Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an adjustable guide rod disassembly tool. Background Technology

[0002] In the medical industry, guidewires are widely used in interventional surgeries and other medical scenarios. For example, when dealing with tortuous, narrow, or bifurcated blood vessels, guidewires need to be able to adapt to complex intraluminal environments. This requires guidewires to have bending adjustment functions. Adjustable guidewire assemblies achieve a wide range of adjustment of the guidewire tip angle through specific structural designs. For these types of adjustable guidewire assemblies, corresponding disassembly tools are required for installation, maintenance, and replacement to facilitate operation and improve surgical efficiency and safety.

[0003] The adjustable guide rod disassembly tool is a specialized tool designed for efficient and precise disassembly of guide rods. With its adjustable structure, it can adapt to guide rods of various specifications and is widely used in textiles, medical devices, precision manufacturing and other fields. The core feature of the adjustable guide rod disassembly tool is its multi-scenario adaptability. The tool can flexibly adjust its size and angle through thread adjustment, slot positioning or telescopic structure, and can be compatible with guide rods of different diameters and shapes.

[0004] Currently, most adjustable guide rod disassembly tools are integral structures. Without the addition of directional adjustment and protection functions, they will result in limited operating space, poor adaptability, low force transmission efficiency, damage to the guide rod and surrounding components, and increased maintenance costs. Therefore, an adjustable guide rod disassembly tool is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4 This utility model provides an embodiment of an adjustable guide rod disassembly tool, comprising a support column 2 made of high-strength alloy steel, a threaded rod 3 rotatably connected inside the support column 2, the threaded rod 3 being made of high-hardness tempered steel, a power device 4 fixedly connected to the top of the threaded rod 3, the power device 4 being fixedly connected to the top of the support column 2, a fixed seat 5 threadedly connected to the outside of the threaded rod 3, a main arm 7 rotatably connected to one end of the fixed seat 5, a drive device 6 fixedly connected to the side of the fixed seat 5 away from the main arm 7, a secondary arm 9 rotatably connected to one side of the main arm 7, and a drive device 8 fixedly connected to the end of the main arm 7 away from the secondary arm 9. The threaded rod 3 converts the rotational motion of the power device 4 into the linear motion of the fixed seat 5 through threaded transmission, realizing the height adjustment of the main arm 7 and the secondary arm 9. The fixed seat 5 is slidably connected inside the support column 2, and a base 1 is fixedly connected to the bottom of the support column 2. The base 1 and the support column 2 provide stable support as a whole, and its internal slide rail restricts the fixed seat 5 to slide only in the vertical direction to avoid displacement.

[0033] Reference Figures 1-4A hydraulic rod 14 is fixedly connected inside the auxiliary boom 9. The hydraulic rod 14 uses a high-strength seamless steel pipe as its cylinder body, and the internal piston and piston rod are made of wear-resistant alloy material. A sliding block 10 is fixedly connected to the output end of the hydraulic rod 14. The hydraulic rod 14 drives the sliding block 10 to slide axially inside the auxiliary boom 9 through its telescopic movement, providing a power source for the opening and closing of the grab hook 12. Its hydraulic transmission characteristics can achieve a smooth output of force. A rotating fixed seat 15 is fixedly connected to the side of the sliding block 10 away from the hydraulic rod 14. Three pull rods rotatably connect to the side of the rotating fixed seat 15 away from the sliding block 10. A grab hook 12 is rotatably connected to the end of the three pull rods 11 away from the sliding block 10. Flexible rubber sleeves 13 are provided on the opposite sides of the three grab hooks 12. The flexible rubber sleeves 13 cover the clamping surface of the grab hook 12. On the one hand, they fill the gap between the grab hook 12 and the guide rod through their own elasticity, thereby enhancing the clamping force. The sliding block 10 is slidably connected inside the auxiliary boom 9. The grab hook 12 is rotatably connected to the end of the auxiliary boom 9 away from the hydraulic rod 14. The rotating fixed seat 15 is slidably connected inside the auxiliary arm 9. The slide rail inside the auxiliary arm 9 provides guidance for the sliding block 10 and the rotating fixed seat 15, restricting their movement to only along the axial direction, avoiding misalignment of the grab hook 12 caused by offset, and ensuring the motion accuracy of the overall structure.

[0034] Working Principle: When using the adjustable guide bar disassembly tool, first start the power unit 4, then the output shaft drives the threaded rod 3 to rotate. The surface of the threaded rod 3 is machined with a high-precision trapezoidal thread, which cooperates with the threaded sleeve inside the fixed seat 5 to form a helical transmission pair. Since the fixed seat 5 is constrained by the linear slide rail on the inner wall of the support column 2, the rotational motion is converted into linear displacement of the fixed seat 5 along the axis of the support column 2. The drive unit 6 outputs torque, which drives the connecting shaft between the main arm 7 and the fixed seat 5 to rotate. The drive unit 8 acts on the connecting joint between the main arm 7 and the auxiliary arm 9, which can precisely adjust the vertical height of the main arm 7, the auxiliary arm 9 and the end gripper hook 12. It can adapt to the complex tilt posture of the guide bar and the installation height of the guide bar in different equipment. This action adapts to the horizontal offset installation scenario of the guide bar, ensuring that the gripper hook 12 can approach the target from different directions and angles.

[0035] Hydraulic rod 14 serves as the power source for hook 12. Its cylinder is fixed within the inner cavity of auxiliary arm 9. The piston rod of hydraulic rod 14 is fixedly connected to sliding block 10, allowing for precise control of thrust and pull. When hydraulic rod 14 extends or retracts, sliding block 10 drives rotating fixed seat 15 to slide along the slide rail inside auxiliary arm 9, causing pull rod 11 to move synchronously. Rotating fixed seat 15 is connected to hook 12 via three-link pull rod 11. Utilizing the principle of planar linkage transmission, the linear motion of sliding block 10 is converted into the synchronous opening and closing action of hook 12. Hook 12 closes when hydraulic rod 14 retracts and opens when hydraulic rod 14 extends. The flexible rubber sleeve 13 inside hook 12 is made of medical-grade silicone, possessing high elasticity and low friction characteristics. When hook 12 closes, the rubber sleeve first contacts the surface of guide rod, absorbing clamping impact through elastic deformation, avoiding scratches and deformation caused by hard metal contact. Simultaneously, the rubber sleeve increases the contact area, using friction to improve clamping stability.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
