Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical guidewire technology, and in particular to a medical guidewire tip bending and forming device. Background Technology
[0002] Guide wires, also known as guide wires or guide lines, are widely used in the medical field, especially in interventional surgery, to help catheters enter blood vessels and other cavities and guide them smoothly to the lesion.
[0003] Medical guidewires, as indispensable tools in modern interventional surgery, are crucial to the accuracy and success rate of the procedure due to the precision of their design and manufacturing. The design of the guidewire tip is particularly critical, as it directly determines the guidewire's guiding ability and maneuverability within blood vessels, catheters, or other confined spaces. The guidewire tip typically has a hooked shape. Before bending the guidewire tip into this hooked shape, it usually needs to be flattened to prevent it from springing back and deforming during the bending process. Currently, most medical guidewire tip bending on the market relies on manual operation. This method is not only inefficient but also makes it difficult to ensure consistent pressure on each guidewire during compression, potentially affecting the accuracy of compression. Furthermore, manual compression can cause unnecessary damage to the guidewire material. Utility Model Content
[0004] To address the aforementioned deficiencies, the purpose of this invention is to propose a medical guidewire tip bending and forming device. This device uses an extrusion section to extrude the guidewire tip and a limiting member to limit the position of the guidewire tip, ensuring that the extrusion force on each guidewire tip is consistent and that the extrusion position of each guidewire tip is consistent.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A medical guide wire tip bending forming device includes a material support block, an extrusion section, a limiting member, and a discharge member. The material support block is disposed at one end of the extrusion section, and the limiting member is disposed at the other end of the extrusion section. The guide wire is placed on top of the material support block and pushed to the extrusion end of the extrusion section for extrusion. When the guide wire is pushed into the extrusion section, the limiting end of the limiting member moves to one end of the extrusion end of the extrusion section to limit the position of the guide wire. The discharge member is disposed on one side of the limiting member. After extrusion is completed, the limiting end of the limiting member retracts from one end of the extrusion end of the extrusion section, and the discharge member moves to one end of the extrusion end of the extrusion section to pull the extruded guide wire out of the extrusion section.

[0025] The following is combined Figures 1 to 5 This invention describes a medical guide wire tip bending and forming device according to an embodiment of the present invention.
[0026] A medical guide wire tip bending forming device includes a material support block 1, an extrusion section 2, a limiting member 3, and a discharge member 4. The material support block 1 is disposed at one end of the extrusion section 2, and the limiting member 3 is disposed at the other end of the extrusion section 2. The guide wire is placed on the top of the material support block 1 and pushed to the extrusion end of the extrusion section 2 for extrusion. When the guide wire is pushed into the extrusion section 2, the limiting end of the limiting member 3 moves to the end of the extrusion end of the extrusion section 2 to limit the position of the guide wire. The discharge member 4 is disposed on one side of the limiting member 3. After extrusion is completed, the limiting end of the limiting member 3 exits from the end of the extrusion end of the extrusion section 2, and the discharge member 4 moves to the end of the extrusion end of the extrusion section 2 to pull the extruded guide wire out of the extrusion section 2.
[0027] A medical guidewire tip bending and forming device is provided for flattening guidewire tips for bending. The guidewire is placed on top of a support block 1, and then the tip of the guidewire is pushed into an extrusion section 2 for extrusion. The extruded guidewire is then carried out by a discharge member 4, thus completing the flattening of the guidewire tip. Using the extrusion section 2 to flatten the guidewire tip ensures that each guidewire tip is flattened to a uniform degree and guarantees the extrusion force, thus ensuring the accuracy of the flattened guidewire tip. A limiting member 3 is located at the other end of the extrusion section 2 to limit the position of the guidewire tip for proper extrusion.
