Description

Technical Field

[0001] This application generally relates to the field of medical device technology. More specifically, this application relates to a shaping device. Background Technology

[0002] In interventional procedures (such as cerebral aneurysm embolization), microcatheters need to be pre-shaped according to the three-dimensional anatomy of the patient's blood vessels to ensure that the microcatheter can smoothly reach the target lesion. Typically, the operator uses a metal wire as a shaping mold, bends the wire into a pre-set shape using a shaping device, and then places the microcatheter onto the shaped wire for heat setting, so that the tip of the microcatheter forms a curvature that matches the shape of the blood vessel.

[0003] Existing shaping equipment includes an integrated shaper, a frame, a shaping finger drive mechanism, and a twisting mechanism. This equipment uses the twisting mechanism (including a rotating disc, a second drive motor, a linear lifting module, and a first clamping assembly) to drive the piston assembly and the metal wire to rotate and feed synchronously. Simultaneously, the shaping finger drive mechanism drives the shaping fingers to slide back and forth, completing the multi-angle bending and shaping of the metal wire within a closed shaping cavity.

[0004] While the solution can shape the metal wire, it requires an independent twisting and feeding mechanism to achieve the rotation and linear feeding of the metal wire. This mechanism includes multiple components such as a rotating disk, a second drive motor, a linear lifting module, and a first clamping assembly, resulting in a bulky overall structure and large space occupation, making it difficult to adapt to compact application scenarios such as operating rooms.

[0005] Therefore, there is an urgent need for a metal wire shaping device with a simpler structure, easier operation, and lower cost, which can achieve three-dimensional bending of metal wires without relying on complex twisting mechanisms, while simplifying wire loading and unloading operations and improving the convenience of clinical use.

[0025] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-3 , Figure 6 As shown, in some embodiments, this application provides a shaping device 100, including: a frame; a mounting plate 10, which is vertically disposed on the frame; a wire feeding mechanism 12 is fixedly connected to a first side of the mounting plate 10; a wire outlet 27, which is fixedly disposed on the mounting plate 10 or the wire feeding mechanism 12; a support plate 28, which is disposed on the side of the mounting plate 10 opposite to the wire feeding mechanism 12, and has a through hole in its middle for avoiding the wire outlet 27; a shaping component 31 for bending and shaping the metal wire extending from the wire outlet 27 is provided on the side of the support plate 28 opposite to the mounting plate 10; and a driving component 40, which is pulsatorically connected to the mounting plate 10 or the support plate 28; the driving component 40 is used to drive the mounting plate 10 to rotate, so as to drive the metal wire to rotate about its axial direction, or to drive the support plate 28 to rotate, so as to drive the shaping component 31 to rotate.

[0027] In this application, the shaping equipment 100 includes a frame, a mounting plate 10, a wire outlet nozzle 27, a support plate 28, and a drive assembly 40. Specifically, the mounting plate 10 is vertically mounted on the frame, and a wire feeding mechanism 12 is fixedly connected to the first side of the mounting plate 10. The wire feeding mechanism 12 is used to continuously feed metal wire to the shaping station. The wire outlet nozzle 27 is fixedly mounted on the mounting plate 10 or the wire feeding mechanism 12, and is used to guide and position the metal wire fed by the wire feeding mechanism 12, so that the metal wire extends out in a defined spatial posture.

[0028] The support plate 28 is disposed on the side of the mounting plate 10 opposite to the wire feeding mechanism 12, i.e., the second side of the mounting plate 10. A through hole is provided in the middle of the support plate 28 to allow the wire exit nozzle 27 to pass through the support plate 28 and extend to the side opposite to the support plate 28, thereby achieving continuous wire feeding without interference with the support plate 28. A shaping assembly 31 is provided on the side of the support plate 28 opposite to the mounting plate 10. This shaping assembly 31 is used to bend and shape the wire extending from the wire exit nozzle 27. The shaping assembly 31 includes a pointer 32, a pointer mounting plate 33, and a pointer driving structure. The pointer driving structure drives the pointer 32 to press against the wire, causing plastic deformation of the wire.

[0029] The drive assembly 40 is connected to the mounting plate 10 or the carrier plate 28, and has two selectable drive modes. For example... Figure 1-3 As shown, in the first driving mode, the driving component 40 drives the support plate 28 to rotate, and the support plate 28 drives the shaping component 31 set on it to rotate synchronously. At this time, the metal wire remains axially fixed, and the shaping component 31 changes the force angle around the metal wire to form a disc-type shaping method.

