Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a guidewire delivery device. Background Technology

[0002] Minimally invasive surgery is a technique that involves surgical procedures through small incisions or natural cavities. Compared to traditional open surgery, it offers advantages such as less trauma, faster recovery, and less postoperative pain. Guidewires, as auxiliary tools in minimally invasive surgery, help surgeons accurately locate and guide surgical instruments and perform specific treatments. Guidewire intervention typically requires the use of a guidewire delivery device.

[0003] In related technologies, a guide wire delivery device includes a mounting platform, a first delivery component, a first servo motor, a second delivery component, and a second servo motor. The first delivery component, the first servo motor, the second delivery component, and the second servo motor are all mounted on the mounting platform. The first servo motor drives the first delivery component, and the second servo motor drives the second delivery component. The first delivery component includes a first clamping wheel and a second clamping wheel, which can clamp the guide wire. The first servo motor drives the first clamping wheel to rotate. The second clamping component includes a third clamping wheel and a fourth clamping wheel, which can clamp the guide wire. The second servo motor drives the third clamping wheel to rotate. When the first and second servo motors rotate, the first, second, third, and fourth clamping wheels rotate, and the guide wire is delivered.

[0004] However, since the delivery of the guidewire requires clamping by the first clamping wheel, the second clamping wheel, the third clamping wheel, and the fourth clamping wheel, if any of the clamping wheels is contaminated, the guidewire will also be contaminated, which will have an adverse effect on the subsequent minimally invasive surgery. Summary of the Invention

[0005] To reduce contamination of the guidewire during delivery, this application provides a guidewire delivery device.

[0006] The guidewire delivery device provided in this application adopts the following technical solution:

[0007] A guide wire delivery device includes a base with a mounting seat; four sets of drive wheels mounted on the mounting seat, wherein two sets of drive wheels are spaced apart along a first direction and their wheel surfaces face each other, and the other two sets of drive wheels are spaced apart along a second direction and their wheel surfaces face each other, the first and second directions being perpendicular to each other, and the guide wire is suspended in the gap formed by the four sets of drive wheels; each set of drive wheels has multiple drive wheels spaced apart along the axial direction of the guide wire, a synchronization component is provided between two adjacent drive wheels in each set to enable them to rotate synchronously, a reversing component is provided between two sets of drive wheels spaced apart along the first direction to reverse the direction of the two sets of drive wheels, and a reversing component is provided between two sets of drive wheels spaced apart along the second direction to reverse the direction of the two sets of drive wheels; two drive components are provided, each corresponding to one of the two reversing components, one side of the drive component is connected to the mounting seat, and the other side is connected to the reversing components to drive the drive wheels to rotate; multiple first magnetic blocks are evenly spaced along the circumference of the drive wheels, and multiple second magnetic blocks are evenly spaced along the axial direction on the side of the guide wire and the drive wheels facing each other, the first magnetic blocks and the second magnetic blocks repel each other.

[0008] By adopting the above technical solution, when the operator uses the guide wire delivery device to deliver the guide wire, the guide wire is inserted into the gap formed by the four sets of drive wheels. Under the repulsive force between the first magnetic block on the four sets of drive wheels and the second magnetic block on the guide wire, the guide wire is repelled in all four directions (up, down, left, and right), thus suspending the guide wire in the gap formed by the four sets of drive wheels. When the drive assembly is working, under the action of the synchronization component, all drive wheels rotate. At the same time, under the action of the reversing component, the two sets of drive wheels spaced apart along the first direction rotate in opposite directions, so that the linear velocity directions of the two sets of drive wheels spaced apart along the first direction are the same on the side closest to the guide wire. The motion principle of the two sets of drive wheels spaced apart along the second direction is the same. Since there is a repulsive force between the first magnetic block on the drive wheel and the second magnetic block on the guide wire, when the drive wheel rotates, the first magnetic block on the drive wheel will generate a linear velocity in the axial direction of the guide wire, which will push the guide wire to move, thereby completing the delivery of the guide wire. During guidewire delivery, the guidewire remains suspended and does not come into contact with the drive wheel, thus avoiding contamination of the drive wheel and reducing contamination of the guidewire during delivery.