[0028] Specifically, the extrusion section 2 includes a lower pressure film 21, an upper pressure die 22, a moving member 23, and a first telescopic mechanism 24. The upper pressure die 22 is installed directly above the lower pressure film 21. The driving end of the first telescopic mechanism 24 is connected to the upper pressure die 22 and drives the upper pressure die 22 to cooperate with the lower pressure film 21 to extrude the guide wire end. The lower pressure film 21 is installed on the moving end of the moving member 23, and the moving member 23 drives the lower pressure film 21 to move left and right. The guide wire end extends between the lower pressure film 21 and the upper pressure die 22. The first telescopic mechanism 24 drives the upper pressure die 22 to push towards the lower pressure film 21, so that the lower pressure film 21 and the upper pressure die 22 cooperate to extrude the guide wire end. After the guide wire end is extruded, the first telescopic mechanism 24 drives the upper pressure die 22 to move upward. When the guide wire end is deeply inserted between the lower pressure film 21 and the upper pressure die 22, the guide wire end is located at the top surface of the lower pressure film 21, which facilitates extrusion. The pressure membrane 21 is installed on the moving end of the moving part 23. The moving part 23 drives the pressure membrane 21 to move left and right, and the position of the pressure membrane 21 can be moved according to the position of the extrusion guide wire.
[0029] Specifically, the extrusion end of the upper die 22 is cylindrical, and the extrusion end of the lower die 21 is a circular groove. The extrusion ends of the upper die 22 and the lower die 21 are configured to cooperate with each other. The cylindrical shape of the upper die 22 and the circular groove shape of the lower die 21 can extrude the guide wire tip into a flat cylindrical shape, which allows the internal stress to be better dissipated when the guide wire tip is bent later, making it less prone to reverting to its original shape after bending.
[0030] Specifically, the moving component 23 includes a first slide rail 231, a first slider 232, and a second telescopic mechanism 233. The first slider 232 is slidably mounted on the upper end of the first slide rail 231, and the driving end of the second telescopic mechanism 233 is connected to the first slider 232 and drives the first slider 232 to move along the first slide rail 231. The pressure film 21 is mounted on top of the first slider 232. Depending on the specific position of the extrusion guide wire end, the second telescopic mechanism 233 drives the first slider 232 to move the pressure film 21 to match the position of the guide wire end for extrusion.
[0031] Specifically, the top of the first telescopic machine 24 is provided with a second slide rail 5 and a second slider 6; the top of the first telescopic machine 24 is connected to the bottom of the second slider 6, and the second slider slides at the second slide rail 5. The first telescopic machine 24 can move the position of the upper pressure mold 22 according to the position of the lower pressure film 21, so that the position of the upper pressure mold 22 matches the position of the lower pressure film 21.
[0032] Specifically, the discharge component 4 includes an upper rolling rod 41, a lower rolling rod 42, a side plate 43, a third telescopic mechanism 44, and a motor 45. One end of the upper rolling rod 41 and one end of the lower rolling rod 42 are rotatably mounted on the side plate 43. The upper rolling rod 41 is located directly above the lower rolling rod 42, and the positions of the upper rolling rod 41 and the lower rolling rod 42 are matched. The drive end of the motor 45 is connected to one end of the upper rolling rod 41 or one end of the lower rolling rod 42. The drive end of the third telescopic mechanism 44 is connected to the side plate 43 and pulls the side plate 43 to move. After the guide wire head is extruded, the drive side plate 43 of the third telescopic mechanism 44 pushes the upper rolling rod 41 and the lower rolling rod 42 to move, so that the position between the upper rolling rod 41 and the lower rolling rod 42 is engaged with the guide wire head. Then, the motor 45 drives one end of the upper rolling rod 41 or the lower rolling rod 42 to rotate, so that the upper rolling rod 41 and the lower rolling rod 42 cooperate to clamp and move the guide wire out of the extrusion section 2.
[0033] Specifically, outer casings 7 are installed on the outer sides of the upper roller 41 and the lower roller 42. This prevents other debris from falling into the upper roller 41 and the lower roller 42, ensuring their normal operation.
[0034] Specifically, the limiting component 3 includes a baffle 31 and a fourth telescopic mechanism 32. One end of the baffle 31 is installed on the drive end of the fourth telescopic mechanism 32, which drives the baffle 31 to move back and forth. The baffle 31 is used to hold the guide wire head end in position, so that each guide wire is squeezed in the same position. When preparing to squeeze the guide wire head end, the fourth telescopic mechanism 32 drives the baffle 31 to push out. When the guide wire is pulled out, the fourth telescopic mechanism 32 pulls the baffle 31 back.
[0035] To further explain, a feeding groove is provided on the top of the material receiving block 1, and the position of the feeding groove is matched with the position of the extrusion end of the extrusion section 2. The feeding groove facilitates the accurate placement of the guide wire into the extrusion section 2, and the feeding groove plays a guiding role.
