] Additionally, in some possible implementations, refer to Figures 1 to 4 As shown, the maximum thickness of the first friction layer 220 can be greater than the maximum thickness of the second friction layer 420. With this arrangement, the guide wire 5 can be supported by the thinner second friction layer 420. This can reduce the possibility of the guide wire 5 being squeezed and deformed when, for example, the first wire feeding roller 2 and the second wire feeding roller 4 are clamped between the guide wire 5, which is beneficial to improving the guide wire pushing effect.

[0050] Exemplarily, the first friction layer 220 may be made of materials including, but not limited to, silicone rubber or medical polyurethane. Similarly, the second friction layer 420 may also be made of materials including, but not limited to, silicone rubber or medical polyurethane. This disclosure is not limited thereto.

[0051] In some possible implementations, refer to Figures 1 to 4 As shown, the guidewire control device may further include a handle 9 sleeved on the second clamping part 3. The handle 9 has a fourth cavity 910 that runs through the handle 9 in a first direction and communicates with the channel 310. The first clamping part 1 is located outside the handle 9. In the wire pushing position, the second clamping part 3 is configured to be able to rotate relative to the handle 9 by external force, so as to drive the guidewire 5 to rotate around its own central axis A by the first wire feeding roller 2 and the second wire feeding roller 4 clamped on the guidewire 5. Thus, the handle 9 is designed so that the operator can hold the handle 9 with one hand and can directly rotate the first clamping part 1 and the second clamping part 3 relative to the handle 9 by using, for example, the thumb and forefinger of the hand holding the handle 9. At the same time, the operator can also directly drive the first wire feeding roller 2 to rotate by using, for example, the thumb of the hand holding the handle 9. This makes it convenient for the operator to perform operations such as forward, pause, backward and rotation during the guidewire delivery process with one hand. The operation is more convenient and can effectively improve the safety and efficiency of guidewire interventional operations in blood vessels.

[0052] Additionally, refer to Figures 1 to 4 As shown, along the first direction, the second clamping part 3 and the first clamping part 1 can be located at the front end of the handle 9, so that when the operator holds the handle 9 with one hand, he can rotate the first clamping part 1 and the second clamping part 3 relative to the handle 9 by using, for example, the thumb and forefinger on the palm of the hand holding the handle 9, and drive the first wire feeding roller 2 to rotate by using, for example, the thumb on the palm of the hand holding the handle 9, so that the operator can easily complete operations such as forward, pause, backward and rotation during the wire feeding process with one hand.

[0053] Furthermore, this disclosure does not specifically limit the specific structural dimensions of the aforementioned fourth cavity 910. Those skilled in the art can design it adaptively according to actual application needs. For example, the specific structural dimensions of the fourth cavity 910 can be adaptively designed according to guidewires 5 of different specifications and sizes to ensure that guidewires 5 of different specifications and sizes can be inserted into the fourth cavity 910. This allows for operations such as advancing, pausing, retracting, and rotating guidewires 5 of different specifications and sizes to be achieved by means of a guidewire control device, thereby satisfying, for example, guidewire intervention operations in blood vessels or guidewire removal operations in blood vessels.

[0054] Additionally, it should be noted that, in cases where a guidewire control device is required to clamp guidewires 5 of different sizes, the operator can hold the handle 9 with one hand and use the other hand to guide the guidewire 5 from the first flared opening 314 into the channel 310 (e.g., the first cavity 311, the second cavity 312, and the third cavity 313) of the second clamping part 3 along, for example, the first direction, so that the guidewire 5 can be inserted into the second clamping part 3. In this way, after the guidewire 5 is sent into the preset position, the operator can directly use, for example, the thumb of the hand holding the handle 9 to directly rotate the first clamping part 1 to the position where the first wire feeding roller 2 and the second wire feeding roller 4 are clamped in the push position of the guidewire 5 located in the channel 310, and the first clamping part 1 can be locked in the second clamping part 3. The overall operation is more convenient and less difficult, which can effectively improve the safety and efficiency of guidewire interventional operations in blood vessels.