[0009] Optionally, the drive wheel includes a rotating rod and a wheel body, the rotating rod is rotatably mounted on the mounting base, and the wheel body is coaxially fixed to the rotating rod; the synchronization assembly includes a belt and two pulleys, the two ends of the belt are respectively sleeved on the two pulleys, and the two pulleys are coaxially fixed to two adjacent rotating rods in the same group.

[0010] By adopting the above technical solution, when one of the rotating rods rotates, the pulley on the rotating rod rotates synchronously, and then drives the other pulley to rotate in the same direction through the belt, thereby realizing that the two adjacent rotating rods rotate synchronously in the same direction. A synchronization component is set between each pair of adjacent drive wheels to ensure the consistency of the rotation of all wheels in the same group, so that the linear velocity of the first magnetic block in the same group is in the same direction, and the driving force on the guide wire is in the same direction, thus realizing the stable delivery of the guide wire.

[0011] Optionally, the drive wheel includes a rotating rod and a wheel body, the rotating rod is rotatably mounted on the mounting base, and the wheel body is coaxially fixed to the rotating rod; the synchronization assembly includes a reversing wheel and two synchronization gears, the two synchronization gears are coaxially fixed to two adjacent rotating rods in the same group, the reversing wheel is rotatably mounted on the mounting base and meshes with the two synchronization gears respectively.

[0012] By adopting the above technical solution, when one of the rotating rods rotates, it drives the synchronous gear on it to rotate. After the synchronous gear rotates, it drives the reversing wheel to rotate in the opposite direction. Then, the reversing wheel drives the other synchronous gear to rotate, and the two rotate in opposite directions. Therefore, the two synchronous gears rotate in the same direction, ultimately achieving the same rotation direction for two adjacent rotating rods. A synchronization component is set between every two adjacent drive wheels to ensure the consistency of rotation of all wheels in the same group, thereby achieving stable delivery of the guide wire.

[0013] Optionally, the reversing assembly includes two meshing drive gears, which correspond to two sets of drive wheels spaced apart along a first direction, or the two drive gears correspond to two sets of drive wheels spaced apart along a second direction, with one drive gear coaxially fixed to a rotating rod of one set and the other drive gear coaxially fixed to a rotating rod of the other set.

[0014] By adopting the above technical solution, when one of the rotating rods drives the drive gear on it to rotate, the drive gear drives the other drive gear to rotate in the opposite direction, thereby causing the two rotating rods to rotate in opposite directions.

[0015] Optionally, the reversing assembly includes a reversing belt and two drive pulleys. The two drive pulleys correspond to two sets of drive wheels spaced apart along a first direction, or the two drive gears correspond to two sets of drive wheels spaced apart along a second direction. One drive pulley is coaxially fixed to a rotating rod in one set, and the other drive pulley is coaxially fixed to a rotating rod in the other set. One end of the reversing belt is sleeved on one of the drive pulleys, and the other end is rotated 180° and then sleeved on the other drive pulley.

[0016] By adopting the above technical solution, when one of the drive pulleys rotates, it drives the other drive pulley to rotate via the reverse belt. Since the reverse belt is twisted 180°, the two drive pulleys rotate in opposite directions, thereby causing the two sets of drive wheels spaced apart along the first direction to rotate in opposite directions, or the two sets of drive wheels spaced apart along the second direction to rotate in opposite directions, so that the linear velocity directions of the first magnetic blocks on opposite sides of the guide wire are the same.

[0017] Optionally, one of the rotating rods extends out of the mounting base, and the drive assembly includes a drive motor and a transmission component. The drive motor is fixed to the mounting base, one end of the transmission component is connected to the output end of the drive motor, and the other end is connected to the rotating rod extending out of the mounting base.

