Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically to a stamping bearing mechanism and a stamping device. Background Technology

[0002] During surgery, the placement of a vascular stent is crucial. Even with angiography, doctors cannot always determine if the stent has accurately reached the lesion site after insertion. They must rely on the imaging points on the stent to make a determination. Therefore, it is essential to quickly, accurately, and reliably imprint imaging points onto the stent.

[0003] Currently, when stamping and assembling contrast points on vascular stents, a support rod is often used to coaxially fit the vascular stent onto the support rod to support the vascular stent and its contrast holes. When the stamping mechanism directly applies stamping pressure to the contrast ring of the stent to press and assemble the contrast points into the contrast holes, it not only puts a large stamping pressure on the vascular stent, but also subjects the support rod as a whole to stamping pressure. This may cause deformation and damage to the vascular stent and the support rod. Moreover, due to the lack of a structure to position the contrast ring, there is a possibility of the contrast ring shifting, which may lead to poor assembly of the contrast points. Utility Model Content

[0004] In view of this, this application provides a stamping bearing mechanism and a stamping device, which solves the problems of deformation and damage to vascular stents caused by excessive stamping by the stamping working mechanism, and poor assembly caused by the movement of the imaging ring.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A stamping support mechanism for supporting a vascular stent and cooperating with a stamping working mechanism to stamp and assemble a contrast agent into the contrast ring of the vascular stent, comprising:

[0007] The stent platform has a placement slot for placing the vascular stent to be stamped.

[0008] A developing ring stamping station is located at one end of the support platform. The developing ring stamping station has a stamping groove for accommodating the stamping head of the stamping working mechanism. The stamping groove has a bottom surface, and a positioning groove is formed on the bottom surface of the stamping groove for accommodating the developing ring. The developing ring stamping station is used to limit the stroke of the stamping head from not exceeding the stamping groove and / or the positioning groove.

[0009] Optionally, the positioning groove can engage the developing ring; or,

[0010] The bottom surface of the positioning groove is provided with a limiting protrusion, the thickness of which is less than the thickness of the developing ring, allowing the developing ring to be fitted onto the limiting protrusion; or...

[0011] The bottom surface of the positioning groove is provided with a stamping groove, and the bottom of the stamped developing piece can extend into the stamping groove.

[0012] Optionally, the stamping groove and the positioning groove have a first notch and a second notch respectively on the side near the support platform, and the cross-sectional area of ​​the stamping groove is larger than the cross-sectional area of ​​the positioning groove.

[0013] Optionally, the developing ring stamping table includes a support base and a positioning base, the support base is disposed on the positioning base, and the stamping groove is formed in the support base and the positioning groove is formed in the positioning base.

[0014] Optionally, the end face of the positioning seat near the support platform is provided with a plurality of clearance grooves;

[0015] The vascular stent has a plurality of imaging rings along its circumference at one end. When the vascular stent is stamped, at least a portion of the imaging rings can be accommodated in the clearance groove.

[0016] Optionally, it also includes a displacement adjustment mechanism, which carries the stent stage and can drive the stent stage to move so that the contrast ring of the vascular stent to be punched is positioned in the positioning groove;

[0017] The displacement adjustment mechanism includes:

[0018] The first receiving platform supports the support frame.

[0019] The transmission component supports the first receiving platform and is capable of telescopic movement;

[0020] A locking knob is rotatable to lock or unlock the telescopic movement of the transmission assembly.

[0021] The adjustment knob can be rotated to adjust the telescopic displacement of the transmission assembly.

[0022] This application also provides a stamping apparatus, including a stamping working mechanism and a stamping bearing mechanism as described above, the stamping working mechanism including a workpiece configured to apply pressure toward the positioning groove of the stamping bearing mechanism, the workpiece including a stamping head opposite to the positioning groove.

[0023] Optionally, the stamping mechanism includes a stand, which is disposed on the developing ring stamping table, and the stand has a mounting hole; the workpiece is movably inserted into the mounting hole;

[0024] The stamping mechanism includes a reset component, which drives the workpiece to reset when no external force is applied to the workpiece.

