However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a medical guide wire boosting device, comprising: a first shell 1 and a second shell 2, the first shell 1 and the second shell 2 are rotatably connected by a hinge, the upper surface of the first shell 1 is provided with a first guide wire groove 8, and the lower surface of the second shell 2 is provided with a second guide wire groove 9; a boosting assembly 3, the boosting assembly 3 comprises a mounting block 301, the rear surface of the mounting block 301 is fixedly connected to the outer surface of the first shell 1, the inner surface of the mounting block 301 is symmetrically provided with rollers 302, and the inner surfaces of the two rollers 302 are respectively fixedly connected with rotating rods 30 3. Two rotating rods 303 are rotatably connected to the mounting block 301 respectively. The outer surfaces of the two rotating rods 303 are fixedly connected with driven gears 304 respectively. The front surface of the mounting block 301 is fixedly connected with a mounting plate 308. The inner surface wall of the mounting plate 308 is provided with a motor 309. The output end of the motor 309 is fixedly connected with a rotating shaft 307. The outer surface of the rotating shaft 307 is fixedly connected with a driving gear 306. The outer surface of the driving gear 306 is meshed and rotatably connected with the outer surfaces of the two driven gears 304. A through hole 310 is provided on the outer surface of the mounting block 301. The outer surface of the roller 302 is in contact with the inner surface wall of the mounting block 301, and the outer surface of the roller 302 is rotatably connected with the inner surface wall of the mounting block 301. The front end surface of the rotating rod 303 passes through the rear surface of the mounting plate 308, and the outer surface of the rotating rod 303 is rotatably connected with the inner surface wall of the mounting plate 308.

[0024] The effect achieved by the entire embodiment 1 is that when the medical guide wire booster device is used, the medical guide wire needs to be loaded first, the tail end of the new medical guide wire is inserted into the through hole 310 through the catheter 305, and the motor 309 arranged in the inner wall of the mounting plate 308 is started. The output end of the motor 309 drives the rotating shaft 307 to rotate, so that the driving gear 306 is synchronized, and its outer surface respectively meshes and rotates the two driven gears 304 to rotate in the opposite direction to the driving gear 306. The two driven gears 304 rotate in opposite directions, and the corresponding rotating rods 303 rotate in the inner wall of the mounting block 301, which can drive the corresponding rollers 302, so that the medical guide wire in the through hole 310 can enter the first guide wire groove 8 and the second guide wire groove 9 driven by the two rollers 302 rotating in opposite directions, and spirally store in the first shell 1 and the second shell 2 along the curved guide wire groove. When the medical guide wire is used for boosting, the reverse operation can make the medical guide wire stored in the first shell 1 and the second shell 2 output outward.

[0025] Embodiment 2, as Figure 1-Figure 4As shown, the outer surface of the rotating shaft 307 passes through the front surface of the mounting block 301 and extends into the inner surface wall of the mounting block 301, and the outer surface of the rotating shaft 307 is rotatably connected to the inner surface wall of the mounting block 301. A conduit 305 is provided on the right surface of the mounting block 301, and the conduit 305 has the same diameter as the through hole 310, and the conduit 305 and the through hole 310 are matched. The radius of the first wire guide groove 8 and the second wire guide groove 9 are the same, and the first wire guide groove 8 and the second wire guide groove 9 are matched. The outer surface of the first shell 1 is fixedly connected to the fixed lock 6, the outer surface of the second shell 2 is fixedly connected to the fixed block 4, the lower surface of the fixed block 4 is fixedly connected to the clamping block 5, and the outer surface of the clamping block 5 is slidably connected to the inner surface wall of the fixed lock 6.

[0026] The effect achieved by the entire embodiment 2 is that, when in use, pressing the protrusion on one side of the card block 5 causes the card block 5 to deform and shrink, so that the card block 5 can be placed in the inner surface wall of the fixed lock buckle 6. At this time, one hand holds the handle on the lower surface of the first shell 1, and the other hand grabs the edge of the fixed block 4 and pulls it upward, so that the first shell 1 and the second shell 2 can be opened by rotating through the hinge, making it convenient for personnel to load guide wires or clean and disinfect the first guide wire groove 8 and the second guide wire groove 9.

[0027] Working principle: When in use, the tail end of the medical guide wire is inserted into the catheter 305, so that the medical guide wire is in the through hole 310, and the motor 309 is started. The output end of the motor 309 drives the driving gear 306 to rotate synchronously through the rotating shaft 307. The outer surface of the driving gear 306 meshes and rotates the two driven gears 304 respectively, so that the two rotating rods 303 can rotate correspondingly in the mounting block 301, and the two rollers 302 connected thereto will rotate synchronously towards each other, so that the medical guide wire in the through hole 310 can be moved into the first guide wire groove 8 and the second guide wire groove 9. The moving guide wire is moved between the two rollers 302. Under the mutual cooperation, it will enter the first shell 1 and the second shell 2 along the guide wire groove for loading and storage. When the medical guide wire is needed, the reverse operation can be performed to release the loaded and stored medical guide wire outward. Hold the handle set on the lower end face of the first shell 1, and press the edge of the card block 5 with the other hand to make it deform and shrink in the inner surface wall of the fixed lock 6. At this time, pull the protrusion of the fixed block 4 upward, so that the second shell 2 can be separated from the first shell 1 by rotating the hinge, which is convenient for personnel to load or clean the first guide wire groove 8 and the second guide wire groove 9, thereby improving the practicality of the medical guide wire booster device.