[0018] By adopting the above technical solution, when the output end of the motor rotates, the transmission component transmits the power of the motor to the rotating rod, thereby driving the rotating rod to rotate. The rotating rod drives another rotating rod to rotate through the reverse component.

[0019] Optionally, the transmission component includes a transmission belt and two power transmission pulleys, one of which is fixed to the output end of the drive motor, and the other is coaxially fixed to the rotating rod extending from the mounting base. The two ends of the transmission belt are respectively sleeved on the two power transmission pulleys.

[0020] By adopting the above technical solution, when the output end of the drive motor rotates, the power transmission wheel fixed on it rotates, and through the transmission belt, another power transmission wheel rotates, thereby driving the rotating rod to rotate.

[0021] Optionally, the wheel body has a plurality of first mounting holes for accommodating the first magnet evenly spaced along its circumference on its wheel surface; a second mounting hole is provided between every two adjacent first mounting holes, and the second mounting hole is located on the side of the wheel body.

[0022] By adopting the above technical solution, since the magnetic blocks are purchased standard parts, if both the first mounting holes and the second mounting holes are spaced apart along the wheel surface, when the diameter of the wheel is to be further reduced, the two adjacent first magnetic blocks will interfere. With the arrangement of this embodiment, instead of having both the first and second mounting holes located on the wheel surface, the diameter of the wheel can be further reduced, thereby reducing the overall size of the guide wire delivery device.

[0023] Optionally, the mounting base includes a first body, a second body, a third body, and a fourth body, which together form a cavity for accommodating the wheel. The first body and the second body are fixed to each other, the second body and the third body are fixed to each other, the third body and the fourth body are fixed to each other, and the fourth body and the first body are fixed to each other. The two ends of the first set of drive wheels are respectively mounted on the first body and the fourth body, the two ends of the second set of drive wheels are respectively mounted on the second body and the third body, the two ends of the third set of drive wheels are respectively mounted on the first body and the second body, and the two ends of the fourth drive wheel are respectively mounted on the third body and the fourth body.

[0024] By adopting the above technical solution, the separate mounting base makes it easier to install the four sets of drive wheels. In addition, when the synchronization component uses a belt and pulley, the belt tension can be adjusted by placing shims between two adjacent bodies, thereby ensuring the good operation of the synchronization component.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] When the guide wire delivery device is used to deliver the guide wire, the guide wire is inserted into the gap formed by four sets of drive wheels. Under the repulsive force between the first magnetic block on the four drive wheels and the second magnetic block on the guide wire, the guide wire is repelled in all four directions (up, down, left, and right), thus suspending the guide wire within the gap. When the drive assembly is activated, all drive wheels rotate under the action of the synchronization component. Simultaneously, under the action of the reversing component, the two sets of drive wheels spaced apart along the first direction rotate in opposite directions, resulting in the same linear velocity direction on the side of the two sets of drive wheels spaced apart along the first direction closest to the guide wire. The motion principle of the two sets of drive wheels spaced apart along the second direction is similar. Because there is a repulsive force between the first magnetic block on the drive wheel and the second magnetic block on the guide wire, when the drive wheel rotates, the first magnetic block on the drive wheel generates a linear velocity in the axial direction of the guide wire, pushing the guide wire to move, thereby completing the delivery of the guide wire. During guidewire delivery, the guidewire remains suspended and does not come into contact with the drive wheel, thus avoiding contamination of the drive wheel and reducing contamination of the guidewire during delivery.