[0025] Optionally, a power mechanism is included, which is capable of pressing or releasing the workpiece to provide or cancel the power to press the workpiece onto the stamping bearing mechanism.

[0026] Optionally, the stamping device includes a base assembly to support the stamping working mechanism, the displacement adjustment mechanism, and the power mechanism;

[0027] And / or,

[0033] The stamping support mechanism and stamping device provided in this application include a stent stage and a contrast ring stamping stage, which provide zoned support for the vascular stent body and the contrast ring of the vascular stent, enabling targeted stamping of the contrast ring. Furthermore, the contrast ring stamping stage has stamping grooves and positioning grooves, allowing the contrast ring of the vascular stent to be positioned within the positioning grooves while limiting the stroke of the stamping head. As such, the stent stage no longer serves as the force-bearing area supporting the contrast element during stamping; instead, the force-bearing area for supporting the contrast element is transferred to the stamping support stage. Clearly, this significantly improves the stamping efficiency. The pressing mechanism no longer applies pressure to the stent stage, preventing deformation and damage. Furthermore, due to the presence of the pressing groove and positioning groove, the pressing head can enter the positioning groove from the pressing groove to contact the imaging element during the pressing operation. The pressing head is limited by the imaging ring pressing table to prevent excessive pressing, thus avoiding deformation and damage to the vascular stent. Moreover, the positioning groove can accurately position the imaging ring, preventing displacement of the imaging ring during the pressing assembly process. This makes it easier to align and assemble the imaging element into the imaging ring, improving the pressing assembly yield of the imaging element. Attached Figure Description

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] like Figure 1-5 As shown, this application provides a stamping support mechanism 100 and a stamping device with the support mechanism. The stamping support mechanism 100 is used to support the vascular stent 7 and can cooperate with the stamping working mechanism 200 to stamp and assemble the radiopaque element 10 into the radiopaque ring 71 of the vascular stent 7.

[0052] The stamping support mechanism 100 includes a stent stage 1 and a contrast ring stamping platform 2. The stent stage 1 has a placement groove 11 for placing the vascular stent 7 to be stamped. The contrast ring stamping platform 2 is located at one end of the stent stage 1. The contrast ring stamping platform 2 has a stamping groove 211 for accommodating the stamping head 41 of the stamping working mechanism 200. The stamping head 41 can be relatively close to or away from the contrast ring stamping platform 2. The stamping groove 211 has a bottom surface. A positioning groove 221 is provided on the bottom surface of the stamping groove 211 for accommodating the contrast ring 71. The contrast ring stamping platform 2 is used to limit the stroke of the stamping head 41 from not exceeding the stamping groove 211 and / or the positioning groove 221.

[0053] The stent 7 and the contrast ring 71 on the stent 7 are placed in sections by the stent stage 1 and the contrast ring stamping stage 2, which avoids damage to the stent stage 1 that supports the stent 7. Moreover, the contrast ring stamping stage 2 has a stamping groove 211 and a positioning groove 221. The positioning groove 221 achieves precise positioning of the contrast ring 71, and the contrast ring 71 no longer moves out of place. This makes it easier for the contrasting component 10 to be aligned and assembled into the contrast ring 71, improving the stamping assembly yield of the contrasting component 10. In addition, the contrast stamping stage can limit the stamping head 41 from excessively pressing and squeezing the contrast ring 71. Only a part of the bottom end of the stamping head 41 can extend into the stamping groove 211, while the other part is blocked by the contrast ring stamping stage 2 structure around the stamping groove 211, avoiding deformation and damage to the contrast ring 71 caused by excessive stroke of the stamping head 41.

[0054] It should be noted that the vascular stent 7 includes, but is not limited to, arteriovenous stents or transcatheter aortic valves, etc., and the aforementioned devices usually have imaging points at their ends for imaging. Along the axial direction of the vascular stent 7, the vascular stent 7 has two open ends; typically, both open ends of the vascular stent 7 form imaging rings 71; and along the axial direction of the vascular stent 7, the imaging rings 71 protrude relative to other areas, so that the imaging rings 71 of the vascular stent 7 supported on the stent stage 1 extend to the positioning groove 221. Along the circumferential direction of the vascular stent 7, the number of imaging rings 71 at each open end is one or more; each imaging ring 71 is provided with an imaging element 10; the material of the imaging element 10 is usually a precious metal such as gold, platinum, platinum-iridium alloy, tantalum, etc.; the shape of the imaging element 10 before stamping assembly is spherical, disc-shaped, wire-shaped, etc. Preferably, the imaging element 10 is spherical and has a certain degree of ductility.

