[0040] Please refer to Figures 1 to 4 , an electrode shaping device 100 is provided in an embodiment of this application, which includes a support assembly 10, an upper die assembly 20, and a lower die assembly 30. The upper die assembly 20 is installed on the support assembly 10 and can move relative to the lower die assembly 30 in the vertical direction. The lower die assembly 30 is located below the upper die assembly 20. A catheter positioning groove 321 for accommodating a catheter 200 is provided at the top of the lower die assembly 30. An electrode positioning boss 322 for placing an electrode 300 is arranged at a position corresponding to the upper die assembly 20 in the catheter positioning groove 321. The electrode positioning boss 322 is used to cooperate with the upper die assembly 20 to form a cavity 40 that defines the shape and size of the electrode 300.
[0041] During operation, the electrode 300 is sleeved on the catheter 200, and then the catheter 200 is placed in the catheter positioning groove 321 of the lower die assembly 30, and the electrode 300 on the catheter 200 is placed on the electrode positioning boss 322 in the catheter positioning groove 321. Then, the upper die assembly 20 is moved downward to flatten the electrode 300. The cavity 40 formed by the cooperation of the electrode positioning boss 322 and the upper die assembly 20 defines the shape and size of the electrode 300. By providing the catheter positioning groove 321 in the lower die assembly 30 and placing the catheter 200 in the catheter positioning groove 321, the positioning of the catheter 200 can be achieved, effectively avoiding the shaking and skew of the catheter 200, thereby facilitating the shaping of the electrode 300 and improving work efficiency; by providing the electrode positioning boss 322 corresponding to the upper die assembly 20 in the catheter positioning groove 321 and placing the electrode 300 on the electrode positioning boss 322, the positioning of the electrode 300 can be achieved, ensuring that the upper die assembly 20 can accurately press on the electrode 300 and improving work reliability; by forming the cavity 40 through the cooperation of the electrode positioning boss 322 and the upper die assembly 20 to define the shape and size of the electrode 300, the shape and size of the electrode 300 can be accurately controlled, ensuring that the catheter 200 equipped with the electrode 300 can smoothly pass through the sheath during pulsed electric field ablation.
[0042] Specifically, in combination with Figure 3 、 Figure 4 and 6As shown, a "m"-shaped upper shaping groove 211 is provided at the bottom of the upper die assembly 20, and a lower shaping groove 3221 with an arc surface is provided at the top of the electrode positioning boss 322. When the upper die assembly 20 is docked with the electrode positioning boss 322, the upper shaping groove 211 and the lower shaping groove 3221 cooperate to form a cavity 40. The shape of the shaped electrode 300 is as Figure 9 shown.
[0043] Specifically, the electrode positioning boss 322 can accommodate two electrodes 300 simultaneously. When placing the two electrodes 300 on the electrode positioning boss 322, the ends of the two electrodes 300 away from each other are aligned with the opposite ends of the electrode positioning boss 322 respectively, so as to control the distance between the two electrodes 300 and ensure that the distance between the two electrodes 300 is consistent each time they are installed.
[0044] In one embodiment, in combination with Figure 1 and Figure 5 shown, the support assembly 10 includes a linear guide rail 11 and a slider 12. The linear guide rail 11 extends in the vertical direction, and the slider 12 is slidably engaged with the linear guide rail 11. The upper die assembly 20 is fixedly connected to the slider 12. Through the cooperation of the linear guide rail 11 and the slider 12, it can ensure that the upper die assembly 20 moves stably in the vertical direction, so as to ensure the precise docking of the upper die assembly 20 with the electrode positioning boss 322, and further precisely control the shape and size of the electrode 300.
[0045] In one embodiment, in combination with Figure 1 and Figure 5 shown, the support assembly 10 further includes a base 13 and a fixing frame 14. The lower die assembly 30 and the fixing frame 14 are both arranged on the base 13, and the linear guide rail 11 is installed on the side of the fixing frame 14 facing the lower die assembly 30. The base 13 can support the fixing frame 14 and the lower die assembly 30. By arranging the fixing frame 14 and the lower die assembly 30 together on the base 13, on the one hand, it is convenient for handling, and on the other hand, it can simplify the structure and make the overall structure more compact; the fixing frame 14 supports the linear guide rail 11. By installing the linear guide rail 11 on the side of the fixing frame 14 facing the lower die assembly 30, it is convenient to arrange the upper die assembly 20 directly above the lower die assembly 30. Specifically, the fixing frame 14 is a plate-like structure, perpendicular to the base 13, with a simple structure, low manufacturing cost, and convenient for installing the linear guide rail 11. The linear guide rail 11 can be fixed to the fixing frame 14 by screws, and the fixing frame 14 and the lower die assembly 30 can also be fixed to the base 13 by screws.
