Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary device technology, and in particular relates to a cardiovascular interventional catheter device. Background Technology

[0002] Cardiovascular diseases, such as coronary heart disease, myocardial infarction, and arrhythmias, are among the leading causes of death worldwide. To more effectively diagnose and treat these diseases, advanced technologies and tools are needed, leading to the development of cardiovascular interventional catheter devices to meet the demand for precise diagnosis and minimally invasive treatment of cardiovascular diseases.

[0003] However, existing guidewires experience significant swaying and friction during movement within the catheter, leading to catheter swaying during subsequent interventional procedures. This makes it difficult for doctors to precisely control the catheter tip, resulting in positioning errors and failure to accurately reach the target location. Consequently, it affects subsequent diagnostic and treatment procedures, hinders the accurate delivery of medications or instruments to the lesion, or fails to fully cover the lesion site during procedures such as vasodilation.

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0016] The technical solution of a cardiovascular interventional catheter device provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0017] Reference Figures 1 to 7As shown, this embodiment of the invention provides a cardiovascular interventional catheter device, including a catheter 1 and a guidewire 2. The catheter 1 is provided with a plurality of equally spaced position limiting structures 3, which can rotate within the catheter 1. The guidewire 2 is located within the catheter 1 and slides on the plurality of position limiting structures 3. A sheath 4 and a mounting frame 5 are provided at the end of the catheter 1. The mounting frame 5 is provided with a guidewire moving structure 6 that drives the guidewire 2 to move. The guidewire moving structure 6 is slidably engaged with the mounting frame 5. The mounting frame 5 is provided with a moving adjustment structure 7, which is connected to the guidewire moving structure 6 by transmission.

[0018] During interventional treatment, guidewire 2 slides on multiple position limiting structures 3 within catheter 1 to ensure that guidewire 2 does not wobble during movement, guaranteeing stable movement of guidewire 2. This allows the physician to more accurately guide guidewire 2 to the target position, providing an accurate path for subsequent treatment procedures such as stent placement or embolization, thereby improving treatment outcomes. The stable sliding of guidewire 2 through position limiting structures 3 reduces risks, protects the integrity of blood vessels, and decreases the probability of adverse events such as bleeding and thrombosis caused by vascular damage, thus improving the safety of the procedure.

[0019] When the guidewire 2 moves forward, its position needs to be moved forward. The guidewire 2 will move forward through the guidewire moving structure 6 to make the guidewire 2 move more smoothly. When the guidewire 2 moves, the guidewire moving structure 6 can be adjusted and modified through the guidewire 2 adjustment structure to make the guidewire 2 move more smoothly.

[0020] In this embodiment, each of the position limiting structures 3 includes a rotating ring 31, which is rotatably connected inside the catheter 1. The rotating ring 31 has four equally spaced arc-shaped plates 32. A buffer spring 33 and a buffer damper 34 are provided between the arc-shaped plates 32 and the rotating ring 31. The buffer damper 34 is located inside the buffer spring 33. A moving channel for the guide wire 2 to move is formed between the four arc-shaped plates 32. A hydrogel lubricating film is provided on the side wall of the moving channel. The rotating ring 31 has a plurality of equally spaced rotating beads 35, and the rotating ring 31 is rotatably connected inside the catheter 1 through the plurality of rotating beads 35.

[0021] When guidewire 2 moves, it will sway with catheter 1 due to different positions and channels within the blood vessel. When guidewire 2 moves on the arc-shaped plate 32 of the hydrogel lubricating membrane, it will be very smooth. However, when guidewire 2 rotates or vibrates during movement, it will come into contact with the arc-shaped plate 32. The buffer spring 33 and the buffer damper 34 on the arc-shaped plate 32 will dampen and buffer the swaying and vibration, so that guidewire 2 will not vibrate when moving forward. This ensures the stable movement of guidewire 2, allowing the doctor to guide guidewire 2 to the target position more accurately. This provides an accurate path for subsequent treatment operations, such as stent placement or embolization, thereby improving the treatment effect.

[0022] In this embodiment, the guide wire moving structure 6 includes a moving block 61, with two sliding grooves 62 at each end of the moving block 61. The mounting circular frame 5 is provided with a semi-annular groove 51. The moving block 61 is slidably connected to the semi-annular groove 51 through the two sliding grooves 62. Locking knobs 63 are provided at each end of the moving block 61. A through groove 64 is provided inside the moving block 61.