[0055] It should be further explained that the developing ring stamping table 2 includes a support base 21 and a positioning base 22, and the support base 21 can be a liner structure. Furthermore, the support base 21 is fixed on the positioning base 22.

[0056] Please see the appendix Figure 1 Furthermore, the stent stage 1 has an extension length, and the direction of the extension length is parallel to the length direction of the vascular stent 7; a placement groove 11 is formed on the surface of the stent stage 1 to hold the stent in place. Further still, the cross-sectional shape of the placement groove 11 is V-shaped, arc-shaped, etc.; preferably, the cross-sectional shape of the placement groove 11 is V-shaped.

[0057] Along the extension length of the stent stage 1, the imaging ring stamping station 2 is located on one side of the stent stage 1, and the side of the positioning groove 221 near the stent stage 1 is a material gap, so that the imaging ring 71 located at the opening end of the vascular stent 7 can extend into the positioning groove 221 without obstruction.

[0058] It should be further explained that the step of stamping and assembling the developing element 10 into the developing ring 71 includes:

[0059] Place the vascular stent 7 in the placement slot 11 of the stent stage 1, and extend and position the contrast ring 71 located at the open end of the vascular stent 7 into the positioning slot 221 of the positioning seat 22.

[0060] Place the developing piece 10 at the developing ring 71;

[0061] Sufficient load-bearing force is provided to the working piece 4 so that the working piece 4 punches the developing piece 10, thereby punching and assembling the developing piece 10 into the developing ring 71.

[0062] In the above steps, the support stage 1 no longer serves as the force-bearing area supporting the developing part 10 during stamping. Instead, the force-bearing area is transferred to the bearing seat 21 of the stamping working mechanism 200. Obviously, the working part 4 will not cause stamping on the support stage 1, thus avoiding deformation and damage to the support stage 1. Furthermore, due to the presence of the positioning groove 221, the developing ring 71 can be accurately positioned. During the stamping assembly process, the developing ring 71 will no longer shift, making it easier for the developing part 10 to be aligned and assembled into the developing ring 71, thereby improving the stamping assembly yield of the developing part 10.

[0063] In some embodiments, the stamping area of ​​the stamping mechanism 200 is larger than the cross-sectional area of ​​the positioning groove 221 along the stamping direction. The stamping direction is parallel to the direction from the workpiece 4 to the bearing seat 21, i.e., attached... Figure 1 The direction indicated by the middle arrow.

[0064] As described above, the working piece 4 punches the developing piece 10. Due to the presence of the positioning groove 221 and the fact that the punching area of ​​the working piece 4 is larger than the cross-sectional area of ​​the positioning groove 221 along the punching direction, during the punching process of the working piece 4, the working piece 4 will only punch the area of ​​the bearing seat 21 other than the positioning groove 221, and will not punch the inside of the positioning groove 221. Therefore, the working piece 4 will not punch the developing ring 71 located in the positioning groove 221, thus avoiding deformation and damage to the bracket.

[0065] Please see the appendix Figure 2-3 In some embodiments of this application, the working piece 4 includes a stamping head 41 located near the support 21. The support 21 has a stamping groove 211 opposite to the position of the stamping head 41. A positioning groove 221 is formed on the bottom surface of the stamping groove 211.

[0066] It should be noted that, on the side near the support platform 1, the stamping groove 211 has a first notch, and the positioning groove 221 has a second notch. The stamping area of ​​the workpiece 4 is the cross-sectional area of ​​the stamping head 41.

[0067] On the side near the support stage 1, the stamping groove 211 has a first notch and the positioning groove 221 has a second notch; as above, it can ensure that the developing ring 71 of the support can extend and be positioned in the positioning groove 221 without obstruction; and when the developing element 10 fails to be successfully stamped and assembled into the developing ring 71, the presence of the first notch facilitates the recycling of the waste developing element 10.

