Description

Technical Field

[0001] This utility model relates to the field of guidewire shaping tools, specifically to an interventional guidewire shaping device. Background Technology

[0002] In interventional procedures, guidewire shaping is one of the key steps to surgical success. Guidewire shaping needs to be adjusted according to the anatomy of the target vessel, especially in complex bifurcation lesions; proper tip shaping can significantly improve the success rate. With the increasing prevalence of interventional procedures and the rise in complex cases, higher demands are placed on the precision and ease of guidewire shaping techniques. Currently, guidewire shaping mainly relies on the operator's experience, as shown in the attached... Figure 1 As shown, guide pins or shaping pins of different thicknesses need to be used to press down the guide wire tip (the black line indicates the guide wire, and the circle indicates the shaping tool). Then, the guide wire tip is manually bent and shaped. There is a lack of tools with high shaping accuracy and easier operation to support the above operation. The length of the bent guide wire cannot be obtained intuitively, and there are no suitable tools to maintain the short-term shaping of the bent guide wire. Utility Model Content

[0003] The purpose of this utility model is to at least partially solve one of the technical problems in related technologies. In view of this, an interventional guidewire shaping device is provided, comprising: a platform; a shaping rod, which is vertically and movably mounted on the platform, and the shaping rod has multiple shaping segments of different diameters along its axial direction; a guidewire fixing component, which is magnetically fixed to the platform, with one end of the guidewire fixing component facing the shaping rod, and the guidewire fixing component is provided with a tension adjuster for fixing the guidewire; and a guidewire bending component, which is magnetically fixed to the platform, and the guidewire bending component is provided with a transparent straight tube for inserting the guidewire tip, and a straight ruler extending in the same direction as the transparent straight tube is fixed to the side of the transparent straight tube, and the straight ruler is provided with length markings.

[0004] Compared with existing technologies, the technical advantages of this solution are as follows: By setting up a platform as a stable support, the entire guidewire shaping process can be smoothly supported. The shaping rod, which is movably installed on the platform, is the core shaping component. Controlling the raising and lowering of the shaping rod on the platform exposes the shaping section of the required diameter. In practice, the guidewire is controlled to bend and shape as needed, passing around the shaping section of the corresponding diameter to match the curvature and bending length of the target vascular anatomy. The guidewire is generally long and easily bent and deformed. The guidewire fixation component is used to fix the guidewire body to prevent manual contact contamination or deformation caused by applied force. After the guidewire body is fixed, the guidewire bending component is controlled to fit the guidewire tip of the required length, and then passes around the shaping section of the shaping rod to the expected curvature to complete the shaping operation. The entire process does not require manual contact with the guidewire. The transparent straight tube on the guidewire bending component allows for easy and intuitive observation of the guidewire tip to be bent. Combined with a straight ruler and length markings, the length information of the guidewire tip inserted into the transparent straight tube can be accurately obtained. In addition, both the guide wire fixing component and the guide wire bending component are magnetically fixed to the platform, making position adjustment convenient. The entire shaping tool is easy to operate, the length of the guide wire bending section is visible and controllable, and the shaped guide wire tip can maintain its shape under the constraint of the guide wire fixing component and the guide wire bending component.

[0005] In one embodiment of this utility model, the platform has a through hole in the middle, and the bottom side of the platform has a threaded tube extending downward perpendicularly to the platform and coaxially arranged with the through hole; the bottom end of the shaping rod has a threaded section, and is adapted to be connected to the threaded tube through the threaded section.

[0006] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: There are many ways to fix the shaping rod on the platform. In this example, a stable and practical threaded fixing method is used. The through hole in the middle of the platform facilitates the shaping rod to move up and down. While the threaded tube constrains the up and down movement of the shaping rod, it also allows the threaded section to stay stably after the height position is adjusted.

[0007] In one embodiment of this utility model, the top end of the shaping rod is fixed with an adjustment handle suitable for hand operation.

[0008] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the guide wire is generally thinner, and the shaping rod that is adapted to the shaping guide wire is also relatively thinner. It is very inconvenient to operate the shaping rod to move it up and down by directly twisting the top of the shaping rod. By adapting and installing a larger size adjustment handle, the ease of use is good and the adjustment efficiency is high.