[0046] In one embodiment, in combination with Figure 1 , Figure 5 and Figure 7As shown, the fixing bracket 14 is attached to the peripheral side of the lower die assembly 30. A second installation groove 311 is provided on the side of the lower die assembly 30 facing the fixing bracket 14. The second installation groove 311 penetrates upward through the top of the lower die assembly 30. The bottom end of the linear guide rail 11 is embedded in the second installation groove 311, and the top end of the linear guide rail 11 extends out of the second installation groove 311 to cooperate with the slider 12. By providing the second installation groove 311 on the side of the lower die assembly 30 facing the fixing bracket 14, the bottom end of the linear guide rail 11 is embedded in the second installation groove 311 without protruding from the surface of the peripheral side of the lower die assembly 30, so as to satisfy the attachment of the fixing bracket 14 to the peripheral side of the lower die assembly 30, making the overall structure more compact. And the second installation groove 311 penetrates upward through the top of the lower die assembly 30, so as to satisfy the extension of the top end of the linear guide rail 11 out of the second installation groove 311 to cooperate with the slider 12. In addition, the bottom end of the linear guide rail 11 extends downward into the second installation groove 311, that is, below the top surface of the lower die assembly 30. Thus, during the process of the upper die assembly 20 moving downward to dock with the electrode positioning boss 322, the linear guide rail 11 can continuously provide a guiding function for the upper die assembly 20. Specifically, the fixing bracket 14 and the lower die assembly 30 can be fixedly connected by screws.
[0047] In one embodiment, as Figure 5 shown, the support assembly 10 further includes a plurality of rubber feet 15, and the plurality of rubber feet 15 are all arranged at the bottom of the base 13, playing roles such as anti-slip and heightening.
[0048] In one embodiment, in combination with Figure 1 and Figure 6As shown, the upper mold assembly 20 includes an upper mold body 21 and an upper mold mounting table 22. The upper mold body 21 is used to cooperate with the electrode positioning boss 322. The upper mold body 21 is detachably mounted on the bottom of the upper mold mounting table 22, and the upper mold mounting table 22 is mounted on the support assembly 10. The function of the upper mold body 21 is to cooperate with the electrode positioning boss 322 to form a cavity 40. The upper mold mounting table 22 is connected between the upper mold body 21 and the support assembly 10, playing a supporting role for the upper mold body 21 and being used to drive the upper mold body 21 to move in the vertical direction, so as to realize the docking and separation of the upper mold body 21 and the electrode positioning boss 322. The upper mold body 21 is detachably mounted on the bottom of the upper mold mounting table 22. On the one hand, it is convenient to finely adjust the position of the upper mold body 21 to improve the accuracy of flattening the electrode 300. On the other hand, different upper mold bodies 21 can be replaced to meet the shaping of electrodes 300 of different sizes and shapes. Specifically, the upper mold mounting table 22 is fixedly connected to the slider 12 in the support assembly 10. The slider 12 cooperates with the linear guide rail 11 to make the upper mold mounting table 22 move in the vertical direction, and the upper mold mounting table 22 then drives the upper mold body 21 to move in the vertical direction. Specifically, the upper mold mounting table 22 includes a vertical mounting plate 221 and a positioning block 222. One side of the vertical mounting plate 221 is fixedly connected to the slider 12. The positioning block 222 is fixedly arranged on the side of the vertical mounting plate 221 facing away from the slider 12. The upper mold body 21 is arranged at the bottom of the positioning block 222. The vertical mounting plate 221 and the slider 12 can be fixedly connected by screws. The positioning block 222 and the vertical mounting plate 221 can be an integral structure, and the upper mold body 21 can be installed on the positioning block 222 by screws.
