[0030] As Figures 1 to 5 shown, a wire fixing device provided in this embodiment includes: a base 1, a mounting frame 2, a winding drum 3, and a wire mechanism 4

[0031] Among them, the mounting frame 2 is installed on the base 1, and a plurality of winding drums 3 for winding the wire are rotatably installed on the mounting frame 2 detachably. A plurality of wire mechanisms 4 are installed on the base 1 and correspond to the plurality of winding drums 3 one by one; the winding drum 3 is used for winding the wire or winding the wire around the winding drum 3. One end of the wire operation passes through the guidance of the wire mechanism 4 and then is inserted by the doctor, and the other end is wound on the winding drum 3 and wound or led out as needed; in the actual operation process, the wire can be manually coiled into a circle with a certain diameter first, then hung on the winding drum 3, and then the last wound end is led out through the guidance of the wire mechanism 4, which is flexible and practical and convenient to operate

[0032] As shown Figure 1 , 2 and Figure 4 show that a placement groove 31 for placing the guide wire is provided in the middle of the winding drum 3, which facilitates winding and placing the guide wire, making it in the middle position, reducing contact with other components, and reducing contamination. At the same time, for the disassembly and installation of the winding drum 3 and for conveniently and quickly winding and placing the guide wire, the winding drum 3 includes a winding shaft 32 and a guide wire drum 33. Among them, one end of the winding shaft 32 is abutted against the mounting bracket 2 through a spring 22. A mating groove 21 for abutting one end of the winding shaft 32 is provided on the mounting bracket 2. One end of the spring 22 is fixed in the mating groove 21. An embedding groove 34 for embedding the other end of the spring 22 is provided at one end of the winding shaft 32, which can effectively limit and position the winding shaft 32, and its connection with the mounting bracket 2 is elastic, facilitating disassembly and installation. And a non-circular clamping platform 35 is provided at the other end of the winding shaft 32. A clamping groove 23 matching the clamping platform 35 is provided on the mounting bracket 2. Since the clamping platform 35 is non-circular, in this embodiment, a hexagon is adopted, and the winding shaft 32 is stuck in the clamping groove 23 and will not rotate axially. And the guide wire drum 33 is coaxially rotatably mounted on the winding shaft 32. When the guide wire drum 33 rotates forward and backward on the winding shaft 32, the purpose of winding and unwinding the guide wire can be achieved, which is simple and efficient, has a good storage effect on the guide wire. When multiple guide wire drums 33 work simultaneously, multiple guide wires can be wound and unwound orderly at the same time, which is simple and practical, effectively avoiding interference between the guide wires and improving the intubation efficiency of doctors.

[0033] In order to more conveniently wind the guide wire and adjust the position of the guide wire, the mounting bracket 2 is movably adjustable and detachably mounted on the base 1, which is convenient for installation and disassembly and also facilitates disinfection and cleaning.

[0034] As shown Figure 1 , 3As shown in FIGS. 1 to 5, a plurality of wire mechanisms 4 are installed on the base 1. The wire mechanism 4 includes a wire column 41, a limiting ring 42, a wire ring 43 and a fastening member 44. Among them, the lower end of the wire column 41 is movably and adjustably installed on the base 1. Two limiting rings 42 are adjustably sleeved on the wire column 41 and respectively abut against opposite sides of the base 1. In this embodiment, the wire column 41 can move up and down through the base 1 to adjust the guiding height of the guide wire. The two limiting rings 42 can well limit and position the installation position of the wire column 41 on the base 1. When the height of the wire column 41 needs to be adjusted, just adjust the positions of the two limiting rings 42, which is simple and efficient. At the same time, the wire ring 43 is installed at the upper end of the wire column 41 and is correspondingly arranged with the winding drum 3. The wire ring 43 is provided with a wire through groove 45 for the guide wire to pass through. A protective ring 46 is provided on the inner wall of the wire through groove 45. The guide wire passes through the protective ring 46 and is led out therefrom, and then the doctor inserts the tube for operation. In order to facilitate the doctor's better operation, the wire ring 43 is movably installed on the wire column 41, that is, the wire ring 43 is rotatably installed on the wire column 41, and can guide the guide wire in multiple directions, which is simple and convenient. Moreover, a fastening member 44 is provided on the wire column 41. The fastening member 44 is made of rubber material and has a certain elasticity. It is divided into two mutually abutting parts by an arc-shaped dividing line and is used to clamp the guide wire. When the corresponding guide wire has not been operated or the operation is paused, the guide wire led out from the wire ring 43 can be clamped at the arc-shaped dividing line of the fastening member 44. The two parts of the fastening member 44 abut against each other, can tightly hold and fix the inserted guide wire, and the arc-shaped dividing line is a wavy line. After the guide wire is clamped, the guide wire cannot easily break away or move. When the doctor needs to use and operate, just take the guide wire out of the fastening member 44, without the doctor holding it by hand additionally, and it will not easily slip off to interfere with the doctor's other operations.

[0035] In order for the fastening member 44 to better clamp the guide wire, the fastening member 44 is arranged on the wire column 41 through a clamping seat 47. The clamping seat 47 is provided with a clamping groove 48. The fastening member 44 is fixed in the clamping groove 48. The two parts of the fastening member 44 are respectively in contact with the two side walls of the clamping groove 48, and there is a reaction force for abutting against the two parts of the fastening member 44, which can just clamp the guide wire between the two parts, which is simple and practical.

The guide wire coming out of the winding drum 3 passes through the wire guiding through groove 54 and is then guided and led out by the wire guiding ring 43. Through the guiding and transition of the wire guiding ring 53, the winding and unwinding of the guide wire on the winding drum 3 are more stable and orderly. At the same time, the wire guiding ring 53 has a good buffering effect on the winding and unwinding of the guide wire, ensuring the safe and orderly winding and unwinding of the guide wire by the winding drum 3, preventing the guide wire from being suddenly led out excessively or too fast, and the winding drum 3 not having time to rotate, and the guide wire on it being suddenly tightened and tightly wound around the winding drum 3, affecting the normal use of the guide wire and the normal operation of the doctor; whether the guide wire is coiled and suspended or tightly wound around the winding drum 3, it can be released orderly, normally and effectively, which is simple, efficient, practical and convenient.
