Abstract
Description
Technical Field
[0001] This utility model relates to the field of interventional surgical leads, specifically an anti-tangle device for guide wires used in interventional surgery. Background Technology
[0002] Interventional surgery is a minimally invasive medical diagnostic and treatment technique in clinical practice. Guided by imaging equipment (such as X-ray, ultrasound, CT, MRI, etc.), catheters, guidewires, stents and other instruments are introduced into the human body through natural cavities or tiny incisions to diagnose or treat lesions. Its core characteristics are minimal trauma, rapid recovery and precise targeting. It has become an important alternative to traditional open surgery for many diseases, especially in more complex cases where two or three guidewires are needed, which can easily lead to guidewire entanglement.
[0003] Currently, multiple guidewires are typically used in interventional procedures. Normally, after the guidewires are combed out, they are prone to tangling during subsequent use. This makes it difficult to separate and untangle the guidewires easily. Furthermore, some untangling structures are prone to deviation or detachment when untangling the guidewires, and it is not easy to prevent the guidewires from falling off and to limit their movement. Therefore, it is necessary to design a guidewire anti-tangling device for interventional procedures to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a guidewire anti-entanglement device for interventional surgery to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a guidewire anti-entanglement device for interventional surgery, comprising a fixing block for supporting the guidewire, the outer side of the fixing block having multiple grooves for placing the guidewire in an arc-shaped arrangement, a cover plate hinged to one side of the fixing block via a fixing shaft, multiple sets of evenly arranged guide members fixedly installed at the bottom of the cover plate, and a locking member installed at the end of the cover plate, the guide members being used to comb the guidewire to prevent entanglement, and the locking member being used to open and lock the cover plate and the fixing block.
[0006] Preferably, the guide component includes multiple sets of fixing strips fixedly connected to the bottom inner side of the cover plate.

[0021] 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.
[0022] Example 1
[0023] Please refer to Figure 1-5 As shown, this utility model provides a guide wire anti-entanglement device for interventional surgery, including a fixing block 1 for supporting the guide wire. The fixing block 1 has multiple grooves 2 on its outer side for placing the guide wire in an arc-shaped arrangement. A cover plate 4 is hinged to one side of the fixing block 1 through a fixing shaft 3. Multiple sets of evenly arranged guide members are fixedly installed at the bottom of the cover plate 4. A locking member is installed at the end of the cover plate 4. The guide members are used to comb the guide wire to prevent it from entangled. The locking member is used to open and lock the cover plate 4 and the fixing block 1. A through hole 20 for picking up or holding is opened on the other side of the fixing block 1.
[0024] In addition, the through hole 20 facilitates medical staff to move and suspend the fixing block 1. Both sides of the fixing block 1 are arc-shaped, and the cover plate 4 also has an arc-shaped cross section. The cover plate 4 is hinged to the fixing block 1 through the fixing shaft 3 to open and close. Multiple grooves 2 can provide space for multiple guide wires. Multiple grooves 2 correspond one-to-one with the guide components. The locking component can fit and lock the cover plate 4 to the outer edge of the fixing block 1, so that multiple sets of guide components on the inner side of the cover plate 4 can guide multiple guide wires separately, preventing multiple guide wires from getting tangled during use.
[0025] Specifically, the guide component includes multiple sets of fixing strips 5 fixedly connected to the bottom inner side of the cover plate 4. Each set of fixing strips 5 includes two, and a fixing rod 7 for supporting the guide roller 6 is rotatably installed between the two fixing strips 5. The fixing rod 7 is rotatably connected to the guide roller 6. The guide component also includes a support strip 8 laid inside the groove 2. An inlet portion 18 is provided on the outer side of the guide roller 6. A guide groove 19 is provided at the center of the inlet portion 18. A pad strip 9 for protecting the support strip 8 is laid on the surface of the support strip 8.
[0026] In this configuration, two fixed strips 5 are symmetrically arranged in each group. The two fixed strips 5 can drive the guide roller 6 into the groove 2 through the fixed rod 7. The support strip 8 in the groove 2 can support the guide wire. The pad strip 9 on the outside of the support strip 8 can fit with the guide wire. The pad strip 9 can provide wear-resistant protection for the support strip 8, preventing the guide wire from being dragged against the support strip 8 or causing wear and damage to the support strip 8 due to prolonged use. Multiple guide wires enter the groove 2 for guidance. When the guide wire fits with the guide roller 6, it enters the guide groove 19 through the inlet part 18 to prevent the guide wire from shifting or detaching. When the guide wire moves, it can drive the guide roller 6 to rotate outside the fixed rod 7, improving the practicality of separating and guiding multiple guide wires to prevent entanglement.
[0027] More specifically, the locking element includes a movable cavity 10 opened on the inner side of the end of the cover plate 4. A pad 11 is slidably connected to the inner side of the movable cavity 10. A plurality of evenly arranged connecting rods 12 are fixedly connected to one side of the pad 11. A spring 13 is fitted on the outer side of the connecting rod 12. A locking block 14 is fixedly connected to the other side of the pad 11. A locking groove 15 is opened at the other end of the fixed block 1. A connecting strip 16 is fixedly connected to one end of the plurality of connecting rods 12. A limiting part 17 extends from the top of the locking block 14. The limiting part 17 is embedded in the top of the locking groove 15. Both the locking block 14 and the locking groove 15 are right-angled trapezoids. The connecting rod 12 passes through the cover plate 4 and is slidably connected to it.
[0028] Furthermore, the inclined surface of the locking block 14 corresponds to the inclined surface of the locking groove 15. When the cover plate 4 is closed downwards, the fixing block 1 pushes and squeezes the inclined surface of the locking block 14, so that the locking block 14 can enter the movable cavity 10. When the pushing force of the fixing block 1 disappears, multiple springs 13 can squeeze and push the pad 11, so that the pad 11 drives the locking block 14 to be embedded in the locking groove 15 to lock and fix the cover plate 4. The limiting part 17 at the top of the locking block 14 is embedded in the top of the locking groove 15 to increase the stability of fixing the locking block 14. When it is necessary to remove the cover plate 4, the cover plate 4 needs to be pressed down, and then the connecting rod 12 is moved by the connecting strip 16. After the cover plate 4 is fixed, the guide roller 6 limits and guides the guide wire to prevent the guide wire from detaching from the groove 2, thereby improving the convenience and stability of installing the cover plate 4.
[0029] Working principle: First, the guide wire is placed on the pad 9 of the support bar 8 in the groove 2. Then, the cover plate 4 is hinged and rotated through the fixed shaft 3 and locked with the fixed block 1. When the cover plate 4 closes down, the fixed block 1 pushes and squeezes the inclined surface of the locking block 14. The locking block 14 is forced into the movable cavity 10. When the pushing force of the fixed block 1 disappears, multiple springs 13 squeeze and push the pad 11. At this time, the pad 11 drives the locking block 14 to embed into the locking groove 15 to lock and fix the cover plate 4. Alternatively, one end of the guide wire can be directly passed through the groove 2 and the guide roller 6. When the guide wire is moved by force, it can easily enter the guide groove 19 through the guide part 18. When the guide wire moves, it drives the guide roller 6 to rotate outside the fixed rod 7.