[0055] In order to ensure that the handle 9 is stably fitted onto the second clamping part 3 and to reduce the risk of the second clamping part 3 disengaging, for example, when the operator operably drives the second clamping part 3 to rotate relative to the handle 9, in some possible embodiments, reference is made to... Figures 1 to 4 As shown, a limiting structure 10 can be provided on the inner wall surface of the handle 9, and a limiting engagement structure 11 is provided on the outer wall surface of the second clamping part 3. The limiting structure 10 and the limiting engagement structure 11 cooperate to limit and fix the second clamping part 3, thereby reducing the risk of the second clamping part 3 coming off, for example, when the operator can operably drive the second clamping part 3 to rotate relative to the handle 9.

[0056] Those skilled in the art can adapt the specific structure of the limiting structure 10 and the limiting mating structure 11 according to the actual application requirements. For example, one of the limiting structure 10 and the limiting mating structure 11 may include, for example, a limiting groove, and the other includes a limiting protrusion that mates with the limiting groove. The purpose is to achieve the limiting and fixing of the second clamping part 3, so that the operator can operably drive the first clamping part 1 and the second clamping part 3 to rotate relative to the handle 9.

[0057] Furthermore, this disclosure does not specifically limit the structural dimensions of the first clamping part 1, the second clamping part 3, and the handle 9. The purpose is to facilitate the operator's handling and operation, so that the operator can easily complete operations such as forward movement, pause, backward movement, and rotation during the wire feeding process with one hand. Those skilled in the art can adapt the design according to actual application needs.

[0058] Furthermore, in order to facilitate the attachment of the handle 9 to the second clamping part 3, the handle 9 can be constructed to include a first housing and a second housing that are detachably connected. Thus, the arrangement of the first housing and the second housing facilitates the attachment of the handle 9 to the second clamping part 3. The first housing and the second housing can be detachably connected by a fixed connection method such as snap-fit ​​connection and / or threaded connection.

[0059] Based on the above embodiments, this disclosure exemplarily describes the usage process of the guidewire control device as follows: refer to Figures 1 to 4 As shown, for example, when a guidewire intervention operation within a blood vessel requires the assistance of a guidewire control device, the operator can hold the handle 9 with one hand, and use the thumb and forefinger of the hand holding the handle 9 to grip the first clamping part 1 and the second clamping part 3 to prevent rotation of the first clamping part 1 and the second clamping part 3. Using the other hand, the guidewire 5 to be implanted is introduced from the first flared opening 314 into the channel 310 (e.g., the first cavity 311, the second cavity 312, and the third cavity 313) of the second clamping part 3 along, for example, a first direction. During the insertion of the guidewire 5 into the channel 310, it can be positioned as close as possible to the first cavity 311. The guide wire 5 is fed into the bottom wall of the third cavity 313 (e.g., the bottom wall surface where the bottom point 318 is located). As the guide wire 5 passes through the first cavity 311, the second cavity 312 and the third cavity 313 in sequence and extends out from the inlet and outlet 331 at the second end of the outer shell 330, when the guide wire 5 is fed into the preset position, the operator can directly turn the first clamping part 1 by using the thumb of the hand holding the handle 9 to make the first wire feeding roller 2 and the second wire feeding roller 4 clamp the guide wire 5 in the corresponding wire pushing position in the channel 310, and make the first clamping part 1 lock into the second clamping part 3.

