[0031] Embodiment 1:

[0032] See also Figure 1-Figure 8 The invention provides a technical solution: a telescopic vascular intervention guidewire control device, comprising a base 1, a mounting frame 2 is fixedly connected to the top outer wall of the base 1, and a pushing structure 3 is arranged in the mounting frame 2;

[0033] The pushing structure 3 includes a mounting plate 301, the outer wall of the mounting plate 301 is fixedly connected to the inner wall of the base 1, the outer wall of the mounting plate 301 is rotatably connected to a rotating plate 302, one end of the rotating plate 302 is rotatably connected to a connecting plate 303, a pushing plate 305 is arranged above the connecting plate 303, a plurality of pushing plates 305 are fixedly connected to a fixing block 304, a plurality of pushing plates 305 are connected to each other through the fixing block 304, one end of the connecting plate 303 away from the rotating plate 302 is connected to the outer wall of the fixing block 304, the inner wall of the base 1 is fixedly connected to a mounting plate 2 308, the outer wall of the mounting plate 2 308 is fixedly connected to a motor 1 309, and the motor 1 309 provides power for the movement of the rotating plate 302;

[0034] A moving plate 4 is arranged above the pushing structure 3, and a connecting plate 2 5 is fixedly connected between the outer walls of the moving plate 4, and the outer wall of the connecting plate 2 5 is slidably connected to the inner wall of the mounting frame 2, and multiple moving plates 4 are connected by the connecting plate 2 5, and a pushing space for the pushing plate 305 to move is formed between the outer walls of the multiple moving plates 4, and a spring 7 is fixedly connected to the outer wall of one side of the moving plate 4, and one end of the spring 7 is fixedly connected to the inner wall of the mounting frame 2;

[0035] A clamping device 8 is provided on the top of the movable plate 4, a fixing frame 9 is fixedly connected to the inside of the mounting frame 2 and located on one side of the movable plate 4, a clamping device 2 10 is fixedly connected to the top outer wall of the fixing frame 9, and a guide wire 12 is provided between the clamping device 1 8 and the clamping device 2 10.

[0036] Among them, the inner walls on both sides of the mounting frame 2 are provided with sliding grooves 6, and the outer wall of the connecting plate 2 5 is slidably connected to the inner wall of the sliding groove 6.

[0037] Among them, two connecting plates 303 are arranged below the pushing plate 305, the outer walls of the two rotating plates 302 are connected with pulleys 306 through rotating shafts, the outer walls of the pulleys 306 are sleeved with belts 307, the pulleys 306 are connected through the belt 307 transmission, and the output shaft of the motor 309 is connected to the pulley 306.

[0038] In this embodiment, the guide wire 12 is placed on the clamping device 18 and the clamping device 2 10. When the guide wire 12 needs to be pushed, the controller 11 starts the motor 1 309. The motor 1 309 drives the two rotating plates 302 to rotate synchronously through the pulley 306 and the belt 307. Since the rotating plate 302 is rotatably connected with the connecting plate 1 303, and the connecting plate 1 303 is connected to multiple pushing plates 305 through the fixed block 304, the rotation of the rotating plate 302 will drive the pushing plate 305 to move upward and forward.

The clamping device 1 8 clamps one end of the guide wire 12 and moves forward with the moving plate 4.

[0039] When the rotating plate 302 continues to rotate, the connecting plate 1 303 moves downward, and under the action of the spring 7, the clamping device 1 8 returns to its original position, and the pushing structure 3 starts to move downward and backward under the drive of the motor 1 309.

[0040] Embodiment 2:

[0041] This embodiment is a further optimization of embodiment 1. On the basis of embodiment 1, Figure 1-Figure 3 and Figure 7-Figure 8 As shown, the clamping device 8 includes a slide rail 801, the inner wall of which is rotatably connected to a bidirectional screw rod 802, a motor 803 is fixedly connected to an outer wall of one side of the slide rail 801, the output shaft of the motor 803 is connected to one end of the bidirectional screw rod 802, the inner wall of the slide rail 801 is slidably connected to a moving block 804, the inner wall of the moving block 804 is threadedly connected to the outer wall of the bidirectional screw rod 802, two moving blocks 804 are provided, the outer walls of the bidirectional screw rod 802 contacted by the two moving blocks 804 have opposite thread directions, and the top outer wall of the moving block 804 is fixedly connected to a clamping plate structure 805.

[0042] The clamping plate structure 805 is semicircular, and two clamping plate structures 805 form a circle. The inner side wall of the clamping plate structure 805 is provided with a rubber pad.

[0043] Among them, the structure of the clamping device 2 10 is the same as that of the clamping device 1 8.