[0009] In one embodiment of this utility model, a straight groove is provided on the top surface of the guide wire fixing member, and the straight groove passes through the guide wire fixing member to fix the guide wire.

[0010] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the guide wire is a slender product, and by designing a straight groove to assist in constraining and fixing the guide wire, the guide wire can be kept straight, and the part of the guide wire that needs to be bent and shaped at the front end can extend out of the straight groove.

[0011] In one embodiment of this utility model, the tension adjuster includes an adjustable bolt and an elastic clip. The adjustable bolt is threaded onto the top surface of the guide wire fixing member, and the elastic clip is fixed onto the adjustable bolt. At least two tension adjusters are provided and are evenly distributed along the extension direction of the guide wire.

[0012] Compared with existing technologies, the technical advantages of this solution are as follows: The adjustable bolt, in conjunction with the elastic clamp, adjusts the tightness of the guide wire on the guide wire fixing component. The adjustable bolt is threaded onto the guide wire fixing component, and the raising or lowering of the elastic clamp is controlled by rotating it in either direction. The elastic clamp itself has strong elastic clamping force; lifting and lowering the elastic clamp completes the elastic downward clamping of the guide wire. The operation is simple, and the fixation effect on the guide wire is stable. By designing and installing multiple tension adjusters, multi-point fixation of the slender guide wire can be achieved, preventing the guide wire from loosening or shifting during the shaping process.

[0013] In one embodiment of this utility model, the guide wire fixing member is provided with a first slot, and a first magnetic block is fixed in the first slot.

[0014] In one embodiment of this utility model, the guide wire bending member is provided with a second slot, and a second magnetic block is fixed in the second slot.

[0015] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by designing the first slot and the second slot on the guide wire fixing component and the guide wire bending component respectively, the first magnetic block and the second magnetic block of the magnetic components can be detached and quickly installed. The platform surface is made of a material that can be magnetically attracted to the magnetic blocks. Through the magnetic attraction characteristics, the guide wire fixing component and the guide wire bending component can be efficiently positioned and fixed after adjustment.

[0016] In one embodiment of this utility model, a disc-shaped angle measuring mark is provided on the top surface of the platform, and the angle measuring mark is coaxial with the shaping rod.

[0017] Among them, the angle measurement mark is similar to a protractor, with angle lines and angle numerical marks, which can help operators intuitively estimate the guide wire bending angle.

[0018] In one embodiment of this utility model, the shaping section has three parts on the shaping rod: a coarse needle section, a fine needle section, and an ultra-fine needle section. Adjacent shaping sections are smoothly connected by a tapered connecting section with a variable diameter.

[0019] The diameters of the coarse needle segment, fine needle segment, and ultra-fine needle segment decrease from high to low, and the curvature of the guidewire after shaping also gradually decreases. In other feasible designs, diameter data can be marked on the shaping segment of the shaping rod to facilitate operators to intuitively select the required shaping segment.

[0020] In one embodiment of this utility model, multiple base columns are vertically arranged at the bottom of the platform, and the base columns are evenly spaced along the circumference of the platform. The evenly distributed design of multiple base columns provides stable support for the bottom of the platform and can raise the height of the platform, so that the shaping rod has a suitable downward movement space relative to the platform.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0031] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] [First Embodiment]

[0033] Please see Figure 1 , Figure 2 As shown, this utility model provides an interventional guidewire shaping device, including: a platform 100; a shaping rod 200, which is vertically and movably installed on the platform 100, and has multiple shaping segments 201 of different diameters along the axial direction of the shaping rod 200; a guidewire fixing member 300, which is magnetically fixed on the platform 100, and one end of the guidewire fixing member 300 faces the shaping rod 200, and the guidewire fixing member 300 is provided with a tension adjuster 500 for fixing the guidewire 400; and a guidewire bending member 600, which is magnetically fixed on the platform 100, and has a transparent straight tube 601 for inserting the head end of the guidewire 400, and a straight ruler 602 extending in the same direction as the transparent straight tube 601 is fixed to the side of the transparent straight tube 601, and the straight ruler 602 is provided with a length mark.