[0068] It should be further noted that the cross-sectional area of ​​the stamping head 41 is smaller than the cross-sectional area of ​​the stamping groove 211 along the stamping direction, and the cross-sectional area of ​​the stamping head 41 is larger than the cross-sectional area of ​​the positioning groove 221 along the stamping direction.

[0069] As shown above, the stamping area of ​​the stamping head 41 can be precisely limited, and the stamping head 41 only stamps the bottom surface of the stamping groove 211; when the stamping head 41 stamps the developing element 10, it can not only ensure the stamping area of ​​the stamping head 41 in contact with the developing element 10, but also avoid stamping damage to the developing ring 71 in the positioning groove 221.

[0070] In order to make the positioning groove 221 more accurately hold the developing ring 71, the width of the positioning groove 221 can be designed to be the same as the width of the developing ring 71, and the top surface of the positioning seat 22 can be used as the plane to receive the developing element 10.

[0071] Please see the appendix Figure 3 In some embodiments of this application, a receiving groove 222 is provided on the bottom surface of the positioning groove 221. The bottom of the stamped developing piece 10 is located in the receiving groove 222.

[0072] It should be noted that the receiving groove 222 is a groove structure adapted to the shape of the developing element 10; when the developing element 10 is a developing ball, the receiving groove 222 is a cylindrical groove.

[0073] When the working part 4 presses the developing part 10 and assembles the developing part 10 into the developing ring 71, the receiving groove 222 provides a receiving space for the area of ​​the developing part 10 away from the working part 4. As described above, the deformation of the developing part 10 is not limited to the space enclosed by the developing ring 71. The developing part 10 can protrude from the developing ring 71 in a direction away from the working part 4, thereby avoiding excessive compression deformation of the surrounding wall of the developing ring 71 and ensuring a reliable and stable assembly of the developing part 10 in the developing ring 71.

[0074] In other embodiments of this application, a limiting protrusion may be provided on the bottom surface of the positioning groove 221, and the developing ring 71 may be sleeved and fixed to the limiting protrusion. The thickness of the limiting protrusion is less than the thickness of the developing ring 71, so that there is enough space inside the developing ring 71 to install the developing element 10.

[0075] Please see the appendix Figure 1 In some embodiments of this application, the stamping working mechanism 200 includes a positioning seat 22. A positioning area is formed on the end face of the positioning seat 22 near the stent stage 1, and the positioning area has a plurality of clearance grooves 223. The vascular stent 7 includes a first open end near the positioning area, and has a plurality of radiopaque rings 71 along the circumference of the first open end. Several local areas of the first open end are respectively positioned within the plurality of clearance grooves 223.

[0076] It should be noted that the clearance groove 223 is a racetrack-shaped groove. More preferably, there are three clearance grooves 223, one of which is vertically arranged, and the other two clearance grooves 223 are symmetrically arranged about the vertical clearance groove 223, and the two symmetrical clearance grooves 223 are inclined from top to bottom in a direction away from each other.

[0077] As described above, this achieves avoidance of other non-punching imaging rings 71, enables the cooperation between the end of the vascular stent 7 and the positioning seat 22, and also achieves three-point snap-fit ​​positioning of the vascular stent 7, ensuring reliable fixation of the vascular stent 7, avoiding misalignment of the vascular stent 7, and achieving precise punching of the imaging element 10.

[0078] The shape and arrangement of the clearance grooves 223 ensure that vascular stents 7 of different sizes can extend into the three clearance grooves 223 in a localized area, making them highly flexible and adaptable.

[0079] Please see the appendix Figure 1 , 4 In some embodiments of this application, the stamping device includes a displacement adjustment mechanism 3. The displacement adjustment mechanism 3 supports the support stage 1 and can drive the support stage 1 to move along the stamping direction so that the developing ring 71 of the support is positioned in the positioning groove 221.

[0080] It should be noted that the displacement adjustment mechanism 3 drives the support platform 1 to move at the micrometer level.