[0049] In one embodiment, as Figure 7As shown, the lower die assembly 30 includes a lower die mounting table 31 and a lower die body 32. A receiving groove 312 is provided at the top of the lower die mounting table 31. The lower die body 32 is detachably disposed in the receiving groove 312. A conduit positioning groove 321 is provided at the top of the lower die body 32. The lower die body 32 is detachably connected to the lower die mounting table 31. On the one hand, it is convenient to finely adjust the position of the lower die body 32 to improve the accuracy of flattening the electrode 300. On the other hand, different lower die bodies 32 can be replaced to install conduits 200 and electrodes 300 of different sizes and dimensions for positioning. By providing the receiving groove 312 at the top of the lower die mounting table 31 and disposing the lower die body 32 in the receiving groove 312, not only can the lower die body 32 be positioned for easy installation, but also the lower die body 32 can be protected. In addition, the height of the lower die body 32 can be reduced, thereby correspondingly reducing the height of the upper die assembly 20 and making the overall structure center of gravity more stable. Specifically, a second mounting groove 311 is provided on the peripheral side of the lower die mounting table 31. The second mounting groove 311 penetrates upward through the top of the lower die mounting table 31. The lower die mounting table 31 is disposed on the base 13 of the support assembly 10. The lower die mounting table 31 can be fixed to the base 13 by screws, and the lower die body 32 can be fixed in the receiving groove 312 by screws.
[0050] In one embodiment, in combination with Figure 3 and Figure 6 As shown, the upper die body 21 is provided with a positioning hole 212, and a positioning post 323 is provided on the lower die body 32. The positioning post 323 is in plug-in fit with the positioning hole 212. Through the cooperation of the positioning post 323 and the positioning hole 212, the positioning between the upper die body 21 and the lower die body 32 can be achieved, ensuring the precise docking of the upper die body 21 and the electrode positioning boss 322, thereby precisely controlling the shape and size of the electrode 300.
[0051] In one embodiment, as shown in Figure 1As shown, the electrode shaping device 100 further includes a mold closing gap adjustment mechanism 50. The mold closing gap adjustment mechanism 50 is used to adjust the gap between the upper mold assembly 20 and the lower mold assembly 30 when the upper mold assembly 20 moves downward to the end, so as to adjust the size of the cavity 40. It should be noted that the upper mold assembly 20 moving downward to the end means that the upper mold assembly 20 moves downward to the limit and cannot move further downward. It can be understood that the larger the gap between the upper mold assembly 20 and the lower mold assembly 30 when the upper mold assembly 20 moves downward to the end, the larger the space of the cavity 40, and the larger and closer to a circular ring the outer shape of the shaped electrode 300 is. On the contrary, the smaller the gap between the upper mold assembly 20 and the lower mold assembly 30 when the upper mold assembly 20 moves downward to the end, the smaller the space of the cavity 40, and the smaller and flatter the outer shape of the shaped electrode 300 is. By adjusting the size of the cavity 40 through the mold closing gap adjustment mechanism 50, the size and shape of the shaped electrode 300 can be adjusted, and there is no need to design multiple molds according to the different sizes and shapes of the electrode 300, thus reducing the production cost. In addition, the catheter 200 is generally made of an elastic plastic material, such as Pebax, PA, TPU, etc., and the electrode 300 is generally made of platinum-iridium metal. If when the upper mold assembly 20 moves downward to the end, the electrode 300 causes the catheter 200 to be compressed and generate excessive deformation, then when the upper mold assembly 20 is removed, the catheter 200 will recover and may expand the electrode 300, which will cause the shape and size of the electrode 300 to be uncontrollable and it is difficult to ensure that the shape and size of the electrode 300 match the cavity 40. However, in this embodiment, the size of the cavity 40 can be adjusted according to the size of the catheter 200, avoiding excessive deformation of the catheter 200, so that the shape and size of the electrode 300 are controllable and the shape and size of the electrode 300 are ensured to match the cavity 40.