[0044] In this embodiment, the guide wire 12 is placed on the clamping device 1 8 and the clamping device 2 10. When the guide wire 12 needs to be pushed, the clamping device 2 10 clamps the guide wire 12, and the controller 11 starts the motor 2 803. The motor 2 803 drives the bidirectional screw 802 to rotate. Since the outer wall threads of the bidirectional screw 802 contacted by the two moving blocks 804 are in opposite directions, the two moving blocks 804 will move toward each other along the slide rail 801, thereby driving the clamping plate structure 805 to approach and clamp one end of the guide wire 12.

[0045] Embodiment 3:

[0046] This embodiment is a further optimization of Embodiment 1 and Embodiment 2. Based on Embodiment 1, Figure 1-Figure 8 As shown, the outer wall of the movable plate 4 is fixedly connected with a pressure sensor. When the pushing structure 3 moves upward and forward, when the pressure sensor is squeezed, the clamping plate structure 805 on the clamping device 1 8 clamps the guide wire 12, and the clamping plate structure 805 on the clamping device 2 10 is controlled to open. When the pushing structure 3 moves downward and backward, when the pressure sensor loses squeezing, the clamping plate structure 805 on the clamping device 1 8 opens, and the clamping plate structure 805 on the clamping device 2 10 clamps the guide wire 12.

[0047] A controller 11 is disposed on one side of the base 1 , and the controller 11 is electrically connected to the motor 1 309 , the motor 2 803 , and the pressure sensor.

[0048] In this embodiment, when the pressure sensor on the moving plate 4 detects the thrust of the pushing plate 305, the controller 11 receives the signal of the pressure sensor, the clamping device 1 8 clamps the guide wire 12, and the clamping device 2 10 releases the guide wire. Under the cooperation of the rotating plate 302 and the connecting plate 1 303, the pushing plate 305 drives the clamping device 1 8 to move forward.

[0049] When the rotating plate 302 continues to rotate, the connecting plate 303 moves downward. Under the action of the spring 7, the clamping device 8 returns to its original position, and the pushing structure 3 starts to move downward and backward under the drive of the motor 309. When the pushing plate 305 is separated from the movable plate 4 and the pressure sensor loses its extrusion, the clamping device 8 releases the guide wire 12, and the clamping device 2 10 clamps the guide wire 12.

[0050] Working principle: When in use, the guide wire 12 is placed on the clamping device 1 8 and the clamping device 2 10. When the guide wire 12 needs to be pushed, the controller 11 starts the motor 2 803, and the motor 2 803 drives the bidirectional screw 802 to rotate. Since the outer wall threads of the bidirectional screw 802 contacted by the two moving blocks 804 are in opposite directions, the two moving blocks 804 will move toward each other along the slide rail 801, thereby driving the clamping plate structure 805 to approach and clamp one end of the guide wire 12.

[0051] The controller 11 starts the motor 309, and the motor 309 drives the two rotating plates 302 to rotate synchronously through the pulley 306 and the belt 307. Since the rotating plate 302 is rotatably connected with the connecting plate 303, and the connecting plate 303 is connected to multiple pushing plates 305 through the fixed block 304, the rotation of the rotating plate 302 will drive the pushing plate 305 to move upward and forward. When the pushing plate 305 moves upward and forward, it will push the moving plate 4 in contact with it to slide forward along the slide groove 6, and the spring 7 is stretched. The clamping device 8 clamps one end of the guide wire 12 and moves forward with the moving plate 4. When the pressure sensor on the moving plate 4 detects the thrust of the pushing plate 305, the controller 11 receives the signal of the pressure sensor, the clamping device 8 clamps the guide wire 12, and the clamping device 10 releases the guide wire. Under the cooperation of the rotating plate 302 and the connecting plate 303, the pushing plate 305 drives the clamping device 8 to move forward.

[0052] When the rotating plate 302 continues to rotate, the connecting plate 1 303 moves downward, and the clamping device 1 8 returns to its original position under the action of the spring 7. The pushing structure 3 starts to move downward and backward under the drive of the motor 1 309. When the pushing plate 305 is separated from the moving plate 4 and the pressure sensor loses its squeeze, the clamping device 1 8 releases the guide wire 12, and the clamping device 2 10 clamps the guide wire 12 to complete the handover of the guide wire. Through the precise control of the controller 11, the above process can be cyclically carried out to achieve continuous pushing and position adjustment of the guide wire 12 in the blood vessel. The control of the guide wire is achieved through the forward and backward and upward and downward telescopic movement of the pushing structure.

[0053] The above description is only a preferred specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the invention according to the technical scheme and inventive concept of the invention, which should be covered by the protection scope of the invention.