[0081] By setting the displacement adjustment mechanism 3, it can be ensured that the imaging ring 71 of vascular stents 7 of different specifications and sizes can be adjusted to be precisely positioned in the positioning groove 221, and the imaging ring 71 will not protrude out of the positioning groove 221, thus avoiding the punching head 41 from causing punching damage to the imaging ring 71.

[0082] See attached document for details Figure 4 In some embodiments of this application, the displacement adjustment mechanism 3 includes: a first receiving platform 31, a transmission assembly, a locking knob 32, and an adjusting knob 33. The first receiving platform 31 receives the support platform 1. The transmission assembly supports the first receiving platform 31 and is capable of telescopic movement. The locking knob 32 is rotatable to lock or unlock the telescopic movement of the transmission assembly. The adjusting knob 33 is rotatable to adjust the telescopic displacement of the transmission assembly.

[0083] The adjustment knob 33 allows for locking or unlocking of the telescopic movement of the transmission component, avoiding the risk of functional failure caused by accidental triggering of the adjustment knob 33. Rotating the adjustment knob 33 enables the telescopic movement of the transmission component. For example, when the adjustment knob 33 is rotated clockwise, the transmission component extends, thereby causing the first receiving platform 31 and the support platform 1 to move upwards; when the adjustment knob 33 is rotated counterclockwise, the transmission component shortens, thereby causing the first receiving platform 31 and the support platform 1 to move downwards.

[0084] Furthermore, the displacement adjustment mechanism 3 also includes a second receiving platform 34; the second receiving platform 34 receives the transmission component; and further still, the outer periphery of the transmission component can be covered with a protective shell.

[0085] In some embodiments, the transmission assembly includes a first gear, a first rack, and a telescopic support rod; the first rack includes a first side and a second side, both sides being provided with meshing teeth; one end of the first rack is fixedly connected to the first receiving platform 31, and the first side of the other end meshes with the first gear, and has space to move downwards; the telescopic support rod is supported between the first receiving platform 31 and the second receiving platform 34, and is capable of telescopic deformation; the adjusting knob 33 is coaxially connected to the first gear. The transmission assembly also includes a second gear, a second rack, and a locking chuck; the second rack is perpendicular to the first rack, and a locking chuck is fixedly connected to the end of the second rack near the first rack, the locking chuck being able to engage with the meshing teeth on the second side of the first rack; the end of the second rack away from the first rack meshes with the second gear; the locking knob 32 is coaxially connected to the second gear.

[0086] During operation, rotating the adjustment knob 33 in the forward direction causes the first gear to rotate, which in turn moves the first rack closer to the first receiving platform 31. Simultaneously, the telescopic support rod extends, thus elongating the transmission assembly. Rotating the adjustment knob 33 in the reverse direction causes the first gear to rotate, which in turn moves the first rack away from the first receiving platform 31. Simultaneously, the telescopic support rod shortens, thus shortening the transmission assembly.

[0087] Rotating the locking knob 32 in the forward direction causes the second gear to rotate, which in turn drives the second rack to move closer to the first rack until the locking chuck engages with the meshing teeth on the second side of the first rack. At this point, the first rack is locked, and the adjusting knob 33 cannot rotate, thus locking the telescopic movement of the transmission component. Rotating the locking knob 32 in the reverse direction causes the second gear to rotate, which in turn drives the second rack to move away from the first rack until the locking chuck disengages from the meshing teeth on the second side of the first rack. At this point, the first rack is released from locking and can move with the rotation of the adjusting knob 33, thus releasing the telescopic movement of the transmission component.

[0088] Please see the appendix Figure 1 , 5 In some embodiments of this application, the stamping device includes a power mechanism 5, which is separately configured from the stamping working mechanism 200, and provides power to the workpiece 4 through the power mechanism 5.

[0089] It should be noted that the power mechanism 5 includes a power telescopic component 52. The power telescopic component 52 is separate from the working component 4, and the power telescopic component 52 can extend and retract to press against or release the pressure on the working component 4.