[0038] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0039] This application discloses a guidewire delivery device. Combined with... Figure 1 and Figure 2 The guide wire delivery device includes a base 1, four sets of drive wheels 2, and two drive assemblies 3. The base 1 is provided with a mounting seat 11, and the four sets of drive wheels 2 are mounted on the mounting seat 11. Two sets of drive wheels 2 are spaced apart along a first direction with their wheel surfaces facing each other, and the other two sets of drive wheels 2 are spaced apart along a second direction with their wheel surfaces facing each other. The first and second directions are perpendicular to each other, and the guide wire is suspended in the gap formed by the four sets of drive wheels 2. Each set of drive wheels 2 has multiple wheels spaced apart along the axial direction of the guide wire. A synchronizing assembly 4 is provided between two adjacent drive wheels 2 within each set to enable them to rotate synchronously. A reversing assembly 5 is provided between two sets of drive wheels 2 spaced apart along the first direction to reverse their rotation direction, and between two sets of drive wheels 2 spaced apart along the second direction to reverse their rotation direction. The two drive assemblies 3 correspond to the two reversing assemblies 5, with one side of each drive assembly 3 connected to the mounting seat 11 and the other side connected to the reversing assembly 5, for driving the drive wheels 2 to rotate. The drive wheel 2 is provided with a plurality of first magnetic blocks 6 evenly spaced along its circumference, and the guide wire and the drive wheel 2 are provided with a plurality of second magnetic blocks 7 evenly spaced along their axial direction. The first magnetic blocks 6 and the second magnetic blocks 7 repel each other.

[0040] Specifically, in the embodiments of this application, the first direction is preferably horizontal, and the second direction is preferably vertical. In other embodiments, the first direction may deviate from the horizontal direction, and the second direction may deviate from the vertical direction, but the first and second directions are guaranteed to be perpendicular. In addition, in the preferred embodiment of this application, each group of drive wheels 2 is preferably provided with three drive wheels 2. In other embodiments, each group of drive wheels 2 may be provided with four, five or more groups, thereby ensuring the stability of guide wire delivery.

[0041] Furthermore, in combination Figure 1 and Figure 2 The drive wheel 2 includes a rotating rod 21 and a wheel body 22. The rotating rod 21 is rotatably mounted on the mounting base 11, and the wheel body 22 is coaxially fixed to the rotating rod 21. In this embodiment, the two are integrally formed. In other embodiments, the wheel body 22 may also be bonded to the rotating rod 21. The synchronization assembly 4 includes a belt 41 and two pulleys 42. The two ends of the belt 41 are respectively sleeved on the two pulleys 42, and the two pulleys 42 are coaxially fixed to two adjacent rotating rods 21 in the same group.

[0042] When one of the rotating rods 21 rotates, the pulley 42 on the rotating rod 21 rotates synchronously, and then drives the other pulley 42 to rotate in the same direction through the belt 41, thereby realizing that the two adjacent rotating rods 21 rotate synchronously in the same direction. A synchronization component 4 is set between each pair of adjacent drive wheels 2, thereby ensuring the consistency of rotation of all wheels 22 in the same group, so that the linear velocity of the first magnetic block 6 in the same group is in the same direction, and the driving force on the guide wire is in the same direction, thus realizing the stable delivery of the guide wire.

[0043] In addition to the methods mentioned above, combined with Figure 1 and Figure 3 The synchronization component 4 may also include a reversing wheel 43 and two synchronization gears 44. The two synchronization gears 44 are coaxially fixed to two adjacent rotating rods 21 in the same group. The reversing wheel 43 is rotatably mounted on the mounting base 11 and meshes with the two synchronization gears 44 respectively. With this arrangement, when one of the rotating rods 21 rotates, it drives the synchronization gear 44 on it to rotate. After the synchronization gear 44 rotates, it drives the reversing wheel 43 to rotate in the opposite direction. Then, the reversing wheel 43 drives the other synchronization gear 44 to rotate in opposite directions. Therefore, the two synchronization gears 44 rotate in the same direction, ultimately achieving the same rotation direction for the two adjacent rotating rods 21. A synchronization component 4 is provided between every two adjacent drive wheels 2, thereby ensuring the consistency of rotation of all wheels 22 in the same group and achieving stable delivery of the guide wire.

