[0055] Based on the previous embodiment, although the above embodiment can improve the convenience and efficiency of the guidewire catheter entering the guide needle, after the guidewire enters the human blood vessel, the external electric element adjusts the guidewire after entering the human blood vessel, which easily causes the swing amplitude and transportation speed of the guidewire to change, thereby puncturing the human blood vessel. In view of this, improvements are made on the basis of embodiment 1, and the improved technical solution is as follows.

[0057] A detection component 12 for detecting whether the guide wire catheter input is smooth is provided inside the lower guide component 9. The detection component 12 includes a movable groove opened inside the lower guide component 9. Rotating rollers 1201 are respectively provided on both sides of the lower guide component 9. The number of rotating rollers 1201 is set to four. The outer peripheral side walls of the rotating rollers 1201 are provided with circumferentially distributed pressure-sensitive strips 1202. The pressure-sensitive strips 1202 on a single rotating roller 1201 conflict with each other. The two ends of the two rotating rollers 1201 located on the same side are rotatably connected to a connecting rod 1203 through a locking assembly. The connecting rod 1203 is fixedly connected to the inner arm of the lower guide component 9 through a telescopic assembly 1204.

[0058] In this embodiment, the distance between the two conveying rollers II804 and the distance between the two conveying rollers I704 are both controlled by a hydraulic push rod, which pushes the drive motor III805 and the drive motor II705 to translate, so that the distance between the two conveying rollers II804 and the distance between the two conveying rollers I704 can be adjusted; the rotating roller 1201 is located inside the lower traction seat 901, the locking component is set as an electromagnetic latch, the connecting rod 1203 and the telescopic component 1204 are hinged, and a limit component is provided at the connection between the connecting rod 1203 and the telescopic component 1204, and the telescopic component 1204 is an electric telescopic rod; in the initial state, the locking component contracts, so that the rotating roller 1201 and the connecting rod 1203 are in an unlocked state; the limit component pops out, so that the telescopic component 1204 and the connecting rod 1203 are in a locked state; the rotating rollers 1201 located on both sides of the conveying pipe 903 are in contact with each other, and the electric telescopic rod is in a power-off state.

[0059] When in use, the guide wire is introduced from the conveying hole III802 into the middle of the conveying roller II804, and the guide wire goes downward and enters into the conveying hole II711 from the conveying hole I706. Since a conveying tube 903 is provided between the conveying hole II711 and the conveying hole IV902, the guide wire will directly enter into the conveying tube 903 after coming out of the conveying hole I706. Since two rotating rollers 1201 are provided on both sides of the conveying tube 903, and through holes corresponding to the rotating rollers 1201 are provided on the outer wall of the conveying tube 903, the rotating rollers 1201 located on both sides of the conveying tube 903 are fitted together through the through holes. After the guide wire enters the conveying tube 903, it gradually contacts the outer wall of the rotating roller 1201 located in the conveying tube 903 and squeezes the rotating roller 1201. Since the telescopic assembly 1204 and the connecting rod 1203 are in a locked state at this time, the electric telescopic rod is in a power-off state. state, so that in the process of relative squeezing between the guide wire and the rotating roller 1201, the rotating roller 1201 pushes the telescopic assembly 1204 to move toward the outer wall of the lower traction seat 901 through the connecting rod 1203, and then the electric telescopic rod is contracted. Since the outer peripheral side wall of the rotating roller 1201 is provided with pressure-sensitive strips 1202 distributed in an array, the control system determines the size of the guide wire by detecting the contraction amount of the electric telescopic rod. After detecting the size of the guide wire, the control system controls the hydraulic push rod to shorten the distance between the two conveying rollers II804 and the distance between the two conveying rollers I704, so that the two conveying rollers II804 and the two conveying rollers I704 can effectively clamp the guide wire, thereby avoiding the intermittent and slipping phenomena of the conveying rollers II804 and I704 in the process of conveying the guide wire.

[0060] After the guide wire and the guide needle are aligned, the control system's electric telescopic rod is energized to control the conveying roller II804 and the conveying roller I704 to rotate to convey the guide wire. During the process of conveying the guide wire by the conveying roller II804 and the conveying roller I704, since the rotating roller 1201 and the connecting rod 1203 are in a non-locked state, after the guide wire contacts the rotating roller 1201, the friction force generated between the rotating roller 1201 and the guide wire causes the rotating roller 1201 to rotate. Since the outer peripheral side wall of the rotating roller 1201 is provided with pressure-sensitive strips 1202 distributed in an array, the pressure-sensitive strips 1202 rotate synchronously with the rotation of the rotating roller 1201. The control system determines the running speed of the guide wire inside the blood vessel by detecting the number of pressure-sensitive strips 1202 that the guide wire passes through per unit time. If the guide wire and the pressure-sensitive strips 1202 pass through the blood vessel within a unit time, If the number of contacts is large, it means that the guide wire is running too fast. At this time, the control system controls the locking assembly to pop up, so that the rotating roller 1201 and the connecting rod 1203 are in a locked state, so that the rolling friction between the rotating roller 1201 and the guide wire is changed into sliding friction, thereby slowing down the movement speed of the guide wire. At the same time, when the control system detects that the number of contacts between the guide wire and the pressure-sensitive strip 1202 per unit time is large, it synchronously transmits an alarm signal; when the control system detects that the number of contacts between the guide wire and the pressure-sensitive strip 1202 per unit time is small, it means that the guide wire is in contact with the blood vessel wall during operation. At this time, the control system controls the driving motor III805 and the driving motor II705 to flip, and the conveying roller II804 and the conveying roller I704 to pull the guide wire to avoid excessive contact between the guide wire and the blood vessel wall and the guide wire penetrating the blood vessel.

[0061] When the guide wire runs to the bifurcation of the blood vessel, the control system controls the locking component to pop out, so that the rotating roller 1201 and the connecting rod 1203 are in a locked state; the limit component contracts, so that the telescopic component 1204 and the connecting rod 1203 are in an unlocked state; through the cooperation of the contrast agent, the mobile electric telescopic rod is controlled to be extended and retracted, thereby controlling the guide wire to move slightly inside the blood vessel, so that the guide wire enters the corresponding blood vessel bifurcation; for example, when the guide wire needs to deviate to the right, the control system controls the electric telescopic rods at the lower left side and the upper right side to extend, and the control system controls the electric telescopic rods at the upper left side and the lower right side to contract. At the same time, since the connecting rod 1203 is hinged to the electric telescopic rod, during the process of contraction and extension of the electric telescopic rod, the angle between the connecting rod 1203 and the electric telescopic rod is deflected, thereby facilitating the guide wire to enter the corresponding blood vessel bifurcation.