[0030] like Figure 6 As shown, in the second driving mode, the driving component 40 drives the mounting plate 10 to rotate. The mounting plate 10 drives the wire feeding mechanism 12 fixed on its first side and the metal wire passing through the wire outlet 27 to rotate synchronously. At this time, the metal wire rotates around its own axis, while the shaping component 31 remains stationary, forming a wire rotation shaping method.

[0031] Those skilled in the art will understand that, in one embodiment, when only the mounting plate 10 rotates, the mounting plate 10 is configured as a circular plate structure, and the support plate 28 is fixedly connected to or integrally formed with the frame. In another embodiment, when only the support plate 28 rotates, the support plate 28 is configured as a circular plate structure, and the mounting plate 10 is fixedly connected to or integrally formed with the frame.

[0032] It is worth noting that the frame in this application is not limited to a traditional frame structure. In different embodiments, the frame can take various specific forms, such as a separate plate-like component, or a base portion integrally formed with the mounting plate 10 and having a predetermined thickness. As long as the requirement of fixing the mounting plate 10 or the bearing plate 28 in the vertical direction can be met, any form of support structure can be regarded as the frame described in this application.

[0033] This application does not require a dedicated twisting mechanism, piston assembly, and sealing housing. The bending direction can be changed simply by rotating the mounting plate 10 or the bearing plate 28. Combined with the wire feeding mechanism 12 and the shaping assembly 31, the metal wire can be three-dimensionally shaped. The structure is simple and compact, easy to operate, and the manufacturing cost is significantly reduced.

[0034] The above briefly describes how the drive assembly drives the mounting plate 10 or the carrier plate 28 to rotate in order to change the bending direction of the metal wire. The following describes in detail the specific implementation scheme of the drive assembly driving the carrier plate and the shaping assembly thereon to rotate.

[0035] like Figure 1-3 As shown, in a specific embodiment, the support plate 28 is a turntable, and a conveyor belt is provided on the outer periphery of the turntable. The conveyor belt is connected to the pulley 42 and tensioning wheel 41 of the drive assembly 40. The drive assembly 40 is mounted on the mounting plate 10 and is used to drive the turntable to rotate.

[0036] In this application, the mounting plate 10 is integrally formed with the frame and remains stationary, while the support plate 28 is a turntable. A conveyor belt is provided on the outer periphery of the turntable, and this conveyor belt is connected to the drive assembly 40 for transmission. Specifically, the drive assembly 40 is mounted on the mounting plate 10, and its output end is connected to a pulley 42, while a tensioning wheel 41 is configured to adjust the tension of the conveyor belt. The conveyor belt passes around the outer periphery of the turntable and forms a closed transmission circuit with the pulley 42 and the tensioning wheel 41.

[0037] When the drive assembly 40 is working, the pulley 42 rotates, driving the turntable to rotate around its own axis via the conveyor belt. This arrangement allows the drive assembly 40 to remain stationary with the mounting plate 10, while the turntable and its shaping assembly 31 can obtain stable rotational drive, which is beneficial for achieving multi-angle bending and shaping of the metal wire.

[0038] The above scheme details the rotation of the support plate 28 equipped with the shaping component 31. In other embodiments, when the mounting plate 10 equipped with the wire feeding mechanism 12 rotates, the support plate 28 can be fixed, and the mounting plate 10 can be a circular plate structure with a conveyor belt on its outer periphery, which is connected to the pulley of the drive component. Furthermore, other related structures can be adjusted as needed. In this configuration, the wire feeding mechanism 12 clamps the metal wire, and the mounting plate 10 drives the wire feeding mechanism 12 to rotate, thereby achieving axial rotation of the metal wire.

[0039] like Figure 3As shown, in a specific embodiment, an outer bearing 43 and an inner bearing 46 are provided between the mounting plate 10 and the support plate 28; the outer bearing 43 includes a body portion 44 and a connecting portion 45, the connecting portion 45 abutting against the outer periphery of the inner bearing 46; a limiting groove 11 is provided on the side of the mounting plate 10 near the support plate 28, the peripheral wall and bottom wall of the limiting groove abutting against the body portion 44 and providing radial and axial limiting respectively; an annular first boss 29 and a second boss 30 are provided on the side of the support plate 28 near the mounting plate 10, the first boss 29 providing axial limiting for the inner bearing 46, and the second boss 30 providing radial limiting for the inner bearing 46.

[0040] In this application, an outer bearing 43 and an inner bearing 46 are provided between the mounting plate 10 and the support plate 28. The outer bearing 43 includes a body portion 44 and a connecting portion 45. The thickness of the body portion 44 is greater than the thickness of the connecting portion 45, and the connecting portion 45 abuts against the outer periphery of the inner bearing 46. The thickness direction of the outer bearing 43 is parallel to the extension direction of the metal wire.