[0044] Furthermore, in combination Figure 1 and Figure 2In a preferred embodiment of this application, the reversing component 5 may include a reversing belt 51 and two drive pulleys 52. For the two reversing components 5 in this embodiment, the two drive pulleys 52 in one reversing component 5 correspond to two sets of drive wheels 2 spaced apart along a first direction (spaced apart horizontally in this embodiment), and the two drive pulleys 52 in the other reversing component 5 correspond to two sets of drive wheels 2 spaced apart along a second direction (spaced apart vertically in this embodiment). Since a synchronization component 4 is provided between adjacent drive wheels 2 within the same set, when one drive wheel 2 in the same set rotates, the other drive wheels 2 rotate synchronously. Therefore, one drive pulley 52 is coaxially fixed to a rotating rod 21 in one set, and the other drive pulley 52 is coaxially fixed to a rotating rod 21 in another set. One end of the reversing belt 51 is sleeved on one drive pulley 52, and the other end is rotated 180° and then sleeved on the other drive pulley 52.

[0045] When one of the drive pulleys 52 rotates, it drives the other drive pulley 52 to rotate via the reverse belt 51. Since the reverse belt 51 is twisted 180°, the two drive pulleys 52 rotate in opposite directions, which makes the two sets of drive wheels 2 spaced apart along the first direction rotate in opposite directions, or the two sets of drive wheels 2 spaced apart along the second direction rotate in opposite directions, so that the linear velocity directions of the first magnetic blocks 6 on opposite sides of the guide wire are the same.

[0046] For the reverse component 5, in addition to the above-described embodiments, in other embodiments, combined with Figure 1 and Figure 3 The reversing component 5 also includes two meshing drive gears 53. In one reversing component 5, the two drive gears 53 correspond to two sets of drive wheels 2 spaced apart along a first direction (spaced apart horizontally in this embodiment). In the other reversing component 5, the two drive gears 53 correspond to two sets of drive wheels 2 spaced apart along a second direction (spaced apart vertically in this embodiment). One drive gear 53 is coaxially fixed to a rotating rod 21 of one set, and the other drive gear 53 is coaxially fixed to a rotating rod 21 of the other set. When one rotating rod 21 drives its drive gear 53 to rotate, that drive gear 53 drives the other drive gear 53 to rotate in the opposite direction, thus causing the two rotating rods 21 to rotate in opposite directions.

[0047] Furthermore, in combination Figure 1 and Figure 2The drive assembly 3 includes a drive motor 31 and a transmission component 32. A motor mount is fixed on the mounting base 11, and the drive motor 31 is fixed to the mounting base 11 via the motor mount. One of the rotating rods 21 extends out of the mounting base 11. One end of the transmission component 32 is connected to the output end of the drive motor 31, and the other end is connected to the rotating rod 21 extending out of the mounting base 11. When the output end of the motor rotates, the transmission component 32 transmits the power of the motor to the rotating rod 21, thereby driving the rotating rod 21 to rotate. The rotating rod 21 drives the other rotating rod 21 to rotate via the reversing assembly 5.

[0048] Furthermore, refer to Figure 2 The transmission component 32 includes a transmission belt 321 and two power transmission wheels 322. One power transmission wheel 322 is fixed to the output end of the drive motor 31, and the other power transmission wheel 322 is coaxially fixed to the rotating rod 21 extending from the mounting base 11. The two ends of the transmission belt 321 are respectively sleeved on the two power transmission wheels 322. Taking two sets of drive wheels 2 spaced apart along the first direction as an example, when the output end of the drive motor 31 rotates, the power transmission wheel 322 fixed on it rotates. Through the transmission belt 321, the other power transmission wheel 322 rotates, thereby driving the rotating rod 21 to rotate.