[0060] After the guidewire 5 to be implanted is installed in the guidewire control device, the operator can hold the handle 9 with one hand, as shown in the reference. Figure 2 As shown, the first wire feeding roller 2 is driven clockwise by, for example, the thumb of the hand holding the handle 9. Thus, the operator can drive the guide wire 5 forward with one hand. Figure 2 As shown, this can drive the guidewire 5 to move forward in, for example, a first direction (which can be understood as the guidewire 5 moving along...). Figure 2 The image direction moves forward from right to left, achieving the purpose of intravascular guidewire intervention with the aid of a guidewire control device. Furthermore, by driving the first feed roller 2 counterclockwise by, for example, the thumb on the hand holding the handle 9, the operator can drive the guidewire 5 backward with one hand. Figure 2 As shown, it can realize the drive guidewire 5 to move backward along, for example, the first direction (which can be understood as the guidewire 5 moving along...). Figure 2The image direction is backward movement from left to right. Additionally, by using, for example, the thumb and forefinger of the hand holding the handle 9, the first clamping part 1 and the second clamping part 3 can be rotated relative to the handle 9 (wherein, the direction of rotation of the first clamping part 1 and the second clamping part 3 relative to the handle 9 can be referenced). Figure 3 (As shown by the arrow in the image), the operator can rotate the guidewire 5 with one hand, that is, as... Figure 2 As shown, the guidewire 5 can be driven to rotate around its own central axis A. In this way, the guidewire control device can be used to realize the guidewire intervention operation in the blood vessel. Since the operator can complete the operation with one hand, the operation is more convenient and can effectively improve the safety and efficiency of the guidewire intervention operation in the blood vessel.

[0061] It should be noted that, in the specific embodiment where the guide wire 5 to be implanted is introduced into the channel 310 (e.g., the first cavity 311, the second cavity 312, and the third cavity 313) of the second clamping part 3 by the other hand along, for example, the first direction, when installing the guide wire 5 to be implanted into the guide wire control device, is exemplary. In some alternative embodiments, the guide wire 5 to be implanted can also be introduced into the channel 310 of the second clamping part 3 along, for example, the first direction, from the inlet / outlet 331 of the outer shell 330 located at the second end. For example, the guide wire 5 to be implanted can be first passed through the handle 9 via the fourth cavity 910 and then introduced into the channel 310 of the second clamping part 3 via the inlet / outlet 331. That is, the guide wire 5 can be sequentially passed through the third cavity 313, the second cavity 312, and the first cavity 311. This disclosure does not specifically limit such variations, and those skilled in the art can design them adaptively according to actual application needs.

[0062] When a guidewire retrieval operation within a blood vessel requires the assistance of a guidewire control device, the operator can hold the handle 9 with one hand, and use the thumb and forefinger of the hand holding the handle 9 to grip the first clamping part 1 and the second clamping part 3, preventing rotation of the first clamping part 1 and the second clamping part 3. Then, the guidewire 5 to be retrieved is introduced into the channel 310 (e.g., first cavity 311, second cavity 312, and third cavity 313) of the second clamping part 3 along, for example, a first direction from the first flared opening 314. During the process of feeding the guide wire 5 into the channel 310, it can be fed into the bottom wall of the first cavity 311 and the third cavity 313 (e.g., the bottom wall surface where the bottom point 318 is located) as close as possible. After the guide wire 5 is fed into the preset position, the operator can directly turn the first clamping part 1 by using the thumb of the hand holding the handle 9 to make the first wire feeding roller 2 and the second wire feeding roller 4 clamp the guide wire 5 in the corresponding pushing position in the channel 310, and make the first clamping part 1 lock into the second clamping part 3.

[0063] After the guidewire 5 to be removed is installed in the guidewire control device, the operator can hold the handle 9 with one hand, as shown in the reference. Figure 2 As shown, when the first wire feeding roller 2 is driven to rotate counterclockwise by, for example, the thumb on the palm holding the handle 9, the operator can drive the guidewire 5 to retract with one hand. In addition, by, for example, the thumb and forefinger on the palm holding the handle 9 to rotate the first clamping part 1 and the second clamping part 3 relative to the handle 9, the operator can drive the guidewire 5 to rotate with one hand. In this way, the guidewire retrieval operation in the blood vessel can be achieved with the help of the guidewire control device. Since the operator can complete the operation with one hand, the operation is more convenient and can effectively improve the safety and efficiency of the guidewire retrieval operation in the blood vessel.
