Description

Technical Field

[0001] This utility model belongs to the field of microcatheter tip forming technology, and in particular relates to a microcatheter tip forming tooling. Background Technology

[0002] Microcatheters are core instruments in interventional therapy, neurosurgery and other fields. The shape and precision of their tips, such as curvature, directly determine their passability and surgical safety in narrow channels such as blood vessels and tissues.

[0004] To address the problems existing in the prior art, this utility model provides a microcatheter head forming fixture. Starting the second servo motor causes its output shaft to drive a bidirectional screw to rotate. Due to the reversed threads, the two second sliders on the surface of the bidirectional screw move closer or further apart along the second groove, thereby adjusting the distance between the two fixed posts. The microcatheter can be fitted into the annular groove on the surface of the fixed posts. By adjusting the distance, microcatheters of different diameters can be clamped and fixed, enhancing the stability during the forming process and adapting to the forming needs of microcatheters of different specifications.

[0007] Furthermore, a controller is provided on the surface of the base plate, and the controller is electrically connected to the first servo motor, the second servo motor, the first electric guide rail, the second electric guide rail and the heating lamp respectively through wires.

[0008] Compared with the prior art, the beneficial effects of this utility model are: The second servo motor is started, and its output shaft drives the bidirectional screw to rotate. The two second sliders on the surface of the bidirectional screw move closer or further apart along the second slide groove due to the opposite threads, thereby adjusting the distance between the two fixed posts. The microcatheter can be fitted into the annular groove on the surface of the fixed post. By adjusting the distance, the microcatheter of different diameters can be clamped and fixed, enhancing the stability of the molding process and adapting to the molding needs of microcatheters of different specifications.

[0014] See appendix Figure 1-2As shown, a microcatheter tip forming fixture includes a base plate 1. Multiple first grooves 2 are formed at the top of the base plate 1. A first servo motor 3 is fixedly connected inside the first groove 2. A screw 4 is fixedly connected to the output shaft of the first servo motor 3. A first slider 5 is threadedly connected to the surface of the screw 4 and slidably connected inside the first groove 2. A second groove 6 is formed at the top of the first slider 5. A second servo motor 7 is fixedly connected to the surface of the second slider 9. The output shaft of the second servo motor 7 movably passes through and extends into the second groove 6. A bidirectional screw 8 is fixedly connected to the output shaft of the second servo motor 7. Two second sliders 9 are threadedly connected to the surface of the bidirectional screw 8 and slidably connected inside the second groove 6. A fixing post 10 is movably connected to the top of the second slider 9. An annular groove is formed on the surface of the fixing post 10. A first electric guide rail 11 is fixedly connected to the top of the base plate 1. A fixing frame 12 is provided on the first electric guide rail 11. A second electric guide rail 13 is fixedly connected to the surface of the fixing frame 12. A heating lamp 14 is provided on the second electric guide rail 13.

[0015] The surface of the fixed frame 12 is movably connected with rollers, and the top of the base plate 1 is provided with a rolling groove, with the rollers located inside the rolling groove.

[0016] A controller is provided on the surface of the base plate 1. The controller is electrically connected to the first servo motor 3, the second servo motor 7, the first electric guide rail 11, the second electric guide rail 13 and the heating lamp 14 through wires.

[0017] Working principle: The second servo motor 7 is activated, and its output shaft drives the bidirectional screw 8 to rotate. Due to the reversed threads, the two second sliders 9 on the surface of the bidirectional screw 8 move closer or further apart along the second sliding groove 6, thereby adjusting the distance between the two fixed posts 10. The microcatheter can be fitted into the annular groove on the surface of the fixed post 10. By adjusting the distance, microcatheters of different diameters can be clamped and fixed, enhancing stability during the molding process and adapting to the molding needs of microcatheters of different specifications. The first electric guide rail 11 drives the fixed frame 12 to move, and the second electric guide rail 13 drives the heating lamp 14 to move. Through the coordinated movement of the two sets of electric guide rails, the heating lamp 14 can be precisely positioned directly above the head of the microcatheter to be molded. The domain provides space for precise heating. The heating lamp 14 is activated to heat and soften the tip of the microcatheter on the fixed post 10. At the same time, the tip of the microcatheter is shaped according to the design requirements after being heated. After cooling, it forms a tip shape with the required precision. One or more of the first servo motors 3 are activated, and their output shafts drive the screw 4 to rotate. Since the first slider 5 is threadedly connected to the screw 4 and slides in the first groove 2, the position of the fixed post 10 is adjusted, thereby bending the heated tip of the microcatheter. This allows the tip of the microcatheter to be shaped according to the design requirements after being heated and to form a tip shape with the required precision after cooling. The controller is a PLC controller, which is a common method used by those skilled in the art. The working principle will not be described in detail here.

[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0019] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