[0049] In other embodiments, the transmission component 32 may also consist of two transmission gears, one of which is fixed to the output end of the drive motor 31, and the other is coaxially fixed to the rotating rod 21. When the output end of the drive motor 31 drives one of the transmission gears to rotate, it drives the other transmission gear to rotate, thereby driving the rotating rod 21 to rotate.

[0050] Furthermore, in combination Figure 1 and Figure 4 The wheel body 22 has a plurality of first mounting holes 221 evenly spaced along its circumference for accommodating the first magnetic blocks 6. A second mounting hole 222 is provided between every two adjacent first mounting holes 221, and the second mounting hole 222 is located on the side of the wheel body 22. Since the first magnetic blocks 6 within the first mounting holes 221 are directly exposed, they can directly generate a repulsive force with the second magnetic blocks 7. The first magnetic blocks 6 within the second mounting holes 222 can generate a repulsive force with the second magnetic blocks 7 through the wheel surface of the drive wheel 2. Since the magnetic blocks are standard purchased parts, if both the first mounting holes 221 and the second mounting holes 222 are spaced along the wheel surface of the wheel body 22, when the diameter of the wheel body 22 is to be further reduced, adjacent first magnetic blocks 6 will interfere. Through the arrangement of this embodiment, compared to having both the first mounting holes 221 and the second mounting holes 222 located on the wheel surface, the diameter of the wheel body 22 can be further reduced, thereby reducing the overall size of the guide wire delivery device.

[0051] Furthermore, refer to Figure 1The mounting base 11 includes a first body 111, a second body 112, a third body 113, and a fourth body 114, which together form a cavity to accommodate the wheel body 22. The first body 111 and the second body 112 are fixed to each other, the second body 112 and the third body 113 are fixed to each other, the third body 113 and the fourth body 114 are fixed to each other, and the fourth body 114 and the first body 111 are fixed to each other. The two ends of the first set of drive wheels 2 are respectively mounted on the first body 111 and the fourth body 114, the two ends of the second set of drive wheels 2 are respectively mounted on the second body 112 and the third body 113, the two ends of the third set of drive wheels 2 are respectively mounted on the first body 111 and the second body 112, and the two ends of the fourth drive wheel 2 are respectively mounted on the third body 113 and the fourth body 114. With this configuration, the installation of the four sets of drive wheels 2 is more convenient due to the separate mounting base 11. In addition, when the synchronization component 4 uses a belt 41 and pulley 42, the tension of the belt 41 can be adjusted by placing shims between two adjacent bodies, thereby ensuring the good operation of the synchronization component 4.

[0052] The implementation principle of the guide wire delivery device in this application embodiment is as follows: When the operator uses the guide wire delivery device to deliver the guide wire, the guide wire is inserted into the gap formed by four sets of drive wheels 2. Under the repulsive force between the first magnetic block 6 on the four sets of drive wheels 2 and the second magnetic block 7 on the guide wire, the guide wire is repelled in all four directions (up, down, left, and right), thus suspending the guide wire in the gap formed by the four sets of drive wheels 2. When the drive assembly 3 is working, under the action of the synchronization assembly 4, all drive wheels 2 rotate. At the same time, under the action of the reversing assembly 5, the two sets of drive wheels 2 spaced apart along the first direction rotate in opposite directions, so that the linear velocity directions of the two sets of drive wheels 2 spaced apart along the first direction are the same on the side closer to the guide wire. The movement principle of the two sets of drive wheels 2 spaced apart along the second direction is the same. Since there is a repulsive force between the first magnetic block 6 on the drive wheel 2 and the second magnetic block 7 on the guide wire, when the drive wheel 2 rotates, the first magnetic block 6 on the drive wheel 2 will generate a linear velocity in the axial direction of the guide wire, which will push the guide wire to move, thereby completing the delivery of the guide wire. During the guidewire delivery process, the guidewire is in a suspended state and does not come into contact with the drive wheel 2, thus avoiding contamination of the drive wheel 2 and reducing contamination of the guidewire during delivery.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