[0034] By setting the stage 100 as a stable support platform, the entire guidewire shaping process can be smoothly supported. The shaping rod 200, which is movably installed on the stage 100, is the core shaping component. Controlling the raising and lowering of the shaping rod 200 on the stage 100 can expose the shaping section 201 of the required diameter. In practice, the guidewire 400 is controlled to bend and shape by passing around the shaping section 201 of the corresponding diameter as needed to match the curvature and bending length of the target vascular anatomy. The guidewire 400 is generally long and easy to bend and deform. The guidewire fixing component 300 is used to fix the guidewire body to avoid manual contact contamination or deformation caused by applied force. After the guidewire body is fixed, the guidewire bending component 600 is controlled to fit into the guidewire tip of the required length, and then passes around the shaping section 201 of the shaping rod 200 to the expected curvature to complete the shaping operation. The entire process does not require manual contact with the guidewire. The transparent straight tube 601 on the guide wire bending component 600 allows for easy and intuitive observation of the guide wire tip to be bent. Combined with the straight ruler 602 and length markers, the length information of the guide wire tip inserted into the transparent straight tube 601 can be accurately obtained. Furthermore, both the guide wire fixing component 300 and the guide wire bending component 600 are magnetically fixed to the stage 100, facilitating easy position adjustment. The entire shaping tool is simple to operate; the length of the bent guide wire section is visually controllable, and the shaped guide wire tip can maintain its shape under the constraint of the guide wire fixing component 300 and the guide wire bending component 600.

[0035] [Second Embodiment]

[0036] Based on the first embodiment, as shown in the figure, the platform 100 has a through hole 101 in the middle, and the bottom side of the platform 100 has a threaded tube 102 that extends downward perpendicularly to the platform 100 and is coaxially arranged with the through hole 101; the bottom end of the shaping rod 200 has a threaded section 202, and is adapted to be connected to the threaded tube 102 through the threaded section 202.

[0037] There are many ways to fix the shaping rod 200 on the platform. In this example, a stable and practical threaded fixing method is used. The through hole 101 in the middle of the platform 100 allows the shaping rod 200 to pass through and move up and down. The threaded tube 102 not only restricts the up and down movement of the shaping rod 200, but also allows the threaded section 202 to stay stably after the height position is adjusted.

[0039] Based on the first embodiment, as shown in the figure, an adjustment handle 203 suitable for hand operation is fixed to the top of the shaping rod 200.

[0040] The guide wire 400 is generally thinner, and the shaping rod 200 that is adapted to the shaping guide wire is also relatively thin. It is very inconvenient to operate the shaping rod 200 up and down by directly twisting the top of the shaping rod. By adapting and installing a larger adjusting handle 203, it is easier to use and has higher adjustment efficiency.

[0041] [Fourth Embodiment]

[0042] Based on the first embodiment, as shown in the figure, a straight groove 301 is provided on the top surface of the guide wire fixing member 300. The straight groove 301 passes through the guide wire fixing member 300 to fix the guide wire 600.

[0043] The guide wire 400 is a slender product. The guide wire 400 is fixed by the straight groove 301 to keep it straight. The part of the guide wire 400 that needs to be bent and shaped can extend out of the straight groove 301.

[0046] The adjustable bolt 501, in conjunction with the elastic clamp 502, adjusts the tightness of the guide wire 400 on the guide wire fixing member 300. The adjustable bolt 501 is threaded onto the guide wire fixing member 300, and its forward and reverse rotation controls the raising or lowering of the elastic clamp 502. The elastic clamp 502 itself possesses strong elastic clamping force; lifting and lowering the elastic clamp 502 completes the elastic downward clamping of the guide wire 400. The operation is simple, and the fixation effect on the guide wire 400 is stable. By designing and installing multiple tension adjusters 500, multi-point fixation of the slender guide wire can be achieved, preventing the guide wire from loosening or shifting during the shaping process.

The platform 100 is made of a material that can magnetically attract the magnetic blocks. Through the magnetic attraction characteristics, the guide wire fixing component 300 and the guide wire bending component 600 can be efficiently positioned and fixed after adjustment.