[0041] A limiting groove 11 is provided on the side of the mounting plate 10 near the support plate 28. The peripheral wall of the limiting groove 11 abuts against the outer peripheral wall of the body part 44 for radial limiting, and the bottom wall of the limiting groove 11 abuts against the side wall of the body part 44 for axial limiting. An annular first boss 29 and a second boss 30 are provided on the side of the support plate 28 near the mounting plate 10. The protrusion height of the second boss 30 is greater than that of the first boss 29. The inner peripheral wall of the inner bearing 46 away from the connecting part 45 abuts against the side wall of the second boss 30, thereby radially limiting the inner bearing 46. The side wall of the inner bearing 46 abuts against the top wall of the first boss 29, thereby axially limiting the inner bearing 46.

[0042] In this design, the mounting plate 10 and the support plate 28, through the cooperation of the aforementioned inner and outer bearings, ensure smooth relative rotation and good coaxiality. Simultaneously, the protrusions and bosses provide radial restraint for the outer bearing 43 and inner bearing 46, respectively, thereby improving the stability and rotational accuracy of the bearing installation. Furthermore, by arranging the outer bearing 43 and inner bearing 46 radially as support rings, rather than setting a central rotating shaft, the central area of ​​the support plate 28 is hollowed out, forming a through hole to avoid the thread outlet 27. This hollow rotating structure ensures smooth rotation of the support plate 28 relative to the mounting plate 10 while allowing the thread outlet 27 and the metal wire to pass unobstructed through the center, avoiding the interference problems associated with traditional central shaft designs. Moreover, since a central shaft is unnecessary, the axial distance between the mounting plate 10 and the support plate 28 is significantly reduced, thereby decreasing the overall length of the forming mechanism in the wire extension direction, making the equipment structure more compact. This also helps to shorten the suspended stroke of the metal wire, further improving the stability and accuracy of bending and forming.

[0043] like Figure 1 As shown, in one specific embodiment, a circular through hole is provided at the center of the mounting plate 10, and a circular adjusting plate 54 is fixedly installed on the second side of the mounting plate 10. The circular adjusting plate 54 has a through hole in the middle for the threaded nozzle 27 to pass through, and the outer diameter of the circular adjusting plate 54 is larger than the diameter of the circular through hole, but smaller than the inner diameter of the inner bearing 46.

[0044] like Figure 1 , Figure 3 and Figure 4 As shown, in one specific embodiment, the wire feeding mechanism 12 is fixed to the first side of the mounting plate 10 by a mounting block. It includes an upper roller 13 and a lower roller 14 disposed opposite each other, which are used to clamp and feed the metal wire to the second side of the mounting plate 10. The mounting block includes an upper mounting block 15 and a lower mounting block 16. Both mounting blocks have a fixing part 17 fixedly connected to the mounting plate 10, and a clamping part 18 extending from the fixing part 17 away from the mounting plate 10 and clamping both sides of the roller. The clamping part 18 is provided with a mounting hole coinciding with the central axis of the roller.

[0045] In this application, the wire feeding mechanism 12 is fixed to the first side of the mounting plate 10 by a mounting block, and is used to clamp and feed the metal wire to the second side of the mounting plate 10. The wire feeding mechanism 12 includes an upper roller 13 and a lower roller 14 arranged opposite to each other, wherein the lower roller 14 is the driving roller and is connected to a drive motor 56 through a small synchronous pulley 55. To prevent the metal wire from shifting laterally or slipping during feeding, the upper roller 13 and the lower roller 14 are respectively provided with annular grooves on their circumferential surfaces to accommodate and position the metal wire.

[0046] The mounting block further includes an upper mounting block 15 and a lower mounting block 16, both of which have a fixing part 17 and a clamping part 18. The fixing part 17 is mounted on the mounting plate 10 by fasteners; in this embodiment, since a circular adjusting plate 54 is fixedly mounted on the mounting plate 10, the fixing part 17 is mounted on the mounting plate 10 by fixing it to the adjusting plate 54. The clamping part 18 extends from the fixing part 17 in a direction away from the mounting plate 10, clamping both sides of the upper roller 13 or the lower roller 14 respectively. Each clamping part 18 has a mounting hole, the position of which coincides with the central axis of the corresponding roller, for mounting the shaft end of the roller, and the shaft end can be fitted with a bearing to improve the smoothness of rotation.

