[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a medical urological fiber optic guidewire fixing device, comprising a base plate 1, a protrusion 5 on the left side of the base plate 1, and a slot 4 on the right side of the base plate 1. The inner wall of the slot 4 has a groove 6. Adjacent sets of the protrusion 5 on the left side and the slot 4 on the right side of the base plate 1 cooperate through friction, the groove 6, and a limiting plate 42, allowing them to be spliced ​​together according to actual needs, thereby improving the practicality of the device. A rotating column 2 is rotatably connected to the upper inner wall of the base plate 1. Multiple sets of rotating columns 2 are provided; rotating one set of rotating columns 2... The meshing gear 33 drives the adjacent set of rotating columns 2 to rotate synchronously, thereby causing the two sets of rotating columns 2 to drive the fixing components to clamp and fix the guide wire. The bottom inner wall of the base plate 1 is inserted with the mounting part 7 for mounting the components and fixing the device on the fabric, so as to facilitate quick fixation by the doctor during use, thereby improving the convenience of device installation. A fixing mechanism is provided on the outside of the rotating column 2. The fixing mechanism includes a fixing component and a limiting component. The fixing component includes a fixing part 31, which is located on the outside of the rotating column 2.

[0032] Furthermore, the fixing member 31 is configured with a compression groove in the middle and is made of rubber. The compression groove can limit and fix the guide wire, while the rubber material can reduce compression damage to the guide wire and increase the friction with the guide wire, thereby improving the fixation effect. Multiple sets of fixing members 31 are provided, allowing multiple sets of guide wires to be fixed from multiple positions. A limiting post 32 is fixedly connected to one side of two adjacent sets of fixing members 31 to separate and fix different guide wires, making it easier for medical staff to identify them and improving the fixation effect. The improved recognizability after fixation enhances the doctor's work efficiency. Multiple sets of limiting posts 32, made of rubber, separate and fix different guidewires, preventing them from tangling or interfering with each other. This also reduces damage to the guidewires and extends their service life. Gears 33 are fixedly connected to the bottom of the rotating post 2. Multiple sets of gears 33 are provided, with adjacent sets meshing with each other. When one set of rotating posts 2 rotates, it transmits power to the adjacent rotating posts 2, ensuring that multiple sets of rotating posts 2 can move synchronously and achieve coordinated fixation of the guidewires.

[0033] Reference Figure 2 and Figure 3The limiting assembly includes a limiting plate 42, which is slidably connected to the inner wall of the base plate 1. It cooperates with a compression spring 43 and a movable plate 44 to insert into the inner wall of a slot 6 on an adjacent set of base plates 1, thereby limiting the movement of two adjacent sets of base plates 1. A movable plate 44 is slidably connected to the right side of the inner wall of the base plate 1 near the limiting plate 42. The elastic force of the compression spring 43 allows the movable plate 44 to be stably inserted into the inner wall of the limiting hole 41. The right side of the movable plate 44 and the left side of the limiting plate 42 are set as arc surfaces, facilitating easy insertion from the limiting hole 41. 1. The inner wall of the slot 6 slides out. The lower outer side of the rotating column 2 is provided with a limit hole 41. Multiple sets of limit holes are provided. By cooperating with the moving plate 44, the rotating column 2 can be automatically limited, thereby fixing the guide wire. The right side of the moving plate 44 is inserted into the inner wall of the limit hole 41. The right side of the limit plate 42 and the left side of the moving plate 44 are elastically connected by a compression spring 43. One end of the limit plate 42 is fixedly connected to the right side of the limit plate 42, and the other end is fixedly connected to the left side of the moving plate 44, providing elasticity for the limit plate 42 and the moving plate 44 to maintain the stability of their insertion.

[0034] Reference Figure 1 and Figure 3 The bottom of the base plate 1 is provided with an installation component, which includes a limiting strip 72. The limiting strip 72 is slidably connected to the inner wall of the base plate 1 and can be inserted into the inner wall of the limiting groove 71 opened on the outer side of the upper column of the mounting component 7. By cooperating with the limiting groove 71, the mounting component 7 can be fixed or released, thereby completing the installation or removal of the device on the surface of fabric, etc. A push rod 74 is fixedly connected to the front side of the limiting strip 72, which is a component for operating the movement of the limiting strip 72. The doctor controls the insertion relationship between the limiting strip 72 and the limiting groove 71 by pressing the push rod 74. The push rod 74 slides on the inner wall of the base plate 1. The upper part of the mounting component 7 is provided with a column, which is cone-shaped and can pierce the fabric. The outer side of the column is provided with a limiting groove 71, which is provided in multiple sets. It cooperates with the limiting strip 72 to fix the mounting component 7. The outer side of the limiting strip 72 is inserted into the inner wall of the limiting groove 71.

[0035] Furthermore, the rear side of the limiting strip 72 is elastically connected to the base plate 1 via a return spring 73. One end of the return spring 73 is fixedly connected to the inner wall of the base plate 1, and the other end of the return spring 73 is fixedly connected to the rear side of the limiting strip 72. Multiple sets of return springs 73 are provided. After the push rod 74 is pressed, they provide a return force to the limiting strip 72, and at the same time, they can stably insert the limiting strip 72 into the inner wall of the limiting groove 71, which improves the stability of the installation of the mounting component 7. Multiple sets of mounting components are provided, and the multiple sets of mounting components are respectively set on the front and rear sides of the base plate 1, which can improve the stability of the mounting component 7.

[0036] Working principle: When using the light guide wire in the urology department, first align the column of the mounting piece 7 with the fabric and press it to pierce the fabric. Then insert the column into the inner wall of the base plate 1, press down the two sets of levers 74, and drive the limiting strip 72 to slide. The column of the mounting piece 7 is inserted into the inner wall of the limiting groove 71. Then release the levers 74. The elastic force of the return spring 73 drives the limiting strip 72 to insert into the inner wall of the limiting groove 71, fixing the mounting piece 7. This installs the device on the fabric, enhancing the stability of the mounting piece 7 and ensuring that the device will not loosen during use.

[0037] When it is necessary to fix the guide wire, a set of rotating columns 2 are rotated. Since the gears 33 at the bottom of the rotating columns 2 mesh with each other, the rotating columns 2 will drive the adjacent rotating columns 2 to rotate synchronously. As the rotating columns 2 rotate, the guide wire is placed in the compression groove of the fixing member 31. The rubber fixing member 31 can not only limit the guide wire through the compression groove and reduce the compression damage to the guide wire, but also increase the friction between it and the guide wire, thereby effectively fixing the guide wire. In addition, the limiting column 32 between two adjacent sets of fixing members 31 can separate and fix different guide wires to prevent the guide wires from getting tangled together. The limiting plate 42, compression spring 43 and moving plate 44 in the limiting assembly cooperate to automatically limit the rotating columns 2 through the action of the limiting hole 41 during the rotation of the rotating columns 2, further ensuring the stability of the guide wire fixing.

[0038] When it is necessary to extend the length of the device or change the layout, the protrusion 5 on one base plate 1 is inserted into the slot 4 on another base plate 1. During the insertion process, it is initially fixed by friction. At the same time, the limiting plate 42 slides on the inner wall of the base plate 1. With the cooperation of the compression spring 43 and the moving plate 44, the limiting plate 42 can be inserted into the inner wall of the slot 6 of the adjacent base plate 1, thereby further limiting the two adjacent sets of base plates 1 and ensuring the stability after splicing.

[0039] 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.