[0023] During interventional surgery, the moving block 61 can rotate within the semi-annular groove 51 on the mounting frame 5 via two sliding grooves 62. Then, the position of the moving block 61 can be fixed within the semi-annular groove 51 by tightening the locking knob 63. During interventional surgery on the patient, the position of the moving block 61 can be adjusted according to the different surgical environment and the operating position of the medical staff, so that the guidewire 2 can be easily adjusted and moved forward during the intervention.

[0024] In this embodiment, the movable adjustment structure 7 includes a mounting frame 71, an adjustment block 72, an adjustment screw 73, and an adjustment wheel 74. The mounting frame 71 is horizontally disposed in the through groove 64, and the mounting frame 71 is provided with a horizontally disposed adjustment groove 75. The adjustment block 72 is slidably connected in the adjustment groove 75. The adjustment screw 73 is rotatably connected in the mounting frame 71, and the adjustment block 72 and the adjustment screw 73 are threadedly connected. The adjustment wheel 74 is rotatably connected to the adjustment block 72.

[0025] When moving different types of guide wires 2, causing the moving guide wheel 690 to come into contact with the guide wire 2, rotating the adjusting screw 73 will cause the adjusting block 72 to move horizontally within the adjusting groove 75 in the mounting frame 71. The movement of the adjusting block 72 will cause the adjusting wheel 74 to move. When the moving guide wheel 690 moves upward, the adjusting belt 691 will be in a slack state. At this time, the adjusting belt 691 needs to be adjusted to make it taut. The horizontal movement of the adjusting block 72 within the adjusting groove 75 will cause the adjusting wheel 74 to move. Thus, when the guide wire 2 moves forward, the moving guide wheel 690 comes into contact with the guide wire 2. When the moving guide wheel 690 rotates, it can move the guide wire 2 forward.

[0026] In this embodiment, the guide wire moving structure 6 includes a rotating shaft 65, which is horizontally rotatably connected in a through groove 64. A turning wheel 66 is provided on the rotating shaft 65, and an upper rotating wheel 67 is provided beside the turning wheel 66 on the rotating shaft 65. A vertically arranged mounting part is provided in the through groove 64, and a rotating shaft 68 is rotatably connected on the mounting part. A lower rotating wheel 69 is provided at one end of the rotating shaft 68, and a moving guide wheel 690 is provided at the other end of the rotating shaft 68. An adjusting belt 691 is provided between the upper rotating wheel 67, the lower rotating wheel 69, and the adjusting wheel 74.

[0027] During interventional treatment, when the guidewire 2 is moved forward, the actuating wheel 66 is rotated to make the rotating shaft 65 rotate within the through groove 64, thereby driving the upper rotating wheel 67 to rotate. By adjusting the belt 691, the lower rotating wheel 69 is driven to rotate. The rotation of the lower rotating wheel 69 will drive the rotating shaft 68 to rotate, thereby driving the moving guide wheel 690 to rotate, thus moving the guidewire 2 forward within the catheter 1 to perform interventional treatment.

[0028] In this embodiment, the mounting part includes a mounting plate 76 and a movable plate 77. The mounting plate 76 is fixedly connected in the through groove 64, and the movable plate 77 is slidably connected to the mounting plate 76. Fixed knobs 78 are respectively provided at both ends of the movable plate 77.

[0029] When the position of the movable guide wheel 690 is adjusted to make contact with the guide wire 2, the movable plate 77 moves up and down on the mounting plate 76. When the position of the movable plate 77 moves downward, it will drive the movable guide wheel 690 to move onto the guide wire 2. Then, tighten the fixing knob 78 to fix the position of the movable plate 77 on the mounting plate 76, so that the movable guide wheel 690 abuts against the guide wire 2, so that the subsequent lead wire can move upward for interventional treatment.

[0030] In this embodiment, the movable guide wheel 690 is provided with an anti-slip layer. The anti-slip layer ensures that when the movable guide wheel 690 drives the guide wire 2 forward, there is friction between the movable guide wheel 690 and the guide wire 2, so as to smoothly drive the guide wire 2 forward.

[0031] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