[0047] The solution of this application uses the upper roller 13 and the lower roller 14 to rotate continuously under the drive of the drive motor. The metal wire is clamped and pushed by friction, which can realize the continuous and controllable feeding of the metal wire, instead of being able to feed intermittently at only one end at a time like the piston assembly. This is beneficial to improving the shaping efficiency and the flexibility of the wire feeding length.

[0048] like Figure 1 As shown, in one specific embodiment, the fixing portion 17 of the upper mounting block 15 has two spaced-apart U-shaped grooves 19, the openings of which face away from the lower mounting block 16. A limiting component 20 and a connector 21 extending perpendicularly to the mounting plate 10 are respectively installed in the two U-shaped grooves 19.

[0049] like Figure 4 As shown, the wire feeding mechanism 12 also includes a connecting plate 22, which is fixedly connected to the two clamping portions 18 of the upper mounting block 15 and the two clamping portions 18 of the lower mounting block 16, thereby forming an integrated frame structure between the upper mounting block 15 and the lower mounting block 16, improving the overall rigidity. A pressure plate 23 is also provided on the outer side of the connecting plate 22 corresponding to the lower mounting block 16. This pressure plate 23 is used to enhance the connection strength between the lower mounting block 16 and the connecting plate 22, preventing loosening under stress.

[0050] The connecting plate 22 is also provided with two extension holes 24 extending along the height direction of the molding mechanism. The connecting plate 22 corresponding to the upper mounting block 15 is equipped with a consumable mounting part 25. Fasteners pass through the mounting holes of the consumable mounting part 25 and the extension holes 24 on the connecting plate 22 in sequence and fix the consumable mounting part 25.

[0051] Because the extension hole 24 is arranged along the height direction, when the distal end of the consumable mounting part 25 is pressed downward, the fastener can slide relative to it within the extension hole 24, thereby causing the upper mounting block 15 and the upper roller 13 to be lifted upward without interference from the connecting plate 22. The consumable mounting part 25 is used to mount a consumable box containing metal wire.

[0052] In use, place the consumable box on the consumable mounting part 25, and the operator manually pushes the push knob on the consumable box to push the metal wire out of the consumable box. The specific wire loading operation is as follows: press down on the far end of the consumable mounting part 25, the fastener moves upward along the extension hole 24, driving the upper mounting block 15 and the upper roller 13 to lift upward, so that the gap between the upper roller 13 and the lower roller 14 increases; then push the metal wire from the consumable box into the gap between the two rollers; finally release the consumable mounting part 25, the upper mounting block 15 and the upper roller 13 fall back, so that the upper roller 13 and the lower roller 14 press the metal wire again, completing the preparation work before wire feeding.

[0053] This solution allows for easy lifting of the upper roller 13 by pressing the far end of the consumable installation part 25 and utilizing the sliding engagement between the fastener and the extension hole 24, thereby increasing the roller gap and facilitating the insertion of the metal wire. After releasing, it automatically tightens due to gravity or the elastic reset component, requiring no additional tools and significantly reducing the difficulty and time of wire installation.

[0054] like Figure 5 As shown, in a specific embodiment, the abutment of the fixing part 17 of the upper mounting block 15 and the lower mounting block 16 is provided with a clearance part, the two clearance parts form a receiving groove, the receiving groove contains a fixing block 26, the fixing block 26 is fixed on the lower mounting block 16, and the thread outlet 27 is installed on the fixing block 26.

[0055] In this application, the fixing portions 17 of the upper mounting block 15 and the lower mounting block 16 are respectively provided with clearance portions at their mutual abutment positions, and the two clearance portions together form a groove. This groove is used to accommodate the fixing block 26, which is fixed to the lower mounting block 16 by fasteners. The thread outlet 27 is mounted on the fixing block 26.

[0056] The fixing block 26 in this design can further lock the relative position between the upper mounting block 15 and the lower mounting block 16, preventing misalignment during operation. Simultaneously, the groove serves to accommodate and position the fixing block 26, making the overall structure more compact and not affecting the arrangement of other components of the wire feeding mechanism 12. After the wire outlet nozzle 27 is installed on the fixing block 26, its inlet is aligned with the gap between the upper roller 13 and the lower roller 14, ensuring that the metal wire can smoothly enter the wire outlet nozzle 27 after being fed from the rollers and receive precise guidance, thereby improving the directional stability of wire feeding and the positioning accuracy of bending and shaping.