[0090] When the power telescopic member 52 extends towards the working part 4, it presses against the working part 4, providing the working part 4 with the pressure to press against the developing element 10; when the power telescopic member 52 retracts away from the working part 4, it no longer presses against the working part 4, and the working part 4 no longer has the pressure to press against the developing element 10.

[0091] The stamping working mechanism 200 is set independently of the power mechanism 5. Only the working part 4 of the stamping working mechanism 200 can be precisely set to adapt it to the imaging ring 71 of the vascular stent 7. The power mechanism 5 can be a structural component that can provide sufficient stamping force, so that it can act on or release the working part 4. There is no need to make major improvements to the power mechanism 5, thus saving the research and development and manufacturing costs of the stamping device.

[0092] It should be noted that the working part 4 includes a pressing surface 411 away from the stamping head 41; the power mechanism 5 can press against the pressing surface 411 and has a sufficient pressing contact area with the pressing surface 411; the area of ​​the pressing surface 411 is larger than the cross-sectional area of ​​the stamping head 41.

[0093] Please see the appendix Figure 1Furthermore, the power mechanism 5 includes a support portion 51, a power telescopic member 52, and a controller 53; the power telescopic member 52 and the controller 53 are fixedly mounted on the support portion 51; the controller 53 controls the movement of the telescopic rod 522 of the power telescopic member 52, so as to drive the action of the pressure surface 411 through the telescopic rod 522. Please refer to the appendix. Figure 5 The power telescopic component 52 is any one of the telescopic cylinder 521, telescopic hydraulic cylinder, and telescopic electric cylinder; preferably, the power telescopic component 52 is a telescopic cylinder 521, and the power telescopic component 52 includes a cylinder 521 and a telescopic rod 522.

[0094] Please see the appendix Figure 2 In some embodiments of this application, the stamping mechanism 200 includes a support frame 42. The support frame 42 has a mounting hole; the workpiece 4 is movably inserted into the mounting hole. The stamping mechanism 200 includes a reset member 43, which, when the power mechanism 5 stops providing power to the workpiece 4, drives the workpiece 4 to reset.

[0095] It should be noted that the upright frame 42 is an inverted L-shaped upright frame 42, which includes a vertical part and a horizontal part. The vertical part is fixed to the positioning seat 22, and the horizontal part is parallel to the positioning seat 22. The upright frame 42 and the positioning seat 22 form a U-shaped structure; the mounting hole is opened in the horizontal part of the upright frame 42.

[0096] The automatic reset of the working part 4 is achieved by setting the reset component 43, which eliminates the need for manual operation, saves labor costs, and saves time and effort.

[0097] Furthermore, the reset member 43 can be a spring, which is sleeved on the outside of the working member 4. One end of the spring is fixed to the pressing plane 411, and the other end is fixed to the horizontal part of the upright 42.

[0098] When the power mechanism 5 presses against the pressing surface 411, the working part 4 moves downward as a whole, and the spring is compressed. When the power mechanism 5 releases from pressing against the pressing surface 411, the power mechanism 5 disengages from the pressing surface 411; at this time, the pressure that caused the spring to compress and deform disappears, the spring returns to its initial state, and then drives the working part 4 to return to its initial position.

[0099] In some embodiments of this application, the stamping working mechanism 200 includes a bushing 44, which is fixedly connected to the stand 42, and the bushing 44 extends at least partially into the mounting hole; the working piece 4 is movably inserted into the bushing 44.

[0100] It should be noted that bushing 44 can be replaced according to its own wear condition.

[0101] By setting bushing 44, wear caused by the telescopic movement of working part 4 to the mounting hole can be avoided, thereby ensuring the structural stability of the upright 42 and extending the service life of the device.

[0102] Please see the appendix Figure 1 In some embodiments of this application, the stamping device includes a base assembly 6, which supports the stamping working mechanism 200, the displacement adjustment mechanism 3, and the power mechanism 5.

[0103] It should be noted that the base assembly 6 includes a first base 61, to which the second receiving platform 34 of the displacement adjustment mechanism 3 is fixed. The base assembly 6 also includes a second base 62, which has a supporting height and is fixed to the first base 61; the supporting part 51 of the power mechanism 5 is fixed to the second base 62.