[0052] In one embodiment, in combination with Figure 4 、 Figure 7 and Figure 8As shown, the mold clamping gap adjusting mechanism 50 includes an installation component 51 and a threaded adjusting member 52. The installation component 51 is provided with a threaded hole 5141, and the threaded adjusting member 52 is threadedly connected to the threaded hole 5141. When the threaded adjusting member 52 rotates, it can move in the vertical direction. The top end of the threaded adjusting member 52 extends out of the threaded hole 5141 and is used to abut against the bottom of the upper mold assembly 20. When the upper mold assembly 20 moves downward to abut against the top end of the threaded adjusting member 52, the upper mold assembly 20 reaches the end. It can be understood that the higher the height of the top end of the threaded adjusting member 52, the larger the gap between the upper mold assembly 20 and the lower mold assembly 30 when the upper mold assembly 20 moves downward to the end. On the contrary, the lower the height of the top end of the threaded adjusting member 52, the smaller the gap between the upper mold assembly 20 and the lower mold assembly 30 when the upper mold assembly 20 moves downward to the end. When the threaded adjusting member 52 is rotated, through the threaded cooperation between the threaded adjusting member 52 and the threaded hole 5141, the threaded adjusting member 52 can be driven to move in the vertical direction, so as to adjust the height of the top end of the threaded adjusting member 52, and further adjust the gap between the upper mold assembly 20 and the lower mold assembly 30.
[0053] In one embodiment, in combination with Figure 4 and Figure 6 As shown, the top end of the threaded adjusting member 52 is used to abut against the bottom of the upper mold mounting table 22 in the upper mold assembly 20. By controlling the height of the upper mold mounting table 22, the height of the upper mold body 21 can be controlled, so as to avoid direct contact between the threaded adjusting member 52 and the upper mold body 21 and cause damage to the upper mold body 21. Specifically, the upper mold mounting table 22 further includes an abutting block 223. The abutting block 223 is arranged on the side of the positioning block 222 facing away from the vertical mounting plate 221, and the top end of the threaded adjusting member 52 is used to abut against the abutting block 223. The abutting block 223 and the positioning block 222 can be fixedly connected by screws. By replacing the abutting blocks 223 of different sizes, the gap between the upper mold assembly 20 and the lower mold assembly 30 can be assisted in adjusting.
[0054] In one embodiment, as shown in Figure 7 A first installation groove 313 is provided on the peripheral side of the lower mold assembly 30. At least part of the installation component 51 is embedded in the first installation groove 313. The first installation groove 313 penetrates upward through the top of the lower mold assembly 30, so that the top end of the threaded adjusting member 52 can extend out of the first installation groove 313 to abut against the upper mold assembly 20. By providing the first installation groove 313 on the peripheral side of the lower mold assembly 30 and embedding at least part of the installation component 51 in the first installation groove 313, the overall structure can be made more compact, and the first installation groove 313 penetrates upward through the top of the lower mold assembly 30, so as to meet the requirement that the top end of the threaded adjusting member 52 extends upward out of the first installation groove 313 to abut against the bottom of the upper mold assembly 20. Specifically, the first installation groove 313 is provided on the lower mold mounting table 31 of the lower mold assembly 30, and the first installation groove 313 penetrates upward through the top of the lower mold mounting table 31.
[0055] In one embodiment, as Figure 8 shown, the threaded adjusting member 52 includes a screw rod portion 521 and a circular ring portion 522. The screw rod portion 521 is threadedly connected to the threaded hole 5141. The top end of the screw rod portion 521 is used to abut against the bottom of the upper die assembly 20. The circular ring portion 522 is disposed around the outer periphery of the screw rod portion 521 and rotates synchronously with the screw rod portion 521. During operation, the circular ring portion 522 can be used as a knob. The user can rotate the circular ring portion 522 to drive the screw rod portion 521 to rotate, so that the threaded portion moves in the vertical direction to adjust the gap between the upper die assembly 20 and the lower die assembly 30, and the operation is very convenient. Specifically, the circular ring portion 522 and the screw rod portion 521 can be an integral structure. In addition, the circular ring portion 522 can be provided with patterns for enhancing the frictional force to facilitate the rotation operation by the user.
[0056] In one embodiment, in combination with Figure 7 and Figure 8 shown, the mounting assembly 51 includes an upper mounting block 511 and a lower mounting block 512. The upper mounting block 511 and the lower mounting block 512 cooperate to form a limiting space 513. The upper mounting block 511 is provided with an upper connecting hole 5111 communicating with the limiting space 513. The lower mounting block 512 is provided with a lower connecting hole 5121 communicating with the limiting space 513.