[0057] In one specific implementation, the shaping component 31 includes a pointer 32, a pointer mounting plate 33, and a sliding part; the sliding part includes a guide fixed to the support plate 28 and a slider that slides with the guide; the pointer mounting plate 33 is fixed to the slider; and the pointer 32 is mounted on the pointer mounting plate 33.

[0058] In this application, the shaping component 31 includes a pointer 32, a pointer mounting plate 33, and a sliding part. The sliding part consists of a guide member 36 fixed to a support plate 28 and a slider 37 that slides with the guide member. The pointer mounting plate 33 is fixedly mounted on the slider, and the pointer 32 is mounted on the pointer mounting plate 33.

[0059] With the above structure, the pointer 32 can move smoothly relative to the support plate 28 under the guidance of the sliding part, thereby approaching or moving away from the metal wire extending from the wire outlet 27, realizing the bending and shaping operation of the metal wire. The cooperation between the guide and the slider ensures the directionality and repeatability of the pointer 32's movement, which is beneficial to improving the shaping quality.

[0060] like Figure 2 As shown, in a specific embodiment, the pointer mounting plate 33 is a plate-shaped piece with a mounting groove 34 perpendicular to the plate surface along its edge; the support plate 28 is provided with a driving part 47, and the driving part 47 is disposed opposite to the pointer 32; the driving part 47 is connected to a connecting rod 48 through an eccentric shaft, and the other end of the connecting rod 48 is connected to the mounting groove 34 on the pointer mounting plate 33 to drive the pointer mounting plate 33 to move.

[0061] In this application, the pointer mounting plate 33 is a plate-shaped component with a mounting groove 34 perpendicular to the plate surface along its edge. A drive unit 47 is provided on the support plate 28, and the drive unit 47 is positioned opposite to the pointer 32. The drive unit 47 is connected to a connecting rod 48 via an eccentric shaft. The other end of the connecting rod 48 is connected to the mounting groove 34 on the pointer mounting plate 33 to drive the pointer mounting plate 33 to move. Specifically, when the drive unit 47 is working, the eccentric shaft rotates, causing the connecting rod 48 to swing. The connecting rod 48 pushes the pointer mounting plate 33 to reciprocate along a preset direction via the mounting groove 34, thereby causing the pointer 32 mounted on the pointer mounting plate 33 to move closer to or further away from the metal wire, achieving bending and shaping of the metal wire. This eccentric connecting rod drive method has a compact structure, can convert rotational motion into linear reciprocating motion, and has a controllable stroke, which is beneficial for precisely controlling the force applied to the pointer 32.

[0062] like Figure 2 As shown, in a specific embodiment, a limiting part 49 is provided protruding on the bearing plate 28; a limiting rod 50 is fixedly connected to the limiting part 49, and the other end of the limiting rod 50 passes through the moving block 35 below the pointer mounting plate 33. The moving block 35 has a through hole for the limiting rod 50 to pass through.

[0063] In this application, a limiting part 49 protrudes from the support plate 28, and a limiting rod 50 is fixedly connected to the limiting part 49. The other end of the limiting rod 50 passes through a movable block 35 below the pointer mounting plate 33. The movable block 35 has a through hole for the limiting rod 50 to pass through. The limiting part 49 acts as a fixed stop structure to limit the movement limit of the pointer mounting plate 33 towards the support plate 28, preventing the pointer mounting plate 33 from overtraveling and causing collisions or damage. The engagement between the limiting rod 50 and the through hole on the movable block 35 further guides the movement of the pointer mounting plate 33, preventing swaying or rotation.

[0064] like Figure 2 As shown, in a specific embodiment, the shaping component 31 further includes a photoelectric switch component 51; the photoelectric switch component 51 includes a detection unit 52 and a photoelectric switch control piece 53; the detection unit 52 is fixedly mounted on the carrier plate 28, and the photoelectric switch control piece 53 is disposed on the pointer mounting plate 33. The photoelectric switch control piece moves synchronously with the pointer mounting plate to trigger the detection unit 52 to generate a detection signal.

[0065] In this application, the shaping assembly 31 further includes a photoelectric switch assembly 51, which includes a detection unit 52 and a photoelectric switch control piece 53. The detection unit 52 is fixedly mounted on the support plate 28 and has a detection groove thereon. The photoelectric switch control piece 53 is located on the side of the pointer mounting plate 33 away from the shaping pointer 32. The photoelectric switch control piece 53 moves synchronously with the pointer mounting plate 33 and can enter or exit the detection groove of the detection unit 52. When the photoelectric switch control piece 53 enters the detection groove, the photoelectric switch assembly 51 is triggered, generating a position signal, thereby determining whether the pointer mounting plate 33 has moved into place.
